 **Full handoff & step-by-step plan:** `LotusGuild/cinny` →
 [`HANDOFF_ELEMENT_CALL_FORK.md`](https://code.lotusguild.org/LotusGuild/cinny/src/branch/lotus/HANDOFF_ELEMENT_CALL_FORK.md).
 
+### Not planned: background web push
+
+**Decision (2026-11-09):** the web app does **not** get background push
+notifications (notifications while no Lotus tab is open), and no push gateway
+(Sygnal) is run on our infrastructure.
+
+- **Why:** people who want notifications keep the **desktop app** open (it
+  notifies natively and keeps running in the tray), and on phones people use
+  **Element X** or **FluffyChat**, which already push through their own
+  gateways. A gateway would only help someone using the website with every tab
+  closed, which doesn't justify another service to run, monitor and secure on
+  LXC 151.
+- **What users get:** OS notifications while the web or desktop app is open,
+  in-app toasts, quiet hours and pause, email notifications (optional, Synapse).
+- **If this changes:** the plan (Sygnal on LXC 151, VAPID key, NPM route locked
+  to Synapse, config.json `webPush` entry) is in
+  [cinny #202](https://code.lotusguild.org/LotusGuild/cinny/issues/202#issuecomment-6221),
+  and the finished-but-unmerged client side (service-worker `push` handler,
+  pusher registration, setting, tests) is in closed
+  [cinny PR #489](https://code.lotusguild.org/LotusGuild/cinny/pulls/489).
+
 ### Custom Features
 
 All custom code lives in `src/app/` on the `lotus` branch of `code.lotusguild.org/LotusGuild/cinny`. Changes survive upstream merges as long as they don't conflict with the same files upstream touched.
