In @.github/workflows/cloud-command-deadlines.yml:
- Around line 4-13: Update the pull-request path filter in the workflow to
include Sources/Cloud/CloudTuiClientPaths.swift,
CmxDeviceIDCanonicalization.swift, AtomicBooleanGate.swift, and the
CmuxFoundationAtomicsC/** input paths used by the regression scripts, so changes
to any copied dependency trigger the specialized job.
In `@cmuxTests/CloudCommandDeadlineTests.swift`:
- Line 194: Remove the absolute activeDuration wall-clock assertion from the
test, while retaining the duration values only in diagnostic output. Keep the
existing returned completion assertion, since it verifies the real finished
signal completes within the watchdog-bounded flow.
In `@cmuxTests/CloudCommandOperationTests.swift`:
- Line 18: Update CloudCommandOperationTests to inject a
CloudCommandDeadlineClock into CloudMachineLink, retain the recorder.perform
closure calling link.run with the timeout, and advance the virtual clock after
the timeout timer is registered. Preserve coverage of the production timeout
path through CloudMachineLink into CloudOperationRecorder rather than throwing
an error directly.
In
`@tests/fixtures/mobile-host-identity-cold-start/IdentityColdStartFixture.swift`:
- Around line 62-63: Update the fixture around the task group using
MobileHostIdentity so cold readers start concurrently from the cachedDeviceID
snapshot without calling prewarm first, release all readers together, and verify
exactly one defaults-mirror persistence write. Move the prewarm() call into a
separate phase and retain its dedicated coverage after the cold-race election
assertions.

… lane guard PR #12935 moved the archive bundle identity from PRODUCT_BUNDLE_IDENTIFIER to CMUX_APP_BUNDLE_IDENTIFIER / CMUX_HOST_BUNDLE_IDENTIFIER and made the manual App Store export require an extension provisioning profile, but the workflow guard still asserted the old build setting and had no extension profile, so workflow-guard-tests (and everything gated on linux-preflight) fails on main. Read the bundle id from the new setting in the fake xcodebuild, provide the extension profile fixture, and keep the profile-only installer tests free of the distribution identity. Same fix as carried by #12978. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…lane
The isolated SwiftPM fixture compiles CloudTuiPersistentResourceConnection
with -warnings-as-errors and failed on two diagnostics the app target hid:
- `performRequest(..., clock: clock)` did not open the `any Clock<Duration>`
existential because the argument was an implicit-self stored property
("type 'any Clock<Duration>' cannot conform to 'Clock'"); `self.clock`
opens it as intended.
- `persistentWirePreservesPayloadAndMutationKey` captured a `var` request in
an `async let`, a Swift 6 Sendable-capture warning that the lane promotes.

Cloud control requests can outlive their deadline when the app or its socket reader is suspended: the deadline task can remain asleep while a response arrives after the absolute deadline. Cancellation can also race a successful response and return stale data. The existing persistent machine-owned transport now keeps one request actor responsible for request IDs, cancellation, deadlines, and replies.

Hosted lanes for that head: CI run 35432039489, Cloud command deadlines run 35432039500. The tagged dev build was rebuilt from this head on the self-hostedtart-macos-15lane (reload-build run 35435303500); it launches signed in with both Cloud gates on against the tag's GCP backend.The prior regression run also exposed and was corrected: the cold-start fixture’s dependency stub did not include the production
rcvariant, so the fixture compiled zero assertions on that path. The App Store lane fixture was updated separately to match the current notification-extension bundle identity after its stale fake-tool branch omittedExportOptions.plist. The current isolated compiler repair explicitly opens the command clock existential viaself.clockand freezes a captured request before anasync let.Related to #11008. This change covers command request deadlines; the long-lived dial/handshake lifecycle is separate.
