+## Broadcast Extension (share your iPhone SCREEN in a call) — one-time Apple portal setup
+
+Screen sharing from iOS uses a **Broadcast Upload Extension** (`com.bizgaze.connect.broadcast`) — the same
+pattern as the Share Extension. The Codemagic build injects the target, links LiveKit into it, and fetches a
+profile automatically, but the **App Group capability can only be toggled by hand** in the Apple portal:
+
+1. Reuse the SAME App Group as the Share Extension: **`group.com.bizgaze.connect`** (no new group needed).
+2. **Enable the App Groups capability on the broadcast App ID** and assign it to that group:
+ - `com.bizgaze.connect.broadcast` (create this App ID if the first build hasn't yet — `fetch-signing-files
+ --create` registers it, then edit it to add App Groups). The app (`com.bizgaze.connect`) already has the
+ group from the Share Extension setup above.
+ After enabling it, re-run the Codemagic build so `fetch-signing-files` regenerates the profile.
+
+Until the App Group is on the broadcast App ID, the **archive fails code-signing** (entitlement mismatch) —
+that's the expected first-build failure. The shared App Group is how the extension (ReplayKit capture) hands
+screen frames to the app over LiveKit's IPC socket. Receiving OTHERS' shared screens needs none of this — it
+already works. `ios-patch.sh` sets `RTCScreenSharingExtension` + `RTCAppGroupIdentifier` in the app Info.plist
+so LiveKit finds the extension + group.

+// Principal class of the Broadcast Upload Extension (ReplayKit) that lets the iOS user share their screen.

+// HOW IT WORKS: when the user starts a system broadcast, iOS launches THIS extension. LiveKit's LKSampleHandler
+// does everything — on broadcastStarted it opens an IPC socket in the shared App Group (group.com.bizgaze.connect)
+// and streams the ReplayKit sample buffers to the MAIN app, whose LiveKit connection publishes them as a
+// screen-share track. The extension itself never creates a Room / initialises WebRTC, so it stays well under the
+// 50 MB extension memory limit. So this subclass can be empty.
+//
+// The extension finds the app group + reports state to the app via LiveKit's Darwin-notification/socket
+// convention, keyed off this extension's bundle id (com.bizgaze.connect.broadcast) and the default app group
+// group.. Both are also set explicitly on the app side (RTCScreenSharingExtension /
+// RTCAppGroupIdentifier in Info.plist) so there's no ambiguity.
