d0d0e2a64a v0.37.11.0: fresh-install PGLite embedding setup fix wave (#1286)
* chore(test): preload gateway to OpenAI/1536 so 1536-dim test fixtures keep working

The v0.37 fix wave changes the canonical gateway defaults to
zeroentropyai:zembed-1 / 1280 (matching what v0.36 already chose as the
system default). 20+ test files have hardcoded new Float32Array(1536)
fixtures that match the OLD schema default. Without this preload, those
tests fail with a vector-dim-mismatch on insert.

The preload is gateway-only — it doesn't change which model gbrain ships
to production users. Tests that want the new ZE/1280 defaults call
configureGateway() explicitly in their own beforeAll.

* feat(ai): canonical embedding defaults + sweep across schema/engines/registry

Closes the v0.36 defaults drift bug class. The gateway shipped
zeroentropyai:zembed-1 / 1280 as the system default in v0.36 but eight
other places kept hardcoding 1536 / text-embedding-3-large. Fresh
gbrain init --pglite sized the column to 1536, the embed pipeline used
ZE/1280, and every page failed with dim mismatch.

- New src/core/ai/defaults.ts leaf module is the canonical source for
  DEFAULT_EMBEDDING_MODEL / DEFAULT_EMBEDDING_DIMENSIONS. Schema and
  registry helpers import from this lean module instead of pulling the
  full gateway (which loads every provider SDK).
- src/core/ai/gateway.ts re-exports the constants for back-compat.
- src/core/pglite-schema.ts getPGLiteSchema() defaults track gateway.
- src/core/postgres-engine.ts getPostgresSchema() default args track
  gateway (same drift on the Postgres path — codex round 1 CDX-1).
- Both engine.initSchema() fallbacks track gateway constants (no more
  stale OpenAI/1536 catch-block defaults).
- Schema seed stops stripping the provider prefix; full provider:model
  is stored in the DB config table (codex round 1 CDX-4).
- Chunk-row INSERT defaults track gateway (codex round 2 CDX2-4 —
  pglite-engine:1611 + postgres-engine:1647 were production write
  sites previously hardcoded to text-embedding-3-large).
- src/core/search/embedding-column.ts loadRegistry + isCacheSafe gain
  the cfg > gateway > DEFAULT resolution chain (codex round 2 CDX2-3).
  The gateway tier matters because callers that configure the gateway
  (init paths, tests, programmatic SDK) expect the registry to mirror
  that state when cfg doesn't have an explicit embedding_model.

Tests:
- schema-templating: default expectation flips to ZE/1280 (v0.37 truth).
- embedding-dim-check: 3 new engine-kind branching cases + updated
  fresh-brain expectation (under legacy preload).
- embedding-column: registry + isCacheSafe expectations match new chain.
- v0_28_5-fix-wave E2E: engineKind required arg propagated.

* feat(init+config+cli): always-configure gateway, file-only loader, honest config-set, sync/reinit help

Closes the "fresh init doesn't work + config-set silently lies" bug
class end-to-end. Six related changes that ship together because the
file-plane/DB-plane contract only holds when init paths, config-set,
the gateway env mapping, and the recipe text all agree.

Lane B (init paths):
- initPGLite, initPostgres, initMigrateOnly always configureGateway()
  before engine.initSchema(). Pre-fix the call was gated on flags, so
  bare `gbrain init --pglite` left the gateway unconfigured and the
  engine fell through to stale OpenAI/1536 defaults instead of the
  ZE/1280 the gateway would have resolved.
- New configureGatewayWithMergedPrecedence() helper applies the locked
  precedence chain `CLI > env > existing file > gateway internal`.
- printResolvedAIChoice() shows the resolved model/dim at init time +
  surfaces a ZE setup hint inline when the API key is missing.
- B.4: saveConfig merge uses loadConfigFileOnly() so transient env
  state (DATABASE_URL, etc.) never poisons ~/.gbrain/config.json
  (codex round 2 CDX-5).
- B.5: extend the v0.28.5 dim-mismatch detector so it fires when the
  gateway-resolved dim differs from the existing column, not only
  when --embedding-dimensions is explicit (codex round 2 CDX-6).

Lane C (config plane):
- New `loadConfigFileOnly()` reads ~/.gbrain/config.json only — no env
  merge, no DATABASE_URL inference. Safe write-back source for init.
- GBrainConfig gains `zeroentropy_api_key?: string`. loadConfig merges
  process.env.ZEROENTROPY_API_KEY. buildGatewayConfig at cli.ts:1401
  maps it into env.ZEROENTROPY_API_KEY so ZE recipes finally see it
  (codex round 2 CDX2-5+6 — the v1 fix landed in the wrong file).
- `gbrain config set embedding_model` and `... embedding_dimensions`
  refuse unconditionally and print a paste-ready wipe-and-reinit
  recipe. No --force escape (codex round 2 CDX2-13).
- migrate-engine.ts adds a contract comment at the DB-plane write
  site documenting "DB stores schema-applied metadata; file plane is
  canonical for runtime gateway config" + preserves the existing
  file-plane config across engine migration.

Lane D.1 (recipe text):
- embeddingMismatchMessage() takes an `engineKind` arg. PGLite branch
  emits a wipe-and-reinit recipe using gbrainPath('brain.pglite') or
  the caller's databasePath override. Postgres branch keeps the SQL
  ALTER recipe.
- The PGLite recipe recommends `gbrain reinit-pglite` (new sugar
  command below) as the one-line path before falling back to the
  by-hand mv + init + sync sequence.

Lane D.4 (sync help dispatch):
- `sync` and `reinit-pglite` added to CLI_ONLY_SELF_HELP so their own
  --help branches reach the user (pre-fix the generic short-circuit
  fired first and the dedicated usage was unreachable; codex round 2
  CDX2-12).
- `gbrain sync --help` short-circuits BEFORE engine bind so users on
  a fresh tmpdir (no config) can read the help without hitting
  no-such-config errors.

Sugar:
- New `gbrain reinit-pglite --embedding-model X --embedding-dimensions N`
  wraps the wipe + init + sync dance into one command. Backs up the
  brain to <path>.bak. TTY confirmation unless --yes. --no-sync to
  defer the resync. --json for scripts.

Tests:
- test/cli.test.ts sync-help test rewritten for the new
  per-command-usage output (lists --no-embed which is the v0.37
  user-visible flag the wave wanted to surface).

* feat(embed+sync): pre-flight dim-mismatch guard + sync hint at both catch sites

embedding-pipeline error UX. Pre-fix, a fresh-install dim mismatch
produced raw Postgres "expected N dimensions, not M" errors page after
page, surfacing only after the worker pool drained the entire corpus.
Sync swallowed embed errors at TWO catch sites and never surfaced
the recovery recipe.

embed.ts:
- New `EmbeddingDimMismatchError` tagged class with the paste-ready
  recipe baked in.
- `runEmbedCore` pre-flights via `readContentChunksEmbeddingDim` +
  gateway.getEmbeddingDimensions() before the worker pool spins up.
  On mismatch, throws the typed error which the CLI wrapper catches
  and prints. Dry-run skips the check (no embed risk).
- Catches the headline fresh-install bug class at first call instead
  of letting it hammer N parallel API calls into dim-rejected inserts.

sync.ts:
- Both embed catches at sync.ts:990 (incremental) and sync.ts:1129
  (first-sync) detect EmbeddingDimMismatchError and surface the recipe
  + a `--no-embed` tip on stderr (codex round 2 CDX2-8: incremental
  path was previously silent; only the first-sync path was flagged).
- Non-mismatch embed failures still stay best-effort (rate limits,
  transient network) — those shouldn't break sync.
- Sync calls runEmbedCore directly instead of runEmbed (which calls
  process.exit on error and bypasses sync's catch).
- Sync gets a proper --help block listing every meaningful flag:
  --no-embed, --workers, --source, --skip-failed, --retry-failed,
  --watch, --interval, --no-pull, --all, --json, --yes, --dry-run.

* feat(doctor): read gateway for schema-sizing checks + provider-aware key lookup

Doctor's embedding checks were reading the DB config table for
embedding_model / embedding_dimensions / zeroentropy_api_key. Post
v0.37 the file plane is canonical (the DB plane is schema-applied
metadata, not runtime gateway config) so those reads produced stale
verdicts on fresh installs whose DB row hadn't been written.

- checkEmbeddingWidthConsistency reads gateway.getEmbeddingDimensions()
  and gateway.getEmbeddingModel() instead of engine.getConfig(...).
  Reuses readContentChunksEmbeddingDim from the same shared helper
  init + embed use. On mismatch, the fix hint threads engineKind +
  databasePath into the new branched recipe (codex round 1 CDX-8 +
  Lane E.1/E.2).
- checkZeEmbeddingHealth reads gateway for the model + loadConfigFileOnly
  for the key. Fires when (a) resolved model starts with zeroentropyai:
  AND (b) ZEROENTROPY_API_KEY is unset in env AND (c) file plane has
  no zeroentropy_api_key (codex round 2 CDX2-10).
- loadRecommendationContext reads gateway for both fields and
  recognizes the ZE key alongside OpenAI/Anthropic in the
  hasEmbeddingApiKey check, so brains on ZE no longer look "healthy"
  just because OPENAI_API_KEY happens to be set (codex round 2 CDX2-11).

Tests rewritten for the gateway-source-of-truth contract via
configureGateway() in beforeAll. Added a "gateway unconfigured: skips
with ok" case so doctor doesn't false-warn on cold-boot brains.

* test+docs(v0.37): fix-wave unit coverage + PGLite-first migration recipe + TODOS

Lands the v0.37 PGLite fresh-install fix wave's structural tests and
the user-facing migration recipe overhaul.

test/v0_37_fix_wave.test.ts (new): 22 unit cases pinning the lanes:
- Lane A: defaults module exports, getPGLiteSchema/getPostgresSchema
  default-args, registry + isCacheSafe under the `cfg > gateway >
  DEFAULT` chain (both gateway-set and gateway-reset branches).
- Lane B: loadConfigFileOnly env isolation + DATABASE_URL inference
  refusal + null-on-missing.
- Lane C.3: buildGatewayConfig maps zeroentropy_api_key + process.env
  wins over config (operator escape hatch contract).
- Lane D.2: EmbeddingDimMismatchError shape + tag.
- Lane D.4: structural assertion that `sync` is in CLI_ONLY_SELF_HELP.
- Deferred-TODO ship: reinit-pglite is registered correctly +
  embeddingMismatchMessage PGLite branch recommends it.

docs/embedding-migrations.md: PGLite section moved to top (the default
install). The recommended path is `gbrain reinit-pglite` one-liner;
the by-hand mv + init + sync sequence stays as the fallback recipe.
Postgres SQL ALTER recipe preserved. New section on `gbrain config
set` refusal explains the file-plane vs DB-plane contract so users
don't follow stale documentation.

TODOS.md: 4 deferred follow-ups filed with concrete file pointers:
- gbrain embed --try-fallback (provider auto-switch with consent gate)
- Full plane unification for non-schema-sizing fields
- Worker-pool shared AbortController for mid-run dim drift
- Cleanup of back-compat constants in src/core/embedding.ts

* test(v0.37): fill behavior gaps + headline fresh-install E2E

The structural fix-wave tests in test/v0_37_fix_wave.test.ts pin lane-level
invariants (exports, registry chain, signature shapes). The audit found 10+
END-TO-END behaviors that the structural tests didn't actually reach.
This file fills the highest-leverage gaps.

Unit coverage (test/v0_37_gap_fill.test.ts, 12 cases):
- Lane A.7: chunk-row INSERT default tracks DEFAULT_EMBEDDING_MODEL
  constant (pre-fix this was the literal 'text-embedding-3-large' at
  pglite-engine.ts:1611 + postgres-engine.ts:1647 — production write
  sites that were never directly tested; codex round 2 CDX2-4).
- Lane A.8: schema seed stores full provider:model in DB config
  (pre-fix the .split(':') strip dropped the prefix; codex round 1
  CDX-4). Asserts a fresh ZE init stores `zeroentropyai:zembed-1`
  in the config table, not bare `zembed-1`.
- Lane B precedence: explicit CLI > env > existing file > default
  test (codex round 2 CDX2-7 contradiction guard).
- Lane C.3 env merge: process.env.ZEROENTROPY_API_KEY threads through
  loadConfig → cfg.zeroentropy_api_key; loadConfigFileOnly does NOT.
- Lane D.2 end-to-end: schema=1536 + gateway=1280 →
  EmbeddingDimMismatchError fires AND the embed transport is never
  called (the whole point of pre-flight). Plus dry-run skips the
  check.
- Lane D.3 source-text grep: both sync.ts catch sites detect the
  typed error + the `--no-embed` tip is present (CDX2-8).
- Lane E.4 source-text grep: loadRecommendationContext is
  provider-aware (reads gateway + branches on ZE/OpenAI key).
- reinit-pglite contract: refuses on non-PGLite engines + refuses
  when required flags are missing.

E2E (test/e2e/fresh-install-pglite.test.ts, 2 cases):
- Bare `gbrain init --pglite` produces a `vector(1280)` schema, prints
  the resolved choice, persists defaults to config.json — the headline
  scenario that v0.37 ships to fix.
- init → seed page → embed end-to-end: chunks have non-null
  embeddings; no dim mismatch despite the wave's defaults change.

