Background Hono/Bun service that scans mana_sync for due Missions and
will plan them via mana-llm without requiring an open browser tab.
Complements the foreground `startMissionTick` in the webapp.
v0.1 scope — scaffold that's deployable, boots cleanly, and reads real
data. Execution write-back is tracked as the next PR so we don't commit
a half-baked proposal-sync design.
Shipped:
- Hono app on :3066 with `/health` + service-key-gated `/internal/tick`
- `src/db/missions-projection.ts` — field-level LWW replay of
`sync_changes` for appId='ai' / table='aiMissions' → live Mission
records. Mirrors the webapp's `applyServerChanges` semantics against
Postgres instead of Dexie.
- `src/db/connection.ts` — bounded `postgres.js` pool (max 4, idle 30s)
- `src/cron/tick.ts` — overlap-guarded scheduler, `runTickOnce()` also
reachable via HTTP for CI/ops triggering
- `src/planner/client.ts` — mana-llm HTTP client shape
(OpenAI-compatible `/v1/chat/completions`)
- `src/middleware/service-auth.ts` — X-Service-Key gate, no end-user JWTs
reach this service
- Dockerfile + graceful SIGTERM shutdown (stops timer + releases pool)
Not yet implemented (documented in CLAUDE.md with design trade-offs):
- Prompt/parser server-side copies — today they live in the webapp.
Recommended next step: extract `@mana/shared-ai` package.
- Input resolvers for notes / kontext / goals — need projections or a
mana-sync internal endpoint
- Plan → Mission-iteration write-back + how proposals get back to the
user's device (leaning option (a): server writes iterations, the
webapp's sync effect translates them into local Proposals)
