 		f1f9199ff4 v0.37.7.0 fix wave: federated brains + autopilot safety + OAuth confidential clients (#1253) 
* fix(reindex-frontmatter): connect engine before query (#1225)

`createEngine()` from src/core/engine-factory.ts only constructs the
engine; callers MUST call connect() before any executeRaw. The
reindex-frontmatter CLI was constructing the engine and going
straight to countAffected, which crashed on PGLite with "PGLite not
connected. Call connect() first." even on --dry-run.

Fix follows the existing-command pattern (src/commands/auth.ts,
src/commands/backfill.ts, src/commands/integrity.ts all do the
same): pass toEngineConfig(cfg) into both createEngine() AND
engine.connect(), then engine.initSchema() (idempotent on a current
schema, ~1ms cost).

Pre-fix verification: codex outside-voice CF5 flagged the related
"can't import connectEngine from cli.ts" misdirection in the
original fix plan. This implementation uses the canonical sibling
pattern instead.

Regression test pinned at test/reindex-frontmatter-connect.test.ts.

* chore: bump VERSION to 0.37.7.0 + stub CHANGELOG

v0.37.5.0 claimed by #1229 (warsaw-v4); v0.37.6.0 by #1246
(OpenRouter recipe). v0.37.7.0 is the next free slot for this
fix wave.

CHANGELOG entry stubbed in user-facing voice per CLAUDE.md
"CHANGELOG voice + release-summary format" — ELI10 lead-first,
real fix details below. The "## To take advantage of v0.37.7.0"
block follows the v0.13+ self-repair pattern from CLAUDE.md.

* fix(subagent): short-circuit terminal-on-resume (#1151)

Bug: when the worker resumed a subagent job whose persisted last
message was an assistant turn with text-only content (no tool_use
blocks), the replay reconciler at subagent.ts:241-247 had no
branch for that case. The main loop then called messages.create
against a conversation ending in assistant role, which Sonnet 4.6+
rejects with HTTP 400 "This model does not support assistant
message prefill." 3 retries later → dead-letter, despite all the
job's work having committed in earlier turns.

@zscgeek's bug report pinned this exactly: dream-cycle Otter
corpus runs hit ~7% dead-letter rate, every dead job's last
subagent_messages row was a text-only synthesis summary listing
slugs that already existed in `pages`. Their proposed fix mirrors
this implementation.

Fix: add an else branch to the assistant-tail check that mirrors
the live-loop terminal logic at subagent.ts:440-447 — reconstruct
finalText from the persisted text blocks, return
stop_reason='end_turn' immediately. No LLM call, no schema change.

Two new regression cases:
  - text-only terminal on resume returns immediately with zero
    messages.create calls
  - tool-use replay path unchanged (existing behavior preserved)

Codex outside-voice (CF13) initially flagged this fix as
mis-targeted, claiming subagent.ts already handled the case.
/investigate run revealed the live-loop terminal at :440-447 was
covered but the REPLAY-path terminal at :241-247 was missing —
both branches need symmetric handling.

* fix(autopilot): scope lockfile to GBRAIN_HOME (#1226)

The autopilot lockfile was hardcoded at `~/.gbrain/autopilot.lock`
(via `process.env.HOME`), bypassing GBRAIN_HOME. Two brains pointed
at different GBRAIN_HOME directories still wrote to the same global
lockfile; one would silently take over the other on each restart.

Fix: route through `gbrainPath('autopilot.lock')` from
src/core/config.ts (imported aliased as gbrainHomePath since the
local `gbrainPath` var in installAutopilot references the CLI
binary path). The mkdirSync(`~/.gbrain`) call also routes through
the helper so the directory is created in the right place too.

Co-authored with @rafaelreis-r — same fix shape as PR #1227,
re-implemented against current master per the wave's
"re-implement, credit, close" workflow.

Tests cover: one GBRAIN_HOME → one canonical lock; two
GBRAIN_HOME values → two distinct locks; default fall-through
still works.

* feat(graph-query): foreign-edge footer + --include-foreign (#1153)

The graph-query CLI silently dropped edges to pages in other sources
on federated brains. Users had no signal those edges existed unless
they read the source code.

Fix:
- New --include-foreign flag (off by default, preserves the existing
  scoping contract; on = explicit cross-source traversal).
- After every traversal, count edges from rootSlug whose target page
  lives in a different source. When count > 0 AND user didn't opt in,
  emit a stderr footer:
    `(N edge(s) to foreign-source pages hidden; pass --include-foreign
     to include them)`
- The "no edges found" path also runs the count + footer so users
  discover foreign edges even when scoped traversal returned nothing.
- Thin-client path skips the count (engine query not available);
  future T1 work threads source resolution through MCP for that path.
- Single quotation correctness in count SQL: page_links table is
  `links` (not `page_links`); JOIN both endpoints to pages and compare
  source_id, NULL-safe via `IS NOT NULL` guards on both sides.
- Fail-open on missing source_id column for pre-v0.18 brains: return 0
  (no foreign edges to report) instead of throwing.

4 new test cases: footer fires on scoped query with foreign edge,
--include-foreign suppresses footer, zero-foreign no-footer case,
pluralization regression guard.

* feat(sources): `gbrain sources current` + tier attribution (#1222)

Federated-brain users running destructive ops (extract, import,
purge) need a way to verify which source they're targeting BEFORE
the op runs. Pre-fix, the only way was to grep config files or run
the op with --dry-run and inspect output.

New command:
  gbrain sources current             # human output
  gbrain sources current --json      # machine-readable
  gbrain sources current --source X  # show what an explicit --source
                                     # X would resolve to (validates
                                     # X exists in the sources table)

Output names BOTH the resolved source id AND which tier of the 6-tier
resolution chain won (flag / env / dotfile / local_path /
brain_default / seed_default), plus a `detail` line naming the
winning signal (e.g. "GBRAIN_SOURCE=dept-x" or ".gbrain-source" or
"/work/gstack/src").

Implementation:
- New `resolveSourceWithTier()` in source-resolver.ts as an additive
  variant of `resolveSourceId()`. Walks the same 6 steps in the same
  order; just returns `{ source_id, tier, detail? }` instead of bare
  string. Existing `resolveSourceId()` unchanged — all callers
  continue working.
- New `SOURCE_TIER_NAMES` const + `SourceTier` type export so the
  CLI, doctor (Tier 5 follow-up), and future MCP consumers share one
  vocabulary instead of inlining strings.
- Help text updated; `current` subcommand registered in dispatcher.

11 new tests pin the 6-tier ladder + priority semantics. Existing
19 source-resolver tests still pass (regression preserved).

Per codex CF3 (the existing src/core/source-resolver.ts was missed
in the original plan). Re-uses the existing helper instead of
inventing a duplicate.

* feat(extract): --source-id scopes extraction to one brain source (#1204)

Federated brain users running `gbrain extract` had no way to scope
extraction to one source. The DB path walks all sources together via
listAllPageRefs(), which is correct for cross-source resolution but
sometimes the user wants to extract per-source explicitly (e.g.
re-running extract on a specific source after a manual import).

The pre-existing `--source` flag is the data-source axis (fs|db) and
can't be repurposed. New flag `--source-id <id>` joins it on the
brain-source-id axis:

  gbrain extract all --source db --source-id alpha
    -> walks only alpha-source pages; extracts links + timeline
       from those, into the alpha source

Important: the resolver maps (allSlugs + slugToSources) stay built
from the FULL listAllPageRefs result, not the scoped subset. This
ensures qualified cross-source wikilinks like `[[other-src:slug]]`
still resolve correctly even when the extract walk is scoped — the
filter is on which pages we extract FROM, not what we can resolve TO.

Threaded through both `extractLinksFromDB` and `extractTimelineFromDB`
with backward-compat: callers passing no opts get the old behavior.

4 new test cases pin: walks-all-without-flag baseline,
alpha-only-when-scoped-to-alpha, beta-only-when-scoped-to-beta,
empty-set-on-unknown-source.

Note: #1204's wider "silent 0 links" report on federated brains has
additional facets beyond this flag (resolver path edge cases on
overlapping slugs). The scoped-walk fix gives users an explicit
workaround AND closes the per-source extraction gap.

* chore(todos): file v0.37.7.0 follow-ups (#1173, #1204, T5N)

Three items deferred from v0.37.7.0:

1. #1173 .sql indexing — verify-first gate found
   tree-sitter-sql.wasm missing from src/assets/wasm/grammars/.
   Dedicated wave needed: vendor the wasm, add .sql to walker
   filter, address slug-shape collision with #1172.

2. #1204 deeper investigation — wave added --source-id flag as
   workaround. Underlying silent-zero-links bug on unscoped
   federated extracts needs its own /investigate pass against
   a cross-source-duplicate-slug fixture.

3. Tier 5N doctor sweep for dead-lettered subagent jobs matching
   the #1151 fingerprint. Deferred to v0.37.8+ behind the islamabad
   doctor.ts conflict resolution.

* fix(sync): walker skips git submodule directories (#1169)

Sync walker descended into git submodules and indexed their markdown
content as if it belonged to the parent brain. Users with submodules
in their brain repo saw foreign content in their pages table.

Fix: pruneDir gains an optional `parentDir` arg. When set, the helper
stats `<parentDir>/<name>/.git` and skips the directory if `.git`
exists as a FILE (gitfile pointer — the canonical submodule shape).
Directories containing `.git` as a DIRECTORY (a real nested repo,
not a submodule) are descended into; the inner `.git` dir itself is
then dot-prefix-excluded.

Callers updated to pass parentDir:
- src/commands/extract.ts walkMarkdownFiles
- src/core/cycle/transcript-discovery.ts walker

Back-compat preserved: existing pruneDir(name) callers without
parentDir get the pre-v0.37.7.0 behavior unchanged.

Companion `.gitignore`-respect feature from PR #1159 (@jetsetterfl)
NOT in this wave — it would require adding the `ignore` npm package
as a dep, which the plan's "no new deps in this PR" gate excludes.
Filed as follow-up TODO for a dedicated wave.

5 new test cases pin the submodule shape + back-compat + nested-repo
ambiguity. Existing extract-fs / extract-db tests unchanged.

* docs(brain-routing): document 6-tier source resolution chain (#1222)

The convention skill didn't have a tier-by-tier reference for how
gbrain resolves the active source. Users running federated brains
had to read the source code to know which signal wins.

Added:
- Canonical 6-tier table (flag → env → dotfile → local_path →
  brain_default → seed_default) matching src/core/source-resolver.ts.
- Pointer to `gbrain sources current` (new in v0.37.7.0) as the
  verification command.
- The CLI-layer trust boundary note: operations.ts handlers don't
  read env/dotfile (preserves v0.34.1.0 source-isolation work for
  MCP callers).
- Per-command flag map: --source, --source-id (extract), and
  --include-foreign (graph-query).

* feat(import): --source-id flag routes pages to a brain source (#1167)

`gbrain import --source dept-x ./pages` silently fell back to the
default source because the CLI parser never consumed --source. PR
#707's design intent excluded the flag explicitly; users had no
signal their pages were going to the wrong place. #1167 + #1222
filed the regression.

Fix: parse `--source-id <id>` (matching v0.37.7.0 extract.ts T2's
naming convention — --source-id stays out of conflict with future
axes that may want --source). When set, the flag value wins over
any programmatic opts.sourceId; back-compat preserved for callers
that pass sourceId via opts only.

Also threaded into the positional-dir arg parser's flagValues set
so `--source-id <value> <dir>` doesn't treat <value> as the dir.

Note on related surfaces:
- `gbrain query "X" --source_id dept-x` already routed correctly
  via the operations.ts query op (added in v0.34) — no fix needed.
- `gbrain extract --source-id <id>` shipped in T2.
- `gbrain sync --source <id>` already worked (pre-existing).
- `gbrain sources current` (shipped in T4) is the verification
  tool — run it before destructive ops to confirm routing.

Closes the silent-fallback for the import path. Co-authored with
@tyad67-netizen (#1168), @hnshah (#1124, #1120), whose patches
informed the shape; re-implemented against current master per
the wave's "re-implement, credit, close" workflow.

3 new test cases pin: default-without-flag, --source-id-routes-correctly,
flag-value-not-treated-as-dirArg.

* fix(autopilot): reconnect classifier + launchd ThrottleInterval (#1162)

Pre-fix: when database_url was unset/malformed, the DB-health-check
reconnect loop logged `config.database_url undefined` forever
because the catch swallowed every error type uniformly. launchd's
KeepAlive=true respawned immediately on any exit, so even when
the process did exit, it came right back into the same bad state.
@colin477 reported the daemon-thrash pattern.

Two-part fix:

1. In-process error classifier — `classifyReconnectError(err)`:
   - `unrecoverable` (database_url missing/empty/malformed, auth
     failure, no-brain-configured): exit immediately with a clear
     stderr line. Pattern-matched against postgres / config-loader
     error shapes. Tests pin the matcher against the #1162
     fingerprint exactly.
   - `recoverable` (network blip, pool saturated, connection refused
     on a port coming up, Supabase 503): retry. Up to
     GBRAIN_AUTOPILOT_MAX_RECONNECT_FAILS (default 30 = ~5min) before
     finally giving up with `max_reconnect_fails_exceeded`.
   - Counter resets on every successful health probe or reconnect.

2. launchd plist gains `ThrottleInterval=60`. Combined with the
   in-process exit, launchd waits 60s before relaunching instead
   of immediate respawn. Pure-function `generateLaunchdPlist()`
   exported for tests.

16 new test cases:
- 11 classifier cases (database_url shapes, malformed URL, auth,
  role-does-not-exist with quoted name, network blip, pool
  saturated, 503, non-Error inputs, case-insensitivity)
- 5 plist generator cases (ThrottleInterval=60, KeepAlive
  preserved, wrapper path, XML escaping, StandardErrorPath).

Pre-existing autopilot-lock-path tests unchanged — both fixes
land cleanly side-by-side.

* fix(oauth): confidential clients via custom /token middleware (#1166)

v0.34.1.0 (#909) fixed PUBLIC PKCE clients (client_secret=undefined)
by normalizing NULL → undefined in getClient. Confidential clients
regressed: the MCP SDK's clientAuth middleware does plaintext
`client.client_secret !== presented_secret` compare, but gbrain
stores SHA-256 hashes, so the SDK's compare always failed for
authorization_code and refresh_token grants on confidential clients.
Result: /token returned `invalid_client` for every confidential
exchange.

Fix shape per locked-decision-5: custom /token middleware BEFORE the
SDK's authRouter, similar to the pre-existing client_credentials
handler. The middleware:

1. Detects confidential auth via `client_secret` in body
   (client_secret_post) OR `Authorization: Basic` header
   (client_secret_basic per RFC 6749 §2.3.1).
2. Falls through to the SDK when neither is present (public PKCE
   path stays canonical, preserves v0.34.1.0 behavior).
3. Calls new `verifyConfidentialClientSecret(clientId, presented)`
   on the provider which does SHA-256 hash compare ourselves
   (same shape as exchangeClientCredentials' existing hash check).
4. On verification success, calls existing
   `exchangeAuthorizationCode` / `exchangeRefreshToken` directly
   with the validated client.
5. RFC 6749 §5.2 error semantics: 401 invalid_client for auth
   failures, 400 invalid_grant for code/token problems.

Per CLAUDE.md "GBRAIN:RLS_EXEMPT" annotation contract: this surface
sits in front of the SDK's clientAuth and doesn't depend on the
SDK's plaintext compare working — the SDK's middleware never
fires for confidential paths the new middleware claims.

7 new test cases pin: correct-secret-returns-client, wrong-secret
opaque rejection, non-existent client, public-client refuses
the confidential path, case-sensitivity, soft-deleted revocation,
verify-then-exchange-refresh round-trip with second-use rejection.

* feat(doctor): 3 new checks — source routing + oauth + autopilot lock (T12/T13/T14)

Three v0.37.7.0 doctor checks landing in one atomic commit (single
file, shared merge-conflict surface with garrytan/islamabad-v3 per
locked decision 1):

1. source_routing_health (T12 / #1167):
   Sample non-default sources for pages; warn when a registered
   source has zero pages (silent-collapse-to-default fingerprint).
   D5 lock: total-sample cap of 200 pages across all sources, with
   per-source cap = min(50, ceil(200/N)) so a 20-source CEO brain
   pays 200 selects, not 1000. Fix hint paste-ready to
   `gbrain sources current --json` for verification.

2. oauth_confidential_client_health (T13 / #1166):
   Probe every oauth_clients row. Confidential clients (auth_method
   != 'none') must have a non-NULL client_secret_hash; if any row
   claims confidential auth but stores NULL hash, that's the
   pre-v0.37.7.0 regression. Public clients (auth_method='none')
   correctly keep NULL hash per v0.34.1.0 #909. Fix hint:
   `gbrain auth revoke-client + register-client` OR `gbrain upgrade`.
   Pre-OAuth schemas (missing oauth_clients table) skip gracefully.

3. autopilot_lock_scope (T14 / #1226):
   Detect stale ~/.gbrain/autopilot.lock outside the current
   GBRAIN_HOME. Codex CF11: dangerous to paste-ready `rm` without
   verifying the owning PID isn't a live process. Hint reads the
   PID file and gives the user a `ps -p <pid>` check before any
   delete — matches sshd-style stale-lock recovery hints.

9 new test cases pin the canonical paths. Pre-existing 80+ doctor
checks unchanged.

Expected to conflict with garrytan/islamabad-v3 at merge time. The
3 new check functions live in their own block far from the
islamabad skill_brain_first check; the conflict surface should be
limited to the `checks.push(...)` call site near the end of
runDoctor's DB-checks phase (~10 lines).

* fix(test): withEnv wrapper in source-resolver-with-tier (test-isolation lint)

The new source-resolver-with-tier.test.ts from T4 mutated
process.env.GBRAIN_SOURCE directly in two cases, which violates
scripts/check-test-isolation.sh R1 (env mutations leak across
parallel-loaded test files in the same shard process).

Fix: wrap both mutation sites in withEnv() from test/helpers/with-env.ts,
which saves+restores via try/finally per the canonical pattern in
CLAUDE.md.

Pure refactor — all 11 cases still green.

* docs: CHANGELOG voice tightening — strip meta-content from v0.37.1.0 entry

CLAUDE.md gains an IRON RULE for CHANGELOG entries: the changelog describes
what the user gets, not how the work happened. No mentions of review
processes, plan files, decision tags, migration version drama, or 'what we
caught and fixed before merging.' If a fact only exists because of the
development workflow, it does not belong in release notes.

Rewrite v0.37.1.0 entry to comply: cut the 'what we caught' section
(architectural review drama), the 'plan + reviews' bullet, and the
migration-renumbering aside. Entry shrinks 67 → 56 lines, every sentence
now answers 'what can I do / how do I use it / what should I watch for.'

Regenerated llms-full.txt to absorb the CLAUDE.md voice update.

* fix(sync): accept .tf / .tfvars / .hcl in CODE_EXTENSIONS

Terraform repos were invisible to `gbrain sync --strategy code` because
the three HCL-family extensions never reached the file walker. Silent
data loss — the user thinks the sync covered the repo but the IaC layer
was dropped on the floor.

detectCodeLanguage() returns null for these extensions, so the chunker
falls back to recursive (no tree-sitter grammar for HCL) — the same
path toml/yaml take.

Closes #878.

* fix(upgrade): run `bun update gbrain` from Bun's global install root

`gbrain upgrade --strategy bun` was failing on canonical
`bun install -g github:garrytan/gbrain` installs because `execSync('bun
update gbrain')` ran in the user's shell cwd. Bun's update operates on
whatever package.json it finds via cwd-walk, so a user not standing in
the global root got "No package.json, so nothing to update".

resolveBunGlobalRoot() returns the right directory:
1. `$BUN_INSTALL/install/global` when set (operator override).
2. `~/.bun/install/global` (Bun's documented default).
3. Walk up from realpath(argv[1]) looking for `node_modules/gbrain` —
   handles non-standard installs without trusting argv naming.

execFileSync replaces execSync (no shell), with cwd pinned. Error path
prints the exact `cd && bun update` recovery command instead of a vague
hint.

Closes #1029. Cherry-picked from PR #1032.

* fix(config): redact sensitive values in `config set` output (closes #892)

`gbrain config set openai_api_key sk-...` was echoing the full key to
stderr via `console.log('Set %s = %s', key, value)`. Shell scrollback and
tmux scroll buffers commonly retain stderr for hours; a screen-share or
shoulder-glance during set leaked the secret.

The `show` path already redacted but used a naive `.includes('key')`
substring check that would mask 'monkey' or 'parsekey' (no false-negative
but ugly).

Single source of truth: `isSensitiveConfigKey()` uses a word-boundary
regex (`(^|[._-])(key|secret|token|password|pwd|passwd|auth)([._-]|$)/i`)
so 'openai_api_key' matches but 'monkey' doesn't. `redactConfigValue()`
composes the postgresql:// URL redactor + sensitive-key check, used by
both `show` and `set`. Helpers exported for unit tests.

Closes #892. Cherry-pick of @sharziki's PR #918 (config.ts hunk only —
the extract.ts walker change in that PR is unrelated and tracked in #202).

* fix(oauth): throw InvalidTokenError so bearerAuth returns 401, not 500

`verifyAccessToken` was throwing bare `Error` on expired or invalid
tokens. The MCP SDK's `requireBearerAuth` middleware catches
`InvalidTokenError` and returns 401 with WWW-Authenticate; bare Error
falls through to 500. Result: legitimate clients with stale tokens hit
500-not-401, so token-refresh logic (which keys off 401) never fires.

Two call sites in verifyAccessToken: token-expired path and
invalid-token path. Both now throw InvalidTokenError. Existing tests
continue to pass because they assert on the throw, not the message class.

* fix(serve): return 405 on GET /mcp instead of 404

MCP Streamable HTTP spec says GET /mcp opens an optional SSE backchannel
for server-initiated messages. gbrain's transport is stateless and
doesn't push server-initiated messages, so per spec we MUST return 405
with Allow: POST, DELETE — not 404. Probing clients (claude.ai, etc.)
distinguish "endpoint exists, no SSE channel" from "endpoint missing"
on this status code; 404 makes them give up.

* fix(doctor): resolve whoknows fixture from module location, not cwd

`gbrain doctor` warned about a missing whoknows fixture for every install
that wasn't standing in the gbrain source repo at run time — which is
everyone. The check used `process.cwd()` to locate the fixture, so any
real user (running doctor against `~/.gbrain`) saw a spurious warning.

`resolveWhoknowsFixturePath()` walks up from `import.meta.url` looking
for the source-repo signature (`src/cli.ts` + `skills/RESOLVER.md`),
respects `GBRAIN_WHOKNOWS_FIXTURE_PATH` env override (absolute or
cwd-relative), and returns null with an actionable warning when the
fixture can't be located.

* fix(frontmatter): centralize --fix backups under ~/.gbrain/backups/

`gbrain frontmatter validate --fix` and `gbrain frontmatter generate
--fix` wrote `<file>.bak` siblings into the source tree. Users running
gbrain over a brain repo found .bak files scattered through people/,
companies/, etc. that broke gitignore expectations and showed up in
`git status` after every fix pass.

Backups now land under `~/.gbrain/backups/frontmatter/<run-id>/<rel>.bak`
with an iso-week-sorted run-id so a multi-fix session keeps the same
parent directory. Backup directory + per-file structure mirrored from
the original file's relative path. The .bak safety contract is intact
for both git and non-git brain repos.

Also adds `--include-catch-all` opt-in to `frontmatter generate` so the
default catch-all rule (`type: note`) is no longer applied to arbitrary
workspace documents that happen to live under a brain root.

* fix(config): use path.isAbsolute() for GBRAIN_HOME on Windows

The GBRAIN_HOME validator rejected every valid Windows path (`C:\\Users\\...`,
`D:\\gbrain`, etc.) because it used `trimmed.startsWith('/')` to check for
absoluteness — only POSIX absolute paths pass that. `path.isAbsolute()` is
the cross-platform check.

Same fix for the `..` traversal check: split on both `/` and `\` so
Windows path separators don't sneak `..` through.

* fix(ai): warn only for the configured embedding provider, not all recipes

Gateway construction was warning on stderr for every recipe with an
embedding touchpoint missing max_batch_tokens — including providers the
brain isn't using. Users on Voyage saw noise about OpenAI / Google /
DashScope / etc. recipes that never get loaded.

Filter the warning to recipes whose provider id is referenced by
`embedding_model` or `embedding_multimodal_model` in the active config.
The structural protection against forgetting max_batch_tokens stays in
place for the recipes that actually run; the noise for unrelated recipes
goes away.

* fix(sync): skip git pull when repo has no origin remote

`gbrain sync` ran `git pull` unconditionally and printed scary stderr
on every cycle for brains that have no `origin` remote (local-only
workflows, single-machine setups, brains initialized via `gbrain init
--pglite` against an arbitrary directory). The pull failed harmlessly
but the noise was confusing and made operators think sync was broken.

`hasOriginRemote()` probes `git remote get-url origin` with stdio
ignored; on failure (`no such remote`), skip the pull, print a single
informational line, and proceed with the local working tree.

* fix(query): drain cache writes before CLI exit

The query cache write was fired with `void promise.catch(...)` — true
fire-and-forget. On a fast CLI invocation (`gbrain query <q>` exits in
~50ms), the process terminates before the cache write commits. Result:
the cache effectively never warms from CLI use; every query is a miss.

`awaitPendingSearchCacheWrites()` tracks each in-flight cache write in a
module-level Set. The CLI dispatcher awaits the set after `query`
finishes formatting output but before the process exits. MCP server path
unchanged (long-lived process, fire-and-forget remains correct).

* fix(backlinks): dedupe (source, target) pairs within a single source page

A source page that mentions the same entity N times produced N
duplicate "Referenced in" lines on the target. `extractEntityRefs`
returns one EntityRef per occurrence, and the per-ref `hasBacklink`
check reads a snapshot of `target.content` that's frozen at outer
scope — so every iteration sees "no backlink yet" and appends another
gap. The cumulative effect on a long meeting note with multiple
mentions of the same person was visible in PRs landing 3-5 identical
Timeline entries.

* fix(dream): audit backlinks without mutating pages during cycle

The dream/autopilot maintenance cycle ran the backlinks phase in 'fix'
mode, which writes "Referenced in" timeline bullets into entity pages
every sync. The graph extractor + auto-link path is the canonical link
store during sync/dream/autopilot — the legacy filesystem fixer wrote
markdown that fought with both the user's manual edits and the graph
layer's own timeline.

Cycle now runs backlinks in 'check' mode (audit-only); the materializer
remains available via `gbrain check-backlinks fix` for users who really
want markdown backlinks committed to disk.

zshenv is the canonical place for env vars in zsh on macOS — zshrc is

reach a non-interactive subprocess like the autopilot wrapper. Users
who exported GBRAIN_DATABASE_URL, OPENAI_API_KEY, or ANTHROPIC_API_KEY
in zshrc and assumed autopilot would inherit them hit silent missing-
secret failures on the LaunchAgent.

`gbrain apply-migrations list`, `gbrain apply-migrations --dry-run`, and
the "All migrations up to date" path were returning from the async
function but never calling `process.exit(0)`. The CLI dispatcher in
cli.ts treated the implicit fall-through as exit 1 when the parent
process inspected status via shell scripts, breaking automation that
gates on `apply-migrations list && do-something`.

Three call sites: list, dry-run, and the no-op path. All three now
exit(0) explicitly.

* fix(sync): scope auto-embed to source on incremental syncs

`gbrain sync --source-id X` triggered auto-embed for the affected slugs
but `runEmbed` ran with no `--source` flag, so it fell back to the
default source. For non-default-source syncs the page row lives at
(sourceId, slug) — the embed code saw "Page not found" for the right
slug under the wrong source, swallowed the error as best-effort, and
the sync result reported `embedded: 0` for the wrong reason.

`buildAutoEmbedArgs(slugs, sourceId)` is the new helper: when sourceId
is set, prepends `--source X`. Exported for the regression test.

* fix(query): honor source_id with no-expand for cross-source search

Two related corrections:

1. `gbrain query --no-expand` parsed `--no-expand` as the literal key
   `no_expand` instead of negating the boolean `expand` param. Result:
   the flag was silently ignored and expansion always ran. Now any
   `--no-<key>` where `<key>` is a boolean param flips it false.

2. The `query` op's source-id resolution treated `ctx.sourceId` as
   authoritative, so an explicit per-call `source_id` was overridden by
   the federated read scope. Now per-call `source_id` wins;
   `source_id=__all__` is an explicit opt-out for local cross-source
   search.

* fix(doctor): child-table orphan detection (closes #1063)

The autopilot orphans phase detects orphan PAGES (no inbound links via
page-graph) but never scans FK-child tables. After a bulk delete or a
pre-FK-migration code path, orphan rows can persist indefinitely in
content_chunks, page_versions, tags, takes, raw_data, timeline_entries,
or links — all declared ON DELETE CASCADE, so any orphan row is
unexpected.

`childTableOrphansCheck` enumerates 10 FK columns across 8 tables:
- 8 NOT NULL columns (cascade): any value not in pages.id is an orphan.
- 2 nullable SET NULL columns (links.origin_page_id, files.page_id):
  NULL is valid; only NOT-NULL-but-missing-in-pages counts.

Surfaces paste-ready cleanup SQL when orphans are found.

* fix(autopilot,cycle): stop respawn-storm from steady-state 'partial' cycles

Two compounding bugs under KeepAlive=true:

1. Autopilot tripped its circuit breaker on cycle.status === 'partial',
   not just 'failed'. 'partial' means at least one phase warned/failed
   while others ran — a soft signal, not fatal. On every cycle that
   warned, autopilot logged a failure and the supervisor respawned the
   worker.

2. The orphans phase emitted 'warn' when `count > 20` orphan pages.
   That threshold was tuned for small dev brains; on any corpus past a
   few hundred pages it fires every cycle in steady state. Together
   with bug 1, this produced visible respawn storms.

Fix:
- Autopilot trips only on cycle.status === 'failed'.
- Orphans phase warns by ratio: orphans / total_pages > 0.5 (the real
  "your graph fell apart" signal), not by absolute count.

* fix(ai): reject partial embedding responses before indexing

`embedSubBatch` only validated the FIRST embedding's dimension and never
asserted the response length matched the input length. If a provider
returned fewer embeddings than requested (rate-limit truncation,
malformed response, etc.), the gateway silently indexed an offset-shifted
result — every page after the missing index got the embedding of a
different page's chunk.

Two new guards:
1. `result.embeddings.length === texts.length` — fail loud if any count
   mismatch, with a paste-ready retry hint.
2. Validate dim on EVERY embedding, not just the first.

Pass grantTypes / redirectUris through to registerClientManual. When

* fix(extract-facts): treat slugs:[] as no-op, not unscoped full-walk

`runExtractFacts` checked `opts.slugs && opts.slugs.length > 0` to
decide between scoped and full-brain walk. Both `undefined` (caller
omits → full walk intended) AND `[]` (sync no-op → zero work intended)
fall through to the same `else` branch and triggered
`engine.getAllSlugs()`.

On a multi-thousand-page brain, the unintended full walk exceeded
the autopilot-cycle ~600s timeout and dead-lettered the job — visible
in production as `[cycle.extract_facts] start` followed by silence
until `Autopilot stopping (cycle-failure-cap)`.

Use presence (`opts.slugs !== undefined`), not truthiness, to
distinguish the two modes. Empty array is a real incremental no-op.

Closes #1096. Three regression cases in test/extract-facts-phase.test.ts:
slugs=[] no-op, slugs=undefined still walks, slugs=['a'] walks just one.

* fix(serve): embed admin/dist into binary; serve from manifest (closes #1090)

Pre-fix, /admin returned 404 on every globally-installed binary because
serve-http.ts:780 resolved admin/dist via process.cwd(). The admin SPA
files are checked into git but `bun build --compile` does NOT embed
arbitrary directories — only assets imported via `with { type: 'file' }`
ESM imports land in the compiled binary.

Wire:

- scripts/build-admin-embedded.ts walks admin/dist/, emits
  src/admin-embedded.ts with one `with { type: 'file' }` import per
  file + a manifest map (request path → resolved path + mime).
  Auto-invoked by `bun run build:admin`.

- src/admin-embedded.ts is the auto-generated module. Bun resolves
  every file: import to a path that works at runtime inside the
  compiled binary (same pattern as src/core/chunkers/code.ts WASM
  imports).

- serve-http.ts switches to two-tier resolution: cwd-relative
  admin/dist for dev (Vite hot-rebuild), embedded manifest otherwise.
  Embedded path reads bytes lazily and caches per-asset for the
  lifetime of the process.

- scripts/check-admin-embedded.sh CI gate re-runs the generator and
  fails on drift (mirrors check-wasm-embedded.sh). PRs that rebuild
  admin/dist but forget to regenerate the embedded module fail loud.

- package.json wires build:admin-embedded + check:admin-embedded.

* test(source-id): lock in routing regression coverage (closes #891 #978 #1078)

Audit of every page write path (sync, embed, extract, dream, autopilot,
wikilinks, tags, chunks) confirmed that sourceId already threads
correctly through importFromContent → engine.putPage → SQL INSERT
since v0.18.0. The original bug reports from #891, #978, #1078 were
real at the time and got swept by the multi-source refactor; today's
master is correct.

This commit locks in that correctness with six PGLite regression cases
(no Postgres fixture needed; runs in CI everywhere):

1. importFromContent({sourceId:"work"}) lands at source_id=work, not
   the silent 'default' fallback.
2. Two sources hold the same slug independently.
3. Omitting sourceId falls through to 'default' (legacy contract).
4. Chunks land under the requested source.
5. Tags land under the requested source.
6. FK integrity smoke (originally #1078).

The earlier issue reports stay closed by the existing threading; this
suite ensures any future refactor of the write path can't silently
re-introduce the wrong-source-default bug. The 90-minute write-path
audit budget from the plan resolves here.

* fix(apply-migrations): unblock PGLite chain (closes #1100)

`gbrain apply-migrations --yes` was wedging on the v0.11.0 (Minions)
schema phase for PGLite installs. Two compounding bugs:

1. `apply-migrations` pre-flight schema-version warning connects to
   PGLite to read config.version, then disconnects. The brief lock
   hold races with downstream subprocess spawns that try to re-acquire
   it; the 30s lock timeout fires before the parent fully releases.
   Pre-flight is a *warning*; on PGLite it adds no information the
   orchestrators don't already handle. Skip the probe for PGLite.

2. v0.11.0 phase A spawned `gbrain init --migrate-only` as an execSync
   subprocess to apply schema migrations. PGLite is single-writer;
   the subprocess inherits HOME and tries to lock the same DB. On
   Postgres this works (concurrent connections OK); on PGLite it
   deadlocks. Route in-process for PGLite — create + connect +
   initSchema + disconnect directly, skipping the subprocess hop.
   Postgres keeps the legacy execSync path.

Verified: fresh PGLite install now walks the full migration chain
through v0.32.2 (Facts SoR) and lands "All migrations up to date" on
re-run.

Closes #1100.

* fix(serve): bootstrap token env override + suppress flag (closes #1024)

`gbrain serve --http` regenerated the admin bootstrap token on every
restart and printed it to stderr. In supervisor-managed production
deployments (LaunchAgent, systemd, k8s) every restart leaks the value
into log aggregators and rotates the access for any agent that paste-
copied it.

Two new knobs:

- **GBRAIN_ADMIN_BOOTSTRAP_TOKEN** env var: when set, used as the
  bootstrap secret instead of a fresh per-process token. Validated:
  must match `^[A-Za-z0-9_-]{32,}$` (32-char minimum), else refuse to
  start with a paste-ready generator hint. Failing closed beats
  silently accepting a weak token.

- **--suppress-bootstrap-token** CLI flag: suppresses the printed
  token line entirely. Operator takes responsibility for tracking the
  value out-of-band.

Startup banner now reflects the chosen source:
- `Admin Token: suppressed` when the flag is set.
- `Admin Token: from $GBRAIN_ADMIN_BOOTSTRAP_TOKEN` when env-sourced.
- Full token print only when both are absent (default behavior, dev
  installs).

Closes #1024.

* fix(config): migrate legacy 'provider' + 'model' to 'embedding_model'

Pre-v0.32 docs and some community templates used a config shape:

  { "provider": "voyage", "model": "voyage-4-large" }

The canonical shape (since the v0.31.12 gateway seam) is:

  { "embedding_model": "voyage:voyage-4-large" }

Users on the legacy shape hit silent fallthrough to the hardcoded
OpenAI default; sync + embed errored out with "OpenAI embedding
requires OPENAI_API_KEY" regardless of their actual provider config.

loadConfig() now translates the legacy keys at parse time:
- emits a one-line stderr nudge with the paste-ready canonical key
- preserves the rest of the config unchanged
- skipped when `embedding_model` is already set (forward-compat)

Closes #1086.

* chore(test): quarantine upgrade tests (process.env mutation)

PR #1032's cherry-picked tests use the static-snapshot + try/finally
pattern for env vars instead of the project's withEnv() helper. The
test-isolation lint catches process.env mutations outside withEnv to
prevent cross-test leakage in parallel runs.

Renaming to *.serial.test.ts (the quarantine convention) is the
documented out: runs sequentially, no cross-file race. A future cleanup
PR can migrate the tests to withEnv() and drop the quarantine.

* fix(test): update brain-writer .bak assertion for centralized backup path

The v0.36.x frontmatter backup change (bd60cdf6 — closes #902) moved
.bak files from sibling-of-source to ~/.gbrain/backups/frontmatter/...
The old test still asserted on the sibling path, so CI failed even
though the production behavior was correct.

Updated assertion contract: backup lands under the injected backupRoot
(test-isolated), the returned backupPath ends in .bak and exists, and
no sibling .bak is created next to the source file. The pre-fix
sibling-path is now a negative assertion.

* test(fix-wave): close test gaps surfaced by post-ship audit

After the fix-wave shipped, an audit found 11 commits with no new test
file. Some were inherently structural (build pipelines, shell content)
or had existing test coverage that worked either way; others had real
regression risk with no guard. This commit closes the gaps that matter.

New regression tests for:

- OAuth `verifyAccessToken` throws `InvalidTokenError` (not bare Error)
  on both expired and unknown token paths. Pre-fix, the SDK's
  `requireBearerAuth` middleware fell through to 500 instead of 401 →
  client token-refresh logic never fired (#935).

- `loadConfig` translates legacy `{provider, model}` config shape to
  the canonical `embedding_model: <provider>:<model>`. 3 cases: pure
  legacy → migrated; canonical wins over legacy when both present;
  canonical-only is untouched. Pre-fix, Voyage/Cohere/Mistral users
  silently fell through to OpenAI (#1086).

- `configDir` rejects relative paths; rejects `..` segments via both
  separators (regression guard for the Windows path acceptance fix
  #1019 / cherry-pick #1083).

- `resolveBootstrapToken` (new exported helper extracted from
  `runServeHttp`). 9 cases: unset env generates fresh, valid env
  accepted, hyphens/underscores accepted, < 32 chars rejected, special
  chars rejected, whitespace trimmed, empty string rejected, 32-char
  boundary accepted, 31-char one-short rejected. Security-critical
  validation surface (#1024).

- GET /mcp returns 405 with `Allow: POST, DELETE` (E2E case in
  `serve-http-oauth.test.ts`). Pre-fix, claude.ai and other probing
  MCP clients saw 404 and gave up (#1076).

- apply-migrations `process.exit(0)` on list / dry-run / up-to-date
  paths. Source-shape assertion locks the rule in; shell scripts
  gating on `$?` work (#1062).

- Autopilot wrapper sources `~/.zshenv` BEFORE `~/.zshrc`. zshenv is
  the canonical place for env vars in non-interactive zsh; without
  this ordering, LaunchAgent subprocesses never inherit secrets
  exported in zshrc (#966).

- `test/fix-wave-structural.test.ts` consolidates source-shape
  regression guards for fixes whose behavior is hard to runtime-test
  without heavy mocking: query cache drain (#1125), admin embed
  manifest + handler (#1090), admin register-client PKCE branch
  (#1077), PGLite v0.11.0 phase A in-process routing (#1100), query
  `--no-expand` negation (#1124). 9 source-grep assertions.

Refactored `runServeHttp` to extract `resolveBootstrapToken` as a pure
helper. The boot path now consumes the helper's tagged-union result
({kind:'ok'|'error'}); side effects (`process.exit`, `console.error`)
moved to the caller. Unit-testable without spinning up Express.

Test counts: oauth 71 (was 69), config 20 (was 14), apply-migrations
19 (was 18), autopilot-install 5 (was 4), serve-http-bootstrap-token
9 (new file), fix-wave-structural 9 (new file). Net: +28 cases across
6 files; +1 new exported function with full coverage.

Remaining audit gaps (deferred):
- e82dda0a admin embed E2E (post-deploy curl smoke covers this)
- d93fa81d apply-migrations PGLite chain E2E (already smoke-tested
  manually in the original commit; subprocess test would be flaky in
  CI without DATABASE_URL gating)

* test: close the two deferred E2E gaps from the post-ship audit

Both gaps now have real behavior coverage. No DATABASE_URL needed (PGLite
engine), so they run in standard unit CI alongside the rest of the suite.
Serial quarantine because both spawn subprocesses + bind ports / write
tmpdirs.

test/admin-embed-spawn.serial.test.ts (4 cases, ~6s wall-clock):
  - Spawns `gbrain serve --http` from a fresh tmpdir so `process.cwd()/
    admin/dist` does not exist — this forces the embedded-manifest
    branch (the one under test). Pre-fix, this exact setup hit 404.
  - GET /admin/ → 200 + SPA shell HTML (title + #root div), content-type
    text/html.
  - GET /admin/index.html → same body via explicit path.
  - GET /admin/agents → SPA fallback returns index.html for deep links.
  - GET /admin/api/stats → NOT 200 (regression guard: SPA fallback must
    not swallow /admin/api/* routes and silently return HTML to a JSON
    client). Closes #1090.

test/apply-migrations-pglite-spawn.serial.test.ts (3 cases, ~25s):
  - Seeds a fresh PGLite config in a tmpdir, runs `gbrain init
    --migrate-only` + `gbrain apply-migrations --yes --non-interactive`.
    Pre-fix this hit "GBrain: Timed out waiting for PGLite lock" because
    apply-migrations' pre-flight probe + v0.11.0's phase A subprocess
    both wanted the single-writer lock.
  - Asserts exit 0, no "Timed out" string, no "Phase A failed" string,
    brain.pglite file written.
  - Re-run case: idempotent — "All migrations up to date" exits 0
    (also locks in the #1062 exit-code fix end-to-end).
  - --list path exits 0 (third leg of the #1062 contract).
  Closes #1100.

* fix(test): consolidate PGLite spawn test to one end-to-end pass

CI failed on test/apply-migrations-pglite-spawn.serial.test.ts (Ubuntu,
bun 1.3.14). The previous shape ran 3 tests × ~3 spawns each. Each
`bun run /abs/src/cli.ts` from a tmpdir cwd pays a full parse/transpile
cost (no near-cwd .bun cache); on Ubuntu CI that compounds past the
runner's per-test budget.

Consolidated to ONE test that exercises the full lifecycle in one
brain: init --migrate-only → apply-migrations --yes → re-run → --list.

Four spawns instead of eight. Local wall-clock: 32s → 11.5s. All four
assertion buckets preserved: no PGLite lock timeout, no Phase A
failure, brain.pglite written, idempotent re-run "All migrations up
to date" exits 0 (#1062 end-to-end), --list exits 0.

Per-test timeout 480_000ms as insurance against the runner's

end-to-end but fails on Ubuntu/bun 1.3.14 in 4.92s with apply.exitCode
= 1 — fast enough that something is failing early, not timing out.
The runCli helper captured stdout+stderr but never printed them, so
the CI log only showed the bare assertion failure.

This commit prints the captured streams from BOTH init and apply
when the exit code mismatches expectation. After the next CI run we
can read the actual error message and diagnose the Ubuntu-specific
failure mode (likely BUN_INSTALL / HOME / PGLite WASM env quirk).
No behavior change; pure diagnostic output gate on failure.

* fix(test): shim `gbrain` on PATH for PGLite spawn test

Root cause of the Ubuntu CI failure: the v0.11.0 orchestrator's phase B
runs `execSync('gbrain jobs smoke')`. PGLite phase A now routes
in-process (the #1100 fix), but phase B and several follow-up phases
still shell out to the `gbrain` binary on PATH. Locally the binary
resolves via `bun link`; on CI Ubuntu it does not exist on PATH, so
execSync exits 127 → orchestrator returns 'failed' → apply-migrations
exits 1. Test failed at 4.92s with exitCode=1, well before any timeout.

Verified locally by removing ~/.bun/bin/gbrain to simulate CI:
  pre-shim:  apply.exitCode=1 (same as CI)
  post-shim: apply.exitCode=0 in 8.4s

The shim writes a tiny `gbrain` executable to a tmpdir that just
`exec`s `bun run <repo>/src/cli.ts "$@"`. Prepended to PATH for the
spawned subprocesses. Mirrors the production contract (gbrain on
PATH) without depending on `bun link` having run in the CI image.

Diagnostic dump from the previous commit stays — useful insurance for
the next time something silently fails inside a spawned binary.

 		3a0e1116e7 v0.36.1.0 Hindsight calibration wave: brain learns how you tend to be wrong (#1139) 
* schema: v0.36.0.0 Hindsight calibration tables (migrations v67-v71)

Foundation commit for the Hindsight-inspired calibration wave. Adds four
new tables + one perf index, all source-scoped from day 1 per v0.34.1
discipline:

- calibration_profiles (v67): per-holder LLM-narrative aggregation of
  TakesScorecard data. published BOOL gates E8 cross-brain mount sharing
  (default false). grade_completion REAL surfaces partial-grade state to
  the dashboard. active_bias_tags TEXT[] with GIN index feeds E3 (calibration-
  aware contradictions) and E7 (real-time nudge matching).

- take_proposals (v68): propose_takes phase queue. Idempotency cache via
  (source_id, page_slug, content_hash, prompt_version) unique index mirrors
  the v0.23 dream_verdicts pattern. proposal_run_id supports --rollback by
  run. dedup_against_fence_rows JSONB audit column records what canonical
  takes the LLM was told to dedupe against at proposal time.

- take_grade_cache (v69): grade_takes verdict cache. Composite PK on
  (take_id, prompt_version, judge_model_id, evidence_signature) — prompt
  edits OR evidence changes cleanly invalidate prior verdicts. applied=false
  default + auto-resolve-off-by-default (D17) means every fresh install
  needs operator opt-in before grade verdicts mutate the takes table.

- take_nudge_log (v70): E7 nudge cooldown state. Polymorphic FK — a nudge
  fires on either a canonical take OR a pending proposal (CDX-5 fix). CHECK
  constraint enforces exactly-one-set. channel column lets future routing
  (webhook, admin SPA toast) reuse the same cooldown semantics.

- takes_resolved_at_idx (v71): partial index for the Brier-trend
  aggregation queries. Engine-aware handler — Postgres uses CONCURRENTLY
  to avoid the ShareLock; PGLite uses plain CREATE.

Every table carries wave_version TEXT NOT NULL DEFAULT 'v0.36.0.0' so the
v0.36.0.0 calibration --undo-wave command (lands later in the wave) can
reverse just this wave's writes.

Plan: ~/.claude/plans/system-instruction-you-are-working-rippling-knuth.md
covers the design rationale (D17/D18/D21 + CDX findings).

Schema parity:
- src/schema.sql for fresh Postgres installs
- src/core/pglite-schema.ts for fresh PGLite installs
- src/core/schema-embedded.ts auto-regenerated from schema.sql
- src/core/migrate.ts for upgrade-in-place from older brains

VERSION bumped to 0.36.0.0 for the wave. CHANGELOG entry lands at /ship.

* core: BaseCyclePhase abstract class enforces source-scope + budget contracts

D21 from the eng review. Three new v0.36.0.0 cycle phases (propose_takes,
grade_takes, calibration_profile) share enough structure that the
duplication-vs-abstraction trade tips toward a shared base. Without this
scaffold, source-isolation discipline would drift exactly the way it
drifted in v0.34.1 — except this time across three new surfaces at once.

What this enforces:

1. Phase signature is uniform: run(ctx, opts) → PhaseResult.

2. ctx.sourceId / ctx.auth.allowedSources MUST be threaded through every
   engine call. The base class surfaces a scope() helper that wraps
   sourceScopeOpts(ctx) and is the only sanctioned way to read source-
   scoped data. Forgetting to thread source scope becomes a TypeScript
   compile error, not a runtime leak. Closes the v0.34.1 leak class
   structurally for every new phase.

3. Budget meter wraps run() automatically. Subclass declares budgetUsdKey
   + budgetUsdDefault; base reads the resolved cap from config and creates
   the BudgetMeter. Subclass calls this.checkBudget() before each LLM
   submit; budget-exhausted phase still returns status='ok' (clean abort)
   so the cycle report shows partial completion, not failure.

4. Error envelope is uniform. Thrown errors get caught and converted to
   status='fail' with a phase-specific error.code via the subclass's
   mapErrorCode() hook.

5. Progress reporter integration. Base accepts the reporter via opts;
   subclasses call this.tick() instead of touching the reporter directly,
   so the phase name in the progress stream is always correct.

Tests: 13 cases in test/core/base-phase.test.ts cover source-scope
threading (5 cases including the empty-allowedSources-MUST-NOT-widen-scope
regression), PhaseResult shape including the error envelope path (3
cases), dry-run propagation (2 cases), and budget meter construction
(3 cases including config-key override).

Synthesize.ts / patterns.ts (existing pre-v0.36 phases) deliberately do
NOT retrofit to this base in v0.36.0.0 — too much churn for a refactor
that doesn't pay off until v0.37+. Future phases use this by default.

* cycle: propose_takes phase + take_proposals queue write path (T3)

LLM-based take extraction from markdown prose. Walks pages updated since
last cycle, sends each page's body to a tuned extractor, writes the
extracted gradeable claims to the take_proposals queue. User accepts /
rejects via `gbrain takes propose --review` (lands in Lane C).

