User flagged that the bureau was emitting English-only output, violating
the project's bilingual rule. Every narrative field now ships in both
languages: stored in sibling DB columns + rendered as adjacent markdown
sections per CLAUDE.md §3.
Migration 0007 (apply as supabase_admin):
- public.hypotheses +question_pt_br, +position_pt_br,
+argument_for_pt_br, +argument_against_pt_br
- public.contradictions +topic_pt_br, +notes_pt_br
- public.witnesses +access_to_event_pt_br, +bias_notes_pt_br,
+verdict_pt_br
- public.gaps +description_pt_br, +suggested_next_move_pt_br
- public.evidence: unchanged (verbatim_excerpt stays source-language)
- JSONB siblings inside contradictions.chunks + gaps.scope handled at
runtime (statement_pt_br, title_pt_br, dominant_model_pt_br,
why_surprising_pt_br, what_it_implies_pt_br).
Detective prompts (all 7) rewritten with explicit bilingual JSON contract:
- Output protocol section names every EN field + its _pt_br sibling
- "Bilingual is mandatory" warning in the task instruction
- Sentinel skip-states unchanged (NO_HYPOTHESES, NO_CONTRADICTIONS,
INSUFFICIENT_TESTIMONY, INSUFFICIENT_HYPOTHESIS, NO_OUTLIERS,
NO_NEW_EVIDENCE, INSUFFICIENT_ARTEFACTS)
- Schneier: parallel arrays — hidden_assumptions[i] matches
hidden_assumptions_pt_br[i], lengths must match
- Case-Writer: interleaved §1 (EN) / §1 (PT-BR) per act in the body
Writer-side validation (all 7 tools):
- Reject INSERT if PT-BR sibling missing when EN field is set
- Persist both languages atomically in one INSERT (no half-updates)
- Markdown renderers write adjacent EN+PT-BR sections in case files
(## Argument for (EN) followed by ## Argumento a favor (PT-BR), etc.)
Detective parse layer (all 7 detectives):
- Coerce both keys from JSON output
- "incomplete_bilingual_*" skip reason when either side missing
- Defensive: PT-BR fields trimmed + length-capped same as EN
Orchestrator propagates question_pt_br + topic_pt_br through job payload
to runHolmes / runCaseWriter, mirroring the chat-tool entry point.
Web (UI):
- /api/jobs/[id] hydrates _pt_br siblings from pg
- job-status-poller HypothesisCard: PT-BR primary, EN in <details>
fallback when both exist
- ContradictionCard: PT-BR statement primary + secondary EN quote
- WitnessCard: PT-BR verdict primary + secondary EN quote, panels in PT
- GapCard: PT-BR title/why/implies primary
- /bureau hub: SELECTs both columns, renders PT-BR primary
- /h/[id]: ArgumentPanel renders PT-BR primary with collapsible EN
fallback when both exist
- BureauSnapshot homepage: position_pt_br / topic_pt_br / verdict_pt_br
primary
- DocBureauPanel /d/[doc]: same primary-PT-BR pattern
- New web/lib/i18n/pick.ts helper (unused yet by chat/agents — kept
for future locale-driven switching when both languages are equally
full; current rule is PT-BR-first since the user is brasileiro)

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.
