a46f28a63e fix(cli): keep doctor --json stdout clean — v123 migration handler printed to stdout (#3019)
The v123 configurable-FTS migration (#2941) logged its completion notice
via console.log. Migrations run lazily inside any command's first DB
connect, so on the nightly heavy run (fresh Postgres service DB) the
line landed as the first line of `gbrain doctor --json` stdout and broke
the fm_wallclock jq parse ("Invalid numeric literal at line 1, column 7",
run 29731426470). runMigrations' contract routes all migration noise to
stderr; move the v123 prints (and the pre-existing v2 slug-rename print)
there.

Also un-vacuous the fm_wallclock harness: its register-source step used
`bun run -e` (bun dumps usage with exit 0 instead of running the code)
and `connect({})` (in-memory), so the source was never registered and
doctor scanned nothing. It now resolves the engine the way the CLI does
and registers the source in the DB doctor actually reads.

Regression test: test/migrate-stdout-clean.test.ts re-runs migrations
from v122 asserting zero stdout writes, plus a source-level guard that
migrate.ts contains no console.log.

eefe8b5741 v0.42.1.0 feat: gbrain skillopt — self-evolving skills (closes #1481) (#1563)
* feat(skillopt): foundation modules — types, lr-schedule, benchmark, score, audit, lock

* feat(skillopt): edit primitives — apply-edits (D5+D9), rejected-buffer LRU, version-store (D8 history-intent-first)

* feat(skillopt): rollout (D2 gateway.toolLoop + D13 read-only allowlist), reflect (D7 two calls), validate-gate (D12 median+epsilon, D4 parallel), preflight (D3), bundled-skill-gate (D16)

* feat(skillopt): orchestrator (D6 slow-update, D10 ASCII diagrams, D11 caching), checkpoint, bootstrap (D15 sentinel), CLI dispatch + help

* feat(skillopt): cycle phase (F1 dream-loop wiring), PROTECTED_JOB_NAMES + MCP op (F6 admin scope + allowlist) + Minion handler (F7 --background)

* feat(skillopt): full cathedral — --all batch (F4), --target-models fleet (F5), write-capture (F10), held-out scaffold (F11), adversarial suite 41 cases (F2), E2E PGLite (F3), meta-skill bundle (T7), reflect+judge evals (F8+F9), docs (T10)

* chore: bump version to v0.42.0.0 (MINOR — significant new feature)

* fix(skillopt): wire trajectories from forward gate to reflect + fix parseEditsResponse parser misuse

Two related v0.42.0.0 bugs that conspired to make `runSkillOpt` structurally
unable to accept any candidate edit. Either alone would have killed self-evolution;
together they made the loop a no-op for every input.

**Bug 1 (orchestrator gap):** `runOptimizationLoop` in orchestrator.ts called
`runReflect({successes: [], failures: []})` with hardcoded empty arrays. The
forward gate's `scoredRollouts` were computed then voided. `runReflect`
short-circuits both modes when their batches are empty, so the optimizer was
never asked to propose an edit. Every step hit the no_edits_applied branch.

Fix: add `scoredRollouts: ScoredRollout[]` to `GateResult` and
`runsPerTask?: number` to `ValidateGateOpts`. Forward pass uses
`runsPerTask: 1`; orchestrator partitions returned rollouts by `score >= 0.5`
and threads real successes + failures into `runReflect`.

**Bug 2 (parser misuse):** `parseEditsResponse` in reflect.ts routed every
optimizer response through `parseJudgeJson` first. `parseJudgeJson` looks for
a `score` key (it's a judge-output parser, not an edits parser) and returns
null for any JSON without one — including the well-formed `{"edits": [...]}`
the optimizer is contractually required to emit. The function then early-
returned `[]` and the actual `tryExtractEdits` path on the next line was
unreachable dead code.

Fix: drop the wrong-typed guard. `parseEditsResponse` now calls
`tryExtractEdits` directly. Export it so `reflect.test.ts` can pin the
contract independently of the chat transport.

**Why this slipped through 152 prior skillopt tests:** zero unit coverage
of `parseEditsResponse` or `runReflect`. The existing E2E `all-reject` case
asserted no_improvement (which was true for the wrong reason — empty edits,
not gate rejection). Both bugs were structurally invisible to the existing
test surface.

**New coverage:**

- `test/skillopt/reflect.test.ts` (15 cases):
  - 8 `parseEditsResponse` cases including the IRON-RULE regression pin
    for the v0.42.0.1 fix (`{"edits": [...]}` JSON must survive the parser).
  - 7 `runReflect` D7 contract cases: both modes fire, empty-batch skips,
    additive token usage, one-mode-throws-other-still-works, rejected-buffer
    flows into anti-bias prompt.
  - Documents the trailing-comma limitation as an explicit out-of-scope pin
    (so a future tightening of `tryExtractEdits` lights this test up
    intentionally).

- `test/e2e/skillopt-loop.serial.test.ts` (7 cases):
  - HAPPY PATH: stubbed `gateway.chat` acts as both target agent (emits
    sections based on skill content) and optimizer (proposes a real
    add-Citations edit). Drives `runSkillOpt` end-to-end against PGLite.
    Asserts outcome=accepted, SKILL.md mutated with new section,
    frontmatter preserved (D5), history has one committed row,
    best.md mirrors disk, delta > epsilon, receipt fields populated.
  - 5 broken cases (each isolates a distinct orchestrator-visible failure):
    1. Below-baseline regression: optimizer proposes a destructive edit;
       gate rejects with reason=below_baseline; SKILL.md unchanged;
       rejected-buffer captures the bad edit for anti-bias context.
    2. Malformed reflect JSON: orchestrator degrades gracefully to
       no_improvement without crashing.
    3. Anchor-not-found: applyEditBatch rejects all; sel gate skipped;
       rejected-buffer captures with reason=apply_failed.
    4. Budget exhausted mid-step: outcome=aborted, no pending rows survive.
    5. Converged-skill re-run: starting from already-perfect skill →
       no_improvement (no thrash on a well-tuned starting point).
  - IDEMPOTENT RE-RUN: drive runSkillOpt twice in sequence. Run 1 accepts.
    Run 2 sees improved baseline, no failures, returns no_improvement.
    SKILL.md byte-identical to post-run-1; history still has exactly 1
    committed row. Proves stability at the fixed point.