Both E2E cases are IN-PROCESS (per CDX2-12: CLI-subprocess E2E can't
inherit `__setEmbedTransportForTests`). They run with stubbed transport
returning synthetic 1280-dim vectors so we never hit real provider APIs.

* test(v0.37): defensive gateway restore in reinit-pglite describe block

Adds an afterAll that restores the gateway to OpenAI/1536 (matching the
bunfig preload) at the end of the reinit-pglite describe. Belt-and-
suspenders: earlier describe blocks in this file already restore, but
if the reinit-pglite tests ever start mutating the gateway in the
future, this protects downstream test files in the same bun-test shard
from inheriting a non-default state.

* chore: bump version and changelog (v0.37.10.0)

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* docs: scrub stale config-set recipes for embedding model (v0.37.10.0)

README + topologies + embedding-providers were still pointing users at
`gbrain config set embedding_model X` / `embedding_dimensions N`. As of
v0.37.10.0 those writes are refused — the schema column has to resize
alongside the config. Point at `gbrain reinit-pglite` (PGLite) and the
SQL recipe in `docs/embedding-migrations.md` (Postgres) instead.

* chore: bump version to v0.37.11.0

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* test: quarantine v0.37 fix-wave tests to .serial.test.ts

CI's `check:test-isolation` lint flagged R1 violations (direct
`process.env.GBRAIN_HOME` mutation) in both new fix-wave test files.
Per the documented quarantine pattern in CLAUDE.md, rename to
`*.serial.test.ts` instead of refactoring through `withEnv()` — both
files use beforeEach/afterEach env wiring that's already serial-safe.

54a0629745 v0.37.8.0 feat: voyage-code-3 discoverability + reindex-code cost-preview fix (#1267)
* v0.37.6.0 feat: voyage-code-3 discoverability + reindex-code cost-preview fix

For agents indexing source code with gbrain, the right embedding model
is now obvious — and the brain tells you so out loud. Decision tree +
Topology 3 doc + Topology 3 setup-skill pointer + runtime stderr nudge
from `gbrain reindex --code` against non-code-tuned models. Same diff
fixes the stale hardcoded `text-embedding-3-large` in the cost preview
that would have made the nudge land badly.

Tests: 3 new files (recipe regression, nudge logic + CLI integration,
cost-preview IRON-RULE regression).

* todos: file pre-existing doctor-report-remote score regression (#1215 follow-up)

Noticed during /ship of v0.37.6.0. The skill_brain_first check added in
v0.37.3.0 (#1215) appears to tank the doctor health score on fresh PGLite
test brains, causing test/doctor-report-remote.test.ts:65 to fail with
health_score: 50 (expects >=70). Pre-existing on master; not in this
branch's touch surface.

9a4ae0962e v0.37.2.0: takes_resolution_consistency CHECK accepts 'unresolvable' (#1211)
* v0.36.1.1 hotfix: takes_resolution_consistency CHECK accepts 'unresolvable'

Unblocks production grading scripts that write the judge's 4th verdict
type. Before this fix, every quality='unresolvable' INSERT/UPDATE hit
a CHECK violation — 0 of 34 writes landed in a recent prod run.

Migration v74 widens BOTH:
  - takes_resolution_consistency (table-level CHECK) — admits the
    ('unresolvable', NULL) pair alongside the existing 4 legal shapes
  - resolved_quality column-level CHECK — drops the auto-generated
    name from v37, re-adds as takes_resolved_quality_values with the
    4-state enum

Backward compatible. Existing rows with quality IN (NULL, 'correct',
'incorrect', 'partial') all satisfy the new CHECKs unchanged.

TakesScorecard gains sibling fields unresolvable_count + unresolvable_rate;
the existing `resolved` field deliberately keeps its 3-state meaning
so historical scorecards compare apples-to-apples (T1c sibling-field
design from the eng review).

Pinned by:
  - test/takes-resolution.test.ts — R1-R5 round-trip
  - test/migrate.test.ts — v74 structural assertions + PGLite E2E
    suite exercising all valid + invalid (quality, outcome) shapes

* test(e2e/schema-drift): reset public schema in beforeAll to isolate from caller bootstrap state

Previously the test trusted caller-provided DATABASE_URL to point at a fresh
database. CLAUDE.md's E2E lifecycle prescribes 'gbrain doctor --json' as the
bootstrap step (needed by oauth-related tests for table creation), but doctor
configures the gateway and bakes the configured embedding model into
content_chunks.model DEFAULT during the initial CREATE TABLE.

On re-run, CREATE TABLE IF NOT EXISTS is a no-op and the bootstrapped default
sticks. PGLite (always fresh-in-memory) gets the unconfigured-gateway fallback
'text-embedding-3-large'. The test reported phantom drift:
  pg.default="'zembed-1'::text"  pglite.default="'text-embedding-3-large'::text"

Fix: DROP SCHEMA public CASCADE + CREATE SCHEMA public before pg.initSchema.
Resets every table/index/sequence/constraint added by prior tooling. The PGLite
side is already fresh-per-test by construction.

Verified order-independent:
  - Fresh DB → 6/0 pass
  - After 'gbrain doctor' bootstrap → 6/0 pass
  - Full E2E suite (mechanical + schema-drift) → 84/0 pass

* fix(safety): gate schema-drift DROP SCHEMA + relax TakesScorecard interface

Two findings from Codex adversarial review on the v0.37.0.1 hotfix:

1. **DROP SCHEMA safety gate (P0).** test/e2e/schema-drift.test.ts had an
   unguarded DROP SCHEMA public CASCADE. A developer running the E2E with
   DATABASE_URL pointing at a real brain or staging DB would lose the entire
   public schema. The fix: triple-check before destruction.
   - Parse the DATABASE_URL hostname + db name
   - Allow reset only when: explicit GBRAIN_TEST_DB=1 OR (localhost host AND
     test-shaped db name like gbrain_test, *_test, test_*, *_e2e)
   - Refuse otherwise with a loud paste-ready warning
   - The test still proceeds (the parity check is the fail-safe — if the
     caller already had a fresh DB, parity passes; if not, parity fails
     LOUDLY instead of nuking their data)

   Verified all three branches: localhost+gbrain_test resets (6/0 pass);
   localhost+production_brain refuses + warns (6/0 pass against pre-existing
   schema); GBRAIN_TEST_DB=1 override on production_brain name allows reset.

2. **TakesScorecard interface compat.** Making `unresolvable_count` +
   `unresolvable_rate` required fields on the public TakesScorecard
   interface broke downstream SDK consumers who construct scorecard
   fixtures (gbrain-evals, custom engines). The hotfix shouldn't impose
   a compile-break on hotfix users.

   Fix: make both fields optional (`?: number` / `?: number | null`).
   `finalizeScorecard` still always populates them, so all internal code
   sees the real values. External fixtures that omit them compile cleanly.

* fix(safety,ux): tighten DROP SCHEMA gate + surface unresolvable in scorecard CLI

Second codex adversarial pass on v0.37.0.1 surfaced two residual findings.

**P0 — Safety gate still bypassable.** First-pass safety gate used
`explicitOptIn || (isLocalhost && looksLikeTestDb)` — meaning
`GBRAIN_TEST_DB=1` bypassed BOTH the host check AND the db-name check.
Someone running the E2E with that env set against a production DATABASE_URL
would still nuke their schema. Codex re-flagged it as P0.

Tightened logic: `looksLikeTestDb && (isLocalhost || ciOptIn)`. The db-name
pattern is now the hard floor — `gbrain_test`, `*_test`, `test_*`, `*_e2e`.
GBRAIN_TEST_DB=1 only relaxes the localhost requirement (for CI service-name
hosts). Setting the env on a DATABASE_URL pointing at `production_data` is
explicitly refused with a paste-ready message naming the failed check.

Verified 3 ways:
  - gbrain_test + localhost → resets (6/0 pass)
  - production_data + GBRAIN_TEST_DB=1 → REFUSES with clear message
  - foo_e2e + GBRAIN_TEST_DB=1 → resets (test-shaped name passes)

**P2 — gbrain takes scorecard hides the unresolvable signal.** Early-return
on `resolved === 0` was triggered before the new sibling fields rendered.
A brain with only `quality='unresolvable'` verdicts — the spec's whole
production case — printed "No resolved bets yet" and exited. The
unresolvable_rate field was unreachable from the human CLI unless the user
knew to pass `--json`.

Fix: gate the early-return on `resolved === 0 AND unresolvable_count === 0`.
Render `unresolvable` count + `unresolvable_rate` alongside `partial_rate`
when present. Threshold warn at 30% (mirrors PARTIAL_RATE_WARNING_THRESHOLD)
pointing at retrieval coverage, not prediction accuracy — the actionable
read for high-unresolvable brains.

cdba533a04 v0.36.2.0 feat: ZeroEntropy as default + zero-based README rewrite (#1136)
* feat(dims): OpenAI text-embedding-3 Matryoshka range validation (D13)

dimsProviderOptions now fail-loud at the embed boundary when the
configured embedding_dimensions is outside the model's native range
(1..1536 for -small, 1..3072 for -large). Paste-ready fix hint in the
AIConfigError.fix field. Closes the silent-HTTP-400 path that would
have bit OpenAI-fallback users on v0.36.0.0 ZE-default installs.

16 new test cases in test/ai/dims-openai.test.ts pinning the contract
across native-openai and openai-compatible adapter paths.

* feat(ai): flip defaults to ZeroEntropy zembed-1 1280d + zerank-2 reranker

Default embedding model is now zeroentropyai:zembed-1 at 1280d via
Matryoshka. Real-corpus benchmark: 2.2x faster than OpenAI, 2.6x
cheaper at regular pricing, wins 11/20 head-to-head queries.

1280 is the closest valid ZE Matryoshka step to the prior OpenAI 1536d
default (valid set: 2560/1280/640/320/160/80/40). 1024 (Voyage's step)
is NOT on ZE's list — pinned by AIConfigError fail-loud in dims.ts.

balanced mode bundle now defaults reranker_enabled=true. zerank-2
reshuffles 60% of top-1 results in benchmarks. Missing-key fail-open
contract in src/core/search/rerank.ts handles unauthenticated cases.
Opt out with: gbrain config set search.reranker.enabled false

Existing tests updated (gateway.test.ts, search-mode.test.ts) and a
new test/balanced-reranker-default.test.ts (10 cases) pins the fail-
open invariants.

* feat(retrieval-upgrade): RetrievalUpgradePlanner + interactive prompt UX

New src/core/retrieval-upgrade-planner.ts is the consolidated planner
that computes the brain's pending retrieval-upgrade work (chunker
bumps + ZE switch) in one pass and applies the schema transition +
config updates atomically.

Tagged-union ApplyResult enum (D15): 'applied' | 'skipped_already_
applied' | 'skipped_no_work' | 'declined' | 'planned' | 'failed'.
No string-parsing reasons.

Three config keys (D12): ze_switch_prompt_shown (UI state),
ze_switch_requested (user intent), ze_switch_applied (work done).
Plus ze_switch_previous_snapshot (JSON, full prior config for --undo
per D16) and ze_switch_declined_at (90-day re-ask window).

Schema transition (D18) is atomic: DROP indexes + ALTER COLUMN +
CREATE INDEX inside a single engine.transaction(). HNSW recreation
is part of the same transaction — no silent slow-search window.

C3 eligibility logic: ze_switch_offered iff NOT on ZE + NOT declined
recently + NOT applied + (legacy default OR >100 pages).

C4 cost math: MAX(chunker_pending, dim_pending) not SUM — one
re-embed pass invalidates both surfaces simultaneously.

New src/core/retrieval-upgrade-prompt.ts wires the planner to a
TTY-only interactive prompt with two-line cost split (D10) and
privacy callout for the reranker flip.

Tests: test/retrieval-upgrade-planner.test.ts (24 cases) pins the
state machine. test/asymmetric-encoding-contract.test.ts (6 cases)
pins D17: search read path uses gateway.embedQuery() not embed(),
asserted via __setEmbedTransportForTests mock.

* feat(cli): gbrain ze-switch — manual lever for the ZE switch

New gbrain ze-switch CLI with --dry-run, --json, --resume, --force,
--undo, --non-interactive, --confirm-reembed, --ignore-missing-key
flags. Mirrors the upgrade prompt's UX symmetry: --undo presents a
cost-warning before re-embedding back to the prior width.

src/cli.ts: dispatch case + CLI_ONLY entry. ze-switch owns its own
engine lifecycle (mirrors the doctor pattern).

test/ze-switch-cli.test.ts (11 cases): --help, --dry-run, --json,
--non-interactive, --ignore-missing-key, --resume, --undo,
--confirm-reembed. Uses captureExit harness to test process.exit()
paths without breaking the test process.

* feat(doctor): ze_embedding_health + embedding_width_consistency checks

Two new doctor checks (D-A5):

ze_embedding_health: when embedding_model starts with zeroentropyai:,
verify ZEROENTROPY_API_KEY is set (env or config). Paste-ready setup
hint with the signup URL on failure.

embedding_width_consistency: cross-check that the configured
embedding_dimensions matches the actual vector(N) column width on
content_chunks.embedding. Catches the half-applied switch state
(schema migrated but config write crashed) with a paste-ready
gbrain ze-switch --resume hint.

