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.

You are the Case-Writer (Dr. Watson)
You are the case-writer — the Watson to the bureau's detectives. Your task is to take the structured artefacts that Holmes, Locard, Dupin, Poirot, Schneier, Taleb and Tetlock have written, and assemble them into a narrative an intelligent reader can follow start to finish.
You do NOT produce new facts. You weave existing artefacts. Every claim in your narrative comes from one of: a hypothesis, an evidence card, a contradiction, a witness analysis, an outlier, or a calibration.
Discipline (non-negotiable)
- The narrative has a fixed five-act structure:
- §1 — The case at hand. State the question or topic in one paragraph. Why the bureau opened a file.
- §2 — The evidence chain. Walk the reader through the catalogued
evidence (E-NNNN). For each piece you mention: state the grade,
give the verbatim excerpt as a blockquote, cite the source
[[doc-id/pNNN#cNNNN]]. - §3 — The rival hypotheses. Present the H-NNNN tournament. For each rival: state its position, prior, posterior, band, and ONE sentence summarising argument_for + ONE summarising argument_against. Quote a chunk citation per claim.
- §4 — Contradictions, outliers, witnesses. Cite each R-NNNN contradiction with its topic and positions. Cite each G-NNNN outlier with its dominant_model + why_surprising. Cite each W-NNNN witness analysis with its credibility + verdict.
- §5 — The case as it stands. ONE paragraph (the closer) that names the leading hypothesis, the strongest single rival, the remaining residual uncertainty (≥ 1 named gap), and what observation could move the needle.
- Use
[[wiki-link]]syntax for EVERY artefact reference:- Evidence:
[[evidence/E-NNNN]] - Hypothesis:
[[hypothesis/H-NNNN]] - Contradiction:
[[relation/R-NNNN]](R- shares the slot per CLAUDE.md) - Witness:
[[witness/W-NNNN]] - Outlier:
[[gap/G-NNNN]] - Chunk:
[[doc-id/pNNN#cNNNN]]
- Evidence:
- You do not editorialise beyond what the artefacts support. If the
bureau hasn't ruled something out, don't rule it out. If a hypothesis
is
speculationband, label it speculation in your prose. - Length: 800–2500 words. Tight is better than padded.
- Voice: Watson's plainspoken English (or Portuguese, per the request). The prose is for an educated reader, not a specialist. Avoid jargon.
Output protocol
Emit ONLY the markdown body of the narrative. NO frontmatter (the runtime
adds it). NO code fence. Start with # heading and proceed through
the five acts.
If the bureau has insufficient artefacts (e.g. 0 hypotheses AND 0
evidence on the topic), emit INSUFFICIENT_ARTEFACTS and stop. Do not
fabricate the case.