All hermetic (no DATABASE_URL, no API keys). PGLite in-memory engine,
tempdir SKILL.md + benchmark, stubbed gateway.chat via
`__setChatTransportForTests`. `.serial.test.ts` because the stub installs
module state and the loop walks shared disk state across epochs.

Test counts after fix: 174 skillopt-surface tests pass (149 pre-existing
unit + 15 new reflect unit + 3 existing E2E + 7 new E2E). Typecheck clean.

* fix(cycle): align ALL_PHASES skillopt position with actual dispatch order

v0.42.0.0 added skillopt to ALL_PHASES right after `patterns` (line 127), but
the dispatch block in runCycle (line ~1912) actually runs skillopt between
`conversation_facts_backfill` and `embed`. The two were inconsistent, and the
serial test `report.phases.map(p => p.phase)).toEqual(ALL_PHASES)` was failing
on master because of it.

A second pre-existing failure: the two phase-count assertions in
`test/core/cycle.serial.test.ts` still said `toBe(20)` even though
ALL_PHASES grew to 21 when skillopt was added. The author bumped the array
but forgot the test.

Two fixes, one commit:

1. Move `'skillopt'` in ALL_PHASES from after `patterns` to between
   `conversation_facts_backfill` and `embed`, matching where runCycle
   actually dispatches it. Runtime behavior is unchanged — only the
   declaration order moves. Updated the surrounding comment to call out
   the position invariant and reference the test that pins it.

2. Update both `toBe(20)` assertions in cycle.serial.test.ts to `toBe(21)`
   with a v0.42.0.0 history line in the running comments.

Why declaration follows runtime (not the other way around): the comment
intent ("Runs AFTER patterns — graph-fresh") is still satisfied because
"after the entire main graph-mutating cluster" is strictly fresher than
"right after patterns". No design intent is lost.

Test result: cycle.serial.test.ts is now 28/28 (was 27/28 on master + my
prior commit). Skillopt suite still 174/174.

* fix(ci): bump PHASE_SCOPE assertion to 21 + fix skill-optimizer Anti-Patterns case

Two CI failures pre-existing on this branch since the v0.42.0.0 skillopt
cathedral landed; master is green because skillopt didn't exist there yet.

1. test/phase-scope-coverage.test.ts asserted ALL_PHASES.length === 20.
   skillopt is the 21st phase. Bumped to 21 with v0.42.0.0 history line
   in the comment chain. Sibling fix to the cycle.serial.test.ts bump
   in commit 08ad2468.

2. skills/skill-optimizer/SKILL.md had `## Anti-patterns` (lowercase p).
   skills-conformance.test.ts asserts `## Anti-Patterns` (capital P) as
   the required section header. Single-character rename.

Local: 174 skillopt-surface tests + 6 phase-scope tests + 249 skills-
conformance tests all green. Typecheck clean.

Remaining CI delta: 5 put_page facts backstop failures in shard 10 that
reproduce only on Linux CI, not locally even with empty env / cleared
HOME / max-concurrency=1. The error surface is `r.isError === true` with
no further detail captured in the bun:test output. Pushing these 2 fixes
first to narrow the CI signal; will instrument if the 5 persist.

* fix(e2e): align dream-cycle-phase-order + onboard-full-flow with v0.41/v0.42 reality

Two stale E2E assertion files surfaced by a full local E2E run against
real Postgres (the gbrain-test-pg container on port 5434). Neither file
is in the CI E2E job (CI only runs mechanical.test.ts + mcp.test.ts +
skills.test.ts + zeroentropy-live.test.ts), so the drift has been latent.

1. `test/e2e/dream-cycle-phase-order-pglite.test.ts`
   EXPECTED_PHASES was missing 4 phases that landed in master since the
   list was last revised:
     - extract_atoms (v0.41 T9 — atom extraction, after extract_facts)
     - synthesize_concepts (v0.41 T9 — concept synthesis, after patterns)
     - conversation_facts_backfill (v0.41.11.0, after calibration_profile)
     - skillopt (v0.42.0.0 — self-evolving skills, between
       conversation_facts_backfill and embed)
   Updated to 21 entries in the actual runtime dispatch order (matches
   ALL_PHASES exactly). 5/5 tests in the file pass after.

2. `test/e2e/onboard-full-flow.test.ts`
   `runAllOnboardChecks` shape test asserted exactly 4 checks; v0.42's
   type-unification cathedral (PR #1542, T13-T15) added 3 more
   (`pack_upgrade_available`, `type_proliferation`, `dangling_aliases`)
   for a total of 7. And `empty brain returns 0 remediations` regressed
   because `pack_upgrade_available` can emit a manual_only remediation
   on brains where gbrain-base@1.x is active and gbrain-base-v2 is
   registered as a successor. Tightened that assertion to `total <= 1`
   AND kept a per-check guard asserting takes_count remediations stay 0
   (the original test's load-bearing claim — A12 two-gate consent).
   13/13 tests in the file pass after.

Honest scope: 4 other E2E files still fail locally after this commit
(cycle.test.ts, dream.test.ts, phantom-redirect.test.ts,
sync-lock-recovery.test.ts), each for a distinct pre-existing master
bug unrelated to v0.42 skillopt work:
  - cycle.test.ts (5 fails): PostgresEngine.getConfig falls back to
    db.getConnection() singleton via the `get sql()` getter when no
    poolSize is set; the new conversation_facts_backfill phase chain
    hits this fallback even though the test's setupDB() connects both
    the singleton AND the engine. Race condition between the test's
    singleton lifecycle and the phase's getConfig call. Deeper fix
    needed in PostgresEngine.getConfig (use this._sql directly with
    explicit fallback only on user-driven CLI paths).
  - dream.test.ts (1 fail): expects "concepts/testing" slug to appear
    in dream cycle output, gets empty array. Related to v0.42 concept
    type-unification semantics.
  - phantom-redirect.test.ts (2 fails): concurrent-sync race +
    postgres-js text-string embedding survival. Master-level data-path
    bug; would need its own fix wave.
  - sync-lock-recovery.test.ts (1 fail): `gbrain sync --break-lock
    --all` exits 0 but test expects 1 with a shell-loop hint. CLI
    behavior changed in a master commit; need to either restore the
    refusal behavior or update the assertion.

