When a task is created or reassigned to a staff member, a push notification is sent to any devices they have subscribed on. Keys are auto-generated on first boot and stored in the config table (no manual VAPID setup needed). - Backend: web-push dep, push_subscriptions table, lib/push.js (VAPID + send), routes/push.js (vapid-key / subscribe / unsubscribe endpoints), push notify wired into task-core createTask and tasks PATCH reassignment - Frontend: switched vite-plugin-pwa to injectManifest strategy, custom sw.js handles precache + push event + notificationclick, usePushSubscription hook requests permission and registers subscription on login Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