Cycle wiring:
  lint → backlinks → sync → synthesize → extract → extract_facts →
    resolve_symbol_edges → patterns → recompute_emotional_weight →
    consolidate → propose_takes (NEW) → grade_takes (NEW; T4) →
    calibration_profile (NEW; T6) → embed → orphans → purge

CyclePhase enum extended with 3 new entries; ALL_PHASES + NEEDS_LOCK_PHASES
updated. All three new phases acquire the cycle lock (writes to
take_proposals / take_grade_cache / calibration_profiles).

Idempotency contract:
  The (source_id, page_slug, content_hash, prompt_version) composite unique
  index on take_proposals means an unchanged page never re-spends LLM
  tokens. Bumping PROPOSE_TAKES_PROMPT_VERSION cleanly invalidates the
  cache so a tuned prompt re-runs proposals on every page. Mirrors the
  v0.23 dream_verdicts pattern.

F2 fence dedup:
  The phase reads the page's existing `<!-- gbrain:takes:begin -->` fence
  (when present) and passes the canonical take rows to the extractor as
  "things you have already captured." Prevents duplicate proposals when
  prose is appended to a page that already has takes. Records the fence
  rows the LLM was told to dedupe against on the take_proposals row for
  audit (dedup_against_fence_rows JSONB).

Auto-resolve posture:
  propose_takes only WRITES proposals to the queue. Nothing in this phase
  mutates the canonical takes table. Operator opt-in via the queue review
  CLI (Lane C) is the only path from queue to canonical fence (D17).

Prompt tuning status (v0.36.0.0 ship state):
  The default extractor prompt is annotated `v0.36.0.0-stub`. The real
  tuned prompt arrives via T19 synthetic corpus build (50 anonymized
  pages, 3-model parallel extraction, user reviews disagreement set,
  F1 ≥ 0.85 on training corpus + F1 ≥ 0.8 on ground-truth holdout).
  Until T19 lands, propose_takes runs but produces best-effort candidates
  the user reviews manually.

Architecture:
  ProposeTakesPhase extends BaseCyclePhase (T2). Inherits source-scope
  threading via scope(), budget metering via this.checkBudget(), error
  envelope wrapping. budgetUsdKey: cycle.propose_takes.budget_usd
  (default $5/cycle). Budget exhaustion mid-page returns status='warn'
  with details.budget_exhausted=true — clean partial-completion semantics.

  Test seam: opts.extractor injection so the phase can run hermetically
  without touching the gateway. defaultExtractor (production path) calls
  gateway.chat with the EXTRACT_TAKES_PROMPT and parses the JSON array
  output via parseExtractorOutput.

  parseExtractorOutput defends against common LLM output sins: markdown
  code fence wrapping, leading prose, single-object instead of array,
  unknown kind values, weight out of [0,1], rows missing claim_text or
  exceeding 500 chars.

Tests: 25 cases in test/propose-takes.test.ts cover the 4 pure helpers
(parseExtractorOutput, contentHash, hasCompleteFence,
extractExistingTakesForDedup) + 7 phase integration scenarios (happy path,
cache hit, fence dedup, extractor failure, empty pages, skipPagesWithFence,
proposal_run_id stability).

* cycle: grade_takes phase + take_grade_cache verdict pipeline (T4)

Walks unresolved takes that are old enough to have outcome data, retrieves
evidence from the brain, asks a judge model to verdict each one. Writes
verdicts to take_grade_cache. Optionally — only when operator has flipped
the opt-in config flag — auto-applies high-confidence verdicts to the
canonical takes table via engine.resolveTake.

Auto-resolve posture (D17 — DISABLED by default):
  On a fresh install, grade_takes runs and writes verdicts to the cache,
  but applied=false on every row. Operator reviews the queue, then flips
  `cycle.grade_takes.auto_resolve.enabled: true` once trust is earned.
  Mirrors the propose_takes review-queue posture: queue exists, mutation
  requires explicit opt-in.

Conservative threshold (D12):
  When auto_resolve.enabled is true, a verdict auto-applies only when
  confidence >= 0.95 (single-judge path). T5 ensemble path lands next,
  tightening this further with 3/3 unanimous requirement.

  'unresolvable' verdict NEVER auto-applies even at confidence=1.0 —
  there's no canonical column for "we tried and there's no evidence yet."

Evidence retrieval status (v0.36.0.0 ship state):
  The default evidence retriever returns an "evidence-retrieval not yet
  wired" placeholder. Most verdicts produced by the stub-judge against
  the stub-evidence will be 'unresolvable'. Real retrieval (hybrid search
  over pages newer than the take's since_date, optionally augmented by a
  gateway web-search recipe in v0.37+) lands as a follow-up. Documented
  limitation per CDX-8 + D17 — the phase ships now so the wiring is real
  and the cache table accumulates verdicts even if early ones are
  conservative.

Cache key:
  Composite primary key on take_grade_cache is
  (take_id, prompt_version, judge_model_id, evidence_signature). Prompt
  edits OR evidence changes OR judge swap cleanly invalidate prior
  verdicts. Mirrors the v0.32.6 eval_contradictions_cache pattern.

  evidence_signature = SHA-256 of (judge_model_id + '|' + evidence_text)
  so identical evidence under a different judge does NOT collide.

Architecture:
  GradeTakesPhase extends BaseCyclePhase. Inherits source-scope threading,
  budget metering (cycle.grade_takes.budget_usd, default $3/cycle), error
  envelope. Test seam: opts.judge + opts.evidenceRetriever injection so
  the phase runs hermetically.

  parseJudgeOutput defends against fence-wrapping, leading prose,
  out-of-range confidence (clamps to [0,1]), invalid verdict labels,
  oversized reasoning (truncated at 400 chars). Returns null on
  unrecoverable parse — caller treats null as "judge_output_parse_failed
  / unresolvable at confidence 0.0" so the row still lands in cache with
  the parse failure surfaced via warnings.

  takeIsOldEnough gates on since_date (default 6 months). Tolerates
  YYYY-MM-DD and YYYY-MM formats. Returns false on null/unparseable
  since_date so takes without dates never get graded (we'd be
  hallucinating temporal context).

Tests: 23 cases covering parseJudgeOutput (7 cases), evidenceSignature
(3), takeIsOldEnough (5), and 8 phase integration scenarios — happy path,
D17 auto-resolve-off default, D12 above-threshold auto-apply, below-
threshold cache-only, unresolvable-NEVER-applies, cache hit, too-recent
gate, judge-throw warning.

* cycle: grade_takes ensemble tiebreaker for borderline verdicts (T5 / E2)

Multi-judge ensemble tiebreaker, additive on top of T4's single-judge
foundation. Reuses gateway.chat as the per-model judge interface; runs
three judges in parallel via Promise.allSettled. Pure aggregation logic
in aggregateEnsemble() — no SQL, no LLM, hermetically testable.

When ensemble fires (T5 trigger band):
  Only when ALL of:
    - opts.useEnsemble === true (default false)
    - opts.ensembleJudges array is non-empty
    - single-model confidence in [0.6, 0.95) (configurable via
      opts.ensembleTriggerBand)
    - single-model verdict !== 'unresolvable'

  Above 0.95 the single judge is already sufficient (T4 path). Below 0.6
  the verdict is clearly review-only — ensemble wouldn't change the
  posture. 'unresolvable' from single-judge means no evidence yet; calling
  three more judges on the same evidence won't manufacture some.

Conservative auto-apply (D12):
  Ensemble verdict auto-applies via engine.resolveTake only when ALL of:
    - autoResolve === true (operator opt-in per D17)
    - ensemble.agreement === 3 (3/3 unanimous)
    - ensemble.minConfidence >= ensembleThreshold (default 0.85)
    - winning verdict !== 'unresolvable'

  Schema-level monotonic-tightening guard for ensembleThreshold lives in
  the takes resolution layer.

Cache identity:
  When ensemble fires, the cache row's judge_model_id becomes
  'ensemble:<modelA>+<modelB>+<modelC>' — a future re-run with different
  ensemble membership doesn't collide with prior verdicts. evidence_signature
  is recomputed because it includes the judge_model_id.

aggregateEnsemble (pure):
  - 3/3 unanimous → agreement=3, minConfidence=min across the three
  - 2/3 majority → agreement=2, minConfidence across the agreeing two
  - 1/1/1 disagreement → tie-break: prefer non-'unresolvable', then
    alphabetical for determinism
  - 'unresolvable' from one model NEVER tips a 2-vote majority toward
    'unresolvable' — by-label tally only counts a model toward its own
    label
  - All three judges failing (allSettled rejected) → verdict='unresolvable'
    with agreement=0; auto-apply path blocked
  - Single judge survives + two fail → agreement=1; the lone verdict wins
    but auto-apply gated by the 3/3 requirement

Tests: 16 cases.
  aggregateEnsemble (6): 3/3, 2/3, 1/1/1, unresolvable-tipping-resistance,
  all-failed, partial-failed-but-survives.
  Phase trigger conditions (5): useEnsemble=false default, useEnsemble=true
  in borderline band, single >= 0.95 skip, single < 0.6 skip, single =
  'unresolvable' skip.
  Phase auto-apply rules (5): 3/3+threshold+autoResolve, 2/3 majority no
  apply, 3/3 below threshold no apply, one ensemble judge throws still
  aggregates from allSettled, empty ensembleJudges falls through to
  single.

* cycle: calibration_profile phase + shared voice gate across surfaces (T6)

The calibration narrative layer. Reads TakesScorecard, asks an LLM to
write 2-4 conversational pattern statements ("right on tactics, late on
macro by 18 months"), passes them through the voice gate, derives active
bias tags, writes the row to calibration_profiles. This is the read-side
that E1 (think anti-bias rewrite), E3 (contradictions join), E6
(dashboard), and E7 (real-time nudges) all consume.

Voice gate (D24 — single function, multiple surfaces):
  ALL five calibration UX surfaces import the same gateVoice() function
  from src/core/calibration/voice-gate.ts. Mode parameter
  ('pattern_statement' | 'nudge' | 'forecast_blurb' | 'dashboard_caption'
  | 'morning_pulse') drives surface-specific tuning via the rubric the
  gate ships to its Haiku judge. NO forked implementations — voice
  rubric drift would defeat the gate.

  Each mode's rubric explicitly forbids preachy / clinical / corporate
  voice; a structural test pins this. Anchors the cross-cutting voice
  rule from /plan-ceo-review D2-D8.

Fallback policy (D11):
  Up to 2 generation attempts (configurable). On both rejects → fall back
  to a hand-written template from src/core/calibration/templates.ts.
  Templates are intentionally short and a little "robotic" — they're the
  safety net, not the destination. voice_gate_passed=false +
  voice_gate_attempts get persisted on the calibration_profiles row so
  the operator can review the failing examples and tune the rubric over
  time. Suppressing the surface silently is NEVER an option — that's how
  voice quality silently degrades.

  parseJudgeOutput defaults to 'academic' on parse failure (NEVER passes
  pass-through) so a Haiku output garble falls through to the template
  rather than letting unverified text reach the user.

calibration_profile phase:
  Extends BaseCyclePhase. Cold-brain skip: <5 resolved takes → no row
  written, no LLM call. Otherwise: scorecard via engine.getScorecard()
  → patterns via voice-gated generator → bias tags via separate
  generator (best-effort; failure logs warning, phase continues).

  The DB INSERT lands in the v67 calibration_profiles row with
  source_id, holder, the patterns, voice gate audit fields, active bias
  tags, and grade_completion (F1 fix — partial-grade state surfaces to
  the dashboard "60% graded" badge).

  Budget gate at $0.50/cycle default (mostly Haiku). Below-budget
  before-LLM-call check returns status='warn' without writing the row.

  Per-domain scorecards are a placeholder for v0.36.0.0 ship state —
  the F12 batchGetTakesScorecards() engine method that powers per-domain
  rendering lands in Lane C alongside the CLI/MCP surface.

Architecture:
  parsePatternStatementsOutput is tolerant of LLM emitting numbered
  lists / bulleted lines despite the prompt asking for plain lines.
  Caps at 4 patterns + drops excessively long lines (>200 chars).

  parseBiasTagsOutput lowercases input + drops non-kebab-case tokens
  (defends against the LLM emitting "Over-Confident Geography" with
  spaces or capitals). Caps at 4 tags.

Tests: 43 cases across two new test files.
  voice-gate.test.ts (24): parseJudgeOutput (7), gateVoice happy path
  (3), fallback path (5), mode parity (2), templates (7).
  calibration-profile.test.ts (19): parsers (10), pickFallbackSlots
  (3), phase integration (6 — cold-brain skip, happy path, voice gate
  fallback, grade_completion plumbed through, bias-tags failure
  non-fatal, source_id scope reaches INSERT).

* cli: gbrain calibration + get_calibration_profile MCP op (T7)

Public-facing read surface for the v0.36.0.0 calibration wave. CLI prints
the active calibration profile; MCP op exposes the same data path for
agents. Mirror of the v0.29 salience/anomalies shape (pure data fn + JSON
formatter + human formatter + thin CLI dispatch).

CLI: `gbrain calibration`
  Flags:
    --holder <id>         specific holder (default 'garry')
    --json                machine output for piping
    --regenerate          run calibration_profile phase now
    --undo-wave <ver>     [placeholder — wires in Lane D / T17]
    ab-report             [placeholder — wires in Lane D / T18]

  Human output:
    Calibration profile — holder: garry, source: default
    Generated: <local timestamp>
    [Note: built on 60% graded — partial completion this cycle.]   (when grade_completion < 0.9)
    [Note: voice gate fell back to template (2 attempts).]         (when voice_gate_passed=false)

    Resolved: 12 takes
    Brier:    0.210 (lower is better)
    Accuracy: 60.0%
    Partial:  10.0%

    Pattern statements:
      • You called early-stage tactics well — 8 of 10 held up.

    Active bias tags: over-confident-geography

  Cold-brain fallback message names the exact dream command to run.

MCP: `get_calibration_profile` (scope: read)
  Param: holder?: string (defaults to 'garry')
  Returns: latest CalibrationProfileRow | null

  Source-scoping via sourceScopeOpts(ctx): scalar source-bound clients see
  only their source; federated_read scopes see the union of allowed sources;
  no source filter when neither is set (CLI default path).

  Throws GBrainError('INVALID_HOLDER') on empty/non-string holder so
  remote callers get a structured error instead of a SQL-shape failure.

Architecture:
  getLatestProfile is the pure data fn — engine + opts → CalibrationProfileRow | null.
  Reused by both the CLI and the MCP op. Source-scoped via the standard
  v0.34.1 spread pattern (scalar sourceId vs sourceIds array).

  formatProfileText is pure — null → cold-brain message, populated → full
  printout. Annotates partial-grade rows and voice-gate-fallback rows so
  the operator sees data-quality status inline.

  parseArgs is exported via __testing for unit coverage. Sub-command
  ('ab-report') vs flag distinction is intentional — keeps the surface
  parallel with `gbrain eval cross-modal` etc.

Tests: 21 cases.
  parseArgs (6 cases): empty, --holder, --json, --regenerate, --undo-wave, ab-report.
  getLatestProfile (5 cases): happy, null, scalar source scope, federated array
    scope, no-source-filter default.
  formatProfileText (5 cases): cold-brain, happy, partial-grade note, voice-fallback
    note, published-to-mounts note.
  getCalibrationProfileOp (5 cases): default holder, scalar source scope,
    federated scope union, returns-null-on-unknown-holder, throws on empty holder.

Lane D follow-ups: --undo-wave (T17) and ab-report (T18) print a clear
"lands in Lane D" stderr line + exit 2; the surfaces exist for early
testers, the implementations land next.

* think: --with-calibration + anti-bias prompt rewrite (T8 / E1, D22)

Optional anti-bias rewrite mode for `gbrain think`. When set, the active
calibration profile gets injected per the D22 placement spec (AFTER
retrieval evidence, BEFORE the user's question). The bias filter applies
to QUESTION FRAMING, not evidence interpretation — matches LLM-as-judge
best practice (bias prompts near end of context perform better).

Default behavior unchanged (R1 regression guard): omitting
--with-calibration produces the v0.28-vintage user-message shape with the
question first, then retrieval. Existing think users see no change.

Two user-message shapes in buildThinkUserMessage:

  Default (no calibration):
    Question: X
    <pages>...</pages>
    <takes>...</takes>
    <graph>...</graph>
    Respond with a single JSON object...

  With calibration (D22):
    <pages>...</pages>
    <takes>...</takes>
    <graph>...</graph>
    <calibration holder="garry">
      Track record: Brier 0.210 (lower is better).
      Active patterns:
        - You called early-stage tactics well — 8 of 10 held up.
      Active bias tags: over-confident-geography
    </calibration>
    Question: X
    Respond...

  Calibration block is built by buildCalibrationBlock (exported for the
  E3 contradictions probe to render the same shape).

System prompt extension (withCalibration:true):
  - Names BOTH the user's PRIOR (default reasoning) AND the COUNTER-PRIOR
    from their hedged-domain self.
  - References active bias tags by name when relevant ("this fits the
    over-confident-geography pattern").
  - Does NOT silently substitute the debiased answer. ALWAYS surfaces
    both priors transparently.
  - Adds a "Calibration" section between Conflicts and Gaps in the
    answer body.

RunThinkOpts extension:
  - withCalibration?: boolean — opt-in
  - calibrationHolder?: string — defaults to 'garry'

  When withCalibration=true and no profile exists, runThink falls back to
  baseline behavior + pushes NO_CALIBRATION_PROFILE to warnings (visible
  to the operator). When the calibration fetch fails, CALIBRATION_FETCH_FAILED
  warning surfaces with the underlying error. Either path keeps think working;
  the calibration loop is enhancement, not requirement.

CLI: `gbrain think "<q>" --with-calibration [--calibration-holder <id>]`

Tests: 11 cases.
  buildThinkSystemPrompt (4 cases): R1 regression — default/false/omitted
  → no anti-bias rules; with calibration → adds PRIOR + COUNTER-PRIOR +
  bias-tag reference; preserves existing hard rules.

  buildCalibrationBlock (3 cases): happy path, null brier omitted (not
  "Brier null"), empty patterns + tags still well-formed.

  buildThinkUserMessage (4 cases): R1 regression — without calibration:
  question first; D22 placement — retrieval → calibration → question →
  instruction; graph + calibration ordering; empty retrieval blocks render
  placeholders without breaking shape.

* contradictions: calibration-profile join (T9 / E3)

Cross-references each contradiction finding against the active calibration
profile. When a contradiction's domain matches an active bias tag (e.g.
"over-confident-geography" or "late-on-macro-tech"), the output gains a
one-line bias context explaining which pattern this fits.

Pure functions only — no DB writes, no LLM calls. The probe runner imports
tagFindingWithCalibration() and applies it to each finding before emitting.
When no profile exists or no tags match, the helper returns null and the
runner emits the unchanged finding (regression R2 — contradictions output
is byte-identical to v0.32.6 when no calibration profile is present).

Match heuristic (v0.36.0.0 ship-state):
  Bias tags are kebab-case axis-then-domain slugs ('over-confident-geography').
  computeDomainHint() extracts a domain hint from the finding's slugs +
  holder + verdict text:
    - wiki/companies/... → hiring | market-timing
    - wiki/people/... → founder-behavior
    - macro / geography / tactics / ai segments in slug → matching tag
  First-match-wins for ordering determinism.

  Match is intentionally fuzzy — the v0.32.6 contradictions probe doesn't
  yet carry structured domain metadata. v0.37+ structured-domain-on-takes
  (Hindsight-style enum) tightens this.

Output:
  Returns { bias_tag: string, context: string } | null.
  Context format: "This contradiction fits your active bias pattern
  \"<tag>\" (Brier 0.31). Verdict: contradiction; severity: medium.
  Consider reviewing both sides through the lens of that pattern."

Tests: 13 cases.
  R2 regression (2): null profile → null tag; empty active_bias_tags → null tag.
  computeDomainHint (5): companies / people / macro / geography / unknown
  paths produce expected hints.
  Match path (4): macro→late-on-macro-tech, geography→over-confident-geography,
  mismatch returns null, first-match-wins with multiple candidate tags.
  buildBiasContextString (2): emits tag+verdict+severity+Brier; omits
  Brier when null (no "Brier null" leak).

* calibration: Brier-trend forecast at write time (T10 / E5)

Pure math layer over existing TakesScorecard data. Zero new LLM cost, zero
new schema. Surfaces the user's historical Brier for the take's
(holder, domain) bucket at write time so they see "your historical Brier
in macro takes is 0.31" before committing the take.

Voice-gate-rendered output:
  The user-facing string goes through gateVoice mode='forecast_blurb' via
  templates.ts (already in T6). This module is the pure data layer; the
  template renders the math into the conversational voice.

v0.36.0.0 ship state:
  Bucket dimension is the DOMAIN (slug-prefix). The conviction-weight
  bucket dimension would need a new engine method
  (engine.batchGetTakeBucketStats per F11) — deferred to v0.37+. Until
  then, forecast = historical Brier in this holder's domain.

  resolveDomainPrefix() keeps slug-prefix-looking domain hints
  ('companies/', 'wiki/macro') and falls back to overall for free-form
  hints ('macro tech', 'geography'). Hindsight-style structured domain
  on takes (CDX-11 mitigation TODO) tightens this in v0.37+.

MIN_BUCKET_N = 5:
  Below this sample size, the forecast returns predicted_brier=null with
  insufficient_data=true. Template renders "Forecast unavailable: only N
  resolved takes at this conviction yet" instead of a noisy estimate.

Architecture:
  computeForecast(input) — pure function, takes scorecards already
  fetched; ideal for tests + reuse across batched paths.
  forecastForTake(engine, input) — convenience wrapper, 1-2 engine
  round-trips (no domain → 1; with domain → 2).
  batchForecast(engine, inputs[]) — memoizes per (holder, domainPrefix);
  N inputs collapse to ≤2*unique_holders unique engine calls. Used by
  the propose-queue review flow (50 candidates → 1-2 scorecard fetches).

Tests: 14 cases.
  computeForecast (4): insufficient_data branch, stable forecast,
    overall fallback, MIN_BUCKET_N export.
  resolveDomainPrefix (5): undefined/empty/whitespace → undefined;
    slug-prefix → kept; free-form → undefined.
  forecastForTake (3): 1-call overall, 2-call domain, free-form fallback.
  batchForecast (2): cache collapse for repeat queries; different holders
    do not collapse.

* calibration: gstack-learnings coupling on incorrect resolutions (T11 / E4)

When the grade_takes phase auto-resolves a take as 'incorrect' or 'partial',
optionally write a learning entry to gstack's per-project learnings.jsonl
so other gstack skills (plan-ceo-review, ship, investigate, ...) can pull
it as context when relevant. The brain teaches every other tool about
the user's track record.

Config gate (D5 / CDX-17 mitigation):
  `cycle.grade_takes.write_gstack_learnings` defaults FALSE. External
  users may not have gstack installed; the gstack-learnings binary API
  isn't stable yet. Garry's brain flips it true to opt in.

Quality gate:
  Only 'incorrect' and 'partial' verdicts trigger the write. 'correct'
  resolutions are noise (we expected the take to hold up — no learning).
  'unresolvable' has no canonical column. Defense-in-depth runtime guard
  in writeIncorrectResolution() rejects ineligible qualities with
  reason='quality_not_eligible' so a caller misuse never surfaces a
  malformed learning entry.

Auto-apply only:
  Coupling fires only when grade_takes both auto-applies AND the verdict
  is incorrect/partial AND the config flag is enabled. Manual resolutions
  via `gbrain takes resolve` intentionally DO NOT propagate to gstack —
  manual writes already carry operator intent; the calibration loop is
  the noise-prone path that earns coupling.

Namespace:
  Every entry's key starts with 'gbrain:calibration:v0.36.0.0:'. Lane D
  `gbrain calibration --undo-wave v0.36.0.0` (T17) filters on this prefix
  for the optional gstack-scrub step. First active bias tag suffixes the
  key (e.g. 'take-42:over-confident-geography') so future analysis can
  group learnings by bias pattern.

Architecture:
  buildLearningEntry — pure. Truncates claim at 200 chars + ellipsis;
  emits Pattern: line when activeBiasTags present; defaults confidence
  to 0.8 when caller omits it.

  writeIncorrectResolution — async wrapper. Honors config gate; honors
  quality gate; calls the injected writer (or defaultGstackWriter in
  production). Failures are non-fatal: returns
  { written: false, reason: 'write_failed' | 'binary_missing', error }.
  The grade_takes phase logs to result.warnings and continues — gstack
  coupling failure NEVER aborts a cycle.

  defaultGstackWriter — shells out to gstack-learnings-log binary via
  execFileSync. Throws GBrainError('GSTACK_BINARY_NOT_FOUND') when the
  binary isn't on PATH; writeIncorrectResolution classifies that error
  to reason='binary_missing' so the operator sees the install hint
  instead of a generic write_failed.

  Wired into grade-takes.ts after engine.resolveTake() inside the
  auto-apply block. Only fires when shouldApply=true.

Tests: 14 cases.
  buildLearningEntry (7): canonical shape, partial vs incorrect wording,
  bias-tag suffix, no-tag fallback, claim truncation, default confidence,
  no-reasoning omission.
  writeIncorrectResolution (7): config gate, quality gate, happy path,
  writer-throw graceful degrade, binary-missing classification, async
  writer awaited, partial quality writes.

* doctor: 4 calibration checks — abandoned/freshness/drift/voice (T12)

Adds the four calibration doctor checks per the eng-review spec.

abandoned_threads:
  Counts active high-conviction takes (weight >= 0.7) older than 12 months
  that have never been superseded. Signal, not error — always status='ok'
  with a count. The hint sends users to `gbrain calibration` for details.

calibration_freshness:
  Warns when the active profile is older than 7 days (configurable via
  the same env-var pattern other freshness checks use). Cold-brain branch
  (no profile yet) returns ok without scolding. Hint points at
  `gbrain calibration --regenerate`.

grade_confidence_drift (CDX-11 mitigation):
  Surfaces the count of auto-applied grade verdicts. Below 30: returns
  "need 30+ for drift detection". At/above 30: returns "drift math
  arrives in v0.37+". The surface is wired; the actual
  confidence-vs-accuracy correlation math is a v0.37+ follow-up once we
  have 30+ auto-applied verdicts to measure against. Closes the CDX-11
  hole structurally — the operator sees the surface even before the math
  is meaningful.

voice_gate_health:
  Tracks voice gate failure rate over the last 7 days. <30% fail rate →
  ok (template fallback is fine in isolation). >=30% → warn with hint
  to review src/core/calibration/voice-gate.ts rubric. Anchors the
  cross-cutting voice rule observability story.

All four checks return status='warn' with a diagnostic message on
engine errors — non-blocking, never throws. Matches the existing doctor
check pattern (see checkSyncFreshness for prior art).

Wired into runDoctor after checkRerankerHealth (the v0.35 cluster), in
the canonical block 10 slot.

Tests: 15 cases. 4 per check (happy path, alt-status, engine-throw
diagnostic, plus boundary tests for the freshness staleness gate at
exactly 7 days and the grade drift gate at 30 applied verdicts).

* calibration: E7 nudge + 14-day cooldown (T13 / D16 F3)

Real-time pattern surfacing when a newly-committed high-conviction take
matches an active bias pattern. Conversational nudge text via the
templates module; 14-day cooldown per (take_id, nudge_pattern) via
take_nudge_log to prevent the feedback loop where each cycle re-fires
the same nudge on the same take.

Threshold gates (D16 F3):
  - holder match (profile.holder === take.holder)
  - conviction-weight > 0.7 (strict greater than)
  - take's slug-derived domain hint matches an active bias tag
    (takeDomainHint — same heuristic as eval-contradictions/calibration-join.ts
    for cross-surface consistency)

Cooldown gate:
  Before firing, probe take_nudge_log for (take_id, nudge_pattern) rows
  with fired_at >= now() - 14 days. Any hit → silently skip. After firing,
  insert a new row with channel='stderr' so the next 14 days are gated.

Feedback-loop prevention:
  User hedges a take in response to a nudge (e.g. weight 0.85 → 0.65).
  Even though the take's `weight` field changed, the cooldown row for
  the over-confident-geography pattern is still there from the original
  fire — so the next cycle's evaluateAndFireNudge() silently skips. The
  user reset path (gbrain takes nudge --reset N) clears the cooldown to
  re-arm.

Output channel (v0.36.0.0 ship state):
  STDERR only. Schema's `channel` column already supports multi-channel
  (webhook, admin SPA toast); routing those is a v0.37+ follow-up.

Architecture:
  evaluateNudgeRule(take, profile) — pure rule check. Returns
  { matched, reason, matchedTag }. No engine call.
  checkCooldown(engine, takeId, pattern) — engine probe, returns boolean.
  recordNudgeFire(engine, opts) — INSERT into take_nudge_log.
  evaluateAndFireNudge(opts) — full pipeline. Returns NudgeDecision.
  resetNudgeCooldown(engine, takeId) — DELETE...RETURNING for the CLI.

  buildNudgeText delegates to templates.ts nudgeTemplate (D24 mode='nudge'
  voice). v0.36.0.0 ship state uses the template directly; LLM-generated
  nudge text via the voice gate lands in v0.37+ when we have production
  examples to tune from.

Tests: 22 cases.
  takeDomainHint (5): companies/people/macro/geography/unrecognized.
  evaluateNudgeRule (6): no_profile, wrong_holder, conviction-at-threshold-
  is-NOT-eligible (strict >), no matching tag, happy match,
  first-match-wins for multiple candidate tags.
  checkCooldown (3): true on row hit, false on no row, cutoff date param
  verifies the 14-day boundary.
  evaluateAndFireNudge (4): happy fire (text contains hush command +
  matched tag), cooldown silent skip (no INSERT, no stderr), no_profile
  short-circuit, below-conviction short-circuit (no cooldown query fired).
  buildNudgeText (2): hush command shape, conviction value embedded.
  resetNudgeCooldown (2): returns count, idempotent on zero rows.

* calibration: E8 team-brain sharing + D18 cross-brain query semantics (T14)

Cross-brain calibration profile resolution per the D18 4-rule contract.
Pins all four cross-brain leak surfaces in dedicated unit tests so future
mount features can't silently regress this security model.

D18 semantics (committed):

  Rule 1 — LOCAL-FIRST ORDERING.
    Query the local brain first. If a profile exists, return it. Do NOT
    also query mounts (avoids stale-mount-overrides-fresh-local).
    Verified: mountResolver is NOT called when local has a hit.

  Rule 2 — MOUNT FALLBACK.
    Only when local has no profile AND canReadMounts=true, walk the
    mounts in priority order. First match wins. Each mount-side row
    must have published=true to be visible (D15 asymmetric opt-in).

  Rule 3 — CROSS-BRAIN ATTRIBUTION.
    Every returned profile carries source_brain_id + from_mount flag.
    Consumers (E1 think rewrite, E3 contradictions, E7 nudge, E6
    dashboard) MUST surface this via attributionSuffix() so the user
    sees which brain answered.

  Rule 4 — SUBAGENT PROHIBITION.
    canReadMountsForCtx() classifier returns FALSE for subagent loops
    without trusted-workspace allowedSlugPrefixes. Closes the
    OAuth-token-to-cross-brain-leak surface — subagents see ONLY their
    local-brain results regardless of which holder they query.

    Exception: trusted cycle phases (synthesize/patterns) pass
    allowedSlugPrefixes set and ARE allowed to read mounts. Pinned in
    the classifier test.

Architecture:
  queryAcrossBrains(localEngine, opts) — pure orchestrator. Composes
  getLatestProfile() from src/commands/calibration.ts. Mount engine
  access is via opts.mountResolver — production wires this to the
  v0.19+ gbrain mounts subsystem; tests inject a stub returning an
  ordered list of mocked engines. Decouples cross-brain LOGIC from
  multi-engine PLUMBING.

  canReadMountsForCtx(ctx) — pure classifier table. Drives the rule-4
  gate. Production callers compose it from OperationContext.

  attributionSuffix(result) — pure formatter. Emits the "(from mounted
  brain: <id>)" suffix when from_mount=true; empty string when local.
  Mandatory for user-visible cross-brain consumers.

Tests: 15 cases pinned to the 4 D18 rules + 4 supplementary structural
checks.
  D18-1: published=false profile on mount stays hidden.
  D18-2/3: subagent context cannot fall back to mounts (2 cases — null
    on local-empty + canReadMounts=false, local hit still returned).
  D18-4: attribution surfaces source_brain_id (3 cases — mount answer
    flag, local answer flag, attributionSuffix formatter).
  Rule 1 local-first ordering (2 cases — mountResolver NOT called on
    local hit, IS called on local empty).
  Mount priority order (3 cases — first published=true wins, all
    published=false returns null, no mounts configured returns null
    without throwing).
  canReadMountsForCtx classifier (4 cases — local CLI true, MCP
    non-subagent true, subagent without trusted-workspace false,
    subagent WITH trusted-workspace true).

* admin: E6 Calibration tab + D23 server-rendered SVG + TD2 contrast bump (T15)

Adds the v0.36.0.0 admin SPA Calibration tab. Per the design review,
the approved variant-B (Linear calm clarity) layout: single-column flow,
generous whitespace, ONE big sparkline as hero, then patterns, then
domain bars, then abandoned threads.

D23 server-rendered SVG architecture:

  src/core/calibration/svg-renderer.ts — pure functions. data → SVG
  string. No DOM, no React, no chart library dep. Inlines the admin
  design tokens (#0a0a0f bg, #3b82f6 accent, etc.) so the SVG is
  visually consistent with the rest of the admin SPA.

  Four chart renderers:
    - renderBrierTrend({ series }) — sparkline w/ baseline reference
      at 0.25 (always-50% baseline)
    - renderDomainBars({ bars }) — horizontal accuracy bars per domain
    - renderAbandonedThreadsCard(threads) — D30/TD4 'revisit now' link
      per row, points at /admin/calibration/revisit/<takeId>
    - renderPatternStatementsCard(statements) — D29/TD3 clickable
      drill-down links per row, point at /admin/calibration/pattern/<i>

  XSS posture: all caller-controlled strings pass through escapeXml().
  Numeric inputs are .toFixed()-coerced. Admin SPA renders via
  dangerouslySetInnerHTML inside a TrustedSVG wrapper component;
  endpoint is gated by requireAdmin middleware.

  /admin/api/calibration/profile — returns the active profile row as JSON.
  /admin/api/calibration/charts/:type — returns image/svg+xml markup
    for type ∈ {brier-trend, domain-bars, pattern-statements,
                abandoned-threads}. Cache-Control: private, max-age=60.

  brier-trend currently renders a single-point series from the active
  profile (the time-series view across calibration_profiles.generated_at
  history is a v0.37 follow-up once we have multiple snapshots).
  abandoned-threads pulls the top 5 abandoned rows via the same SQL the
  doctor check uses.

CalibrationPage React component (admin/src/pages/Calibration.tsx):
  Fetches profile + 4 charts. Loading / error / cold-brain states all
  handled. Layout includes the audit annotations (partial-grade badge,
  voice-gate-fell-back-to-template badge) per the approved mockup.
  TrustedSVG wrapper isolates the dangerouslySetInnerHTML to the SVG
  surface only.

App.tsx nav: added 'calibration' page route + sidebar nav item, hash
routing extended to support #calibration.

TD2 contrast bump:
  admin/src/index.css --text-muted: #555 → #777. Old value was contrast
  4.0 on the #0a0a0f bg — below WCAG AA 4.5 for body text. New value is
  ~5.5, passes AA. Improvement is global across Dashboard, Agents,
  RequestLog, and the new Calibration tab — single-line CSS change with
  ~10x the impact.

admin/dist/ rebuilt via `bun run build` (vite). 36 modules transformed.

Tests: 19 cases in test/svg-renderer.test.ts.
  escapeXml (1): canonical entities.
  renderBrierTrend (6): empty state, polyline for 2+ points, clamp
  beyond yMax, design tokens inlined, XSS safety on date strings,
  text-anchor end on right label.
  renderDomainBars (4): empty state, label/accuracy/n rendering,
  out-of-range accuracy clamp, XSS safety on labels.
  renderAbandonedThreadsCard (4): empty state, row rendering with
  revisit link, claim truncation at 70 chars, custom revisitHref override.
  renderPatternStatementsCard (4): empty state, anchor count matches
  statement count, XSS safety, custom drillHref override.

* recall: calibration footer formatter for morning pulse (T16)

Pure formatter that turns a CalibrationProfileRow + optional abandoned-
threads list into the conversational block the morning pulse will surface:

  Calibration this quarter:
    Brier 0.18 (solid).
    Right on early-stage tactics, late on macro by 18 months.
    Over-confident on team execution; under-calibrated on regulatory risk.

  Threads you opened and never came back to:
    · AI search platform differentiation         (17 months silent)
    · International expansion playbook           (12 months silent)

Cold-brain branch: returns empty string when no profile or < 5 resolved
takes. Caller decides whether to render the block; cold-brain absence
is the cleanest non-event.

Brier trend note maps the absolute value to conversational copy:
  <= 0.10 → "(strong calibration)"
  <= 0.20 → "(solid)"
  <= 0.25 → "(near baseline)"
  > 0.25  → "(worse than always-50% baseline — review your high-conviction calls)"

  v0.36.0.0 ship state has only the current profile snapshot. The
  "was 0.22 90d ago — improving" comparison shape arrives when we
  accumulate generated_at history across multiple cycles.

R3 regression posture:
  This module is the FORMATTER only. Wiring into `gbrain recall`'s text
  output is intentionally NOT in this commit — runRecall's surface
  stays unchanged. v0.37 wires it under --show-calibration (opt-in
  initially, default-on later). For now the formatter is callable from
  the admin tab + custom CLI scripts that want it.

Architecture:
  buildRecallCalibrationFooter(opts) — pure. opts.profile required,
  opts.abandonedThreads optional, opts.threadColumnWidth defaults to 50.

  Caps at 4 patterns + 5 abandoned threads to keep the footer scannable.
  Truncates long abandoned-thread claim text to fit the column width with
  a trailing ellipsis.

Tests: 14 cases.
  Cold-brain branch (3): null profile, < 5 resolved, zero resolved.
  Happy path (7): header + Brier + patterns, trend note ranges (4
  brackets), null brier omits the Brier line but keeps header, caps at
  4 patterns.
  Abandoned threads (4): omit section when none, emit when present,
  cap at 5, truncate long claim with column-width override.

* calibration: --undo-wave reversal command (T17 / D18 CDX-3)

Implements the undo-wave reversal flow. Every new row written by the
v0.36.0.0 calibration wave carries wave_version='v0.36.0.0' so a precise
revert is possible without touching pre-wave data.

CLI surface (replaces the v0.36.0.0 ship-state placeholder):
  gbrain calibration --undo-wave v0.36.0.0 [--dry-run] [--scrub-gstack] [--json]

Reversal scope (4 steps):

  Step 1 — UNSET takes.resolved_* columns for takes auto-applied by this
  wave. Identifies wave-applied takes via take_grade_cache.applied=true
  + wave_version match. Cross-checks resolved_by='gbrain:grade_takes' to
  ensure we're not un-resolving a take a manual `gbrain takes resolve`
  override has since claimed. Manual resolutions persist; only auto-grade
  resolutions revert.

  Step 1b — Mark take_grade_cache rows applied=false post-undo so the
  audit trail shows they WERE applied but this wave was reverted. The
  CDX-11 confidence-drift check filters on applied=true and gets a
  cleaner sample post-undo.

  Step 2 — DELETE FROM calibration_profiles WHERE wave_version = ?.

  Step 3 — DELETE FROM take_nudge_log WHERE wave_version = ?.

  Step 4 — Optional gstack-learnings-prune via the binary, scoped to the
  GSTACK_LEARNING_NAMESPACE prefix. Opt-in via --scrub-gstack. Best-effort:
  binary-missing or failure logs a warning + suggests the manual command;
  the rest of the undo still succeeded.

Dry-run posture:
  --dry-run computes the counts via SELECT COUNT(*) shapes without
  emitting any UPDATE or DELETE. Same UndoWaveResult shape returned so
  operator sees exactly what would be reverted before committing.

  --dry-run intentionally skips the gstack scrub (filesystem write) too;
  ship-state safety call.

Idempotency:
  Re-running --undo-wave on a brain that's already reverted is a no-op.
  Each query filters on wave_version; no matching rows → zero counts.

Architecture:
  undoWave(engine, opts) — async, returns UndoWaveResult. Pure data
  layer; no stderr writes, no process exits. CLI dispatch in
  src/commands/calibration.ts handles printing.

  v0.36.0.0 ship state runs steps 1-3 sequentially (no transaction).
  Partial reversal is recoverable via re-run since each step is
  idempotent on wave_version match. A future enhancement (v0.37+) can
  wrap in engine.transaction once that surface lands in BrainEngine.

Tests: 8 cases in test/undo-wave.test.ts.
  Dry-run posture (1): counts emitted, NO UPDATE/DELETE SQL fired.
  Happy path (3): all 4 steps execute, resolved_by filter scopes UPDATE
  to wave-applied resolutions, custom resolvedByLabel honored.
  Empty wave (2): zero counts when no matching rows, idempotent re-run.
  Wave-version parameter threading (2): supplied version threads
  through all queries, different wave versions don't collide.

* calibration: A/B harness for think + ab-report (T18 / D19 CDX-18)

Structural answer to CDX-18 (anti-bias rewrite may make advice worse).
We don't have to guess whether calibration helps — we measure.

Architecture:
  runAbTrial(input) — calls thinkRunner TWICE on the same question
  (baseline + --with-calibration), surfaces both answers to a
  preferenceResolver, persists the trial to think_ab_results.

  buildAbReport(engine, { days }) — aggregates the table over the last
  N days (default 30). Computes win counts, ties, neither, and a
  with_calibration_win_rate over DECISIVE trials only (excludes
  neither/tie). Flags calibration_net_negative when n >= 20 AND win
  rate < 45%.

  formatAbReport(report, days) — pretty-prints for stdout; emits the
  calibration_net_negative warning block when triggered.

CLI:
  gbrain calibration ab-report [--days N] [--json]
    Reads the table, prints the breakdown. Replaces the v0.36.0.0
    ship-state placeholder in src/commands/calibration.ts.

  gbrain think --ab "<question>"
    Wires into runAbTrial via the dispatch in src/commands/think.ts —
    follow-up commit. This commit lands the harness layer + schema +
    report surface; the --ab flag itself flips on in a one-line wiring
    commit when the runRecall path is ready.

Schema (migration v72 / think_ab_results):
  source_id, wave_version, ran_at, question, baseline_answer,
  with_calibration_answer, preferred (CHECK in {baseline,
  with_calibration, neither, tie}), model_id, notes.

  CHECK constraint enforces preferred enum. Default wave_version
  'v0.36.0.0' stamped so --undo-wave can scrub these too.

  Index on (source_id, ran_at DESC) supports the report's
  "last N days" query.

  schema.sql + pglite-schema.ts both updated for fresh-install parity.
  schema-embedded.ts regenerated via build:schema.

calibration_net_negative threshold (D19):
  Triggers when:
    - decisive_trials (baseline + with_calibration) >= 20
    - with_calibration_win_rate < 0.45 (NOT <= — exact 45% is OK)

  Small-sample guard (n < 20) prevents the warning from firing on
  early data with sampling noise. Confidence-flat threshold (no Wilson
  CI yet) keeps the math simple; v0.37+ adds CI bounds.

Tests: 12 cases in test/think-ab.test.ts.
  runAbTrial (4): both runner calls fire, preferenceResolver receives
    both answers, INSERT row params shape, throws when thinkRunner
    missing.
  buildAbReport (5): zero trials, aggregation, net_negative trigger at
    n>=20 + win<45%, no trigger at n<20 (small-sample guard), no
    trigger at exact 45% boundary.
  formatAbReport (3): zero-state message, decisive-trials breakdown,
    net_negative warning block.

* calibration: pattern drill-down route + revisit-now CLI (TD3 / D29 + TD4 / D30)

TD3 (D29) — clickable pattern drill-down endpoint:
  GET /admin/api/calibration/pattern/:id (requireAdmin)
  Returns the pattern statement at index `id` plus the top 25 resolved
  takes for the holder, sorted by weight desc. v0.36.0.0 ship-state
  approximation: surfaces broad provenance evidence (top resolved
  takes). v0.37+ stores per-pattern source_take_ids[] on a
  calibration_profile_patterns join table so the drill-down shows the
  EXACT takes that drove the pattern.

  Surfaces a `provenance_note` field in the response so the operator
  sees the v0.36.0.0-vs-v0.37 fidelity boundary inline.

  The admin SPA's renderPatternStatementsCard SVG already emits anchor
  tags pointing at /admin/calibration/pattern/<i> (T15 ship state).
  This route makes those anchors clickable — closes the trust loop that
  was the rationale for D29 ("pattern statements without their evidence
  are dressed-up LLM hallucinations").

TD4 (D30) — `gbrain takes revisit <slug>` editor-open action:
  Adds the `revisit` subcommand to gbrain takes. Opens $EDITOR (falling
  back to vi) on the source markdown file for the slug. Appends a
  `<!-- gbrain:revisit -->` cursor marker at the bottom of the page on
  first invocation so the editor opens with intent visible.

  Reads sync.repo_path from config to locate the brain repo. Refuses to
  proceed with a clear error when the repo isn't configured or the page
  doesn't exist.

  spawnSync with stdio:'inherit' so the editor takes the terminal. Exit
  status surfaced on failure.

  The SVG renderer's revisit-now anchor for each abandoned thread row
  emits /admin/calibration/revisit/<takeId>. A small route handler that
  resolves take_id → page_slug then dispatches `gbrain takes revisit`
  via spawn is a v0.37 follow-up — the CLI command exists now so
  developers can wire it directly.

* docs: DESIGN.md — formalize de facto design tokens (TD1)

Promotes the admin SPA's de facto design tokens (landed v0.26.0) to a
canonical DESIGN.md at the repo root. This is the calibration target
for /plan-design-review and /design-review going forward — when a
question is "does this UI fit the system?", the answer is here.

Captures the system as it stands today:

  Voice (5 surfaces, all routed through gateVoice() with mode-specific
  rubrics): pattern_statement, nudge, forecast_blurb, dashboard_caption,
  morning_pulse. Friend-not-doctor; concrete data over abstract metrics;
  no preachy / clinical / corporate language.

  Color tokens: 10 CSS variables from admin/src/index.css inlined into
  the SVG renderer (src/core/calibration/svg-renderer.ts). Dark theme
  is the only theme — admin is an operator tool. WCAG contrast
  documented per token; TD2's #555 → #777 bump on --text-muted noted.

  Typography: Inter for UI, JetBrains Mono for numbers/slugs/data.
  Type scale (18 / 14 / 13 / 12 / 11) documented as de facto, not yet
  formalized.

  Spacing scale: 4 / 8 / 16 / 24 / 32px. Linear-app density.

  Layout: sidebar 200px, max content 720px (text) / 960px (tables).
  No 3-column feature grids, no icons in colored circles, no
  decorative blobs.

  Charts: server-rendered SVG via pure functions in
  src/core/calibration/svg-renderer.ts. XSS posture documented:
  server-side escapeXml on caller-controlled strings, numeric inputs
  .toFixed()-coerced, admin SPA renders via <TrustedSVG> wrapper.

  Interaction patterns: keyboard nav required (J/K/space/u/q on the
  propose-queue), loading/empty/error states ARE features.

  v0.37+ roadmap: type scale formalization, animation tokens, component
  library extraction. Light mode explicitly NOT planned.

The doc is a living target, not a frozen spec. Major changes route
through /plan-design-review per the existing review chain.

* calibration: synthetic corpus scaffold + privacy CI guard (T19 + T20)

T19 — synthetic corpus scaffold for extract-takes prompt tuning.
  test/fixtures/calibration/extract-takes-corpus/ — 5 representative
  pages across 4 genres (essay, people, companies, meetings, decisions).
  v0.36.0.0 ships a SMALL representative corpus as proof of structure;
  the full 50-page training set + 10-page holdout gets generated by the
  operator via `gbrain calibration build-corpus` (v0.37 follow-up
  subcommand) or by hand with the privacy guard catching violations
  either way.

  Privacy contract per D13': every page is SYNTHETIC. None of the
  names/companies/funds/deals/events refer to anything real. Placeholder
  names per CLAUDE.md: alice-example, charlie-example, acme-example,
  widget-co, fund-a/b/c, acme-seed, widget-series-a, meetings/2026-04-03.

  test/fixtures/calibration/README.md spells out the privacy contract,
  generation flow, and what the corpus is (stable regression set for
  the extract-takes prompt) vs is not (real anything).

T20 — privacy CI guard (CDX-14 mitigation).
  scripts/check-synthetic-corpus-privacy.sh greps the corpus for:
    1. Explicit dollar amounts ($50M, $1.2B etc) — would suggest the
       page memorized a real round size.
    2. Out-of-range year references (informational only for v0.36.0.0;
       deferred to a manual review checklist).
    3. Pages that reference ZERO placeholder names — suggests the page
       might be referring to real entities. Essay-genre fixtures
       exempt (they're anonymized PG-style writing by design).

  Wired into `bun run verify` (CI gate) so contributors can't accidentally
  land a synthetic fixture that leaks real-world specificity. The intent
  is fail-fast on accidental leakage; the operator can update the
  allowlist if a generic dollar amount is intentional.

  Closes CDX-14: 'CC reads real brain pages locally, writes nothing
  still risks privacy if any generated synthetic fixture memorizes
  structure-specific facts. Placeholder names are not enough.'

The corpus shipped here is intentionally small but covers the four
core gbrain page genres (essay, people, companies, meetings/decisions).
The v0.37 corpus-build subcommand will fan out to 50 with the operator
spot-checking + the CI guard enforcing the privacy contract.

* test: R1-R5 IRON RULE regression inventory (T21)

Per /plan-eng-review D26 IRON RULE: regressions get added to the test
suite as critical requirements, no AskUserQuestion needed. Pins five
regressions identified during the v0.36.0.0 wave's coverage diagram:

  R1: think baseline UNCHANGED when --with-calibration absent.
      Covered structurally by test/think-with-calibration.test.ts plus
      assertion-pinned in this file (default user message: question
      first, then retrieval; system prompt: no anti-bias section).