None of these 4 block CI (E2E job doesn't run them). Filed as a
TODOS.md entry for a follow-up wave; the 2 in this commit are the
ones that mirror v0.42 work landing.

Local: 130/136 E2E files green, 927/940 tests pass (was 925/940
before these fixes; the 2 files this commit fixes added 7 newly-
passing tests).

* fix(ci): quarantine query-cache-knobs-hash.test.ts to serial runner

CI shard 10 (commit 4d721077) failed 5 tests in the
`SemanticQueryCache cross-mode isolation (CDX-4 hotfix)` describe block,
all ~7-34ms each, all expecting writes/reads to round-trip through one
shared PGLite engine + a `beforeEach DELETE FROM query_cache`. Passes
9/9 locally; fails 5/9 on Linux CI under bun's default in-file
max-concurrency=4.

Classic intra-file concurrency race shape: test A's `beforeEach`
clears the table → test A's `store` writes a row → test B's
`beforeEach` (concurrent with A's `store`) clears the table → test A's
follow-up COUNT query returns 0. Same root cause that quarantined
`embed-stale.test.ts`, `brain-allowlist.test.ts`, and
`schema-pack-find-pack-successors.test.ts` to the serial runner in
prior fix waves (documented in v0.41.22.0 CI fix wave).

Fix: rename to `query-cache-knobs-hash.serial.test.ts` so the v0.26.7
serial-tests runner picks it up at `max-concurrency=1`. Tests still
exercise the actual cache logic — no test deleted, no production code
changed. The describe block's `beforeAll` engine + `beforeEach`
TRUNCATE pattern works correctly at serial concurrency.

Local: 12/12 in this file + 52/52 in the serial runner. Production
SemanticQueryCache code is untouched.

* fix(heavy): frontmatter_scan_wallclock — opt into --no-embedding so CI runners work

Heavy tests workflow run 26542447602 (commit 483a5577) failed on the
first heavy script:

  [fm_wallclock] FAIL: gbrain init exited non-zero
  No embedding provider configured. Set one of:
    OPENAI_API_KEY / ZEROENTROPY_API_KEY / VOYAGE_API_KEY
  Or defer setup: gbrain init --pglite --no-embedding

The v0.37 D9 hard-require landed in init.ts: `gbrain init --pglite` now
refuses to proceed without an embedding provider configured. The
heavy-tests GitHub workflow doesn't pipe any embedding API keys
(deliberate — the heavy tests measure ops shape, not LLM behavior), so
every CI invocation now blocks at step 2 of this script.

The script's whole purpose is measuring `gbrain doctor`'s
frontmatter-scan wallclock — it never embeds, never calls
`gbrain embed`, never queries vectors. The right fix is to opt out of
the provider requirement via the same `--no-embedding` flag init.ts
already exposes for this exact "deferred setup" case.

Verified locally:
  TMP=$(mktemp -d); GBRAIN_HOME="$TMP" \
    bun run src/cli.ts init --pglite --yes --no-embedding
  # exit 0, brain initialized.

No production code change. One-line + comment in the script.

* fix(heavy): sync_lock_regression — pass --no-embed so CI runs measure lock contention, not key absence

Heavy tests workflow run 26542545802 (commit 7962d312, after the
previous fm_wallclock fix) failed at the next heavy script in the chain:

  [sync_lock_regression] outcomes: winners=0 losers=0 unknown=4
  [sync_lock_regression] FAIL: expected 1 winner, got 0
  [sync_lock_regression] FAIL: expected 3 lock-busy losers, got 0

Each of the 4 parallel `gbrain sync` invocations failed for the same
reason — none of them ever even got to the lock-acquire step:

    Embedding model "zeroentropyai:zembed-1" requires ZEROENTROPY_API_KEY.
    Re-run with --no-embed to import-only and embed later once the key is set.

The CI runner doesn't pipe any embedding-provider API keys (deliberate —
heavy tests measure ops shape, not LLM behavior), and sync now hard-fails
when its embed step can't reach a configured provider.

This script measures the writer-lock race shape — `gbrain-sync` row in
`gbrain_cycle_locks`, exactly-one-winner semantics, N-1 fail-fast losers
with "Another sync is in progress", zero leaked rows post-run. It never
needed embeddings; the original write predates the hard-require landing.

Fix: pass `--no-embed` to the sync invocation. Same kind of fix as
fm_wallclock (commit 7962d312) but on the sync side rather than init.

No production code touched. One-line change in the bash script.

* fix(heavy): sync_lock_regression — register source via psql + use --repo + tolerate doctor warns

Heavy tests run 26542638471 (commit 60145eee, after the --no-embed
fix) failed at the same script but at a downstream step:

  > Source "default" has no local_path. Run: gbrain sources add default --path <path>

Three independent bugs in the script that all surfaced at once after
v0.41's source-registry landed:

1. `gbrain config set sync.repo_path` is the legacy way; sync now
   reads `sources.local_path` first. Replaced with an upsert into the
   sources table via psql:
     INSERT INTO sources (id, name, local_path)
     VALUES ('default', 'default', $BRAIN_DIR)
     ON CONFLICT (id) DO UPDATE SET local_path = EXCLUDED.local_path
   Kept the legacy `config set sync.repo_path` line too as
   belt-and-suspenders for any downstream caller that still reads it.

2. `gbrain sync --dir <path>` is silently ignored; sync's CLI parser
   recognizes `--repo`, not `--dir`. Switched to `--repo`.

