Pressing Escape mid-stream on an iPad handed the mouse back to iPadOS: the captured cursor was swapped for the system one and the game stopped receiving relative motion, so aiming died until you clicked back in. Two previous attempts treated that release as unavoidable and built recovery around it — a re-lock burst, then a click that re-asks. Both came back from the field unchanged, because both fought the release after it had already happened, inside the cooldown the platform applies straight after its own "let me out" gesture. The release was never unavoidable. This app had no UIKit key handling at all: every key arrives on the GameController path, which is a parallel HID feed that does not consume the UIKit event, and the only thing that ever became first responder was the video view, and only to summon the soft keyboard. So every hardware Escape reached UIKit unclaimed — and an unclaimed key press is precisely what lets the system apply its own default for that key. Apps that read a hardware keyboard the ordinary way consume the event as a side effect and never see this. So claim it. The stream controller becomes first responder while capture is engaged and takes Escape in pressesBegan/pressesEnded, passing every other press to super untouched. Escape still reaches the host on the GameController path, so in-game menus open exactly as before; only the system's own interpretation is suppressed. Scoped to captured input, so Escape keeps dismissing sheets and leaving full screen whenever the stream doesn't own the keyboard, and the deliberate ways out are untouched — Cmd-Escape and Ctrl-Opt-Shift-Q are read off the same GameController path and clear capture themselves. The recovery path stays as a backstop and is retimed to match what was measured: the old burst spent its entire budget within ~0.6 s of the drop, i.e. wholly inside the cooldown, where the answer can only be no. Retries now continue at 1.2 s and 2.4 s, and quietly — they don't hide the cursor or mute pointer motion the way the burst does, so a longer recovery costs nothing when it fails.