Wired into runDoctor between reranker_health and the existing
sync_freshness checks. Both checks gracefully no-op on non-ZE
embedding configs.

test/doctor-ze-checks.test.ts (8 cases) pins both checks across
happy + missing-key + missing-config + drift paths. Uses withEnv()
helper to clear ZEROENTROPY_API_KEY for the no-key path so tests
are hermetic against contributor env state.

test/e2e/v0_28_5-fix-wave.test.ts + test/openai-compat-multimodal.test.ts:
updated to explicit-configure the gateway when the test depends on
specific dims that diverge from the v0.36.0.0 default (1280d).

* docs: README zero-based rewrite (884 -> 139 lines) + new docs files

Strip 4 months of accreted "New in v0.X.Y" hero blocks and reorganize
around what gbrain does today. 33 H2s -> 8. The Commands section
(136 lines duplicating gbrain --help) moved out; the 6-table skills
enumeration collapsed to a one-paragraph capability description with
a link to skills/RESOLVER.md.

Hero retains load-bearing facts: OpenClaw + Hermes credit, production
numbers (17,888 pages / 4,383 people / 723 companies), BrainBench
numbers (P@5 49.1% / R@5 97.9% / +31.4 lift), ZE comparison numbers,
30-min install claim. Adds one paragraph announcing the v0.36.0.0 ZE
default with the explicit gbrain config set escape for OpenAI/Voyage
users.

New files:
- docs/INSTALL.md: every install path consolidated (agent platform,
  CLI standalone, MCP server). Thin-client mode covered.
- docs/architecture/RETRIEVAL.md: why the hybrid + graph stack works.
  BrainBench numbers, why each strategy alone fails, the source-aware
  ranking + intent classification + multi-query expansion story.
- docs/ethos/ORIGIN.md: origin story lifted from the old README so
  the front door stays factual + concrete.

test/readme-hero-anchors.test.ts (5 cases) is the D9 regression
guard. Five load-bearing strings: OpenClaw, Hermes, ZE,
production-numbers regex, P@5/R@5. Light anchors that let voice/
structure evolve but block accidental loss of headline facts.

scripts/check-test-real-names.sh: allowlist entries for OpenClaw +
Hermes literals in the anchor test (it explicitly asserts those
strings appear in README).

* chore: bump version and changelog (v0.36.0.0)

ZeroEntropy as the new default for embedding (zembed-1 at 1280d via
Matryoshka) and reranker (zerank-2 cross-encoder, on by default in
balanced mode bundle). README zero-based rewrite (884 -> 139 lines).
3 new docs files. Two new doctor checks. New gbrain ze-switch CLI
with --undo for symmetric reversibility.

skills/migrations/v0.36.0.0.md tells the agent how to surface the
retrieval-upgrade prompt post-upgrade.

llms-full.txt regenerated via bun run build:llms.

* fix(docs): scrub Wintermute from RETRIEVAL.md per privacy rule

* chore: rebump version 0.36.0.0 → 0.36.2.0 (queue collision)

Three open PRs were claiming v0.36.0.0 (#1130 skillpack, #1139
hindsight, #1136 this PR). Ship-aware queue allocator says this
branch lands at v0.36.2.0.

Trio audit:
  VERSION       0.36.2.0
  package.json  0.36.2.0
  CHANGELOG     ## [0.36.2.0] - 2026-05-17

Updates: VERSION, package.json, CHANGELOG header + body refs,
README "New default in v0.36.2.0" announcement + credit line,
skills/migrations/v0.36.0.0.md renamed to v0.36.2.0.md with
frontmatter + body refs updated. llms-full.txt regenerated.

* fix(test): pin gateway dim=1536 in cross-file-stateful PGLite tests

CI shard 1 reported 10 failures across `query-cache.test.ts` (6) and
`consolidate-valid-until.test.ts` (4). Both files hardcode 1536-dim
vectors but rely on `PGLiteEngine.initSchema()` to size
`vector(__EMBEDDING_DIMS__)` at the right width.

Root cause: v0.36.2.0 flipped DEFAULT_EMBEDDING_DIMENSIONS from 1536
to 1280 (ZE Matryoshka step). The gateway module is process-singleton;
when ANOTHER test file in the same shard's bun-test process configures
the gateway before us, `pglite-engine.ts:216` reads
`getEmbeddingDimensions() === 1280` and sizes the schema columns at
vector(1280). The hardcoded 1536-dim INSERTs then fail with
"expected 1280 dimensions, not 1536".

Locally these tests pass in isolation because the gateway falls back
through the try/catch at pglite-engine.ts:218 (1536 default). CI runs
multiple test files in one process, so cross-file state poisons the
schema width.

Fix: explicit `resetGateway()` + `configureGateway({embedding_dimensions:
1536, ...})` at the top of `beforeAll`, plus `resetGateway()` in
`afterAll`. Pins the schema width regardless of cross-file state.

488e4824e8 v0.34.1.0 fix(mcp): MCP fix wave — source-isolation P0 + PKCE DCR + federated_read + 3 more (#996)
* fix(mcp): skip stdin EOF handlers when MCP_STDIO=1

OpenClaw's bundle-mcp gateway and similar wrappers pipe the JSON-RPC
handshake on stdin then close their stdin half. Pre-fix, both stdin
'end' and 'close' listeners (server.ts:65-66 and serve.ts:204-206)
treated this as a permanent disconnect and shut the server down before
the first tool call arrived.

Guard both sites with `process.env.MCP_STDIO !== '1'`. Signal handlers
(SIGTERM/SIGINT/SIGHUP), transport.onclose, and the parent-process
watchdog still cover legitimate shutdown paths. The serve.ts site
threads the env read through an injectable `mcpStdio?: boolean` on
ServeOptions so tests stay isolated (no process.env mutation per
scripts/check-test-isolation.sh R1).

Tests: 3 new cases in test/serve-stdio-lifecycle.test.ts pin the
guard's invariants — mcpStdio=true must NOT trigger shutdown on stdin
EOF, signals must still drive shutdown with mcpStdio=true, and
mcpStdio=false (default) preserves existing CLI behavior. 25/25 pass.

* fix(oauth): honor token_endpoint_auth_method=none for PKCE public clients

RFC 7591 §3.2.1: when a DCR client declares
token_endpoint_auth_method="none" (PKCE-only public clients like Claude
Code, Cursor), the authorization server MUST NOT issue a client_secret.
Pre-fix, registerClient unconditionally minted a secret, and the MCP
SDK's clientAuth middleware then rejected valid public-client flows on
/token because it expected client.client_secret to match.

Three changes to src/core/oauth-provider.ts:registerClient:

  - Gate clientSecret generation on isPublicClient = (auth_method === 'none').
    Public clients store client_secret_hash = NULL.
  - Omit client_secret from the response payload for public clients.
    Confidential clients (default client_secret_post and explicit
    client_secret_basic) keep their existing one-time-reveal shape.
  - Normalize NULL secret_hash to JS undefined in getClient so SDK
    middleware (which checks client.client_secret === undefined, not
    === null) correctly identifies public clients and skips the
    secret-comparison branch on /token.

Schema is already permissive (client_secret_hash TEXT, no NOT NULL on
both src/schema.sql and src/core/pglite-schema.ts) — no migration
needed.

Tests: 5 new cases in test/oauth.test.ts pin:
  - public client → no client_secret in response (#11 from plan)
  - default auth_method → secret unchanged (regression guard)
  - explicit client_secret_post → secret unchanged
  - getClient NULL→undefined normalization
  - PKCE full /authorize → /token end-to-end with no secret (#15 from plan)

69/69 oauth.test.ts cases pass. typecheck clean.

* feat(serve-http): --bind HOST, default to loopback (127.0.0.1)

Adds `gbrain serve --http --bind <interface>` to control which network
interface the HTTP MCP server listens on. Default flipped from
`0.0.0.0` (pre-v0.34) to `127.0.0.1` (v0.34.0+).

Why the flip: gbrain's primary use case is a personal-knowledge brain on
a laptop. The previous default exposed brains on every interface — one
accidental `--http` invocation away from publishing the brain to a LAN.
Server operators who need remote access pass `--bind 0.0.0.0` (or a
specific interface). Codex's outside-voice on the original PR #864
correctly flagged that the additive flag wasn't actually the fix; the
default needed to change for the safety claim to hold.

If `--public-url` is set but `--bind` is unset, runServeHttp prints a
loud stderr WARN at startup recommending `--bind 0.0.0.0`. Declaring a
public URL while quietly binding loopback is almost always a
misconfiguration; we want the operator to see it on first start, not
silently fail remote requests.

Startup banner now includes a `Bind:` row so the listening interface is
visible alongside Port / Engine / Issuer.

Origin: PR #864, extended with D11 (default flip) per /plan-eng-review
codex outside-voice review.

* fix(mcp): seal source-isolation leak on read path (P0)

Pre-fix, an authenticated OAuth MCP client scoped to source-A could
enumerate source-B pages via six read-side ops: search, query (text
AND image paths), list_pages, traverse_graph, and find_experts. The
v0.31.8 source-scoping pattern shipped through dispatch.ts but the op
handlers never threaded ctx.sourceId into their engine calls, and
hybridSearch.ts:223's explicit SearchOpts rebuild dropped sourceId
even when callers passed it.

Sealing the leak:

  - src/core/operations.ts adds sourceScopeOpts(ctx), the canonical
    precedence ladder: ctx.auth.allowedSources (federated) wins over
    ctx.sourceId (scalar) wins over nothing. Threaded into all 5
    read-side op handlers + the query-image-path searchVector call
    (the 6th leak surface codex caught in plan review).

  - src/core/search/hybrid.ts:223 now threads sourceId + sourceIds
    fields through the inner SearchOpts rebuild. The explicit pick
    shape is preserved (HNSW inner-CTE ordering depends on it) but
    extended.

  - src/core/types.ts adds sourceIds?: string[] to SearchOpts +
    PageFilters (D9: federated read needs array-shaped engine filter
    or fan-out; array wins for hot retrieval).

  - src/core/operations.ts AuthInfo gains sourceId + allowedSources
    (D2: identity surface symmetric with the federated_read column
    #876 will add).

  - Both engines now apply WHERE source_id = $N (scalar) or = ANY($N::text[])
    (array) at the SQL layer for searchKeyword, searchKeywordChunks,
    searchVector, listPages, traverseGraph, traversePaths. Array form
    wins when both are set. The searchVector filter pushes into the
    inner HNSW CTE (codex flagged this placement during plan review).

  - traverseGraph + traversePaths signatures gain opts.sourceId +
    opts.sourceIds; engine.ts interface updated.

  - findExperts (the whoknows op, D3 5th leak surface) accepts
    sourceId + sourceIds and threads them into its internal
    hybridSearch call. PR #861 was authored before v0.33 shipped so
    this op wasn't covered in the original PR.

Auth wiring:

  - GBrainOAuthProvider.verifyAccessToken populates AuthInfo.sourceId
    from oauth_clients.source_id. JOIN guarded by isUndefinedColumnError
    so pre-v55 brains degrade to legacy projection rather than refusing
    every token verification.

  - GBrainOAuthProvider.registerClientManual gains a sourceId
    parameter (defaults to 'default'). DCR registerClient also sets
    source_id='default' on the inserted row.

  - serve-http.ts:929 cleanup: AuthInfo.sourceId is now a real typed
    field. The cast + GBRAIN_SOURCE env fallback chain is gone (D13).
    Legacy bearer tokens default to 'default' source in
    verifyAccessToken.

  - http-transport.ts (legacy access_tokens path) threads
    sourceId='default' through DispatchOpts so v0.22.7 callers stay
    source-scoped.

  - auth.ts CLI adds --source flag to gbrain auth register-client.

Migration v55 (D10 + D13):

  - ALTER TABLE oauth_clients ADD COLUMN source_id TEXT (nullable).
  - Backfill UPDATE source_id = 'default' WHERE source_id IS NULL —
    preserves v0.33 effective behavior verbatim for legacy clients.
  - ADD CONSTRAINT FK ... REFERENCES sources(id) ON DELETE SET NULL,
    wrapped in DO block so re-runs against fresh-install brains (where
    the FK already lives inline in SCHEMA_SQL) no-op cleanly.
  - CREATE INDEX idx_oauth_clients_source_id WHERE source_id IS NOT NULL
    for the verifyAccessToken JOIN.
  - GBRAIN_ACCEPT_SILENT_WIDEN env-flag wired through the runner via
    SET LOCAL gbrain.accept_silent_widen — reserved for future migrations
    that hit the silent-widen footgun codex flagged. This migration
    doesn't need it (column is brand new; no pre-existing stale values
    possible by definition).
  - src/core/pglite-schema.ts + src/schema.sql include the column +
    FK + index inline for fresh installs.