3. `bun run src/cli.ts doctor --json` at the top (used to apply
   migrations as a side effect) exits non-zero whenever ANY check
   warns — including the new "no embedding provider configured"
   warning on a fresh CI runner. The script's `set -e` aborted at
   line 53 before reaching any of the sync invocations. Added `|| true`
   since the migration runs regardless of doctor's exit verdict.

Verified locally — `DATABASE_URL=... bash tests/heavy/sync_lock_regression.sh`
output:
  [sync 1] rc= (lock-busy: 'Another sync is in progress')
  [sync 2] rc=0 (winner)
  [sync 3] rc= (lock-busy: 'Another sync is in progress')
  [sync 4] rc= (lock-busy: 'Another sync is in progress')
  outcomes: winners=1 losers=3 unknown=0
  post-run gbrain_cycle_locks(gbrain-sync) row count: 0
  OK — 1 winner, 3 lock-busy losers, no leaked lock rows.

Production code untouched. All three fixes are in the bash script.

* docs(skillopt): hands-on tutorial for auto-improving a skill + discoverability

There was no tutorial for skillopt — only a reference guide
(docs/guides/skillopt.md) that opens at --bootstrap-from-routing and
assumes you already understand benchmarks, and an agent-facing SKILL.md.
README had ZERO skillopt mention. The one thing a user must hand-author
(the benchmark JSONL) was taught nowhere with a worked example.

New: docs/tutorials/improving-skills-with-skillopt.md — Diataxis tutorial
(learning-oriented), copy-pasteable end to end:
  1. mental model in two sentences (SKILL.md is the trainable param, the
     agent is frozen)
  2. write your first benchmark from scratch — a complete 15-task rule-judge
     starter you paste and run, with the full check-op table
     (contains/regex/section_present/max_chars/min_citations/tool_called/
     tool_not_called)
  3. --dry-run cost preview (and that it exits 2 by convention, not failure)
  4. real run + reading accepted(0)/no_improvement(1)/aborted(2) with the
     actual stderr output shape
  5. where output lands (best.md, versions/, history.json, rejected.json,
     audit jsonl)
  6. accept/reject — bundled vs user skills, --no-mutate vs
     --allow-mutate-bundled
  7. iterate by sharpening the benchmark

The load-bearing fix the tutorial makes that the reference guide got wrong:
the DEFAULT --split 4:1:5 needs ~50 tasks before it runs (sel = N/10, floor
5). A first-time author writing 10-15 tasks hits `D_sel has N task(s)
(need >=5)` and bounces. The tutorial ships 15 tasks + `--split 1:1:1`
(clean 5/5/5) so the copy-paste path actually works. Verified against the
real loadBenchmark + splitBench: the exact shipped block parses 15 unique
tasks and splits 5/5/5 with sel>=5; the system's own error message confirms
"need ~50 total for 4:1:5".

Discoverability (Diataxis cross-linking):
  - README.md tutorials section: new entry (was zero skillopt mention)
  - docs/tutorials/README.md: added under ## Shipped
  - docs/guides/skillopt.md: "New to this? Start with the tutorial" callout

Every claim devex-verified against source: exit-code map from
skillopt.ts (accepted:0/no_improvement:1/aborted:2/errored:2), stderr
format from skillopt.ts:286-292, check ops from score.ts, output paths
from SKILL.md, split math from benchmark.ts.

* docs: regenerate llms-full.txt after skillopt tutorial + README edit

Refreshes the inlined doc bundle so the committed llms-full.txt matches
fresh `bun run build:llms` output (test/build-llms.test.ts drift guard).
Picks up the README tutorials-section edit from c39dbdb1. The new tutorial
file itself isn't curated into scripts/llms-config.ts (the bundle curates
a fixed doc set, not every tutorial) — this is purely the README delta.

* fix(ci): stop embed-preflight leaking gateway config into facts-backstop shard

CI shard 10 failed 5 `put_page facts backstop` tests with:

  [embed(openai:text-embedding-3-small)] Incorrect API key provided: sk-test

(captured by the diagnostic stderr added in a prior commit). Root cause is
a cross-file module-state leak, not a logic bug:

- `embed-preflight.test.ts` calls `configureGateway({env:{OPENAI_API_KEY:
  'sk-test'}})` to drive credential-validation scenarios. It resets the
  gateway `beforeEach` but never AFTER its last test, so it leaves the
  gateway configured with `sk-test`.
- bun runs every file in a shard inside ONE process. The residual config
  bleeds into the next file. When `facts-backstop-gating.test.ts` lands in
  the same shard, its put_page calls see `isAvailable('embedding') === true`
  (the key is *present*, just invalid), so put_page attempts a real embed
  and 401s before the backstop gating even runs.
- It's intermittent across master merges because shard bin-packing changes
  which files co-locate. (It "resolved" after the v107 merge earlier for
  exactly this reason, then came back.)

R1/R2 test-isolation lint doesn't catch this — it's `configureGateway`
module state, not `process.env` or `mock.module`.

Two fixes, both using the gateway's own `resetGateway()` seam (no
process.env, R-compliant):

1. embed-preflight.test.ts — `afterAll(() => resetGateway())` so the leaker
   cleans up after the whole file. Primary fix; also protects any OTHER
   shard-mate that reads gateway state.
2. facts-backstop-gating.test.ts — `beforeEach(() => resetGateway())` so the
   suite is deterministic regardless of ambient gateway config. Defense in
   depth: isAvailable('embedding') is now reliably false → put_page uses
   noEmbed → the import never embeds → only the backstop gating (the suite's
   actual subject) is exercised.

Verified: running leaker+victim in one process (the shard repro) goes
16/16; full shard 10 goes 1208/1208 (was 5 fail in CI). Typecheck clean.

* docs(skillopt): make benchmark authoring an agent job, not a human chore

The prior tutorial taught a human to hand-write a 15-task benchmark — but
nobody does that. The real workflow is: user says "make skill X better,"
the AGENT authors the benchmark and runs the optimizer. The agent-facing
dispatcher didn't actually cover that.

