+# Web Push Backend TODO
+
+The client can subscribe and decrypt version 1 push payloads, but reliable delivery requires backend support.
+
+- Generate and securely store a VAPID key pair. Expose only the public key to the web build as `VITE_WEB_PUSH_PUBLIC_KEY`.
+- Add authenticated MTP requests for registering, replacing, and deleting a browser `PushSubscription` per user and installation.
+- Persist the endpoint, `p256dh`, `auth`, expiration time, stable installation ID, and last-seen time.
+- Remove subscriptions when a push service returns HTTP 404 or 410 and rate-limit registrations per user.
+- Send pushes when an encrypted live message cannot be delivered to an active browser client. Define duplicate suppression for clients that receive both MTP and Web Push.
+- Keep the JSON payload within push-provider limits and use this version 1 shape:
+
+```json
+{
+  "version": 1,
+  "senderId": 123,
+  "sender": "Display name",
+  "avatar": "https://optional.example/avatar",
+  "message": { "content": "base64 encrypted message content" },
+  "secret": {
+    "chatId": "123:456",
+    "secretId": "chat:123:456:main",
+    "version": 1,
+    "encryptedSecret": "base64 wrapped chat secret",
+    "kemCiphertext": "base64 KEM ciphertext",
+    "wrappingScheme": "mtp-chat-secret-kem-chacha20poly1305-hkdf-sha256-v1"
+  }
+}
+```
+
+- Ensure the wrapped secret is intended for the receiving user's MTP keyring. The server must never receive plaintext message content or plaintext chat secrets.
+- Decide how edits, deletions, reactions, calls, read states, and per-chat notification cancellation map to push events.
+- Add subscription rotation handling and unregister subscriptions when a user logs out or clears application data.
+- Configure production HTTPS, SPA route fallback, `application/manifest+json` for `manifest.json`, and `Cache-Control: no-cache` for the service worker.