Tests: new test/e2e/source-isolation-pglite.test.ts with 13 regression
cases — one per leak surface (search/list_pages/traverse/etc.) plus
explicit AuthInfo.sourceId and AuthInfo.allowedSources op-handler
threading checks. Full unit suite: 6034 pass / 0 fail. PGLite
initSchema time dropped from 2.4s to 850ms after consolidating v55's
DO blocks (multiple DO blocks were slow on PGLite; one DO block for
the FK install only is fine).

* feat(gateway): multimodal embedding for openai-compatible providers

Pre-fix, embedMultimodal hardcoded a recipe.id === 'voyage' branch and
threw AIConfigError for every other recipe. Multimodal-capable providers
fronted by LiteLLM (or any openai-compatible proxy) were unreachable
even when the operator had wired up the model.

The fix:

  - src/core/ai/gateway.ts adds embedMultimodalOpenAICompat() that
    POSTs to the standard /embeddings endpoint with content arrays
    carrying image_url entries. Routing comes from the existing
    recipe.implementation switch — Voyage stays on its own
    /multimodalembeddings path; every other openai-compatible recipe
    flows through the new helper.

  - src/core/ai/recipes/litellm-proxy.ts declares
    supports_multimodal: true so embedMultimodal accepts the recipe.
    No multimodal_models allow-list: LiteLLM is a passthrough proxy
    and the user owns model-id selection; provider rejection (400 from
    upstream) is the right enforcement layer there. Voyage's static
    allow-list shape stays unchanged (its 12 models share
    supports_multimodal but only one is multimodal-capable).

  - D12 runtime dimension validation: the new helper checks the
    returned vector length against the recipe's declared default_dims
    (preferred) or the brain's embedding_dimensions config. Mismatch
    throws AIConfigError with model id + observed + expected so the
    operator can swap models or rebuild the column. Pre-fix, a
    wrong-dim response would surface as a cryptic pgvector
    "vector dimension mismatch" at INSERT time.

  - Auth resolution routes through the existing defaultResolveAuth
    helper so optional-auth recipes (LiteLLM proxy with no
    LITELLM_API_KEY) and required-auth recipes both share one code
    path. Optional-auth sends "Authorization: Bearer unauthenticated"
    which servers like Ollama / llama-server ignore but the SDK
    contract requires.

Tests: 11 new cases in test/openai-compat-multimodal.test.ts cover
happy-path, multi-input batching, unauthenticated proxy, D12 dim
mismatch + default-dim fallback, 401 / 400 / malformed-JSON / non-array
error paths, and an explicit Voyage-regression test pinning that the
new openai-compat route doesn't accidentally hijack the Voyage path.
All 41 multimodal-related tests pass (existing voyage suite + new).
typecheck clean.

Origin: PR #875 + plan-eng-review D12 (runtime dim validation).

* feat(oauth): federated_read read scope (#876)

Pre-fix, OAuth clients had a single source-scope axis (source_id, added
in v55). A client could either write+read one source OR be a super-reader
across all sources (via NULL source_id). There was no middle ground —
WeCare-style L3 dept clients that need to write to dept-x but read
dept-x + parent canon + shared canon had no expression.

#876 adds federated_read TEXT[] as an orthogonal read-scope axis. source_id
is the WRITE authority; federated_read is the READ authority. They default
to matching values (read scope == write scope, the pre-v0.34 default)
when a client is registered without an explicit federated read list.

Migrations v56-v60 (six new migrations on top of v55):

  - v56: ALTER TABLE ... ADD COLUMN federated_read TEXT[] NOT NULL DEFAULT '{}'.
  - v57 (F5): explicit CASE backfill so source_id IS NULL → '{}' (not an
    array containing NULL — codex caught this ambiguity during plan review).
  - v58: post-backfill validation. Fails loud if any row's source_id isn't
    in its federated_read array, pointing at a logic bug in v57 if fired.
  - v59: flip the source_id FK from ON DELETE SET NULL to ON DELETE
    RESTRICT now that federated_read provides the alternative scope-loss
    path. Pre-flip, deleting a source could silently widen any oauth_client
    to super-reader; post-flip, source delete is refused if any client
    references it (operator must revoke/re-scope first).
  - v60: GIN index on federated_read for array-containment queries.

Auth wiring:

  - GBrainOAuthProvider.verifyAccessToken JOINs c.federated_read and
    populates AuthInfo.allowedSources. Pre-v56 / pre-v55 brains degrade
    via the existing isUndefinedColumnError fallback chain.
  - registerClientManual gains a federatedRead?: string[] parameter
    (defaults to [sourceId]).
  - DCR registerClient sets source_id='default' + federated_read=['default']
    on the inserted row.
  - auth.ts CLI adds --federated-read SRC1,SRC2,... flag. The
    register-client output now prints "Federated reads:" so operators
    confirm the scope they set.

Engines consume the federated array through the SearchOpts.sourceIds /
PageFilters.sourceIds field that #861 added (no engine changes here — the
plumbing was D9). sourceScopeOpts in operations.ts already prefers the
auth.allowedSources array over scalar ctx.sourceId when set.

Test seam:
  - test/book-mirror.test.ts now spawns the CLI with GBRAIN_HOME pointed
    at a tempdir so the test isn't sensitive to the developer's local
    ~/.gbrain/config.json. Pre-fix the test could silently inherit a real
    Postgres connection and hang past the default 5s test timeout. Fresh
    GBRAIN_HOME → "No brain configured" → exit 1 in <1s.
  - test/e2e/source-isolation-pglite.test.ts gains one more regression
    case: AuthInfo.allowedSources = [] (explicit empty) MUST NOT widen
    scope to "all sources" — the silent-widen footgun precedence ladder.
  - test/openai-compat-multimodal.test.ts is part of the wave's commits
    via the migrate.ts changes that bump the schema chain. typecheck-only
    fix on a captured-auth type was already in #875's tree.

6045 unit tests pass / 0 fail. typecheck clean. PGLite initSchema runs
v55-v60 in ~786ms total (within the test-harness budget for tests using
the canonical beforeAll engine pattern).

Origin: PR #876 + plan-eng-review F5 (CASE backfill).

* chore: bump v0.34.0.0 → v0.34.1.0

Renumbering the MCP fix wave from v0.34.0.0 to v0.34.1.0 so the
release slot lands between master's v0.33.2.1 and the next minor.

Touches every release-artifact mention:
- VERSION: 0.34.0.0 → 0.34.1.0
- package.json: same
- CHANGELOG.md header + "To take advantage" block
- CLAUDE.md key-files annotations (8 entries that document this wave)
- llms-full.txt (regen from CLAUDE.md)
- README.md / SECURITY.md / docs/architecture/topologies.md / docs/mcp/DEPLOY.md
- Wave code-comment markers ("// v0.34.0 (#NNN):" → "// v0.34.1 (#NNN):")

Test files renamed alongside since they were committed with the wave.

Commit subjects on the original 6 PR commits + the v0.34.0.0 bump
commit (4f533c726b47db7e) intentionally NOT rewritten — those are
history. `git log` finds the implementation by message subject, not by
version tag.

6275 unit tests pass, typecheck clean, migration chain v58-v63 unchanged.

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.

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.

8392d434a9 v0.29.2 feat: thin-client mode (gbrain init --mcp-only + gbrain remote ping/doctor + topologies) (#732)
* feat(config): add remote_mcp field + isThinClient() helper

Adds a top-level optional remote_mcp config block to GBrainConfig
(issuer_url, mcp_url, oauth_client_id, oauth_client_secret) for
thin-client installs that consume a remote `gbrain serve --http` over
MCP instead of running a local engine.

isThinClient(config) returns true when remote_mcp is set; used by the
CLI dispatch guard, doctor branch, and init re-run guard. The engine
field stays as today (postgres|pglite); thin-client mode is a separate
config field, NOT an engine kind extension (codex outside-voice review
flagged the engine='remote' extension as overreach).

GBRAIN_REMOTE_CLIENT_SECRET env var overrides the config-file value at
load time so the secret can stay out of disk for headless agents.

Foundation commit for multi-topology v1; no behavior change yet.

* feat(probe): outbound OAuth + MCP smoke probes

Adds three pure async functions over the standard fetch API:
  - discoverOAuth(issuerUrl): GET /.well-known/oauth-authorization-server
  - mintClientCredentialsToken(tokenEndpoint, id, secret): POST /token
  - smokeTestMcp(mcpUrl, accessToken): POST /mcp initialize

Discriminated 'ok=true' / 'ok=false + reason' return shapes so callers
render error messages consistently. No SDK dependency to keep init's
setup-flow scope tight; Lane B's mcp-client.ts will pull in the
official @modelcontextprotocol/sdk Client for full session semantics.

Used by both 'gbrain init --mcp-only' (Lane A's setup smoke) and
runRemoteDoctor (Lane A's thin-client doctor checks).

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

* feat(init): --mcp-only branch + re-run guard

Adds 'gbrain init --mcp-only' for thin-client setup. Required flags
(or env vars):
  --issuer-url     OAuth root (e.g. https://host:3001)
  --mcp-url        MCP tool dispatch path (e.g. https://host:3001/mcp)
  --oauth-client-id, --oauth-client-secret

Pre-flight runs three smoke probes (discovery, token round-trip, MCP
initialize) BEFORE writing the config — fail-fast on bad URL beats
fail-late on bad credentials. On success, writes ~/.gbrain/config.json
with remote_mcp set and NO local DB created.

Re-run guard (A8): when ~/.gbrain/config.json already has remote_mcp,
'gbrain init' (any flag set) refuses without --force. Catches the
scripted-setup-loop friction from the user-reported scenario where
re-running setup-gbrain on a thin-client machine kept trying to
re-create a local DB.

Two URLs in config (issuer + mcp) instead of one because OAuth
discovery + /token live at the issuer root while tool dispatch is at
/mcp — they compose from a common base in practice but reverse-proxy
setups need them explicit (codex review #2).

Tests: 15 cases covering happy path, env-var-supplied secret stays
out of disk, all four required-flag missing-error paths, three
smoke-failure paths, network-unreachable path, and the four re-run
guard variants (default/--pglite/--mcp-only without --force / with
--force). Uses async Bun.spawn (NOT execFileSync) — sync exec
deadlocks against in-process HTTP fixtures because the parent's
event loop can't accept connections while sync-blocked on a child.

* feat(doctor): runRemoteDoctor for thin-client mode

Replaces every DB-bound check from runDoctor() with a tighter set
scoped to 'is the remote MCP we configured actually reachable?'.
Five checks:
  - config_integrity (URL fields well-formed)
  - oauth_credentials (secret resolvable from env or config file)
  - oauth_discovery (GET /.well-known/oauth-authorization-server)
  - oauth_token (POST /token client_credentials)
  - mcp_smoke (POST /mcp initialize)

Output shape matches the local doctor's Check surface so JSON
consumers can union the two without conditional logic. schema_version
is 2 (matches local doctor).

collectRemoteDoctorReport() is the pure data collector;
runRemoteDoctor() is the print/exit wrapper. Tests pin the data
collector so we don't have to intercept stdout / process.exit.

Tests: 12 cases over a tiny in-process HTTP fixture covering happy
path, every probe failure mode (404/parse/auth/network/server-error),
malformed-URL config integrity, missing-secret short-circuit, and
the env-var-overrides-config-file secret resolution. withEnv() helper
used for env mutations to satisfy the test-isolation lint.

Module is added but not yet wired into the CLI doctor branch; the
wiring lands in the next commit (cli dispatch guard + doctor routing).

* feat(cli): thin-client dispatch guard + doctor routing

Adds a single canonical refusal at the top of handleCliOnly() for the
9 DB-bound commands when ~/.gbrain/config.json has remote_mcp set:
  sync, embed, extract, migrate, apply-migrations, repair-jsonb,
  orphans, integrity, serve

Single dispatch check (not 9 sprinkled assertLocalEngine calls per
codex review #1) — avoids the blast radius of letting commands enter
connectEngine before the check fires. Refused commands exit 1 with a
canonical error naming the remote mcp_url.

doctor branch routes to runRemoteDoctor when isThinClient(config)
returns true; falls through to the existing local-doctor flow
otherwise. Wires the module added in the previous commit into the
user-facing CLI surface.

Safe commands (init, auth, --version, --help, etc.) still work in
thin-client mode and are NOT in the refused set.

Tests: 14 cases — 9 refused commands × 1 each, 2 safe commands, 1
doctor-routing assertion (fingerprints the thin-client output by
'mode:"thin-client"' in JSON), 2 regression tests asserting local
config still passes through normally.

* docs(topologies): multi-topology architecture guide + setup skill Phase A.5

New docs/architecture/topologies.md covering three deployment shapes:
  1. Single brain (today's default)
  2. Cross-machine thin client (consume a remote brain over MCP)
  3. Split-engine per-worktree (Conductor users with per-worktree
     code engines + shared remote artifacts brain)

Each topology gets an ASCII diagram, when-it-fits guidance, and
concrete setup recipes. Topology 3's alias-level routing footgun
(wrong alias = silent wrong-brain writes) is called out explicitly
per codex review #6.

Topology 3 needs zero gbrain code changes — GBRAIN_HOME already
overrides ~/.gbrain and 'gbrain serve --http --port N' already runs
on any port. gstack composes these primitives on its side.

skills/setup/SKILL.md gets Phase A.5 BEFORE the local-engine phases.
Asks the user which topology fits, walks thin-client setup through
'gbrain init --mcp-only', skips Phases B/C/C.5/H entirely for thin
clients (host's autopilot handles sync/extract/embed).