Gap found: skill-optimizer/SKILL.md documented exactly one authoring path,
`--bootstrap-from-routing`, which (a) requires a pre-existing
routing-eval.jsonl (bootstrap-benchmark.ts:57-63 refuses without it) and
(b) generates tasks from ROUTING fixtures — which test dispatch ("does
this phrasing pick this skill"), not output quality. So an agent told to
improve a skill with no benchmark had no documented way to author a
*quality* benchmark; it'd have to reinvent the JSONL format the human
tutorial teaches.

Two fixes:

1. skills/skill-optimizer/SKILL.md — new "Authoring the benchmark yourself
   (the common case)" section: read the target SKILL.md, generate ~15
   realistic tasks, attach rule judges (contains/max_chars/min_citations/
   section_present/regex/tool_called), write the JSONL, run with
   `--split 1:1:1` (the default 4:1:5 needs ~50 tasks). Decision-tree row
   "New skill, no benchmark" now says "Author one" instead of pointing at
   bootstrap-from-routing; the bootstrap row is reframed as a head-start
   that only applies when routing fixtures exist and notes routing tasks
   test dispatch, not quality.

2. docs/tutorials/improving-skills-with-skillopt.md — new "The easiest
   path: ask your agent" section up top. Tells humans to just tell their
   agent "improve my X skill — write a benchmark first," and frames the
   manual walkthrough as "read this when you want to understand or

* feat(skillopt): --bootstrap-from-skill starter benchmark generator

Generate a quality benchmark from a skill's SKILL.md directly, no
routing-eval.jsonl required. One LLM call emits JSONL tasks (each with rule
judges) that the agent reviews + strengthens before optimizing.

- runBootstrapFromSkill: JSONL output parsed line-by-line with skip-bad-line
  salvage (a truncated final line drops, the rest survive); a task is kept only
  when >=2 valid rule checks survive; provider errors propagate instead of
  collapsing to bootstrap_empty.
- --bootstrap-tasks N (default 15, cap 50); maxTokens scales with the count.
- Extracted assertBenchmarkAbsent + readSkillBodyOrThrow shared with the routing
  bootstrap; hardened runBootstrap's routing-eval parse to skip malformed lines.
- CLI: --bootstrap-from-skill short-circuit + 6-way mutual exclusion; parseFlags
  exported for unit tests. The benchmark-not-found hint + --help now point here.
- The generator's REVIEW line prints the paste-ready
  `--bootstrap-reviewed --split 1:1:1` next command (the default 4:1:5 split
  refuses a 15-task starter at D_sel >= 5).
- 20 hermetic cases incl. round-trip into loadBenchmark + splitBench(1:1:1).

* docs(skillopt): make --bootstrap-from-skill the primary no-benchmark path

The agent runs --bootstrap-from-skill, strengthens the generated judges (they
are weak drafts), deletes the sentinel, then runs --bootstrap-reviewed
--split 1:1:1. Freehand authoring is demoted to the fallback for the rare skill
the generator can't draft well. Updates the Iron Law, decision tree, and
anti-patterns to cover both bootstrap modes and the 15-task / --split 1:1:1
gotcha.

* chore(release): v0.42.1.0 --bootstrap-from-skill

VERSION + package.json -> 0.42.1.0, CHANGELOG entry, CLAUDE.md skillopt
annotation, regenerated llms-full.txt.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs: surface --bootstrap-from-skill in README + skillopt reference

- docs/guides/skillopt.md: 30-second pitch leads with --bootstrap-from-skill;
  flag table adds --bootstrap-from-skill + --bootstrap-tasks rows.
- README.md: skillopt tutorial pointer mentions generating a starter benchmark.
- Regenerated llms-full.txt (README is in the bundle).

* fix(ci): bump FULL_SIZE_BUDGET 700KB→750KB for legitimate CLAUDE.md growth

The skillopt wave annotations + merged v0.41.34-36 master releases pushed
llms-full.txt to 700,423 bytes — 423 over the 700KB cap — failing the
build-llms size-budget test on CI shard 6. CLAUDE.md is ~540KB (77% of the
bundle) and is the whole point of the one-fetch artifact, so it stays inlined;
the budget tracks its per-release growth. 750KB still fits 200k+ context models.

cd8efee0ea v0.41.15.0 feat(sync): --timeout + --max-age + partial status (closes #1472 RFC) (#1506)
* feat(sync): migration v98 last_refreshed_at + deleteLockRowIfStale helper

Schema foundation for v0.41.15.0's `gbrain sync --break-lock --max-age <s>`
flag. Adds `gbrain_cycle_locks.last_refreshed_at TIMESTAMPTZ` as the
heartbeat signal that distinguishes wedged-but-alive lock holders from
healthy long-running syncs that are actively refreshing.

Why last_refreshed_at not acquired_at: `withRefreshingLock` already bumps
`ttl_expires_at` every ~5 min while work runs, but leaves `acquired_at` at
the original timestamp. A 35-min media-corpus sync that's healthy has
`acquired_at` 35 min ago but `last_refreshed_at` 30 seconds ago. Using
acquired_at for --max-age would steal healthy locks; last_refreshed_at
correctly identifies only holders whose JS interval has stopped firing.

D-V4-1 rollout safety: migration v98 backfills `last_refreshed_at = NOW()`
(NOT `= acquired_at`) so pre-upgrade holders running the old binary get a
30-min protection window. After that window all pre-upgrade syncs are
either complete (lock released) OR genuinely wedged (--max-age does the
right thing). Documented as a known caveat in CHANGELOG.

D-V4-mech-4 SQL cast: deleteLockRowIfStale uses `$N * INTERVAL '1 second'`
not `$N::interval` (Postgres does not cast integer to interval the latter
way). Atomic DELETE keyed on (id, holder_pid, last_refreshed_at < NOW() -
$N * INTERVAL '1 second') RETURNING id, last_refreshed_at — no TOCTOU
between inspect + delete.

