Primary responsibility

Opens the in-app notification center showing the user’s history of received notifications. Source-of-truth is wp_mam_notification_history (renamed from wp_tsl_local_app_notifications_history in PR #31, with backward-compat aliases). Read through MAM_Notification_History_Repository.

JSON shape

{
  "notifications": [
    { "id": "1", "title": "...", "body": "...", "read": false, "ts": "..." },
    ...
  ],
  "unread_count": 3
}

The badge count comes from unread_count.

Hooks involved

Gotchas

• In-app history is separate from push delivery. A push notification that was sent may not show in the in-app history if the notification type was configured for push-only with 'in_app' disabled.
• clean_notifications() runs in phase_finalize and trims the payload to active items — old / deleted notifications are excluded automatically.
• Mark-read-on-open is a write (it updates wp_mam_notification_history); high-frequency open events have measurable DB load.
