 - HTTP queryFn remains as fallback for initial load before WS connects
 - `staleTime: Infinity` on all WS-subscribed queries -- relies on WS for freshness
 - `useQuerySubscription` does NOT re-subscribe if WS connects after hook mounts -- latent bug
-- Workspace cache updated by: onMutate (optimistic), WS q:snapshot/q:delta, useWorkspaceInitEvents (Tauri event for init progress)
-- Session events (session:message, session:error, session:status-changed) as Tauri events are now DEAD -- Rust socket.rs still emits them but no frontend listener exists
-- useGlobalSessionNotifications now observes React Query cache, not Tauri events
+- Workspace cache updated by: onMutate (optimistic), WS q:snapshot/q:delta, useWorkspaceInitEvents (IPC event for init progress)
+- useGlobalSessionNotifications now observes React Query cache, not IPC events
 - query-engine.ts returns camelCase (hasOlder/hasNewer) vs HTTP snake_case (has_older/has_newer) -- field name mismatch bug
-- dispatchInvalidation is a complete no-op (every resource branch is empty)
-- `sendCommand` and `onEvent` in WS client are exported but never consumed
-- `incrementalFetchAndMerge`, `mergeNewerMessages`, `getLastRealSeq` are dead code in messageCache.ts
+- `q:mutate` / `q:mutate_result` protocol wired in backend but frontend uses HTTP mutations exclusively
+- `sendCommand` and `onEvent` in WS client are exported and consumed (PTY commands use sendCommand, tool relay uses onEvent)
+
+## Electron Desktop Layer (Post-Tauri Migration)
+
+- Electron 35 in use; `BrowserView` deprecated since Electron 30 -- migration to `WebContentsView` needed
+- Preload uses ESM (.mjs output) requiring `sandbox: false` -- this is expected
+- Preload allowlist pattern: ALLOWED_INVOKE_CHANNELS + ALLOWED_EVENT_CHANNELS gate all IPC
+- Duplicate ipcMain handlers exist (snake_case + native: prefix) for migration compat -- should be consolidated
+- `browser:network-request` emitted by main process but no consumer or allowlist entry exists
+- `browser:console-message` sent from browser preload but no ipcMain handler buffers it
+- `clear_file_cache` and `invalidate_file_cache` in allowlist but no handler or caller
+- No test coverage for apps/desktop/ (8 files, ~800 lines)
+- Backend process management: exponential backoff restart, port-changed IPC to renderer, WS reconnect chain
+- Sidecar spawned by backend (not Electron main), tracked in server.ts module scope
