Scene strip now renders in canonical F-key order regardless of persisted SortOrder. The strip loads Scenes ORDER BY SortOrder while each tab's F-key label is name-derived, so a session that persisted Chat before BRB (found on the creator's DB: SortOrder 2/3) showed tabs 'Chat F4' then 'BRB F3'. MainViewModel.LoadLayout now calls the new ReorderScenesToCanonical() - the five canonical scenes reorder to Starting, Live, BRB, Chat, Ending (F1-F5, stable among renamed non-canonical scenes), and the next auto-save re-stamps SortOrder so the heal persists. One integration test (SceneOrderTests) seeds the swapped-order DB and asserts loaded order, F1-F5 labels, and that a save persists the corrected ordering. 423 pass, 0 build warnings. (Unit: scene order)

 ## Branch
 - main (no feature branch). Pushed through `5685c5d` (TRAX toggle); everything after is local,
   **not pushed** (push at the creator's call).
 
 ## New work unit (this handoff) — READY TO VERIFY, do not commit yet
-- **Fix** for the "desktop is locked once the app starts" report — `MainWindow.xaml.cs` +
-  `ViewModels/MainViewModel.Background.cs` (`ShowActivated = !FullscreenGameRunningNow`, see
-  `bugs.md` entry 2026-10-10). Scope-locked files: `MainWindow.xaml.cs`,
-  `ViewModels/MainViewModel.Background.cs`, `ViewModels/MainViewModel.cs` (detector seam line),
-  `ytLive.Tests/DesktopLockTests.cs` (new), `bugs.md`, this file.
-- **Regression tests:** `DesktopLockTests` (3 tests) drive the rule through the NEW
-  `FullScreenDetectorOverride` test seam (the same seam pattern as `WindowEnumeratorOverride`) —
-  no real Win32 foreground state is touched: full-screen game at launch ⇒ `ShowActivated=false`;
-  normal launch ⇒ still `true`; `FullscreenGameRunningNow` reflects the detector. Full suite
-  **422 passed / 0 failed / 0 warnings**. Real-app reproduction still deferred to the creator.
-- **To commit later (this unit only):** the two code files + the two memory files listed above.
-- Verify with the creator first: launch while an exclusive-fullscreen game is the foreground — the
-  game must stay live and the app must open behind/alongside it without focus steal.
+- **Fix** for the scene-strip / F-key ordering report — `ViewModels/MainViewModel.Scenes.cs` new
+  `ReorderScenesToCanonical()` (canonical F1-F5 order at load, renamed scenes after; next save
+  re-stamps SortOrder) called from `MainViewModel.cs:LoadLayout`; `ytLive.Tests/SceneOrderTests.cs`
+  (new, seeds a Chat-before-BRB DB and asserts order + F1-F5 labels + persisted SortOrder).
+  See `bugs.md` entry 2026-10-10. Scope-locked files: `ViewModels/MainViewModel.Scenes.cs`,

+  `HANDOFF.md`.
+- Full suite **423 passed / 0 failed / 0 warnings**. Root cause was the creator's own DB (Chat
