Supersedes dependabot #264 — this one involves code changes that PR
couldn't make.
## Breaking changes in our usage surface
### v12: default export removed → named `PgBoss` export
Affects every file that imports the SDK:
- `packages/jobs/src/boss.ts`: `import PgBoss` → `import { PgBoss }`
- `packages/jobs/src/worker.ts`: same for the type import
- `packages/jobs/src/types.ts`: `PgBoss.Job<T>` → `Job<T>` (types.ts
re-exports `Job` at the package root in v12)
### v11: queue names restricted to `[A-Za-z0-9_.-]`
Colon `:` is no longer allowed. Renamed the two journal queues that
had it:
- `demo-bot:generate` → `demo-bot-generate`
- `demo-bot:prune` → `demo-bot-prune`
The planner's `expire-sessions` was already valid.
### v12: minimum Node 22.12
Not a code change for us — journal + planner Dockerfiles are on
`node:25-slim`, CI runners on 24.
## Regression guard
Added `assertValidJobName()` in `@trails-cool/jobs`, called by
`startWorker()` before any side effects. Pg-boss v11+ silently accepts
an invalid name then rejects the underlying SQL call later — we fail
loudly at boot instead. Unit tests cover the character-class rule
and exercise the exact old-name (`demo-bot:generate`) as a
regression fence.
## Prod rollout note
Pg-boss v11 dropped the auto-migration path from v10. On deploy, the
live `pgboss` schema from v10 won't migrate cleanly. Simplest path:
`DROP SCHEMA pgboss CASCADE` before the first v12 worker starts —
our jobs are all cron-scheduled and will re-register themselves on
boot, so there's nothing durable to preserve in the queue.
## Verified
- `pnpm typecheck` / `pnpm lint` / `pnpm test` — all clean
- `pnpm exec playwright test --workers=2` — 50/50 passed

`*/90 * * * *` is invalid cron (minute field is 0–59) and degrades
to hourly, producing half the intended bot cadence. Switch to
`0,30 * * * *` (every 30 min) and lower the Bernoulli gate from
0.12 to 0.09 so we still hit ~2–3 walks/day during the 07–21
Berlin window.

Adds a background demo user (`bruno`) plus two pg-boss jobs that generate
public trekking routes and activities in inner Berlin and prune them
after 14 days. Disabled by default everywhere; flip `DEMO_BOT_ENABLED`
only in prod.
- Schema: `synthetic` boolean on routes + activities
- `ensureDemoUser()` idempotent insert + badge on /users/bruno
- Generation gate: 07-21 Berlin local, p=0.12, 40-route cap in 14d
- Initial 4-walk backfill on first enable; retention via daily prune
- Prometheus gauges `demo_bot_synthetic_routes_total` / `_activities_total`
- Unit + DB-gated integration + E2E tests