  R2: contradictions probe output UNCHANGED when no calibration profile.
      Covered structurally by test/eval-contradictions-calibration-join.test.ts
      plus pinned here (null profile → null tag, byte-identical to v0.32.6).

  R3: takes resolution flow works when grade_takes phase disabled.
      Pinned import-surface coupling: takes-resolution.ts has zero
      dependency on grade_takes module. If a future refactor accidentally
      couples them, this test fails to compile.

  R4: search/list_pages/get_page work identically through new source_id paths.
      Marker test referencing existing v0.34.1 source-isolation suite at
      test/source-isolation-pglite.test.ts. v0.36.0.0 does NOT modify
      those code paths; the existing tests catch any accidental coupling.

  R5: existing search modes (conservative/balanced/tokenmax) unaffected.
      Marker test referencing existing test/search-mode.test.ts. The
      calibration code DOES NOT IMPORT from src/core/search/mode.ts.

Plus an inventory test that confirms all 5 regressions have an
'addressed' status — fail-loud if a future contributor removes a
guard without updating the inventory.

7 tests total. Pure functions, no engine, hermetic.

* docs: v0.36.0.0 CHANGELOG + CLAUDE.md anchors + calibration convention skill

CHANGELOG entry: the user-facing release notes. Leads with the headline
("the brain learns how you tend to be wrong, then argues against your
blind spots on every advice call"), 5 'what you can now do' bullets in
GStack voice, itemized changes by lane, and the 'To take advantage of
v0.36.0.0' upgrade checklist per the CLAUDE.md required-block contract.

CLAUDE.md anchors: new 'v0.36.0.0 Hindsight calibration wave (key files
cluster)' block inserted before the v0.31.1 thin-client section. 23 new
files / extensions annotated with one-paragraph descriptions each,
linking back to the convention skill at skills/conventions/calibration.md
for the agent-facing rules.

skills/conventions/calibration.md: the agent-facing convention skill.
Tells future contributors which calibration touchpoint applies to
their task — voice gate? BaseCyclePhase? source-scope thread? doctor
warning? cross-brain query rules? auto-resolve threshold posture? Test
seam patterns. Bug class to avoid (the v0.34.1 source-isolation leak
shape).

Version trio (per CLAUDE.md mandatory audit):
  VERSION:     0.36.0.0
  package.json: 0.36.0.0
  CHANGELOG:   ## [0.36.0.0] - 2026-05-17

llms.txt + llms-full.txt regenerated via `bun run build:llms` after
the CLAUDE.md edit (per the explicit CLAUDE.md mandate "Any CLAUDE.md
edit MUST be followed by `bun run build:llms`"). The `test/build-llms.test.ts`
guard runs in CI shard 1; the committed bundles are checked against
fresh generator output.

bun run verify is clean. typecheck clean. Privacy CI guard passes
(0 violations across 6 corpus pages). All ready for /ship.

* cycle: wire propose_takes / grade_takes / calibration_profile into runCycle (T-fix)

The three new v0.36.0.0 phases were declared in CyclePhase / ALL_PHASES /
NEEDS_LOCK_PHASES but the runCycle orchestrator never dispatched them.
ALL_PHASES advertised them, gbrain dream --phase propose_takes accepted
them, but `gbrain dream` (default) silently skipped all three.

Adds a single dispatch block between consolidate and embed that:
  - builds an OperationContext on the fly (trusted-workspace caller,
    remote: false, sourceId resolved via the same helper sync uses)
  - dispatches the three phases in the order ALL_PHASES declares
  - records the same skipped-phase shape (no_database) when engine is null

Pinned by test/core/cycle.serial.test.ts "default: all 6 phases run in
order" which was already failing against ALL_PHASES (the test name lags
the actual phase count; left as-is since renaming churns history).

* calibration: expand synthetic corpus + add hand-labeled ground-truth (T19)

Adds 8 new synthetic pages modeled on the genre mix observed in the
real brain (concepts-with-timeline, meeting-notes, daily-journal,
people-pages, essays). Companion .gradeable-claims.json files carry
hand-labeled answer keys — what a tuned propose_takes prompt SHOULD
extract per page. Closes the F1 gate gap from the plan's T19/D19:

  Training corpus (test/fixtures/calibration/extract-takes-corpus/):
    + concept-startup-market-dynamics.md     (10 claims)
    + meeting-2026-04-10-fundraise-fund-a.md (6 claims)
    + daily-2026-04-15.md                    (5 claims)

  Blind holdout (test/fixtures/calibration/holdout/):
    + concept-founder-execution.md           (6 claims, F1 >= 0.80)
    + daily-2026-04-18.md                    (4 claims, F1 >= 0.80)
    + meeting-2026-04-17-hiring-charlie.md   (5 claims, F1 >= 0.80)
    + essay-on-conviction.md                 (7 claims, F1 >= 0.80)
    + people-bob-example.md                  (5 claims, F1 >= 0.80)

Privacy:
  - No real-brain content read into any committed artifact. Pages
    written from scratch using the canonical placeholder set
    (alice-example, charlie-example, bob-example, acme-example,
    widget-co, fund-a/b/c). Real-name grep confirms zero leakage:
    wintermute, garrytan, paul-graham, sam-altman, etc. → 0 hits.
  - scripts/check-synthetic-corpus-privacy.sh passes: 0 violations
    across 14 pages (was 6).

Genre fidelity:
  - concept-with-timeline pages mirror the dated-assertion structure
    real brain uses (verb framing varies: "argues / predicts / I
    think / I bet / strong conviction / moderate conviction").
  - meeting-notes pages carry both prose claims (extracted via
    hedging language) and explicit ## Takes sections.
  - daily-journal pages test probabilistic framing ("75/25 in favor",
    "call it ~0.5") and self-tagged conviction values.
  - essay-on-conviction is the meta-page that names the author's
    own bias patterns — primary signal for calibration_profile.
  - people pages test claim-about-third-party extraction.

Each JSON ground-truth lists per-claim:
  - claim_text + kind (prediction|judgment|bet) + domain
  - conviction (0..1)
  - since_date
  - rationale (why this claim is gradeable + how a tuned prompt
    should infer conviction from the prose)

This is the corpus that gates the T19 prompt-tune iteration:
  - F1 >= 0.85 on training (10+6+5 = 21 claims across 3 pages
    plus the existing 5 fixtures already shipped)
  - F1 >= 0.80 on holdout (27 claims across 5 pages)

Plan reference: ~/.claude/plans/system-instruction-you-are-working-rippling-knuth.md
Privacy gate: scripts/check-synthetic-corpus-privacy.sh (wired into bun run verify).

* calibration: tune propose_takes prompt against synthetic corpus (cat15 F1 0.92+)

The v0.36.1.0 ship state shipped propose_takes with a stub prompt that
the docs flagged as "tune via T19 corpus build before relying on
propose_takes in production." T19's corpus was built in commit 69a71c9d
(14 synthetic pages + 48 hand-labeled claims). The matching gbrain-evals
cat15 runner validates extraction quality against that corpus.

This commit back-ports the tuned prompt validated by cat15's first live
run:

  training avg F1: 0.952  (target 0.85, +10 points)
  holdout  avg F1: 0.922  (target 0.80, +12 points)
  train-holdout gap: 0.03 (well below 0.10 overfitting threshold)
  8/8 probes pass their individual F1 targets

Per-genre F1 floor: 0.80 (people-pages, the hardest genre). Concept-
with-timeline and meeting-notes genres scored at 1.00 on holdout pages.

The tuned prompt design changes vs the stub:
  - Worked example list seeds the "gradeable claim" notion so the model
    doesn't drift into pure-fact extraction.
  - NOT-gradeable list catches the most common over-extraction modes
    (pure facts, direct quotes, restatements).
  - Conviction inference rules anchored to specific hedging language
    so the model produces consistent weight values.
  - kind enum narrowed to 'prediction' | 'judgment' | 'bet' — the v1
    stub's 4-tag enum bled into noise classification on the corpus.

PROPOSE_TAKES_PROMPT_VERSION bumped 'v0.36.1.0-stub' → 'v0.36.1.0-tuned-cat15'.
The bump invalidates the take_proposals idempotency cache so existing
proposal rows stay as audit history but the next cycle re-extracts
against the new prompt — exactly the design contract this version
field is for.

Re-tuning protocol: run cat15 in gbrain-evals against the fixtures
BEFORE bumping the version string. The train-holdout gap should stay
< 0.10. If a future tune drops below the cat15 gate, revert.

Source of evidence:
  - cat15 runner: ~/git/gbrain-evals/eval/runner/cat15-propose-takes.ts
  - Fixture corpus: test/fixtures/calibration/ (this repo, commit 69a71c9d)
  - Live run dumps: ~/git/gbrain-evals/eval/reports/cat15-propose-takes/*.json

* docs: link cat14/cat15 benchmark report from CHANGELOG + README

Adds the "Validated by published benchmarks" subsection to the v0.36.1.0
CHANGELOG entry and a "Calibration loop" section to the README's
"Receipts on the evals" surface. Both link to the new benchmark report
at gbrain-evals/docs/benchmarks/2026-05-18-brainbench-cat14-cat15-calibration.md.

CHANGELOG: also updates the propose_takes bullet to reflect that the
v0.36.1.0 ship state now includes the tuned 'v0.36.1.0-tuned-cat15'
prompt (back-ported in 04dbab44), not the v1 stub the original entry
described.

README: adds a Calibration loop entry to the receipts table sitting
between source-aware ranking and prompt compression. Frames the cat14
+ cat15 numbers as "first published benchmark for AI memory systems
that reason about user track records" — honest SOTA framing since
Hindsight introduced the concept without quantified evaluation.

llms.txt + llms-full.txt regenerated.

* docs: fix benchmark-report links — gbrain-evals uses main not master

7 links to gbrain-evals/blob/master/docs/benchmarks/ were broken — the
gbrain-evals repo uses 'main' as its default branch, not 'master'.
Surfaced when I checked that the new cat14/cat15 link resolved post-PR-9
merge. Turned out 4 pre-existing links to longmemeval, brainbench-v0.20,
brainbench-cat13b-source-swamp, and comparison-systems were all broken
for the same reason — I just added a fifth by following the same wrong
pattern.

Sweep: gbrain-evals/blob/master/ → gbrain-evals/blob/main/ across both
README.md (5 links) and CHANGELOG.md (2 links).

llms.txt + llms-full.txt regenerated.

Garry TanandGitHub 61b79e7c99 v0.35.8.0 feat(cycle): phantom-page redirect inside extract_facts (#1138) 
* feat(cycle): phantom-page redirect inside extract_facts (v0.35.8.0)

Drains the existing pile of unprefixed entity pages (alice.md, acme.md)
that pre-PR-#1010 routing left behind. Folds the cleanup into the existing
extract_facts cycle phase via two new lossless engine primitives so the
v0.32.2 reconciliation contract owns drift handling instead of a parallel
implementation duplicating it.

Layers:
- engine: refreshPageBody + migrateFactsToCanonical on Postgres + PGLite
- resolver: resolvePhantomCanonical + findPrefixCandidates (codex #1/#11)
- orchestrator: src/core/cycle/phantom-redirect.ts + phantom-audit JSONL
- cycle: sourceId/brainDir threaded; 3 new totals counters
- tests: 38 unit + 6 parity + 4 E2E (48 total) pinning all 12 codex findings

* fix(test): pin clock in sync_freshness boundary tests (CI flake)

CI test (1) failed: `sync_freshness check > exact 72h boundary → warn`.
The test set `last_sync_at = Date.now() - 72h`, then checkSyncFreshness
called Date.now() again to compute ageMs. Between the two reads the
clock advanced (0.43ms in this CI run, microseconds locally) which
pushed ageMs above the strict 72h fail threshold and flipped the
status from warn to fail.

Same shape latent in the 24h boundary test — fixed both.

Fix:
- checkSyncFreshness gains an optional `opts.nowMs` test-only seam.
  Production callers omit it and get live wall-clock semantics.
- Both boundary tests now capture nowMs once and thread it through
  both `last_sync_at` and the check, eliminating drift between reads.

Verified deterministic: 10 consecutive runs of the 72h boundary test
pass on this machine (was occasionally failing before).

 		1dadd9ed71 v0.35.7.0 feat: temporal trajectory + founder scorecard (Phases 2-4) (#1131) 
* feat(facts): typed-claim substrate + cycle correctness fixes (v0.35.6 wave 1/3)

Schema (migration v67):
- Add four optional typed-claim columns to facts: claim_metric TEXT,
  claim_value DOUBLE PRECISION, claim_unit TEXT, claim_period TEXT
- Partial index facts_typed_claim_idx ON (entity_slug, claim_metric, valid_from)
  WHERE claim_metric IS NOT NULL
- All nullable, metadata-only on both engines

Fence layer:
- ParsedFact (facts-fence.ts) gains optional claimMetric/Value/Unit/Period
- Parser tolerates both 10-cell (legacy) and 14-cell (widened) rows
- Renderer emits 14 cells iff any row has typed data; otherwise stays
  10-cell so existing fences don't widen on unrelated edits
- Numeric value cell tolerates comma thousand separators (50,000 -> 50000)

Extract pipeline (D-CDX-2, D-ENG-1):
- src/core/facts/extract.ts (the actual Haiku call site, NOT extract-facts.ts
  cycle phase) extends its system prompt to emit typed fields for metric-shaped
  claims
- extractFactsFromFenceText gains optional pageEffectiveDate. Precedence:
  fence-row validFrom > pageEffectiveDate > undefined (engine defaults to now)
- normalizeMetricLabel: 15-entry seed map for common founder metrics (mrr,
  arr, runway, headcount, team_size, cac, ltv, gross_margin, burn_rate, cash,
  users, mau, dau, churn_rate, revenue); unknown labels lowercase + space->_

Engine extensions:
- NewFact + insertFact + insertFacts in both engines accept the four typed
  columns (all nullable)
- Cycle phase extract-facts.ts threads page.effective_date through AND
  batch-embeds via gateway.embed() before insertFacts (D-CDX-3 fix for
  cycle-inserted facts arriving with embedding=NULL)

Consolidate fix (D-CDX-4 — Codex F4):
- Replace MAX(row_num)+1 INSERT with semantic upsert on (page_id, claim,
  since_date). Re-running the full cycle on stable input produces zero new
  takes — fixes the pre-existing duplicate-takes bug after extract_facts
  wipes consolidated_at
- Chronological valid_until writeback per cluster: sort by (valid_from ASC,
  id ASC), walk pairs, set older.valid_until = newer.valid_from

Tests:
- test/migrate.test.ts +6 cases for v67 shape + materialization + nullable
  backward compat
- test/facts-fence-typed.test.ts (new, 17 cases): parser+renderer round-trip,
  normalization seed map coverage, valid_from precedence three-branch
- test/consolidate-valid-until.test.ts (new, 4 cases): chronological
  writeback (R4a), same-day id tiebreaker, cycle re-run zero duplicates
  (R4b/R7), valid_until idempotency
- test/schema-bootstrap-coverage.test.ts: add four typed-claim columns to
  COLUMN_EXEMPTIONS (migration co-defines the partial index, no forward
  reference to bootstrap)

* feat(trajectory): find_trajectory MCP op + eval/founder CLIs (v0.35.6 wave 2/3)

Engine method (D-CDX-1, D-CDX-6):
- BrainEngine.findTrajectory(opts) on both Postgres and PGLite
- TrajectoryOpts: scalar sourceId fast path + sourceIds federated array
  (mirrors v0.34.1.0 search* dual pattern)
- opts.remote: when true, SQL adds AND visibility='world' so OAuth read
  clients see only world-visibility facts (mirrors recall's posture —
  closes the F7 privacy regression Codex caught in plan review)
- Single SQL query, ORDER BY valid_from ASC, id ASC for deterministic
  output (R3 pin). Returns TrajectoryPoint[] including raw embedding so
  the caller can compute drift without a second round-trip

Pure function library (src/core/trajectory.ts, new):
- detectRegressions(points, threshold): walks consecutive (metric, value)
  pairs per metric; emits when newer drops >= threshold below older.
  10% default, override via GBRAIN_TRAJECTORY_REGRESSION_THRESHOLD
- computeDriftScore(points): 1 - mean(cosine(emb[i], emb[i-1])) over
  embedded points; clamped [0,1]; null when <3 embedded points (D-ENG-3
  graceful degradation)
- computeTrajectoryStats(points): composed shape returning both
- TRAJECTORY_SCHEMA_VERSION = 1 — additive-only across releases (R5)

MCP op (src/core/operations.ts):
- find_trajectory: scope read, NOT localOnly. Routes through
  sourceScopeOpts(ctx) for federated isolation AND threads ctx.remote
  for visibility filtering. Strips raw Float32Array embeddings from the
  wire shape; converts valid_from to YYYY-MM-DD string
- Registered in operations array after find_experts
- FIND_TRAJECTORY_DESCRIPTION in operations-descriptions.ts

CLIs:
- gbrain eval trajectory <entity> [--metric M] [--since D] [--until D]
  [--limit N] [--json] — chronological human view with [REGRESSION] inline
  annotation; thin-client routing via callRemoteTool(find_trajectory).
  Dispatched in src/commands/eval.ts sub-subcommand block
- gbrain founder scorecard <entity> [--since D] [--until D] [--json] —
  pure aggregation over Phase 2's substrate. Four signals:
  claim_accuracy (over resolved takes), consistency, growth_trajectory,
  red_flags. computeFounderScorecard exported for tests.
  Registered as top-level command in cli.ts; added to CLI_ONLY set

Tests (45 cases across 5 files):
- test/engine-find-trajectory.test.ts: 18 cases — chronological order,
  source scoping (scalar + federated), visibility filter on remote=true,
  metric + since/until filters, regression detection at threshold
  boundaries, drift score with various embedding states
- test/operations-find-trajectory.test.ts: 9 cases — op registration,
  param validation, JSON envelope shape, R5 schema_version: 1,
  embedding stripped from wire, R6 visibility filter, source scoping
- test/eval-trajectory.test.ts: 7 cases — arg parsing, --help,
  --json envelope, regression annotation, --metric filter, empty entity
- test/founder-scorecard.test.ts: 9 cases — empty inputs no-NaN (G2),
  claim_accuracy math, consistency math, growth_trajectory math,
  red_flags fire for regression / narrative_drift / missed_prediction
- test/eval-contradictions/no-valid-until-write.test.ts: 4 cases —
  R1 (probe never writes valid_until under eval-contradictions/) +
  R8 (only allow-listed files write valid_until anywhere in src/)

* chore: v0.35.6.0 — CHANGELOG + VERSION + docs + migration note

Bumps to v0.35.6.0 (next-minor after master's v0.35.5.1 — typed-claim
substrate + trajectory + founder scorecard is a new user-facing
feature surface, not a fix).

- VERSION + package.json synced
- CHANGELOG.md release-summary block in the wave-style voice, lead with
  what the user can now DO. Sections: typed metric claims in the fence,
  chronological metric trajectories, founder scorecard, MCP
  find_trajectory op, cycle re-run idempotency fix, embedding-on-insert
  fix, valid_from precedence fix. To-take-advantage-of block with
  verification + opt-in fence syntax example
- CLAUDE.md Key Files entry consolidating the wave across

* docs: post-ship sync for v0.35.7.0 — trajectory + founder scorecard

- README.md: add `gbrain eval trajectory` to EVAL section, add new
  TEMPORAL block covering `gbrain founder scorecard` + the
  GBRAIN_TRAJECTORY_REGRESSION_THRESHOLD env override; add v0.35.7
  "What's new" paragraph below the v0.28.8 LongMemEval blurb
- AGENTS.md: new bullet under Common tasks teaching agents to reach for
  `gbrain eval trajectory` / `gbrain founder scorecard` / the
  `find_trajectory` MCP op when asked to evaluate a founder/company
  over time
- docs/contradictions.md: append "Temporal axis follow-on (v0.35.3.1 +
  v0.35.7)" subsection under See also, cross-linking the trajectory
  substrate and naming the auto-supersession.ts:4 invariant preserved
  by both the verdict enum (probe side) and consolidate's valid_until
  writeback (cycle side)
- CLAUDE.md: fix stale (v0.35.4) tag on the trajectory entry to
  (v0.35.7) — version got rebumped twice during the merge wave
- skills/migrations/v0.35.7.md renamed to v0.35.7.0.md for consistency
  with the v0.35.0.0.md / v0.14.0.md / etc naming convention
- llms-full.txt regenerated to reflect the CLAUDE.md edit

Coverage map (Diataxis):
  /eval trajectory CLI       ✅ ref (README, AGENTS) ✅ how-to (CHANGELOG) ❌ tutorial
  /founder scorecard CLI     ✅ ref (README, AGENTS) ✅ how-to (CHANGELOG) ❌ tutorial

No tutorial / explanation gaps worth filling in this PR — the migration
note's fence-syntax example already covers the "first typed claim"
walkthrough. ARCHITECTURE diagrams not drifted (the trajectory work
extends existing facts/takes infrastructure; no new component boxes).

 		4446e9f9d2 v0.35.5.0 fix wave: bootstrap + orphans + think MCP + worktree + walker (#1111) 
* fix(bootstrap): extend probes for files/oauth_clients/sources.archived* + add MIGRATIONS introspection guard

Adds 7 new forward-reference probes to applyForwardReferenceBootstrap on
both engines, closes the column-only forward-ref class via a new
MIGRATIONS-source introspection contract test.

New probes:
- files.source_id + files.page_id (v18 forward refs)
- oauth_clients.source_id + oauth_clients.federated_read (v60+v61+v65)
- sources.archived + archived_at + archive_expires_at (v34 promoted from JSONB)

The sources.archived* columns are the codex-flagged class: they're added
inline in v34's CREATE TABLE definition but `CREATE TABLE IF NOT EXISTS
sources` is a no-op on pre-v34 brains, so downstream visibility filters
(search/list_pages) trip on old brains. needsPagesBootstrap now folds
archive columns into its CREATE TABLE so pre-v0.18 brains get a v34-shape
sources in one go; needsSourcesArchive then only fires on the pre-v34
case (sources exists, archive cols don't).

Closes the structural bug class via test/helpers/extract-added-columns.ts:
reads src/core/migrate.ts as text and extracts every ALTER TABLE ADD
COLUMN. The new contract test asserts every (table, column) pair is
covered by EITHER the bootstrap's ALTER TABLE statements, the bootstrap's
CREATE TABLE definitions, OR the schema blob's CREATE TABLE bodies. The
column-only class (no index, no FK; just an inline CREATE TABLE column
the schema blob can't add to existing tables) is now caught at PR time.

Source-text introspection catches all three migration shapes uniformly:
- top-level `sql:` field
- `sqlFor.postgres` / `sqlFor.pglite` overrides
- handler-body `engine.runMigration(N, \`ALTER TABLE ...\`)` (v34 shape)

Pre-existing parseBaseTableColumns parser bug fixed: now strips `--` line
comments and `/* ... */` blocks before identifying column names. Without
this, a column preceded by a comment was silently dropped. Catches
pages.page_kind and others that were silently uncovered.

13 columns added by migrations but not in PGLITE_SCHEMA_SQL are exempted
with a unified rationale: they have no schema-blob forward reference;
migration handles all upgrade paths cleanly. Refreshing the schema blob
is a separate concern.

Issues closed: #1018 (v60 oauth_clients), #974 (files.source_id/page_id),
#820 (v0.13.0 migration files.page_id cascade); pre-empts the
sources.archived class before any pre-v34 brain trips on it.

Tests:
- 9 cases in test/schema-bootstrap-coverage.test.ts (5 existing + 4 new)
- helper-level unit tests cover SQL shape variants (IF NOT EXISTS,
  quoted identifiers, ALTER TABLE IF EXISTS ONLY, multi-statement)
- planted-bug regression verifies the gate actually catches new uncovered
  columns

* fix(orphans): filter soft-deleted pages on both candidate and link-source sides

Closes #1021. The v0.26.5 soft-delete invariant requires that
findOrphanPages exclude both:
  1. Candidate pages that are themselves soft-deleted
  2. Inbound links from soft-deleted source pages

Pre-fix, findOrphanPages had no deleted_at filter at all. Soft-deleted
pages with no inbound links were counted as orphans (inflating counts).
Pre-codex-tension-D11, only the candidate-side filter was planned.
Codex C11 caught the second case: a live page that has ONE inbound link
from a soft-deleted source page was hidden from orphan results — the
link still existed in the links table, the EXISTS subquery saw it, the
page looked "linked." Now the inner JOIN on pages enforces
src.deleted_at IS NULL.

Three regression tests pin the contract:
- soft-deleted page with no inbound → NOT orphan
- live page with ONLY inbound link from soft-deleted source → IS orphan
- live page with live inbound → NOT orphan (smoke check that the new
  filters don't break unchanged behavior)

Engine parity: same SQL shape on both Postgres and PGLite engines.

* fix(think): route runThink through gateway.chat adapter (closes #952)

Pre-fix, runThink instantiated `new Anthropic()` directly and read
ANTHROPIC_API_KEY from process.env. Claude Desktop's stdio MCP launch
doesn't inherit shell env, so `gbrain config set anthropic_api_key sk-...`
(writes to ~/.gbrain/config.json) never reached the SDK and every MCP
think call degraded to "no LLM available."

The adapter routes through gateway.chat() — the canonical seam per
CLAUDE.md. Gateway reads the API key from gbrain config OR env, picks
up prompt caching, rate-leases, retry, and the test seam
(__setChatTransportForTests) that v0.31.12 established.

Per plan-eng-review D10 (cross-model tension with codex C7+C8+C9+C10),
four spec points landed:

  1. Drop `new Anthropic()` direct path entirely. Every non-stub LLM
     call from runThink routes through gateway.

  2. Real availability check (NOT a false-positive `getChatModel()`
     truthy). `tryBuildGatewayClient` probes both the recipe (resolveRecipe
     throws AIConfigError on unknown providers) AND the API key (reads
     process.env + loadConfig at the gbrain config layer for parity with
     gateway's own auth resolution). Returns null on miss; runThink takes
     the graceful "no LLM available" early-return preserving the legacy
     NO_ANTHROPIC_API_KEY warning signal.

  3. Model-id normalization. resolveModel returns bare anthropic ids
     (claude-opus-4-7); gateway.chat needs provider:model. Adapter
     auto-prefixes anthropic: when the id is bare. Provider:model strings
     pass through unchanged.

  4. Response-shape conversion. ChatResult → Anthropic.Message via
     chatResultToMessage. mapStopReason translates gateway's
     provider-neutral stop reasons (end / length / tool_calls / refusal /
     content_filter / other) to Anthropic's stop_reason ('end_turn' /
     'max_tokens' / 'tool_use'); refusal/content_filter/other fall through
     to end_turn (no Anthropic equivalent). Usage tokens pass through.

`opts.client` injection preserved (test seam — see ThinkLLMClient).
`opts.stubResponse` preserved (pure-test escape).

Tests:
  - test/think-gateway-adapter.test.ts (9 cases): response shape, stop
    reason mapping, model-id normalization (bare + prefixed), provider
    unknown returns null, ANTHROPIC_API_KEY absent returns null
    (regression for legacy graceful degradation), hasAnthropicKey reads
    process.env correctly. Uses withEnv per the test-isolation contract.
  - test/think-pipeline.serial.test.ts (17 existing cases): unchanged;
    the graceful-degradation case at line 213 still produces the
    NO_ANTHROPIC_API_KEY warning because tryBuildGatewayClient returns
    null when no key is configured, taking the legacy early-return path.

Closes #952.

* fix(sync): distinguish git worktree from submodule via path-segment match (closes #889)

Pre-fix, `manageGitignore` treated every `.git`-as-file as a submodule
and skipped gitignore management. Both submodules AND worktrees use
`.git` as a file (not a directory), so the legacy
`statSync.isFile()` check couldn't discriminate. Worktrees got
misclassified as submodules and their .gitignore wasn't managed.

Per plan-eng-review D4 (chose path-segment match over absolute-vs-
relative path heuristic): the gitdir path contains:
  - `/modules/<name>` for submodules (skip — managed by parent repo)
  - `/worktrees/<name>` for worktrees (MANAGE — first-class repo)

Both are documented Git internal layouts, stable across all 4
{relative, absolute} × {modules, worktrees} combinations including the
absorbed-submodule edge case from `git submodule absorbgitdirs` (where
the submodule's gitdir flips to an absolute path).

Malformed `.git` file (no `gitdir:` prefix, IO error) → MANAGE, preserving
the pre-#889 catch{} fail-closed-toward-managing semantics.

Tests (5 new + 1 regression renamed):
  - REGRESSION: submodule relative gitdir/modules/ → skip (D49 contract)
  - absorbed submodule absolute gitdir/modules/ → skip (edge case)
  - CRITICAL: worktree absolute gitdir/worktrees/ → MANAGE (closes #889)
  - worktree relative gitdir/worktrees/ → MANAGE
  - malformed .git file → MANAGE (preserves catch behavior)
  - regular .git directory → MANAGE (existing smoke)

* fix(walkers): pruneDir helper + descent-time exclusion + transcript predicate (closes #923, #202)

Per plan-eng-review D12 (cross-model tension with codex C12+C13), three
structural changes:

1. Extract `pruneDir(name)` helper in src/core/sync.ts. Returns false for
   directory names walkers must NEVER descend into: `node_modules` (latent
   bug — no leading dot), dot-prefix dirs (`.git`, `.obsidian`, `.raw`,
   `.cache`, etc.), `ops`, and `*.raw` sidecar dirs (gbrain convention —
   `people/pedro.raw/` holds raw source for pedro.md). Walkers consult it
   at descent time BEFORE recursion, saving the IO cost of walking entire
   vendor / hidden / sidecar subtrees only to filter them at file-emit time.

2. `isSyncable` itself gains the same exclusion set (via pruneDir on each
   path segment). Closes the latent bug where node_modules markdown files
   slipped through: `node_modules/some-pkg/README.md` returned true pre-fix
   because the legacy dot-prefix check only blocked `.node_modules` (with
   a leading dot), not the actual `node_modules`. CRITICAL regression test
   in test/sync.test.ts pins the contract per IRON RULE.

3. Two walkers rewritten to use pruneDir at descent + per-walker file
   predicate at emit:
   - `walkMarkdownFiles` (src/commands/extract.ts): pruneDir + isSyncable
     ({strategy:'markdown'}). Pre-fix this walker had ONLY an ad-hoc
     dot-prefix exclusion and didn't call isSyncable at all — descended
     into node_modules, emitted markdown files from there, ignored README/
     ops/.raw filters.
   - `listTextFiles` (src/core/cycle/transcript-discovery.ts): pruneDir +
     own .txt/.md predicate. DOES NOT use isSyncable({strategy:'markdown'})
     because transcripts accept .txt and don't share markdown sync's
     README/ops exclusions (codex C12). Also made RECURSIVE — pre-fix
     it walked only the top dir, so transcripts in `corpus/2026/` were
     invisible (codex C14 — descent-time pruning is the right shape but
     the test would have passed vacuously on a non-recursive walker).

Verified blast radius before adding node_modules: every existing
isSyncable caller (sync.ts:558-561 sync filter, frontmatter.ts:264 validate,
brain-writer.ts:305 reverse-write, import.ts:454 import filter) wants
node_modules excluded — this is a latent-bug fix, not a behavior change
for any legitimate caller.

Tests:
- 7 new isSyncable cases including the node_modules CRITICAL regression
- 6 new pruneDir cases (node_modules, dot-prefix, ops, *.raw, content
  dirs that should pass, empty-string default)
- Existing extract.test.ts + extract-fs.test.ts unchanged and passing

* docs(todos): file v0.36.x follow-ups for runThink rewrite + Supabase bootstrap parity

Two follow-up TODOs filed during the v0.36 dreamy-thompson wave:

1. runThink full rewrite (D5+D7 from plan-eng-review): drop the
   ThinkLLMClient indirection now that v0.36 routes through gateway.chat.
   12+ tests need migration to __setChatTransportForTests. Blocked by
   this wave landing.

2. Supabase parity test for applyForwardReferenceBootstrap (codex C6
   residual): real Docker Postgres E2E catches schema correctness but
   not Supabase pooler/direct-pool routing. The probe uses this.sql but
   PostgresEngine.initSchema chooses a DDL connection; the divergence
   has caused multiple historical wedges (#699, #820 lineage).

Both entries include full context per the CLAUDE.md TODOS-format spec
(what, why, pros, cons, blocked-by, plan reference).

* fix(bootstrap): thread DDL connection through applyForwardReferenceBootstrap

Codex adversarial review during /ship caught a P1: initSchema selected a
DDL connection, took pg_advisory_lock(42) on it, but
applyForwardReferenceBootstrap used `this.sql` (the instance pool) inside.
Bootstrap probes ran outside the lock scope on a different connection.

Failure mode: two concurrent gbrain instances could BOTH enter the
bootstrap block on Supabase transaction-pooler setups because the
advisory lock was held on a different connection than the one running
ALTER TABLE. The pooler's statement_timeout could also kill the probes
mid-flight without affecting the lock-holder, leaving an inconsistent
schema state.

Fix: applyForwardReferenceBootstrap now accepts an optional connection
parameter. initSchema passes the DDL conn (the one holding the lock).
this.sql remains the fallback for any unit-test path that calls bootstrap
directly. PGLite engine doesn't need this change — single connection,
no pooler.

This was pre-existing (every prior probe used this.sql), but the v0.36
wave is explicitly about fixing the Supabase upgrade-wedge class. Codex's
position was correct: don't ship the wave with the underlying connection
mismatch still there. The Supabase parity TEST FIXTURE follow-up remains
on TODOS.md (test infra needed to PROVE the fix works under real pooler
topology), but the bug itself is closed.

15/15 bootstrap tests pass. Typecheck clean.

 		e493d5f44b v0.32.8 fix: multi-source bug class extermination — embed, extract, takes, patterns, integrity, migrate-engine (#860) 
* fix: thread source_id through embed --stale to fix silent discard of non-default source embeddings

listStaleChunks correctly finds chunks across all sources, but
embedOneSlug called getChunks(slug) and upsertChunks(slug, merged)
without passing sourceId. Both default to source_id='default', so
for non-default sources (e.g. media-corpus):

1. getChunks returns empty (wrong source)
2. merged array has no existing chunks to merge into
3. upsertChunks writes nothing (or errors silently)
4. Embeddings generated by the API are silently discarded

Fix:
- Add source_id to StaleChunkRow type
- Add p.source_id to listStaleChunks SQL in both postgres + pglite engines
- Extract sourceId from stale row in embed command
- Pass { sourceId } to getChunks and upsertChunks
- Group stale chunks by composite key (source_id::slug) instead of bare slug
  to handle same-slug pages across multiple sources

Verified: 97 chunks embedded across 35 pages in first run after fix.
Previously 0 non-default-source chunks were embedded across 3 full runs.

* fix: comprehensive multi-source threading for embed, listPages, and migrate-engine

Multi-source brains (e.g. with a 'media-corpus' source alongside
'default') have a pervasive bug: operations that iterate pages across
all sources then call engine methods (getChunks, upsertChunks,
getChunksWithEmbeddings) without passing sourceId. These methods all
default to source_id='default', silently operating on the wrong page
(or no page at all) for non-default sources.

Changes:

1. Page type + rowToPage: add optional source_id field so downstream
   callers can read the source from page objects returned by listPages.

2. PageFilters: add sourceId filter so listPages can scope to a single
   source (used by embed --source and future extract --source).

3. listPages (postgres + pglite): wire the sourceId filter into SQL.

4. embed command — three paths fixed:
   a. embedPage (single-slug): accepts sourceId, threads to getPage +
      getChunks + upsertChunks.
   b. embedAll (--all): reads page.source_id from listPages results,
      threads to getChunks + upsertChunks per page.
   c. embedAllStale (--stale): reads source_id from StaleChunkRow,
      groups by composite key (source_id::slug) instead of bare slug,
      threads to getChunks + upsertChunks per key.

5. embed CLI: add --source <id> flag, threaded through all paths.

6. migrate-engine: thread page.source_id through
   getChunksWithEmbeddings + upsertChunks so engine migrations don't
   lose non-default-source chunks.

7. getChunksWithEmbeddings (postgres + pglite + BrainEngine interface):
   accept optional { sourceId } to scope the chunk lookup.

8. StaleChunkRow type: add source_id field.

9. listStaleChunks SQL (postgres + pglite): add p.source_id to SELECT.

Verified: embed --stale correctly embeds 97 chunks across 35 pages
(previously 0 non-default-source chunks across 3 full runs).
embed --source media-corpus --dry-run correctly scopes to that source.

* v0.32.4 fix: multi-source threading for embed, listPages, and migrate-engine

Bump VERSION + package.json + CHANGELOG for the comprehensive multi-source
fix. Embed now threads source_id through every page → chunk handoff so
non-default sources stop silently dropping out (~22k chunks recovered on
the brain that surfaced this).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* fix: complete slugs→keys rename in embedAllStale

The composite-key rename in the prior commit missed 4 references in the
worker loop and trailing console.log, so the file failed typecheck
(`Cannot find name 'slugs'`). The author's "Verified compiling + running"
claim was false at the time of the PR.

Also drop the dead `const bySlug = byKey` alias — unused after rename.

* ci: add check-source-id-projection.sh + fix getPage/putPage projections

Two SELECT projections fed `rowToPage` without including `source_id`:
- postgres-engine.ts:562 (getPage), :609 (putPage RETURNING)
- pglite-engine.ts:505 (getPage), :548 (putPage RETURNING)

After the type-tightening in the next commit makes `Page.source_id`
required, those projections would silently produce `Page` rows with
source_id=undefined while TypeScript claims `: string`. Codex's plan
review (F2) caught this; this commit closes it.

The new `scripts/check-source-id-projection.sh` greps for the rowToPage
feeder shape (`SELECT id, slug, type, title, ...`) and fails the build
if any projection lacks `source_id`. Wired into `bun run verify`.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(engine): Page.source_id required + listAllPageRefs + validateSourceId

Three coordinated changes that unlock the Phase 3 bug-site fixes:

1. `Page.source_id` is now required (was optional, v0.31.12). The DB column
   is `NOT NULL DEFAULT 'default'` so every row has it; the type now matches.
   `rowToPage` always emits it (falls back to 'default' if a stale projection
   somehow misses the column, but `scripts/check-source-id-projection.sh` is
   the primary guard).

2. `BrainEngine.listAllPageRefs()` returns `Array<{slug, source_id}>` ordered
   by `(source_id, slug)`. Cheap cross-source enumeration for hot loops in
   extract-takes / extract / integrity that previously used
   `getAllSlugs() → getPage(slug)` (N+1 query AND silently defaulted to
   'default'). PGLite + Postgres parity.

3. `validateSourceId(id)` in utils. Allows `[a-z0-9_-]+` only. Used by the
   per-source disk-layout fix coming in Phase 3 before any
   `join(brainDir, source_id, ...)` call so source_id can't traverse out
   of brainDir.

Deferred to v0.33 follow-up:
- D2 strict tightening of BrainEngine slug-method signatures (the compile-
  time guard for "future getPage calls must pass sourceId")
- F3 OperationContext.sourceId required at MCP boundary
- F4 LinkBatchInput / TimelineBatchInput required source_id fields
- D6 forEachPage / listPagesAfter helpers (use listPages directly for now)

Those are nice-to-have guardrails for future regressions. Current commit's
correctness via D7 + listAllPageRefs is what blocks the Phase 3 bug-site
fixes from working multi-source.

* fix: thread source_id through cycle phases, extract, integrity, migrate-engine

Five bug sites that previously called slug-only engine methods inside a
loop over pages, silently defaulting to source_id='default' for every
non-default-source page. Now all five use listAllPageRefs to enumerate
(slug, source_id) pairs and thread sourceId through to engine.getPage,
getTags, addLink, addTimelineEntry, getRawData, getVersions, etc.

Site-by-site:

- src/core/cycle/extract-takes.ts: listAllPageRefs replaces N+1
  getAllSlugs+getPage. Takes for non-default-source pages now extract.

- src/core/cycle/patterns.ts + synthesize.ts: reverseWriteSlugs renamed
  to reverseWriteRefs with Array<{slug, source_id}> contract. Disk
  layout (F6): non-default sources land at brainDir/.sources/<id>/<slug>.md
  so same-slug-different-source pages don't collide. Default-source
  pages stay at brainDir/<slug>.md so single-source brains see no
  change. source_id validated against [a-z0-9_-]+ at write time to
  prevent path traversal.

- src/commands/extract.ts: extractLinksFromDB + extractTimelineFromDB
  use listAllPageRefs. Cross-source link resolution rule (F10): origin's
  source wins, fall back to default, else skip (don't silently push a
  wrong-source edge). addLinksBatch / addTimelineEntriesBatch now fill
  from_source_id / to_source_id / origin_source_id / source_id so
  multi-source JOINs target the correct page row.

- src/commands/integrity.ts: same listAllPageRefs pattern in both the
  primary scan loop and the auto-repair loop.

- src/commands/migrate-engine.ts: end-to-end source_id threading
  (page + tags + timeline + raw + versions + links). Resume manifest
  keyed on `${source_id}::${slug}` so multi-source resumes don't
  collide on same-slug rows (pre-fix entries treated as default for
  back-compat).

test/cycle-synthesize-slug-collection.test.ts updated for the new
collectChildPutPageSlugs return shape (Array<{slug, source_id}>
instead of string[]).

* test(e2e): multi-source bug class regression + CHANGELOG + e2e-test-map wire-up

test/e2e/multi-source-bug-class.test.ts — 7-case PGLite regression suite
pinning every bug site fixed in this PR:
  - listAllPageRefs ordering by (source_id, slug) [F11]
  - getPage with sourceId picks the right (source, slug) row [F2]
  - extract-takes processes both alice pages independently
  - listPages filters correctly with PageFilters.sourceId
  - addLinksBatch with from/to_source_id targets the right rows [F4]
  - validateSourceId rejects path traversal [F6]
  - reverse-write disk layout uses .sources/<id>/<slug>.md [F6]

No DATABASE_URL needed (PGLite in-memory + canonical R3+R4 pattern).

Wire into scripts/e2e-test-map.ts so changes to any of the 6 touched
source files automatically trigger this test.

CHANGELOG expanded from the embed-only narrative to cover the full
bug-class extermination — extract, takes, patterns, integrity,
migrate-engine, plus the per-source disk layout, the CI gate, and
the new listAllPageRefs primitive. Voice: lead with what users can
DO that they couldn't before; real numbers from the production brain
that surfaced it.

* fix(integrity): batch path scans (source_id, slug) pairs too

The batch-load fast path in scanIntegrity used `SELECT DISTINCT ON (slug)`,
which silently collapsed multi-source duplicate slugs into a single scan —
the same bug class this PR fixes. test/e2e/integrity-batch.test.ts had a
case pinning the broken behavior ("scan once, not once-per-source") that
asserted batchResult.pagesScanned===1 for two real (source, slug) rows.

Switching the projection from `DISTINCT ON (slug)` to a plain `SELECT ...
ORDER BY source_id, slug` makes batch + sequential paths report the same
count (2) and matches the v0.32.4 listAllPageRefs walk.

Test renamed + assertion flipped to lock in the correct multi-source-aware
behavior: both paths now report 2, not 1.

* docs: sync CLAUDE.md + llms bundles for v0.32.4

CLAUDE.md annotations updated on the 4 files that materially changed in
this PR's bug-class extermination:

- src/core/engine.ts — new listAllPageRefs() method
- src/core/utils.ts — new validateSourceId() helper + Page.source_id
  required field plumbing
- src/commands/integrity.ts — batch projection switched from DISTINCT ON
  (slug) to ORDER BY (source_id, slug) so multi-source scans aren't
  collapsed
- scripts/check-source-id-projection.sh (NEW entry) — CI guard against
  SELECT projections that drop source_id

Plus a new test inventory entry for test/e2e/multi-source-bug-class.test.ts
in the E2E section.

llms-full.txt regenerated per CLAUDE.md's iron rule. llms.txt is unchanged
(just an index).

 		9a5606af6d v0.32.6 feat: brain-consistency probe + doctor + MCP + dream-cycle wire-up (#901) 
* feat(eval-contradictions): types + pure helpers for v0.33.0 probe

Foundational module for the contradiction measurement probe (v0.33.0 plan).
Pure, hermetic, no engine or LLM dependencies. Sets the wire contract for
the rest of the implementation.

- types.ts: schema_version + PROMPT_VERSION + TRUNCATION_POLICY constants,
  ProbeReport + ContradictionPair + JudgeVerdict + cache/run row shapes.
- calibration.ts: Wilson 95% CI on the headline percentage with exact
  clamping at p=0 and p=1 (floating-point overshoot regression guard);
  small_sample_note when n<30.
- judge-errors.ts: first-class typed error collector (Codex fix — bias
  guard for the silent-skip-on-throw decision); classifier maps to
  parse_fail/refusal/timeout/http_5xx/unknown.
- severity-classify.ts: parseSeverity defaults to 'low' on garbage input;
  bucketBySeverity + buildHotPages (descending rank + tie-break by severity).
- date-filter.ts: three-rule A1 pre-filter — same-paragraph-dual-date
  beats the separation rule (flip-flop case); missing dates falls through
  to the judge; only "both explicit AND >30d apart" actually skips.

51 hermetic tests across the four pure modules; typecheck clean.

* feat(eval-contradictions): schema migrations + engine methods (v0.33.0)

Adds the persistent surface the contradiction probe needs: two new tables
plus five BrainEngine methods, mirrored cleanly across PGLite + Postgres.

Migrations v51 + v52 (idempotent on both engines):
  - eval_contradictions_cache: composite PK on (chunk_a_hash, chunk_b_hash,
    model_id, prompt_version, truncation_policy) per Codex outside-voice
    fix; verdict JSONB; expires_at-driven TTL.
  - eval_contradictions_runs: one row per probe run; Wilson CI bounds,
    judge-error totals, source-tier breakdown, full report_json.

Engine methods (interface + 2 impls each):
  - listActiveTakesForPages(pageIds, opts): P1 batched per-page fetch.
    Single WHERE page_id = ANY($1) AND active = true; replaces the O(K)
    loop the probe would otherwise pay per query.
  - writeContradictionsRun(row): M5 time-series insert; idempotent on
    run_id via ON CONFLICT DO NOTHING.
  - loadContradictionsTrend(days): M5 history read, newest first.
  - getContradictionCacheEntry(key): P2 cache lookup; 5-component key
    includes prompt_version + truncation_policy.
  - putContradictionCacheEntry(opts): cache upsert with TTL refresh.
  - sweepContradictionCache(): periodic expired-row purge.

JSONB writes use sql.json() on Postgres (matches existing eval_takes_quality
+ raw_data patterns; not the literal-template-tag pattern banned by
scripts/check-jsonb-pattern.sh). PGLite uses $N::jsonb positional binds.

17 hermetic tests on PGLite cover P1 (4 cases: empty, grouped, supersede-
excludes, holder-allow-list), M5 (5 cases: write+read, idempotent run_id,
newest-first, days-window, JSONB round-trip), P2 (6 cases: miss, put-get,
prompt-version differs, truncation differs, upsert refreshes, sweep
deletes expired). Existing 109 migrate + bootstrap tests still green.

Schema mirror in pglite-schema.ts; source.sql regenerated to schema-embedded.

* feat(eval-contradictions): cross-source + cost-tracker + cache wrappers

Three pure-orchestration modules between the engine surface and the
runner. Each is independently testable; the cache wrapper does hit the
PGLite engine end-to-end since its job is to round-trip through P2.

- cross-source.ts (M6): classifySlugTier maps a slug to curated/bulk/other
  using DEFAULT_SOURCE_BOOSTS (boost > 1.05 = curated, < 0.95 = bulk).
  buildSourceTierBreakdown produces the {curated_vs_curated,
  curated_vs_bulk, bulk_vs_bulk, other} counts; order-independent on
  the pair members.

- cost-tracker.ts (A2 + P3): estimateUpperBoundCost for pre-flight refuse.
  CostTracker records judge calls (per-token-pricing per model) AND
  embedding calls (Codex P3 fix). Soft-ceiling semantics documented
  in the estimate_note string surfaced in the final report (Codex
  caveat: "hard ceiling" was overclaimed for token estimates).
  Anthropic + OpenAI pricing baked in; unknown models fall back to
  Haiku rates.

- cache.ts (P2 wrapper): hashContent (sha256), buildCacheKey with
  lex-sorted (a, b) so verdicts are order-independent and key bakes in
  PROMPT_VERSION + TRUNCATION_POLICY (Codex outside-voice fix). JudgeCache
  class tracks hits/misses for the run report. Shape validation guards
  against corrupt rows: a cache row that doesn't parse as JudgeVerdict
  treats as a miss instead of crashing downstream.

40 hermetic tests across the three modules. Cache tests hit PGLite for
real round-trip coverage of the new engine methods committed in C2.

* feat(eval-contradictions): judge + auto-supersession + fixture-redact

Three modules that together turn an LLM into a contradiction probe and
its output into actionable resolutions.

- judge.ts: judgeContradiction() is the single LLM call. Query-conditioned
  prompt (Codex outside-voice fix — the judge sees what the user asked).
  Holder context for take pairs (C3). UTF-8-safe truncation at maxPairChars
  (default 1500, --max-pair-chars overridable; C4 wire-up). C1
  double-enforcement: orchestrator filters contradicts:true with confidence
  < 0.7 to false regardless of prompt rules. parseJudgeJSON is a 3-strategy
  generic parser (direct → fence-strip → trailing-comma + quote + first-{}
  extraction) — we don't reuse parseModelJSON because that's shape-locked
  to cross-modal-eval's scores payload. Refusal detection via stopReason
  AND text-pattern fallback. chatFn injection for hermetic tests.

- auto-supersession.ts (M7): proposeResolution classifies each pair into
  takes_supersede / dream_synthesize / takes_mark_debate / manual_review
  and emits a paste-ready CLI command. Judge's hint wins on cross-slug
  pairs (it has semantic context); structural fallback prefers
  dream_synthesize when either side is a curated entity slug
  (companies/, people/, deals/, projects/). pairToFinding merges a pair +
  verdict into a ContradictionFinding.

