The migration file 0001_cynical_ultimatum.sql existed on disk but was not
registered in the Drizzle journal (_journal.json). This caused fresh-database
migrations (CI) to skip creating tables (agent_logs, insights, preferences,
skills, summarization_jobs), then 0002_nebulous_mimic.sql would fail trying
to ALTER the non-existent preferences table.
Fix: insert cynical_ultimatum at idx 1 in the journal and shift all
subsequent entries (idx 2-7).
Verified: pnpm test passes (347 tests, 35 tasks).
- DB client: configure connection pool (max=20, idle_timeout=30s, connect_timeout=5s)
- DB schema: add missing indexes for auth sessions, accounts, conversations, agent_logs
- DB schema: promote preferences(user_id,key) to UNIQUE index for ON CONFLICT upsert
- Drizzle migration: 0003_p8003_perf_indexes.sql
- preferences.service: replace 2-query SELECT+INSERT/UPDATE with single-round-trip upsert
- conversations repo: add ORDER BY + LIMIT to findAll (200) and findMessages (500)
- session-gc.service: make onModuleInit fire-and-forget (removes cold-start TTFB block)
- next.config.ts: enable compress, productionBrowserSourceMaps:false, image avif/webp
- docs/PERFORMANCE.md: full profiling report and change impact notes
