* test(ci): cover orphaned runs in the queue janitor Runs sit queued for hours when GitHub or Blacksmith loses one job's runner assignment (runner_name empty, pool idle): PR #13988's ci-status, the 01:00Z App Store upload, a #13055 app-host shard, and ~30 runs still queued since 2026-09-13. The janitor never cancels them. These tests describe the orphan category and fail until it exists.

On 2026-09-24 that held PR #13988's required ci-status, the 01:00Z App Store upload (and with it the ios-app-store-production concurrency group), a #13055 app-host shard, and ~30 runs queued since 2026-09-13. Each sweep now also finds orphans in the runs and jobs it already fetched: a job queued with no runner for CI_JANITOR_ORPHAN_MINUTES (default 120) while a newer job on the same labels already got a runner, or anything still queued after 24h. A backed-up pool leaves its newer jobs queued too, so it never reads as orphaned. Orphans are cancelled whatever the queue length under their own cap of 5; a cancel that is refused or leaves the run in flight after 20s is followed by force-cancel, and a run GitHub refuses both ways is reported without failing the sweep. Runs with other jobs still running wait for them; release, tag and merge-queue orphans are only reported; no-janitor is honoured. Main schedules, nightly and TestFlight orphans are cancelled: ios-appstore-upload.yml only skips a revision with a successful run and an upload artifact, so the next schedule retries.

On macOS 26 the native popover closes while a sidebar row is reparented synchronously. The section now tells a positioning-view detach from a real click-away: if the same workspace reattaches in the same turn with presentation still requested, the popover is presented again without writing presented=false. A presentation generation retires the deferred close so a reused or unmounted cell cannot write back to the wrong workspace, and unmount writes back a close that is still deferred. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Shards 2, 4, 6 and 7 of the PR app-host lane now run on macOS 26, where these tests failed on every run while passing on macOS 15: - The hidden and tiny terminal-focus recovery tests activate the app host before asking AppKit for real first-responder ownership. - The Global Search chord test counts palette requests through a test-owned menu bar extra controller instead of waiting for a popover that an inactive xcodebuild host cannot present. - The Campfire hook mock server serves an accepted client on its own server task instead of dispatching back onto the contended global pool. - The glass-chrome test sets the backdrop settings to match its useGlass argument, so the bound terminal keeps the native glass root. - The geometry feedback-loop canary puts its rows in a ScrollView so the growing rows cannot resize the window and crash the test host.

…k-away The detach flag set in viewWillMove(toWindow: nil) was only cleared by a deferred close, unmount, or detach. When the popover stayed open across the reparent, the flag stayed set, and the next real click-away took the deferred path and presented the popover again. The section now clears the flag once it is back in a window with the popover still shown. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The focused macOS 26 run of fa8d583 failed globalSearchRoutesWhileCommandPaletteIsEffective on the same inactive host the chord test already works around: routing reached the palette, but the popover could not present. Both command-palette routing tests now count requests through the same substitute menu bar extra, which now installs and restores itself. The same run showed that activating the app host does not help the hidden/tiny focus-recovery tests: NSApp.isActive never became true in 10 seconds. That repair is reverted here; #13948 and #14060 own those tests. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A detach flag left by a previous session could turn the next real click-away into a deferred re-present, and a deferred close could latch the dismiss ack on the workspace a reused cell now shows. Clear the flag when a presentation starts, and on workspace reuse write the old workspace back and advance the generation. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Lane update: the app-host job on b3d3072 sat queued on the macOS 26 pool for 30+ min, so I used the time for an independent review. It found one real bug in the checklist popover fix: a detach flag left by an earlier session could turn the next real click-away into a deferred re-present. e7dec6a clears that flag when a presentation starts, and on cell reuse writes the old workspace back once and advances the generation so a pending deferred close cannot latch the dismiss ack on the new workspace. Re-review came back clear. Squash auto-merge is on, gated by the required checks. Non-blocking follow-ups noted by the review: the Campfire mock server now serves connections one at a time, which could slow the hook CLI's side connections; the layout canary should be checked to still fail on regression inside the ScrollView. |
Run 35983669007 failed only the first local-monitor-chain test: the popover did not appear within the 2 s wait, while every later popover test in the same app host presented and passed. The wait returns as soon as the window appears, so a 10 s ceiling costs nothing when it passes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