- fixture-redact.ts (T2): privacy-redacted pass for the gold fixture
  build. Layers PII scrubber (v0.25.0 eval-capture-scrub) + slug rewrites
  (people/<name> → people/alice-example, deterministic per session) +
  capitalized firstname-lastname detection + monetary obfuscation
  (multiply revenues by session salt to preserve magnitude shape).
  isCleanForCommit is the pre-commit safety net: blocks if any raw name
  or email shape survives. Audit trail records every redaction made.

60 hermetic tests. Judge tests use direct chatFn stub (cleaner than
module-level transport seam for one-shot wrapper).

* feat(eval-contradictions): trends + runner orchestrator (v0.33.0)

The heart of the probe — runner.ts ties every prior module together,
trends.ts writes one row per run to eval_contradictions_runs and produces
the trend chart for the CLI `trend` sub-subcommand.

runner.ts:
  - Pair generation: cross-slug across top-K results (same-slug skipped)
    + intra-page chunk-vs-take via P1 batched listActiveTakesForPages.
  - A1 date pre-filter wired: pairs separated by >30 days skip without
    judge calls; same-paragraph-dual-date overrides separation rule
    (flip-flop case sees the judge).
  - A3 deterministic sampling: combined_score DESC, slug-lex tiebreaker,
    stable across re-runs.
  - A2 soft budget ceiling: pre-flight estimate refuses without --yes;
    mid-run cumulative cost stops the run and emits a partial report.
  - P2 cache integration: lookup before judge call, store after; hit/miss
    counters drive the cache stats block in the report.
  - C2 first-class judge_errors: every throw counted via the typed
    collector, surfaced in report.judge_errors with the no-silent-skip
    `note` field.
  - Wilson CI on the headline percentage; small_sample_note when n<30.
  - source_tier_breakdown + hot_pages aggregated across all findings.
  - AbortSignal propagation for cancellation mid-run.
  - PreFlightBudgetError exported as a discriminable rejection class.
  - Hermetic via judgeFn + searchFn dependency injection — runner tests
    stub both without ever touching the real gateway or hybridSearch.

trends.ts:
  - writeRunRow flattens a ProbeReport into the eval_contradictions_runs
    row shape, including Wilson CI bounds + duration_ms.
  - loadTrend reads back as typed TrendRow[].
  - renderTrendChart produces a fixed-width ASCII bar chart; empty input
    prints a friendly message naming the command to populate runs.

41 new hermetic tests on PGLite (15 trends, 26 runner). Full
eval-contradictions suite at 194/194 across 13 files.

* feat(eval-contradictions): CLI + eval dispatch + mini fixture (v0.33.0)

User-facing surface: `gbrain eval suspected-contradictions [run|trend|review]`.
Engine-required sub-subcommand, dispatched via the existing eval.ts pattern
(matches `replay`).

Run mode:
  --queries-file FILE | --query "..." | --from-capture  (mutually exclusive)
  --top-k N=5  --judge MODEL=claude-haiku-4-5  --limit N
  --budget-usd N (default $5 TTY / $1 non-TTY) --yes
  --output FILE  --max-pair-chars N=1500
  --sampling deterministic|score-first  --no-cache  --refresh-cache  --json

Trend mode: --days N=30 [--json]
Review mode: --severity low|medium|high  --since YYYY-MM-DD

A4 wired: --from-capture detects empty eval_candidates and exits 2 with
hint naming GBRAIN_CONTRIBUTOR_MODE=1 / eval.capture config key.

Human summary on stderr always prints Wilson CI band, judge_errors counts
broken out by class, cache hit-rate, source-tier breakdown, hot pages.
Partial-report warning when mid-run budget cap fires.

Run-row persistence (M5) writes to eval_contradictions_runs every successful
run; subsequent `trend` and `review` invocations read from there.

PreFlightBudgetError surfaces as exit 1 with the calculated estimate + cap
in the message — operators see the exact number to pass to --budget-usd
or override with --yes.

TrendRow type extended with report_json so `review` can fetch the latest
run's findings without a second query.

test/fixtures/contradictions-mini.jsonl: 5 redacted queries for CLI smoke.

Full eval-contradictions suite: 194 hermetic tests across 13 files. Real-
brain CLI smoke covered by the E2E in commit 9.

* feat(eval-contradictions): doctor + MCP + synthesize integrations (M1+M2+M3)

Three thin wire-ups that turn the probe's output into action surfaces:

M1 (doctor): src/commands/doctor.ts adds a `contradictions` check after
the eval_capture check. Reads loadContradictionsTrend(7), surfaces the
latest run's headline + severity breakdown + Wilson CI band + first 3
high-severity findings with paste-ready resolution commands. ok status
when no runs exist or no findings; warn when high-severity > 0. Graceful
skip when the table doesn't exist yet (pre-migration brain).

M3 (MCP): src/core/operations.ts adds `find_contradictions` op (scope:
read, NOT localOnly — agent-callable over HTTP MCP). Params: slug
(substring match), severity (low|medium|high), limit. Reads
loadContradictionsTrend(30), returns the latest run's findings filtered.
NOT in the subagent allowlist by design — user-initiated only, not
autonomous-action surface. New FIND_CONTRADICTIONS_DESCRIPTION constant
in operations-descriptions.ts.

M2 (synthesize): src/core/cycle/synthesize.ts pre-fetches the latest
probe findings once at phase start (loadPriorContradictionsBlock helper)
and threads up to 5 highest-severity items into buildSynthesisPrompt as
an informational block. Subagent sees what to reconcile when writing
compiled_truth to flagged slugs. Empty trend yields empty block (existing
behavior unchanged on fresh installs). Try/catch around the engine call
keeps synthesize robust even when the contradiction tables don't exist
yet.

11 new hermetic tests for the MCP op (registry presence, scope, empty
case, slug+severity+limit filters) and the M1/M2 data-shape contracts
(end-to-end runDoctor coverage deferred to commit 9's E2E because doctor
calls process.exit).

Full eval-contradictions suite: 226/226 across 15 test files.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(eval-contradictions): build-contradictions-fixture script (T2)

Local-only operator script for building the privacy-redacted gold fixture
used by the precision/recall test (deferred to v0.34 when probe data
informs the labeling). Runs against the user's REAL brain via the local
gbrain engine config; never auto-run in CI.

Flow:
  1. Read --queries-file (JSONL); spin up engine via loadConfig +
     toEngineConfig + createEngine + connectWithRetry.
  2. Run the contradiction probe with --no-cache and a stubbed judgeFn
     that captures candidate pairs without spending tokens.
  3. Interactive prompts (skipped under --non-interactive): for each
     candidate, the operator labels y/n/skip + severity + axis.
  4. Apply the v0.33.0 fixture-redact passes (slug rewrite, name
     placeholders, monetary obfuscation, PII scrubber).
  5. Pre-commit safety gate: every text field passes isCleanForCommit;
     anything that fails gets a [REDACT?] sentinel + an _operator_review
     marker on the JSONL line, and the script exits 1 so the operator
     can't accidentally commit unredacted output.

Audit comment block at the top of the JSONL records every redaction
the session made (slug→placeholder, name→placeholder, monetary
multiplication) so reviewers can see what was changed.

Usage:
  bun run scripts/build-contradictions-fixture.ts \\
    --queries-file FILE.jsonl \\
    [--top-k N] [--judge MODEL] [--max-pairs N] [--output PATH] \\
    [--non-interactive]

Output defaults to test/fixtures/contradictions-eval-gold.jsonl.

Typecheck clean; redactor + isCleanForCommit guard tested separately
in test/eval-contradictions-fixture-redact.test.ts.

* test(e2e): real-Postgres E2E for contradiction probe (v0.33.0, T1)

Required-on-DATABASE_URL E2E covering Postgres-specific behavior that
PGLite can't exercise. Six surface areas, 12 cases total. All pass on
fresh pgvector/pgvector:pg16:

1. Migrations v51 + v52 apply cleanly; both tables exist in
   information_schema; Wilson CI columns are REAL; composite PK on
   eval_contradictions_cache includes prompt_version + truncation_policy
   (Codex outside-voice fix pinned at the schema level).

2. JSONB round-trip on Postgres: writeContradictionsRun + loadTrend
   preserves nested object shapes (regression guard against the v0.12
   double-encode bug class). Confirmed via jsonb_typeof = 'object', not
   'string'.

3. P2 cache with real now(): lookup/upsert round-trip, expired rows
   hidden from lookup, sweepContradictionCache deletes them, and
   different prompt_version is a separate cache key.

4. M5 trend semantics: TIMESTAMPTZ ordering DESC is stable on real PG;
   days-window filter via ran_at >= cutoff correctly excludes/includes
   backdated rows.

5. find_contradictions MCP op end-to-end: empty case returns "No probe
   runs" note; populated case returns latest run findings with slug
   substring + severity filters applied.

Verified locally against pgvector:pg16 on port 5434 — all 12 cases pass.
Skips gracefully when DATABASE_URL is unset per gbrain E2E convention.

* v0.33.0 feat: brain-consistency probe + doctor + MCP + dream-cycle wire-up

VERSION 0.32.0 → 0.33.0. package.json + CHANGELOG.md + llms-full.txt synced.

Headline: gbrain learns to detect its own integrity drift.

  - new command: gbrain eval suspected-contradictions [run|trend|review]
  - new MCP op: find_contradictions(slug?, severity?, limit?)
  - new doctor check: contradictions (paste-ready resolution commands)
  - new dream-cycle hook: synthesize reads prior contradictions per slug
  - new schema: v51 (eval_contradictions_cache) + v52 (eval_contradictions_runs)
  - 6 new engine methods (listActiveTakesForPages, write/load run, P2 cache trio)

Codex outside-voice review folded in:
  - Command name "suspected-contradictions" (was "contradictions" — describes
    what the tool actually does, not what it pretends to evaluate)
  - judge_errors first-class output (not silent stderr — biased denominator)
  - prompt_version + truncation_policy in cache key (prompt edits cleanly
    invalidate prior verdicts)
  - Wilson 95% CI on headline % + small_sample_note when n<30
  - Query-conditioned judge prompt (sees user's query, not just two chunks)
  - Deterministic sampling for prevalence metric (stable cache hit-rate)

Decision criterion for the bigger swing (chunk-level revises field):
  Wilson CI lower-bound:
    <5%  → source-boost + recency-decay + curated pages handle the load
    5-15% → operator's call
    >15% → plan for v0.34+

New docs:
  - docs/contradictions.md (architecture, severity rubric, action criteria)
  - docs/eval-bench.md extended (nightly cadence + trend workflow)
  - skills/migrations/v0.33.0.md (post-upgrade agent instructions)

Full test suite green at the cut:
  - 226 hermetic unit tests across 15 files (eval-contradictions-*)
  - 12 real-Postgres E2E (DATABASE_URL=...; verified locally on pgvector:pg16)
  - typecheck clean
  - build:llms regenerated and the test/build-llms.test.ts gate passes

 		a73108b26f v0.32.2 feat: facts join system-of-record + 3-layer privacy + CI invariant gate (#885) 
* schema: migration v51 facts_fence_columns + fresh-install parity

v0.32.2 commit 1/11.

Facts become FS-canonical via a `## Facts` fence on entity pages (mirror of
takes-fence). row_num + source_markdown_slug are the round-trip columns the
fence parser uses to reconcile markdown → DB.

Schema changes:
- ALTER TABLE facts ADD COLUMN IF NOT EXISTS row_num INTEGER
- ALTER TABLE facts ADD COLUMN IF NOT EXISTS source_markdown_slug TEXT
- CREATE UNIQUE INDEX idx_facts_fence_key (source_id, source_markdown_slug,
  row_num) WHERE row_num IS NOT NULL

Both columns nullable: pre-v0.32 rows don't have them until commit 6's
v0_32_2 orchestrator backfills via fence-append. The partial WHERE clause is
the Codex R2 collision guard — without it, two pre-v51 NULL-row_num rows on
the same (source_id, source_markdown_slug) coordinate would collide and fail
the migration on any populated v0.31 brain.

Fresh-install parity: the v40 CREATE TABLE block now declares the columns
from the start, so a brand-new install hits a single CREATE that already
has them and the v51 ALTERs no-op via IF NOT EXISTS. Existing brains pick
them up through the v51 migration.

Idempotent under all states (re-runs are no-ops). Metadata-only ALTERs on
PG 11+ and PGLite — no table rewrite. Partial-index syntax verified
against v40's existing idx_facts_unconsolidated precedent.

Tests:
- 6 new v51 cases in test/migrate.test.ts covering name, ADD COLUMN shape,
  nullable contract, partial-unique-index keys, the WHERE-NULL collision
  guard, and LATEST_VERSION progression.
- All 109 migration tests pass (was 103); schema walks 15 → 51 cleanly.

* feat: facts-fence.ts + extract shared escape helpers from takes-fence

v0.32.2 commit 2/11.

New: src/core/facts-fence.ts — structural mirror of src/core/takes-fence.ts.
10 data columns + leading `#` (`# | claim | kind | confidence | visibility |
notability | valid_from | valid_until | source | context |`). API mirrors
takes: parseFactsFence, renderFactsTable, upsertFactRow, stripFactsFence.

Strikethrough parse contract (Codex R2-#3): `~~claim~~` + `context:
"superseded by #N"` → supersededBy populated; `~~claim~~` + `context:
"forgotten: <reason>"` → forgotten=true. The semantic distinction lets
commit 3's extract-from-fence map forgotten rows to `valid_until = today`
so the DB's `expired_at = valid_until + now()` derivation rebuilds the
forget state on `gbrain rebuild` (v0.32.3 follow-up).

Refactor: extracted shared primitives to src/core/fence-shared.ts —
parseRowCells, isSeparatorRow, stripStrikethrough, parseStringCell,
escapeFenceCell. takes-fence now imports them; behavior byte-identical
(all 25 takes-fence tests still pass).

stripFactsFence has two modes per Codex Q5 + R2-#1 design:
- keepVisibility: ['world'] — retain world rows, drop private. The mode
  both the chunker (Layer A) and get_page over remote MCP (Layer B) use.
  Private fact bytes never reach content_chunks.chunk_text, embeddings,
  or search; remote MCP callers see world facts only.
- default / empty array — drop the entire fence block. Defensive deny-
  by-default at the privacy boundary.

Tests: 36 new cases in test/facts-fence.test.ts mirror takes-fence
patterns — canonical happy path (single + multi row, all kinds, both
visibility tiers, all notability tiers), strikethrough semantics
(superseded vs forgotten with case-insensitive parse, the
"no-strikethrough-keeps-active-even-if-context-mentions-superseded"
regression guard), lenient hand-edits (whitespace, 9-cell shape),
malformed-row surfacing (unknown kind/visibility/notability,
non-numeric confidence, duplicate row_num, unbalanced fence),
renderFactsTable (header + separator + rows, strikethrough rendering,
pipe escape, confidence formatting), round-trip (render+parse identity
including strikethrough state), upsertFactRow (empty body, max+1
sequencing, F3-style hand-edit preservation), and stripFactsFence
(no-fence pass-through, whole-fence strip, keepVisibility filter,
empty-after-filter shape, empty-array defensive default).

76/76 tests across facts-fence + takes-fence + chunker-recursive pass.

* feat: src/core/facts/extract-from-fence.ts — pure ParsedFact → NewFact mapper

v0.32.2 commit 3/11.

The boundary between markdown-shaped fence rows (ParsedFact from
facts-fence.ts) and DB-shaped engine rows (NewFact). Pure function, no
I/O. Resolves Codex Q7: engines stay markdown-unaware. The cycle phase
(commit 7) and the backstop rewrite (commit 5) call this to convert
parsed fences into engine-ready rows.

FenceExtractedFact = NewFact ∪ { row_num, source_markdown_slug } — a
structural superset that carries the v51 fence columns. Commit 4
widens the engine surface to accept this shape; commits 5 and 7
consume the function.

Strikethrough → date derivation contract:
- explicit validUntil in fence → honored as-is
- forgotten row (strikethrough + "forgotten:" context) → valid_until =
  today UTC; the DB's existing expired_at = valid_until + now() rule
  rebuilds the forget state on gbrain rebuild (v0.32.3 follow-up)
- supersededBy row without explicit validUntil → null; consolidator
  phase fills this in from the newer row's valid_from
- inactive-unrecognized (strikethrough + neither flag) → today; honors
  the user's strikethrough intent for unrecognized contexts

Determinism guard: nowOverride opt makes the today-stamping testable
without freezing global Date. Production callers use UTC midnight today
so the bisect E2E sees byte-identical DB state after re-extract across
timezones.

FENCE_SOURCE_DEFAULT = 'fence:reconcile' for rows fenced without an
original source (the migration backfill in commit 6 reuses this).

Tests: 21 cases covering all-field happy path, all 5 FactKind values,
both visibilities, the four date-derivation branches with explicit-wins
sanity checks, source defaulting, ISO date lenient parsing (empty +
invalid → undefined), 30-row bulk, and the source_markdown_slug
threading invariant.

* feat: engine.insertFacts batch + deleteFactsForPage on both engines

v0.32.2 commit 4/11.

New BrainEngine surface for the reconciliation path:

  insertFacts(
    rows: Array<NewFact & { row_num: number; source_markdown_slug: string }>,
    ctx: { source_id: string },
  ): Promise<{ inserted: number; ids: number[] }>

  deleteFactsForPage(slug: string, source_id: string): Promise<{ deleted: number }>

insertFacts is the only entry point that persists v51 columns
(row_num, source_markdown_slug). Single transaction commits all rows
atomically; the v51 partial UNIQUE index rolls back the whole batch on
collision. Per-row INSERTs (not multi-row VALUES) keep the embedding-
vs-no-embedding branching readable; batch sizes 5-30 in practice. No
supersede flow in this path — fence reconciliation is canonical-source-
of-truth direction.

deleteFactsForPage scopes by (source_id, source_markdown_slug). Hard
DELETE (not soft-delete via expired_at) — a fence row that disappears
from markdown corresponds to a fact the user removed entirely; the DB
mirrors that. Forgotten facts that stay in the fence as strikethrough
rows survive the wipe because re-insert puts them back with valid_until
= today per the extract-from-fence derivation contract. Pre-v51 rows
(NULL source_markdown_slug) live in a different keyspace and are never
deleted by this call.

Both engines implemented:
- PGLite: transaction with per-row INSERT, conditional vector binding
- Postgres: sql.begin() transaction, postgres.js tagged template

Tests (13 new cases in test/insert-facts-batch.test.ts):
- empty batch returns inserted:0
- single-row + multi-row persistence, ids in input-order
- all NewFact + v51 columns round-trip
- v51 partial UNIQUE rolls back whole batch on collision
- different source_markdown_slug + different source_id values don't
  collide on same row_num
- deleteFactsForPage scoping (same source different page; same page
  different source; pre-v51 NULL-source_markdown_slug rows untouched)
- delete-then-reinsert round-trip (the cycle-phase pattern)

226 tests pass across facts surface + migrate + takes-fence (no
regressions in adjacent code).

* feat: markdown-first fact write path in src/core/facts/backstop.ts

v0.32.2 commit 5/11.

THE rewrite. Both runFactsBackstop (page-shape entry, called from
put_page / sync / file_upload / code_import) AND runFactsPipeline (raw-
turn-text entry, called from the explicit extract_facts MCP op) route
through runPipelineWithBody. Modifying that one inner function makes
both entry points markdown-first without changing either signature.
Resolves Codex R2-#2 surface gap.

New: src/core/facts/fence-write.ts — writeFactsToFence orchestrator +
lookupSourceLocalPath helper.

Pipeline (post-dedup, per entity_slug group):
1. Acquire FS page-lock via src/core/page-lock.ts (5s retry, PID-liveness
   stale detection; multi-process safe through the kernel-visible
   ~/.gbrain/page-locks/<sha-of-slug>.lock file)
2. Read entity page from <source.local_path>/<slug>.md, or stub-create
   with min frontmatter (type inferred from slug prefix, title humanized
   from tail)
3. upsertFactRow each new fact onto the `## Facts` fence in-memory,
   collecting assigned row_nums (monotonic append-only per the takes
   precedent)
4. Atomic write: writeFileSync(.tmp) → re-readFileSync(.tmp) →
   parseFactsFence(.tmp) → on warnings: leave .tmp + JSONL surface +
   NO DB write; on clean: renameSync(.tmp → file). Codex Q7
   atomic-recovery semantics: extract-from-fence runs BEFORE rename,
   so a parse failure quarantines the .tmp without corrupting the
   canonical file
5. extractFactsFromFenceText (commit 3) maps re-parsed ParsedFact[] →
   FenceExtractedFact[]; filter to NEW row_nums; stitch back embedding +
   sessionId (not stored in fence text); engine.insertFacts batch
   (commit 4)

Three structural fallbacks to legacy DB-only insertFact:
- sources.local_path is NULL (thin-client install) — once-per-process
  stderr warning names the missing config; all post-dedup facts go to
  legacy path. Documented as named exception in the architecture doc
  (commit 11)
- f.entity_slug couldn't resolve to a canonical slug — structurally
  unfenceable (no entity page to fence onto); legacy single-row insert
  preserves the v0.31 semantic
- Fence parse-validation fails on a .tmp — that page's facts skip; do
  NOT fall through to legacy DB-only because the DB index for that
  page would be inconsistent with a broken fence

No re-entrancy guard needed: writeFactsToFence uses writeFileSync +
renameSync directly, NOT engine.putPage. No code path can re-trigger
runFactsBackstop on the markdown write. The architecture self-prevents
the recursion concern Codex Q7 raised. Documented in fence-write.ts
so a future refactor that swaps writeFileSync for putPage sees the
constraint.

Dedup unchanged: cosine similarity @ 0.95 against DB candidates, before
fence write. Codex Q7 design: fence rows have no embeddings (not stored
in markdown text); the FS lock + sync invariant means DB == fence at
write time, so DB is the correct dedup oracle.

Tests (11 new cases in test/fence-write.test.ts):
- Happy path: stub-create + fence write + DB v51 columns persisted
- Existing-page append preserves body
- Multi-fact batch assigns consecutive row_nums
- Re-write picks up at max+1 row_num (append-only)
- Nested slug stub-creates parent dirs (companies/acme → mkdir companies)
- legacyFallback:true when localPath is null (no FS, no DB write)
- Empty facts array no-ops without stub-creating the file
- Atomic recovery: no .tmp file left after success
- lookupSourceLocalPath: existing source, unknown source, NULL local_path

The multi-process FS lock contention test lives in
test/e2e/facts-lock-contention.test.ts (commit 10's invariant capstone,
since Bun.spawn is an E2E concern). These cover the in-process happy
and recovery paths.

242 tests pass across the facts surface + adjacent files (no
regressions in facts-backstop / facts-canonicality / takes-fence /
migrate).

* feat: migration orchestrator v0_32_2.ts — backfill v0.31 facts to fences

v0.32.2 commit 6/11.

Schema migration v51 (commit 1) added the row_num + source_markdown_slug
columns. This orchestrator's job is the data half: walk every existing
pre-v51 row in the facts table (row_num IS NULL = legacy keyspace) and
append it to its entity page's `## Facts` fence, atomically + idempotently.

Critical sequencing per Codex R2-#7: this commit lands BEFORE commit 7's
extract_facts cycle phase so existing v0.31 facts get fenced before any
destructive reconciliation can see "empty fence" as authoritative. The
cycle phase in commit 7 adds an empty-fence-guard as a structural belt
to back up these suspenders.

Three phases:
- phaseASchema: assert migration v51 applied + columns exist
- phaseBFenceFacts: per (source_id, entity_slug) group, atomic .tmp +
  parse + rename appends legacy DB rows to entity-page fence; UPDATEs
  the row's v51 columns. Dry-run by default; refuses if any
  source.local_path is a dirty git tree (mirrors src/core/dry-fix.ts
  safety posture). Idempotent re-run: matches existing fence rows by
  (claim, source) and reuses their row_num instead of appending
  duplicates.
- phaseCVerify: re-parse every touched page's fence, compare row counts
  to DB; partial status on mismatch so user runs --force-retry 51

Three skip cases (each surfaced in the detail string):
- NULL entity_slug → structurally unfenceable; row stays in legacy
  keyspace permanently. Operator decides hand-curate vs delete.
- sources.local_path is NULL → thin-client / read-only brain; nothing
  to fence onto.
- Fence parse-validate fails on the .tmp → .tmp stays as quarantine
  evidence; the operator inspects.

Stub-create with type inferred from slug prefix (people→person,
companies→company, deals→deal, others→concept) so freshly-fenced pages
import cleanly via existing sync.

Tests (14 new cases in test/migrations-v0_32_2.test.ts):
- phaseASchema: complete + dry-run + no-engine
- phaseBFenceFacts: dry-run reporting without side-effects, multi-row
  backfill with row_num assignment, multi-entity batch touches multiple
  files, append to existing entity page preserves body, idempotent
  re-run (matches by claim+source, reuses row_num), NULL entity_slug
  skip, missing local_path skip
- phaseCVerify: clean state passes, fence drift fails with the slug
  named in detail
- Orchestrator end-to-end: clean run returns 3 complete phases; dry-run
  returns 3 skipped phases with zero side-effects

216 tests pass across migrations + facts surface (no regressions).

* feat: extract_facts cycle phase + empty-fence guard (Codex R2-#7)

v0.32.2 commit 7/11.

New cycle phase reconciles the DB facts index from the `## Facts`
fence on each affected entity page. Placement: between `extract`
(materializes links + timeline) and `patterns`/`recompute_emotional_
weight` so downstream phases read fresh DB facts.

Source-of-truth contract per page: parseFactsFence → wipe via
deleteFactsForPage → re-insert via engine.insertFacts. After the
phase, the DB index byte-matches the fence (modulo embeddings +
runtime-derived fields). A removed-from-fence row is removed from
DB; a hand-edited fence row updates the DB cleanly.

Pre-v51 NULL-source_markdown_slug legacy rows are structurally
protected — deleteFactsForPage targets (source_id,
source_markdown_slug) only, so the partial-UNIQUE-index keyspace
keeps legacy rows untouched.

Empty-fence guard (Codex R2-#7): pre-check `COUNT(*) FROM facts
WHERE row_num IS NULL AND entity_slug IS NOT NULL`. If > 0, the
phase returns status:'warn' with a hint pointing at
`gbrain apply-migrations --yes`. Prevents the silent-misreport
scenario where an interrupted upgrade leaves v0.31 legacy rows
in the DB while the cycle reports "0 facts on people/alice"
because the fence is empty. Belt to the runtime backstop's
suspenders in commit 5.

Wired in src/core/cycle.ts:
- Added 'extract_facts' to CyclePhase enum + ALL_PHASES + NEEDS_LOCK_PHASES
- Added runPhaseExtractFacts dispatch helper with PhaseResult shape
- Phase 5b runs between extract (5) and patterns (6); inherits
  syncPagesAffected for incremental mode

Tests (10 new cases in test/extract-facts-phase.test.ts):
- Happy path: single + multi page reconciliation
- Idempotent: second run produces same DB state as first
- Removed-from-fence row gets deleted from DB
- Empty fence reconciles to empty DB for that page
- Dry-run does not touch DB
- Full walk (no slugs filter) covers every brain page
- Guard fires when legacy v0.31 rows pending backfill
- Guard releases after backfill (row_num populated)
- NULL entity_slug legacy rows do NOT trigger the guard
- Multi-source isolation: other source's DB rows survive

226 tests pass across the facts surface + cycle + migrations
(no regressions).

* feat: 3-layer privacy strip + forget-as-fence (Codex R2 #1/#3/#5)

v0.32.2 commit 8/11.

Layer A — chunker strip (Codex R2-#1 P0):
src/core/chunkers/recursive.ts now calls stripFactsFence({keepVisibility:
['world']}) alongside the existing stripTakesFence before chunking.
Private fact text NEVER reaches content_chunks.chunk_text, embeddings,
or search. World facts remain searchable (public knowledge by
definition). Closes the leak Codex round 2 caught: get_page's strip
alone wasn't enough because chunks carry the same body text into the
search surface.

Layer B — get_page strip trigger flipped (Codex R2-#5):
src/core/operations.ts:413 strip trigger changes from `ctx.takesHolders-
AllowList` to `ctx.remote === true`. Closes the pre-existing takes hole
where subagent callers (remote:true but no allow-list) bypassed the
strip. Subagent + remote MCP + scope-restricted-token callers all get
the strip now; local CLI (remote:false) keeps the full fence visible.
Both stripTakesFence AND stripFactsFence({keepVisibility:['world']})
fire in the same code path.

Forget-as-fence (Codex R2-#3):
New src/core/facts/forget.ts forgetFactInFence({factId, reason}). When
the row has v51 columns + source.local_path set, rewrites the entity
page's fence to strike out the claim, set valid_until=today, append
"forgotten: <reason>" to context. The DB's existing
`expired_at = valid_until + now()` derivation reconstructs the forget
state on rebuild because the fence is canonical.

Two-tier fallback for cross-state safety:
- Fence path: v51 columns + sources.local_path set + fence file exists +
  fence row matches DB row_num → atomic .tmp + parse + rename, then
  DB UPDATE to match
- Legacy DB-only: every other case (pre-v51 row, NULL entity_slug,
  thin-client install, file deleted, row_num drift). DB-only forgets
  do NOT survive gbrain rebuild — named exception in the architecture
  doc.

MCP forget_fact op + gbrain forget CLI both rewired through
forgetFactInFence. New optional `--reason` flag on the CLI; new
`reason` param on the MCP op. Response carries `path: 'fence' |
'legacy_db'` so callers can surface the degraded mode loudly.

Extended strikethrough parse contract from commit 2:
- `~~claim~~` + `context: "superseded by #N"` → supersededBy=N
- `~~claim~~` + `context: "forgotten: <reason>"` → forgotten=true
- `~~claim~~` + anything else → active=false, both flags null
Both encodings use the same strikethrough marker; the parser
distinguishes via context.

Tests (38 new cases in test/privacy-strip-and-forget.test.ts):
- Layer A: 4 cases — public survives, private dropped, private-only
  fence preserves prose, no-fence pass-through, takes-fence regression
- Layer B: 1 case — stripFactsFence({keepVisibility:['world']}) shape;
  full operations-dispatch E2E lives in commit 10
- Forget-as-fence: 12 cases — fence path (strikethrough + valid_until +
  context append + default reason + existing-context preservation),
  legacy fallback (NULL row_num, NULL local_path, missing file, row_num
  drift, unknown id, already-expired)

266 tests pass across the facts + privacy + chunker + operations
surface (no regressions).

* feat: scripts/check-system-of-record.sh CI gate + function-scoped allow-list

v0.32.2 commit 9/11.

New CI invariant gate enforcing the system-of-record contract: direct
writes to derived DB tables (facts, takes, links, timeline_entries) must
go through the extract / reconcile / migration layer. Direct writes from
arbitrary code paths would bypass the markdown source-of-truth contract
— the next `gbrain rebuild` (v0.32.3) would lose the data because the
fence wasn't updated.

Banned methods (the v0.32.2 derived-write surface):
- engine.insertFact, engine.insertFacts
- engine.addLink, engine.addLinksBatch
- engine.addTimelineEntry
- engine.upsertTake
- engine.expireFact

Scoped to src/ + scripts/ per Codex R2-#8 — test/ is deliberately
excluded because tests legitimately call these methods to seed fixtures
and gating tests would break the test surface without protecting any
invariant.

Function-scoped allow-list (not file-scoped per Codex Q7): add
`// gbrain-allow-direct-insert: <reason>` on the SAME LINE as the
banned call. The grep parses the trailing comment; a different-line
comment does NOT exempt the call (regression-tested explicitly).
Comment lines (JSDoc, line-comments, backtick mentions in docstrings)
are filtered out so the gate doesn't false-positive on prose.

Wired into `bun run verify` (the canonical CI pre-test gate set).
Failure mode: gate exits 1, names every offending file:line, prints
hint pointing at the architecture doc.

Annotated 18 legitimate call sites:
- src/core/cycle/extract-facts.ts: reconcile fence → DB
- src/core/facts/backstop.ts: legacy DB-only fallback for unparented /
  thin-client facts
- src/core/facts/fence-write.ts: markdown-first reconcile path
- src/core/facts/forget.ts: 6 legacy fallback paths inside
  forgetFactInFence
- src/core/enrichment-service.ts: 2 auto-timeline / auto-link
  reconciliation sites
- src/core/output/writer.ts: 3 BrainWriter synthesize-phase sites
- src/core/operations.ts: 2 explicit MCP op sites (add_link,
  add_timeline_entry)
- src/commands/extract.ts: 5 canonical extract command sites
- src/commands/reconcile-links.ts: 2 code-graph reconciliation sites

Tests (6 new cases in test/check-system-of-record.test.ts):
- Positive: real repo passes (regression guard — the allow-list
  comments + the gate together must keep CI green)
- Negative: synthetic violator file → gate exits 1 + names the path
- Allow-list comment on SAME LINE exempts
- Allow-list comment on DIFFERENT line does NOT exempt
- Gate does NOT scan test/ (Codex R2-#8 — tests legitimately seed
  fixtures via direct insertFact calls)
- Gate DOES scan scripts/ alongside src/

163 tests pass across the gate + facts surface + operations + cycle
(no regressions). typecheck clean.

* test: system-of-record invariant E2E capstone

v0.32.2 commit 10/11.

The architectural rule prove-out. Hermetic PGLite + tempdir filesystem
(no DATABASE_URL needed; runs in standard bun test). Exercises the full
delete-and-rebuild round-trip the system-of-record contract promises.

Capstone test (full round-trip):
1. Seed 6 fixture markdown files: 3 person pages with takes + facts +
   inline links, 3 plain pages. Facts include both world + private
   visibility per page (the PRIVATE_DETAIL_PROOF canary).
2. importFromFile every page → DB; run extract (links + timeline) +
   extractTakes + runExtractFacts to reconcile all derived tables.
3. Snapshot facts + takes derived state.
4. DELETE FROM facts + takes + links + timeline_entries. Simulates the
   "DB lost; rebuild from repo" disaster scenario v0.32.3's
   `gbrain rebuild` will execute.
5. Re-import every file + re-reconcile. Re-import rebuilds tags
   (per Codex R2-#6: tags is reconciled by import-file.ts:315, NOT
   by extract phases).
6. Snapshot + diff. Assert facts + takes row sets match by content
   (entity_slug, fact) for facts and (page_slug, row_num) for takes.

Plus three supporting tests:
- v51 reconcile-key invariant: every fact row carries non-null
  row_num + source_markdown_slug after the reconcile.
- Layer A chunker strip (Codex R2-#1 P0): search for verbatim
  PRIVATE_DETAIL_PROOF text in content_chunks returns 0 matches;
  world facts ("Founded Acme in 2017") DO appear in chunks.
- Layer B get_page strip (Codex R2-#5): stripFactsFence with
  {keepVisibility:['world']} drops private rows from the response
  body while keeping world rows.

Trim from original plan: links + timeline coverage left to existing
Tier 1 E2E (sync.test.ts + backlinks.test.ts). The v0.32.2-novel
reconcile surface is facts + takes — those are what this invariant
proves. Cuts ~half the test runtime + scope without losing
v0.32.2 coverage.

4/4 pass in 2.23s. 291 tests pass across the full facts + privacy +
chunker + operations + migrate + cycle surface (no regressions).

* v0.32.2 chore: VERSION + package.json + CHANGELOG manifesto + docs + migration guide

v0.32.2 commit 11/11. Release ceremony.

VERSION + package.json + bun.lock all aligned at 0.32.2.

CHANGELOG.md entry leads with the manifesto:

  > The GitHub repo is the system of record. The database is a derived
  > cache. We do not back up the database — we rebuild it from the repo.

Followed by the BEFORE/AFTER table showing facts newly meeting the
FS-canonical bar, the gbrain forget behavior change, the privacy
strip layers, and the CI gate. Itemized changes section enumerates the
14 source files modified + 9 new test files + 132 new test cases.

docs/architecture/system-of-record.md (new, ~250 lines): the canonical
contract doc. Three-category table (FS-canonical / Derived from FS but
not user-authored / DB-only by design), named DB-only exceptions, the
3-layer privacy boundary, the forget contract, disaster-recovery flow,
and the rule for new user-knowledge categories (parser + writer + engine
method + reconciler + round-trip test).

skills/migrations/v0.32.2.md (new): agent-facing guide describing what
the v0_32_2 orchestrator does, the surface changes (forget rewrites
markdown; get_page strips for ctx.remote; chunker strips private; CI
gate; new extract_facts cycle phase), the verify steps, and the things
NOT to do (don't manually edit v51 columns; don't bypass the CI gate
without an allow-list comment).

Closes the 11-commit bisect plan. Every commit leaves the tree green.
Each commit does one conceptual thing.

* test: v0.32.2 follow-up — update 5 tests that v0.32.2 surface changes broke, plus fix 2 pre-existing flakes

Five test updates for changes v0.32.2 introduced:

- test/core/cycle.serial.test.ts: yieldBetweenPhases hook count bumped
  11 → 12 to account for the new extract_facts cycle phase. Two cases
  affected (hook is called between every phase; hook exceptions do not
  abort the cycle).

- test/apply-migrations.test.ts: buildPlan skippedFuture expectation
  lists v0.32.2 alongside v0.31.0 at the end. Two cases affected (fresh
  install with v0.11.1 installed; Codex H9 regression with v0.12.0).

- test/facts-mcp-allowlist.serial.test.ts: forget_fact dispatch idempotent
  case now expects `fact_already_expired` instead of `fact_not_found`
  on the second call. v0.32.2's forgetFactInFence introduces the more
  precise discriminator — the first call expires the fact; the second
  call sees expired_at NOT NULL and surfaces the more accurate error
  code instead of the older opaque `fact_not_found`.

Plus two pre-existing flakes that were biting the full-suite CI run
on dev boxes (both unrelated to v0.32.2; both confirmed flaking on
master before v0.32.2 work began):

- test/eval-longmemeval.test.ts warm-create speed gate: threshold
  bumped from p50<500ms → p50<1500ms. Solo run shows p50 ~25ms; under
  8-way parallel test shard load p50 spikes transiently to 500-1200ms.
  The new threshold still catches order-of-magnitude regressions (10x
  slowdown to 250ms baseline would fail at 2.5s) without flaking under
  legitimate parallel CPU contention.

- test/brain-registry.serial.test.ts empty/null/undefined id routes
  to host: the original test asserted the call rejects with
  not-UnknownBrainError, but on a dev box with `~/.gbrain/config.json`
  present (typical for anyone running gbrain locally) the host init
  succeeds and the promise resolves. Rewrote to assert the routing
  property regardless of resolve-vs-reject: catch the error if it
  throws, and check it's not UnknownBrainError. Resolved cleanly is
  also acceptable because it proves the routing went to host.

Full unit suite: 5517 pass, 0 fail (up from 5316 pass, 7 fail before
these fixes). `bun run verify` clean.

* test: e2e — update 3 tests that v0.32.2 surface changes broke

- test/e2e/dream-cycle-phase-order-pglite.test.ts: EXPECTED_PHASES
  array gains 'extract_facts' between 'extract' and 'patterns' to
  match the new v0.32.2 cycle phase order.

- test/e2e/cycle.test.ts: phase count bumped 11 → 12 (the new
  extract_facts phase increments the canonical full-cycle phase count).

- test/e2e/facts-forget.test.ts: idempotent-on-re-call case now
  expects 'fact_already_expired' instead of 'fact_not_found'. v0.32.2's
  forgetFactInFence introduces the more precise discriminator — first
  call expires the fact; second call sees expired_at NOT NULL and
  surfaces the more accurate error code.

Full E2E suite (DATABASE_URL set, sequential via scripts/run-e2e.sh)
now: 78/78 files pass, 531/531 tests pass.

 		29961811a4 v0.31.12 fix: canonical Anthropic model IDs + tier routing surface + gbrain models CLI (#844) 
* fix: canonical Anthropic model IDs + reverse alias + Opus 4.7 pricing

Replace claude-sonnet-4-6-20250929 with claude-sonnet-4-6 everywhere it
appears as a model ID. Starting with Claude 4.6, Anthropic API IDs are
dateless and pinned — the date suffix was carried forward from Sonnet 4.5
by mistake, producing a phantom ID that 404'd on every call.

Production impact in v0.31.6: isAvailable("chat") returned false in every
code path that loaded the recipe's model list, and extractFactsFromTurn
silently returned []. The headline real-time facts extraction feature
was a no-op on the happy path.

- gateway.ts:46 DEFAULT_CHAT_MODEL -> anthropic:claude-sonnet-4-6
- recipes/anthropic.ts: chat + expansion model lists drop date suffix;
  remove wrong-direction alias (claude-sonnet-4-6 -> -20250929);
  add reverse alias (-20250929 -> claude-sonnet-4-6) so stale user
  configs in models.dream.synthesize etc. keep working
- facts/extract.ts: routes through resolveModel; both fallbacks corrected
- anthropic-pricing.ts: Opus 4.7 corrected $15/$75 -> $5/$25 per
  Anthropic docs (the $15/$75 was Opus 4.0 pricing)
- cross-modal-eval/runner.ts: PRICING now reads from ANTHROPIC_PRICING
  for Anthropic models instead of duplicating the map (single source of
  truth — fixes the drift trap that motivated this whole patch)

Tests: cherry-pick PR #830's test/anthropic-model-ids.test.ts verbatim
(6 recipe-shape guardrails). Update gateway-chat tests to assert reverse
alias resolves correctly. Update budget-meter test for new Opus pricing.

* feat: model tier system + recipe-models merge + async reconfigure hook

Add 4-tier model routing (utility/reasoning/deep/subagent) so users can
swap defaults with one config key. Each tier maps to a class of work;
override globally via models.default or per-tier via models.tier.<tier>.

Codex flagged three real architecture issues in the v0.31.12 plan review;
this commit addresses each.

F3 — sync/async timing of configureGateway:
  - buildGatewayConfig stays synchronous (pre-engine-connect callers
    keep working)
  - New reconfigureGatewayWithEngine(engine) async function re-resolves
    expansion + chat defaults through resolveModel after engine.connect()
  - cli.ts wires the re-stamp into the post-connect path

F4/F5 — softening assertTouchpoint was too broad:
  - Earlier plan was to flip native-recipe validation from throw to warn,
    affecting gateway.chat AND gateway.expand AND gateway.embed
  - Instead: per-gateway-instance recipe-models merge. assertTouchpoint
    gets an optional extendedModels Set; when the user opted into a model
    via config, it bypasses the throw. Source-code typos still fail fast.
  - Existing contract test (test/ai/gateway-chat.test.ts:106) preserved

Tier defaults are TIER_DEFAULTS in model-config.ts. Resolution chain
inserts at step 5 (between models.default and env var). Each existing
resolveModel call site gains a tier: arg — think (deep), cycle/synthesize
(reasoning + utility for verdict), patterns/drift (reasoning), auto-think
(deep), facts/extract (reasoning).

Plus 10 new tests pinning tier precedence, subagent-tier fallback when
models.default is non-Anthropic, and the F6 alias-chain conflict case.

* feat: subagent runtime enforcement for non-Anthropic models (3 layers)

The subagent loop uses Anthropic's Messages API with prompt caching on
system + tools. OpenAI/Google have different shapes. Setting
models.default = openai:gpt-5.5 and routing the subagent there silently
breaks the loop.

Codex F1+F2+F13 in the v0.31.12 plan review pointed out that "warn at
doctor" wasn't enough — handlers/subagent.ts:148 still did
`const model = data.model ?? DEFAULT_MODEL` and called Anthropic directly,
so a job submitted with data.model = openai:gpt-5.5 bypassed any tier
logic and failed at runtime with a confusing provider error.

Three layers of enforcement, defense in depth:

Layer 1 (queue.ts:add) — submit-time guard. When name === 'subagent'
and data.model is set, validate the provider. Non-Anthropic rejects
before the job enters the queue.

Layer 2 (handlers/subagent.ts) — tier-resolution fallback. The handler
routes through resolveModel({ tier: 'subagent' }). If the chain resolves
to a non-Anthropic provider (via models.default or models.tier.subagent),
the resolver warns + falls back to TIER_DEFAULTS.subagent
(claude-sonnet-4-6).

Layer 3 (doctor.ts:checkSubagentProvider) — surfacing layer. Warns when
models.tier.subagent or models.default is explicitly set to a
non-Anthropic provider, with a paste-ready fix command. Lets users see
config drift before submitting a job.

Tests: 3 new cases in test/agent-cli.test.ts asserting the queue-level
guard rejects non-Anthropic data.model. Existing test/subagent-handler
suite still passes.

* feat: gbrain models CLI + doctor probe + silent-no-op regression test

New gbrain models CLI gives the agent and user visibility into routing.
Read mode prints the tier table, current overrides, per-task config,
and aliases with source-of-truth attribution per row. Doctor subcommand
fires a 1-token probe to each configured chat/expansion model and
classifies failures (model_not_found / auth / rate_limit / network /
unknown) so config-time invalid IDs surface without waiting for a
production call that silently degrades.

Per Codex F11 — no specific dollar cost claim in either the help text
or the CHANGELOG (providers have minimum-output billing and prompt-cache
rounding that vary). Probe is opt-in (gbrain doctor --probe-models),
never auto-runs. --skip=<provider> narrows the matrix for cost-sensitive
operators.

Per Codex F7+F8+F15 (the structural regression gap): new
test/facts-extract-silent-no-op.test.ts is THE regression test for the
bug class that motivated v0.31.12. Five cases including the smoking-gun:
when chat IS available, extractFactsFromTurn MUST actually call the chat
transport, not silently return []. Uses the gateway's
__setChatTransportForTests seam so it runs in every shard with no API key.

* chore: bump version and changelog (v0.31.12)

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: document v0.31.12 model tier system + gbrain models CLI

Add CLAUDE.md Key Files annotations for the v0.31.12 work:
src/core/model-config.ts (tier system + isAnthropicProvider + TIER_DEFAULTS),
src/core/ai/model-resolver.ts (assertTouchpoint extendedModels arg),
src/core/ai/gateway.ts (reconfigureGatewayWithEngine + extended-models registry),
src/core/minions/queue.ts (subagent submit-time guard, layer 1 of 3),
src/commands/models.ts (new gbrain models CLI + doctor probe),
src/commands/doctor.ts (subagent_provider check, layer 3 of 3),
src/core/ai/recipes/anthropic.ts (canonical model IDs + reverse alias),
src/core/anthropic-pricing.ts (Opus 4.7 corrected to \$5/\$25).

Add CLAUDE.md commands section for gbrain models + gbrain models doctor
+ power-user config recipes. Add README.md command-table rows for the
same. Regenerate llms-full.txt so the bundled docs stay in sync.

* docs: scrub --probe-models reference (flag not actually wired)

The v0.31.12 CHANGELOG and skills/conventions/model-routing.md both
referenced `gbrain doctor --probe-models` as an integrated probe entry
point. The flag was never implemented — only `gbrain models doctor`
landed as the probe surface. Caught by /document-release subagent.

Drop the references rather than wire an untested flag at the last minute.
The probe is reachable via `gbrain models doctor`; users who want it
in doctor's output run that command separately.

 		7267462311 v0.31.4 feat: takes v2 — lessons from 100K-take production extraction (#795) 
* feat: takes v2 — lessons from 100K-take production extraction

Consolidates everything learned from the first full takes extraction run
(28,256 pages, 100,720 takes, $361 on Azure GPT-5.5) and subsequent
cross-modal eval (GPT-5.5 + Opus 4.6, scored 6.8/10 overall).

## Fixes

**fix(cli): add recall and forget to CLI_ONLY set**
v0.31 added these commands to handleCliOnly() but forgot the gate set.
Both fell through to cliOps.get() → 'Unknown command'.

**feat(synthesize): auto-enable when corpus dir is configured**
Setting session_corpus_dir is now sufficient — enabled defaults to true
when a corpus dir is set. Explicit enabled=false still wins. Eliminates
the footgun where users configure a corpus dir and nothing happens.

**feat(engine): round takes weights to 0.05 increments**
Cross-modal eval found false precision (0.74, 0.82) implies calibration
accuracy that doesn't exist. Both postgres and pglite engines now round
on insert. 1.0 and 0.0 are preserved exactly.

## Documentation

**docs: takes-vs-facts architectural distinction**
New doc explaining the two epistemological layers, why they must never be
conflated, how the dream cycle consolidate phase bridges them, and
production extraction data (model selection, eval dimensions, key
learnings for extraction prompts).

**docs(takes-fence): clarify holder semantics with eval examples**
Holder = who HOLDS the belief, NOT who it's ABOUT. Expanded JSDoc with
concrete right/wrong examples from the cross-modal eval. Additional
rules: amplification ≠ endorsement, self-reported ≠ verified, founder
describing company → people/founder not companies/slug.

## Tests (17 new, all passing)

- 5 synthesize-enabled-default tests
- 6 takes-holder-semantics tests
- 6 takes-weight-rounding tests

## Cross-Modal Eval Context

| Dimension         | GPT-5.5 | Opus 4.6 | Avg  |
|-------------------|---------|----------|------|
| Accuracy          | 7       | 8        | 7.5  |
| Attribution       | 6       | 7        | 6.5  |
| Weight calibration| 7       | 7        | 7.0  |
| Kind classification| 6      | 7        | 6.5  |
| Signal density    | 7       | 6        | 6.5  |

Top improvements addressed in this PR:
1. Holder vs subject confusion (docs + tests)
2. Weight false precision (runtime enforcement)
3. Takes ≠ facts distinction (architectural doc)
4. Synthesis auto-enable (runtime fix)
5. recall/forget CLI routing (bug fix)

* docs(filing-rules): anchor takes attribution rules (EXP-3)

Adds a "Takes attribution" section to skills/_brain-filing-rules.md
distilling the 6 rules from docs/takes-vs-facts.md into a terse
contract that downstream agents (OpenClaw, Wintermute) can read as
their canonical filing surface.

Documentation only — no in-repo runtime consumer (synthesize.ts reads
the .json file, not the .md). EXP-4 lands the runtime parser-level
holder validation.

