Heal dead push subscriptions from a VAPID key rotation — the reason notifications went silent. registerPush reused whatever getSubscription() returned and only ever subscribed fresh when there was none; a subscription made against an OLD VAPID key can never receive a push (the notifier's send fails with a permanent 403, which was never pruned, and the client kept re-registering the same dead endpoint). Now the client fetches the current VAPID key first and, when an existing subscription's applicationServerKey doesn't match, unsubscribes and re-subscribes against the current key — so a device self-heals on next open. And the notifier prunes 403 endpoints alongside 404/410. Deployed nwcpush on cs
