Extends the settings with an app veil section. There the user can select an app to be excluded from the screenshare. The app list is queried from the tauri backend and then just searched from the frontend. core is extended to pass the excluded bundle ids to screencapture-kit when a display is being shared. An application start listener has been been added which makes the stream to check if the filter needs to be updated when an app is being started mid stream. An app can be added deleted at any time. Settings are persisted, with Notification Center present but disabled by default. Application discovery skips symlinks to avoid recursive scans.
Updated application launch and termination handling to use the more reliable NSWorkspaceDidLaunchApplicationNotification and NSWorkspaceDidTerminateApplicationNotification events. Adds a visible App Veil on the controller side and transports anonymous full-replacement snapshots over LiveKit. Geometry capture runs once per second on an AppVeilHost-owned thread outside the main event loop. The worker reads the WindowServer z-order, clips protected windows to the shared display, subtracts foreground occluders, normalizes the remaining visible fragments, and sends the completed snapshot back to the main loop. It skips WindowServer processing and logs its idle state when no excluded applications are running.

A failed capture-filter refresh leaves protected applications visible in the stream.
refresh_app_veil_filter logs the error and returns. The active stream keeps the previous SCContentFilter. If a protected application launches and this refresh fails, that application's windows stay in the encoded frames while the user expects them to be excluded.
Add a recovery path. Retry the update, or stop the screen share when the filter cannot be applied.

Cap the number of windows and fragments accepted from a remote peer.
sanitize_app_veil_snapshot validates each rectangle but does not limit windows.len() or visible_fragments.len(). A remote participant can send a snapshot containing a very large number of entries. The stored snapshot reaches AppVeilOverlay::draw in core/src/window/screensharing_window.rs, which performs one clipped fill per fragment on every frame. That lets an untrusted peer stall the renderer.
Note also that the publisher guard at line 2364 does not reject the packet when publisher is None, so a participant can seed this state before any screen share starts.
Add explicit upper bounds and drop the payload when it exceeds them.

Use exact identity matching for screen-share cleanup.
ParticipantDisconnected runs for the separate :audio participant, while the screen-share publisher uses :video. The suffix-insensitive match can close an active screen share when only the audio participant disconnects. Use the same exact comparison in the disconnect, mute, and unsubscribe paths. Add a regression test for an audio-only disconnect.

Make App Veil settings persistence atomic.
AppState::write_file uses fs::write, which can truncate the state file before a failed or partial write. Write and sync a temporary file in the same directory, then atomically rename it over the state file. Add a failure-path test that confirms the previous state remains readable.

Show App Veil transport failures to the user.
The catch block only writes to console.error. The backend saves the selection before it sends SetAppVeilBundleIds. If that send fails, the settings refetch still shows the application as enabled while the active capture filter remains unchanged.
Show a persistent error or alert that states App Veil will not apply until restart.

Block keyboard forwarding when keyboard_input_blocked is true.
When self.state.app_veil_snapshot.keyboard_input_blocked is true, handle_window_event still emits ScreenShareInputEvent::KeyInput. Gate this path, clear queued modifier events when blocking starts, and add a regression test.

Show the warning when window restoration fails.
If any Tauri window API call rejects, the listener exits before toast.error runs. Catch window restoration errors separately, then always show the App Veil warning.

Cancel shortcut recording when the Shortcuts section unmounts.
If a ShortcutRow is recording when the section changes, its capture-phase keydown listener remains active. A later modified key press can call the stale onCommit callback and overwrite a shortcut. Add an unmount cleanup that removes listenerRef.current.
