W3.7: Dupin contradiction-scan detective + UI integration
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).

The Disclosure Bureau

Investigative wiki + agentic chat sobre o corpus declassificado do US Department of War em war.gov/ufo (116 PDFs, 3.435 páginas, 34k+ entidades, 28 vídeos UAP).

Live: disclosure.top

O que é

Pipeline de IA que transforma documentos UAP/UFO declassificados em uma wiki investigativa navegável + chat agêntico com retrieval semântico bilíngue (EN + PT-BR) e citações com bbox crop no PDF original.

A premissa metodológica é o padrão Karpathy LLM Wiki: ler tudo, compilar conhecimento em markdown cross-referenciado, navegar via wiki-links — não por busca vetorial. Em cima dessa wiki rodamos uma camada de hybrid retrieval (BM25 + BGE-M3 dense + cross-encoder rerank) para perguntas livres no chat.

A camada investigativa segue protocolo Investigation Bureau (Holmes/Poirot/Dupin/Locard + Schneier/Tetlock/Taleb): chain-of-custody, hypothesis tournament, residual uncertainty.

Arquitetura

PDFs (raw/)
  ↓ pdftoppm 72 DPI + pdftotext
processing/ (png + ocr)
  ↓ Sonnet 4.6 subagents (page-rebuilder, image-analyst, table-stitcher)
raw/<doc>--subagent/ (chunks bilíngues + bbox + anomaly flags)
  ↓ scripts/30 (BGE-M3 embed) + 31 (entity_mentions)
Postgres + pgvector + tsvector
  ↓ hybrid_search RPC + reranker
chat agente (OpenRouter) cita [[doc/p007#c0042]] → frontend renderiza crop bbox

Stack

  • Embedding: BGE-M3 self-hosted (1024-dim, multilíngue, $0)
  • Reranker: BGE-Reranker-v2-M3 self-hosted ($0)
  • Vetor + texto: Postgres 15 + pgvector + tsvector bilíngue (pt_unaccent, en_unaccent)
  • LLM (chat): OpenRouter — DeepSeek v4 free como default
  • Frontend: Next.js 15 + React 19 + Tailwind + assistant-ui (Pattern C streaming)
  • Auth + persistência: Supabase self-hosted (GoTrue, PostgREST, Storage, Imgproxy)
  • Reverse proxy: Traefik + Let's Encrypt
  • Imagens: sharp via /api/crop (bbox on-demand, cached 1ano)

Quick start

# 1. Converter PDFs em PNG + OCR (uma vez)
./scripts/01-convert-pdfs.sh

# 2. Rebuild chunks bilíngues (Sonnet 4.6 via Claude Code subagents)
python3 scripts/28-batch-rebuild-all.py --workers 2

# 3. (após batch) Indexar em Postgres + embeddings
python3 scripts/30-index-chunks-to-db.py --skip-existing

# 4. (opcional) Materializar entity_mentions p/ grafo
python3 scripts/31-populate-entity-mentions.py

# 5. Deploy
cd infra/disclosure-stack && ./scripts/deploy.sh
