- Around line 155-165: Update the size-wait loop around window and contentView
so it performs a minimum stabilization number of layout passes before accepting
matching sizes, while retaining the one-second deadline. Ensure later layout
mutations are still detected and preserve the existing layout invalidation and
display calls.
In `@Sources/App/ExternalApplicationWindowTracker.swift`:
- Around line 336-338: Add a test using raw window information with
kCGWindowIsOnscreen absent, then assert it produces an off-screen event and
suppresses companion presentation. Keep existing explicit-false and
preconstructed snapshot tests unchanged, and ensure the test exercises the
default behavior in the window-tracking logic.

Complete the Computer Use follow-up to #12265. Hidden windows retain their identity, missing visibility data suppresses the permission companion, and the companion moves to the active Space only when first shown.
Pass pointer-sized window IDs to
CGWindowListCreateDescriptionFromArray. The previous boxed-number array returned no records; its replacement also lost hidden windows. The corrected call requests one tracked window without a full window scan.Prevent background preference writers from waiting for main-thread observers. One shared adapter preserves synchronous main-thread delivery and schedules background callbacks on the main actor. This removes the startup circular wait captured in the XCTest process sample. All 16 affected observers use this path.
Tests now check every one of 12 onboarding layout passes, decode metadata with the visibility key absent, and check each invalid remote-terminal selector separately. The latter removes an error-order assumption while retaining both access-denial checks.
Validation:
9f68cca02bf1713c2c8e792f555d4f0ee009714d, which includes main through2965a7a55794f7e2fcba01f5b513344ef1530288.No user-facing text changed. The change addresses the shared callback boundary and the macOS data contract; it does not add retry delays.
