Add Window Layout to the utility shell with five manual actions: left half, right half, maximize, center and restore the preceding placement. Actions keep the intended app, verify the result, and preserve the previous placement when a write is refused. Optional shortcuts share window-write admission with Workspace Restore and respect Presentation and Away ownership.

Full-height windows and targets remain conservatively excluded. Halves and Maximize can be unavailable when both the Dock and menu bar auto-hide. An attempted write with excluded or unverifiable readback requires manual review. The docs and website describe these limits and distinguish the expanded source from the Sound-only v1.0.0 download.

Validation:

  • Root signed Debug build and four strict signature checks passed at source 2f1f296. All 2,205 compiled unit tests in 253 suites passed, with no exclusions. Final head 7e9595e differs only in five reviewed website files; every non-website input hash is unchanged.
  • Root independently passed 43 Window tests from frozen exact inputs. Owner 148 scoped tests, Debug and APP_STORE builds passed. Corrected Window CI 34379764603 passed.
  • Root verified 55 documentation links/anchors, all reviewed source ancestors, exact website blob parity and final diff. Final website checker passed 5 pages/65 IDs and 11 Python tests. Owner 7 unchanged-JavaScript tests passed.
  • Focused website browser checks passed at 360/390/1100px, including module anchors, keyboard disclosure/focus, overflow and FAQ parity. Root inspected the final mobile/desktop screenshots. Final combined PR CI 34396335305 passed at exact head 7e9595e, including build-and-test and website-smoke.

Native focus, shortcuts, VoiceOver, permission and physical-device acceptance remain pending. No benchmark measurements or new public binary are included. Website production must be verified after merge; the latest recorded production rate limit remains separate from preview success.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 7e959

The feature is broadly mergeable, but public release dates should be aligned and stale window handles should be pruned to avoid layout actions eventually becoming unavailable during unusually long sessions.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Prune stale .windowLayout handles before the 2,000-entry limit.

focusedWindow(in:) adds a handle for each distinct focused window. current(_:) returns nil when the process ends or the AX element becomes unavailable, but it does not remove the handle. Window Layout does not call windows(in:), which is the only path that removes terminated-app and closed-window handles. After 2,000 distinct windows, new focused windows return .unavailable.

Prune non-running applications before this guard, as windows(in:) already does. Also remove .windowLayout handles for closed or invalid windows when current(_:) fails, or enumerate the target application's AX windows before enforcing the limit. Running-application pruning alone is not sufficient.