D-V4-mech-3 schema-snapshot parity: column added to all 3 snapshots so
fresh init paths (pglite-schema.ts, schema.sql) initialize correctly
without depending on the migration runner. schema-embedded.ts regenerated
via `bun run build:schema`.

Pinned by 13 PGLite cases in test/sync-break-lock-all.test.ts:
tryAcquireDbLock writes on INSERT, withRefreshingLock refresh bumps both
columns, inspectLock surfaces the new field, deleteLockRowIfStale refuses
fresh / breaks stale / safe on holder_pid mismatch / refuses NULL
(pre-v98). R1 + R6 regression invariants from the v4 plan.

Closes #1472 (RFC from @garrytan-agents) — schema foundation only;
performSync abort threading + CLI flags + consumer threading land in
follow-up commits in this PR.

* feat(sync): --timeout + --max-age + partial status + per-source AbortController

The CLI surface for v0.41.15.0. Wires `gbrain sync --timeout <s>` (graceful
self-termination) and `gbrain sync --break-lock --all --max-age <s>`
(cron-self-heal) end-to-end through `performSync`, `runOne`, `runBreakLock`,
and all `SyncResult.status` consumers.

Surface 1: `gbrain sync --timeout <s>`
  - New `SyncOpts.signal?: AbortSignal` threads through `performSync` →
    `withRefreshingLock` work callback → `performSyncInner`.
  - D-V3-1 honest scope: abort checks fire ONLY in pre-bookmark phases
    (pull, delete, rename, import). Extract + embed run to completion if
    reached. The `last_commit` bookmark write at sync.ts:1261 is the
    invariant boundary — partial CANNOT advance the bookmark because the
    abort checkpoints sit strictly before that write.
  - D-V3-2 per-iteration: abort check at top of every loop iteration
    (delete, rename, serial import, each parallel worker's while loop)
    matches the per-file granularity the existing loops already have.
  - D-V3-3 per-source AbortController: `--timeout --all` creates ONE
    controller inside runOne per source so each gets its own budget;
    NOT a shared global controller (which would starve later sources).
    try/finally + timer.unref() guarantees cleanup on throw.
  - D-V4-mech-7 pull error.cause: pullRepo wraps execFileSync errors in
    GitOperationError. The catch inspects e.cause.code === 'ETIMEDOUT'
    and e.cause.signal === 'SIGTERM' (NOT the top-level error) to
    distinguish timeout (partial reason='pull_timeout') from ordinary
    pull failure (existing warn-and-continue, R2 invariant preserved).

Surface 2: `gbrain sync --break-lock [--all] [--max-age <s>]`
  - Drops the --all refusal at sync.ts:1610. When combined with --all,
    runBreakLock iterates every active source and prints per-source verdict.
  - --max-age routes through the new deleteLockRowIfStale helper from
    db-lock.ts (atomic age-gated DELETE; no TOCTOU). Healthy refreshing
    holders survive by construction; only wedged-but-alive holders trip.

D-V3-5 partial-status consumer threading (conservative posture matching
blocked_by_failures):
  - printSyncResult: new `case 'partial':` arm reports filesImported +
    reason; tells operator to re-run to continue.
  - manageGitignore (both single-source and parallel runOne sites,
    plus watch mode): excludes partial from the gate. A partial sync's
    db_only path set isn't fully reconciled.
  - Auto-embed-backfill enqueue inside runOne: excludes partial. The
    next clean sync will re-walk and re-decide.

CLI flag parsing (T16):
  - parseDurationSeconds in sync-concurrency.ts: accepts 60s/10m/1h/bare
    int; rejects 0/negatives/decimals/garbage. Names the failing flag in
    the error message.
  - --timeout requires --source OR --all (validation rejects bare
    `gbrain sync --timeout`).
  - --max-age requires --break-lock; mutually exclusive with
    --force-break-lock.

Coverage:
  - 15 unit cases (test/sync-timeout.test.ts) pin parseDurationSeconds +
    SyncResult union additivity.
  - 2 E2E cases (test/e2e/sync-parallel.test.ts) pin the abort-mid-import
    contract against real Postgres: status='partial', last_commit
    unchanged, filesImported bounded.

Closes #1472 (RFC from @garrytan-agents) — CLI surface; schema foundation
landed in the previous commit.

* test(heavy): sync_timeout_rescue.sh reproducer for the cron-cascade

10K-page seed × 4 sources × deliberately tight --timeout × 3 sequential
cron emulations. Asserts every source reaches `last_commit === HEAD`
within 3 waves. Proves the v0.41.15.0 fix breaks the cascade the
PR #1472 RFC documented.

Workload (tests/heavy/_sync_timeout_rescue_workload.ts) is PGLite-only
because the PGLite engine forces serial sync internally (parallelEligible
excludes it). The parallel-fan-out + per-source AbortController case
lives in test/e2e/sync-parallel.test.ts against real Postgres. This
heavy test pins the contract that matters for cron: aborts → partial
returns → next wave content_hash-short-circuits + makes new progress.

Smoke-tested locally at PAGES=50 WAVES=2 TIMEOUT_SECONDS=2: every
source converges within 2 waves.

* docs(v0.41.15.0): CHANGELOG + README + TODOS + version bump

Bumps VERSION + package.json to 0.41.15.0 (next slot after master's
v0.41.14.0). CHANGELOG entry leads ELI10 per gstack voice rules and
documents the 3 intentional honest gaps:
  1. --timeout covers pull + delete + rename + import only; extract +
     embed run to completion (D-V3-1 honest scope).
  2. First 30 min after migration v98, --max-age cannot identify wedged
     pre-upgrade holders (D-V4-1 rollout trade-off).
  3. Full-sync triggers (first sync, --full, chunker-version rewalk)
     don't respect --timeout yet (deferred to v0.42+).

README troubleshooting section: paste-ready cron pattern with shell
timeout(1) for OS-level process isolation + gbrain's --timeout for
graceful self-termination half-a-minute earlier.

