The workflow triggered on all of cmuxTests/**, so almost any pull request with a test file took two more macOS runners to rerun suites that ci.yml's shards already run. Trigger on the files that define its five suites instead. The guard checks real coverage: every file that declares or extends one of those suites must match a path trigger.

These filters cover only files that declare or extend the selected suites. ClaudeBackgroundWorkNotifyTests also uses helpers such as ClaudeHookSurfaceResolutionSwiftTests.swift and ClaudeHookLiveDeliveryTargetTestSupport.swift, but those files match none of the new patterns. Changes to them previously triggered this lane through cmuxTests/**; now they only receive generic CI coverage and skip this lane’s fresh-build and fail-closed execution checks. The new guard does not catch the gap because it scans only files that declare or extend the configured suite names.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

The narrowed paths covered the suite files only. Five shared helper files they depend on now trigger the lane too, and the guard fails when a suite file names a top-level type from an uncovered cmuxTests file. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Include extension and transitive helper files in coverage.
ClaudeHookSurfaceSocketState.swift extends ClaudeHookSurfaceResolutionSwiftTests with MockSocketServerState. ClaudeBackgroundWorkNotifyTests calls the surface-resolution server that uses this state. Because helper discovery ignores extension declarations, it does not require a trigger for this file. The current workflow omits that path, so a change to it can leave the guard passing without starting this workflow.
The same gap applies to transitive nominal dependencies such as BundledCLILinkageTests. Use an explicit suite-support manifest or follow dependencies to a fixed point.

Summary
agent-notification-tests.ymltriggers on all ofcmuxTests/**, so almost any pull request that touches a test file starts it. It then takes two macOS runners to run thingsci.ymlalready runs on the same pull request:swift testforCmuxAgentJournalandCMUXAgentLaunch: both are inswift-package-tests' package list.AgentNotificationRegressionTests,AgentJournalLifecycleCenterTests,FeedWaiterRegistryTests,ClaudeBackgroundWorkNotifyTests,OpenCodeHookRegressionTests: CI run 35421373371 ran them in app-host shards 1, 2 and 6.Cost per run is a median 9 macOS minutes (p90 22) plus two waits in the macOS queue. On 2026-09-19 this workflow was 72 of 174 queued macOS jobs. It is not a required check, and its integration job failed in 25 of 40 sampled runs.
This keeps the lane and narrows when it starts: the blanket
cmuxTests/**becomes the files that define its five suites.AgentNotificationRegressionTestsis extended across eight files, so the triggers arecmuxTests/*Notification*.swift,AgentRelayTTYOwnership*,AgentDeliveryTTYBinding*,AgentJournalLifecycleCenter*,FeedWaiterRegistry*,ClaudeBackgroundWorkNotify*andOpenCodeHookRegression*. Every source path trigger is unchanged.Of the 30 in-repo pull requests behind its last 200 runs, 9 still trigger it and 21 (70%) no longer do. Those 21 touched tests unrelated to its suites and still get the same tests from CI.
Not done here, for whoever owns the lane: since CI covers everything it runs, the workflow could go entirely, moving

Narrows the
agent-notification-testsworkflow so it starts only when the test files it runs change, instead of for every change undercmuxTests/**. The old trigger wasted two macOS runners per pull request rerunning suites thatci.ymlalready covers; PRs that no longer trigger this workflow still get the same tests fromci.yml. The new triggers name the 12 suite files and 7 shared helpers those suites use, dropping about 70% of recent test-touching pull requests.A guard in
tests/test_ci_self_hosted_guard.shfails when a suite file or helper used by those suites matches no path trigger, and when acmuxTeststrigger matches a file the workflow does not run.Written for commit 985c2a2. Summary will update on new commits.