<excerpt>NSPopover | Apple Developer Documentation Skip Navigation Class # NSPopover A means to display additional content related to existing content on the screen. ``` class NSPopover ``` ## Overview The popover is positioned relative to the existing content and an anchor is used to express the relation between these two units of content. A popover has an appearance that specifies its visual characteristics, as well as a behavior that determines which user interactions will cause the popover to close. A transient popover is closed in response to most user interactions, whereas a semi-transient popover is closed when the user interacts with the window containing the popover’s positioning view. Popovers with application-defined behavior are not usually closed on the developer’s behalf. The system automatically positions each popover relative to its positioning view and moves the popover whenever its positioning view moves. A positioning rectangle within the positioning view can be specified for additional granularity. Popovers can be detached to become a separate window when they are dragged by implementing the appropriate delegate method. ## Topics ### Accessing a Popover’s Content View Controller The view controller that manages the content of the popover. ### Managing a Popover’s Position and Size Specifies the behavior of the popover. func show(relativeTo: NSRect, of: NSView, preferredEdge: NSRectEdge) Shows the popover anchored to the specified view. The rectangle within the positioning view relative to which the popover should be positioned. ### Managing a Popover’s Appearance The appearance of the popover. The appearance that will be used when the popover is displayed onscreen. Specifies if the popover is to be animated. The content size of the popover. The display state of the popover. A Boolean value that indicates whether the window created by a popover’s detachment is automatically created. ### Closing a Popover Attempts to close the popover. Forces the popover to close without consulting its delegate. ### Getting and Setting the Delegate var delegate: (any NSPopoverDelegate)? The delegate of the popover. ### Constants The appearance and disappearance behavior of a popover. class let closeReasonUserInfoKey: String The`userInfo` key containing the reason for the willCloseNotification. Values that specify the reason for the willCloseNotification notification. The set of predefined appearances for a popover. Deprecated ### Notifications class let willShowNotification: NSNotification.Name Sent before the popover is shown. class let didShowNotification: NSNotification.Name Sent after the popover has finished animating onscreen. class let willCloseNotification: NSNotification.Name Sent before the popover is closed. class let didCloseNotification: NSNotification.Name Sent after the popover has finished animating offscreen. ### Initializers ### Instance Properties A Boolean value that indicates whether the content view of the popover extends into the arrow region. ### Instance Methods Shows the popover anchored to the specified toolbar item. ### Structures ## Relationships ### Inherits From ### Conforms To ## See Also ### Popovers A set of optional methods that a popover delegate can implement to provide additional or custom functionality.

<location>https://developer.apple.com/documentation/AppKit/NSVisualEffectView?language=objc</location>
<excerpt># NSVisualEffectView A view that adds translucency and vibrancy effects to the views in your interface. ``` class NSVisualEffectView ``` ## Overview Use visual effect views primarily as background views for your app’s content. A visual effect view makes your foreground content more prominent by employing the following effects: - Translucency and the blurring of background content adds depth to your interface. - Vibrancy is a subtle blending of foreground and background colors to increase the contrast and make the foreground content stand out visually. The material and blending mode you assign determines the exact appearance of the visual effect. Not all materials support transparency, and materials apply vibrancy in different ways. The appearance and behavior of materials can also change based on system settings, so always pick a material based on its intended use. For example, use the `NSVisualEffectView.Material.sidebar` material when your view serves as the background of your window’s sidebar. Don’t select materials based on the apparent colors they impart on your interface. AppKit creates visual effect views automatically for window titlebars, popovers, and source list table views. You don’t need to add visual effect views to those elements of your interface. ### Choosing a Translucency Effect for Your View For visual effect views you create yourself, use the `blendingMode` property to specify how and where you want the translucency applied. - Behind-window blending uses the content behind the window as the background for your visual effect view. Behind-window blending makes your entire window stand out above other windows and apps on the desktop. Sheets and popovers use behind-window blending. - In-window blending uses the window’s content as the background for your visual effect view. Typically, you use in-window blending with scrolling content, so that the scrolled content remains partially visible under other parts of your window chrome. Toolbars always use in-window blending. ### Enabling Vibrancy for Foreground Content The presence of a visual effect view in your view hierarchy does not automatically add vibrancy to your content. For custom views, you must explicitly enable vibrancy by overriding the `allowsVibrancy` property and returning doc://com.apple.documentation/documentation/Swift/true. > Note: > AppKit views and controls automatically add vibrancy where appropriate. For example, `doc://com.apple.appkit/documentation/AppKit/NSTextField` enables vibrancy to increase the contrast between the text and background. Don’t change the vibrancy settings of standard AppKit views and controls. It is recommended that you enable vibrancy only in the leaf views of your view hierarchy. Subviews inherit the vibrancy of their parent. Once enabled in a parent view, a subview cannot turn off vibrancy. As a result, enabling vibrancy in a parent view can lead to subviews that look incorrect if they are not designed to take advantage of the vibrancy effect. Vibrancy works best when your custom views contain grayscale content. Combining a grayscale foreground with a color background works well, because AppKit improves the contrast while only subtly changing the foreground hue. The same isn’t always true when blending two different color values. Dramatically different foreground and background hues can cancel each other out or result in colors that don’t match your original designs. Instead of defining custom grayscale color assets, consider using the built-in colors `labelColor`, `secondaryLabelColor`, `tertiaryLabelColor`, and `quaternaryLabelColor`. While typically used with text, these colors are applicable with any app content. The built-in colors represent varying levels of contrast for your content, with `labelColor` offering the most contrast, and `quaternaryLabelColor` offering the least contrast. ### Subclassing Notes If you subclass `NSVisualEffectView`: - Always call `super` if you override `doc://com.a…[truncated]</excerpt>

