Luiz Gustavo	4d4c02a8e1	W3.5: Holmes hypothesis tournament detective ... Adds the second AI detective in the Investigation Bureau runtime: Sherlock Holmes, who builds 2-3 rival hypotheses with calibrated priors + posteriors against a corpus shortlist. Pipeline: 1. hybridSearch() grounds Holmes with 8-15 chunks via the same hybrid_search_chunks RPC the web uses (BM25 + dense + RRF). Default max_dense_dist=0.55 (runtime favors recall over precision; web's /api/search/hybrid stays at 0.40 for chat). 2. claude-sonnet-4-6 emits a strict JSON array with position + argument_for + argument_against + prior + posterior + confidence_band + evidence_refs. Citations use [[doc-id/pNNN#cNNNN]] wiki-links. 3. writeHypothesis() validates posterior ∈ [0,1], auto-corrects the Tetlock band from the posterior (high ≥0.90, medium 0.60-0.89, low 0.30-0.59, speculation <0.30), checks evidence_refs FK against public.evidence, INSERTs into public.hypotheses + writes case/hypotheses/H-NNNN.md. Discipline guarantees (prompts/holmes.md): - posteriors across rivals sum to ≈1.0 - no claim without chunk citation - prefer lower band when ambiguous (anti-inflation) - declarative one-sentence position, no hedging - emit `NO_HYPOTHESES` when corpus is silent (refuses to fabricate) Smoke test (Sandia green fireballs 1948-49): - H-0001 prior 0.5 → posterior 0.2 (speculation): natural meteoric - H-0002 prior 0.3 → posterior 0.4 (low): classified weapons / tests - H-0003 prior 0.2 → posterior 0.4 (low): genuinely unidentified Bayesian update visible: "natural meteoric" prior dropped 60%; both rivals climbed. 4 unique chunk citations across the 3 hypotheses. orchestrator dispatches `hypothesis_tournament` kind via runHolmes; job marked `failed` if all rivals error, `complete` otherwise.

Luiz Gustavo	189a771cbe	W3.1-W3.4: Investigation Bureau foundation — migrations, runtime, Locard ... Migrations: - 0004_investigation_bureau.sql: 7 new tables (investigation_jobs + evidence, hypotheses, contradictions, witnesses, gaps, residual_uncertainties), id sequences, pg_notify trigger on investigation_jobs, RLS read-only public, investigator role with least-privilege grants (no service_role). - 0005_investigator_write_policies.sql: fixup adding RLS INSERT/UPDATE policies bound to investigator + service_role + postgres (RLS with only a SELECT policy was silently blocking the worker's claim UPDATE). investigator-runtime/ (new Bun + TS container): - src/main.ts: LISTEN/NOTIFY poller, claim-with-SKIP-LOCKED, drain pool, healthcheck file, graceful SIGTERM shutdown. - src/orchestrator.ts: chief-detective dispatch (evidence_chain → Locard). Marks job failed when all per-item outputs error; surfaces first errors. - src/lib/{env,pg,audit,ids,claude}.ts: typed config (gate #8), pool + dedicated LISTEN client, NDJSON audit, sequence allocator (E-NNNN etc), claude -p subprocess with quota detection (api_error_status=429). - src/tools/write_evidence.ts: schema-validate (grade A/B/C custody steps), resolve chunk_pk via FK, verify verbatim_excerpt actually appears in chunk content, INSERT + render case/evidence/E-NNNN.md + audit. - src/detectives/locard.ts: load chunk → call Claude with locard.md system prompt → parse strict JSON → call writeEvidence locally. - Dockerfile installs `claude` CLI (OAuth) at build time. Compose: - new `investigator` service builds from investigator-runtime/, connects with low-privilege role, mounts case/ RW and wiki/+raw/ RO, 512m mem cap. Web: - /api/admin/investigate/test (POST+GET) gated by middleware (W0-F1). POST creates a job, GET polls status. For W3.6 it becomes the chat tool. End-to-end smoke: INSERT job → pg_notify → claim → Locard dispatch → claude subprocess invoked. Auth works (CLI v2.1.150). Currently quota exhausted (weekly limit · resets 3pm UTC) — pipeline catches the typed isQuota error, marks job failed with surfaced reason. Architecture proven; quota reset enables real evidence creation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-23 19:49:33 -03:00