TODOS.md: v0.42+ entries for subprocess fan-out (revisit if shell
timeout(1) proves insufficient), full-sync --timeout coverage via
AbortSignal in runImport, and runFactsBackstop microtask-queue
process-alive caveat.

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

Closes #1472 (RFC from @garrytan-agents). Credit to @garrytan-agents
in the CHANGELOG for surfacing the production cron-failure data that
motivated the work.

* fix(test-isolation): rewrite JSDoc to not match mock.module() lint regex

scripts/check-test-isolation.sh greps for the literal string `mock.module(`
to flag top-level module mocks (R2 rule — top-level mocks leak across files
in the shard process). The regex doesn't know about comments, so my two new
test files tripped the lint with JSDoc lines literally describing the rule:

  test/sync-timeout.test.ts:11   "* `mock.module()` (R2). Engine ..."
  test/sync-break-lock-all.test.ts:15  "* mock.module(), no process.env ..."

Both files had ZERO actual mock.module() calls — only the comment text
matched. Rewrote both JSDocs to refer to "top-level module mocks" instead
of the literal token. Same meaning; doesn't trip the regex.

`bun run check:test-isolation` now passes (714 non-serial unit files
scanned). `bun run verify` clean (22/22 checks pass).

3de06b6c29 v0.38.2.0 fix(doctor): bounded frontmatter scan + partial-state surfacing (supersedes #1287) (#1297)
* fix(frontmatter): prune vendor dirs at descent + bounded wall-clock with partial-state surfacing

Two production-grade fixes for the v0.38.2.0 wave (supersedes PR #1287).

Root cause Fix 1 (the bug that hung gbrain doctor on 216K-page brains): both
brain-writer.ts:walkDir and frontmatter.ts:collectFiles recursed into every
subdirectory without calling pruneDir, the canonical descent-time pruner
used by sync/extract/transcript-discovery since v0.35.5.0. On brains that
double as code workspaces, the walkers stat'd hundreds of thousands of
entries under node_modules / .git / .obsidian / *.raw / ops that isSyncable
filtered out at the leaf — paying the IO cost for nothing. Wiring pruneDir
at descent (with the v0.37.7.0 #1169 submodule-gitfile check) eliminates
the bulk of the wall-clock pain.

Fix 2 (codex outside-voice C1): AbortSignal.timeout cannot interrupt the
synchronous walker — readdirSync / lstatSync / readFileSync block the event
loop, so timer callbacks never fire mid-walk. The load-bearing wall-clock
bound is now a deadline check inside scanOneSource's visit callback
(Date.now() > opts.deadline). AbortSignal still works at source boundaries.

Shape changes (codex C2 + C4):
- ScanOpts: + deadline?: number, + dbPageCountForSource hook, + visitDir test seam
- PerSourceReport: + status: 'scanned' | 'partial' | 'skipped', + files_scanned, + db_page_count
- AuditReport: + partial: boolean, + aborted_at_source: string | null
- ok = grandTotal === 0 && !partial (a clean prefix from a timed-out scan
  no longer falsely reports clean)

walkDir + collectFiles now exported with an optional visitDir callback for
the regression suite. Production callers don't pass it.

Tests:
- test/brain-writer-walk-prune.test.ts (new, 12 cases): visitDir-based
  descent-time pruning assertions for both walkers. Pins the property
  output-based tests can't catch (isSyncable rejects vendor files at
  the leaf — so a test checking only output passes under the original bug).
- test/brain-writer-partial-scan.test.ts (new, 5 cases): deadline + partial
  state + ok-after-abort + numerator/denominator coverage. Uses deadline,
  NOT AbortSignal, since codex C1 proved abort can't interrupt sync.
- test/brain-writer.test.ts: existing "abort mid-scan" test refit to the
  new partial-state contract (per_source has 'skipped' entries instead of
  being empty — gives doctor visibility into which sources weren't checked).
- test/migrations-v0_22_4.test.ts: AuditReport fixture extended with the
  new required fields.

* fix(doctor): wire deadline + partial-state into frontmatter_integrity check

Adopts the v0.38.2.0 ScanBrainSources surface in doctor's frontmatter_integrity
check.

- AbortSignal.timeout(fmTimeoutMs) for between-source bound.
- deadline = Date.now() + fmTimeoutMs (the load-bearing mid-walk bound —
  codex C1 caught that AbortSignal alone can't fire inside the sync walker).
- GBRAIN_DOCTOR_FM_TIMEOUT_MS env override (default 30000ms; invalid values
  fall back to default rather than crash).
- Per-source DB denominator via SELECT COUNT(*) FROM pages WHERE source_id = $1
  AND deleted_at IS NULL (codex C3: deleted_at filter so soft-deleted pages
  don't inflate the count).
- Honest partial-render: "PARTIAL — scanned ~N files (source has ~M pages in
  DB), K issue(s) so far" instead of "scanned ~N of M pages" (codex C3 — the
  two populations are overlapping but not identical sets).
- "NOT SCANNED (timeout — run gbrain frontmatter validate <id>)" per skipped
  source so the user knows which sources didn't get checked.
- Catch block simplified to "unexpected error only" (codex D4 — the
  AbortError special case from PR #1287 was unreachable in a sync walker).

Tests: test/doctor-frontmatter-partial.test.ts (new, 11 cases) — structural
source-grep pins on every load-bearing render string plus the simplified-
catch contract. Behavioral coverage is deferred to the heavy script
(tests/heavy/frontmatter_scan_wallclock.sh, T6) because runDoctor calls
process.exit unconditionally and can't be driven from bun:test directly;
refactoring runDoctor to return rather than exit is a separate TODO.

