User: "shouldn't mention the names of the mind-clones, should merge all
analyses and write like a best-seller author would, about what happened."
Voice rewrite (prompts/case-writer.md):
- Reference voices: Erik Larson, Sam Kean, John McPhee, Mark Bowden.
Plainspoken non-fiction, scene-driven, fascinated.
- One narrator. NEVER say "Sherlock Holmes argues" / "Sun-Tzu builds
the case" / "the team concluded". No internal-process names reach
the reader.
- Hook the first paragraph. Open in a scene with a date, place, and
person doing something specific. NOT "This case investigates..."
- Show, don't argue. Verbatim quotes stay source-language in
blockquotes; the narration around them is the narrator's voice.
- Every claim cites a chunk with [[doc-id/pNNN#cNNNN]].
- Forbidden ceremony: "In summary…", "Em suma…", "Ultimately…",
"It is worth noting…", detective names, probability tables,
hypothesis tournaments.
- The honest unknown is the subject, not a failure: "Whatever was in
the sky over Sandia in December 1948, the government never said."
- 4-6 numbered scenes, each title-cased specifically ("The Green
Sphere Over Highway 60" not "Background").
- Bilingual EN + PT-BR per CLAUDE.md §3 — sections alternate, no
mid-paragraph language mixing.
- Refusal: emit INSUFFICIENT_ARTEFACTS rather than padding when the
corpus is thin.
Raw-material pipeline (src/detectives/case_writer.ts):
- hybridSearch(topic, lang, top_k=18) gives the narrator real corpus
scenes with verbatim text + chunk_id citations + bbox metadata.
This is what was missing — v1 only saw pre-digested hypothesis
artefacts, which is how the academic prose got there.
- Dropped the hypotheses + contradictions queries from the loader.
They were skeptic-framing scaffolding that doesn't belong in the
raw material a best-seller narrator works from.
- New buildPrompt sections: "Primary-source scenes", "Curated
verbatim quotes", "Anomalies and surprises", "Named witnesses".
Anomalies (Taleb's outlier gaps) reframed: drop dominant_model
skeptic baseline, keep title + why_surprising as gold material.
- Refusal floor: < 4 scenes from hybridSearch → skip with reason.

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)

Brings the bureau from 4 → 8 detectives. All eight run as Bun + claude-CLI
subprocesses against the same Supabase + investigation_jobs LISTEN/NOTIFY
queue, sharing search.ts hybridSearch and writer-side validators that
gate writes against schema + FK.
New detectives:
Poirot (witness_analysis)
- prompts/poirot.md — credibility / access / bias / corroboration /
verdict; uses entity_mentions JOIN chunks to pull 12 chunks per
person; resolves corroboration_refs chunk_ids defensively (accepts
bare cNNNN even when the model emits pNNN/cNNNN).
- INSERT into public.witnesses with W-NNNN naming.
- Tone: purple (#9b5de5).
Taleb (outlier_scan)
- prompts/taleb.md — "surprise is relative to a model"; at most 3
outliers; each requires explicit dominant_model + why_surprising +
what_it_implies; fan-out into public.gaps with scope.kind="outlier".
- Same unscoped-fallback as Dupin (Pass 1 with doc_id, Pass 2 widens
to corpus if hits < 3).
- Tone: yellow (#ffd23f).
Tetlock (calibrate_hypothesis)
- prompts/tetlock.md — honest Bayesian update; emits new_posterior +
Δ + recommended_action ∈ {keep, downgrade, upgrade, supersede}.
- write_calibration UPDATEs public.hypotheses + APPENDS a
"## Calibration history" section to the H-NNNN.md case file
(calibration is append-only — each datapoint matters). Posterior
band auto-corrected to match Tetlock thresholds.
- NO_NEW_EVIDENCE sentinel handled; pure 'keep' with |Δ|<0.005 only
touches updated_at + reviewed_by.
- Tone: teal (#26d4cc).
Case-Writer (case_report)
- prompts/case-writer.md — Dr. Watson assembles all artefacts
(E-NNNN, H-NNNN, R-NNNN, W-NNNN, G-NNNN) into a five-act narrative.
ILIKE filter on topic; doc_id optional scope.
- Larger budget cap (≥ $0.50) + longer timeout for prose generation.
- Writes case/reports/<slug>.md with frontmatter (topic + counts);
no DB table for v0.
- New page /c/[slug] renders the report via MarkdownBody + stat chips.
- Tone: gold (#e0c080).
Hardening across the bureau:
- Sentinel parsing now accepts backticked AND prose-trailing forms
(Holmes NO_HYPOTHESES, Dupin NO_CONTRADICTIONS, Schneier
INSUFFICIENT_HYPOTHESIS, Poirot INSUFFICIENT_TESTIMONY, Taleb
NO_OUTLIERS, Tetlock NO_NEW_EVIDENCE, Case-Writer
INSUFFICIENT_ARTEFACTS). Avoids the failure mode where the model
refuses honestly but the runtime treated it as a parse error
(observed live with Poirot+Hoover identifying the DIRECTOR
false-positive disambiguation issue in entity_mentions).
Chat tool extensions (web/lib/chat/tools.ts):
- request_investigation now accepts 7 kinds. Each routes to its
detective with appropriate validation (hypothesis_id regex,
person_id kebab-case, topic non-empty, doc_id for evidence_chain).
- ETA per kind: Holmes/Dupin 60s, Poirot 45s, Schneier/Tetlock 30s,
Taleb 50s, Case-Writer 180s (longer prose), Locard 30×n_chunks.
UI integration:
- chat-bubble inline card paints each detective in its tone color.
- /jobs/[id] page header swaps name/subtitle/tone per detective;
question label adapts ("Topic" / "Hypothesis under attack" /
"Witness under analysis" / "Topic to outlier-scan" / "Hypothesis
under recalibration" / "Case to assemble").
- job-status-poller renders: case-report link card (gold), outlier
cards (yellow), witness cards (purple) — alongside existing
hypothesis, evidence, contradiction cards.
- /api/jobs/[id] hydrates witnesses (JOIN entities for canonical_name)
+ gaps (with scope JSONB).
- /c/[slug] page reads /data/ufo/case/reports/<slug>.md and renders
with MarkdownBody, frontmatter parsed for stat chips.