README.md gets a one-line link to the topology doc from the
Architecture section.

llms-full.txt regenerated to include the new doc.

* test(e2e): thin-client end-to-end skeleton

Spins up 'gbrain serve --http' against real Postgres, registers a
client with read,write,admin scope, runs 'gbrain init --mcp-only'
from a separate tempdir GBRAIN_HOME, exercises the canonical
thin-client flows:

  - init --mcp-only succeeds against the live host
  - doctor reports mode: thin-client + all checks green
  - sync is refused with the canonical thin-client error
  - re-running init refuses without --force

Tier B flows (gbrain remote ping / doctor) will be added alongside
their Lane B implementation. Skips when DATABASE_URL unset (matches
the e2e gate convention used across the suite).

Async Bun.spawn (NOT execFileSync) so the test event loop stays
responsive — execFileSync deadlocks against in-process HTTP fixtures
because the parent's event loop can't accept connections while
sync-blocked on a child process.

* feat(doctor): doctorReportRemote core for thin-client + run_doctor op

Adds three new exports to src/commands/doctor.ts that the run_doctor MCP
op + gbrain remote doctor CLI both consume:

  - DoctorReport interface       schema_version=2 stable shape
  - computeDoctorReport(checks)  status + health_score math
  - doctorReportRemote(engine)   focused 5-check thin-client surface

doctorReportRemote runs:
  1. connection      (engine reachable + page count via getStats)
  2. schema_version  (engine.getConfig('version') vs LATEST_VERSION)
  3. brain_score     (the 5-component composite)
  4. sync_failures   (file-plane JSONL count from gbrainPath('sync-failures.jsonl'))
  5. queue_health    (Postgres-only: stalled active jobs > 1h)

Engine-agnostic: works on both Postgres and PGLite via engine.executeRaw +
engine.getConfig + engine.getHealth — no reliance on db.getConnection()
which is Postgres-only.

Deliberately a focused subset of the local doctor surface, NOT a full
mirror. Generalizing to lint/integrity/orphans is filed as follow-up
pending demand. Local doctor (runDoctor) is unchanged; operators on the
host machine still get the full check set.

schema_version=2 matches the local doctor's --json output schema, so JSON
consumers can union the two without conditional logic.

Tests: 11 unit cases against PGLite covering the 5-check happy path,
schema version reporting (latest), PGLite-specific queue_health
informational message, and the score+status math via computeDoctorReport.

* feat(mcp-client): outbound HTTP MCP client over @modelcontextprotocol/sdk

New src/core/mcp-client.ts wraps the official SDK's Client +
StreamableHTTPClientTransport with OAuth client_credentials minting,
in-process token caching with expires_at, and refresh-on-401 retry.

Public surface:
  - callRemoteTool(config, toolName, args)   tool call w/ auto-refresh
  - unpackToolResult(res)                    parse content[0].text JSON
  - RemoteMcpError                           discriminated by `reason`

Token cache: module-level Map keyed by mcp_url. CLI processes are
short-lived; the cache amortizes when one invocation makes multiple
calls (gbrain remote ping submits then polls). Persisting to disk would
be a credential-on-disk surface for marginal benefit since /token
round-trip is sub-100ms.

401 retry: ONLY for mid-session token rotation (initial good token →
stale → 401). If the FIRST mint fails auth, surface immediately as
RemoteMcpError(auth) — retry won't help when credentials are wrong from
the start. If a fresh-mint-after-401 still 401s, surface as
RemoteMcpError(auth_after_refresh) which the CLI renders with a hint
pointing the operator at gbrain auth register-client.

Used by gbrain remote ping (submit_job + get_job poll) and gbrain
remote doctor (run_doctor). Test-only _clearMcpClientTokenCache export
for fixture isolation.

Tests: 13 unit cases over an in-process HTTP fixture mimicking gbrain
serve --http (OAuth discovery + /token + /mcp JSON-RPC handshake).
Covers happy path, token cache reuse + force-refresh, args passthrough,
config-error paths (no remote_mcp / no secret), token mint 401, network
unreachable, tool isError envelope, and unpackToolResult parse failures.

* feat(operations): add run_doctor MCP op (admin scope, HTTP-reachable)

New op in src/core/operations.ts wraps doctorReportRemote() and returns
the structured DoctorReport JSON over MCP.

  scope:     'admin'       (system-state read; not for routine consumers)
  localOnly: false         (reachable over HTTP)
  mutating:  false         (safe to call repeatedly)
  params:    {}            (no caller arguments needed)

First read-only diagnostic op exposed over HTTP MCP. Used by gbrain
remote doctor — the matching client-side renderer lives in
src/commands/remote.ts.

Precedent: doctor only. Generalizing run_lint / run_integrity /
run_orphans to MCP is filed as follow-up work pending demand. Local
doctor stays unchanged; this op is the operator-friendly subset for
remote callers.

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

* feat(remote): gbrain remote ping + gbrain remote doctor

Two thin-client convenience commands that round-trip through the host's
HTTP MCP endpoint:

  - gbrain remote ping     submit_job(autopilot-cycle) → poll get_job →
                           exit when terminal. The "I just wrote markdown,
                           tell the host to re-index" affordance.
  - gbrain remote doctor   run_doctor MCP op → render the host's
                           DoctorReport → exit 0/1 based on status.

Both require a thin-client install (~/.gbrain/config.json with
remote_mcp). Local installs get a clear error pointing at the local
equivalents.

Polling backoff (ping): 1s × 30s, then 5s × 5min, then 10s. Default cap
15min, configurable via `--timeout`. Without backoff, a 5-min cycle
would burn 300 round-trips against the host's rate limiter.

Payload uses `data: {phases: [...]}`, NOT `params:` — the submit_job op
shape takes `data`. Codex review #8 catch.

NO `repo` arg passed to autopilot-cycle — uses the server's configured
brain repo. This sidesteps TODO #1144 (sync_brain repo-path validation
for caller-controlled paths) entirely.

src/cli.ts wires the `remote` subcommand into CLI_ONLY + the dispatch.
Help (`gbrain remote --help`) and unknown-subcommand handling included.

* test(e2e): thin-client Tier B + scope-mismatch regression

Extends the existing test/e2e/thin-client.test.ts with three new cases:

  1. gbrain remote doctor returns the host's DoctorReport — pins the
     run_doctor MCP op round-trip. Asserts schema_version=2, all 5
     check names present, connection + schema_version ok against a
     fresh host.
  2. gbrain remote ping triggers autopilot-cycle and returns terminal
     state — pins the submit_job → poll → terminal wire path. Accepts
     any terminal state (success / failed / dead / cancelled / timeout)
     because autopilot on an empty no-repo brain may fail-fast in the
     sync phase. What this test pins is the JSON shape (job_id present,
     state populated), NOT cycle success on a no-repo fixture.
  3. read+write client cannot call run_doctor — codex review #7
     regression guard. Registers a separate client with
     `--scopes "read write"` (no admin), runs `gbrain remote doctor`
     against it, asserts exit 1 with auth/auth_after_refresh/tool_error
     reason. Keeps the verification flow honest: the canonical setup
     MUST require admin scope.

`gbrain auth register-client` doesn't have --json, so the test parses
the human output for "Client ID:" and "Client Secret:" lines via a
helper.

Test-level timeout bumped 60s → 120s for the ping wait + auth/init
overhead.

* chore: bump version and changelog (v0.29.2)

v0.29.2 ships thin-client mode: gbrain init --mcp-only, gbrain remote
ping/doctor, run_doctor MCP op, and the docs/architecture/topologies.md

3c032d79ec v0.26.0 feat: GBrain — MCP Keys OAuth 2.1 + HTTP server + admin dashboard (#358)
* feat: OAuth 2.1 schema tables + shared token utilities

Add oauth_clients, oauth_tokens, oauth_codes tables to both PGLite and
Postgres schemas. Migration v5 creates tables for existing databases.
PGLite now includes auth infrastructure (access_tokens, mcp_request_log,
OAuth tables) because `serve --http` makes it network-accessible.

Extract hashToken() and generateToken() to src/core/utils.ts for DRY
reuse across auth.ts and oauth-provider.ts.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: GBrainOAuthProvider — MCP SDK OAuthServerProvider implementation

Implements OAuthServerProvider backed by raw SQL (PGLite or Postgres).
Supports client credentials, authorization code with PKCE, token refresh
with rotation, revocation, and legacy access_tokens fallback.

Key decisions from eng review:
- Uses raw SQL connection, not BrainEngine (OAuth is infrastructure)
- All tokens/secrets SHA-256 hashed before storage
- Legacy tokens grandfathered as read+write+admin
- sweepExpiredTokens() wrapped in try/catch (non-blocking startup)
- Client credentials: no refresh token per RFC 6749 4.4.3

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: scope + localOnly annotations on all 30 operations

Add AuthInfo, scope ('read'|'write'|'admin'), and localOnly fields to
Operation interface. Per-operation audit:
- 14 read ops, 9 write ops, 2 admin ops, 4 admin+localOnly ops
- sync_brain, file_upload, file_list, file_url: admin + localOnly
- Scope enforcement happens in serve-http.ts before handler dispatch

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: HTTP MCP server with OAuth 2.1 + 27 OAuth tests

gbrain serve --http starts Express 5 server with:
- MCP SDK mcpAuthRouter (authorize, token, register, revoke endpoints)
- Custom client_credentials handler (SDK doesn't support CC grant)
- Bearer auth + scope enforcement on /mcp tool calls
- Admin dashboard auth via HTTP-only cookie + bootstrap token
- SSE live activity feed at /admin/events
- DCR default OFF (--enable-dcr to enable)
- Rate limiting on /token (50/15min)
- localOnly operations excluded from HTTP

CLI: gbrain serve --http [--port 3131] [--token-ttl 3600] [--enable-dcr]

Dependencies: express@5.2.1, express-rate-limit@7.5.1, cors@2.8.6
SDK pinned to exact 1.29.0 (was ^1.0.0)

27 new tests covering OAuth provider, scope enforcement, auth code flow,
refresh rotation, token revocation, legacy fallback, and sweep.

* feat: React admin dashboard — 7 screens, dark theme, Krug-designed

Admin SPA at /admin with client-side routing (#login, #dashboard,
#agents, #log). Built with Vite + React, served from admin/dist/.

Screens:
- Login: one field, one button, zero happy talk
- Dashboard: metrics bar, SSE live activity feed, token health panel
- Agents: table with scopes/badges, + Register Agent button
- Register: modal form (name, scopes), 3 mindless choices
- Credentials: full-screen modal, copy buttons, download JSON, warning
- Request Log: paginated table (50/page), time-relative timestamps
- Agent Detail: slide-out drawer, config export tabs (Perplexity/Claude/JSON)

Design tokens: #0a0a0f bg, Inter + JetBrains Mono, 4-32px spacing.
Build: bun run build:admin (Vite, 65KB gzipped).
Admin API: /admin/api/register-client endpoint for dashboard registration.
SPA serving: Express static + index.html fallback for client-side routing.

* docs: update project documentation for v1.0.0.0

Sync README, CLAUDE.md, and docs/mcp/ with the OAuth 2.1 + HTTP server
+ admin dashboard surface that shipped in v1.0.0.0.

- README.md: new "Remote MCP with OAuth 2.1" section covering
  gbrain serve --http, admin dashboard, scoped operations, legacy
  bearer fallback; add serve --http + auth notes to the commands
  reference.
- CLAUDE.md: add src/commands/serve-http.ts, src/core/oauth-provider.ts,
  admin/ directory as key files; document scope + localOnly additions
  to Operation contract; add oauth.test.ts (27 cases) to the test list;
  add v1.0.0 key-commands section clarifying that OAuth client
  registration is via the /admin dashboard or SDK (no CLI subcommand).
- docs/mcp/DEPLOY.md: promote --http as the recommended remote path,
  add OAuth 2.1 Setup section, list ChatGPT in supported clients,
  remove the "not yet implemented" footer.
- docs/mcp/CHATGPT.md (new): unblocks the P0 TODO. Full ChatGPT
  connector setup via OAuth 2.1 + PKCE.

* feat: wire gbrain auth subcommand with OAuth register-client

Previously auth.ts was a standalone script invoked via
`bun run src/commands/auth.ts`. CHANGELOG and README documented
`gbrain auth ...` commands that didn't actually work.

- Export `runAuth(args)` from auth.ts (keeps standalone entry intact
  via `import.meta.url === file://${process.argv[1]}` check)
- Add `auth` to CLI_ONLY + dispatch in handleCliOnly
- New subcommand `gbrain auth register-client <name> [--grant-types]
  [--scopes]` wraps GBrainOAuthProvider.registerClientManual
- Lazy DB check: only subcommands that need DATABASE_URL error out

Now the documented CLI flow works end to end:
  gbrain auth register-client perplexity --grant-types client_credentials --scopes "read write"
  gbrain serve --http --port 3131

* docs: reflect wired gbrain auth register-client CLI

After /ship, the doc subagent wrote docs assuming `gbrain auth
register-client` did not exist (it said so explicitly in CLAUDE.md:184).
A follow-up commit (c4a86ce) wired it into src/cli.ts + src/commands/auth.ts.
These docs were now contradicting reality.

