Fix medium-severity spec drift across 17 specs
- authentication-methods: document completeAuth mode param ("redirect"|"json");
  clarify add-passkey nudge (no dismiss mechanism, disappears on passkey add)
- journal-auth: session maxAge is 30 days; terms allow-list uses /legal/ prefix
  matching (broader than fixed list of paths)
- session-notes: mark awareness isolation and UndoManager isolation as not yet
  implemented (shared instances in current code)
- activity-feed: add fan-out scenario for visibility change to public
- explore: note that ?perPage is not yet implemented (hardcoded page size)
- multi-day-routes: add per-day GPX track split scenario (splitByDays option);
  document overnight vs isDayBreak naming gap
- osm-poi-overlays: debounce is 800ms + 2000ms min interval (not 500ms);
  retry is not automatic (fires on next viewport change)
- brouter-integration: rate limit corrected to 300/hour; add segment-cache
  requirement (client caches per-pair segments)
- wahoo-route-push: OAuth state shape uses camelCase (returnTo, pushAfter
  object) not snake_case with push_after boolean
- komoot-import: document noop adapter / ConnectedServiceManager bypass;
  note four Komoot-specific routes that bypass the generic OAuth framework
- background-jobs: exponential backoff not wired (retryLimit only); add SIGINT
- connected-services: add revoked status; name ConnectionNotActiveError
- infrastructure: add INTEGRATION_SECRET and SENTRY_DSN to env var lists;
  split secret decryption scenario by workflow (cd-apps vs cd-infra)
- secret-management: correct CD decryption — cd-apps only decrypts app.env;
  cd-infra decrypts both
- transactional-emails: welcome email is async (pg-boss job); magic-link email
  includes 6-digit numeric code
- journal-route-detail: websites are https: links (not mailto:); opening_hours
  is also displayed
- local-dev-environment: add mobile app (Expo) dev commands

Purpose

Shared background job infrastructure for trails.cool apps, built on pg-boss. Provides a single PostgreSQL-backed queue used by both the planner and journal for one-shot, retried, and cron-scheduled work (e.g., session expiry, periodic maintenance), with worker lifecycle tied to the server process and observability via the existing Grafana stack.

Requirements

Requirement: Job queue initialization

The @trails-cool/jobs package SHALL initialize a pg-boss instance using the app's DATABASE_URL and export a function to start the worker.

Scenario: Worker starts with server

  • WHEN the planner or journal server starts
  • THEN pg-boss connects to PostgreSQL, creates/migrates the pgboss schema if needed, and begins polling for jobs

Scenario: Worker stops on shutdown

  • WHEN the server process receives SIGTERM or SIGINT
  • THEN pg-boss completes any in-progress jobs and stops gracefully before the process exits

Requirement: Cron job scheduling

The system SHALL support registering recurring jobs with cron expressions.

Scenario: Register a cron job

  • WHEN a job is registered with a cron expression (e.g., 0 * * * * for hourly)
  • THEN pg-boss creates a schedule that enqueues the job at the specified interval

Scenario: Cron job survives restart

  • WHEN the server process restarts
  • THEN existing cron schedules persist and continue firing without re-registration conflicts

Requirement: Job retry policy

Jobs SHALL support configurable retry limits. The JobDefinition type exposes retryLimit and expireInSeconds; exponential backoff (retryDelay/retryBackoff in pg-boss terms) is not currently wired.

Scenario: Transient failure retry

  • WHEN a job handler throws an error
  • THEN pg-boss retries the job up to the configured retryLimit

Scenario: Permanent failure

  • WHEN a job exhausts all retries
  • THEN the job moves to the failed state and remains queryable for debugging

Requirement: Job handler timeout

Each job handler SHALL have a configurable execution timeout.

Scenario: Job exceeds timeout

  • WHEN a job handler does not complete within its timeout
  • THEN pg-boss marks the job as failed with a timeout error
