Closes a UX gap the user surfaced: W3.5-3.8 built 8 detectives, 4 new
URL endpoints (/jobs/[id], /h/[id], /c/[slug], /api/h/[id]/red-team)
and a chat tool, but the homepage was unchanged — the bureau was
invisible unless you knew the URL or asked the chat to invoke
request_investigation.
Homepage (web/app/page.tsx):
- Title `▍ war.gov/ufo — Investigative Wiki` → `▍ The Disclosure Bureau`
- Subtitle expanded from "Holmes · Poirot · Dupin · Locard" to all 8
detectives (Holmes · Locard · Dupin · Schneier · Poirot · Taleb ·
Tetlock · Case-Writer)
- New `🔎 bureau` topbar link (gold, between graph/stats and batch)
- BureauSnapshot inserted right after the header
BureauSnapshot (web/components/bureau-snapshot.tsx) — server component:
- 8 detective tiles with role labels (each in its tone color)
- 6 clickable counters (evidence / hypotheses / contradictions /
witnesses / outliers / case reports) — anchor to /bureau#section
- 6 "recent artefacts" columns surfacing the last 3-4 of each kind:
hypotheses with prior→posterior + band + ↳reviewed_by marker,
contradictions with topic + resolution_status, evidence with
Grade badge + verbatim quote, outliers with title + scope.kind,
witness analyses with canonical_name + credibility + verdict,
case reports with slug + link to /c/<slug>
- "Recent jobs" strip linking to /jobs/[id] color-coded by status
- Reports read from /data/ufo/case/reports/ via fs.readdir + stat,
sorted by mtime — no DB round-trip needed for that section
/bureau (web/app/bureau/page.tsx) — full hub:
- Header with full counts
- 7 sections (anchored to homepage counter links): Case reports,
Hypotheses, Evidence, Contradictions, Outliers, Witnesses,
Recent jobs table — each rendering up to 100 rows
- Reports section parses frontmatter from each .md to surface topic
+ n_hypotheses + n_evidence on the card
Runtime fixes batched in:
- Poirot: coerce entity_pk via Number() — node-postgres returns
BIGINT as string by default; writer's Number.isFinite() rejected
it as "person_entity_pk required" (j-edgar-hoover retry path)
- Tetlock: write_calibration rationale cap 600 → 1200 chars. Prompt
still asks ≤ 600 but a 2× slack beats failing the job on honest
analysis. Observed live: Tetlock emitted ~620 chars on H-0003 and
the writer rejected the entire calibration.
- Case-Writer: Promise.all of 5 queries × max_parallel=2 jobs
demanded up to 10 connections against the investigator role's
rolconnlimit=4 → "too many connections for role investigator".
Sequentialized — the LLM call is the hot path, not these queries.
Smoke results visible now on the homepage:
- 3 hypotheses (H-0001/2/3) about green fireballs origin
- 3 contradictions (R-0001/2/3) about color, geographic confinement,
exclusive-green vs multicolored
- 2 evidence cards (E-0002/3) Grade B
- 3 outliers (G-0001/2/3) — including Taleb's deliberate
meteor-shower-camouflage flag
- 1 case report at /c/green-fireballs-sandia (Watson 13.4 KB,
five-act narrative, fully cited)

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.