- CLAUDE.md: removed "There is no gbrain auth register-client CLI
  subcommand" claim, documented the three registration paths
  (CLI / dashboard / SDK).
- README.md: replaced `bun run src/commands/auth.ts` hint with
  `gbrain auth create|list|revoke|test` and `gbrain auth register-client`.
- docs/mcp/DEPLOY.md: added CLI registration example above the
  programmatic example.
- TODOS.md: moved "ChatGPT MCP support (OAuth 2.1)" P0 item to
  Completed with v1.0.0.0 completion note. Closes the P0 that had been
  blocking the "every AI client" promise since v0.6.

* fix: enable RLS on OAuth tables + loosen v24-exact test assertion

CI Tier 1 (Mechanical) was failing on 4 E2E tests after the v0.18.1 RLS
hardening landed on master (PR #343). Our v25 oauth_infrastructure migration
adds 3 new public tables (oauth_clients, oauth_tokens, oauth_codes) but
didn't enable RLS, so gbrain doctor's new check flagged them and the
"RLS on every public table" assertion failed.

Fixes:
- src/schema.sql: ALTER TABLE ... ENABLE ROW LEVEL SECURITY for the 3 OAuth
  tables inside the existing BYPASSRLS-gated DO block (fresh installs).
- src/core/migrate.ts v25: append a BYPASSRLS-gated DO block after the OAuth
  CREATE TABLE statements (existing installs on upgrade). Mirrors the v24
  rls_backfill gating pattern — RAISE WARNING if the current role lacks
  BYPASSRLS, so migrations don't silently lock the operator out.
- src/core/schema-embedded.ts: regenerated via `bun run build:schema`.
- test/e2e/mechanical.test.ts: one unrelated v24 test asserted the post-
  migration version equals exactly '24'. That breaks when any later
  migration exists (like our v25). Relaxed to `>= 24` since the test's
  intent is "v24 didn't abort the chain", not "v24 is the final version".

Verified locally: 78/78 E2E tests pass against real Postgres 16 + pgvector.

* chore: regenerate llms-full.txt for v1.0.0 docs

CI test/build-llms.test.ts > committed llms.txt + llms-full.txt match
current generator output failed. The committed llms-full.txt was built
before the v1.0.0 doc updates landed (OAuth 2.1 README section, new
docs/mcp/CHATGPT.md, CLAUDE.md serve-http references, etc.), so the
regen-drift guard flagged it.

Ran `bun run build:llms`. llms.txt is unchanged (skinny index still
matches); llms-full.txt picks up 166 net-new lines of bundled content.

* connected-gbrains PR 0 — minimal runtime (mounts, registry, aggregated RESOLVER) (#372)

* feat(mounts): connected-gbrains PR 0 foundation — registry + resolver + CLI

Lays the foundation for connected gbrains (v0.19.0) per the approved plan.
This is PR 0 — minimal runtime for direct-transport, path-mounted brains.

What this slice ships:
- src/core/brain-registry.ts — keyed BrainRegistry with lazy engine init,
  schema-validated mounts.json loader, DuplicateMountPathError (load-bearing
  identity check per Codex finding #9 correction), UnknownBrainError with
  actionable available-id list. Pure: no AsyncLocalStorage, no singleton
  mutation. ~280 LOC.

- src/core/brain-resolver.ts — 6-tier brain-id resolution mirroring
  v0.18.0's source-resolver.ts so agents learn ONE mental model:
    1. --brain <id>     2. GBRAIN_BRAIN_ID env      3. .gbrain-mount dotfile
    4. longest-path match over registered mounts    5. (reserved v2 default)
    6. 'host' fallback
  Orthogonal to --source: --brain picks which DB, --source picks the repo
  within that DB. Corruption-resistant: mounts.json load failures fall
  through to 'host' instead of breaking every CLI invocation.

- src/commands/mounts.ts — `gbrain mounts add|list|remove` (direct transport
  only). Validates on add (path exists on disk, id regex, no dupes). WARNS
  but does not block on same db_url/db_path across ids (teams may
  legitimately alias a remote brain). Password redaction in list output.
  Atomic write via temp+rename. 0600 perms. PR 1 adds pin/sync/enable;
  PR 2 adds --mcp-url + OAuth.

- src/cli.ts — wires `gbrain mounts` into handleCliOnly (no DB required
  for the config-only subcommands).

- test/brain-registry.test.ts (28 cases): schema validation across every
  malformed-input branch, ALS-free resolution, duplicate id + path detection,
  disabled-mount exclusion, UnknownBrainError context.

- test/brain-resolver.test.ts (22 cases): priority order (explicit > env >
  dotfile > path-prefix > fallback), dotfile walk-up, malformed dotfile
  recovery, longest-prefix match, sibling-path false-positive guard,
  loader-failure defense.

- test/mounts-cli.test.ts (17 cases): parseAddArgs surface, redactUrl,
  atomic write, add/list/remove roundtrip via temp HOME.

67 new tests, all green. Typecheck clean. Depends on mcp-key-mgmt (base
branch) for the OAuth/scope annotations that PR 2 will leverage.

Next in this branch: PR 0 still needs (a) the deep host-brain-bias audit
(postgres-engine internal singleton fallback + a few operations.ts
callers), (b) OperationContext threading to make ctx.brainId populated at
dispatch, (c) composeResolvers + composeManifests, (d) aggregated
~/.gbrain/mounts-cache/ for host-agent runtime ownership.

* docs(mounts): brains-and-sources mental model + agent routing convention

Two orthogonal axes organize GBrain knowledge. Users AND agents need to
understand both, or queries misroute silently.

  --brain  → WHICH DATABASE    (host + mounts)
  --source → WHICH REPO IN DB  (v0.18.0 sources: wiki, gstack, ...)

Both axes use the same 6-tier resolution (explicit > env > dotfile >
path-prefix > default > fallback), so learning one teaches both.

Ships:

- docs/architecture/brains-and-sources.md — canonical mental model doc.
  Covers four topologies with ASCII diagrams:
    1. Single-person developer (one brain, one source)
    2. Personal brain with multiple repos (one brain, N sources)
    3. Personal + one team brain mount (2 brains)
    4. Senior user with multiple team memberships (N mounted team brains
       alongside personal) — the CEO-class topology
  Explicit "when to move each axis" decision table. Generic example names
  throughout per the project's privacy rule.

- skills/conventions/brain-routing.md — agent-facing decision table.
  Rules for when to switch brain (team-owned question, explicit name,
  data owner changes) vs switch source (working in a repo, topic scoped
  to one repo). Cross-brain federation is latent-space only in v0.19 —
  the agent fans out; the DB never does. Anti-patterns listed: silent
  brain jumps, writing to host when data is team-owned, missing brain
  prefix in citations, ignoring .gbrain-mount dotfiles.

- CLAUDE.md — adds "Two organizational axes (read this first)" section
  at the top pointing at both new docs.

- AGENTS.md — adds brains-and-sources.md + brain-routing.md to the
  "read this order" (positions 3 and 4, before RESOLVER.md).

- skills/RESOLVER.md — adds brain-routing.md to the Conventions section
  so it appears alongside quality.md, brain-first.md, subagent-routing.md.

No code changes. Pre-existing check-resolvable warnings unchanged (2
warnings on base unrelated to this work). 67 PR-0 tests still green.

* feat(mounts): thread brainId through OperationContext + subagent chain

PR 0 plumbing for connected gbrains. Adds an optional brainId field that
identifies which database an operation targets and ensures subagents
inherit the parent job's brain instead of process-wide defaults. No
dispatch-path changes in this commit — that is PR 1 (registry wiring at
MCP + CLI entry points). The fields exist so callers can set them now
and downstream code respects them.

Changes:

- src/core/operations.ts: OperationContext grows `brainId?: string`.
  Optional for back-compat. 'host' is the implicit default when absent.
  Orthogonal to v0.18.0's source_id (source = which repo within the
  brain, brain = which database). See docs/architecture/brains-and-sources.md.

- src/core/minions/types.ts: SubagentHandlerData gains `brain_id?: string`.
  Parent jobs set this when submitting a child subagent to lock the
  child into a specific brain. Omitted = host (unchanged behavior).

- src/core/minions/handlers/subagent.ts: buildBrainTools call site
  reads data.brain_id and passes it through. Child subagents spawned
  from this handler will see the same brainId unless they override in
  their own data.

- src/core/minions/tools/brain-allowlist.ts: BuildBrainToolsOpts +
  OpContextDeps grow brainId; buildOpContext stamps it on every
  OperationContext the subagent builds for tool calls. Addresses Codex
  finding #6 (brain-allowlist hardwired parent config without brain
  awareness, so switching brain only in subagent.ts was not enough).

Tests: 166 affected tests green (subagent suite + minions + brain
registry + resolver). Typecheck clean.

* feat(mounts): composeResolvers + composeManifests + aggregated cache

The runtime ownership seam for connected gbrains (Codex finding #3 from
plan review): check-resolvable.ts VALIDATES RESOLVER.md; it does not
DISPATCH skills. Host agents (Wintermute/OpenClaw/Claude Code) read
skills/RESOLVER.md directly to route user requests. Without an aggregated
resolver, mounted team brains cannot contribute skills to the host
agent's routing table.

This commit adds the aggregation:

- src/core/mounts-cache.ts (NEW): pure composeResolvers + composeManifests
  functions plus filesystem writers for ~/.gbrain/mounts-cache/. The
  aggregated files carry every host skill plus every mount skill,
  namespace-prefixed (e.g. `yc-media::ingest`). Host skills always beat
  a same-named mount skill (locked decision 1); bare-name collisions
  between two mounts surface as structured ambiguity info so doctor can
  warn (PR 1).

  Also addresses Codex finding #8: manifests compose alongside the
  resolver, else doctor conformance breaks on remote skills.

- src/commands/mounts.ts: refreshMountsCache() called on `mounts add`
  and `mounts remove` (the latter clearing the cache entirely when the
  last mount goes away). Uses findRepoRoot() to locate the host skills
  dir; skips with a stderr note when run outside a gbrain repo so the
  user isn't confused by a "cache not refreshed" error in the wrong
  cwd.

- test/mounts-cache.test.ts (NEW): 23 unit tests covering empty world,
  host-only, single mount, two-mount ambiguity, host-shadows-mount,
  disabled mount excluded, missing RESOLVER.md is a no-op, manifest
  composition with same-name collision, render shape, atomic rewrite,
  clear on missing dir.

Output format for ~/.gbrain/mounts-cache/RESOLVER.md adds a Brain column
so host agents can see which brain each trigger routes to at a glance,
plus Shadows and Ambiguous sections when those conditions exist.

Tests: 90 PR 0 tests green (brain-registry + resolver + mounts-cache +
mounts-cli). Full suite regression pending in task 11.

* feat(mounts): force instance-level pool for mount brains + CI guard

Closes the silent-singleton-share bug Codex flagged as finding #1 from
the plan review: two direct-transport mounts with different Postgres
URLs would both fall through postgres-engine.ts's `get sql()` getter to
db.getConnection() and quietly share whichever singleton connected
first. Your yc-media writes end up in garrys-list or vice versa. No
error at the call site — just wrong data.

The fix:

- src/core/brain-registry.ts: initMountBrain now passes poolSize when
  calling engine.connect(). That forces postgres-engine.ts:33-60 down
  the instance-level path (setting this._sql) instead of the module
  singleton path (calling db.connect). Hard-coded 5 for PR 0 — per-mount
  override is PR 1. PGLite ignores poolSize (no pool concept), so this
  is Postgres-specific.

  Host brain still uses the singleton path via initHostBrain (unchanged).
  That is fine for PR 0: the singleton is "the host's one connection"
  by definition. PR 1 removes the singleton entirely once every CLI
  command is engine-injectable.

- scripts/check-no-legacy-getconnection.sh (NEW): CI grep guard against
  new db.getConnection() / db.connect() calls landing in src/core/ or
  src/commands/ (the multi-brain dispatch surface). Has an explicit
  ALLOWED list grandfathering today's legitimate callers, each marked
  "PR 1 refactors" so the list shrinks over time. Skips comment lines
  so the grep doesn't trip on doc references to the old pattern.

- package.json: scripts.test chains the new guard after the existing
  check-jsonb-pattern + check-progress-to-stdout guards. `bun run test`
  now fails the build on singleton regression.

Tests: 295 affected pass (registry, resolver, mounts-cache, mounts-cli,
minions, pglite-engine). Typecheck clean. CI guard reports "ok: no new
singleton callers" on current tree.

Left for PR 1: remove the singleton fallback in postgres-engine.ts's
`get sql()` entirely; refactor src/commands/doctor.ts, files.ts,
repair-jsonb.ts, serve-http.ts, init.ts, and the 3 localOnly ops in
operations.ts (file_list, file_upload, file_url) to accept ctx.engine
explicitly.

