W0+W1+W1.2: security hardening, observability, autocomplete, glitchtip, forgejo CI
...
CI / Web — typecheck + lint + build (push) Failing after 1m30s
CI / Scripts — Python smoke (push) Failing after 32s
CI / Web — npm audit (push) Failing after 37s
W0 — security hardening (5 fixes verified live on disclosure.top)
- middleware: gate /api/admin/* same as /admin/* (F1)
- imgproxy: tighten LOCAL_FILESYSTEM_ROOT from / to /var/lib/storage (F2)
- studio: real basic-auth label (bcrypt hash, middleware reference) (F3)
- relations: ENABLE ROW LEVEL SECURITY + public SELECT policy (F4)
- migration 0003: fold is_searchable + hybrid_search update into canonical (TD#2)
W1 — observability + resilience + autocomplete
- studio: HOSTNAME=0.0.0.0 so Next.js binds on loopback for healthcheck
- compose: PG_POOL_MAX=20, CLAUDE_CODE_OAUTH_TOKEN gated by separate env
- claude-code.ts: subprocess timeout configurable (CLAUDE_CODE_TIMEOUT_MS)
- openrouter.ts: retry with exponential backoff + Retry-After + in-memory
circuit breaker (promotes FALLBACK after CB_THRESHOLD failures)
- lib/logger.ts: pino logger (NDJSON prod / pretty dev) + withRequest helper
- middleware: mints correlation_id, stamps x-correlation-id response header,
emits structured http_request log per /api/* call
- messages/route.ts: switch to structured logger
- 60_meili_index.py: push documents + chunks into Meilisearch
- /api/search/autocomplete: parallel meili search (docs + chunks), 5-8ms p50
- search-autocomplete.tsx: debounced dropdown wired into search-panel
W1.2 — Glitchtip + Forgejo self-hosted
- compose: glitchtip-redis + glitchtip-web + glitchtip-worker (v4.2)
- compose: forgejo + forgejo-runner (server v9, runner v6) with group_add=988
- @sentry/nextjs SDK wired (instrumentation.ts + sentry.{client,server}.config.ts)
- /api/admin/throw smoke endpoint (gated by W0-F1 middleware)
- Synthetic event ingestion verified at glitchtip.disclosure.top
- forgejo.disclosure.top up, repo discadmin/disclosure-bureau created,
runner registered (labels: ubuntu-latest, docker)
- .forgejo/workflows/ci.yml: typecheck + lint + build + npm audit + python
syntax + compose validation

search: gate dense recall by cosine-distance threshold in the RPC
...
Root-cause fix for "search returns garbage for absent terms". The hybrid RPC's
dense branch always returned its k nearest vectors regardless of distance, so a
query for a term not in the corpus (e.g. "varginha") surfaced unrelated chunks.
The cross-encoder reranker would filter these but costs 18-62s on CPU —
unusable for interactive search.
Add max_dense_dist (default 0.40) to hybrid_search_chunks: dense neighbours
beyond that cosine distance are dropped server-side. Calibrated from measured
distances — strong semantic match ~0.12-0.20, no real match ~0.46-0.53. BM25
full-text still matches literal terms; the reranker becomes opt-in refinement.
Verified live: varginha/abducao → 0, disco voador/roswell → relevant, all <1s.
