## [Unreleased]

### W1 — Observability + resilience + Meili autocomplete
*2026-05-23 · systems-atelier engagement trace `794f00ba`*

- **Studio container fixed (carry-over from W0)** — root cause was Next.js
  standalone binding to the container hostname only. The docker healthcheck
  (`fetch 127.0.0.1:3000/api/profile`) looped on `ECONNREFUSED`, the service
  never went healthy, and Traefik returned 404 because the upstream wasn't
  responding. Fix: `HOSTNAME: 0.0.0.0` in the studio env. Studio now
  `healthy`, basic auth from W0-F3 enforces correctly (no-auth → 401,
  valid creds → 307), and Let's Encrypt issued a real cert for
  `studio.disclosure.top` once the route started responding.
- **TD#10 · PG pool max** — `PG_POOL_MAX=20` (was hard-coded 5) configurable
  via .env; default raised for prod. Files: `docker-compose.yml`, `.env`.
- **W1-F8 · `CLAUDE_CODE_OAUTH_TOKEN` gated** — only injected into the `web`
  service when explicitly set in `CLAUDE_CODE_OAUTH_TOKEN_FOR_WEB`. Default
  empty since `CHAT_PROVIDER=openrouter` does not need it. Reduces blast
  radius if web container is compromised. Files: `docker-compose.yml`, `.env`.
- **TD#30 · Subprocess timeout configurable** — `CLAUDE_CODE_TIMEOUT_MS`
  env now controls the `claude -p` subprocess timeout (default 90s,
  matches prior hard-coded value). Files: `web/lib/chat/claude-code.ts`.
- **TD#23 · OpenRouter retry + circuit breaker** — `fetchOpenRouter()`
  wraps every call with: retry up to `OPENROUTER_RETRY_MAX` (default 2)
  on 408 / 425 / 429 / 500 / 502 / 503 / 504 and network errors, with
  exponential backoff and `Retry-After` honored; in-memory circuit
  breaker trips when `PRIMARY` fails `CB_THRESHOLD` times (default 3)
  within `CB_WINDOW_MS` (60s), promoting `FALLBACK` for `CB_COOLDOWN_MS`
  (2 min). Both `sendOnce` and `openrouterStreamCall` go through it.
  Files: `web/lib/chat/openrouter.ts`.
- **TD#6 · Structured logging with pino** — `web/lib/logger.ts` provides
  a JSON logger (NDJSON in prod, pretty in dev) plus `withRequest()`
  helper for correlation-id-bound child loggers. Edge runtime falls back
  to a console adapter. Middleware now mints a `correlation_id` for
  every request, stamps the response header (`x-correlation-id`), and
  emits one structured `http_request` line per `/api/*` call with
  method, path, status, and duration. `messages/route.ts` switched to
  the new logger. Files: `web/lib/logger.ts`, `web/middleware.ts`,
  `web/app/api/sessions/[id]/messages/route.ts`, `web/package.json`.
- **Meilisearch indexer + `/api/search/autocomplete` + UI** — the previously
  idle Meili instance now backs typo-tolerant prefix search. Indexer
  script `scripts/maintain/60_meili_index.py` ingests documents
  (canonical_title + collection) and is-searchable chunks (content_pt +
  content_en + meta). The new `/api/search/autocomplete?q=...` route
  hits both indexes in parallel with a 2s abort and returns a merged
  payload. `SearchAutocomplete` React component drops a debounced
  dropdown under the `/search` input. Median latency in production:
  **5–8ms**. Files: `scripts/maintain/60_meili_index.py`,
  `web/app/api/search/autocomplete/route.ts`,
  `web/components/search-autocomplete.tsx`,
  `web/components/search-panel.tsx`.