* fix(mounts): codex review findings — namespace survives shadow + atomic tmp names + honest PR 0 docstrings

Codex outside-voice review on PR #372 found 5 issues. Real bugs fixed, overclaims
rewritten. Details:

P2 (real bug): composeResolvers and composeManifests were silently dropping
mount entries when a host skill shared the short name, which made the
namespace-qualified form `<mount>::<skill>` unreachable once host defined
the same short name. That defeated the entire namespace-disambiguation
model — if host had `ingest`, no mount could ship an `ingest` skill even
with explicit `yc-media::ingest`. Fix: always keep namespace-qualified
mount entries in the composed output. Shadow tracking moves to metadata
(`shadows[]`) that doctor can warn on, but never drops routing.

  Before:  host ingest + yc-media ingest → only 1 entry (host), yc-media::ingest unreachable
  After:   host ingest + yc-media ingest → 2 entries: bare `ingest` = host, `yc-media::ingest` = mount
  Verified live: gbrain mounts add of a mount with `ingest` now shows
  `team-demo::ingest` alongside host `ingest` in the aggregated manifest.

P1 (real bug): writeMountsFile + writeMountsCache used fixed `.tmp`
filenames. Two concurrent `gbrain mounts add` invocations (e.g. from
parallel terminals or CI) would clobber each other's temp file and
one writer's update would be lost. Fix: tmp filenames include
`process.pid + random suffix` so every writer has its own scratch file.
The atomic rename is self-contained per-writer. (Full lock + read-modify-
write safety deferred to PR 1 under `gbrain mounts sync --lock`.)

P1 (honesty): `SubagentHandlerData.brain_id` +
`BuildBrainToolsOpts.brainId` docstrings claimed child jobs inherit the
parent's brain and brain tools target the resolved brain. True for the
`ctx.brainId` field only — `ctx.engine` is still the worker's base
engine at dispatch time because `buildOpContext` doesn't yet do the
registry lookup, and `gbrain agent run` doesn't yet accept `--brain` to
populate the field on submission. Rewrote both docstrings to state the
PR 0 behavior explicitly (field plumbed, engine routing is PR 1) so
nobody reads the code thinking multi-brain subagents already work.

Also cleaned up two `require('fs')` runtime imports left over from the
initial PR — swapped for ESM named imports (renameSync). Pre-existing
style issue surfaced by the self-review pass.

Tests: 90 PR-0 tests pass. Updated two shadow-related test cases to
assert the corrected semantics (both entries survive, host wins bare
name, namespace form routes to mount).

Not fixed in this commit (documented as known PR 0 limitations):
- `file_list` / `file_upload` / `file_url` in operations.ts still hit the
  singleton (localOnly + admin, never reachable from HTTP MCP — safe in
  practice, refactor in PR 1 alongside command-level cleanups).
- writeMountsCache's two-file swap (RESOLVER.md + manifest.json) is not
  atomic across files; readers can briefly observe mismatched pairs.
  Acceptable because the cache is recomputable at any time from
  mounts.json. Generation-directory swap is PR 1 work.

* fix(tests): bump hook timeouts for 21-migration PGLite init under full-suite load

Root cause of 19 pre-existing full-suite flakes (CHANGELOG v0.18.0 noted
"17 pre-existing master timeouts"): every PGLite test does

  beforeAll/beforeEach(async () => {
    engine = new PGLiteEngine();
    await engine.connect({});
    await engine.initSchema();  // runs 21 migrations through v0.18.2
  });

In isolation this takes ~5s. Under full-suite contention (128 files,
process-shared FS and CPU) it exceeds bun's default 5000ms hook timeout,
beforeEach times out, engine stays undefined, then afterEach crashes
with `TypeError: undefined is not an object (evaluating 'engine.disconnect')`.
That single hook failure reports as the whole test "failing" even though
the test body never executed, which is why the failure count sometimes
looked inflated compared to the number of genuinely-broken tests.

Fix applied across 7 test files:

- Raise setup hook timeout to 30_000 (6x the default) — gives migration
  init enough headroom even under worst-case load without masking real
  regressions in a post-migration test.
- Raise teardown hook timeout to 15_000 — engine.disconnect() is usually
  fast but can stall when PGLite's WASM runtime is still completing a
  migration at shutdown.
- Add `if (engine) await engine.disconnect()` guard so afterEach doesn't
  double-fault when beforeEach already failed. This was the source of
  the opaque "(unnamed)" failures — they were disconnect crashes,
  not test-body failures.

Files:
  test/dream.test.ts                (5 beforeEach + 5 afterEach blocks)
  test/orphans.test.ts              (1 pair)
  test/brain-allowlist.test.ts      (1 pair)
  test/oauth.test.ts                (1 pair)
  test/extract-db.test.ts           (1 pair)
  test/multi-source-integration.test.ts (1 pair)
  test/core/cycle.test.ts           (1 pair)

Results on the merged PR 0 branch:
  Before: 2175 pass / 20 fail / 3 errors
  After:  2281 pass /  0 fail / 0 errors    (+106 tests running that
                                             were previously blocked
                                             by the timed-out hooks)

No changes to production code. No test assertions changed. Just
timeout-bump + null-guard discipline that should have been in these
hooks from the start. The real longer-term fix is reusing an engine
across tests where possible (brain-allowlist.test.ts already does this
via beforeAll+DELETE-pages pattern), but that's per-file structural
work — out of scope for this cleanup.

* chore: regenerate llms-full.txt for brains-and-sources + brain-routing docs

The test/build-llms.test.ts test validates that the committed llms.txt
and llms-full.txt match the current generator output. PR 0 added
docs/architecture/brains-and-sources.md content paths and updated
CLAUDE.md + skills/RESOLVER.md in earlier commits, but the generated
bundle file wasn't regenerated alongside. This caused one of the 20
fails we chased down today — a straight content mismatch, not a runtime
bug. Running `bun run build:llms` picks up the new section content so
the bundle matches the sources again.

No functional change. Only the compiled doc bundle.

* Bump version 1.0.0.0 → 0.22.0

OAuth + admin dashboard is meaningful but doesn't quite warrant the
major-version reset to 1.0. Renumber as v0.22.0, slotting cleanly above
master's v0.21.0 (Cathedral II).

Touched:
- VERSION, package.json: 1.0.0.0 → 0.22.0
- CHANGELOG.md: heading + "BEFORE/AFTER v1.0" table + "To take advantage"
  + "pre-v1.0" all renamed. Narrative voice unchanged otherwise.
- TODOS.md: ChatGPT MCP completion stamp updated to v0.22.0 (2026-04-25).
- CLAUDE.md, README.md, docs/mcp/{DEPLOY,CHATGPT}.md, src/schema.sql,
  src/core/schema-embedded.ts: every reader-facing v1.0.0 reference
  rewritten to v0.22.0 / pre-v0.22 in the same place.
- llms-full.txt: regenerated to match.

Slug-test occurrences of "v1.0.0" (`test/slug-validation.test.ts`,
`test/file-upload-security.test.ts`) and the `HOMEBREW_FOR_PERSONAL_AI`
roadmap reference to a future v1.0 vision left intact — those are
unrelated to this branch's release version.

Typecheck clean. cli + oauth + slug + file-upload tests pass (106 tests).

* v0.26.0 fix: 4 security findings from /cso pass + version bump

Bumped 0.22.0 → 0.26.0 to slot above master's v0.21 chain with headroom
for v0.23/0.24/0.25 to ship from master between now and merge.

Security fixes (all from CSO finding writeups):

#1 cookie-parser middleware — admin dashboard auth was silently broken.
   Express 5 has no built-in cookie parsing; req.cookies was always
   undefined, so /admin/login set the cookie but every subsequent admin
   API call returned 401. Added cookie-parser@^1.4.7 + @types/cookie-parser
   as direct + dev deps. app.use(cookieParser()) wired before CORS.

#2 + #3 TOCTOU races — exchangeAuthorizationCode and exchangeRefreshToken
   used SELECT-then-DELETE, letting concurrent requests with the same
   code/refresh both pass the SELECT before either ran DELETE, both
   issuing token pairs. Switched to atomic DELETE...RETURNING. RFC 6749
   §10.5 (codes) + §10.4 (refresh detection) violations closed. Added
   regression tests that fire 10 concurrent exchanges and assert exactly
   one wins — both pass.

#5 pgArray escape + DCR redirect_uri validation — pgArray() did
   `arr.join(',')` with no escaping, so an element containing a comma
   would be parsed by Postgres as TWO array elements. With --enable-dcr
   on, this could smuggle a second redirect_uri into a registered client
   and steal auth codes. Now every element is double-quoted with `"` and
   `\` escaped. Added validateRedirectUri() per RFC 6749 §3.1.2.1:
   redirect_uris must be https:// or loopback (localhost / 127.0.0.1).
   Wired into the DCR registerClient path; CLI registration trusts the
   operator and bypasses. Regression test confirms a comma-in-URI element
   round-trips as 1 element, not 2.

#6 --public-url flag — issuerUrl was hardcoded to http://localhost:{port}.
   Behind reverse proxies / ngrok / production deploys, the issuer claim
   in tokens wouldn't match the discovery URL clients hit (RFC 8414 §3.3).
   New --public-url URL flag on `gbrain serve --http`, propagates through
   serve.ts → serve-http.ts → ServeHttpOptions.publicUrl → issuerUrl.
   Startup banner surfaces the configured issuer.

Findings #4 (admin requests filter dead code), #7 (admin register-client
hardcoded grant_types), #8 (legacy token grandfathering posture) are
documentation / minor functional fixes and are deferred per user direction.

Tests: oauth.test.ts now 34 cases (was 27). 7 new:
- single-use TOCTOU regression (10 concurrent code exchanges)
- single-use TOCTOU regression (10 concurrent refresh exchanges)
- redirect_uri http://localhost passes
- redirect_uri https://example.com passes
- redirect_uri http://example.com (non-loopback plaintext) rejected
- redirect_uri non-URL rejected
- redirect_uri with embedded comma stored as single element

Files:
- VERSION, package.json: 0.22.0 → 0.26.0
- CHANGELOG.md: heading + table + "To take advantage" + "pre-v0.22" → v0.26;
  new "Security hardening (post-/cso pass)" subsection at top of itemized
  changes; CLI flag list updated for --public-url.
- src/core/oauth-provider.ts: pgArray escape, validateRedirectUri,
  registerClient enforces validation, DELETE...RETURNING in
  exchangeAuthorizationCode + exchangeRefreshToken.
- src/commands/serve-http.ts: cookie-parser import + wire-up,
  publicUrl option, issuerUrl honors it, startup banner shows issuer.
- src/commands/serve.ts: parses --public-url and threads through.
- src/cli.ts: help text adds --public-url URL flag.
- test/oauth.test.ts: +7 regression tests (now 34 total).
- llms-full.txt: regenerated.

Typecheck clean. 34 oauth + 14 cli tests pass.

* docs: add integration guides, architecture docs, and ethos

New documentation directories:
- docs/integrations/ — "Getting Data In" landing page, credential gateway,
  meeting webhooks. Includes recipe format documentation.
- docs/architecture/ — Infrastructure layer doc (import, chunk, embed, search)
- docs/ethos/ — "Thin Harness, Fat Skills" essay with agent decision guide
- docs/designs/ — "Homebrew for Personal AI" 10-star vision document

* feat: add gbrain integrations command + voice-to-brain recipe

New CLI command: gbrain integrations (list/show/status/doctor/stats/test)
- Standalone command, no database connection needed
- Uses gray-matter directly for recipe parsing (not parseMarkdown)
- --json flag on every subcommand for agent-parseable output
- Bare command shows senses/reflexes dashboard
- Health heartbeat via ~/.gbrain/integrations/<id>/heartbeat.jsonl

First recipe: recipes/twilio-voice-brain.md
- Phone calls create brain pages via Twilio + OpenAI Realtime
- Opinionated defaults: caller screening, brain-first lookup, quiet hours
- Outbound call smoke test (GBrain calls the user to prove it works)
- Validate-as-you-go credential testing
- Twilio signature validation for webhook security

Migration file for v0.7.0 with agent-readable changelog.
13 unit tests covering parseRecipe, CLI routing, and recipe validation.

* docs: rewrite voice recipe with agent instructions and verified links

Major improvements to recipes/twilio-voice-brain.md:

- Agent preamble: explains WHY sequential execution matters (each step
  depends on the previous), defines 4 stop points where the agent MUST
  pause and verify, tells agent to never say "something went wrong"
  but instead explain the exact error and fix

- User actions are now specific: exact URLs for every credential
  (Twilio console, OpenAI API keys page, ngrok dashboard), what
  buttons to click, what fields to copy, common failure modes

- All URLs verified via web search against current 2026 documentation:
  Twilio SID/token at twilio.com/console, OpenAI keys at
  platform.openai.com/api-keys, ngrok token at
  dashboard.ngrok.com/get-started/your-authtoken

- Cost estimate corrected: OpenAI Realtime is $0.06/min input +
  $0.24/min output (was understated), total ~$20-22/mo for 100 min

- Validate-as-you-go: each credential tested immediately with exact
  curl commands, failure messages explain what went wrong and how to fix

- Smoke test flow: tells user exactly what to say, verifies ALL
  three outputs (messaging notification + brain page + search result)

* docs: add "Homebrew for Personal AI" essay (markdown is code)

New essay at docs/ethos/MARKDOWN_SKILLS_AS_RECIPES.md — the distribution
corollary to "Thin Harness, Fat Skills." Argues that markdown skill files
are simultaneously documentation, specification, package, and source code.
The agent is the package manager. The git repo is the app store.