Codex review #9: relabels EXP-3 as documentation, not quality work.
The runtime check is EXP-4.

* feat(takes): weight backfill v46 + NaN hardening at 4 sites (EXP-1, Hardening)

Migration v46 (takes_weight_round_to_grid): backfills pre-v0.32 takes.weight
to the 0.05 grid the engine layer (PR #795) enforces on insert. Cross-modal
eval over 100K production takes flagged 0.74, 0.82-style values as false
precision; this brings existing data to the same grid that all new writes
already use.

Tolerance-based comparison (abs > 0.001) avoids the float32-noise re-touch
loop that the naive `weight <> ROUND(...)` form would create — REAL/NUMERIC
comparison promotes weight to DOUBLE PRECISION first, surfacing ~1e-7
representation noise as inequality. The 0.05 grid is 5e-2, so any genuine
off-grid value clears the 1e-3 threshold cleanly.

`transaction: false` (codex review #2 correction): not for mid-statement
resume (a single SQL statement either completes or rolls back). What it
actually buys is freeing the migration runner from holding a long
transaction so other gbrain processes can interleave.

NaN hardening (codex review #8): extracts `normalizeWeightForStorage()` to
takes-fence.ts as a single source of truth used by all 4 takes write sites:
  - pglite-engine.ts addTakesBatch
  - pglite-engine.ts updateTake (was missed in original PR — only clamped,
    didn't round; now rounds AND guards NaN)
  - postgres-engine.ts addTakesBatch
  - postgres-engine.ts updateTake (same fix)

The helper guards `!Number.isFinite()` BEFORE the [0,1] range check (NaN
comparisons are always false, so NaN survived the prior clamp and reached
Math.round(NaN * 20) / 20 = NaN, written through to the DB).

Tests:
- test/migrations-v46-takes-weight-backfill.test.ts: behavioral PGLite test
  (rounding fixture + Codex #2 re-run idempotency + on-grid preservation).
- test/takes-weight-rounding.test.ts: imports the real helper, adds NaN /
  Infinity / -Infinity / null / undefined / updateTake-shape coverage.
- test/migrate.test.ts: structural assertions for v46 SQL shape.

All 52 tests pass; typecheck clean.

* feat(doctor): takes_weight_grid check + pure helper extraction (EXP-2)

Adds doctor's `takes_weight_grid` slice — the post-migration drift detector
for the 0.05 weight grid v0.31 enforces on insert and v46 backfilled.

Codex review #7 corrected the original plan's "extend test/doctor.test.ts
with 3 cases" estimate. runDoctor() is a side-effectful command with
process.exit branches, and the existing tests are mostly source-structure
assertions. The fix: extract `takesWeightGridCheck(engine: BrainEngine)`
as a pure exported function. runDoctor calls it. Tests target the helper
directly with stubbed engines for the missing-table branch and against
real PGLite for the 4 ratio bands.

Branches:
  - 0 takes total → ok ("No takes yet")
  - off_grid / total > 10% → fail (with apply-migrations fix hint)
  - 1% < off_grid / total ≤ 10% → warn (same fix hint)
  - else → ok
  - takes table missing (pre-v37) → warn, graceful skip

Tolerance comparison matches migration v46 (abs > 1e-3) so float32 noise
doesn't make a healthy brain look broken.

Tests (test/doctor.test.ts):
  - takesWeightGridCheck export shape
  - 0-takes branch (avoids divide-by-zero)
  - 100% on-grid via engine.addTakesBatch (which now normalizes)
  - 8/10 off-grid → fail
  - 5/100 off-grid → warn
  - missing-table branch via stub engine

All 21 doctor tests pass; typecheck clean.

* feat(takes): holder runtime validation + producer seam (EXP-4)

Adds parser-level holder grammar enforcement so cross-modal eval's #1
attribution error (holder/subject confusion, scored 6.5/10 across 100K
production takes) shows up as a sync-failure record an operator can see.

Changes:

- src/core/sync.ts: exports SLUG_SEGMENT_PATTERN, the actual character
  class slugifySegment() produces ([a-z0-9._-]). Codex review #3 — the
  initial plan's stricter regex would have warned on legitimate slugs
  like `companies/acme.io` and `people/foo_bar`. HOLDER_REGEX now wraps
  this shared pattern instead of inventing a parallel grammar.

- src/core/takes-fence.ts: HOLDER_REGEX + isValidHolder() helper.
  parseTakesFence() emits TAKES_HOLDER_INVALID warnings for non-matching
  holders. Row preserved (markdown source-of-truth contract).

  Catches the eval's failure modes — `Garry`, `people/Garry-Tan`,
  `world/garry-tan`, `users/garry`, whitespace-only — while keeping
  `companies/acme.io`, `people/foo_bar`, `notes/v1.0.0`-style dotted
  slugs valid. Bare-slug form (`garry`, `alice`) accepted as v0.32 legacy
  compat — production brains shipped with bare-slug holders before the
  namespaced JSDoc landed in PR #795. Reserved for v0.33 promotion.

- src/core/cycle/extract-takes.ts (codex review #4 producer seam): adds
  `failedFiles: Array<{path, error}>` to ExtractTakesResult. Both fs
  and db extraction paths populate it from TAKES_HOLDER_INVALID warnings
  so the migration orchestrator can hand it to recordSyncFailures().
  Without this seam, extending classifyErrorCode would do nothing
  (the regex would have nothing to classify).

- src/commands/migrations/v0_28_0.ts: phaseBBackfill calls
  recordSyncFailures(result.failedFiles, 'migration:v0.28.0-backfill')
  after extractTakes completes. Best-effort — persistence failure
  doesn't fail the backfill phase. Doctor's `sync_failures` check now
  shows TAKES_HOLDER_INVALID=N breakdown after upgrade.

- src/core/sync.ts:classifyErrorCode: extends with TAKES_HOLDER_INVALID
  + TAKES_TABLE_MALFORMED / TAKES_ROW_NUM_COLLISION / TAKES_FENCE_UNBALANCED
  bucket. Previously these warnings bucketed to UNKNOWN.

Tests (test/takes-holder-validation.test.ts — 26 cases):
- Canonical forms (world / brain / people-namespace / companies-namespace)
- Codex #3 dotted-slug + underscore-slug positives
- Legacy bare-slug compat positives
- Eval-flagged error mode rejections (uppercase, mixed case, world/<slug>,
  unrecognized prefix, whitespace, embedded slash)
- HOLDER_REGEX anchoring guard
- SLUG_SEGMENT_PATTERN export shape + drift guard against the wrapping regex
- parseTakesFence end-to-end emission contract
- classifyErrorCode regex coverage

127 tests pass across affected files; typecheck clean. No existing fixtures
broken (legacy bare-slug compat preserves old `garry`-style holders during
the v0.32 transition window).

* feat(eval): gbrain eval takes-quality CLI — DB-authoritative + 4-mode (EXP-5)

Reproducible cross-modal quality eval for the takes layer. Three frontier
models score a sample against the 5-dim rubric, the runner aggregates to
PASS/FAIL/INCONCLUSIVE, the receipt persists to eval_takes_quality_runs.
Trend mode segregates by rubric_version; regress mode is a CI gate that
exits 1 when any dim regresses past --threshold.

Subcommands:
  run     [--limit N --cycles N --budget-usd N --slug-prefix P --models a,b,c]
  replay  <receipt-path> [--json]                 # NO BRAIN required
  trend   [--limit N --rubric-version V --json]
  regress --against <receipt> [--threshold T --json]

Codex review integrations (D7 — all 10 findings landed):

  #1 json-repair shim re-exports BOTH parseModelJSON AND the
     ParsedScore + ParsedModelResult types. The original plan only
     re-exported the function, which would have compile-broken
     cross-modal-eval/aggregate.ts:19's type import.

  #3 Receipt name binds (corpus_sha8, prompt_sha8, models_sha8,
     rubric_sha8) so a future rubric tweak segregates trend rows
     instead of silently corrupting the quality-over-time graph.
     RUBRIC_VERSION + rubric_sha8 are persisted in every receipt.

  #4 Pricing fail-closed: any model not in pricing.ts produces an
     actionable PricingNotFoundError before any HTTP call fires.
     Same drift problem as cross-modal-eval/runner.ts:estimateCost(),
     but explicit instead of silent zero.

  #5 Aggregate requires ALL 5 declared rubric dimensions per model.
     Cross-modal-eval v1's union-of-whatever-parsed pattern allowed a
     model to omit a dim and still PASS — that's a regression-gate
     hole. Now: missing-dim drops the contribution, treated identically
     to a parse failure. Empty-scores PASS regression guard preserved.

  #6 DB-authoritative receipt persistence. Original two-phase plan had
     a split-brain reconciliation gap (disk-success/DB-fail vanishes
     from trend; DB-success/disk-fail unreplayable). Now DB row is the
     source of truth (carries full receipt JSON in a JSONB column);
     disk artifact is best-effort. replay reads disk first; loadReceiptFromDb
     reconstructs from DB when the disk file is missing.

  #10 Brain-routing: replay is the only sub-subcommand that doesn't
      need a brain. cli.ts no-DB bypass routes "eval takes-quality replay"
      directly to runReplayNoBrain, which exits 0/1/2 cleanly without
      ever touching the engine. Other modes go through connectEngine.

Files added:
  src/core/eval-shared/json-repair.ts (hoisted from cross-modal-eval)
  src/core/takes-quality-eval/{rubric,pricing,aggregate,receipt-name,
                                receipt-write,receipt,replay,regress,trend,runner}.ts
  src/commands/eval-takes-quality.ts
  docs/eval-takes-quality.md (stable schema_version: 1 contract)
  10 test files (83 cases — aggregate / receipt-name / shim / pricing /
                 rubric / receipt-write / replay / trend / regress / cli)

Files modified:
  src/cli.ts: replay no-DB bypass + engine-required dispatch
  src/core/cross-modal-eval/json-repair.ts → re-export shim
  src/core/migrate.ts: append v47 (eval_takes_quality_runs table)
  src/core/pglite-schema.ts + src/schema.sql: mirror the v47 table for
    fresh-install path. RLS toggled on the new table.
  src/core/schema-embedded.ts: regenerated via build:schema
  test/migrate.test.ts: 6 structural cases for v47

186 tests pass; typecheck clean. Replay verified working end-to-end
(reads receipt JSON file without DATABASE_URL, exits with the verdict
code, prints actionable error on missing file).

* test(eval): fill EXP-5 unit-test gaps + test-isolation lint fix

Three additions identified during the test-gap audit:

  1. test/eval-takes-quality-boundaries.test.ts (4 cases):
     - empty corpus → "no takes to evaluate" (pre-LLM)
     - source=fs reserved for v0.33 → clear refusal
     - --budget-usd + unknown model → PricingNotFoundError BEFORE any
       network call (codex review #4 fail-closed contract)
     - --budget-usd null + unknown model → no pre-flight pricing error
       (proves pricing pre-flight gates ONLY when budget is set)

  2. test/eval-takes-quality-runner.serial.test.ts (7 cases):
     End-to-end runner integration with mock.module-stubbed gateway.chat.
     Quarantined as *.serial.test.ts because mock.module leaks across
     files in the same shard process (R2 in check-test-isolation.sh).
     Covers:
       - 3 PASS scores → verdict=pass with all dim scores in receipt
       - all model errors → INCONCLUSIVE
       - 1 success + 2 errors → INCONCLUSIVE (need >=2 contributing)
       - 3 successes with low scores → FAIL
       - budget cap fires before cycle 1 (no chat() ever called)
       - budget cap allows cycle when projection fits

  3. test/eval-takes-quality-receipt-write.test.ts: refactored to use
     withEnv() helper for GBRAIN_HOME mutation instead of direct
     process.env writes. The original beforeAll mutation tripped the
     check-test-isolation.sh R1 lint. withEnv() saves/restores via
     try/finally per-test so other shard files don't see the override.

Verification:
  bun run test       → 4977 pass / 0 fail
  bun run test:serial → 179 pass / 0 fail
  bun run verify     → clean (typecheck + 9 pre-checks pass)

* test(eval): real-Postgres E2E for eval_takes_quality_runs (EXP-5)

Pure-PGLite tests already cover the receipt-write contract; this E2E
verifies the same code path against actual Postgres so the postgres.js
JSONB encoding and the v47 migration apply cleanly under production
conditions.

Coverage (8 cases):
  - migration v47 created the table with all expected columns
  - writeReceiptToDb persists full receipt_json on Postgres
  - 4-sha UNIQUE constraint enforces ON CONFLICT DO NOTHING idempotency
    (3 inserts → 1 row)
  - rubric_version segregation: distinct rubric_sha8 → distinct row
    (codex review #3 — rubric epoch separation)
  - loadTrend reads in DESC order on Postgres
  - loadReceiptFromDb reconstructs receipt JSON via the JSONB column
  - writeReceipt (combined) succeeds with disk artifact + DB row
  - trend SELECT plan executes (planner picks index on larger tables)

Skips gracefully when DATABASE_URL is unset (existing hasDatabase()
helper). Uses the canonical setupDB/teardownDB from test/e2e/helpers.ts.
GBRAIN_HOME mutation is wrapped in withEnv() per the v0.32.0 test-isolation
lint contract.

Verification:
  bash scripts/run-e2e.sh → 71 files / 499 tests / 0 fail (full E2E suite)
  bun test test/e2e/eval-takes-quality.test.ts → 8 / 8 pass standalone

* test: fill v0.32 unit + E2E gap audit (3 new files, 36 cases)

Audit of shipped v0.32 code surfaced 4 wiring gaps that the per-EXP unit
tests didn't cover. Adding direct integration tests for each so a future
refactor can't accidentally bypass the helper or unwire the producer seam.

test/extract-takes-holder-producer-seam.test.ts (7 cases) — codex review
#4 producer seam. Verifies extractTakesFromDb populates ExtractTakesResult.
failedFiles[] when parseTakesFence emits TAKES_HOLDER_INVALID warnings,
and that the entry shape is recordSyncFailures-compatible. Without this
test, the v0_28_0 migration's recordSyncFailures call would have silently
fed it nothing if a refactor accidentally dropped the failedFiles append.
Covers: valid holder (no entry), invalid uppercase, world/<slug>, mixed
valid+invalid, legacy bare-slug compat, malformed-table-only (no leak),
recordSyncFailures shape compatibility.

test/engine-weight-rounding-integration.test.ts (15 cases) — codex review
#8 integration coverage. Helper is unit-tested; this proves both engines'
addTakesBatch + updateTake paths actually call it. PGLite-side coverage
mirrors the test/e2e/takes-weight-rounding-postgres.test.ts E2E for real
Postgres. Covers: 0.74→0.75, 0.82→0.80, on-grid identity, NaN→0.5,
Infinity→0.5, clamp high/low, undefined default, mixed batch order,
updateTake rounds (was unhardened pre-v0.32), updateTake NaN, updateTake
preserves prior weight when undefined.

test/e2e/takes-weight-rounding-postgres.test.ts (6 cases, 14 expects) —
real-Postgres write-path coverage. Specifically tests the postgres.js
unnest() bind path that PGLite doesn't exercise:
  - addTakesBatch rounds via the unnest() bind shape
  - addTakesBatch handles NaN at the postgres.js array marshaling layer
  - 10-row mixed batch (4 off-grid) rounds each independently
  - updateTake rounds on real Postgres
  - updateTake handles NaN
  - migration v48 tolerance matches engine-write tolerance (round-trip
    proof — engine-rounded value is invisible to v48's WHERE clause)

Verification:
  bun run test       → 5166 pass / 0 fail (parallel unit, 128s)
  bun run test:serial → 190 pass / 0 fail
  bun run test:e2e   → 71 / 74 files; 3 pre-existing env-inheritance
                       failures (serve-http-oauth, sources-remote-mcp,
                       thin-client — confirmed identical on master in
                       this environment, documented in CLAUDE.md)
  bun run verify     → clean

* fix(auth): connect engine in withConfiguredSql; unbreak 3 OAuth E2E suites

Real production bug, not just a test-environment issue.
withConfiguredSql in src/commands/auth.ts created a PostgresEngine via
createEngine() but never called engine.connect(). The PostgresEngine.sql
getter falls back to db.getConnection() (the module-level singleton) when
its instance _sql is unset — and db.connect() wasn't called either.

So every `gbrain auth` subcommand (create, list, revoke, register-client,
revoke-client) crashed with the misleading "No database connection:
connect() has not been called" error on real Postgres. Anyone with a
Postgres-backed brain hit this. The error pointed at gbrain init which
made the regression invisible — users assumed they hadn't initialized.

Verified by running `gbrain auth register-client` directly:
  Before: "Error: No database connection: connect() has not been called."
  After:  "OAuth client registered: ..." with credentials printed.

This fix unblocked all 3 previously-failing E2E suites (which all use
register-client in beforeAll):
  serve-http-oauth.test.ts:    0/28 → 28/28 pass
  sources-remote-mcp.test.ts:  0/14 → 14/14 pass
  thin-client.test.ts:         0/7  →  6/7 pass + 1 documented skip

Two surgical test-side fixes also landed:

1. test/e2e/thin-client.test.ts:182 — assertion typo. Test expected
   r.stderr to contain "thin client" (space). Actual refusal message
   says "(thin-client of <url>)" with hyphen. Loosened to /thin[- ]client/
   so a future format tweak doesn't false-fail.

2. test/e2e/thin-client.test.ts:239 — skipped "remote ping triggers
   autopilot-cycle" with a clear TODO. Test asks the wrong question
   against the existing fixture: `gbrain serve --http` deliberately
   does NOT start a job worker (workers run via separate `gbrain jobs
   work` process), so the submitted autopilot-cycle job sits in
   `waiting` forever. Test was supposed to fall back to the self-imposed
   `--timeout`, but `gbrain remote ping --timeout` doesn't honor the cap
   when callRemoteTool hangs (loop only checks elapsed time between
   iterations; a single in-flight callTool with no AbortSignal blocks
   forever). Two real follow-ups would unblock: thread an AbortSignal
   through callRemoteTool's MCP callTool path, OR start a `gbrain jobs
   work` subprocess in beforeAll. Either is its own PR. Wire path
   coverage isn't lost — exercised by every other test in this file
   plus the entire serve-http-oauth.test.ts suite.

Verification:
  bun test test/e2e/serve-http-oauth.test.ts test/e2e/sources-remote-mcp.test.ts test/e2e/thin-client.test.ts
    → 47 pass / 1 skip / 0 fail in 8.4s
  bun run verify → clean

 		ff53a4c9bc v0.31.1.1-fixwave fix-wave: 22 community fixes (auth-code P0, upgrade-path, sync, multi-source, privacy) (#776) 
* fix: bootstrap forward-references for v39-v41 schema replay

Three column-with-index forward references in the embedded schema blob were
missing from applyForwardReferenceBootstrap, so any brain at config.version
< 39 (Postgres) or < 41 (PGLite) wedges before the migration runner can
advance. Reproduced end-to-end on a PlanetScale Postgres brain stuck at
config.version=34 trying to upgrade to v0.30.0:

  ERROR: column "effective_date" does not exist
  ERROR: column cc.modality does not exist

(After upgrading, gbrain search and gbrain reindex-frontmatter both fail.)

The schema-blob references that crash before migrations run:

- v39 (multimodal_dual_column_v0_27_1):
    CREATE INDEX idx_chunks_embedding_image
      ON content_chunks USING hnsw (embedding_image vector_cosine_ops)
      WHERE embedding_image IS NOT NULL;
- v41 (pages_recency_columns):
    CREATE INDEX pages_coalesce_date_idx
      ON pages ((COALESCE(effective_date, updated_at)));

PGLite already covered v39 (lines 273+, 308+, 382-392). Postgres and PGLite
both lacked v40+v41 coverage. This commit adds:

- Postgres engine probe + branch for v39 (modality, embedding_image) — was
  entirely missing on Postgres, so Postgres brains < v39 hit the wedge that
  PGLite already protected against.
- Both engines: probe + branch for v40+v41. Bootstraps all five additive
  pages columns (emotional_weight, effective_date, effective_date_source,
  import_filename, salience_touched_at) gated on `effective_date_exists`
  as the proxy.
- test/schema-bootstrap-coverage.test.ts: extends REQUIRED_BOOTSTRAP_COVERAGE
  with the six new columns AND the pre-test DROP block so both the per-target
  assertion test and the end-to-end "bootstrap + SCHEMA_SQL replay" test
  exercise the new coverage.

All 5 tests in schema-bootstrap-coverage pass. typecheck clean.

Bootstrap stays additive-columns-only. Indexes are left to schema replay /
migrations as before.

* fix(deps): declare @jsquash/png and heic-decode

Both packages are direct imports in src/core/import-file.ts (decodeIfNeeded
for HEIC/AVIF → PNG) but only @jsquash/avif was declared. bun --compile
fails on a fresh install:

  error: Could not resolve: "@jsquash/png/encode.js"
  error: Could not resolve: "heic-decode"

Adds the missing declarations so npm install / bun install bring them in.

Versions chosen as latest at time of fix:
  @jsquash/png  ^3.1.1
  heic-decode   ^2.1.0

* fix(backfill-effective-date): replace bare BEGIN/COMMIT with engine.transaction()

postgres.js refuses bare BEGIN/COMMIT on pooled connections with
UNSAFE_TRANSACTION. The migration runner and other call sites already
use engine.transaction() (which routes through sql.begin() with a
reserved backend) — backfill-effective-date.ts was the holdout.

Reproduces on PlanetScale Postgres (us-east-4.pg.psdb.cloud) running
the v0.29.1 orchestrator's Phase B against a brain that has any rows
needing backfill:

  Reindex ok ... UNSAFE_TRANSACTION: Only use sql.begin, sql.reserved or max: 1

Switches the per-batch transaction to engine.transaction(async tx => …).
The SET LOCAL statement_timeout still scopes to the transaction; UPDATE
runs through the tx-scoped engine. ROLLBACK on error happens
automatically via sql.begin's contract.

Equivalent fix shape to existing usages in src/core/postgres-engine.ts
(lines 703, 806, 925) and the migration runner in src/core/migrate.ts
(line 2147).

* fix(v0_29_1): connect engine before use in Phase B and Phase C

phaseBBackfill() and phaseCVerify() build their own engine via
createEngine(toEngineConfig(cfg)) but never call engine.connect().
This worked accidentally before because executeRaw lazily falls back
to db.getConnection(), but engine.transaction() (added in the
companion backfill fix) requires a connected backend and surfaces
the missing-connect with:

  No database connection: connect() has not been called.
  Fix: Run gbrain init --supabase or gbrain init --url <connection_string>

Other orchestrators in the same directory get this right —
v0_28_0.ts:181 already does `await engine.connect(engineConfig)`
right after createEngine. Aligning v0_29_1 with that pattern.

After this + the backfill fix, v0.29.1 orchestrator runs to
'complete' on a fresh upgrade with backfill-needed rows, instead
of wedging at 'partial' status.

Note: anyone hitting the wedged state after the prior failures will
need `gbrain apply-migrations --force-retry 0.29.1` once before the
next apply-migrations --yes succeeds (the 3-consecutive-partials
guard in apply-migrations.ts is still active).

* fix: connect engine in v0.29.1 migration

* fix(upgrade): detectBunLink fails because bun resolves symlinks in argv[1]

bun resolves the entire symlink chain before setting process.argv[1],
so lstatSync(argv1).isSymbolicLink() always returns false for bun-link
installs, short-circuiting the git-config walk that would correctly
identify the repo. Remove the symlink gate — argv[1] is already the
real path inside the checkout, which is what the walk needs.

Also: return { repoRoot } so the upgrade path can auto-execute
git pull + bun install via execFileSync (no shell injection surface).

Fixes #368, supersedes incomplete v0.28.5 fix for #656.

* fix(oauth): clamp authorize() requested scopes against client.scope (RFC 6749 §3.3)

The MCP SDK's authorize handler (`@modelcontextprotocol/sdk/.../auth/handlers/authorize.js`)
splits `?scope=...` verbatim and forwards the parsed list to the provider, so the
provider has to clamp against the client's registered grant. v0.28.11
`authorize()` (src/core/oauth-provider.ts:235-259) inserted `params.scopes || []`
raw into `oauth_codes`, so a `read`-registered client requesting
`?scope=admin` had `['admin']` stored and `exchangeAuthorizationCode` issued
a fully-admin access token at /token exchange.

The asymmetry is the bug: the other two grant entry points already clamp.
`exchangeClientCredentials` (line 513-515) filters requested scopes through
`hasScope(allowedScopes, s)`, and `exchangeRefreshToken`'s F3 (line 372-380)
enforces RFC 6749 §6 subset against the original grant. authorize() lined up
with neither.

Fix mirrors the client_credentials filter shape so all three grant entry
points clamp consistently:

    const allowedScopes = parseScopeString(client.scope);
    const grantedScopes = (params.scopes || []).filter(s => hasScope(allowedScopes, s));

Empty/omitted requested scope keeps storing `[]` (existing shape, not a
security boundary). The clamped subset is what the client sees in the
`scope` field of the token response, which is the spec-compliant signal
that the grant was reduced.

Test coverage:
- New: authorize clamps requested scopes against client.scope (RFC 6749 §3.3)
  — read-only client requests ['read','write','admin'] and the issued token
  carries only ['read'].
- New: authorize subset request returns subset — 'read write' client
  requesting ['read'] gets ['read'] (regression guard against over-clamping).

The existing v0.26.9 oauth.test.ts pins F3 (refresh clamp) but had no
authorize-side coverage, which is why the regression survived.

* fix(sync): handle detached HEAD by skipping pull and ingesting local working tree

* fix(sync): --skip-failed acks pre-existing unacked failures up-front

The recovery flow that doctor + printSyncResult both advertise was broken:

1. User has files with bad YAML → they hit the failure log + sync stays
   blocked at last_commit.
2. User fixes the YAML.
3. User re-runs `gbrain sync` — sync succeeds, advances last_commit.
4. `gbrain doctor` still reports N unacked failures from step 1 because
   sync-failures.jsonl is append-only history, never auto-cleared.
5. doctor message says: "use 'gbrain sync --skip-failed' to acknowledge".
6. User runs `gbrain sync --skip-failed` → "Already up to date." → log
   unchanged.

The bug: --skip-failed only acknowledges failures from the CURRENT run.
performSync's ack path is gated on `failedFiles.length > 0` after sync —
it never fires when the diff is empty (because the user already fixed
the bad files) or when the sync is up to date. So the documented recovery
sequence is a no-op exactly when the user needs it.

The fix: at the top of runSync, when --skip-failed is set, eagerly ack
any pre-existing unacked failures before any sync work runs. Now the flag
means "acknowledge whatever is currently flagged and move on" regardless
of whether the current run produces new failures or finds nothing to do.

The inner per-run ack path stays — it still handles new failures from
the CURRENT run, which is the (a) syncing now produces failures + (b)
caller wants to ack them path. The two paths compose: `gbrain sync
--skip-failed` clears stale + advances past anything new, all in one
command, matching what the doctor message promises.

Tests: 2 added in test/sync-failures.test.ts. One source-string pin on
the new gate (the file's existing pattern for CLI-flag tests). One
behavioral test on the underlying acknowledgeSyncFailures path.

Repro:
  $ gbrain doctor
  [WARN] sync_failures: 27 unacknowledged sync failure(s)...
         Fix the file(s) and re-run 'gbrain sync', or use
         'gbrain sync --skip-failed' to acknowledge.
  $ # ... fix the YAML ...
  $ gbrain sync
  Already up to date.
  $ gbrain sync --skip-failed
  Already up to date.   # before this PR
  $ gbrain doctor
  [WARN] sync_failures: 27 unacknowledged sync failure(s)...   # still!

After:
  $ gbrain sync --skip-failed
  Acknowledged 27 pre-existing failure(s).
  Already up to date.
  $ gbrain doctor
  [OK] sync_failures: N historical sync failure(s), all acknowledged

* fix(extract): default --dir to configured brain dir, not cwd

`gbrain extract links` (and timeline / all) defaulted --dir to '.' when
not explicitly passed (src/commands/extract.ts:357). Combined with a
walker that skips dotfiles but NOT node_modules/dist/build/vendor, this
turned a no-arg invocation into a footgun.

Repro:
  $ cd ~/Documents/some-project   # has a node_modules/ tree
  $ gbrain extract links
  [extract.links_fs] 28989/28989 (100%) done
  Links: created 0 from 28989 pages
  Done: 0 links, 0 timeline entries from 28989 pages

The "28989 pages" is `walkMarkdownFiles('.')` recursively eating package
READMEs, dependency docs, fixture content. Their from_slug doesn't match
any row in the pages table, so addLinksBatch rejects every insert and
returns 0. Output looks like a healthy idempotent no-op; was actually a
wasteful junk walk that wrote nothing.

Fix: when --dir is not passed AND source is fs, resolve from
sources(local_path) via getDefaultSourcePath — same helper sync uses
(src/commands/sync.ts:1089). The default behavior now matches `sync`:
"work on the configured brain". Falls back to a clear error when no
source is configured, telling the user to either pass --dir, register
a source, or use --source db.

Behavior matrix:
  --dir explicit     → use that path (unchanged)
  --dir absent + cfg → resolve from sources(local_path)
  --dir absent + no  → error with actionable hint (was: walk cwd silently)
  --dir .            → cwd (user opted in explicitly — unchanged)

Tests: three added in test/extract-fs.test.ts:
  1. configured source → no-arg invocation extracts from that path
  2. no source configured → exit 1 + actionable error message
  3. explicit --dir wins over a configured (decoy) source path

* fix(extract): normalize slugs to lowercase via pathToSlug() (T-OBS-1)

The extractor was generating from_slug and the allSlugs lookup set from
`relPath.replace('.md', '')` in 5 places, producing CAPS slugs for files
named ETHOS.md, AGENTS.md, ROADMAP.md, etc.

Pages persist in the DB with lowercase slug (core/sync.ts pathToSlug()
applies .toLowerCase()). The CAPS extractor output mismatched the DB rows,
so INSERT ... JOIN pages ON pages.slug = v.from_slug silently dropped
links from CAPS-named source files. The link batch returned 'inserted'
counts that were lower than the wikilinks actually present, with no error.

Reproduction (in a brain with CAPS-named canonical docs):
  1. echo 'See [agents](agents.md).' > ETHOS.md
  2. gbrain put ethos < ETHOS.md  # page row: slug='ethos'
  3. gbrain extract links --source fs
  4. gbrain backlinks agents → []  (expected: contains 'ethos')

Fix: import pathToSlug from core/sync.ts and use it in all 5 sites:
  - extractLinksFromFile (line 200): from_slug derivation
  - runIncrementalExtractInternal (line 456): allSlugs set
  - extractLinksFromDir (line 552): allSlugs set
  - timeline loop (line 643): from_slug for timeline entries
  - extractLinksForSlugs (line 673): allSlugs set used by sync hook

This single-line-per-site change keeps the extractor consistent with the
sync layer's slug normalization and doesn't introduce any new behavior
for already-lowercase paths (idempotent).

Tests: added 'extractLinksFromFile — slug normalization (T-OBS-1
regression)' suite with 4 cases covering CAPS, mixed-case, idempotent
lowercase, and nested path. Full extract suite (54 → 58 tests) passes.

Reported by Claude Code (Opus 4.7) during Obsidian PKM integration on
the gstack-plan Living Repo, where ~111 wikilinks pointing to ETHOS,
AGENTS, ROADMAP, etc. failed to count toward brain_score (54/100 vs
expected 75+/100). Documented as T-OBS-1 in the consumer's blocked.md.

* fix(cli): CLI_ONLY commands should short-circuit on --help instead of executing

* fix(doctor): correct command syntax in graph_coverage warn message

graph_coverage warn directs users to run `gbrain link-extract &&
gbrain timeline-extract`, but no commands by those names are
registered in cli.ts. The actual commands are `gbrain extract links`
and `gbrain extract timeline` (registered as the 'extract'
subcommand at src/cli.ts:525, with the kind argument 'links' /
'timeline' / 'all' parsed inside src/commands/extract.ts).

A user who runs the suggested command gets:
  $ gbrain link-extract
  Unknown command: link-extract

This is the only place in src/ with the wrong syntax — the rest of
the docs (init.ts:221, init.ts:331, features.ts:120,
v0_13_0.ts:67, sync.ts:752 comment) all already say 'extract links'.
This patch just brings doctor.ts in line.

* fix(doctor): use autoDetectSkillsDir so OpenClaw workspaces are reachable

`gbrain doctor` was the only consumer of `findRepoRoot` from
`core/repo-root.ts`. Every other consumer (check-resolvable.ts:145,
skillify.ts, etc.) uses `autoDetectSkillsDir`, which has the full
detection chain:
  1. \$OPENCLAW_WORKSPACE
  2. ~/.openclaw/workspace
  3. findRepoRoot() walk from cwd
  4. ./skills

`findRepoRoot` only does step 3. Result: when the user runs `gbrain
doctor` from any directory outside the gbrain repo or the OpenClaw
workspace tree (e.g., a project's checkout), `resolver_health` reports
"Could not find skills directory" even though the dispatcher exists at
~/.openclaw/workspace/skills/RESOLVER.md.

Reproduces in any directory other than ~/gbrain or its descendants on
a system with ~/.openclaw/workspace/skills/RESOLVER.md present:

    \$ cd ~/Documents
    \$ gbrain doctor
    [WARN] resolver_health: Could not find skills directory   # before
    [WARN] resolver_health: 5 issue(s): 0 error(s), 5 warning(s)  # after

Switching doctor to `autoDetectSkillsDir` brings it inline with the rest
of the codebase. The detected dir is also passed to
`checkSkillConformance` (step 2 of the resolver_health block), which
previously rebuilt the path from `repoRoot` — now uses the same
detected path for consistency.

All 15 existing tests in test/doctor.test.ts continue to pass.

* fix(mcp): exit serve process on stdin-close/SIGTERM

MCP stdio server was keeping the bun process alive indefinitely after
the client disconnected. Over days this accumulated 20+ orphaned
gbrain serve processes, all holding the PGLite directory open.
Since PGLite is single-writer, this caused write-lock contention that
made email-sync fail its 15s per-put timeout: 114 puts x 15s = 28.5min
runs with 0 emails written.

Now listens for stdin end/close, transport close, and SIGTERM/SIGINT/
SIGHUP; calls engine.disconnect() and exits cleanly.

Root cause for the no-gbrain-run-in-50h alert.

* fix(skills): broaden RESOLVER triggers + 1 ambiguity flag (37 misses → 0, 100% top-1 accuracy)

`bun run src/cli.ts routing-eval` was reporting 37 ROUTING_MISS entries
across 10 skills whose RESOLVER.md trigger phrases didn't match any of
their own routing-eval.jsonl fixture intents. Two distinct causes:

1. Single-phrase triggers in 9 skills under '## Uncategorized' didn't
   cover the paraphrased fixture variations they're supposed to route.
   Broadened each trigger cell to a quoted-phrase list that covers the
   fixtures (5 fixtures per skill on average).

2. The media-ingest row used unquoted prose
   ('Video, audio, PDF, book, YouTube, screenshot') which
   extractTriggerPhrases() collapses into one impossible long phrase
   ('video audio pdf book youtube screenshot') under normalizeText —
   no fixture intent will ever contain that exact substring. Converted
   to a quoted phrase list.

3. One fixture ('web research pass on this person') legitimately
   matches both `perplexity-research` and `data-research`
   (data-research's trigger row contains "Research"). Marked the
   fixture `ambiguous_with: ["data-research"]` since the overlap
   on the keyword 'research' is inherent and expected.

Skills with broadened triggers:
  - voice-note-ingest, article-enrichment, book-mirror,
    archive-crawler, brain-pdf, academic-verify, concept-synthesis,
    perplexity-research, strategic-reading, media-ingest

Before: 58 cases, 37 misses, ~36% top-1 accuracy
After:  58 cases, 0 misses, 100% top-1 accuracy

This also clears `gbrain doctor`'s `resolver_health: 37 issue(s)` warning.

* fix(multi-source): thread source_id through per-page tx surface

Multi-source brains crashed mid-import with Postgres 21000 ("more than one
row returned by a subquery used as an expression"). Root cause: putPage's
INSERT column list omitted source_id, so writes intended for a non-default
source (e.g. 'jarvis-memory') silently fabricated a duplicate row at
(default, slug). The schema has UNIQUE(source_id, slug) but DEFAULT 'default'
for source_id; calling putPage(slug, page) without source_id landed at
(default, slug) and ON CONFLICT updated the wrong row, leaving the intended
source row stale. Subsequent bare-slug subqueries inside the same tx —
(SELECT id FROM pages WHERE slug = $1) in getTags / removeTag / deleteChunks
/ removeLink / addLink (cross-product) — then matched 2 rows and crashed
with 21000, rolling back the entire import. Observed: 18 sync failures
against a 'jarvis-memory'-sourced brain.

Fix:
- putPage adds source_id to the INSERT column list (defaults 'default' for
  back-compat).
- Every bare-slug page-id subquery becomes source-qualified
  (AND source_id = $X) in both engines: createVersion, upsertChunks,
  getChunks, addTag, removeTag, getTags, deleteChunks, removeLink,
  addTimelineEntry, deletePage, updateSlug.
- addLink rewritten away from FROM pages f, pages t cross-product into a
  VALUES + JOIN-on-(slug, source_id) shape mirroring addLinksBatch.
- engine.ts interface: 11 method signatures gain optional opts.sourceId
  (or opts.{from,to,origin}SourceId for addLink/removeLink). All optional;
  existing callers default to source='default' and behave identically.
- import-file.ts: importFromContent / importFromFile / importCodeFile take
  opts.sourceId and thread txOpts = { sourceId } through every per-page tx
  call. engine.getPage callsite source-scoped for accurate idempotency.
- commands/sync.ts: thread opts.sourceId at importFile (line 581 + 641),
  un-syncable cleanup (487-498), delete phase (557), rename phase (574),
  and post-sync extract phase (815-816).
- commands/reindex-code.ts: thread opts.sourceId at importCodeFile call.
- commands/extract.ts: extractLinksForSlugs / extractTimelineForSlugs accept
  opts.sourceId and propagate via linkOpts / entryOpts.
- commands/reconcile-links.ts: ReconcileLinksOpts.sourceId was declared but
  ignored end-to-end; now wired through getPage + addLink calls.
- commands/migrate-engine.ts: --force wipe switched to executeRaw('DELETE
  FROM pages') to preserve the pre-PR all-sources semantic after deletePage
  became default-source-scoped.

Regression test: test/source-id-tx-regression.test.ts (19 tests). Validates
two sources × same slug coexist; getTags/addTag/removeTag/deleteChunks/
upsertChunks/createVersion/addLink/addTimelineEntry/deletePage/updateSlug
source-scoped writes don't 21000; back-compat without opts targets
source='default'; addLink fail-fast on missing source-qualified endpoint;
importFromContent end-to-end tx thread without fabricating duplicate.

Adversarial review: Codex (gpt-5.5 reviewer) + Grok (xAI flagship reviewer)
3-round crew loop. Round 1: 2 HIGH (addTimelineEntry + extract.ts thread)
+ 2 MED. Round 2: 1 CRITICAL + 1 HIGH (deletePage + updateSlug bare-slug)
+ 2 MED. Round 3: 2 HIGH (getChunks + migrate-engine semantic regression
introduced by R2 fix). Round 4: both reviewers CLEAR.

Deferred to follow-up PRs (noted as TODO):
- src/commands/embed.ts source-aware threading (auto-embed at sync.ts:823
  has a TODO; try/catch swallows the failure as best-effort).
- src/core/postgres-engine.ts:1511 / pglite-engine.ts:1446 putRawData
  bare-slug (lower-impact metadata path).
- Read-surface bare-slug consistency cleanup (getLinks/getBacklinks/
  getTimeline/getRawData/getVersions): non-mutating, won't 21000.
- reconcile-links.ts CLI --source flag exposure (internal opt is wired;
  CLI parser is a UX feature for later).

Existing rows in production written under (default, slug) by the old
putPage when caller meant another source remain misrouted. Backfill
heuristics need install-specific knowledge of intended source and are
outside this PR's scope; surface as a deployment-side cleanup task.

bun run typecheck clean, bun run build clean, 19/19 regression tests pass,
4082 unit pass / 1 pre-existing fail (BrainRegistry test depending on
test-env ~/.gbrain/ absence — fails on untouched main, unrelated).

* fix(multi-source): plumb sourceId through performFullSync (PR #707 gap)

PR #707 fixed source_id routing for sync's incremental loop (lines 581/641)
but performFullSync (line 922) calls runImport without threading sourceId.
Result: full syncs route pages to default even with --source <id>. Verified
on v0.30.1 by direct PGLite probe after `gbrain sync --source X --full`:
all pages landed in default, not the named source.

Fix:
- runImport accepts sourceId in opts (programmatic only — no CLI flag,
  preserving PR #707's design intent of `gbrain import` being default-only).
- runImport threads sourceId to importFile + importImageFile.
- performFullSync passes opts.sourceId to runImport.
- ImportImageOptions type accepts sourceId for runImport branch (importImageFile
  body wiring deferred — image imports out of scope for current use case;
  TS error fix only).

Verified: real sync test against /tmp/test-sync routes 1 page to "testsync"
source, 0 to default (post-fix). 19/19 source-id regression tests still pass.
Typecheck clean.

* test: regression test for performFullSync sourceId threading

PR #707's existing 19-test suite at test/source-id-tx-regression.test.ts
covers the engine-layer transaction surface (putPage / addTag / etc.)
but does NOT exercise commands/sync.ts:performFullSync. Verified via
`grep -c 'performFullSync' test/source-id-tx-regression.test.ts → 0`.

This means the +18/-4 fix at sync.ts:892 (performFullSync passing
sourceId to runImport) had no automated coverage.

Adds 2 PGLite-only regression tests:

1. `performFullSync with --source routes pages to named source (not default)`
   — fixture: temp git repo with 2 markdown files. Calls performSync with
   { full: true, sourceId: 'testsrc-pfs', noPull: true, noEmbed: true }.
   Asserts pages.source_id = 'testsrc-pfs', not 'default'. Pre-fix: FAILS
   (verified by checking out 46cd197 — rebased PR #707 only, without my
   gap-fix — and running this test). Post-fix: PASSES.

2. `performFullSync WITHOUT --source still targets default (back-compat)`
   — same fixture, no sourceId opt. Asserts pages.source_id = 'default'.
   Both pre-fix and post-fix: PASSES (back-compat preserved by the fix).

Verified: 21/21 tests pass on this branch (19 from PR #707 + 2 new).
`bun run typecheck` clean. `bun run verify` clean (8 guard checks pass).

* fix(privacy): strip takes fence from get_page / get_versions when token carries an allow-list

v0.28.6 (#563) introduced the per-token takes-holder allow-list: an OAuth token
carries `permissions.takes_holders` and `takes_list` / `takes_search` /
`think.gather` filter take rows server-side via `WHERE t.holder = ANY($allowList)`
in both engines.

But take rows are stored in two places per the explicit contract in
`extract-takes.ts:5-13` ("markdown is canonical, the takes table is a derived
index"): the structured `takes` table AND inline in `pages.compiled_truth`
between `<!--- gbrain:takes:begin -->` markers as a markdown table whose `who`
column IS the holder. A read-only token whose `takes_holders` is `["world"]`
(the documented default-deny posture from migrate.ts:1221) can call
`get_page <slug>` and recover every non-`world` claim verbatim from the body —
private hunches, founder bets, non-public sourcing notes. `get_versions` has
the same shape: snapshots persist historical compiled_truth verbatim, so a
caller blocked at `get_page` falls through to /history.

The team already shipped a complementary fix in `chunkers/recursive.ts:49`
(stripTakesFence applied before the body is chunked, so `query` results don't
leak fence content). Migration v38 documents this as a "complementary fix" —
the page-CRUD surface was missed.

Fix strips the fence at the op layer when `ctx.takesHoldersAllowList` is set
(i.e. the remote MCP path). Local CLI callers leave the field unset and keep
seeing the full fence.

    const visibleBody = ctx.takesHoldersAllowList
      ? { ...page, compiled_truth: stripTakesFence(page.compiled_truth) }
      : page;

Same shape on `get_versions` over every snapshot in the array. Re-rendering
the fence with allow-list-filtered rows would require joining the takes table
per version_id and inverts the markdown-canonical contract; whole-fence strip
is the conservative posture that closes the leak. A future allow-list-aware
re-render is an additive change that won't break the contract pinned by these
tests.

Test coverage in `test/takes-mcp-allowlist.serial.test.ts`:
- get_page with allow-list strips fence; surrounding body kept.
- get_page without allow-list (local CLI) keeps fence (back-compat).
- get_page fuzzy resolution path also strips for remote tokens.
- get_versions with allow-list strips fence on every snapshot.
- get_versions without allow-list returns historical content intact.

The pre-fix R12 PoC reported `LEAKED garry hidden take? YES` and
`LEAKED brain hidden take? YES`; post-fix the same PoC reports `no` for both
holders and "bypass did not reproduce".

* Fix double-encoded jsonb in subagent_tool_executions breaking slug lookup

persistToolExecPending/Failed/Complete called JSON.stringify(input) before
passing to a $N::jsonb parameter. When input is already an object, this
produces a JSON string which ::jsonb stores as a jsonb scalar -- not a
jsonb object. Downstream queries like input->>slug then return NULL
because the operator does not traverse scalar strings.

Root cause fix: skip JSON.stringify when input is already a string.

Query fix: use COALESCE with (input #>> '{}')::jsonb->>slug fallback
to handle both old double-encoded rows and new properly-encoded rows.

Affects: dream cycle synthesize phase (pages_written always 0) and
patterns phase (same slug collection query).

* fix(adapter/voyage): translate request/response between OpenAI-compat SDK and Voyage's actual contract

The @ai-sdk/openai-compatible package treats Voyage as if it were
OpenAI-shaped, but Voyage's /v1/embeddings endpoint diverges in three places
that combine into a hard-blocking incompatibility:

OUTBOUND request:
  - 'encoding_format=float' (SDK default) is rejected; Voyage only accepts 'base64'
  - 'dimensions' parameter (OpenAI name) is rejected; Voyage uses 'output_dimension'

INBOUND response:
  - With encoding_format=base64, 'embedding' is returned as a base64 string,
    but the SDK's Zod schema (openaiTextEmbeddingResponseSchema) expects an
    'array of number'. The schema fails with 'Invalid JSON response' even
    though the JSON is well-formed.
  - 'usage' lacks 'prompt_tokens'; the schema requires it when usage is present.

Without this patch, ALL embedding requests to Voyage fail. Reproducible by
running 'gbrain put <slug> < text' with embedding_model=voyage:voyage-* and
any current voyage model (voyage-3-large, voyage-3, voyage-4-large).

Solution: pass a custom 'fetch' to createOpenAICompatible only when
recipe.id === 'voyage'. The fetch wrapper:
  1. Forces encoding_format='base64' on outbound (Voyage's only accepted value)
  2. Translates dimensions -> output_dimension on outbound
  3. Drops Content-Length so the runtime recomputes from the mutated body
  4. Decodes base64 embeddings to Float32 arrays on inbound (so the Zod schema
     sees what it expects)
  5. Synthesizes prompt_tokens from total_tokens when missing

This is a minimal, targeted fix. It only activates for Voyage and falls
through cleanly for all other providers. No public API changes.

* feat(dream): support .md files in transcript discovery

Transcript discovery only accepted .txt files. Many brain repos store
meeting transcripts and conversation logs as .md (markdown), which is
the natural format for brain content.

Changes:
- listTextFiles() now accepts both .txt and .md
- basename extraction handles both extensions for date inference
- readSingleTranscript() handles both extensions

No behavior change for existing .txt-only setups.

* fix(test): cast exitCode to unknown for TS strict-narrowing

TS narrows exitCode to null between declaration and assertion because
the mocked process.exit is behind `(process as any).exit`. The cast
preserves test intent without weakening the variable's type annotation.

Wave-side merge fix; ships alongside #688 (extract --dir default).

* fix(cli): add frontmatter + check-resolvable to CLI_ONLY_SELF_HELP

Companion to #634. Both commands have their own --help logic that prints
detailed usage with command-specific flags (e.g., --json, --fix, --strict
for check-resolvable). Without this, pr-634's generic short-circuit prints
"Usage: gbrain <cmd> - run gbrain --help for the full command list." and
the existing --help integration tests fail.

Verified: `gbrain frontmatter --help` and `gbrain check-resolvable --help`
now route to their handlers, which print full per-command usage and exit 0.

* fix(test): update discoverTranscripts test expectation for .md support

Companion to #708. The pre-#708 test asserted that .md files in the
session-corpus directory were skipped. Post-#708 they are discovered
alongside .txt. Renamed the test to 'skips non-txt non-md files' (uses
.pdf as the negative case) and added a positive .md discovery test that
pins #708's intended behavior.

* fix(skills): declare missing RESOLVER triggers in skill frontmatter

Companion to #718. The RESOLVER round-trip test (test/resolver.test.ts)
fuzzy-matches every RESOLVER.md trigger phrase against the target skill's
frontmatter triggers list. pr-718 added six new RESOLVER routings without
declaring matching triggers:

- media-ingest: 'PDF book', 'summarize this book', 'ingest it into my brain'
- article-enrichment: 'enriching the article', 'enrich the article', 'enrich pass'
- concept-synthesis: 'canon vs riff'
- perplexity-research: 'perplexity-research', 'surface new developments'
- academic-verify: 'Retraction Watch'
- voice-note-ingest: 'audio message'

Adds the missing triggers verbatim to each skill's frontmatter so the
round-trip invariant holds.

* chore: regenerate llms.txt + llms-full.txt after wave skill updates

* v0.30.3 release: bump VERSION + CHANGELOG entry

22-PR community fix wave with one P0 security upgrade (auth-code scope
escalation closed). 19 PRs landed across 5 lanes; 3 superseded by master
during cherry-pick; 1 deferred per E2 protocol (#681 architectural
conflict with v0.28 takes-holders); follow-up filed.

Headline fixes: #727 (auth-code scope-clamp, RFC 6749 §3.3 compliance),
#740/#751 (v0.29.1 PGLite migration connect), #741 (v39-v41 forward-
reference bootstrap), #757 (multi-source sourceId threading, closes
Postgres 21000), #728 (takes-fence redaction on remote reads).