#### Verified on `disclosure.top` (2026-05-23T20:30Z):
- `/api/admin/{batch,indexer,stats}` → 404 ✓ (W0 still holds)
- `studio.disclosure.top` no-auth → 401 · `admin:<DASHBOARD_PASSWORD>` → 307 ✓
- Let's Encrypt cert issued for `studio.disclosure.top` ✓
- Autocomplete `q=Roswell` → 8 chunks in 8ms; `q=Sandia` → 1 doc + 8 chunks
  in 8ms; `q=1947` → 5 docs + 8 chunks in 6ms ✓
- `x-correlation-id` header present on `/api/search/hybrid` response
  (e.g. `c48b7cc761dac172`) ✓
- 18 513 searchable chunks indexed into Meili ✓
- OpenRouter retry/breaker present (7 references in source) ✓

#### Deferred to W1.2 / W2 (need user-in-loop steps):
- **Glitchtip self-host** — needs DNS for `glitchtip.disclosure.top`,
  initial signup-as-superuser, project DSN copied to .env. Logger and
  middleware are already feeding the data; SDK wiring is one PR.
- **Forgejo Actions self-host CI** — Forgejo server + runner bootstrap,
  initial admin account, repo migration / mirror. Recommend a separate
  session because of the depth of setup.

### W0 — Hardening (security + reproducibility)
*2026-05-23 · systems-atelier engagement trace `794f00ba-7cb6-4b90-a48e-23ebd02d1f44`*

- **F1 · Auth gate em `/api/admin/*`** — middleware now matches `/api/admin`
  too; non-admin (including anonymous) gets HTTP 404. Verified: `curl`
  on `/api/admin/{batch,indexer,stats}` returns 404 publicly. Files:
  `web/middleware.ts`.
- **F2 · Imgproxy filesystem root tightened** — `IMGPROXY_LOCAL_FILESYSTEM_ROOT`
  moved from `/` (entire VPS root) to `/var/lib/storage` (Storage backend
  mount only). Reduces blast radius of any future imgproxy CVE. Files:
  `infra/disclosure-stack/docker-compose.yml`.
- **F3 · Studio basic auth label** — replaced the dead-end
  `basicauth.usersfile=/dev/null` with a real bcrypt-hashed credential
  (`DASHBOARD_USERNAME` / `DASHBOARD_PASSWORD` from `.env`) and wired the
  middleware into the router via `disclosure-studio.middlewares=
  disclosure-studio-auth@docker`. *Caveat:* the Studio container itself
  has a pre-existing instability (restarts in a Next.js loop, status
  `unhealthy`) so the front-end currently returns 404 from Traefik. When
  Studio is stabilized (queue for W1), the basic auth will kick in. Files:
  `infra/disclosure-stack/docker-compose.yml`.
- **F4 · RLS on `public.relations`** — `ENABLE ROW LEVEL SECURITY` + public
  `SELECT` policy + `GRANT SELECT TO anon, authenticated`. Aligns with
  every other public table. Files: `infra/supabase/migrations/0003_w0_hardening.sql`.
- **TD#2 · `is_searchable` folded into canonical migrations** — the column,
  reclassification rules, partial index, and the updated `hybrid_search_chunks`
  RPC (BM25 + dense, both filtered by `is_searchable`) are now in migration
  `0003_w0_hardening.sql`. A clean bootstrap on a fresh VPS produces a
  searchable database without any `scripts/maintain/47-48` post-hoc patches.
  Files: `infra/supabase/migrations/0003_w0_hardening.sql`.

#### Verified on `disclosure.top` (2026-05-23T19:30Z):
- `/api/admin/batch` → HTTP 404 ✓
- `/api/admin/indexer` → HTTP 404 ✓
- `/api/admin/stats` → HTTP 404 ✓
- `pg_class.relrowsecurity` = `t` for chunks, documents, entities,
  entity_mentions, **relations** ✓
- `is_searchable` distribution: 18 513 searchable / 10 046 not-searchable
  (35% of corpus deduplicated from results) ✓
- `/api/search/hybrid?q=Roswell` → HTTP 200, 10 hits, first `c0527` ✓
- Studio: Traefik labels in place; container itself unhealthy (separate
  issue, deferred to W1) ⚠

#### Notes for clean-install reproducibility:
- `0003_w0_hardening.sql` MUST be applied as `supabase_admin`, not
  `postgres`, because public.chunks / .entities / .relations are owned by
  `supabase_admin`. The migration file documents this in its header.