In the above example, the custom view adds the tracking rectangle in the viewDidMoveToWindow method instead of initWithFrame:. Although`NSView` implements the`addTrackingRect:owner:userData:assumeInside:` method, a view’s window maintains the list of tracking rectangles. When a view’s`initWithFrame:` initializer is invoked, the view is not yet associated with a window, so the tracking rectangle cannot yet be added to the window’s list. Thus the best place to add tracking rectangles initially is in the viewDidMoveToWindow method. ... You should also remove the tracking rectangle when your view is removed from its window, which can happen either because the view is moved to a different window, or because the view is removed as part of deallocation. One place to do this is the viewWillMoveToWindow: method, as shown in Compatibility Issues. ...

Resolve detached closes through explicit lifecycle state.
viewDidMoveToWindow() clears popoverAnchorDetachedWhilePresented while popoverPresenter.isShown is still true. If the detach-triggered NSPopoverDelegate.popoverDidClose(_:) callback arrives afterward, onExternalDismiss takes the click-away branch and calls presentedChange(false) for the same workspace. AppKit does not guarantee that popoverDidClose(_:) runs before viewDidMoveToWindow(), so checking !popoverPresenter.isShown during reattachment does not cover this order.
Keep the detached-close state until the close is resolved. Handle both a close callback before reattachment and a callback after reattachment. Also distinguish a genuine click-away close after successful reattachment so it still writes the presentation state closed. Use the presenter’s close-start or close-reason signal, or an equivalent explicit lifecycle transition, instead of isShown or a main-queue turn. Resolve the pending detached close on reattachment when the popover is no longer active, and preserve the existing teardown write-back paths for permanent removal.

around lines 440 - 467, Update the detached-popover lifecycle around
viewDidMoveToWindow() and onExternalDismiss so the detached-close state remains
set until the close is explicitly resolved. Handle callbacks arriving before or
after reattachment using the presenter’s close-start/reason signal or an
equivalent lifecycle transition, not isShown or a main-queue delay; resolve
pending detached closes on reattachment when the popover is inactive, while
allowing genuine click-away closes after successful reattachment to write the
presentation state closed and preserving permanent-teardown write-back paths.

The 10 s wait in 37bb6b7 did not help: run 35986561898 failed the same first local-monitor-chain test, and the log shows AppKit rejecting the popover's geometry (x and y infinity) right after the toggle. The routing tests before it now swap the menu bar extra, so this test is the first to anchor on a newly created status item, which macOS 26 places asynchronously. The popover then counts as shown but never appears, and a second toggle would only close it. The helper now closes that phantom and toggles again, up to three times, with a 3 s wait per attempt.

Merged. After e7dec6a, run 35983669007 failed only the first local-monitor-chain test. Its Search popover never appeared: AppKit logged infinite geometry because the status item was freshly created and not yet placed by macOS 26. A longer wait (37bb6b7) did not help. 5de546c closes the phantom popover and toggles again, up to 3 attempts, and run 35988736156 passed the app-host suites. An independent review of both follow-ups came back clear. |
#13988 serves each Campfire mock client on the accepting task instead of dispatching it back onto the global pool. This branch had moved the file into cmuxCLITests and added SO_NOSIGPIPE plus short-write retries to the same handler. The resolution takes #13988's structure and keeps both host-free safeguards inside serveAgentHookMockClient. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Goal
Move the two product-sharing pull-request jobs —
macOS compile admissionand the sevenapp-host unit testsshards — from the saturated Blacksmith macOS 15 fallback toblacksmith-6vcpu-macos-26.This repeats #13941's measured routing experiment on current main. That run cut the seven shards' queue from roughly 53–84 minutes to 0–35 seconds, and compile admission succeeded on macOS 26 with the existing Xcode 26.3 pin.
Repairs from the #13941 comparison
The previous full-suite comparison found five tests that passed on two Blacksmith macOS 15 controls and failed on macOS 26. This PR addresses each failure at the observed boundary:
windowIsKey=truewithappIsActive=false.presented=false.Routing
Only the #13941 pair moves:
macos-compile-admissionPR fallback: macOS 15 -> macOS 26CMUX_PRODUCT_RUNNERreceipt follows the same expressionapp-host-unit-testsPR fallback: macOS 15 -> macOS 26swift-package-testsremains onMACOS_RUNNER_DUAL_XCODEbecause it builds the SDK 15 release helper.MACOS_RUNNER_PRremains an override, so rollback is one repository-variable change.Validation
This PR is intentionally labeled
full-ci: the useful validation is the real seven-shard app-host suite on Blacksmith macOS 26, plus compile admission and the existing CI guards.The earlier macOS 26 run used for the failure census was 35844727955.
