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.

Adds the fourth AI detective in the Investigation Bureau runtime: Bruce
Schneier, who attacks an existing hypothesis as a red-team operator.
Runtime:
- prompts/schneier.md — discipline (don't disprove, just attack;
structured output with hidden_assumptions, failure_modes,
alternative_explanations, recommended_tests, verdict_one_sentence;
severity ∈ {low, medium, high}; emit INSUFFICIENT_HYPOTHESIS when
the input is too thin)
- src/detectives/schneier.ts — reads the hypothesis row + evidence
chain (joined via evidence_refs FK), feeds Claude with the
arguments + verbatim quotes, parses strict JSON object
- src/tools/write_red_team_review.ts — UPDATEs hypotheses.reviewed_by
+ updated_at; APPENDS (or replaces if re-reviewed) a structured
"## Red-team review (Schneier · X severity)" section to
case/hypotheses/H-NNNN.md. Caps each list at 5 entries × 240 chars,
validates verdict ≤ 280 chars.
- orchestrator: new `red_team_review` kind dispatching to runSchneier
Chat + UI:
- request_investigation gains kind=red_team_review + hypothesis_id arg
(validated against H-NNNN regex); detective auto-resolves to schneier
- chat-bubble inline card paints Schneier in red (#ff3344)
- /jobs/[id] page swaps title/subtitle/tone per detective; the
"Question" label becomes "Hypothesis under attack" for red_team_review
New /h/[hypothesisId] page (hypothesis dossier):
- Server-rendered from public.hypotheses + public.evidence (joined
via evidence_refs FK + chunk lookup)
- Header: ID + creator + reviewer (highlighted when Schneier has
visited), position as headline, question subtitle, Tetlock band
- Prior + posterior bars with Δ-delta indicator
- Argument grid: argument_for (green) vs argument_against (pink)
side-by-side with [[wiki-link]] auto-linking to source chunks
- Evidence chain: each E-NNNN with Grade A/B/C badge, verbatim
blockquote, link to source page
- Red-team review panel: parses the markdown section in the case
file (severity badge, verdict, 4 bullet panels for
hidden_assumptions / failure_modes / alternative_explanations /
recommended_tests). Empty state when not yet reviewed.
RedTeamRequestButton client component + POST /api/h/[id]/red-team —
authenticated user can trigger Schneier in one click; UI swaps to
"acompanhar" link to /jobs/[id] once queued.

Two regressions surfaced in the smoke test that put Dupin from
0/3 contradictions written → 3/3 in the next run.
1. Single-doc scope was too narrow for Dupin's task.
Holmes's question about Sandia returned 4 chunks scoped to one doc,
but Dupin's terser "topic" form yielded only 1. Solution: Pass-1
tries the requested doc_id; if the head is < 2 chunks, Pass-2
widens to the whole corpus. Audit event carries `scope_widened`
so the case-writer can later flag cross-doc contradictions
distinctly. The unscoped retry hit 9 chunks and produced 3
contradictions across 3 different docs.
2. Chunk-block header was ambiguous to the model.
`--- doc-id/p007#c0042 ---` led Claude to parse `chunk_id` as
"p007#c0042" or "p007/c0042" in the JSON output. write_contradiction
then refused the FK lookup with "chunk not found". Fix:
- Explicit `doc_id:` / `chunk_id:` / `page:` lines per chunk
in the rendered block (no slashes/hashes the model can fold).
- Defensive normalizeChunkId() in write_contradiction.ts strips
any pNNN prefix and keeps only the trailing cNNNN — so the
writer is forgiving without losing strictness on the topic +
statement validation.
Smoke now produces (job 6deddf4b):
R-0001 (3 chunks) — Color of the fireball(s) in incident summaries
R-0002 (2 chunks) — Geographic confinement of green-fireball sightings
R-0003 (3 chunks) — Whether the phenomenon was exclusively green or
also red/multicolored
R-0003 connects 3 different declassified documents: the Los Alamos
conference (exclusively-green category), a retrospective document
(red OR green), and Incident 229 (red, blue, yellow — no green).
Real cross-doc contradiction, fully cited.

