# Track D Status

**NotificationService LIVE** (2026-09-24): the real dispatcher (`App\Services\Engagement\NotificationDispatcher`,
bound to the frozen `NotificationService` interface) is on this branch
`track-d/T-D-01-notification-platform`. A/B/C: re-run your suites against the
real thing — inject `App\Services\Engagement\NotificationService` (it now
resolves to the real dispatcher, no fakes needed); event-side wiring is
auto-discovered (`NotificationRequested` → `HandleNotificationRequested`).
Criticals bypass mute/quiet/digest at the dispatcher level.

Pre-flight (2026-09-24): Track A Phase 0 verified on `origin/main` — T-A-01…T-A-06
+ T-A-24 all merged (merge commits c7a70f9, 91c1c62, f62aa76, 4f73694, 0d54b58,
4ad28ae, 5f33d23). track_a.md's "T-A-05 pending" line is stale — it is merged
(4ad28ae). GATE 1 pre-condition satisfied for Track D.