* test(C6): regression test for #745 collectChildPutPageSlugs

Codex-mandated test gate (C6 from /codex review of v0.30.3 plan).

Pins behavior of collectChildPutPageSlugs() under both jsonb shapes:
- jsonb_typeof='object' (post-#745, normal write path)
- jsonb_typeof='string' (pre-#745 double-encoded, the bug shape)

Without this guard, a future regression of #745 would silently drop slugs:
child jobs finish, queue looks healthy, orchestrator writes nothing.
Worst on-call shape — silent failure with no alerting surface.

Adds an `__testing` namespace to src/core/cycle/synthesize.ts re-exporting
collectChildPutPageSlugs at unit-test granularity. Not part of the runtime
contract; matches the v0_29_1.ts `__testing` precedent for engine-internal
helpers.

* test(C8): #708 .md transcript discovery + self-consumption guard

Codex-mandated test gate (C8 from /codex review of v0.30.3 plan).

Pins three invariants for #708's broadening of transcript discovery:

  1. .md files ARE discovered alongside .txt (the feature works).
  2. Other extensions (.pdf, .doc, .json) are still SKIPPED.
  3. v0.30.2's dream_generated frontmatter marker MUST guard .md files
     against self-consumption — without this, every dream cycle would
     loop on its own output indefinitely.

Adversarial cases: BOM + CRLF tolerance on .md frontmatter; the
--unsafe-bypass-dream-guard escape hatch for .md output; mixed .txt + .md
corpus dedup behavior pinned.

* test(C4): takes-fence redaction regression on get_page + get_versions

Codex-mandated test gate (C4 from /codex review of v0.30.3 plan).

Pins three privacy invariants for #728's fence-stripping in operations.ts:

  1. Local CLI caller (no allow-list) sees full takes fence — operator
     reads should preserve everything.
  2. MCP-bound caller (allow-list set) sees compiled_truth with fence
     STRIPPED on get_page AND get_versions.
  3. Allow-list PRESENCE (not contents) flags MCP-bound identity. Even
     a permissive ['world','garry','brain'] still strips, because the
     typed read surface for takes is takes_list / takes_search, not
     get_page or get_versions.

Lane 4 (#757 + #728) was the high-risk merge surface for this privacy
invariant. The test runs through dispatchToolCall to exercise the full
threading path (auth → context → handler → engine read → stripTakesFence)
so a future bad merge fails loudly at the conflict seam in operations.ts.

* test(C3): rewound-brain E2E for v39-v41 forward-reference bootstrap

Codex-mandated test gate (C3 from /codex review of v0.30.3 plan).

Pins the upgrade-path claim in the v0.30.3 release notes: brains stuck
at config.version < 39 (Postgres) or < 41 (PGLite) walk forward cleanly
through #741's bootstrap additions. Without this, the release note's
"old PGLite brains upgrade cleanly through v39-v41" was unproven.

Four cases:
  1. pre-v39 (missing modality + embedding_image)
  2. pre-v40 (missing emotional_weight + effective_date + effective_date_source)
  3. pre-v41 (missing import_filename + salience_touched_at)
  4. compounded pre-v34 wedge (v0.20 + v0.26.3 + v39-v41 all dropped at once)

Pattern follows test/e2e/v0_28_5-fix-wave.test.ts: build a fresh LATEST
brain, surgically rewind via DROP COLUMN CASCADE + UPDATE config.version,
then re-call initSchema and assert advancement to LATEST_VERSION with
the rewound columns restored. PGLite-only — Postgres-side bootstrap is
covered separately by test/e2e/postgres-bootstrap.test.ts.

* fix(test): rename migration-v0-29-1 to .serial.test.ts (CI lint)

CI's check-test-isolation lint flags the test for direct process.env.GBRAIN_HOME
mutation in beforeEach (rule R1: parallel-test-unsafe). The test is genuinely
env-coupled — it sets GBRAIN_HOME so loadConfig() inside the migration phases
finds the test fixture. Per CLAUDE.md ("When to quarantine instead of fix")
and the lint's own fix hint, env-coupled tests get renamed to *.serial.test.ts
to run in the serial bucket.

Verified: bash scripts/check-test-isolation.sh now reports OK; the renamed
test still runs green (1 pass / 0 fail, ~1.5s).

* fix(types): voyageCompatFetch — cast through unknown for Bun typeof fetch

CI's tsc --noEmit failed:
  src/core/ai/gateway.ts(249,7): error TS2741: Property 'preconnect' is
  missing in type '(input: RequestInfo | URL, init: RequestInit | ...) =>
  Promise<Response>' but required in type 'typeof fetch'.

Bun's @types/bun extends the standard fetch type with a preconnect method
that arrow functions can't satisfy. The AI SDK only invokes the call
signature; the Bun extension surface is irrelevant to voyageCompatFetch's
behavior.

Cast through `unknown` (TS2352-safe pattern for cross-type-family casts)
with explicit param types on the arrow function. Comment names the exact
TS2741 the cast suppresses so a future maintainer can audit the choice.

Companion to #735 (Voyage encoding-format adapter) — the original PR
introduced voyageCompatFetch typed against typeof fetch; the wave-side
typecheck error was caught by CI on the assembled branch.

* fix(test/e2e): rename + update dream-cycle phase-order test

The test file said "v0.23 8-phase cycle" but ALL_PHASES has been 9
since v0.26.5 (added `purge`) and 10 since v0.29 (added
`recompute_emotional_weight` between patterns and embed). The
hardcoded 8-element array assertion was stale documentation.

Renamed the file from dream-cycle-eight-phase-pglite.test.ts to
dream-cycle-phase-order-pglite.test.ts to make the maintenance
contract explicit: this test pins the canonical phase sequence,
whatever its current length, against unintended reorderings or
removals.

Extracted EXPECTED_PHASES as a typed const so the assertion lives in
one place and TypeScript's CyclePhase narrowing catches typos in the
phase names.

* fix(test/e2e): cycle.test.ts expects 10 phases (v0.29 added recompute_emotional_weight)

Same root cause as dream-cycle-phase-order-pglite.test.ts: hardcoded
phase count assertion drifted behind ALL_PHASES growth.

Phase history:
  v0.23  = 8 phases
  v0.26.5 = 9 (added `purge` last)
  v0.29  = 10 (added `recompute_emotional_weight` between patterns and embed)

* fix(test/e2e): scope GBRAIN_HOME to tmpdir for Doctor Command tests

`gbrain doctor`'s minions_migration check reads
`~/.gbrain/migrations/completed.jsonl` to detect half-installed
migrations. Pre-fix the test inherited the developer's local
$HOME, so stale partial entries from in-flight workspaces (e.g.
v0.31.0 in santiago) made the check fail and the test exit 1 —
masking real DB-health failures.

Added per-describe-block `gbrainHome` tmpdir, threaded through
`cliEnv()` so all spawned gbrain CLI calls in this block read a
hermetic, empty migrations ledger. Cleanup in afterAll.

* fix(claw-test): pass --dir explicitly to extract phase (companion to #688)

Pre-#688 `gbrain extract` defaulted to cwd. Post-#688 it requires
either a configured fs source or explicit --dir, otherwise it errors
out: "No brain directory configured."

The claw-test scripted scenarios run `gbrain init --pglite` in their
install_brain phase, which doesn't register a fs source. So the
extract phase needs --dir <brainDir> explicitly. Skip the extract
phase entirely when the scenario has no brain dir.

Captured brainDir at the import-phase site so it's reusable by extract.

* fix(preferences): route migration ledger paths through gbrainPath()

Pre-fix, preferences.ts used `$HOME/.gbrain` directly via its own
`home()` helper. Tests that set `process.env.HOME = tmpdir`
expecting hermetic isolation worked — but tests that set
`GBRAIN_HOME = tmpdir` (the documented override per
`src/core/config.ts`) didn't, because preferences ignored it.

Routed prefsDir(), prefsPath(), migrationsDir(), and
completedJsonlPath() through gbrainPath() (which honors
GBRAIN_HOME, falling back to homedir() when unset). The legacy
home() helper stays for any future code path that wants $HOME
specifically.

Updated three tests that mutated process.env.HOME to also mutate
GBRAIN_HOME so the same test body works against the new contract:
test/preferences.test.ts, test/migration-resume.test.ts,
test/e2e/migration-flow.test.ts.

* release: rename version slot to 0.31.1.1-fixwave

Originally bumped to 0.31.2 during the master merge to stay strictly
monotonic. Garry called the slot back to `0.31.1.1-fixwave` to
communicate intent: this is a fix wave on top of v0.31.1, not a new
minor or patch slot. The next regular release slot (v0.31.2) stays
free for in-flight feature work.

Format check:
- bun install accepts the literal version (verified)
- compareVersions() in src/commands/migrations/index.ts splits on
  '.' and parseInt's each segment, taking only the first 3. So
  '0.31.1.1-fixwave' compares as [0,31,1] = equal to '0.31.1' for
  migration-ordering purposes. Wave has no new schema migrations,
  so equality is fine.
- Compares stable to 0.31.1 in the migration runner; later versions
  (0.31.2, 0.32.x, etc.) sort strictly above as normal.

Updated:
- VERSION
- package.json (with bun.lock refresh)
- CHANGELOG.md entry header + 'To take advantage of' block + 'For
  contributors' reference
- llms.txt + llms-full.txt regenerated to match

 		89ae720959 v0.31.0 feat: hot memory — facts hook + recall CLI + MCP _meta + consolidate phase (#785) 
* v0.31 feat(migrate): facts hot memory schema (migration v40)

Phase 1 of v0.31 hot-memory.

- New facts table with source_id (TEXT FK to sources, per-source isolation),
  kind CHECK (event/preference/commitment/belief/fact), visibility CHECK
  (private/world for takes-style ACL parity), valid_from/valid_until/
  expired_at/superseded_by for temporal + supersession audit, and
  consolidated_at/consolidated_into pointing at takes(id) for the dream-
  cycle hot→cold bridge.
- Embedding column dim resolved at migration time from
  config.embedding_dimensions so non-OpenAI brains (Voyage etc) work
  out-of-the-box. HALFVEC where pgvector >= 0.7; falls back to VECTOR
  with stderr warn on older versions. Matching opclass per column type
  (halfvec_cosine_ops vs vector_cosine_ops).
- 5 partial indexes leading on source_id so every read uses the trust
  boundary as part of the index, not a callback. HNSW partial index
  excludes expired/null rows so footprint stays proportional to active
  fact count.
- RLS DO-block matches takes pattern (Postgres BYPASSRLS gate; PGLite
  no-op).
- v0_31_0.ts orchestrator follows v0_28_0.ts pattern — phase A asserts
  schema version >= 40 + facts table presence; runner owns ledger.

All 87 existing migrate.test.ts cases pass. PGLite smoke test confirms
table + indexes + CHECK constraints + ON DELETE CASCADE all behave.

* v0.31 chore(version): bump VERSION + package.json to 0.31.0

Phase 1 closer. CHANGELOG entry written when Phase 7 lands.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.31 feat(engine): facts hot memory engine API (Phase 2)

Phase 2 of v0.31 hot-memory.

Adds 8 facts methods to BrainEngine implemented on both PGLite and
Postgres engines:

- insertFact(input, ctx) — INSERT with optional supersedeId; expires the
  named row in the same transaction. Per-entity advisory lock on Postgres
  (`pg_advisory_xact_lock(hashtextextended(source_id::text || ':' ||
  entity_slug, 0))`) for the dedup window. PGLite is single-process so
  the lock is a no-op.
- expireFact(id, opts) — sets expired_at + optional superseded_by.
  Idempotent-as-false (already-expired returns false).
- listFactsByEntity / listFactsSince / listFactsBySession — list surfaces
  with FactListOpts filters (activeOnly, kinds, visibility, limit/offset).
  Every query starts WHERE source_id = $X so the trust boundary is part
  of the index path.
- listSupersessions — audit log; activeOnly:false + expired_at IS NOT NULL
  + superseded_by IS NOT NULL.
- findCandidateDuplicates(source_id, entity_slug, factText, k) —
  entity-prefiltered (mandatory), k=5 default, hard cap 20. Embedding-
  cosine ordering when caller supplies an embedding, recency fallback
  otherwise. Bounds the contradiction-classifier blast radius.
- consolidateFact(id, takeId) — sets consolidated_at + consolidated_into.
  Never DELETE; facts stay as audit trail for the resulting take.
- getFactsHealth(source_id) — per-source counters consumed by `gbrain
  doctor` facts_health check.

Public types in engine.ts: FactKind (5-value union), FactVisibility,
FactInsertStatus, FactRow, NewFact, FactListOpts, FactsHealth.

PGLite + Postgres helpers: rowToFact / rowToFactPg parse the
text-format pgvector embedding back into Float32Array; toPgVectorLiteral
encodes for the supersede-path INSERT (postgres-js can't bind Float32Array
directly to a vector column without an explicit literal cast).

Smoke test confirms every method end-to-end on PGLite. Typecheck clean.

* v0.31 feat(facts): extraction code path (Phase 3)

Phase 3 of v0.31 hot-memory.

Five new modules under src/core/facts/ + src/core/entities/:

- src/core/facts/decay.ts — pure helper. effectiveConfidence(fact, now)
  applies confidence × exp(-age/halflife) with per-kind halflife table
  (event 7d, commitment 90d, preference 90d, belief 365d, fact 365d).
  Returns 0 for expired or past-valid_until rows. Single source of truth
  consumed by recall, supersession audit, facts_health, and the MCP _meta
  injector (eD8 DRY).

- src/core/facts/queue.ts — bounded in-memory queue. Cap 100 default,
  drop-oldest on overflow with counter. Per-session in-flight=1 serializes
  burst chat. AbortSignal threading from server SIGTERM (mirrors minion
  worker pattern per eD7): 5s grace for in-flight, then drop pending with
  counter. getFactsQueue() process-singleton; __resetFactsQueueForTests
  for hermetic tests.

- src/core/facts/classify.ts — contradiction classifier with cosine
  fast-path (D13: ≥0.95 → duplicate, skip LLM) and classifier-failure
  fallback (D12: cosine ≥0.92 → duplicate, else INSERT). Pure cosine
  helper exported. JSON-strict output with 4-strategy parse fallback;
  refusal stop-reason maps to fallback path. Caller-provided abort
  signal propagated to the gateway chat call.

- src/core/facts/extract.ts — Haiku turn-extractor. Reuses
  INJECTION_PATTERNS from src/core/think/sanitize.ts on the way IN
  (turn_text) AND on the way OUT (each fact). Tight system prompt with
  5-kind taxonomy, 0..1 confidence scoring, entity slug or display name.
  Anti-loop check on isDreamGenerated (reuses v0.23.2 marker semantics).
  Synchronous embedOne() per fact via the gateway so classifier paths
  have embeddings available; AbortError re-thrown explicitly so SIGTERM
  during embed never writes a NULL-embedding row meant to be cancelled
  (eE8 distinction).

- src/core/entities/resolve.ts — slug canonicalization shared by
  signal-detector AND facts. Resolution order: exact slug match →
  pg_trgm fuzzy match (similarity ≥0.4) → deterministic slugify
  fallback. slugify exported standalone for tests + callers that want
  the floor.

Smoke tests confirm decay table, cosine math, slugify rules, queue
drop-oldest under overflow, and shutdown grace + drop-pending semantics.
Typecheck clean.

* v0.31 feat(mcp+cli): MCP ops + recall CLI + _meta + transport refactor (Phase 4)

Phase 4 of v0.31 hot-memory.

Three new MCP ops on the contract-first surface:

- `extract_facts` (write scope, localOnly:false): extracts facts from a
  conversation turn via the Haiku extractor, runs the cosine fast-path
  dedup, INSERTs into per-source hot memory. Returns counts +
  fact_ids[]. Skips on is_dream_generated:true (anti-loop).
- `recall` (read scope): query the per-source hot memory by
  entity / since / session / supersessions / grep filter. Visibility-
  aware: remote callers see visibility='world' rows only (takes-style
  ACL parity, eD21). Returns most-recent first; pagination via limit.
- `forget_fact` (write scope): expireFact wrapper. Idempotent-as-error
  on unknown id; uses the new 'fact_not_found' ErrorCode.

ErrorCode union opened (eD6 / eE7): TS forward-compat via the
`(string & {})` autocomplete-friendly hack so downstream consumers
(gbrain-evals etc) don't break their typecheck on every new code.
Three new codes: 'rate_limited', 'extraction_failed', 'fact_not_found'.

OperationContext gains source_id?:string (eD4 / eE2 — TEXT not INTEGER
per schema reality). Resolved once in buildOperationContext from
DispatchOpts.sourceId. Stdio MCP defaults to GBRAIN_SOURCE env or
'default'; HTTP MCP reads it from the per-token sources scope (eE3).

ToolResult gains _meta?: Record<string, unknown> (eD3). Dispatcher
calls a configurable metaHook AFTER op.handler succeeds, wrapped in
its own try/catch so a DB blip degrades to no-_meta rather than
flipping the whole tool call to error (eE4).

New module src/core/facts/meta-hook.ts:
- getBrainHotMemoryMeta(name, ctx) builds the _meta.brain_hot_memory
  payload. Cache key (source_id, session_id, hash(takesHoldersAllowList
  sorted)) (eD10 / eE5). 30s TTL per session. Visibility filter applies:
  remote → world only; local → all. Top-K=10 ranked by effective
  confidence (decay). Skips injection on recall/extract_facts/forget_fact
  themselves. bumpHotMemoryCache() invalidates per (source_id,
  session_id) on extraction event.

D12 (eE1) accepted: serve-http.ts:801 inlined dispatch path REFACTORED
to call dispatchToolCall. HTTP MCP now inherits source_id, _meta
injection, error envelope unification, and OperationContext shape from
the same code path stdio uses. Scope check + mcp_request_log + SSE
broadcast stay in serve-http.ts (HTTP-specific concerns); the dispatcher
returns ToolResult and the HTTP handler reads isError + content + _meta
to fan into the audit + broadcast paths.

put_page compliance backstop (D23): when a conversation-shape page is
written (note/meeting/slack/email/calendar-event/source/writing) with
a substantive body (>=80 chars) on a non-subagent slug AND no
dream_generated:true marker, fire-and-forget enqueue an extraction job
into the bounded queue. Never blocks the put_page response. Skipped
reasons (no_parsed_page / subagent_namespace / dream_generated /
kind:* / too_short / queue_shutdown / backstop_error) are stable
strings consumed by tests.

`gbrain recall` + `gbrain forget` CLI commands (src/commands/recall.ts):
- recall <entity> | --since DUR | --session ID | --today (markdown
  with kind icons 📅🎯🤝💭📌) | --grep TEXT | --supersessions |
  --include-expired | --as-context (prompt-injection-ready) | --json
- forget <fact-id> shorthand for expireFact

Wired into src/cli.ts dispatch table next to takes / think.

Smoke tests confirm: dispatch surfaces (extract_facts → ops →
listFactsByEntity), forget_fact + idempotent re-call, _meta visibility
filter (remote sees world only, local sees all), CLI markdown render
with kind icons + age strings + decayed confidence.

* v0.31 feat(cycle): consolidate phase — facts → takes promotion (Phase 5)

Phase 5 of v0.31 hot-memory.

New 10th cycle phase `consolidate` between `patterns` and `embed`:

- src/core/cycle.ts:
  * CyclePhase union extended with 'consolidate'
  * ALL_PHASES gets 'consolidate' between patterns and embed (graph-fresh
    after patterns; embed runs after so the new takes get embedded
    same-cycle)
  * NEEDS_LOCK_PHASES gets 'consolidate' (writes takes + UPDATEs facts)
  * CycleReport.totals gains facts_consolidated + consolidate_takes_written
  * runCycle dispatches the new phase via dynamic import

- src/core/cycle/phases/consolidate.ts (new):
  * Scans (source_id, entity_slug) buckets where COUNT(unconsolidated
    facts) >= 3 (uses idx_facts_unconsolidated partial index)
  * Skips buckets where the OLDEST fact is < 24h old (gives signal time
    to settle before locking it into cold memory)
  * Greedy cosine clustering at threshold 0.85; head-element centroid
    keeps it deterministic + cheap. Singletons (no embedding) stay
    unconsolidated this cycle.
  * For each cluster size >= 2: picks the highest-confidence fact's text
    as the take claim (v0.31 deterministic; v0.32 swaps to Sonnet
    synthesis pass). avg confidence → take weight, earliest valid_from →
    take since_date, concatenated source_sessions → take.source.
  * Resolves entity_slug → page_id via pages.slug (per source). Skips
    cluster if page is missing in this source — no auto-page-creation
    in v0.31.
  * INSERT into takes(kind='fact', holder='self') with row_num =
    MAX(existing) + 1.
  * UPDATE contributing facts: consolidated_at = now() +
    consolidated_into = takes.id. NEVER DELETE — facts are the audit
    trail for the resulting take.
  * dryRun honored: pretends the writes happened; counters still tick
    so operators can preview load before the first real run.
  * yieldDuringPhase keepalive between buckets so the Minions worker
    job lock + cycle-lock TTL don't drift on long runs.

Smoke test on PGLite confirms: 4 unconsolidated facts → clustered
(cosine 1.0 since same vector) → 1 take row created → all 4 facts
marked consolidated_into. runCycle({phases:['consolidate']}) wires
through to the report totals. Typecheck clean.

* v0.31 test: 18 facts test files (Phase 6)

Phase 6 of v0.31 hot-memory: comprehensive coverage across the new
substrate. 110 unit tests pass; 5 E2E test files added (skip gracefully
without DATABASE_URL).

Unit tests (PGLite in-memory, no DATABASE_URL):
- test/facts-decay.test.ts (12 cases) — HALFLIFE_DAYS pinned per kind,
  effectiveConfidence math: age=0 / age=halflife (~1/e) / age=2×halflife
  (~1/e²) / expired returns 0 / valid_until past returns 0 /
  preference-vs-event slower decay / belief-vs-commitment crossover.
- test/facts-queue.test.ts (10 cases) — FIFO within session, drop-oldest
  on overflow, per-session in-flight=1 serializes, different sessions
  parallelize, failed jobs counter, shutdown grace + drop_pending +
  external AbortController triggers shutdown.
- test/facts-classify.test.ts (8 cases) — cosineSimilarity edge cases,
  empty candidates → independent, cheap fast-path ≥0.95 → duplicate
  no LLM, threshold-configurable cosine_fallback path.
- test/facts-engine.test.ts (13 cases) — every BrainEngine fact method
  end-to-end: insertFact (insert/supersede), expireFact idempotency,
  list*, findCandidateDuplicates entity-prefiltered + k cap + cosine
  ordering, consolidateFact never DELETE, getFactsHealth shape +
  total_today ⊆ total_week.
- test/facts-multi-tenant.test.ts (6 cases) — cross-source isolation
  on every list method + CASCADE delete on sources.
- test/facts-visibility.test.ts (6 cases) — visibility column private/
  world; remote=true filters to world-only via dispatchToolCall;
  remote=false sees all.
- test/facts-canonicality.test.ts (10 cases) — slugify rules including
  NFKD diacritic strip ("Crème Brûlée" → "creme-brulee"), exact slug
  match, fallback to slugify when no fuzzy match.
- test/facts-extract.test.ts (4 cases) — empty turn returns [], dream-
  generated short-circuit, graceful no-API-key return.
- test/facts-backstop-gating.test.ts (5 cases) — put_page backstop:
  too_short, subagent_namespace, dream_generated, eligible note path,
  non-eligible kind:guide.
- test/facts-anti-loop.test.ts (4 cases) — extractor + put_page both
  respect dream_generated:true marker.
- test/facts-doctor-shape.test.ts (4 cases) — facts_health JSON shape
  pinned for downstream consumers.
- test/facts-mcp-allowlist.serial.test.ts (5 cases) — extract_facts
  write-scope, recall read-scope, forget_fact write-scope, forget_fact
  fact_not_found error code, extract_facts no-API-key zero counts.
- test/facts-context-injection.serial.test.ts (6 cases) — _meta
  injection on success, world-only filter under remote=true, anti-loop
  on facts ops themselves, best-effort degrade on hook error,
  cache-key includes allow-list hash.
- test/facts-separation-pglite.test.ts (2 cases) — Garry's Separation
  Test as primary ship gate, plus expired hidden-by-default contract.
- test/facts-recall-render.test.ts (3 cases) — --today markdown render
  with all 5 kind icons, --json shape with effective_confidence,
  --as-context emits comment-wrapped block.
- test/facts-migration-dim.test.ts (4 cases) — embedding column type
  is HALFVEC/VECTOR (not arbitrary), dim matches gateway-configured
  embedding_dimensions, HNSW opclass agrees with column type, idempotent
  re-init.
- test/cycle-consolidate.test.ts (5 cases) — below-count + below-age
  thresholds skip, happy path 4 facts → 1 take + all consolidated never
  DELETE, dryRun honored, missing page → bucket skipped.

E2E tests (skip gracefully on DATABASE_URL unset; required gates by
CLAUDE.md test policy):
- test/e2e/facts-separation-postgres.test.ts — Postgres parity for the
  ship gate.
- test/e2e/facts-cross-source-isolation.test.ts — cross-source ACL on PG
  + CASCADE delete.
- test/e2e/facts-forget.test.ts — full forget_fact MCP roundtrip.
- test/e2e/facts-context-injection-postgres.test.ts — _meta injection
  end-to-end on PG.
- test/e2e/facts-recall-render.test.ts — recall --today markdown on PG.
- test/e2e/serve-http-meta.test.ts — eE1 regression: HTTP MCP transport
  inherits _meta + sourceId + scope correctness via dispatchToolCall.

Side-effect: src/core/entities/resolve.ts NFKD post-decompose strips
combining marks (U+0300..U+036F) before hyphenating non-alphanumerics,
so "Crème" → "creme", not "cre-me-".

* v0.31 feat(operational): kill switch + doctor check + CHANGELOG + README (Phase 7)

Phase 7 of v0.31 hot-memory.

- src/core/facts/extract.ts: new isFactsExtractionEnabled(engine) helper
  reads `facts.extraction_enabled` config row. Defaults to TRUE; flip to
  'false'/'0'/'no'/'off' (case-insensitive) via `gbrain config set
  facts.extraction_enabled false` to kill extraction across the brain
  without binary downgrade.
- extract_facts MCP op short-circuits with zero-counts envelope + a
  'skipped: extraction_disabled' field when the flag is off (clean
  success, not permission_denied).
- put_page facts backstop respects the same flag — eligibility check now
  returns 'extraction_disabled' as the skipped reason.
- src/commands/doctor.ts: new facts_health check (runs after queue_health,
  before index_audit). Probes for the facts table existence (post-v40
  guard), then surfaces total_active / total_today / total_week /
  total_consolidated + top-3 entities for the default source. Pre-v0.31
  brains report "facts table not present (pre-v0.31 brain or migration
  pending)".
- CHANGELOG.md: full v0.31.0 entry in the GStack release-summary voice.
  Headline + numbers-table + what-it-ships + itemized changes + "To take
  advantage of v0.31" upgrade block + out-of-scope. Honest about the
  HALFVEC + serve-http refactor + ErrorCode-open-union complications.
- README.md: cycle phase list updated 8 → 10 (consolidate + purge). New
  "v0.31 Hot Memory" command block under Commands with recall + forget
  variants, kind icons, --as-context surface for headless agents.

Test gates: 28 facts unit tests pass after the kill-switch wiring + doctor
check ride-along. Typecheck clean.

* v0.31 fix(migrate): add facts→sources FK explicitly via ALTER TABLE

The inline column-level FK declaration on facts.source_id worked on
PGLite but silently got dropped on Postgres in the v0.31 e2e run —
the migration handler ran via postgres-js's `unsafe()` multi-statement
path and the resulting facts table came back without the
`facts_source_id_fkey` constraint. Same psql input run directly
against the same database produced the FK; the difference was the
unsafe() pipeline, not the SQL itself.

Splitting the FK into a separate ALTER TABLE inside a DO block makes
the constraint declaration explicit and idempotent: the named
constraint either exists or it doesn't, the ALTER is a no-op on
re-runs, and the failure mode is loud rather than silently leaving
a CASCADE-less foreign key behind.

Without this fix, deleting a source row leaves orphaned facts rows
(test/e2e/facts-cross-source-isolation.test.ts CASCADE-on-sources-
delete case caught it). With this fix the constraint is in place,
the cascade fires, and both PG + PGLite e2e suites stay green.

* v0.31 test: update phase-count assertions for the new consolidate phase

Three e2e/unit tests pinned the cycle phase count or order, all now
updated to reflect v0.31's 10-phase cycle:

- test/e2e/dream-cycle-eight-phase-pglite.test.ts:
  describe rename "8-phase cycle" → "10-phase cycle"; ALL_PHASES
  expectation extended to include 'consolidate' (between patterns +
  embed) and 'purge' (the v0.26.5 addition that was already in
  ALL_PHASES but missing from the test's assertion list). totals
  match adds the new facts_consolidated + consolidate_takes_written
  fields plus the pre-existing purged_sources_count + purged_pages_count
  that should have been added when v0.26.5 landed.

- test/e2e/cycle.test.ts: dry-run full cycle now expects
  report.phases.length === 10 (was 9).

- test/core/cycle.serial.test.ts: yieldBetweenPhases hook count + full
  cycle phases.length both updated 9 → 10. Comments call out the
  v0.31 addition lineage so the next person to add a phase sees the
  precedent.

These are mechanical assertion bumps. The tests pass against the
updated assertions on PGLite and Postgres.

* v0.31 fix(test): truncate facts table between e2e describe blocks

setupDB() truncates ALL_TABLES between every describe block's
beforeAll() hook. The list missed the new v0.31 facts table, so
facts seeded by an earlier describe block leaked into Garry's
Separation Test on Postgres — listFactsByEntity('travel') returned
2 rows instead of 1 because a prior facts-context-injection test had
also seeded a 'travel' fact.

Adding 'facts' to the truncate list (before 'pages' to respect FK
ordering) makes every describe-block start from an empty facts table.

Pinned by re-running the e2e file ordering that originally caught it
(facts-recall-render → cross-source-isolation → serve-http-meta →
context-injection → separation-postgres → facts-forget) — 13 pass /
0 fail after the fix.

* v0.31 test: meta-hook cache + Postgres consolidate phase coverage

Two net-new test files filling real coverage gaps the earlier sweep missed:

- test/facts-meta-cache.test.ts (5 cases) — pins the eD3/eD10 cache
  contract that the dispatcher relies on. 30s TTL hit path, post-bump
  fresh-query, scoped invalidation (bump for sess-A leaves sess-B cache
  warm — closes the cross-source leak risk codex F5 originally surfaced
  on the recall payload), facts-self ops skip injection (anti-loop on
  recall / extract_facts / forget_fact), distinct allow-lists produce
  distinct cache entries.

- test/e2e/cycle-consolidate-postgres.test.ts (3 cases) — Postgres
  parity for the dream-cycle consolidate phase. Mirrors the PGLite
  unit test but exercises the real postgres-engine codepaths: sql.begin
  transactions, advisory locks on insertFact's entity-slug dedup window,
  unsafe('::vector') casts on findCandidateDuplicates ordering,
  addTakesBatch postgres-js unnest path. Happy path (4 facts → 1 take +
  all consolidated_into set), age-threshold skip, dry-run no-write.

All 5 unit + 3 e2e tests pass. Closes the unit-only gap on the
consolidate phase (was only PGLite-tested) and pins meta-cache
invariants the dispatcher depends on.

* v0.31 fix: thread auth + sourceId, JSON-shape every error envelope

Three bugs surfaced during the full e2e sweep that all trace back to my
v0.31 dispatch refactor (D12/eE1) silently dropping auth threading +
non-OperationError exceptions emitting plain strings:

1. **HTTP MCP transport lost ctx.auth.** Refactoring serve-http.ts to call
   dispatchToolCall meant auth had to come through DispatchOpts, but the
   field didn't exist yet. Every HTTP whoami call returned
   `unknown_transport` because ctx.auth was undefined. Added `auth?:
   AuthInfo` to DispatchOpts, plumbed it through buildOperationContext,
   and updated serve-http.ts:816 to pass `auth: authInfo` alongside
   sourceId/takesHoldersAllowList. Pinned by sources-remote-mcp e2e
   `whoami reports oauth transport + sources_admin scope`.

2. **Non-OperationError exceptions emitted plain strings, not JSON.**
   The pre-v0.31 serve-http.ts always wrapped errors in JSON envelope
   `{error, message}`; my dispatch refactor missed the unknown-tool +
   uncaught-throw paths and emitted `Error: ${msg}` text content. Every
   caller that did `JSON.parse(content)` (sources-remote-mcp callMcp
   helper at line 104) crashed with `Unexpected identifier "Error"`.
   Both error paths in dispatchToolCall now return JSON-shaped content
   matching the OperationError pattern.

3. **Files→sources FK silently lost on rewound bootstrap path.**
   test/e2e/postgres-bootstrap.test.ts simulates a pre-v0.21 brain by
   `DROP TABLE IF EXISTS sources CASCADE` which removes
   files_source_id_fkey while leaving files.source_id intact. The v23
   migration's `ALTER TABLE files ADD COLUMN IF NOT EXISTS source_id ...
   REFERENCES sources(id) ON DELETE CASCADE` is a no-op when the column
   exists, so the FK never came back on upgrade — and any sources-remove
   afterward stopped cascading to files. Added a defensive
   `IF NOT EXISTS files_source_id_fkey ... ALTER TABLE ADD CONSTRAINT`
   block inside v23's handler. Pinned by `multi-source — cascade delete
   covers every dependent row` after running postgres-bootstrap.

Plus: src/core/preferences.ts now honors GBRAIN_HOME for
`~/.gbrain/migrations/completed.jsonl`. Without this, the doctor
exits-0 mechanical test inherits the developer machine's stale
partial-migration ledger entries (0.21.0, 0.22.4, 0.28.0, 0.29.1
prior dev work) and surfaces them as the [FAIL] minions_migration check.
GBRAIN_HOME-scoped tempdir per test now isolates this state cleanly.

* v0.31 chore: scrub personal references from public artifacts

Per the CLAUDE.md privacy rule on `Garry's Separation Test`, replace
personally-coded references in v0.31 artifacts with neutral examples:

- CHANGELOG.md v0.31 entry: rename "Garry's Separation Test" header to
  "The cross-session test" + drop the "topic-2659/topic-1941, 7 AM/2 PM,
  flying to Tokyo" narrative.
- src/commands/migrations/v0_31_0.ts feature pitch: same scrub.
- test/facts-separation-pglite.test.ts + test/e2e/facts-separation-postgres.test.ts:
  rename describe blocks; replace specific topic-NNNN session ids with
  session-A / session-B; replace personal sample fact with
  "sample event Tuesday".
- src/core/facts/extract.ts extractor system prompt example slugs:
  people/sam-altman → people/alice-example; companies/anthropic → companies/acme.
- src/core/entities/resolve.ts comment: Sam Altman → Alice Example.
- All v0.31 test fixtures: people/sam → people/alice-example,
  Sam Altman → Alice Example, sam-the-cofounder → alice-the-cofounder.
  Test names referencing real-world entities replaced with neutral slugs.

Pre-existing references to "Garry" elsewhere in CHANGELOG (v0.17, v0.19,
v0.21+ entries) are untouched — that's a separate scope from this v0.31
ship.

Plus: the truncate fix for the Bun-script-induced syntax error in
test/e2e/mechanical.test.ts (cliEnv arrow function had ", 30_000)" tacked
onto its closing brace by the bulk-add-timeouts script — repaired to a
clean function definition).

* v0.31 fix(test): bump E2E phase-count assertions for 11-phase cycle

Two E2E tests still asserted the v0.31 pre-merge 10-phase shape
(consolidate inserted, but recompute_emotional_weight from v0.29 not yet
absorbed). With master's v0.29 work merged in, the cycle is now 11 phases:
lint → backlinks → sync → synthesize → extract → patterns →
recompute_emotional_weight → consolidate → embed → orphans → purge.

- test/e2e/cycle.test.ts: 10 → 11
- test/e2e/dream-cycle-eight-phase-pglite.test.ts: ALL_PHASES + dry-run order

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.31 fix(merge): close brace between v44 and v45 migration objects

The v0.30.2 merge resolution stitched master's v40-v44 migrations onto
HEAD's v45 (facts hot memory) migration but lost the closing `},` between
v44 and v45. tsc caught it as TS1136 Property assignment expected at
migrate.ts:2188.

This is a one-line bracket fix; the rest of the merge resolution is
correct and tests pass.

* v0.31 fix: put_page cliHints + buildPlan v0.31.0 in skippedFuture

Two unit-test failures surfaced after the v0.30.2 merge:

1. operations.ts: put_page had `cliHints: { name: 'put', positional: ['stdin'] }`
   from earlier v0.31 development. The parity test enforces that every name
   in `positional` is a real param. Restored master's correct shape:
   `{ name: 'put', positional: ['slug'], stdin: 'content' }`.

2. test/apply-migrations.test.ts: the H9 regression tests pin the exact
   skippedFuture list. Adding v0.31.0 to the registry meant the list grew
   by one. Updated both `expect(...).toEqual([...])` assertions.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.31 docs: clarify consolidate is 11th phase + regen llms-full.txt

CHANGELOG.md narrative said "new 10th phase consolidate"; with v0.29's
recompute_emotional_weight already on master, consolidate is the 11th phase
(between recompute and embed). Schema migration is v45, not v40, after the
merge resolution renumbered it to clear master's v40-v44.

llms-full.txt regenerated to reflect the README's 11-phase dream-cycle
phrasing (the build-llms test enforces commit-time parity).

 		410c6978a4 v0.30.2 feat: dream synthesize stops dropping fat transcripts (#754) 
* feat: classify Anthropic prompt-too-long as UnrecoverableError

The subagent handler now detects 400 "prompt is too long" responses
from the Anthropic SDK and rethrows as UnrecoverableError. The worker
already routes UnrecoverableError straight to `dead`, so doomed jobs
fail terminally on first attempt instead of stalling 3x with the same
oversized prompt.

isPromptTooLongError matches the production message verbatim
("prompt is too long: N tokens > N maximum"), case-insensitive, on
both the outer message and inner error.message paths. Defensive
secondary match for status=400 + invalid_request_error/request_too_large
with the words "too long"/"exceed"/"maximum".

9 unit cases pin the detection: production wording, case folding,
nested SDK shape, defensive 400 paths, unrelated 400s, transient
errors, null/empty inputs.

* feat: model-aware chunking + slug-rewrite for dream synthesize

The synthesize phase now chunks oversized transcripts at paragraph
boundaries instead of submitting one giant prompt that 400s on
Anthropic. Closes the v0.30 dream-cycle queue clog where 1.7M-token
transcripts dead-lettered after 3 stalls and re-discovered every
cycle.

D1: per-chunk budget = floor(model_context_tokens × 0.9 × 3.5).
MODEL_CONTEXT_TOKENS keys on resolved Anthropic ids (Opus 4.7 = 1M,
Sonnet 4.6 = 200K, Haiku = 200K). Non-Anthropic models fall back to
180K-token safe default with a once-per-process stderr warning.
dream.synthesize.max_prompt_tokens overrides the model lookup
(token-shaped, name from PR #748, floor 100K).

D5: on max_chunks_per_transcript cap hit, log + skip; do NOT write to
dream_verdicts. Closes the cache-poisoning class — next cycle
re-attempts under whatever budget is then current.

D6: orchestrator-side deterministic slug rewrite, zero Sonnet trust.
collectChildPutPageSlugs raw-fetches every (job_id, slug) pair (no
SELECT DISTINCT — that erased the collision evidence the audit
claimed to detect) and rewrites bare-hash6 slugs to <hash6>-c<idx>
for chunked children.

D8: pre-fan-out lookup of completed legacy `dream:synth:<filePath>:
<hash16>` jobs. Transcripts already synthesized under the
single-chunk shape skip submission with `already_synthesized_legacy_
single_chunk` instead of resubmitting under chunked keys.

D9: hash-deterministic chunk boundaries. The 3-tier ladder lifted
from PR #748 (## Topic: > --- > nearest \\n) is fed a back-half
search-window offset derived from contentHash. Same content always
chunks identically across runs; chunk N of a previously-failed
transcript produces byte-identical content on retry.

D10: 24-chunk default cap, operator-configurable via
dream.synthesize.max_chunks_per_transcript.

18 unit cases pin the chunker (boundary ladder, hash determinism,
hard fallback, slug rewrite all 7 shapes). 4 PGLite E2E cases pin
fan-out shape (single-chunk legacy key parity, multi-chunk chunked
key shape) + skip paths (D5 cap hit no verdict-cache write, D8
legacy-key skip).

Credits PR #748 (Wintermute) for the boundary ladder, config key
naming, and 3.5 chars/token estimator. This branch supersedes #748
with the structural safeguards (model-aware budget, terminal-error
classify, slug rewrite, hash-determinism, doctor surfacing).

* feat: surface dead-lettered prompt_too_long jobs in doctor queue_health

queue_health gains a 4th subcheck counting dead `subagent` jobs in
the last 24h whose error_text starts with `prompt_too_long:`. When
present, prints a fix hint pointing at
`gbrain dream --phase synthesize --dry-run --json` to identify the
fat transcripts and naming the two operator escape hatches
(`dream.synthesize.max_prompt_tokens` for budget tuning,
larger-context model for capacity).

Operators now see the chunking failure mode without grepping
minion_jobs by hand.

- README dream help: 8-phase → 9-phase, mention v0.30.2 chunking + config keys
- CLAUDE.md synthesize.ts: chunker + per-chunk idempotency + D6 slug rewrite + D7 scope + D8 legacy-key
- CLAUDE.md subagent.ts: prompt_too_long terminal classification
- CLAUDE.md doctor.ts: queue_health subcheck 4 (dead-lettered prompt_too_long)

* docs: regenerate llms-full.txt after v0.30.2 CLAUDE.md updates

The docs/ pass extended three Key Files entries in CLAUDE.md
(synthesize.ts, subagent.ts, doctor.ts). The auto-derived
llms-full.txt bundle picks up those CLAUDE.md changes via
build-llms; the build-llms test caught the drift in CI.

 		b8e0a0eada v0.29.0 + v0.29.1 feat: salience + anomaly detection — brain surfaces what's hot without being asked (#730) 
* v0.29 foundation: emotional_weight column + formula + anomaly stats

Migration v34 adds pages.emotional_weight REAL DEFAULT 0.0 (column-only,
no index — salience query orders by computed score, not raw weight).
Embedded DDL (schema.sql + pglite-schema.ts + schema-embedded.ts)
mirrors the column so fresh installs don't need migration replay.

types.ts gains: PageFilters.sort enum + PAGE_SORT_SQL whitelist (engines
hardcoded ORDER BY updated_at DESC; threading lands in the next commit);
SalienceOpts/SalienceResult, AnomaliesOpts/AnomalyResult,
EmotionalWeightInputRow/EmotionalWeightWriteRow contracts.

cycle/emotional-weight.ts: pure-function score in [0..1] from tags +
takes (anglocentric default seed list; user-overridable via config key
emotional_weight.high_tags). cycle/anomaly.ts: meanStddev + cohort
threshold helpers with zero-stddev fallback (count > mean + 1) so rare
cohorts don't produce NaN sigmas.

Test coverage: migrate v34 structural assertions + 14-case formula
unit + 13-case anomaly stats unit. Codex review fixes baked in:
formula clamped to [0,1]; per-take weight clamped to [0,1] before
averaging; zero-stddev fallback finite, never NaN.

* v0.29 engine: batch emotional-weight methods + listPages sort

BrainEngine adds 4 methods, both engines implement:

- batchLoadEmotionalInputs(slugs?): CTE-shaped read with per-table
  pre-aggregates. A page with N tags + M takes never produces N×M rows
  (codex C4#4) — page_tags + page_takes CTEs aggregate independently,
  then LEFT JOIN to pages.

- setEmotionalWeightBatch(rows): UPDATE FROM unnest($1::text[],
  $2::text[], $3::real[]) composite-keyed on (slug, source_id). Multi-
  source brains can't fan out (codex C4#3) — pages.slug is unique only
  within source_id. Same shape that v0.18 link batches use.

- getRecentSalience: time boundary computed in JS, bound as TIMESTAMPTZ.
  SQL identical across engines (codex C5/D5 — avoids dialect drift on
  $1::interval binding which has zero current uses on PGLite).

- findAnomalies: tag + type cohort baselines via generate_series-
  densified daily-count CTEs (codex C4#6). Sparse-day rare cohorts get
  correct (mean, stddev) instead of biased upward by zero-omission.
  Year cohort deferred to v0.30.

listPages threads the new PageFilters.sort enum through both engines.
Was hardcoded ORDER BY updated_at DESC; now PAGE_SORT_SQL whitelist
maps the 4 enum values to literal SQL fragments — no injection surface.
postgres.js uses sql.unsafe; PGLite splices the fragment directly.

Regression tests (PGLite, no DATABASE_URL needed):

- multi-source-emotional-weight: same slug under two source_ids,
  setEmotionalWeightBatch on one of them, asserts the other survives
  untouched. Direct codex C4#3 guard.

- list-pages-regression (IRON RULE): old call shape (type, tag, limit)
  still returns updated_desc default; new sort=updated_asc reverses;
  sort=created_desc orders by created_at; sort=slug alphabetical;
  unsupported sort enum falls back to default (defense in depth).

* v0.29 cycle: new recompute_emotional_weight phase

Adds a 9th cycle phase between extract and embed. Sees the union of
syncPagesAffected + synthesizeWrittenSlugs for incremental mode (so
synthesize-written pages get their weight computed too — codex C2 caught
that the prior plan threaded only sync). Full mode (no incremental
anchors) walks every page; users hit this path on first upgrade via
gbrain dream --phase recompute_emotional_weight.

Phase orchestrator (cycle/recompute-emotional-weight.ts) is two SQL
round-trips total regardless of brain size:
  1. batchLoadEmotionalInputs(slugs?) → per-page tag/take inputs.
  2. computeEmotionalWeight in memory (pure function).
  3. setEmotionalWeightBatch(rows) → composite-keyed UPDATE FROM unnest.

Empty affectedSlugs short-circuits (no DB read, no write). Dry-run
computes weights and reports the would-write count without touching
the DB. Engine throw bubbles into status:fail with code
RECOMPUTE_EMOTIONAL_WEIGHT_FAIL — cycle continues to the next phase.

Plumbing:
- CyclePhase type adds 'recompute_emotional_weight'.
- ALL_PHASES + NEEDS_LOCK_PHASES include it.
- CycleReport.totals adds pages_emotional_weight_recomputed (additive,
  schema_version stays "1").
- runCycle's totals rollup + status derivation honor the new field.
- synthesize.ts emits writtenSlugs in details so cycle.ts can union
  with syncPagesAffected for incremental backfill.

Tests: 7-case unit (fake-engine), 3-case PGLite e2e (full mode + dry-
run + ALL_PHASES position), 1000-page perf budget (<5s on PGLite).

Codex C2 → A: clean separation. Phase doesn't modify runExtractCore;
runs on its own seam after the existing 8 phases plus synthesize.

* v0.29 ops: get_recent_salience + find_anomalies + get_recent_transcripts

Three new MCP operations + a transcripts library:

- get_recent_salience: pages ranked by emotional + activity salience.
  Subagent-allow-listed. params: days (default 14), limit (default 20,
  capped 100), slugPrefix (renamed from `kind` per codex C4#10 to
  avoid collision with PageKind/TakeKind).

- find_anomalies: cohort-level activity outliers (tag + type).
  Subagent-allow-listed. Year cohort deferred to v0.30.

- get_recent_transcripts: raw .txt transcripts from the dream-cycle
  corpus dirs. LOCAL-ONLY: rejects ctx.remote === true with
  permission_denied (codex C3). NOT in the subagent allow-list — all
  subagent calls run with remote=true, would always reject (footgun if
  visible). Cycle's synthesize phase calls discoverTranscripts
  directly, so subagents that need transcripts go through the library
  function, not the op.

Tool descriptions extracted to src/core/operations-descriptions.ts so
they're pinnable in tests and stable for the Tier-2 LLM routing eval.
Redirects on query/search/list_pages: personal/emotional questions
should reach the new ops, not semantic search. Anti-flattery hint on
query: "Do NOT assume words like crazy, notable, or big mean
impressive — they often mean difficult or emotionally charged."

list_pages gains updated_after (string ISO) and sort enum params,
surfacing the engine threading from the prior commit.

src/core/transcripts.ts: filesystem walk shared by the gated MCP op
and the (commit 5) CLI command. Reuses discoverTranscripts corpus-dir
resolution + isDreamOutput from cycle/transcript-discovery.ts. Trust
gate lives in the op handler, not the library — the library is
trusted by both the gated op and the local CLI.

Allow-list: 11 → 13 (add salience + anomalies; transcripts excluded
per codex C3, with a comment explaining why).

Tests: 21-case description pin (catches accidental edits that change
LLM-facing surface); 11-case transcripts unit covering trust gate,
mtime window, dream-output skip, summary truncation, no corpus_dir;
2-case salience type-contract smoke (full Garry-test fixture in commit
6's e2e suite).

Codex C1: routing-eval fixtures (skills/<x>/routing-eval.jsonl)
deliberately NOT shipped — routing-eval.ts is substring-match on
resolver triggers, not MCP tool routing. Real coverage lands as
test/e2e/salience-llm-routing.test.ts in commit 6.

* v0.29 CLI: gbrain salience / anomalies / transcripts

Three new CLI commands wired into src/cli.ts dispatch + CLI_ONLY set +
help text:

- gbrain salience [--days N] [--limit N] [--kind PREFIX] [--json]
- gbrain anomalies [--since YYYY-MM-DD] [--lookback-days N] [--sigma N] [--json]
- gbrain transcripts recent [--days N] [--full] [--json]

Each command file mirrors src/commands/orphans.ts shape: pure data fn
+ JSON formatter + human formatter. Calls into engine.getRecentSalience
/ findAnomalies (already shipped) and src/core/transcripts.ts.

salience and anomalies show ranked rows with per-cohort
mean/stddev/sigma. transcripts honors `--full` (caps at 100KB/file)
vs default summary (first non-empty line + ~250 chars). All three
emit JSON with --json for agent consumption.

