 | **Ω-F5** | **The mode-switch symptom is both entry surfaces**, and it is *"nothing for 2 seconds, then everything switches"* — nothing renders until the whole synchronous body completes | Ω-W1-T1, Ω-W1-T2 |
 | **Ω-F6** | **ACCEPTED, and it is a spec amendment: separate the FX parking's UI half from its processing half.** Visibility / routing / FX-enable apply **synchronously**; per-FX offline/online **defers to a later idle tick** — *"the switch doesn't happen during playback anyway… the UI is the priority when toggling modes"* | Ω-W1-T1 |

+**SUPERSEDED — Ω-F6 and every deferred-park instruction under Ω-W1-T1 below (the new park-queue TU, its `OnTimer` drain, its `target_sources` line).** The deferral cost a SECOND undo point and could not be made to cost one: REAPER's undo surface has no append-to-point and no block held across a return to the message loop, so per-FX offline/online now runs inline in `applyMode`'s own block and the queue is deleted. The hitch is back on the switch's synchronous path, deliberately. The rest of Ω-W1-T1 (the honest undo mask, compare-before-write, `PreventUIRefresh`, the `resolve` hash map) stands as written.

 **Verified by Daniel, not a fork:** the deck knob-spacing defect is in the **Trigger** face.
 **Gate is correct and must stay pixel-identical** — an acceptance criterion of Ω-W1-T4, not a
 hope.
