Phase 17 Plan 02: Scheduler + Storage Summary

gocron v2.19.1 wrapper with SQLite persistence for subscribers and scheduled scan jobs, callback-based scan/notify extensibility

Performance

• Duration: 2 min
• Started: 2026-04-06T14:25:04Z
• Completed: 2026-04-06T14:27:08Z
• Tasks: 2
• Files modified: 8

Accomplishments

• Created pkg/scheduler/ package wrapping gocron with Start/Stop lifecycle and DB-backed job persistence
• Implemented full CRUD for subscribers (Add/Remove/List/IsSubscribed) and scheduled_jobs (Save/List/Get/Delete/UpdateLastRun/SetEnabled)
• Added subscribers and scheduled_jobs tables to schema.sql
• All 5 tests pass: storage round-trip, subscriber round-trip, scheduler start/add/remove/run

Task Commits

Each task was committed atomically:

1. Task 1: Add gocron dependency, create storage tables, and subscriber/job CRUD - c8f7592 (feat)
2. Task 2 RED: Failing tests for scheduler package - 89cc133 (test)
3. Task 2 GREEN: Implement scheduler package - c71faa9 (feat)

Files Created/Modified

• pkg/scheduler/scheduler.go - Scheduler struct wrapping gocron with Start/Stop/AddJob/RemoveJob/RunJob/ListJobs
• pkg/scheduler/jobs.go - Job and JobResult types
• pkg/scheduler/scheduler_test.go - 5 tests covering storage, subscriber, and scheduler lifecycle
• pkg/storage/subscribers.go - Subscriber struct and CRUD methods on DB
• pkg/storage/scheduled_jobs.go - ScheduledJob struct and CRUD methods on DB
• pkg/storage/schema.sql - subscribers and scheduled_jobs CREATE TABLE statements
• go.mod - gocron/v2 v2.19.1 promoted to direct dependency
• go.sum - Updated checksums

Decisions Made

• ScanFunc callback decouples scheduler from engine -- Plan 17-04 wires real scan logic
• OnComplete callback bridges scheduler to notification system without direct bot dependency
• Disabled jobs skipped during Start() but remain in DB for re-enabling via SetJobEnabled

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• pkg/scheduler/ ready for CLI wiring in Plan 17-03 (schedule add/list/remove commands)
• Subscriber storage ready for bot /subscribe handler in Plan 17-01
• OnComplete callback ready for notification bridge in Plan 17-04
