## [Unreleased]

### W2 — UX latency + retrieval eval + vision tool
*2026-05-23 · systems-atelier engagement trace `794f00ba`*

- **TD#8 · Reranker opt-in** (`hybrid.ts`). New `rerank_strategy` field
  on `HybridSearchOptions`: `"always" | "when_top_k_gt" | "never"`, with
  a configurable `rerank_threshold` (default 15). Default strategy is
  `when_top_k_gt` so the slow cross-encoder only runs when the model
  asks for a wider list; top-K ≤ 15 trusts the RPC's RRF order. The
  chat tool calls hybrid_search with threshold 10 so a 10-hit response
  costs ~7s of embed+RPC instead of 12-15s with rerank. `/api/search/hybrid`
  exposes the strategy via `?rerank=always|never|when_top_k_gt` plus
  `?rerank_threshold=N`. Back-compat `?rerank=0` still means "never".
- **O11 · `analyze_image_region` chat tool** (`vision.ts`, `tools.ts`).
  New OpenAI-style function tool that crops a normalized bbox of a page
  PNG with sharp, writes it to a temp file, and asks Claude Code OAuth
  (Sonnet) to Read the local file and answer a question about it.
  Schema: `{doc_id, page, bbox{x,y,w,h}, question, context?}`. Emits a
  `crop_image` artifact for the UI alongside the textual answer. Cost
  budget: ~$0.005–0.02 per call, paid against the user's Max 20x
  quota. Timeout configurable via `VISION_TIMEOUT_MS` (default 120s).
- **TD#12 · `react-force-graph-2d` removed**. The `/graph` page now uses
  `<SigmaGraph>` (already wired for the entity sidebar). One graph
  library is enough. `web/components/force-graph-canvas.tsx` deleted;
  `npm uninstall` removed 37 transitive deps.
- **TD#27 · Context truncation per type configurable**
  (`messages/route.ts`). The four `gatherContext` slice limits are now
  driven by env (`CTX_DOC_FRONTMATTER`, `CTX_DOC_BODY`,
  `CTX_PAGE_FRONTMATTER`, `CTX_PAGE_BODY`) with sensible production
  defaults (was hard-coded 1200/1500/1500/1500).
- **TD#22 · Golden RAG eval** (`tests/rag/`). New harness:
  `golden.yaml` carries 15 curated queries (some calibrated to the
  current top-1 hit on prod, some negative-set sentinels like
  `MJ-12` / `tic-tac` that should NOT return matches), `run.py`
  measures `Recall@k` + `MRR` + `negative_pass_rate` against any
  deployment URL, `baseline.json` is the gate threshold, `last_run.json`
  is the working report. Default behaviour: fail the run when Recall@5
  drops > 0.05 from baseline. CI workflow runs against
  `https://disclosure.top` on every push.
  - First baseline (rerank=never): **Recall@5 = 0.2083, MRR = 0.25,
    Negative pass = 1.0**. Golden set still needs curation —
    intentionally conservative now so drift detection is meaningful.
- **ADRs published to `docs/adrs/`** — ADR-001 (embedding + rerank stack),
  ADR-002 (Investigation Bureau runtime — Bun + LISTEN/NOTIFY + 8 security
  gates, to be implemented in W3), ADR-003 (LLM routing policy), ADR-004
  (auth + RLS evolution), ADR-005 (self-hosted by default).

#### Verified on `disclosure.top` (2026-05-23T21:55Z):
- `/api/search/hybrid?q=Roswell&top_k=5` → HTTP 200 in 6.7s (embed-only,
  rerank skipped per default strategy)
- `/api/search/hybrid?q=Roswell&top_k=20&rerank=always` → confirmed slow
  (>30s, hits cross-encoder)
- Typecheck `web/` clean; `react-force-graph-2d` no longer in
  `package.json`
- `tests/rag/run.py` against prod → 15 queries answered, baseline written
- 5 ADRs committed under `docs/adrs/`

### W1.2 — Glitchtip + Forgejo self-hosted
*2026-05-23 · systems-atelier engagement trace `794f00ba`*

- **Glitchtip self-host** (Sentry-compatible error monitor). New services
  in compose: `glitchtip-redis`, `glitchtip-web`, `glitchtip-worker`
  (v4.2, uWSGI on 8080). Database `glitchtip` carved out of
  `disclosure-db` as a separate role/DB. Bootstrap done via Django
  `manage.py shell` — admin user, organization `the-disclosure-bureau`,
  project `web`, DSN issued. SDK wired: `@sentry/nextjs` + `instrumentation.ts`
  + `sentry.{client,server}.config.ts`. `/api/admin/throw` smoke endpoint
  is admin-gated. Live at `https://glitchtip.disclosure.top` (TLS issued
  by Let's Encrypt via Traefik). Synthetic event verified — POST
  `/api/1/store/` → 200 + event id.
- **Forgejo self-host + Actions CI**. New services in compose: `forgejo`
  (v9, default branch `main`) and `forgejo-runner` (v6, registered to
  the host docker socket via `group_add: [988]`). Admin user
  `discadmin` created via `forgejo admin user create` (the literal
  `admin` is reserved). Runner bootstrap on first start: registers if
  `.runner` absent, then `forgejo-runner daemon`. Repo
  `discadmin/disclosure-bureau` created via API; this commit was the
  first push and triggered `W0+W1+W1.2: …` workflow at task 1.
- **`.forgejo/workflows/ci.yml`** — three jobs: `web` (typecheck +
  lint + production build), `python` (compile scripts + validate
  compose YAML), `audit` (`npm audit --production`). Default container
  per job, all behind the `ubuntu-latest` label served by the
  self-hosted runner.

#### Verified on the stack (2026-05-23T21:19Z):
- `glitchtip.disclosure.top` → HTTP 200, real Let's Encrypt cert,
  Glitchtip CSP headers present.
- POST `/api/1/store/` → 200, event_id `cb17d723…` returned.
- `forgejo.disclosure.top` → HTTP 200, Forgejo welcome page.
- Forgejo runner logs: `runner: disclosure-runner … declared
  successfully`, `[poller 0] launched`, `task 1 repo is
  discadmin/disclosure-bureau` (CI job picked up).
- First Forgejo Actions workflow run: `status=running` on the commit
  pushed by this changelog.

### 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.
