It tracks zoom intent, reconciles frames after display and application lifecycle events, replaces the former rescue class, and adds tests for disconnected displays, native fullscreen, and zoomed windows.

- Around line 124-125: Restore the fullscreen early return in the window frame
calculation so frames with the .fullScreen style bypass both dimension-capping
helpers, including frameByRaisingUndersizedDimensions; preserve the exact
selected display frame for native fullscreen.

Display changes could strand cmux windows off-screen or leave zoomed windows smaller than the available display. Activation, restoration, and display changes now share presentation-aware frame repair. Untrusted intermediate display snapshots preserve the current monitor; native fullscreen and Split View remain owned by AppKit except for guarded full-width topology repair.
Zoom intent survives a titlebar click and automatic display repositioning. A real move, resize, native tile, or remembered-frame restore clears it.
This PR also makes app-host CI reject assertion failures, unfinished Swift Testing runs, and zero-test results. That exposed stale fixtures and runtime failures that the previous exit-65 fallback had masked. The repairs cover:
Cloud regressions were committed before their fixes. CI reproduced loss of a pending workspace after stale metadata. An exact-source fleet probe reproduced the queued-up/revocation race before the fix; all 27 coordinator tests passed afterward.
The CI follow-up updates Cloud failure assertions to the reserved pane, supplies revision-bound automatic naming contexts, preserves daemon title provenance through restore, separates SSH authentication from PTY attachment, controls the fallback clock in address-reuse coverage, and counts group anchors in sidebar scale coverage. Dock browser focus now uses the existing owning-window reveal path and fails before changing selection when that window is unavailable. Key-window tests install the real observer on their own delegate.
Validation: Xcode project normalization, wiring for all 950 test files, discovery of 2,810 shard selectors, Swift syntax checks, and whitespace checks passed. The first focused hosted build caught a leftover fixture-helper call; that compile error is corrected. Full and focused hosted validation is pending on
df400ddc49f136801b2f96ae2f3702d43ac750e0. CI is not green: terminal focus recovery, tmux output geometry, sidebar invalidation, and four WebKit lifecycle/bridge/inspector failures still need runtime diagnosis. No new dogfood build is verified; fleet build acquisition was unavailable.Localization audit: these repairs introduce no new user-facing UI strings; existing localized messages are retained.
Physical external-monitor disconnect/reconnect and native Split View were not exercised during this CI repair run. The isolated tagged build supports follow-up dogfood.
Closes #2824. References #11822 and #11923.
Note
Medium Risk
Touches window persistence, SSH/tunnel lifecycle, session autosave, and agent hooks alongside CI behavior changes; regressions could affect display reconnect, remote workspaces, or fleet test signal.
Overview
Main window geometry now uses a shared
MainWindowFrameReconcilerwith presentation modes (ordinary, zoomed, full-width fullscreen on topology change only). Zoom intent is remembered across inactive/reconnect glitches and cleared on real user placement; CI adds focusedMainWindowZoomPlacementTests.App-host CI no longer treats exit 65 plus classifier success as green: non-zero xcodebuild status fails the shard, batches run to completion with combined failure status, and parallel testing is disabled for unit batches. Ubuntu jobs configure APT over HTTPS with a validation test.
CLI / remote shells:
vm/clouddev|layout|env defer socket connect until send; SSHControl*merging respects per-key explicit-ovs host config; persistent PTY paths opt into hangup protection while normal SSH/Mosh shells use plainexec. Agent-hook fixes cover Grok ambient dispatch, Codex monitor stack depth, legacy stop/journal idle repair, Hermes IDs inextra, and credential redaction ordering.App behavior: Browser portal owns sidebar divider drags via handoff; remote git metadata clears on first trusted remote promotion; windowless route freeze/close uses route identity; session autosave fingerprint skips lifecycle revision for live-only orphans; cloud tunnel revocation/start ordering and link-wait races; tmux sizing parity and fork watch install deduping; dock portal reconcile and restored-agent title boundaries; keyboard shortcut conflict ordering for global hotkey.