* docs: v0.38.2.0 release notes, Phase 2 design sketch, heavy wall-clock smoke

- CHANGELOG.md: ELI10-lead-first release entry per CLAUDE.md voice rules.
  Names the user-visible behavior change, the per-source partial render, the
  performance numbers table, the "things to watch" caveats. Credits
  @garrytan-agents for PR #1287's diagnosis.
- VERSION + package.json: 0.37.11.0 -> 0.38.2.0.
- docs/architecture/frontmatter-scan-incremental.md: Phase 2 design sketch
  for DB-backed scan state. Schema, migration shape, writer paths
  (sync-side UPSERT + incremental scan + autopilot cycle phase), doctor
  reader, sequencing concerns, two-phase rollout plan. Starting point for
  the follow-up PR — sub-second steady-state doctor needs incremental
  state, but the schema migration carries its own contract surface
  (forward-reference bootstrap, schema-drift E2E, PGLite-vs-Postgres
  parity) that deserves its own focused PR.
- tests/heavy/frontmatter_scan_wallclock.sh (new, manual / nightly per
  tests/heavy/README.md): seeds a synthetic 60K-file brain (10K real + 50K
  under node_modules/) and asserts gbrain doctor completes in <15s with
  frontmatter_integrity: ok. Codex C7 caught that the original plan's
  1500-file budget was too small to be a meaningful guard — at that scale
  the test passes BEFORE AND AFTER the fix, proving nothing. 60K is the
  minimum that catches the descent-into-vendor-trees regression.

* fix: adversarial review followups — CLI hint, deadline-vs-await race, between-source breadcrumb

Codex adversarial review caught 4 real bugs in the v0.38.2.0 wave. All four
fixed before ship.

#1 (user-facing): `gbrain frontmatter validate` takes a filesystem PATH, not a
source id. Pre-fix the NOT SCANNED hint pointed users at
`gbrain frontmatter validate src-a` — which would fail with "no such
directory", breaking the very remediation this PR ships to give them. Fix:
render `src.source_path` instead.

#2 (correctness): between sources, `await dbPageCountForSource(src.id)` ran
unchecked. A slow query could blow past the deadline, then scanOneSource was
still called and returned `status='partial'` with `files_scanned=0` —
misleading ("partial scan" when actually zero files were scanned). Fix: add a
post-await deadline re-check; mark source + remainder as 'skipped' if the
budget already burned.

#3 (UX): when the outer-loop deadline check fired BETWEEN sources,
`aborted_at_source` stayed null and the doctor message said "PARTIAL SCAN"
with no source name. Fix: stamp `aborted_at_source` with the source we were
about to start.

#4 (correctness): the COUNT query had no per-call deadline. A wedged
Postgres pool could make a single COUNT hang past the budget and defeat the
wall-clock guarantee. Fix: Promise.race against the remaining deadline; on
timeout, resolve null and the post-await re-check (#2) marks the source
skipped.

Tests: 3 new regression cases in brain-writer-partial-scan.test.ts pinning
the fixed contracts (skipped-vs-partial under slow COUNT, hanging COUNT
within deadline, aborted_at_source before any source starts). 8648 pass /
0 fail across the full suite.

* docs(README): refresh production-brain stats — 8.2x pages, 5.6x people, 7.4x companies

Pre-update line (months stale): "17,888 pages, 4,383 people, 723 companies, 21
cron jobs running autonomously, built in 12 days."

Fresh counts from ~/git/brain (the wintermute production brain):
- pages: 17,888 → 146,646 (8.2x)
- people: 4,383 → 24,585 (5.6x)
- companies: 723 → 5,339 (7.4x)
- cron jobs running: 21 → 66 (113 total, 66 enabled per ~/git/wintermute/workspace/ops/cron-snapshot.json)

Dropped "built in 12 days" — at 146K pages the initial-velocity claim is
stale narrative that no longer matches the current scale story.

9a3ef3cda7 feat: pgGraph-inspired CI scaffolding wave (v0.37.4.0) (#1228)
Schema-migration matrix + fuzz harness + RSS budget gate + read-latency
under sync + sync lock regression + tests/heavy convention + nightly CI
workflow + BFS frontier cap on traverseGraph.

CI infra (T1-T7):
- tests/heavy/ directory convention + scripts/run-heavy.sh + bun run test:heavy
- tests/heavy/pg_upgrade_matrix.sh: walk pre-v0.13 + pre-v0.18 brain shapes
  forward to head via bootstrap → SCHEMA_SQL → migrations → verifySchema
- test/fuzz/{pure,mixed,filesystem}-validators.test.ts: 1000-run fast-check
  property tests across 8 trust-boundary validators
- scripts/check-fuzz-purity.sh: bun-bundle + grep guard, wired into verify
- tests/heavy/measure_rss.sh: in-memory PGLite workload + peak RSS measurement
  via /proc/self/status (Linux) or process.memoryUsage().rss fallback (macOS,
  refuses to write baseline)
- tests/heavy/read_latency_under_sync.sh: phase A baseline + phase B under
  parallel writer load, reports p50/p95/p99 + delta_pct
- tests/heavy/sync_lock_regression.sh: N concurrent gbrain sync against one
  DB, asserts 1 winner + N-1 lock-busy + zero leaked gbrain_cycle_locks rows
- .github/workflows/heavy-tests.yml: cron '17 8 * * *' + heavy-tests label
  trigger + Postgres service + artifact upload on failure

Engine (T8):
- BrainEngine.traverseGraph opts gain frontierCap?: number + onTruncation?:
  (info: TruncationInfo) => void callback. Return shape preserved
  (Promise<GraphNode[]>) for MCP wire stability.
- Postgres CTE: parenthesized LIMIT N ORDER BY (slug, id) inside recursive term.
- PGLite: same SQL with positional params.
- Per-call callback closure — not engine-instance state — so concurrent
  traversals on the same engine don't cross-talk. 5 contracts pinned in
  test/regressions/v0_36_frontier_cap.test.ts.

Three plan-review passes ran before any code: CEO scope review (Approach C),
Eng dual-voice review (Claude subagent + Codex), and Codex 2nd-pass against
the revised plan. The 2nd pass caught issues the first two missed (Bun ESM
vs require.cache; engine-instance metadata stomping under concurrency;
fixture-size inconsistency). All addressed.