Adds the third AI detective in the Investigation Bureau runtime: C. Auguste
Dupin, who scans a corpus shortlist for pairs (or small groups) of chunks
that cannot both be true under any ordinary reading.
Runtime:
- prompts/dupin.md — discipline (no contradiction without ≥2 distinct
chunk_ids; reject same-vocabulary near-misses; FEW high-confidence
over MANY weak ones; emit `NO_CONTRADICTIONS` when corpus is silent)
- src/detectives/dupin.ts — hybridSearch with k=18 (more chunks than
Holmes because contradictions emerge from comparing dispersed
claims), strict JSON-array parsing, AT MOST 3 contradictions per call
- src/tools/write_contradiction.ts — validates topic + ≥2 positions
drawn from ≥2 distinct chunks, resolves chunk_pk via DB lookup
(rejects positions citing unknown chunks), INSERTs into
public.contradictions + writes case/contradictions/R-NNNN.md
- orchestrator: new `contradiction_scan` kind dispatching to runDupin;
payload { topic, doc_id?, lang?, context_chunks? }
Chat + UI:
- request_investigation gains kind=contradiction_scan + topic arg;
triggered detective auto-resolves to dupin
- chat-bubble inline card renders dupin in orange (#ff8a4d) to
distinguish from holmes (cyan) and locard (green)
- /jobs/[id] page swaps title + subtitle + tone per detective;
"Question" label becomes "Topic" for contradiction_scan
- /api/jobs/[id] hydrates public.contradictions when outputs[] surfaces
contradiction_ids
- job-status-poller renders ContradictionCard: topic + N positions
(verbatim statements quoted, stance label optional, link to source
chunk) + optional notes panel, with resolution_status badge
(open/resolved/irreconcilable)
R-NNNN shares the contradiction_id_seq slot with relation per
CLAUDE.md naming — same conceptual class (a connection between two
pieces of evidence in tension).

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.

Token consolidation:
- docker-compose web service now reads ${CLAUDE_CODE_OAUTH_TOKEN} directly,
drop the W1-F8 CLAUDE_CODE_OAUTH_TOKEN_FOR_WEB indirection (user feedback:
one var name, no _FOR_WEB suffix).
investigator-runtime claude.ts:
- --system-prompt silently dropped by CLI v2.1.150 for multi-KB prompts;
inline the system content into the user prompt with a separator
(mirrors scripts/reextract/run.py pattern).
- Multi-line prompts via positional -- broke ("Input must be provided …");
pipe via stdin instead.
- --allowedTools "" is rejected; when no tools wanted, omit it and explicitly
--disallowedTools the writer/reader set so the model can't reach for any.
investigator-runtime locard.ts:
- Log the raw response (first 600 chars) to container stderr — saved hours
of debugging when the writer rejected.
- Grade fallback: when Locard omits `grade` but provides custody_steps,
infer the highest grade that fits (≥3 → A, ≥2 → B, ≥1 → C).
investigator-runtime write_evidence.ts:
- Filter related_hypotheses entries with empty/null hypothesis_id silently
(Locard sometimes emits [{}] when it knows no link yet) instead of
failing the whole write.
Migration 0006_investigator_serial_sequences.sql:
- BIGSERIAL on the 7 investigation tables created auto-sequences
(evidence_evidence_pk_seq etc) that 0004 forgot to GRANT to the
investigator role. Without those grants every INSERT failed with
"permission denied for sequence …". Grant USAGE/SELECT/UPDATE on each
auto-seq.
Verified live: Locard wrote E-0002 + E-0003 from real Sandia chunks
(green fireball Feb 1949; cobalt particle analysis). Grade B, confidence
high, custody chain of 3 steps with honest gaps. Cost $0.09 for both,
~70s wall.