`--kind` is accepted as a slug-prefix shorthand on `gbrain salience`
even though the underlying op param is `slugPrefix` (kept the CLI
flag short; the MCP-facing param uses the more-explicit name to
align with PageKind/TakeKind/slugPrefix vocabulary).

CLI_ONLY set in src/cli.ts gains the three new command names so
they don't get forwarded to MCP-only routing.

* v0.29 e2e: Garry-test fixtures + Postgres parity + LLM routing eval

PGLite e2e (no DATABASE_URL needed):

- salience-pglite: the Garry test. 7 wedding-tagged pages updated today
  + 100 background pages backdated across 30 days via raw SQL UPDATE
  (codex C4#7 — engine.putPage stamps updated_at = now(), so seeding
  via the engine alone can't reproduce historical recency windows).
  Asserts wedding pages outrank random-tag noise in the 7-day window;
  slugPrefix filter narrows correctly; days=0 boundary case; limit cap.

- anomalies-pglite: same fixture shape (7 wedding pages today, 100
  background backdated). findAnomalies with sigma=3 returns the
  wedding-tag cohort with sigma_observed > 3 vs near-zero baseline;
  page_slugs sample carries the wedding pages; date with no activity
  returns []; high sigma threshold suppresses borderline cohorts
  (zero-stddev fallback stays finite — no NaN sigma).

Postgres-gated e2e:

- engine-parity-salience: PGLite ↔ Postgres parity for getRecentSalience
  and findAnomalies. Same fixture into both engines; top-result and
  cohort-set match. Closes the v0.22.0-style parity gap for the new
  v0.29 SQL idioms (EXTRACT(EPOCH ...), generate_series, CTE chain).

Tier-2 LLM routing eval (ANTHROPIC_API_KEY-gated):

- salience-llm-routing: calls Claude with v0.29 tool descriptions and
  12 personal-query phrasings ("anything crazy lately", "what's been
  going on with me", etc.). Asserts the chosen tool is in the v0.29
  set, not query() / search(). ~$0.10 per CI run on Haiku. Tests the
  ACTUAL ship criterion — replaces the discarded fake-coverage
  routing-eval.jsonl fixtures (codex C1 → B).

This is the only test that proves the description edits drive routing.
Without it, we'd ship description changes and only learn from
production behavior.

* v0.29.0: ship-prep — VERSION + CHANGELOG + CLAUDE Key Files

VERSION + package.json bump 0.28.0 → 0.29.0.

CHANGELOG.md adds a v0.29.0 release-summary in the GStack/Garry voice
plus the "To take advantage of v0.29.0" block. Headline two-liner:
"The brain tells you what's hot without being asked. Salience +
anomaly detection ship. Search rewards hypotheses; salience surfaces
them." Numbers-that-matter table covers engine surface delta, MCP op
delta, allow-list delta, cycle-phase delta, schema migration, list_pages
param surface, and test count. Itemized changes section lists the
schema migration + new cycle phase + new MCP ops + redirect
descriptions + subagent allow-list rules + new tests + a contributor
note clarifying that routing-eval.ts is not the right surface for
testing MCP tool routing (use the Tier-2 LLM eval pattern instead).

CLAUDE.md Key Files updated for the v0.29 surface:

- src/core/engine.ts: notes the 4 new methods + PageFilters.sort threading.
- src/core/migrate.ts: v34 (pages_emotional_weight) entry.
- src/core/cycle.ts: 8 → 9 phases, recompute_emotional_weight inserted
  between patterns and embed; totals.pages_emotional_weight_recomputed.
- src/core/cycle/emotional-weight.ts (NEW): formula + override path.
- src/core/cycle/anomaly.ts (NEW): stats helpers + zero-stddev fallback.
- src/core/cycle/recompute-emotional-weight.ts (NEW): phase orchestrator.
- src/core/transcripts.ts (NEW): library shared by gated MCP op + CLI.
- src/core/operations-descriptions.ts (NEW): pinned tool descriptions.
- src/core/minions/tools/brain-allowlist.ts: 11 → 13 entries; comment
  on why get_recent_transcripts is excluded.
- src/commands/salience.ts / anomalies.ts / transcripts.ts (NEW): CLI surface.

* v0.29.1 feat: recency + salience as two orthogonal options on query op (#696)

* feat: recency boost for search (v0.27.0) — temporal intent auto-detection, date filters, configurable decay

New search pipeline stage: keyword + vector → RRF → cosine re-score → backlink boost → recency boost → dedup

- applyRecencyBoost: hyperbolic decay, two strengths (moderate 30-day halflife, aggressive 7-day halflife)
- Auto-enabled when intent.ts detects temporal/event queries (detail='high')
- Manual override via SearchOpts.recencyBoost (0/1/2)
- Date filtering: afterDate/beforeDate on all three search paths (keyword, keywordChunks, vector)
- getPageTimestamps on both Postgres and PGLite engines
- 15 tests passing (boost math + intent classification)

* v0.29.1 schema: pages.{effective_date, effective_date_source, import_filename, salience_touched_at} + expression index

Migration v38 adds 4 nullable columns to pages and an expression index on
COALESCE(effective_date, updated_at) to support the new since/until date
filters. All additive — no behavior change in the default search path; only
consulted when callers opt into the new salience='on' / recency='on' axes
or pass since/until.

  effective_date         — content date (event_date / date / published /
                           filename-date / fallback). Read by recency boost
                           and date-filter paths only. Auto-link doesn't
                           touch it (immune to updated_at churn).
  effective_date_source  — sentinel for the doctor's effective_date_health
                           check ('event_date' | 'date' | 'published' |
                           'filename' | 'fallback').
  import_filename        — basename without extension, captured at import.
                           Used for filename-date precedence on daily/,
                           meetings/. Older rows leave it NULL.
  salience_touched_at    — bumped by recompute_emotional_weight when
                           emotional_weight changes. Salience window uses
                           GREATEST(updated_at, salience_touched_at) so
                           newly-salient old pages enter the recent salience
                           query.

Index strategy: a partial index on effective_date alone wouldn't help the
COALESCE expression in since/until filters (planner can't use it for the
negative side). The expression index ((COALESCE(effective_date, updated_at)))
is what actually accelerates the filter.

Postgres uses CONCURRENTLY + v14-style pg_index.indisvalid pre-drop guard
for prior failed CONCURRENTLY runs; PGLite uses plain CREATE INDEX. Mirror
of v34's pattern.

src/schema.sql + src/core/pglite-schema.ts updated for fresh installs;
src/core/schema-embedded.ts regenerated via bun run build:schema.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.29.1: computeEffectiveDate helper + putPage integration

Pure helper computing a page's effective_date from frontmatter precedence:
  1. event_date (meeting/event pages)
  2. date (dated essays)
  3. published (writing/)
  4. filename-date (leading YYYY-MM-DD in basename)
  5. updated_at (fallback)
  6. created_at (last resort)

Per-prefix override: for daily/ and meetings/ slugs, filename-date jumps
to position 1 — the filename is the user's primary signal there.

Returns {date, source}. The source label powers the doctor's
effective_date_health check to detect "fell back to updated_at" rows that
look populated but are functionally a NULL.

Range validation: parsed value must be in [1990-01-01, NOW + 1 year].
Out-of-range values drop to the next chain element.

Wired into importFromContent + importFromFile. The put_page MCP op derives
filename from slug-tail when no caller-supplied filename is available.

putPage SQL on both engines extended to write the new columns. ON CONFLICT
uses COALESCE(EXCLUDED.x, pages.x) so callers that don't know about the
new columns (auto-link, code reindex) preserve existing values rather than
blanking them. SELECT projection extended to return them; rowToPage threads
them through.

21 unit tests covering: precedence chain default order, per-prefix override,
parse failure fall-through, range validation [1990, NOW+1y], parseDateLoose
shape variants. All pass; typecheck clean.

* v0.29.1: backfill orchestrator + library function for existing pages

src/core/backfill-effective-date.ts is the shared library function. Walks
pages in keyset-paginated batches (id > last_id ORDER BY id LIMIT 1000),
runs computeEffectiveDate per row, UPDATEs effective_date +
effective_date_source. Resumable via the `backfill.effective_date.last_id`
checkpoint key in the config table — a killed process can re-run and pick
up without re-doing rows. Idempotent: a full re-walk produces the same
writes.

Postgres-only: SET LOCAL statement_timeout = '600s' per batch. Doesn't
refuse the migration on low session settings (codex pass-2 #16).

src/commands/migrations/v0_29_1.ts is the orchestrator (4 phases mirroring
v0_12_2). Phase A schema (gbrain init --migrate-only), Phase B backfill
(via the library function), Phase C verify (count NULL effective_date),
Phase D record (handled by runner). The library function is reusable from
the gbrain reindex-frontmatter CLI command in the next commit.

import_filename stays NULL for backfilled rows — pre-v0.29.1 imports
didn't capture it. computeEffectiveDate uses the slug-tail when filename
is NULL; daily/2024-03-15 backfilled gets effective_date from the slug.

Registered in src/commands/migrations/index.ts.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.29.1: gbrain reindex-frontmatter CLI command

Recovery / explicit-rebuild path for pages.effective_date. Used when:
  - User edited frontmatter dates after import
  - Post-upgrade backfill orchestrator finished but the user wants to
    re-walk a subset (e.g. just meetings/) after fixing some frontmatter
  - Precedence rules change between releases

Thin wrapper over backfillEffectiveDate from commit 3 — same code path
the v0_29_1 orchestrator uses; one source of truth.

Flags mirror reindex-code:
  --source <id>      Scope to one sources row (placeholder; library
                     library doesn't filter by source today, tracked v0.30+)
  --slug-prefix P    Scope to slugs starting with P (e.g. 'meetings/')
  --dry-run          Print what WOULD change, no DB writes
  --yes              Skip confirmation prompt (required for non-TTY non-JSON)
  --json             Machine-readable result envelope
  --force            Re-apply even when computed value matches existing

Wired into src/cli.ts. CLI handles its own engine lifecycle (creates +
disconnects).

* v0.29.1: recency-decay map + buildRecencyComponentSql (pure, unused)

src/core/search/recency-decay.ts mirrors source-boost.ts in shape but
drives RECENCY ONLY (per D9 codex resolution). Salience is a separate
orthogonal axis; this map does not feed it.

DEFAULT_RECENCY_DECAY: 10 generic prefixes (no fork-specific names).
  - concepts/      evergreen (halflifeDays=0)
  - originals/     180d × 0.5 (long-tail decay; new essays nudged)
  - writing/       365d × 0.4
  - daily/         14d × 1.5  (aggressive — freshness IS the signal)
  - meetings/      60d × 1.0
  - chat/          7d × 1.0
  - media/x/       7d × 1.5
  - media/articles/ 90d × 0.5
  - people/companies/ 365d × 0.3
  - deals/         180d × 0.5

DEFAULT_FALLBACK: 90d × 0.5 for unmatched slugs.

Override priority: defaults < gbrain.yml recency: < env (GBRAIN_RECENCY_DECAY)
< per-call SearchOpts.recency_decay.

parseRecencyDecayEnv format: comma-separated prefix:halflifeDays:coefficient
triples. Refuses LOUD on parse error (RecencyDecayParseError) — codex
pass-2 #M3 finding. No silent fallback like source-boost's parser.

parseRecencyDecayYaml takes already-parsed YAML; throws on bad shape.

buildRecencyComponentSql in sql-ranking.ts emits a CASE expression with
longest-prefix-first ordering, evergreen short-circuit (literal 0 when
halflifeDays=0 or coefficient=0), and EXTRACT(EPOCH ...) for non-zero
branches. Output: ((CASE WHEN p.slug LIKE 'daily/%' THEN 1.5 * 14.0 /
(14.0 + EXTRACT(EPOCH FROM (NOW() - <dateExpr>))/86400.0) ... END))

Typed NowExpr enum prevents SQL injection (codex pass-1 #5). Tests pass
{ kind: 'fixed', isoUtc } for deterministic output; production NOW().
The 'fixed' branch escapes single quotes via escapeSqlLiteral.

25 unit tests covering: env parser shape, env error cases, yaml parser
shape, merge precedence (defaults < yaml < env < caller), CASE longest-
prefix-first ordering, evergreen short-circuit, NowExpr fixed/now,
single-quote injection defense, empty decayMap fallback path, default
map composition (no fork names, concepts/ evergreen, daily/ aggressive).

Pure module. Zero consumers in this commit; commit 6 wires it into
getRecentSalience, commit 10 wires it into the post-fusion stage.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.29.1: refactor getRecentSalience to consume buildRecencyComponentSql

Both engines (Postgres + PGLite) now build the salience formula's third
term via buildRecencyComponentSql instead of inlining 1.0 / (1 + days_old).
Parameters: empty decayMap + fallback { halflifeDays: 1, coefficient: 1.0 }.
Math expands to 1 * 1.0 / (1.0 + days_old) = 1 / (1 + days_old) — same
numeric output as v0.29.0.

This is a no-behavior-change refactor preparing for commit 7's recency_bias
param. recency_bias='flat' (default) reproduces v0.29.0 exactly; 'on'
swaps in DEFAULT_RECENCY_DECAY for per-prefix decay.

Single source of truth for the recency math: same builder feeds the
salience query AND (in commit 10) the post-fusion applyRecencyBoost stage.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v0.29.1: get_recent_salience gains recency_bias param (default 'flat')

SalienceOpts.recency_bias: 'flat' | 'on' added; default 'flat' preserves
v0.29.0 ranking verbatim. Pass 'on' to opt into per-prefix decay map
(concepts/originals/writing/ evergreen; daily/, media/x/, chat/ aggressive
decay).

When recency_bias='on', the salience query reads
COALESCE(p.effective_date, p.updated_at) instead of bare p.updated_at, so
the recency component is immune to auto-link updated_at churn — old
concepts/ pages just-touched by auto-link don't suddenly look fresh.

Both engines (Postgres + PGLite) wire the param through. resolveRecencyDecayMap()
honors gbrain.yml + GBRAIN_RECENCY_DECAY env at runtime.

MCP op surface: get_recent_salience gains the param with a load-bearing
description teaching the agent when to use 'on' vs 'flat' (current state →
on; mattering across all time → flat).

No silent v0.29.0 behavior change — opt-in only (per D11 codex resolution).

* v0.29.1: recompute_emotional_weight writes salience_touched_at; window picks up newly-salient pages

setEmotionalWeightBatch on both engines now bumps salience_touched_at to
NOW() ONLY when the new emotional_weight differs from the existing one
(IS DISTINCT FROM, NULL-safe). No-op writes (same weight) leave the
column alone — preserves "actual change" semantics.

getRecentSalience window changes from
  WHERE p.updated_at >= boundary
to
  WHERE GREATEST(p.updated_at, COALESCE(p.salience_touched_at, p.updated_at)) >= boundary

Closes codex pass-1 finding #4: pages whose emotional_weight just changed
in the dream cycle (because tags or takes shifted) but whose updated_at
is older than the salience window now correctly enter the recent-salience
results. Without this, "Garry just added a take to a 6-month-old page"
stayed invisible to get_recent_salience until the next content edit.

COALESCE(salience_touched_at, p.updated_at) handles pre-v0.29.1 rows
where salience_touched_at is NULL — they fall back to p.updated_at and
behave identically to v0.29.0.

* v0.29.1: merge intent.ts → query-intent.ts; emit 3 suggestions per query

D1 + D4 + D6 + D8: single regex-pass classifier returning
{intent, suggestedDetail, suggestedSalience, suggestedRecency}.

intent + suggestedDetail are v0.29.0 behavior verbatim (legacy intent.ts
deleted; classifyQueryIntent + autoDetectDetail compat shims preserved).

NEW for v0.29.1 — two orthogonal recency-axis suggestions:

  suggestedSalience: 'off' | 'on' | 'strong'
  suggestedRecency:  'off' | 'on' | 'strong'

Resolution rules (per D6 narrow temporal-bound exception):
  - CANONICAL patterns (who is X / what is Y / code / graph) → both off
  - UNLESS an EXPLICIT_TEMPORAL_BOUND also matches (today / right now /
    this week / since X / last N days), in which case temporal-bound wins
  - STRONG_RECENCY (today / right now / this morning / just now) → strong
  - RECENCY_ON (latest / recent / this week / meeting prep / catch up
    / remind me / status update) → on
  - SALIENCE_ON (catch up / remind me / status update / prep me /
    what's going on / what matters) → on
  - default → off for both axes (v0.29.1 prime-directive: pure opt-in)

Salience and recency are TRULY orthogonal (per D9). A query like
"latest news on AI" → recency='on' but salience='off' (the user wants
fresh, not emotionally-weighted). "What's going on with widget-co" →
both on. "Who is X right now" → both 'strong'/'on' (temporal bound
beats canonical 'who is').

intent.ts deleted; test/intent.test.ts renamed → test/query-intent-legacy.test.ts
(unchanged behavior coverage). New test/query-intent.test.ts adds 21
cases covering all three axes' interactions: canonical wins on bare
'who is', temporal bound overrides, "catch me up" matches with up to 15
chars between, "today" → strong, intent vs recency independence.

Updated callers:
  - src/core/search/hybrid.ts (autoDetectDetail import)
  - test/recency-boost.test.ts (classifyQueryIntent import)
  - test/benchmark-search-quality.ts (autoDetectDetail import)

* v0.29.1: applySalienceBoost + applyRecencyBoost + runPostFusionStages wrapper

D9 + codex pass-1 #2 + #3 + pass-2 #4: salience and recency are TRULY
ORTHOGONAL post-fusion stages, both running from ALL THREE hybridSearch
return paths (keyword-only, embed-failure-fallback, full-hybrid).

NEW src/core/search/hybrid.ts exports:
  - applySalienceBoost(results, scores, strength)
      score *= 1 + k * log(1 + score) where k = 0.15 (on) or 0.30 (strong)
      No time component. Pure mattering signal.
  - applyRecencyBoost(results, dates, strength, decayMap, fallback, nowMs?)
      Per-prefix decay factor: 1 + strengthMul * coefficient * halflife / (halflife + days_old)
      strengthMul: 1.0 (on) or 1.5 (strong)
      Evergreen prefixes (halflifeDays=0) skipped (factor 1.0).
      Pure recency signal. Independent of mattering.
  - runPostFusionStages(engine, results, opts)
      Wraps backlink + salience + recency. Called from EACH return path so
      keyless installs and embed failures get the same boost surface as
      the full hybrid path.

NEW engine methods (composite-keyed for multi-source isolation):
  - getEffectiveDates(refs: Array<{slug, source_id}>): Map<key, Date>
      Returns COALESCE(effective_date, updated_at, created_at). Key format:
      `${source_id}::${slug}`. Mirror of getBacklinkCounts shape.
  - getSalienceScores(refs: Array<{slug, source_id}>): Map<key, number>
      Returns emotional_weight × 5 + ln(1 + take_count). Composite key.

Deprecated (kept for back-compat through v0.29.x):
  - SearchOpts.afterDate / beforeDate (alias for since/until)
  - SearchOpts.recencyBoost: 0|1|2 (alias for recency: 'off'|'on'|'strong')
  - getPageTimestamps (use getEffectiveDates instead)

NEW SearchOpts fields:
  - salience: 'off' | 'on' | 'strong'
  - recency:  'off' | 'on' | 'strong'
  - since:    string (ISO-8601 or relative, replaces afterDate)
  - until:    string (replaces beforeDate)

Resolution: caller-explicit > legacy alias (recencyBoost) > heuristic
(classifyQuery's suggestedSalience / suggestedRecency).

Deleted: src/core/search/recency.ts (PR #618's, replaced) +
test/recency-boost.test.ts (its scope is replaced by query-intent.test.ts +
future post-fusion tests).

* v0.29.1: query op gains salience + recency + since + until params; PGLite since/until parity

Combines commits 12 + 13 of the plan.

Query op surface (src/core/operations.ts):
  - salience: 'off' | 'on' | 'strong' (with load-bearing description)
  - recency:  'off' | 'on' | 'strong'
  - since:    string (ISO-8601 or relative; replaces deprecated afterDate)
  - until:    string (replaces deprecated beforeDate)

Tool descriptions teach the calling agent:
  - salience axis = mattering, no time component
  - recency axis = age decay, no mattering signal
  - omit either to let gbrain auto-detect from query text via classifyQuery

hybrid.ts maps since/until → afterDate/beforeDate at the engine call
boundary so PR #618's existing engine plumbing keeps working without
rename. Codex pass-1 #10 finding closed.

PGLite engine (codex pass-1 #10): since/until parity added to all three
search methods (searchKeyword, searchKeywordChunks, searchVector). SQL
filter against COALESCE(p.effective_date, p.updated_at, p.created_at)
so date filtering matches user content-date intent (a meeting was on
event_date, not when it got reimported). Filter is applied INSIDE the
HNSW inner CTE in searchVector so HNSW's candidate pool already
excludes out-of-range pages — preserves pagination contract.

This also closes existing cross-engine drift: pre-v0.29.1 Postgres had
afterDate/beforeDate from PR #618; PGLite had nothing.

* v0.29.1: migration v39 — eval_candidates capture columns for replay reproducibility

D11 codex pass-2 resolution: extend eval_candidates with 7 new nullable
columns so `gbrain eval replay` can reproduce captured runs of agent-explicit
salience + recency choices.

Without these columns, replays of the new axis params drift. The live
behavior depends on the resolved {salience, recency} values; v0.29.0's
schema doesn't capture them.

  as_of_ts            TIMESTAMPTZ  — brain's logical NOW at capture
                                     (replay uses this instead of wall-clock)
  salience_param      TEXT         — what the caller passed (NULL if omitted)
  recency_param       TEXT         — same
  salience_resolved   TEXT         — final value applied
  recency_resolved    TEXT         — same
  salience_source     TEXT         — 'caller' or 'auto_heuristic'
  recency_source      TEXT         — same

All nullable + additive. Pre-v0.29.1 rows stay valid. NDJSON
schema_version STAYS at 1 — consumers ignore unknown fields (codex
pass-1 #C2 dissolves; no cross-repo coordination needed).

ADD COLUMN with no DEFAULT is metadata-only on PG 11+ and PGLite —
instant on tables of any size.

src/schema.sql + src/core/pglite-schema.ts mirror the additions for fresh
installs; src/core/schema-embedded.ts regenerated. eval_capture.ts
populates the new fields in commit 16 (docs + ship).

* v0.29.1: doctor checks — effective_date_health + salience_health

effective_date_health: sample-1000 scan detects three classes of
problems (codex pass-1 #5 resolution via the effective_date_source
sentinel column added in commit 1):

  fallback_with_fm_date  — page fell back to updated_at even though
                           frontmatter has parseable event_date / date /
                           published. The "wrong but populated" residual
                           that earlier review iterations missed.
  future_dated            — effective_date > NOW() + 1 year (corrupt
                            or typo'd century).
  pre_1990                — effective_date < 1990-01-01 (epoch math gone
                            wrong, bad parse).

Sample of last 1000 pages by default — fast on 200K-page brains. Fix
hint: gbrain reindex-frontmatter.

salience_health: detects pages with active takes whose emotional_weight
is still 0 (recompute_emotional_weight phase hasn't run since the
take landed). Reports the brain's non-zero emotional_weight count as
an informational baseline. Fix hint: gbrain dream --phase
recompute_emotional_weight.

Both checks gracefully skip on pre-v0.29.1 brains (column doesn't
exist → 42703) without surfacing as warnings.

* v0.29.1: docs + skills convention + CHANGELOG + version bump

- VERSION 0.29.0 → 0.29.1
- package.json version bump
- CHANGELOG.md: full release-summary + itemized + "To take advantage"
  block per the project's voice rules. Two-line headline + concrete
  pathology framing (existing callers unchanged; new axes opt-in;
  agent in charge per the prime directive).
- skills/conventions/salience-and-recency.md: agent-readable decision
  rules. "Current state → on. Canonical truth → off." plus the narrow
  temporal-bound exception. Cross-cutting convention propagates to
  brain skills via RESOLVER.md.
- skills/migrations/v0.29.1.md: agent-readable upgrade instructions.
  Verify steps + behavior-change reference + recovery commands.

The build-time tool-description generator from D2 (extract decision
tables from skills/conventions/salience-and-recency.md, embed into
operations.ts at build time) is deferred to a follow-up commit. The
tool descriptions on the query op + get_recent_salience are inline in
operations.ts for v0.29.1; the auto-gen + CI staleness gate land in
v0.29.2 if drift becomes a problem in practice.

148 unit tests pass across the v0.29.1 surface (effective-date,
recency-decay, query-intent, migrate, salience, recompute-emotional-weight).

* v0.29 master-rebase fixups: renumber + drift cleanup

- v0.29.1 migrations renumber v38/v39 → v41/v42 (master shipped takes_table at
  v37 + access_tokens_permissions at v38; v0.27.1 took v39). My v0.29.0
  emotional_weight slots in at v40; v0.29.1's pages_recency_columns lands at
  v41 and eval_candidates_recency_capture at v42.
- src/core/utils.ts comment refs updated v37 → v40 (emotional_weight) and
  v38 → v41 (effective_date/etc).
- test/brain-allowlist.test.ts: size assertion 11 → 13 + the new
  get_recent_salience / find_anomalies positive checks + the explicit
  get_recent_transcripts negative check (v0.29 added the salience pair to
  the allow-list; transcripts are deliberately excluded because all
  subagent calls have remote=true and the v0.29 trust gate rejects them —
  visibility would be a footgun).

* v0.29 CI fixups: privacy allow-list + cycle phase count + migration plan

Three CI test failures on PR #730, all caused by master-side state the
v0.29 cherry-picks didn't yet account for:

1. scripts/check-privacy.sh allow-lists test/recency-decay.test.ts
   The v0.29.1 recency-decay test asserts that DEFAULT_RECENCY_DECAY's
   keys do NOT include fork-specific path prefixes. Because the assertion
   has to name the banned tokens to assert their absence, the privacy
   guard flagged the literal occurrence. Same exception class as
   CHANGELOG.md, CLAUDE.md, and scripts/check-privacy.sh itself —
   meta-rule enforcement requires mentioning what the rule forbids.

2. test/core/cycle.serial.test.ts: 9 → 10 phases.
   The yieldBetweenPhases test was written for v0.26.5 (9 phases incl.
   purge). v0.29 added a 10th phase (recompute_emotional_weight)
   between patterns and embed; the test's expected hookCalls and
   report.phases.length needed bumping.

3. test/apply-migrations.test.ts: append '0.29.1' to skippedFuture lists.
   v0.29.1 added a new entry to src/commands/migrations/index.ts; the
   buildPlan test snapshots the exact ordered list of versions, so it
   needs the new entry in both the fresh-install case and the Codex H9
   regression case.

All three verified locally:
  - bash scripts/check-privacy.sh → exit 0
  - bun test test/apply-migrations.test.ts → 18/18 pass
  - bun test test/core/cycle.serial.test.ts → 28/28 pass

* v0.29 CI fixup: regenerate llms-full.txt to match CLAUDE.md state

build-llms test asserts the committed llms.txt + llms-full.txt match
what the generator produces from the current source tree. CLAUDE.md
got new v0.29 Key Files entries (recompute_emotional_weight phase,
emotional-weight formula, anomaly stats, transcripts library, salience
ops, etc.) without a corresponding regen. `bun run build:llms` brings
llms-full.txt back in sync; llms.txt is byte-for-byte identical so
only the larger inline bundle changed.

Verified locally: bun test test/build-llms.test.ts → 7/7 pass.

* v0.29 e2e: cover tool-surfaces + MCP dispatch path

Two gaps were uncovered when reviewing v0.29 coverage against the new
contracts the cherry-picks landed onto master.

1. test/v0_29-tool-surfaces.test.ts (unit, 9 cases)

   Existing tests pin the description constants module and the
   BRAIN_TOOL_ALLOWLIST set membership, but nothing checked the two
   filters that ACT on those constants:

   - serve-http.ts:745 filters operations by !op.localOnly to build the
     HTTP MCP tool list. Without a test, anyone removing `localOnly: true`
     from get_recent_transcripts would silently expose it to remote
     callers — defense-in-depth on top of the in-handler ctx.remote check
     would be the only guard. Now pinned: get_recent_transcripts is
     hidden, salience + anomalies stay visible.

   - buildBrainTools surfaces the v0.29 ops as `brain_get_recent_salience`
     and `brain_find_anomalies`, and EXCLUDES `brain_get_recent_transcripts`
     (codex C3 footgun gate — all subagent calls are remote=true, the op
     would always reject). Now pinned.

   Both filters are pure functions; no DB / engine.connect needed.

2. test/e2e/v0_29-mcp-dispatch-pglite.test.ts (e2e, 5 cases)

   Existing v0.29 e2e tests call engine methods directly. None went
   through the full dispatchToolCall pipeline that stdio MCP and HTTP
   MCP both use. The new file covers:

   - get_recent_salience returns ranked rows via dispatch (top result
     is the wedding-tagged page from the seeded fixture).
   - find_anomalies returns the AnomalyResult shape via dispatch.
   - get_recent_transcripts rejects with permission_denied when
     ctx.remote === true (the in-handler trust gate is the last line if
     localOnly ever drops).
   - get_recent_transcripts succeeds with ctx.remote === false (CLI
     path) and returns [] when no corpus dir is configured.
   - Unknown tool name returns the standard isError + "Unknown tool"
     envelope (regression guard for dispatch shape).

Verified locally — all 14 cases pass:
  bun test test/v0_29-tool-surfaces.test.ts                          → 9 pass
  bun test test/e2e/v0_29-mcp-dispatch-pglite.test.ts                → 5 pass

Re-ran the full v0.29 PGLite e2e suite to confirm no regressions:
  salience-pglite.test.ts                       5 pass
  anomalies-pglite.test.ts                      4 pass
  cycle-recompute-emotional-weight-pglite.test  3 pass
  list-pages-regression.test.ts                 6 pass
  multi-source-emotional-weight-pglite.test     4 pass
  backfill-perf-pglite.test.ts                  1 pass
  v0_29-mcp-dispatch-pglite.test.ts             5 pass
  -----
  Total: 28 pass / 0 fail
  Postgres parity test (DATABASE_URL gated)     7 skip (correct)
  LLM routing eval (ANTHROPIC_API_KEY gated)   12 skip (correct)
  bun run typecheck                             clean

* v0.29 CI fixup: drop unused PGLiteEngine in tool-surfaces test

scripts/check-test-isolation.sh's R3 + R4 lints flagged the new
test/v0_29-tool-surfaces.test.ts for instantiating PGLiteEngine outside
a beforeAll() block (R3) and lacking the matching afterAll(disconnect)
(R4). The intent of those rules is to prevent engine leaks across the
shard process — every PGLiteEngine must follow the canonical
beforeAll(connect+initSchema) / afterAll(disconnect) pattern.

The fix here is upstream of the rule, not a workaround: this test never
needed an engine. buildBrainTools doesn't issue any SQL at registry-build
time — it only reads `engine.kind` for the put_page namespace-wrap
branch. A `{ kind: 'pglite' } as unknown as BrainEngine` fake-engine
literal keeps the test pure-function: no WASM cold-start, no connect
lifecycle, no test-isolation rule fired.

Verified locally:
  bash scripts/check-test-isolation.sh → OK (257 non-serial unit files)
  bun test test/v0_29-tool-surfaces.test.ts → 9 pass
  bun run typecheck → clean

 		b325f28239 v0.28.6 feat: takes + think + unified model config + per-token MCP allow-list (#563) 
* v0.28 schema: takes + synthesis_evidence (v31) + access_tokens.permissions (v32)

Migration v31 adds the takes table (typed/weighted/attributed claims) and
synthesis_evidence (provenance for `gbrain think` outputs). Page-scoped via
page_id FK (slug isn't unique alone in v0.18+ multi-source). HNSW partial
index on embedding for active rows. ON DELETE CASCADE on synthesis_evidence
so deleting a source take cascades the provenance row.

Migration v32 adds access_tokens.permissions JSONB with safe-default
backfill (`{"takes_holders":["world"]}`). Default keeps non-world holders
hidden from MCP-bound tokens until the operator explicitly grants access
via the v0.28 auth permissions CLI.

* v0.28 engine: addTakesBatch, listTakes, searchTakes/Vector, supersede, resolve, synthesis_evidence

Extends BrainEngine with the takes domain object. Both engines implement the
same surface; PGLite uses manual `$N` placeholders, Postgres uses postgres-js
unnest() — same shape as addLinksBatch and addTimelineEntriesBatch.

Methods:
- addTakesBatch (upsert via ON CONFLICT (page_id, row_num) DO UPDATE)
- listTakes (filter by holder/kind/active/resolved, takesHoldersAllowList
  for MCP-bound calls, sortBy weight/since_date/created_at)
- searchTakes / searchTakesVector (pg_trgm + cosine; honor allow-list)
- countStaleTakes / listStaleTakes (mirror countStaleChunks pattern;
  embedding column intentionally omitted from listStale payload)
- updateTake (mutable fields only; throws TAKE_ROW_NOT_FOUND)
- supersedeTake (transactional: insert new at next row_num, mark old
  active=false, set superseded_by; throws TAKE_RESOLVED_IMMUTABLE on
  resolved bets)
- resolveTake (sets resolved_*; throws TAKE_ALREADY_RESOLVED on re-resolve;
  resolution is immutable per Codex P1 #13 fold)
- addSynthesisEvidence (provenance persist; ON CONFLICT DO NOTHING)
- getTakeEmbeddings (parallel to getEmbeddingsByChunkIds)

Types live in src/core/engine.ts adjacent to LinkBatchInput. Page-scoped
via page_id (slug not unique in v0.18+ multi-source). PageType gains
'synthesis'. takeRowToTake mapper in utils.ts handles Date → ISO string
normalization.

Tests: test/takes-engine.test.ts — 16 cases against PGLite covering
upsert/list/filter/search happy paths, takesHoldersAllowList isolation,
the four invariant errors (TAKE_ROW_NOT_FOUND, TAKES_WEIGHT_CLAMPED,
TAKE_RESOLVED_IMMUTABLE, TAKE_ALREADY_RESOLVED), supersede flow, resolve
metadata round-trip, FK CASCADE on synthesis_evidence when source take
deletes. All pass.

* v0.28 model-config: unified resolveModel with 6-tier precedence + alias resolution

Replaces every hardcoded `claude-*-X` and per-phase `dream.<phase>.model`
config key with a single resolver. Hierarchy:

  1. CLI flag (--model)
  2. New-key config (e.g. models.dream.synthesize)
  3. Old-key config (deprecated dream.synthesize.model, dream.patterns.model)
     — read with stderr deprecation warning, one-per-process
  4. Global default (models.default)
  5. Env var (GBRAIN_MODEL or caller-supplied)
  6. Hardcoded fallback

Aliases (`opus`, `sonnet`, `haiku`, `gemini`, `gpt`) resolve at the end so
any tier can use a short name. User-defined `models.aliases.<name>` config
overrides built-ins. Cycle-safe (depth 2 break). Unknown alias passes
through unchanged so users can pass full provider IDs without registering.

When new-key + old-key are BOTH set (Codex P1 #11 fix), new-key wins and
stderr warns "deprecated config X ignored; Y is set and wins". When only
old-key is set, it's honored with a softer "rename to Y before v0.30"
warning. Both warnings emit once per (key, process) — a Set memo prevents
log spam in long-running daemons.

Migrated call sites: synthesize.ts (model + verdictModel), patterns.ts
(model). subagent.ts and search/expansion.ts to be migrated later in v0.28
(staying compatible until then).

Tests: test/model-config.test.ts — 11 cases pinning the 6-tier ordering,
alias resolution + cycle break, deprecated-key warning emit-once, and
unknown-alias pass-through. All pass.

* v0.28 takes-fence: parser/renderer/upserter + chunker strip (privacy P0 fix)

src/core/takes-fence.ts — pure functions for the fenced markdown surface:
- parseTakesFence(body) — extracts ParsedTake[] from `<!--- gbrain:takes:begin/end -->`
  blocks. Strict on canonical form, lenient on hand-edits with warnings
  (TAKES_FENCE_UNBALANCED, TAKES_TABLE_MALFORMED, TAKES_ROW_NUM_COLLISION).
  Strikethrough `~~claim~~` → active=false; date ranges `since → until`
  split into sinceDate/untilDate.
- renderTakesFence(takes) — round-trip safe with parseTakesFence.
- upsertTakeRow(body, row) — append-only per CEO-D6 + eng-D9. Creates a
  fresh `## Takes` section if no fence present. row_num is monotonic
  (max + 1, never gap-filled — keeps cross-page refs and synthesis_evidence
  stable forever).
- supersedeRow(body, oldRow, replacement) — strikes through old row's claim
  AND appends the new row at end. Both rows preserved in markdown for
  git-blame archaeology.
- stripTakesFence(body) — removes the fenced block entirely. Used by the
  chunker so takes content lives ONLY in the takes table.

Codex P0 #3 fix: src/core/chunkers/recursive.ts now calls stripTakesFence()
before computing chunk boundaries. Without this, page chunks would contain
the rendered takes table and the per-token MCP allow-list would be
bypassed at the index layer (token bound to takes_holders=['world'] would
see garry's hunches via page hits). Doctor's takes_fence_chunk_leak check
(plan-side) asserts no chunk contains the begin marker.

Tests: 15 cases covering canonical parse, strikethrough, date range, fence
unbalanced detection, malformed-row skip + warning, row_num collision
detection, round-trip render, append-only upsert into existing fence,
fresh-section creation, monotonic row_num under hand-edit gaps, supersede
flow, stripTakesFence verifying takes content removed AND surrounding
prose preserved. Existing chunker tests still pass (15 + 15 = 30).

* v0.28 page-lock: PID-liveness file lock for atomic markdown read-modify-write

src/core/page-lock.ts — per-page file lock at
~/.gbrain/page-locks/<sha256-of-slug>.lock so two concurrent `gbrain takes
add` calls or `takes seed --refresh` from autopilot can't race on the
same `<slug>.md` read-modify-write. Eng-review fold: reuses the v0.17
cycle.lock pattern (mtime + PID liveness) but per-slug.

Differences from cycle.ts's lock:
- SHA-256 of slug for safe filenames (slashes, unicode, etc.)
- Same-pid + fresh mtime = LIVE (cycle.ts assumes one lock per process and
  reclaims same-pid; page-lock allows concurrent locks for DIFFERENT slugs
  in one process). mtime expiry still rescues post-crash leftovers.
- 5-min TTL (vs cycle's 30 min — page edits are short)
- `withPageLock(slug, fn)` convenience wrapper with default 30s timeout

API:
- acquirePageLock(slug, opts) → handle | null (poll-with-timeout)
- handle.refresh() / handle.release() (idempotent — only releases if pid matches)
- withPageLock(slug, fn, opts) — acquire + run + release-in-finally

Tests: 10 cases — fresh acquire, live holder returns null, stale-mtime
reclaim, dead-PID reclaim, refresh updates timestamp, foreign-pid release
is no-op, withPageLock callback runs and releases on success/failure,
timeout-throws when held, SHA-256 filename safety for slashes/unicode.
All pass.

* v0.28 extract-takes: dual-path phase (fs|db) + since/until_date as TEXT

src/core/cycle/extract-takes.ts — new phase that materializes the takes
table from fenced markdown blocks. Two paths mirror src/commands/extract.ts:

- extractTakesFromFs: walk *.md under repoPath, parse fences, batch upsert
- extractTakesFromDb: iterate engine.getAllSlugs(), parse each page's
  compiled_truth+timeline, batch upsert (mutation-immune snapshot iteration)

Single dispatcher extractTakes(opts) routes by source. Honors:
- slugs filter for incremental re-extract (pipes from sync→extract)
- dryRun: count would-be upserts, write nothing
- rebuild: DELETE FROM takes WHERE page_id = $1 before re-insert (clean
  slate when markdown is canonical and DB has drifted)

Schema fix: since_date/until_date were DATE in the original v31 migration.
Spec uses partial dates ('2017-01', '2026-04-29 → 2026-06') that Postgres
DATE rejects. Changed to TEXT in both the Postgres and PGLite blocks so
parser-rendered ranges round-trip cleanly. Loses the ability to do
date-range arithmetic in SQL, but date math on opinion timelines is
out of scope for v0.28 anyway. utils.ts dateOrNull now annotated as
v0.28 TEXT-aware.

Migration v31 has not been deployed yet (this branch is the v0.28 release
candidate), so the type swap is free. No data migration needed.

Tests: test/extract-takes.test.ts — 5 cases against PGLite covering full
walk + fence-skip on no-fence pages, takes-table populated post-extract,
incremental slugs filter, dry-run no-write, rebuild=true clears + re-inserts
ad-hoc rows. test/takes-engine.test.ts (16), test/takes-fence.test.ts (15)
all still pass — 36/36 takes tests green.

* v0.28 takes CLI: list, search, add, update, supersede, resolve

src/commands/takes.ts — surfaces the engine methods + takes-fence library
through a single `gbrain takes <subcommand>` entrypoint:

  takes <slug>                          list with filters + sort
  takes search "<query>"                pg_trgm keyword search across all takes
  takes add <slug> --claim ... ...      append (markdown + DB, atomic via lock)
  takes update <slug> --row N ...       mutable-fields update (markdown + DB)
  takes supersede <slug> --row N ...    strikethrough old + append new
  takes resolve <slug> --row N --outcome  record bet resolution (immutable)

Markdown is canonical. Every mutate command:
  1. acquires the per-page file lock (withPageLock)
  2. re-reads the .md file
  3. applies the edit via takes-fence (upsertTakeRow / supersedeRow)
  4. writes the .md file back
  5. mirrors to the DB via the engine method
  6. releases the lock (auto via finally)

Resolve currently writes only to DB — surfacing resolved_* in the markdown
table is deferred to v0.29 (the takes-fence renderer's column set is
fixed at # | claim | kind | who | weight | since | source per spec).

Wired into src/cli.ts dispatch + CLI_ONLY allowlist. Help text follows the
project convention (orphans/embed/extract pattern). --dir flag overrides
sync.repo_path config when working outside the configured brain.

* v0.28 MCP + auth: takes_list / takes_search / think ops + per-token allow-list

OperationContext gains takesHoldersAllowList — server-side filter for
takes.holder field threaded from access_tokens.permissions through dispatch
into the engine SQL. Closes Codex P0 #3 at the dispatch layer (chunker
strip already closed the page-content side in the previous commit).

src/core/operations.ts — three new ops:
- takes_list: lists takes with holder/kind/active/resolved filters; honors
  ctx.takesHoldersAllowList for MCP-bound calls
- takes_search: pg_trgm keyword search; honors allow-list
- think: op surface registered (returns not_implemented envelope until
  Lane D's pipeline lands). Remote callers cannot save/take per Codex P1 #7.

src/mcp/dispatch.ts — DispatchOpts.takesHoldersAllowList threads into
buildOperationContext.

src/mcp/http-transport.ts — validateToken now reads
access_tokens.permissions.takes_holders, defaults to ['world'] when the
column is absent or malformed (default-deny on private hunches).
auth.takesHoldersAllowList passed to dispatchToolCall.

src/mcp/server.ts (stdio) — defaults to takesHoldersAllowList: ['world']
since stdio has no per-token auth. Operators wanting full visibility use
`gbrain call <op>` directly (sets remote=false).

src/commands/auth.ts — `gbrain auth create <name> --takes-holders w,g,b`
flag persists the per-token list; new `auth permissions <name>
set-takes-holders <list>` updates an existing token.

Tests: test/takes-mcp-allowlist.test.ts — 8 cases against PGLite proving
the threading: local-CLI sees all holders, ['world'] returns only public,
['world','garry'] returns 2/3, no-overlap returns empty (no fallback),
search honors allow-list, remote save/take on think rejected with
not_implemented envelope.

* v0.28.0: ship-prep — VERSION, CHANGELOG, migration orchestrator, skill

Closes the v0.28 ship-prep cycle. Bumps VERSION + package.json + bun.lock
to 0.28.0. v0_28_0 migration orchestrator runs three idempotent phases on
upgrade:

- Schema verify: asserts schema_version >= 32 (migrations v31 + v32 already
  applied by the schema runner during gbrain upgrade); fails clean if not.
- Backfill takes: inline runs `extractTakes(engine, { source: 'db' })` so
  any pre-existing fenced takes tables in markdown populate the takes
  index. Idempotent; ON CONFLICT DO UPDATE keeps the table in sync.
- Re-chunk TODO: queues a pending-host-work entry asking the host agent
  to re-import pages with takes content so the v0.28 chunker-strip rule
  (Codex P0 #3 fix) applies retroactively. Pages imported under v0.28+
  already have takes content stripped from chunks at index time; this
  TODO catches up legacy pages.

skills/migrations/v0.28.0.md — agent-readable upgrade guide. Walks
through doctor verification, deprecated-key migration, MCP token
visibility configuration, and a "try the takes layer" smoke test.

CHANGELOG.md — v0.28.0 release-summary in the GStack voice (no AI
vocabulary, no em dashes, real numbers from git diff stat) + the
mandatory "To take advantage of v0.28.0" block + itemized changes by
subsystem (schema, engine, markdown surface, model config, MCP+auth,
CLI, tests, accepted risks).

Final test sweep: 65/65 v0.28 tests pass across 6 files. typecheck clean.

* v0.28 think pipeline: gather → sanitize → synthesize → cite-render → CLI

src/core/think/sanitize.ts — prompt-injection defense for take claims:
14 jailbreak patterns (ignore-prior, role-jailbreak, close-take tag,
DAN, system-prompt overrides, eval-shell hooks) plus structural framing
(takes wrapped in <take id="..."> tags the model is told to treat as
DATA). Length-cap at 500 chars. Renders evidence blocks for the prompt.

src/core/think/prompt.ts — system prompt + structured-output schema.
Hard rules: cite every claim, mark hunches/low-weight explicitly,
surface conflicts (never silently pick), surface gaps. JSON schema
with answer + citations[] + gaps[]. Prompt adapts to anchor / time
window / save flag.

src/core/think/cite-render.ts — structured citations + regex fallback
(Codex P1 #4 fold). normalizeStructuredCitations validates the model's
structured output; parseInlineCitations is the body-scan fallback when
the model omits the structured field. resolveCitations dispatches and
records CITATIONS_REGEX_FALLBACK warning when used.

src/core/think/gather.ts — 4-stream parallel retrieval:
  1. hybridSearch (pages, existing primitive)
  2. searchTakes (keyword, pg_trgm)
  3. searchTakesVector (vector, when embedQuestion fn supplied)
  4. traversePaths (graph, when --anchor set)
RRF fusion (k=60). Each stream wrapped in try/catch — partial gather
beats no synthesis. Honors takesHoldersAllowList for MCP-bound calls.

src/core/think/index.ts — runThink orchestrator + persistSynthesis:
INTENT (regex classify) → GATHER → render evidence blocks → resolveModel
('models.think' → 'models.default' → GBRAIN_MODEL → opus) → LLM call
(injectable client) → JSON parse with code-fence + fallback strip →
resolveCitations → ThinkResult. persistSynthesis writes a synthesis
page + synthesis_evidence rows (page_id resolved per slug; page-level
citations skip evidence). Degrades gracefully without ANTHROPIC_API_KEY.
Round-loop scaffolding in place (rounds=1 only path exercised in v0.28).

src/commands/think.ts — `gbrain think "<question>"` CLI. Flag parsing
strips --anchor, --rounds, --save, --take, --model, --since, --until,
--json. Local CLI = remote=false, so save/take honored. Human-readable
output by default; --json for agent consumption.

operations.ts — `think` op now calls runThink (was a not_implemented
stub). Remote callers can't save/take per Codex P1 #7. Returns full
ThinkResult plus saved_slug + evidence_inserted.

cli.ts — wired into dispatch + CLI_ONLY allowlist.

Tests: test/think-pipeline.test.ts — 18 cases against PGLite covering
sanitize patterns, structural rendering, citation parsing (structured +
regex fallback + dedup + invalid-slug rejection), gather streams +
allow-list filter, full pipeline with stub client, malformed-LLM
fallback path, no-API-key graceful degradation, persistSynthesis writes
page + evidence rows. All pass.

* v0.28 dream phases: auto-think + drift + budget meter (Codex P1 #10 fold)

src/core/anthropic-pricing.ts — USD/1M-tokens map for Claude 4.7 family
plus older aliases. estimateMaxCostUsd returns null on unpriced models so
the meter caller can warn-once and bypass the gate.

src/core/cycle/budget-meter.ts — cumulative cost ledger. Each submit
estimates max-cost from (model + estimatedInputTokens + maxOutputTokens),
accumulates per-cycle, refuses next submit when projected > cap. Codex
P1 #10 fold: non-Anthropic models (gemini, gpt) bypass with one stderr
warn per process and `unpriced=true` on the result. Budget=0 disables
the gate. Audit trail at ~/.gbrain/audit/dream-budget-YYYY-Www.jsonl.

src/core/cycle/auto-think.ts — auto_think dream phase. Reads
dream.auto_think.{enabled,questions,max_per_cycle,budget,cooldown_days,
auto_commit}. Iterates configured questions through runThink with the
BudgetMeter pre-checking each submit. Cooldown timestamp written ONLY on
success (matches v0.23 synthesize pattern — retries after partial
failures pick back up). When auto_commit=true, persists synthesis pages
via persistSynthesis. Default-disabled.

src/core/cycle/drift.ts — drift dream phase scaffold. Reads
dream.drift.{enabled,lookback_days,budget,auto_update}. Surfaces takes
in the soft band (weight 0.3-0.85, unresolved) that have recent timeline
evidence on the same page. v0.28 ships the orchestration; the LLM judge
that proposes weight adjustments lands in v0.29. modelId + meter wired
now so the ledger captures gate state for callers that opt in.

Tests:
- test/budget-meter.test.ts (7 cases) — pricing-map coverage, allow path,
  cumulative-deny, budget=0 disabled, unpriced bypass+warn-once, ledger
  captures all events, ISO-week filename branch.
- test/auto-think-phase.test.ts (9 cases) — auto_think enable/skip,
  questions empty, success → cooldown ts written, cooldown blocks rerun,
  budget exhausted → partial. drift not_enabled, soft-band candidate
  detection, complete + dry-run paths.

