// NotificationMigrations creates the one table Phase 9d needs:
|
|
//
|
|
// notification_log — one row per (event, lead_days, audience, channel)
|
|
// that the cron scanner has already attempted. The UNIQUE constraint
|
|
// makes the cron idempotent — running it twice on the same day does
|
|
// not re-send.
|
|
//
|
|
// channel ∈ {'matrix', 'email'} — set by the dispatcher.
|
|
// audience ∈ {'parents', 'students'}.
|
|
// status ∈ {'sent', 'failed', 'skipped'} — 'skipped' when the upstream
|
|
// service URL isn't configured, so we know not to count it as failure.
