W4: bilingual EN + PT-BR Investigation Bureau (CLAUDE.md §3 contract)
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)

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)
