Fix-wave series baselines (W0 → W9)

Recorded per wave so the series' "10x better for 2x effort" claim is measured, not vibed (fix-wave plan D4.13). Update this file in each wave's PR; keep the prior rows — the deltas ARE the receipt.

Retrieval-quality canary (MANDATORY before W1, and after W1/W3/W9): run gbrain eval gate against a NON-PRODUCTION brain (the production PGLite brain is single-writer and usually held by a live gbrain serve; eval runs never touch ~/.gbrain per the eval discipline — results land in <repo>/.gbrain-evals/eval-results.jsonl). Record the gate verdict + headline metrics here per run.

Containment sprint (2026-08-15, v0.46.9.1, branch garrytan/containment-sprint-coverage-modularity)

God-file line counts AFTER the façade peels. Five of the six giants (all but migrate.ts) were peeled into focused module dirs; the peeled lines live in the sibling dirs listed below the table (count both when comparing against W0 — the façade number alone is not the receipt).

File	Lines
src/commands/doctor.ts	4,177
src/core/operations.ts	303
src/core/pglite-engine.ts	5,546
src/core/postgres-engine.ts	5,704
src/core/migrate.ts	6,320
src/commands/sync.ts	4,120
src/core/ai/gateway.ts	4,049
src/cli.ts	3,323
src/core/cycle.ts	2,933
src/core/search/hybrid.ts	2,453
src/core/engine.ts	2,343
src/core/search/mode.ts	1,232

Peeled module dirs (where the moved lines live): src/core/ops/* 7,759; src/commands/doctor/checks/* 4,944 + four tail modules 1,321; src/core/sync-{anchor,cost-gate,git,lock,reconcile,status-report}.ts 2,030; src/core/{pglite,postgres}-engine/* 3,505. Every façade re-exports its full prior surface.

Guards: 50 scripts/check-* files; 4 self-tested (harness 0s, budget 30s). Regrowth is now ratcheted: check:module-size (in bun run verify) pins per-file ceilings in scripts/module-size-limits.tsv — growth, stale slack, and unlisted >1,500-line src files all fail.

Test infra: merged lcov coverage on every PR run (advisory), diff-coverage gate report-only at 80%, corpus-matched baseline gate vs origin/master's committed baseline, nightly unit+serial+E2E coverage-full pipeline; behavioral-vs-structural suite classification (scripts/classify-tests.ts) splits the headline test count.

Retrieval canary: NOT RUN in this PR (structural refactor; behavior pinned by the engine-parity suite, now in CI on every PR and master push). The W1/W3/W9 canary mandate is unchanged.

W0 (2026-08-14, branch garrytan/code-smell-fix-wave @ post-hotfix)

God-file line counts (the audit's structural targets, BEFORE the registry waves):

File	Lines
src/commands/doctor.ts	10,057
src/core/operations.ts	7,459
src/core/pglite-engine.ts	6,874
src/core/postgres-engine.ts	6,847

src/core/cycle.ts	2,933
src/core/search/hybrid.ts	2,453
src/core/engine.ts	2,320
src/core/search/mode.ts	1,232

Guards: 47 scripts/check-* files; 3 self-tested (harness <1s, budget 30s); single registry established (guards-manifest.tsv; check:all deleted; 3 previously-unreachable guards wired into verify).

Test infra: PGLite snapshot default-on for bun run test. Per-PGLite-file: 1.63s cold → 0.91s snapshotted (measured on test/db-lock-fencing.test.ts). Full-suite wall-clock (post-snapshot): recorded in the W0 ship notes — see the run banner of the W0 PR's bun run test evidence.

Retrieval canary: PASS @ f2b40f7ef (hermetic deterministic-embedder CLI run; recall@10=1.0000 first_relevant=1.0000 expected_top1=0.8333 vs floors 0.70/0.60/0.50; run bun run scripts/run-eval-canary.ts to reproduce, ledger: .gbrain-evals/eval-results.jsonl). Honest scope: the canary gates the hybrid ranking pipeline (keyword/title/alias arms + RRF against gold qrels) with synthetic basis vectors — no API keys, no production brain, so the live-serve lock is moot. Semantic-embedding regressions remain the keyed eval suites' job. Wired into bun run verify as check:eval-canary.

Verified-bug status at W0 ship: cycle-lock refresh + fencing (TODO-OPS-2 closed), stall-death parent unblock, started_at ×4, modality carry, import typed aborts, lint single-pass, prompt EOF safety, guard self-test harness, snapshot default-on. W0a superseded by master's WP1/D7 (port-ledger in the plan file).