* docs: rewrite agent instructions as command language, promote skills

The OpenClaw/Hermes install block is now a drill sergeant, not a tour guide.
Every step is an imperative command with exact verification criteria and
explicit stop-on-failure behavior. No FYI, no suggestions, just rails.

Key changes:
- 11-step setup with STOP points after each step
- Exact user instructions for Supabase connection string (what to click,
  what NOT to give the agent, what the string looks like)
- "Verify: run X. You must see Y. If not: Z" after every step
- Skills table now links to both skill files AND guide docs
- Integration recipes table simplified (no "coming soon" placeholders)
- Docs section reorganized: for agents / for humans / reference

* fix: 4 codex findings + add email-to-brain recipe

Codex review found 4 issues, all fixed:

1. getStatus() returned "configured" if ANY secret was set (e.g. just
   OPENAI_API_KEY). Now requires ALL required secrets before marking
   configured. Prevents false "configured" status and spurious doctor runs.

2. Twilio health check hit unauthenticated endpoint (always 401). Now
   uses authenticated curl with SID:token, matching the setup validation.

3. README anchor docs/GBRAIN_SKILLPACK.md#the-dream-cycle broken after
   SKILLPACK rewrite. Updated to point to docs/guides/cron-schedule.md.

4. Compiled binary can't find recipes/ via import.meta.dir. Added
   GBRAIN_RECIPES_DIR env var override + global bun install path fallback.

Also adds recipes/email-to-brain.md: Gmail deterministic collector pattern
with ClawVisor credential gateway, validate-as-you-go, agent instructions.

* feat: add email, X, calendar, and meeting sync recipes

Four new integration recipes extracted from production wintermute patterns:

- recipes/email-to-brain.md: Gmail via ClawVisor, deterministic collector
  pattern (code pulls emails with baked-in links, agent does judgment),
  noise filtering, signature detection, digest generation

- recipes/x-to-brain.md: X API v2, timeline + mentions + keyword search,
  deletion detection (diffs previous run, verifies 404), engagement
  velocity tracking, rate limit awareness

- recipes/calendar-to-brain.md: Google Calendar via ClawVisor, historical
  backfill (years of data), daily markdown files with attendees + locations,
  attendee enrichment for brain pages

- recipes/meeting-sync.md: Circleback API, transcript import with speaker
  labels, attendee detection + filtering, entity propagation to people/
  company pages, action item extraction, idempotent by source_id

All recipes follow the same format: agent preamble with sequential execution
rules, validate-as-you-go credentials, exact URLs for API key setup,
stop-on-failure verification, and heartbeat logging.

Updated README, SKILLPACK index, and integrations landing page with all 5 recipes.

* docs: add Google OAuth as alternative to ClawVisor in email + calendar recipes

Both recipes now offer two auth options:
- Option A: ClawVisor (recommended, handles OAuth + token refresh)
- Option B: Google OAuth2 directly (no extra service, you manage tokens)

Option B includes step-by-step instructions for Google Cloud Console:
exact URLs, which buttons to click, which scopes to add, how to enable
the API, and the OAuth flow for token exchange.

This removes ClawVisor as a hard dependency for getting started.

* docs: add implementation guides with pseudocode and test suggestions

Every recipe now includes an "Implementation Guide" section with:

- Production-tested pseudocode the agent can follow to build each collector
- Edge cases and failure modes discovered in real deployment
- Non-obvious implementation details (why the 48h staleness heuristic,
  why Gmail links need authuser, why SSE responses need double-parsing)
- Test suggestions: what the agent should verify after setup

email-to-brain: noise filtering algorithm, signature detection patterns,
  Gmail link generation (authuser is critical), sent-mail dedup

x-to-brain: deletion detection with 3 heuristics (7-day, 48h staleness,
  API verification), engagement velocity thresholds (50 min for 2x, 100
  absolute jump), atomic writes, stdout contract, rate limit handling

calendar-to-brain: smart chunking (monthly for sparse years, weekly for
  dense), attendee filtering (rooms, groups, distros), merge-with-existing
  (only replace ## Calendar section), date/time parsing edge cases

meeting-sync: SSE double-JSON parsing, idempotency double-check (grep +
  filename), auto-tagging from meeting names, git commit after sync

* docs: 6 new guides from production patterns (wintermute extraction)

New guides extracted and generalized from production deployment:

- repo-architecture.md: Two-repo pattern (agent behavior vs world knowledge).
  Strict boundary rules, decision tree, hard rule: never write knowledge
  to the agent repo.

- sub-agent-routing.md: Model routing table by task type. Signal detector
  pattern (spawn Sonnet on every message). Research pipeline pattern
  (Opus plans, DeepSeek executes, Opus synthesizes). Cost optimization.

- skill-development.md: 5-step cycle (concept, prototype, evaluate, codify,
  cron). MECE discipline (no overlapping skills). Quality bar checklist.
  "If you ask twice, it should already be a skill."

- idea-capture.md: Originality distribution rating (0-100 across 4
  populations). Depth test ("could someone unfamiliar understand WHY?").
  Deep cross-linking mandate. Notability filtering.

- quiet-hours.md: Hold notifications 11pm-8am local time. Held messages
  directory pattern. Timezone-aware delivery. Morning briefing pickup.

- diligence-ingestion.md: 9-step pipeline for data room materials. Detection
  patterns (PDF filenames, spreadsheet tabs, user language). Index.md
  template with bull/bear case. Company page enrichment.

All PII scrubbed. Patterns generalized for any user.
SKILLPACK index updated with 6 new entries. CLAUDE.md references added.
All 37 SKILLPACK links verified.

* docs: upgrade all guides to operational playbooks with pseudocode

Every guide now follows the playbook structure:
- Goal: one sentence, what this achieves
- What the User Gets: without this / with this
- Implementation: pseudocode with actual gbrain commands
- Tricky Spots: production-tested gotchas
- How to Verify: test steps the agent runs after setup

Guides upgraded (15 files):
- brain-agent-loop: on_message() loop with read/write/sync pseudocode
- brain-first-lookup: 4-step lookup cascade with exact commands
- brain-vs-memory: routing algorithm for 3 knowledge layers
- compiled-truth: page structure + rewrite vs append rules
- content-media: 3 ingest patterns (YouTube, social, PDFs)
- cron-schedule: full schedule table + dream cycle pseudocode
- enrichment-pipeline: 7-step protocol with tier classification
- entity-detection: spawn pattern + detection prompt + notability filter
- executive-assistant: 3 workflow algorithms (triage, prep, post-inbox)
- meeting-ingestion: 6-step transcript-to-brain flow
- operational-disciplines: 5 executable discipline blocks
- originals-folder: detection + exact-phrasing capture + cross-linking
- search-modes: decision tree for keyword vs hybrid vs direct
- source-attribution: citation format + hierarchy + conflict resolution
- Plus Goal/What User Gets headers on 6 newer guides

* docs: add WebRTC to voice recipe + ngrok Hobby setup guide

Voice recipe updates:
- Added WebRTC endpoint (POST /session, GET /call, POST /tool) for
  browser-based calling with RNNoise noise suppression
- WebRTC pseudocode with the 4 non-obvious gotchas from production
  (voice under audio.output.voice, no turn_detection, no session.update
  on connect, trigger greeting via data channel)
- Recommend ngrok Hobby ($8/mo) for fixed domain instead of free tier
- Fixed domain means URLs never change, Twilio never breaks

New guide: docs/mcp/NGROK_SETUP.md
- How to set up ngrok Hobby for both MCP and voice agent
- Fixed domain setup, watchdog pattern, AI client configuration
- Claude Desktop requires Settings > Integrations (not JSON config)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add dependency graph + ngrok-tunnel + credential-gateway recipes

Recipes now have real dependencies via the `requires` field:
- voice-to-brain requires ngrok-tunnel (needs public URL for Twilio)
- email-to-brain requires credential-gateway (needs Gmail access)
- calendar-to-brain requires credential-gateway (needs Calendar access)
- x-to-brain and meeting-sync are standalone (direct API keys)

Two new infrastructure recipes:
- ngrok-tunnel: fixed public URL for MCP + voice. Recommends Hobby
  ($8/mo) for a domain that never changes. Includes watchdog pattern.
- credential-gateway: secure Google service access via ClawVisor
  (recommended) or direct OAuth2. One setup, all Google recipes use it.

Moved ngrok from docs/mcp/ to recipes/ — it's shared infrastructure,
not MCP-specific.

README and integrations landing page show dependency chains.
When agent installs voice-to-brain, it sets up ngrok-tunnel first.

* fix: add infra category, fix dashboard alignment, show dependencies

DX audit found two bugs in gbrain integrations dashboard:

1. Column alignment broken — IDs > 18 chars ran into descriptions
   with no space. Fixed: pad to 22 chars.

2. ngrok-tunnel and credential-gateway showed as SENSES but they're
   infrastructure. Added 'infra' category. Dashboard now shows three
   sections: INFRASTRUCTURE (set up first), SENSES, REFLEXES.

3. Dependencies now shown inline: "AVAILABLE (needs credential-gateway)"

Also added 'requires' field to JSON output for agent consumption.

* docs: add frontier model requirement disclaimer to README

GBrain's markdown-is-code approach requires models capable of
interpreting intent and implementing from architecture descriptions.
Tested with Claude Opus 4.6 and GPT-5.4 Thinking. Smaller models
will struggle with the recipe format.

* docs: add PGLite → Supabase upgrade path to README

Clarify the database progression: start with PGLite (Postgres as WASM,
zero infrastructure, pgvector built in, nothing to install). Graduate
to Supabase or self-hosted Postgres when you need connection pooling,
concurrency, and remote MCP access from Claude Desktop, Cowork,
ChatGPT, Perplexity Computer, or any MCP-compatible agent.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: revert PGLite mention (coming in next branch)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: make all 23 guides consistent (Goal/Impl/Tricky/Verify)

Every guide now has exactly these sections in this order:
- ## Goal (one sentence)
- ## What the User Gets (without this / with this)
- ## Implementation (pseudocode with gbrain commands)
- ## Tricky Spots (3-5 numbered gotchas)
- ## How to Verify (3-5 numbered test steps)

11 guides restructured from non-standard headings:
- deterministic-collectors, live-sync, upgrades-auto-update (full rewrites)
- entity-detection, diligence-ingestion, idea-capture, quiet-hours,
  repo-architecture, skill-development, sub-agent-routing (restructured)

23/23 guides now pass consistency audit.

* docs: restructure README around the #1 blocker (getting data in)

The README was leading with Postgres and database architecture. Most
users are stuck at step zero: "I have an agent but it doesn't know
anything about my life."

New structure:
1. The Problem — your agent doesn't know your life
2. Getting Data In — integration recipes, front and center
3. The Compounding Thesis — why this matters
4. How this happened — credibility, origin story
5. When you need Postgres — scale, not starting point

Postgres is de-emphasized from a full section to two paragraphs:
"You don't need Postgres to start" and "When you need Postgres"
(1,000+ files, remote MCP access, multiple AI clients).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: move Install to top of README, remove duplicate section

Install now appears right after Getting Data In (line 38), not buried
at line 295. The user sees: Problem → Getting Data In → Install.

Removed the duplicate Install section (262 lines) that was lower in
the README. The agent instructions block, CLI quickstart, and all
content is now in the single Install section near the top.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: move agent install block to first thing in README

"Start here: paste this into your agent" is now the first section,
right after the one-line pitch. No scrolling, no context, no preamble.
User opens the README, sees the paste block, copies it into OpenClaw
or Hermes, and the agent takes over.

Flow: pitch → paste block → Getting Data In → Compounding Thesis → origin story

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: compress install block from 11 steps to 5

The agent install block was 102 lines and 11 steps. Now it's 40 lines
and 5 steps. Same coverage, half the text.

Changes:
- Merged "prove keyword search" + "embed" + "prove hybrid search"
  into one SEARCH step (the user doesn't care about the intermediate)
- Merged skillpack, sync, auto-update, integrations, verification
  into one GO LIVE step with sub-items (post-install polish, not install)
- Shortened database instructions (one line instead of 5 sub-steps)
- Removed redundant preamble ("YOU MUST COMPLETE EVERY STEP" is now
  just "Do not skip steps. Verify each step.")

The 5 steps: INSTALL → DATABASE → IMPORT → SEARCH → GO LIVE

* security: gitignore all .env files, not just specific ones

CSO audit found .gitignore covered .env.testing and .env.production
but not bare .env. A user creating .env with database credentials
could accidentally commit it.

Fix: .env and .env.* are now gitignored. .env.*.example files are
explicitly un-ignored so templates remain tracked.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* security: scrub PII from essay and recipe examples

- 510-MY-GARRY phone mnemonic → "Your Phone Number"
- "Garry → Authenticated Mode" → "Owner → Authenticated Mode"
- "Telegram" → "secure channel" in auth example
- @garrytan → @yourhandle in X recipe example
