 ### Patch Summary
 
-* Disables the notification whitelist check
-* Allows all applications to post notifications
+On firmware 1.5.6, three separate filter points in `NotificationManagerService` block non-whitelisted apps' notifications; this module neutralizes all three, plus a fourth hardcoded block that specifically drops GMS/Wellbeing notifications:
+
+* `checkDisqualifyingFeatures()` — removed the XOR inversion that silently suppressed notifications
+* `PostNotificationRunnable.postNotification()` — forces the per-app permission check to pass
+* `enqueueNotificationInternal()` — bypasses the hardcoded `ALLOWED_PKGS` whitelist
+* `enqueueNotificationInternal()` GMS/Wellbeing special case — no longer drops notifications from Google apps
 * Applied systemlessly via Magisk
 * Fully reversible by removing the module
+* `service.sh` also whitelists all installed apps from battery optimization at boot, so backgrounded apps aren't killed before they can receive push notifications