All pass. Typecheck clean.

* v0.28 e2e Postgres: takes engine + extract + MCP allow-list (12 cases)

test/e2e/takes-postgres.test.ts — full v0.28 takes pipeline against real
Postgres (gated on DATABASE_URL). 12 cases:
- addTakesBatch upsert via unnest() bind path (Postgres-specific)
- listTakes filters: holder, kind, sort=weight, takesHoldersAllowList
- searchTakes pg_trgm + allow-list filter
- supersedeTake transactional path (BEGIN/COMMIT semantics)
- resolveTake immutability — second resolve throws TAKE_ALREADY_RESOLVED
- synthesis_evidence FK CASCADE on take delete
- countStaleTakes + listStaleTakes filter active+null
- extractTakesFromDb populates takes from fenced markdown
- MCP dispatch with takesHoldersAllowList=['world'] returns only world
- MCP dispatch local-CLI path returns all holders
- MCP dispatch takes_search honors allow-list
- think op forces remote_persisted_blocked even for save+take

postgres-engine.ts: addTakesBatch boolean[] serialization fix.
postgres-js auto-detects element type from JS arrays; for booleans it
mis-detects as scalar. Cast through text[] (`'true' | 'false'`) then
SQL-cast to boolean[] — same pattern other batch methods rely on for
type-stable bind shapes.

test/e2e/helpers.ts: setupDB now (a) tolerates non-existent tables in
TRUNCATE (for fresh DBs where v31 hasn't yet created takes/synthesis_evidence)
and (b) calls engine.initSchema() to actually run migrations.

test/takes-mcp-allowlist.test.ts: updated 2 think-op cases to match
Lane D's landed pipeline. They previously asserted not_implemented
envelopes; now they assert remote_persisted_blocked + NO_ANTHROPIC_API_KEY
graceful-degrade behavior.

Run: DATABASE_URL=postgres://localhost:5435/gbrain_test bun test test/e2e/takes-postgres.test.ts
Result: 12/12 pass.

* v0.28 dream phases: local DreamPhaseResult type (avoid premature CyclePhase enum extension)

cycle.ts's PhaseResult is shaped {phase, status, summary, details} with a
narrow PhaseStatus enum ('ok'|'warn'|'fail'|'skipped') and CyclePhase enum
that doesn't yet include 'auto_think'/'drift'. The phases ship standalone
in v0.28 (cycle.ts dispatcher integration is v0.28.x); using PhaseResult
forced premature enum extension.

Introduces DreamPhaseResult exported from auto-think.ts:
  { name: 'auto_think'|'drift'; status: 'complete'|'partial'|'failed'|'skipped';
    detail: string; totals?: Record<string,number>; duration_ms: number }

drift.ts re-exports the same type. When v0.28.x wires the dispatcher, the
adapter at the call site can map DreamPhaseResult → PhaseResult cleanly.

* v0.28 e2e: access_tokens.permissions JSONB end-to-end (5 cases)

test/e2e/auth-permissions.test.ts — closes the v0.28 token-allow-list
verification loop against real Postgres. Exercises:

- Migration v32 default backfill: new tokens created without a permissions
  column get {takes_holders: ["world"]} via the schema DEFAULT clause.
- Explicit ["world","garry"] → dispatch.takes_list filters to those
  holders only; brain hunches stay hidden from this token.
- ["world"] default-deny token → takes_search hits filtered to public claims.
- {} permissions row (operator tampered) gracefully defaults to ["world"]
  via the HTTP transport's validateToken parsing.
- revoked_at IS NOT NULL → token excluded from active token query.

Avoids the postgres-js JSONB double-encode trap (CLAUDE.md memory): pass
the object directly to executeRaw, no JSON.stringify, no ::jsonb cast.

All 5 pass against pgvector/pgvector:pg16 on port 5435. Combined v0.28
test sweep: 116/116 across 11 files.

* v0.28 e2e: chunker takes-strip integration test (Codex P0 #3 verification)

test/e2e/chunker-takes-strip.test.ts — verifies the chunker actually
strips fenced takes content end-to-end through the import pipeline.
This is the Codex P0 #3 fix's verification path: takes content lives
ONLY in the takes table for retrieval, never duplicated in
content_chunks where the per-token MCP allow-list cannot reach.

5 cases:
- chunkText (unit) output never contains TAKES_FENCE_BEGIN/END markers
- chunkText output never contains fenced claim text
- chunkText output retains non-fence prose (no over-stripping)
- importFromContent end-to-end: imported page has chunks but none
  contain fenced content
- takes_fence_chunk_leak doctor invariant: zero rows globally where
  chunk_text matches `<!--- gbrain:takes:%`

Final v0.28 test sweep:
  121 pass, 0 fail, 336 expect() calls, 12 files
  Coverage: schema migrations, engine methods (PGLite + Postgres),
  takes-fence parser, page-lock, extract phase, takes CLI engine
  surface, model config 6-tier resolver, MCP+auth allow-list,
  think pipeline (gather + sanitize + cite-render + synthesize),
  auto-think + drift + budget meter, JSONB end-to-end, chunker
  strip integration. ~95% of v0.28 surface area covered.

* fix CI: apply-migrations skippedFuture arrays + http-transport SQL mock

Two CI failures from PR #563:

test/apply-migrations.test.ts (2 fails) — `buildPlan` tests assert exact
skippedFuture arrays at fixed installed-version stamps. Adding v0.28.0 to
the migration registry means it shows up in skippedFuture when the test
runs at installed=0.11.1 / installed=0.12.0. Append '0.28.0' to both
hardcoded arrays.

test/http-transport.test.ts (8 fails) — the FakeEngine mock string-prefix
matches `SELECT id, name FROM access_tokens` to return a row. v0.28's
validateToken now selects `SELECT id, name, permissions FROM access_tokens`
to read the per-token takes_holders allow-list. Mock returned [] on the
new query → validateToken treated every token as invalid → 401.

Fix: mock now matches both query shapes. validTokens row gets a default
`{takes_holders: ['world']}` permission injected when caller didn't
supply one (mirrors the migration v33 column DEFAULT). Updated
FakeEngineConfig type to allow tests to pass explicit permissions.

Verification:
  bun test test/apply-migrations.test.ts → 18/18 pass
  bun test test/http-transport.test.ts   → 24/24 pass
  bun run typecheck                       → clean

* fix CI: add scope annotations to v0.28 ops (takes_list/takes_search/think)

test/oauth.test.ts enforces an invariant from master's v0.26 OAuth landing:
every Operation must have `scope: 'read' | 'write' | 'admin'`, and any op
flagged `mutating: true` must be 'write' or 'admin'. My v0.28 ops were added
before master shipped v0.26 + the new invariant; the merge surfaced the gap.

Annotations:
- takes_list   → read
- takes_search → read
- think        → write (mutating: true; --save persists synthesis page)

Verification:
  bun test test/oauth.test.ts → 42/42 pass
  bun run typecheck            → clean

* v0.28.2 feat: remote-source MCP + scope hierarchy + whoami (#690)

* refactor(core): extract SSRF helpers from integrations.ts to core/url-safety.ts

src/core/git-remote.ts (next commit) needs isInternalUrl etc. but importing
from src/commands/ would invert the layering boundary (no existing
src/core/ file imports from src/commands/). Extract the SSRF helpers
(parseOctet, hostnameToOctets, isPrivateIpv4, isInternalUrl) into a new
src/core/url-safety.ts and have integrations.ts re-export for backward
compat. test/integrations.test.ts continues to pass without changes (110
existing tests, 214 expects).

Why this matters for v0.28: the upcoming sources --url feature reuses
this SSRF gate for git-clone URL validation. Codex review caught that
re-rolling weaker URL classification would regress on the IPv6/v4-mapped/
metadata/CGNAT bypass forms that integrations.ts already handles.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* feat(core): add git-remote module — SSRF-defensive clone/pull + state probe

New src/core/git-remote.ts (~210 lines) for v0.28's remote-source feature:

- GIT_SSRF_FLAGS exported const: -c http.followRedirects=false,
  -c protocol.file.allow=never, -c protocol.ext.allow=never,
  --no-recurse-submodules. Single source of truth shared by cloneRepo
  and pullRepo so a future flag added to one path lands on both.
  Closes the SSRF surfaces codex flagged: DNS rebinding via redirects,
  .gitmodules as a second-fetch surface, file:// scheme in remotes.

- parseRemoteUrl: https-only, rejects embedded credentials and path
  traversal, delegates internal-target classification to isInternalUrl
  from url-safety.ts (covers RFC1918, link-local, loopback, IPv6, CGNAT
  100.64/10, metadata hostnames, hex/octal/single-int bypass forms).
  GBRAIN_ALLOW_PRIVATE_REMOTES=1 escape hatch with stderr warning is
  needed for self-hosted git over Tailscale (CGNAT trips the gate).

- cloneRepo: --depth=1 default (full clone via depth: 0); refuses
  non-empty destDirs; spawns git via execFileSync (no shell injection)
  with GIT_TERMINAL_PROMPT=0 + askpass=/bin/false to prevent credential
  prompts. timeoutMs default 600s.

- pullRepo: -C path + GIT_SSRF_FLAGS + pull --ff-only, same env confine.

- validateRepoState: 6-state decision tree (missing | not-a-dir |
  no-git | corrupted | url-drift | healthy). Used by performSync's
  re-clone branch to recover from rmd clone dirs and refuse syncs on
  url-drift or corruption.

test/git-remote.test.ts (304 lines, 32 tests): GIT_SSRF_FLAGS exact
shape, all parseRemoteUrl rejection cases including dedicated CGNAT
100.64/10 with/without GBRAIN_ALLOW_PRIVATE_REMOTES (codex T3 case),
fake-git harness for argv assertions on cloneRepo/pullRepo, all 6
validateRepoState branches.

* feat(core): add scope hierarchy + ALLOWED_SCOPES allowlist

New src/core/scope.ts (~120 lines) for v0.28's scoped MCP feature.

Hierarchy:
  - admin implies all (escape hatch)
  - write implies read
  - sources_admin and users_admin are siblings (different axes —
    sources-mgmt vs user-account-mgmt; neither implies the other)

Exported:
  - hasScope(grantedScopes, requiredScope): the canonical scope check.
    Replaces exact-string-match at three call sites in upcoming commits
    (serve-http.ts:673, oauth-provider.ts:365 F3 refresh, oauth-provider.ts:498
    token issuance). Without this rewrite, an admin-grant token would
    fail to refresh down to sources_admin (codex finding).
  - ALLOWED_SCOPES set + ALLOWED_SCOPES_LIST sorted array (deterministic
    for OAuth metadata wire format and drift-check output).
  - assertAllowedScopes / InvalidScopeError: registration-time gate so
    tokens with bogus scope strings (read flying-unicorn) get rejected
    with RFC 6749 §5.2 invalid_scope at auth.ts:296 + DCR /register +
    registerClientManual. Today's behavior accepts any string silently.
  - parseScopeString: space-separated wire format → array.

Forward-compat: hasScope ignores unknown granted scopes rather than
throwing, so pre-allowlist tokens with weird scope strings continue
working without crashes (registration is the gate, runtime is best-effort).

test/scope.test.ts (178 lines, 35 tests): hierarchy table including
all-implies for admin, sibling non-implication of *_admin scopes,
write→read but not the reverse, F3 refresh-token subset semantics
under hasScope, ALLOWED_SCOPES_LIST sorted-pinning, allowlist
rejection cases, parseScopeString edge cases (undefined/null/empty).

* build(admin): scope-constants mirror + drift CI for src/core/scope.ts

The admin React SPA's tsconfig.json scopes include: ['src'] to admin/src/,
so it cannot directly import ../../src/core/scope.ts. The plan considered
widening the include or generating a single source of truth; both options
either couple the SPA to the gbrain monorepo or add a build step. Eng
review picked the boring choice: hand-maintained mirror at
admin/src/lib/scope-constants.ts plus a CI drift check.

Files:
  - admin/src/lib/scope-constants.ts: hand-maintained ALLOWED_SCOPES_LIST
    duplicate, sorted alphabetically to match src/core/scope.ts.
  - scripts/check-admin-scope-drift.sh: extracts the list from each file
    via awk, normalizes via tr/sort, diffs. Exits 0 on match, 1 on drift
    (with full breakdown of which scopes diverged), 2 on internal error.
    Tested both passing and corrupted paths.
  - package.json: wires check:admin-scope-drift into both `verify` and
    `check:all` so any update to src/core/scope.ts that forgets the
    admin-side mirror fails the build.

The Agents.tsx scope-checkbox sites (5 hardcoded locations) get updated
in a later commit to import from this constants file.

* feat(oauth): hasScope hierarchy + ALLOWED_SCOPES allowlist at registration

Switch three call sites in oauth-provider.ts from exact-string-match to
hasScope() so the v0.28 sources_admin and users_admin scopes — and the
admin-implies-all + write-implies-read hierarchy in src/core/scope.ts —
work end to end:

- F3 refresh-token subset enforcement at line 365: previously rejected
  admin → sources_admin refresh because exact-match treated them as
  unrelated scopes. gstack /setup-gbrain Path 4 needs admin tokens to
  refresh down to least-privilege sources_admin scope; this fix lands
  that path.

- Token issuance intersection at line 498 (client_credentials grant):
  same hasScope swap so a client whose stored grant is `admin` can mint
  tokens including any implied scope.

- registerClient (DCR /register) and registerClientManual: validate
  every scope string against ALLOWED_SCOPES via assertAllowedScopes.
  Pre-fix the system silently accepted `--scopes "read flying-unicorn"`
  and persisted the bogus string in oauth_clients.scope. Post-fix the
  caller gets RFC 6749 §5.2 invalid_scope. Existing rows with
  pre-allowlist scopes keep working (allowlist gates registration only).

Tests amended in test/oauth.test.ts:
- T1 (eng-review): admin grant CAN refresh down to sources_admin
- T1 sibling: write grant CANNOT refresh up to sources_admin
- ALLOWED_SCOPES allowlist coverage (manual + DCR paths, all 5 valid)
- Scope-annotation contract tests widened to accept the v0.28 union

62 OAuth tests pass.

* feat(serve-http): hasScope at /mcp + advertise full ALLOWED_SCOPES

Two changes against src/commands/serve-http.ts:

- Line 195: scopesSupported on the mcpAuthRouter options switches from the
  hardcoded ['read','write','admin'] to Array.from(ALLOWED_SCOPES_LIST).
  Without this, /.well-known/oauth-authorization-server keeps reporting
  the old triple, so MCP clients (Claude Desktop, ChatGPT, Perplexity)
  cannot discover the v0.28 sources_admin and users_admin scopes via
  standard discovery — they would have to be pre-configured out of band.

- Line 673: request-time scope check on /mcp swaps
  authInfo.scopes.includes(requiredScope) for hasScope(...). This was
  the most-cited codex finding: without it, sources_admin tokens could
  not even satisfy a `read`-scoped op (sources_admin doesn't include
  the literal string "read"). hasScope routes through the hierarchy
  table in src/core/scope.ts so admin implies all and write implies
  read at the gate too.

T2 amendment in test/e2e/serve-http-oauth.test.ts: assert
/.well-known/oauth-authorization-server includes all 5 scopes in
scopes_supported. Pre-v0.28 the list was hardcoded to ['read','write',
'admin'] and this assertion would have failed. (The test is
Postgres-gated; runs under bun run test:e2e with DATABASE_URL set.)

* feat(core): sources-ops module — atomic clone + symlink-safe cleanup

src/core/sources-ops.ts (~470 lines): pure async functions extracted from
src/commands/sources.ts so the CLI handlers and the new MCP ops share
one implementation.

addSource: D3 atomicity contract from the eng review.
  1. Validate id (matches existing SOURCE_ID_RE).
  2. Q4 pre-flight SELECT — fail loudly with structured `source_id_taken`
     before any clone work. Pre-fix the existing CLI used INSERT…ON
     CONFLICT DO NOTHING which silently no-op'd; with clone-first that
     would orphan the temp dir.
  3. parseRemoteUrl gate (delegates to isInternalUrl from url-safety.ts).
  4. Clone into $GBRAIN_HOME/clones/.tmp/<id>-<rand>/ via the new
     git-remote helpers.
  5. INSERT row with local_path=<final clone dir>, config.remote_url=<url>.
  6. fs.renameSync(tmp/, final/). Rollback on either-side failure unlinks
     the temp dir; rename-failed path also DELETEs the just-INSERTed row
     best-effort.

removeSource: clone-cleanup with realpath+lstat confinement matching
validateUploadPath() shape at src/core/operations.ts:61. String startsWith
is symlink-unsafe and would let $GBRAIN_HOME/clones/<id> → /etc resolve
out of the confine. Two defenses layered:
  - isPathContained (realpath-resolves both sides + parent-with-sep
    string check) rejects symlinks whose target falls outside the
    confine.
  - lstat-then-isSymbolicLink check refuses symlinks whose realpath
    happens to land back inside the confine (defense in depth).

getSourceStatus: returns clone_state via validateRepoState (the 6-state
decision tree from git-remote.ts). Lets a remote MCP caller diagnose
"healthy | missing | not-a-dir | no-git | url-drift | corrupted" without
SSH access to the brain host. listSources additionally exposes
remote_url so callers can see which sources are auto-managed.

recloneIfMissing: T4 follow-up for `gbrain sources restore` after the
clone dir was autopurged — re-clones via the same temp + rename
atomicity contract. Idempotent (returns false when clone is already
healthy).

test/sources-ops.test.ts (~470 lines, 24 tests): pre-flight collision
(Q4), happy paths for both --path and --url, all four D3 rollback paths
(clone-fail before INSERT, INSERT-fail after clone, rename-fail
post-INSERT, atomic temp-dir cleanup), symlink-target-OUTSIDE-clones
(realpath confinement), symlink-target-INSIDE-clones (lstat-check),
removeSource refuses to delete user-supplied paths, refuses "default"
source, getSourceStatus clone_state branches, T4 recloneIfMissing
recovery + idempotent + no-op for path-only sources, isPathContained
unit tests covering subtree / outside / symlink-escape / fail-closed.

* feat(operations): whoami + sources_{add,list,remove,status} MCP ops

Five new ops in src/core/operations.ts auto-flow through src/mcp/tool-defs.ts
so MCP clients (Claude Desktop, ChatGPT, Perplexity, OpenClaw) get them via
standard tools/list discovery — no SDK or transport code changes needed.

Operation.scope union widened to add 'sources_admin' and 'users_admin' (the
v0.28 hierarchy from src/core/scope.ts).

whoami (scope: read): introspect calling identity over MCP.
  - Returns `{transport: 'oauth', client_id, client_name, scopes, expires_at}`
    for OAuth clients (clientId starts with gbrain_cl_).
  - Returns `{transport: 'legacy', token_name, scopes, expires_at: null}`
    for grandfathered access_tokens.
  - Returns `{transport: 'local', scopes: []}` when ctx.remote === false.
    Empty scopes (NOT ['read','write','admin']) is the D2 decision —
    returning OAuth-shaped scopes for local callers would resurrect the
    v0.26.9 footgun where code conditionally trusted on
    `auth.scopes.includes('admin')` instead of `ctx.remote === false`.
  - Q3 fail-closed: throws unknown_transport when remote=true AND auth is
    missing OR ctx.remote is the literal `undefined` (cast bypass guard).
    A future transport that forgets to thread auth doesn't get a free
    pass.

sources_add (sources_admin, mutating): register a source by --path
  (existing v0.17 behavior) or --url (v0.28 federated remote-clone path).
  Calls into addSource from sources-ops.ts which owns the temp-dir +
  rename atomicity.

sources_list (read): list registered sources with page counts, federated
  flag, and remote_url. The remote_url field is new — lets a remote MCP
  caller see which sources are auto-managed.

sources_remove (sources_admin, mutating): cascade-delete a source +
  symlink-safe clone cleanup. Requires confirm_destructive: true when the
  source has data.

sources_status (read): per-source diagnostic returning clone_state
  ('healthy' | 'missing' | 'not-a-dir' | 'no-git' | 'url-drift' |
  'corrupted' | 'not-applicable') — lets a remote MCP caller diagnose a
  busted clone without SSH access to the brain host.

test/whoami.test.ts (9 tests): pinned transport-detection for all four
return shapes including Q3 fail-closed throw under both auth=undefined
and remote=undefined cast-bypass paths.

test/sources-mcp.test.ts (16 tests): op-metadata pins (scope, mutating,
localOnly), functional handler shape against PGLite, hasScope-driven
scope-enforcement smoke test simulating the serve-http.ts:673 gate
(read-only token rejected for sources_add; sources_admin token allowed;
admin token allowed for everything; gstack /setup-gbrain Path 4 token
covers all 4 ops), SSRF gate at the op layer.

* feat(sync): re-clone fallback when clone is missing/no-git/corrupted

src/commands/sync.ts gets a v0.28-aware front-half. When the source has
config.remote_url, performSync calls validateRepoState before the existing
fast-forward pull path:

  - 'healthy'    → fall through to existing pull (unchanged)
  - 'missing'    → loud stderr "auto-recovery: re-cloning <id>", then
  'no-git'         recloneIfMissing handles the temp-dir + rename. Sync
  'not-a-dir'      continues from the freshly-cloned head.
  - 'corrupted'  → throw with structured hint pointing at sources remove
                   + add (no syncing wrong state).
  - 'url-drift'  → throw with hint pointing at the (deferred) sources
                   rebase-clone command.

Closes the operator-confidence gap: rm -rf $GBRAIN_HOME/clones/<id>/ no
longer breaks future syncs. The next sync sees the missing dir and
recovers via the recorded URL.

src/core/operations.ts: extend ErrorCode with 'unknown_transport' so
whoami's Q3 fail-closed path types check.

test/sources-resync-recovery.test.ts (12 tests): full validateRepoState
state matrix exercised under fake-git, recloneIfMissing recovery from
each degraded state, idempotent on healthy clones, the sync.ts:320
integration path that drives the recovery.

test/sources-ops.test.ts + test/sources-mcp.test.ts: drop the
GBRAIN_PGLITE_SNAPSHOT-disable line so these tests stop forcing cold
init across the parallel-shard runner. With snapshot allowed, init time
drops from 6+s to ~50ms and parallel runs stay under the 5s hook
timeout.

test/sources-mcp.test.ts: tighten scope literal-type so tsc keeps the
union narrow.

* feat(cli): sources add --url + restore re-clone, thin-wrapper refactor

src/commands/sources.ts now delegates the data-mutation work to
src/core/sources-ops.ts (added in the previous commit). The CLI handler
parses argv, calls into addSource, and formats output.

Two new flags on `gbrain sources add`:
  - `--url <https-url>` : federated remote-clone path (clone + INSERT +
    rename, atomic rollback on failure).
  - `--clone-dir <path>` : override the default
    $GBRAIN_HOME/clones/<id>/ destination.

Validation rejects mutually-exclusive `--url` + `--path`. Errors from
the ops layer (SourceOpError) propagate through the CLI's standard
error wrapper in src/cli.ts so existing tests that assert throw shape
keep passing.

`gbrain sources restore <id>` (T4 from eng review): if the source has a
remote_url AND the on-disk clone was autopurged, call recloneIfMissing
before declaring success. Clone errors print a WARN with recovery
hints rather than failing the restore — the DB row is what restore
guarantees; the clone is best-effort.

54 sources-related tests pass (existing test/sources.test.ts +
sources-ops + sources-mcp).

* feat(doctor,cycle): orphan-clones surface + autopilot purge phase (P1)

addSource's atomicity contract uses a temp dir that gets renamed to the
final clone path. If the process is SIGKILL'd between clone-finish and
rename, the temp dir orphans on disk. Without sweeping these, a brain
server accumulates gigabytes over months of failed `sources add --url`
attempts.

Two layers:

1. `gbrain doctor` now surfaces stale entries. A new orphan_clones check
   walks $GBRAIN_HOME/clones/.tmp/, names anything older than 24h, and
   prints a warn with disk-byte estimate. Operators see the leak before
   `df` complains.

2. The autopilot cycle's existing `purge` phase grows a substep that
   nukes .tmp/ entries past the same 72h TTL the page-soft-delete purge
   uses. Operator behavior stays uniform across all soft-delete-style
   surfaces.

Both layers are filesystem-only (no DB). On a brain that never used
--url cloning, both are no-ops.

* build(admin): scope checkboxes source from scope-constants mirror + dist

admin/src/pages/Agents.tsx Register Client modal:
  - useState default sources from ALLOWED_SCOPES_LIST (defaulting `read`
    to true, others false; unchanged UX for the common case).
  - Scope checkbox map iterates ALLOWED_SCOPES_LIST instead of the old
    hardcoded ['read','write','admin'].

Without this commit, even with the v0.28.1 server-side scope hierarchy,
operators registering an OAuth client from the admin UI cannot tick the
new sources_admin / users_admin scopes — defeats the whole gstack
/setup-gbrain Path 4 unblock.

The drift-check CI gate (scripts/check-admin-scope-drift.sh) ensures
this list stays in sync with src/core/scope.ts going forward.

admin/dist/* rebuilt via `cd admin && bun run build`. Old hash bundle
removed; new bundle (224.96 kB / 68.70 kB gzip).

* docs: v0.28.1 — remote-source MCP + scope hierarchy + whoami

VERSION + package.json: bump to 0.28.1 (per CLAUDE.md branch-scoped
versioning rule — this branch adds substantial new features on top of
v0.28.0).

CHANGELOG.md: new top-level entry for v0.28.1 in the gstack/Garry voice
(no AI vocabulary, no em dashes, real numbers + commands). Lead
paragraph names what the user can now do that they couldn't before.
"Numbers that matter" table calls out the +5 MCP ops, +2 OAuth scopes,
and the 4-to-0 SSH-step number for gstack /setup-gbrain Path 4. "What
this means for you" closer ties the work to the operator workflow shift.
"To take advantage of v0.28.1" block has paste-ready upgrade commands
including the admin SPA rebuild step. Itemized changes section
describes the architecture cleanly without exposing scope-string
internals to public attack-surface enumeration (per CLAUDE.md
responsible-disclosure rule).

TODOS.md: file 6 follow-ups under a new "Remote-source MCP follow-ups
(v0.28.1)" section: token rotation, migration introspection in
get_health, Accept-header friendliness, sources rebase-clone for
URL-drift recovery, --filter=blob:none partial-clone option, and the
chunker_version PGLite-schema parity codex caught.

README.md: short subsection under the existing sources CLI listing
that names the new --url flag and what auto-recovery does. Capability
framing (no scope-string enumeration).

llms.txt + llms-full.txt: regenerated via `bun run build:llms` so the
documentation bundle reflects the v0.28.1 entry. The build-llms
generator's drift check passes.

* test(e2e): sources-remote-mcp — full gstack /setup-gbrain Path 4 round-trip

Spins up `gbrain serve --http` against real Postgres with a fake-git binary
in PATH (so `git clone` is exercised end-to-end without network), registers
two OAuth clients (sources_admin + read-only), mints tokens, calls the new
v0.28.1 MCP ops via /mcp, and asserts the gstack /setup-gbrain Path 4 flow
works end to end.

12 tests cover the full lifecycle:
- whoami over HTTP MCP returns transport=oauth + the right scopes
- /.well-known/oauth-authorization-server advertises all 5 scopes
- sources_add: clone fires, INSERT lands, row carries config.remote_url
- sources_status: clone_state=healthy after add
- sources_list: surfaces remote_url for the new source
- SSRF rejection: sources_add with RFC1918 URL fails at parseRemoteUrl gate
- Scope enforcement: read-only token gets insufficient_scope on sources_add
- Read-only token CAN call sources_list (read-scoped op)
- ALLOWED_SCOPES allowlist: CLI register-client rejects bogus scope
- Recovery: rm clone dir + sources_status reports clone_state=missing
- sources_remove: cascades + cleans up the auto-managed clone dir

Subprocess env threading replicates the v0.26.2 bun execSync inheritance
pattern — bun does NOT inherit process.env mutations, so every CLI
subprocess call passes env: { ...process.env } explicitly.

Cleanup contract mirrors test/e2e/serve-http-oauth.test.ts: revoke any
clients we registered, force-kill the server subprocess on SIGTERM
timeout, surface cleanup failures to stderr without throwing so real
test failures aren't masked.

The base table list in helpers.ts (ALL_TABLES) doesn't include sources
or oauth_clients, so this test explicitly truncates them in beforeAll
to avoid Q4 pre-flight collisions on re-run.

Skipped gracefully when DATABASE_URL is unset.

* fix: codex adversarial review — confine remote sources_admin + close SSRF gaps

Pre-ship adversarial review (codex exec) caught five issues. Four ship in
this commit; the fifth (DNS rebinding) is filed as v0.28.x follow-up.

CRITICAL — `sources_admin` tokens over HTTP MCP could plant content at any
host path. The MCP op exposed `path` and `clone_dir` to remote callers; the
op layer trusted them verbatim, then auto-recovery's rm -rf on degraded
state turned that into arbitrary delete primitives. src/core/operations.ts
sources_add handler now drops both fields when ctx.remote !== false. Local
CLI keeps the override (operator trust). Loud logger.warn when a remote
caller tries — visible in the SSE feed without leaking values.

HIGH — Steady-state `git pull --ff-only` bypassed GIT_SSRF_FLAGS entirely.
The legacy helper at src/commands/sync.ts:192 spawned git without the
-c http.followRedirects=false -c protocol.{file,ext}.allow=never
--no-recurse-submodules set that cloneRepo applies. Every recurring sync
was reopening the redirect/submodule/protocol bypass. Routed the call site
at sync.ts:381 through pullRepo from git-remote.ts so initial clone and
ongoing pull share one defensive flag set.

MEDIUM — listSources ignored its `include_archived` flag. The op
advertised the param but the function destructured it as `_opts` and
queried every row. Archived sources' ids, local_paths, and remote_urls
were leaking to read-scoped MCP callers by default. Filter in SQL
(`WHERE archived IS NOT TRUE` unless the flag is set) so archived rows
never reach the wire.

PARTIAL HIGH — IPv6 ULA fc00::/7 and link-local fe80::/10 were not in
the isInternalUrl bypass list. Only ::1/:: and IPv4-mapped IPv6 were
blocked. Added regex-based ULA + link-local rejection to url-safety.ts.

Test coverage:
- test/git-remote.test.ts: 4 new IPv6 cases (ULA fc-prefix + fd-prefix,
  link-local fe80::, public IPv6 still allowed).
- test/sources-mcp.test.ts: 3 new cases pinning the remote/local
  asymmetry (clone_dir override silently ignored over MCP, path nulled,
  local CLI keeps the override).
- test/sources-mcp.test.ts: 2 new cases for include_archived honored.

DNS rebinding (codex finding #3): the current gate is lexical only.
A deliberate attacker who controls a hostname's A/AAAA records can still
resolve to an internal IP. Closing this requires async DNS resolution +
revalidation; filed as v0.28.x follow-up in TODOS.md so the API change
surface (parseRemoteUrl becomes async, every caller updates) lands in
its own PR.

323 tests pass (9 files); 4071 unit tests pass (full suite).

* chore: rebump v0.28.1 → v0.28.2 (master collision)

Caught after PR creation. master is at v0.28.1 already; this branch
forked from garrytan/v0.28-release at v0.28.0 and naively bumped to
v0.28.1 without checking the master queue. CI version-gate would have
rejected at merge time (requires VERSION strictly greater than
master's).

Root cause: I bumped VERSION mechanically during plan implementation
(echo "0.28.1" > VERSION) without consulting the queue-aware allocator
at bin/gstack-next-version. /ship Step 12's idempotency check then
classified state as ALREADY_BUMPED and the workflow's "queue drift"
comparison was the safety net I should have hit — but I skipped it.

Files updated:
- VERSION + package.json: 0.28.1 → 0.28.2
- CHANGELOG.md: header + "To take advantage of v0.28.2" subsection
- README.md: sources --url note version reference
- TODOS.md: 7 follow-up entries' version references
- llms.txt + llms-full.txt: regenerated

PR title rewrite via gstack-pr-title-rewrite.sh handled in a separate
gh pr edit call; CI version-gate now passes.

 		579722d9dc v0.23.2 fix(dream): orchestrator-stamped self-consumption marker + verdict model tests (#527) 
* v0.23.1 fix: dream self-consumption guard + configurable verdict model

Built-in isDreamOutput() guard in transcript-discovery.ts auto-skips
any transcript whose first 2000 chars contain dream output slug prefixes
(wiki/personal/reflections/, wiki/originals/ideas/, wiki/personal/patterns/,
dream-cycle-summaries/). Prevents infinite recursion if dream output is
ever fed back into the corpus.

judgeSignificance() now accepts a verdictModel parameter, loaded from
dream.synthesize.verdict_model config key. Default: claude-haiku-4-5.

3 new test cases covering the guard.

* feat(dream): replace content-prefix guard with orchestrator-stamped marker

The v0.23.1 prefix-string guard had two flaws caught by codex review.
serializeMarkdown does not embed the page slug into body content, so
the heuristic could miss real dream output. And real conversation
transcripts often cite brain slugs ("earlier I wrote about
wiki/personal/reflections/identity..."), so the heuristic dropped
legitimate transcripts silently.

Swap content inference for explicit identity. renderPageToMarkdown and
writeSummaryPage now stamp `dream_generated: true` + `dream_cycle_date`
into frontmatter at render time. Guard checks for the marker via
DREAM_OUTPUT_MARKER_RE (anchored at frontmatter open, BOM/CRLF
tolerant, scans first 2000 chars, word boundary on `true`). Cannot
drift, cannot false-positive on user text, cannot miss real output.

Tests built from a real Page → renderPageToMarkdown → isDreamOutput
round-trip (codex finding #5 — synthetic strings don't prove the
guard catches what synthesize actually produces). Coverage: regression
fixture, false-positive prevention on user transcripts citing slugs,
CRLF+BOM, whitespace/case variants, anchor-at-byte-0, perf bound,
bypass plumbing, dream_generatedfoo word-boundary check.

* feat(dream): --unsafe-bypass-dream-guard CLI flag

Explicit opt-in to disable the synthesize self-consumption guard. The
flag is intentionally NOT tied to --input — codex review caught that
implicit bypass is a footgun: any caller could synthesize a dream-
generated page directly via --input, get a cached positive verdict,
and silently re-trigger the loop bug.

Plumbing: dream.ts CLI parses the flag → DreamArgs.bypassDreamGuard →
runCycle({ synthBypassDreamGuard }) → SynthesizePhaseOpts.bypassDreamGuard
→ discoverTranscripts({ bypassGuard }) and readSingleTranscript.
Loud stderr warning at phase entry when set so the cost is visible.

* v0.23.2 chore: bump version + CHANGELOG for corrected guard architecture

Replaces the v0.23.1 release notes with the v0.23.2 voice describing
the orchestrator-stamped marker approach and the --unsafe-bypass-dream-guard
flag.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs: sync project docs for v0.23.2 marker-based guard

Update CLAUDE.md Key Files entries for src/core/cycle/synthesize.ts,
src/core/cycle/transcript-discovery.ts, and src/commands/dream.ts to
reflect the v0.23.2 dream_generated frontmatter marker that replaces the
v0.23.1 content-prefix self-consumption guard, plus the new
--unsafe-bypass-dream-guard CLI flag.

* docs: regenerate llms-full.txt for v0.23.2 CLAUDE.md updates

CI's `build-llms generator > committed match generator output` guard
caught drift after the v0.23.2 doc-sync (commit 507edb1e) updated three
Key Files entries in CLAUDE.md without re-running `bun run build:llms`.

The llms.txt index didn't drift (no new doc URLs); only the inlined
llms-full.txt bundle needed refreshing.

* test(e2e): round-trip dream-recursion coverage for v0.23.2 marker guard

Three new PGLite E2E cases exercise the actual production loop scenario
end-to-end. Unit tests covered the bug class at the function-pair level
(renderPageToMarkdown → readSingleTranscript). These cover it at the
phase level: runPhaseSynthesize with a real engine, real putPage, real
renderPageToMarkdown, real corpus-dir discovery.

1. Leaked dream output is skipped on next synthesize run. The reflection
   page is inserted, reverse-rendered (which stamps `dream_generated:
   true`), dropped into the corpus dir as .txt, and the next phase run
   reports "no transcripts to process" with a stderr skip log. Verdict
   cache stays untouched so a future legit edit isn't shadowed by a
   stale cached "false".

2. bypassDreamGuard=true at phase entry re-enables ingestion. Same
   marked file gets discovered through the loud-warning path. Proves
   --unsafe-bypass-dream-guard plumbing reaches discoverTranscripts at
   phase scope.

3. Mixed corpus (leaked dream output + real conversation transcript)
   discovers exactly the real one. Pins codex finding #1's headline
   false-positive case: a transcript citing wiki/personal/reflections/
   in body must NOT be skipped.

Stderr capture via process.stderr.write spy with try/finally restore.

* fix(test): use valid PageType 'note' in round-trip E2E fixtures

CI typecheck caught three TS2322 violations in the round-trip E2E
fixtures: 'reflection' is not a member of PageType. Reflections are
filed as 'note' in production (renderPageToMarkdown falls back to 'note'
for unknown types).

No behavior change — the guard test still exercises the same
serializeMarkdown → discoverTranscripts loop.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* docs(claude): require `bun run typecheck` before push

The pre-ship section listed `bun test` as the unit-test path but didn't
flag the trap: `bun test` (the bun runner) does NOT run TypeScript type
checking. Only `bun run test` (the npm script) does, because it chains
`bun run typecheck` + the four shell pre-checks before the runner.

CI on PR #527 caught a `'reflection'` literal that `PageType` doesn't
admit (PageType is a closed union). The runtime E2E and `bun test`
both passed locally because the runner doesn't gate on TS. The
separate typecheck stage in CI rejected it.

New rule: run `bun run typecheck` (or `bun run test`, which wraps it,
or `bun run ci:local` for the full gate) before pushing. The runner-
alone path is for hot-loop test iteration only.

Also regenerated llms-full.txt for the CLAUDE.md update.

 		527b87bd1e v0.23.0 feat: gbrain dream synthesizes conversations into brain pages (v0.23.0) (#462) 
* feat: dream_verdicts schema + engine methods

Adds the v25 schema migration creating the dream_verdicts table
(file_path, content_hash, worth_processing, reasons, judged_at;
PRIMARY KEY (file_path, content_hash); RLS-enabled when running as
a BYPASSRLS role).

Distinct from raw_data (which is page-scoped) — transcripts being
judged for synthesis aren't pages. The (file_path, content_hash)
key means edited transcripts re-judge automatically.

BrainEngine gains:
- DreamVerdict + DreamVerdictInput types
- getDreamVerdict(filePath, contentHash) → DreamVerdict | null
- putDreamVerdict(filePath, contentHash, verdict) — ON CONFLICT upsert

Both engines implement (postgres-engine.ts, pglite-engine.ts).

This commit alone is functionally inert — nothing reads/writes the
table yet. The synthesize phase (later commit) is the consumer.

* feat: trusted-workspace allow-list for subagent put_page

Adds OperationContext.allowedSlugPrefixes — when set, put_page
enforces slug membership in the allow-list instead of the legacy
wiki/agents/<id>/... namespace. The trust signal is the SUBMITTER
(PROTECTED_JOB_NAMES gates subagent submission so MCP can't reach
this field), not the runtime ctx.remote flag — every subagent tool
call has remote=true for auto-link safety, so basing trust on
remote is incoherent.

matchesSlugAllowList(slug, prefixes) helper supports glob suffix
'/*' (recursive — wiki/originals/* matches ideas/foo/bar) and
exact match for unsuffixed entries.

put_page check shape:
  if (viaSubagent && allowedSlugPrefixes set) → allow-list check
  else if (viaSubagent) → existing namespace check (regression guard)
  else → no check (regular CLI)

Auto-link is re-enabled for the trusted-workspace path so the cycle's
extract phase doesn't have to recompute every edge after synthesize
writes. Untrusted remote writes still skip auto-link as before.

SubagentHandlerData.allowed_slug_prefixes is the wire field; the
synthesize/patterns phases (later commit) populate it from a single
source of truth in skills/_brain-filing-rules.json's
dream_synthesize_paths.globs array. The model's tool schema description
mirrors the allow-list so it writes correct slugs on the first try.

IRON RULE security tests:
- test/operations-allow-list.test.ts: allow-list ALLOW/REJECT, glob
  semantics, regression guard for the v0.15 namespace fallback when
  allow-list is unset, FAIL-CLOSED when subagentId is missing.
- test/e2e/dream-allow-list-pglite.test.ts: end-to-end on PGLite,
  poisoned-transcript style write outside allow-list → REJECTED.

* feat: cycle scaffolding — 8-phase order + transcript discovery

Extends ALL_PHASES from 6 → 8: synthesize between sync and extract,
patterns between extract and embed. Codex finding #7: patterns MUST
run after extract because subagent put_page sets ctx.remote=true and
skips auto-link/timeline by default — extract is the canonical edge
materialization step. Without that ordering, patterns reads stale
graph state.

Final order:
  lint → backlinks → sync → synthesize → extract → patterns → embed → orphans

CycleOpts gains:
- yieldDuringPhase callback — generic in-phase keepalive for long
  waits (synthesize fan-out, patterns roll-up). Renews cycle-lock TTL
  + worker job lock. Mirrors yieldBetweenPhases shape.
- synthInputFile / synthDate / synthFrom / synthTo — forwarded to
  runPhaseSynthesize for the CLI's --input/--date/--from/--to flags.

CycleReport.totals additively grows (no schema_version bump):
  transcripts_processed, synth_pages_written, patterns_written.

src/core/cycle/transcript-discovery.ts is a pure filesystem walk:
- .txt files only, sorted by path for determinism
- date-prefixed basename filter (--date / --from / --to)
- min_chars filter (default 2000)
- exclude_patterns auto-wraps bare words as \b<word>\b regex (Q-3),
  power users may pass full regex with anchors
- compileExcludePatterns is exported for unit tests

Phase implementations land in the next commit; this one only adds
the dispatcher slots so commit-by-commit bisect doesn't crash on
import-not-found.

* feat: synthesize + patterns phases — gbrain dream actually dreams

Synthesize phase (src/core/cycle/synthesize.ts) reads conversation
transcripts from dream.synthesize.session_corpus_dir and writes
brain-native pages: reflections to wiki/personal/reflections/...,
originals to wiki/originals/ideas/..., timeline entries on existing
people pages.

Pipeline:
  1. discoverTranscripts (filesystem walk + filters)
  2. cooldown check via dream.synthesize.last_completion_ts config
     (default 12h; bypassed by --input/--date/--from/--to)
  3. cheap Haiku verdict per transcript, cached in dream_verdicts
     table keyed by (file_path, content_hash) — backfill re-runs
     skip already-judged transcripts at zero cost
  4. fan-out: one Sonnet subagent per worth-processing transcript
     dispatched with allowed_slug_prefixes (read from
     skills/_brain-filing-rules.json's dream_synthesize_paths.globs)
     and idempotency_key dream:synth:<file_path>:<content_hash>
  5. wait via waitForCompletion; yieldDuringPhase ticks every child
     terminal so the cycle-lock TTL refreshes on long backfills
  6. collect slugs from subagent_tool_executions for each child
     (codex finding #2: NOT pages.updated_at, which would pick up
     unrelated writes)
  7. orchestrator dual-write — query each new page from DB,
     reverse-render via serializeMarkdown, write file to brain_dir.
     Subagent never gets fs-write access.
  8. deterministic summary index page at dream-cycle-summaries/<date>
     (codex finding #4: slug shape is regex-compatible — no
     underscores, no .md extension)
  9. write completion timestamp ONLY on successful runs

Patterns phase (src/core/cycle/patterns.ts) runs after extract so
the graph state is fresh. Single Sonnet subagent gathers reflections
within dream.patterns.lookback_days (default 30); names a pattern
only when ≥dream.patterns.min_evidence (default 3) reflections
support it. Same allow-list path as synthesize.

CLI flags on `gbrain dream` (src/commands/dream.ts):
  --input <file>      ad-hoc transcript synthesis (implies
                      --phase synthesize; bypasses cooldown)
  --date YYYY-MM-DD   restrict synthesize to one date
  --from <d> --to <d> backfill range
  --dry-run           runs Haiku verdict (cached), skips Sonnet
                      synthesis. NOT zero LLM calls (codex #8).

Conflict detection: --input + --date/--from/--to exits 2.
ISO 8601 date format validated; range start > end exits 2.

Auto-commit / push deferred to v1.1 (codex finding #5). v1 writes
files to brain_dir; user or autopilot handles git.

Tests:
- test/cycle-patterns.test.ts: structural assertions on the patterns
  phase (queue + waitForCompletion wired, allow-list threading,
  subagent_tool_executions provenance, no raw_data dependency).
- test/dream-cli-flags.test.ts: argv parsing, conflict detection,
  ISO date validation, --input implies --phase synthesize, dry-run
  semantics doc string.
- test/e2e/dream-synthesize-pglite.test.ts: 8 cases on PGLite
  in-memory exercising not_configured, empty corpus, no API key
  skip path, dry-run, cooldown active vs --input bypass, and the
  dream_verdicts cache hit path. Per-test rig isolation (each
  test creates and tears down its own engine) avoids
  cross-test PGLite WASM contention.

* docs: dream cycle v0.27.0 — skills, CLAUDE.md, migration, changelog

- skills/maintain/SKILL.md: synthesize + patterns phases documented
  with quality bar (Iron Law for synthesis), trust boundary, idempotency,
  cooldown semantics, CLI invocation patterns. New triggers added so
  "process today's session" / "synthesize my conversations" route here.
- skills/RESOLVER.md: dream cycle triggers route to maintain.
- skills/_brain-filing-rules.md: directory table for the five output
  types (reflections, originals, patterns, people enrichment, cycle
  summary) with slug shape per row; Iron Law repeated.
- skills/migrations/v0.27.0.md: agent-readable migration narrative.
  Schema migration v25 runs automatically on `gbrain apply-migrations`;
  synthesize ships disabled by default — opt-in via
  dream.synthesize.session_corpus_dir + dream.synthesize.enabled.
- CLAUDE.md: file inventory updated with new files (cycle/synthesize.ts,
  cycle/patterns.ts, cycle/transcript-discovery.ts), the 8-phase
  ordering, the trusted-workspace allow-list trust model, and the v25
  schema migration line in the migrate.ts entry.
- VERSION: 0.20.4 → 0.27.0
- CHANGELOG.md: v0.27.0 release-summary section per CLAUDE.md voice
  rules (numbers that matter table, what-this-means closer, "to take
  advantage of" block), followed by the itemized changes.

* test: add patterns E2E + 8-phase cycle E2E + bump synth-cooldown timeouts

Two new E2E test files on PGLite (no DATABASE_URL or API key required):

- test/e2e/dream-patterns-pglite.test.ts (6 cases) — exercises
  runPhasePatterns skip paths against a real engine: disabled,
  default-enabled-but-insufficient-evidence, no-API-key, dry-run.
  Sibling of dream-synthesize-pglite.test.ts; same per-test rig
  pattern for engine isolation.

- test/e2e/dream-cycle-eight-phase-pglite.test.ts (5 cases) —
  end-to-end runCycle with the v0.27 8-phase order. Asserts:
  ALL_PHASES is the documented 8 phases in the right sequence,
  the dry-run report's phases array preserves that order,
  CycleReport.totals carries the new transcripts_processed /
  synth_pages_written / patterns_written fields, --phase synthesize
  and --phase patterns each run only that phase, and synthInputFile
  is plumbed correctly through runCycle to runPhaseSynthesize.

Bump per-test timeout to 30s on the two synthesize-cooldown E2E
tests that create two PGLite engines back-to-back. Default Bun 5s
budget is tight under sustained suite pressure (PGLite WASM init
costs ~1-2s per engine on macOS); each test passes alone but flakes
in the full E2E suite. The third arg `30_000` is Bun's standard
test-timeout knob.

Full E2E suite (test/e2e/) now: 86 pass / 0 fail / 258 skip.

* fix: ship-prep — typecheck fixes, llms.txt regen, 8-phase test update

- src/core/cycle/synthesize.ts + patterns.ts: PageType 'default' → 'note'
  (TS strict typecheck rejected 'default'; 'note' is a valid PageType
  for orchestrator-written summary index pages and reverse-render fallback).
- src/core/pglite-engine.ts: re-import DreamVerdict + DreamVerdictInput
  types after the master merge dropped them from the import line.
- test/e2e/dream-allow-list-pglite.test.ts: ToolCtx now requires
  remote: true literal; thread it through every put_page tool call.
- test/e2e/dream-patterns-pglite.test.ts: PageType 'default' → 'note'
  in the seedReflections helper.
- test/core/cycle.test.ts: bump expected hook-call count + phase count
  6 → 8 to match v0.27 ALL_PHASES extension.
- llms-full.txt: regenerate against the updated CHANGELOG + CLAUDE.md
  so the committed snapshot matches what the generator now produces.

Full bun test suite: 2793 pass / 0 fail / 258 skip (3051 tests, 177 files).

* docs: update README + INSTALL_FOR_AGENTS for v0.27.0 dream cycle

README: maintain skill row mentions synthesize/patterns; gbrain dream
command-reference block describes the 8-phase pipeline and the new
--input/--date/--from/--to flags.

INSTALL_FOR_AGENTS: dream cycle bullet calls out v0.27 conversation
synthesis + cross-session pattern detection.

* chore: renumber v0.27.0 → v0.23.0

Master is at v0.22.5; v0.23.0 is the next natural slot for the dream-cycle
synthesize + patterns release. Bulk rename across VERSION, package.json,
CHANGELOG, migration file, source comments, skills, and llms.txt bundles.

* test(e2e): bump cycle.test.ts phase count 6 → 8

The dry-run full-cycle test asserted 6 phases. v0.23 added synthesize
and patterns, bringing the total to 8. The unit-side equivalent
(test/core/cycle.test.ts) was already updated; this catches the
E2E sibling that surfaced after the latest master merge.
