Summary

The standalone notification workflow rebuilds the app and tests even though CI already produces and distributes the same test product. In run 35494917252, its unit-test step took 19m26s for about 31 seconds of test execution.

Move its five suites into one focused CI step using the shared xctestrun product and test-without-building. Each suite retains a fresh host, a strict exit-status gate, and a positive-execution check. Forward Node/Bun paths into the isolated host. Exclude these suites from the tolerant broad batches and remove the existing duplicate AgentNotificationRegressionTests selector.

Move the two package warning gates into the shared Swift package job, retaining its startup-crash retry, and remove the redundant notification workflow and its obsolete trigger guard. This removes the extra app build and package job when the old workflow would have triggered. The net runner-minute saving still needs a hosted comparison.

Related: #13067 narrowed the workflow's triggers but left this duplication; #13123 handles the other duplicate suites and shard balancing; #13118 routes package selection. These changes may need reconciliation when those PRs land. #12632's app-startup fix remains independent; this uses the existing shared host-isolation wrapper.

Testing

  • Added executable workflow tests first, then the implementation in a separate commit. They fail before the migration and pass afterward.
  • Six behavioral tests cover all five product-only invocations, environment forwarding, assertion failures, startup failures, zero-test results for every suite, and both package warning gates.
  • Passed shard coverage/packing tests, CI change-area tests, self-hosted runner guards, reusable-workflow permission checks, actionlint, and git diff --check.
  • Hosted execution of the five suites is pending this PR's CI. No app runtime code changed; no app reload or UI demo is needed.

Summary by cubic

Reuses the shared CI build for the notification semantics suites so CI no longer builds the app a second time just to test them. The five suites now run once from the existing xctestrun product with test-without-building, in fresh hosts with strict pass/fail and positive-execution checks, and are removed from the tolerant broad batches. The standalone agent-notification-tests.yml workflow is removed, the duplicate AgentNotificationRegressionTests selector is dropped, and Node and Bun paths are forwarded into the isolated host.

Moves the -warnings-as-errors gates for CMUXAgentLaunch and CmuxAgentJournal into the shared Swift package job, preserving the existing startup-crash retry. Adds workflow-level tests covering every suite invocation, tool path forwarding, failure paths, zero-test results, and both package warning gates, and drops the obsolete path-trigger guard for the removed workflow. No app runtime code changes, so no app reload or UI demo is needed.

Written for commit 892ecbb. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Added dedicated CI validation for agent notification semantics and related lifecycle, feed, and background-work test suites.
    • Added stricter Swift package checks that treat compiler warnings as errors for selected packages.
    • Added support for forwarding required tool environment settings to focused test runs.
  • Tests

    • Added end-to-end coverage for notification workflow execution, failure handling, test selection, and environment configuration.
    • Ensured focused notification suites run independently from standard test sharding.

📝 Walkthrough

Walkthrough

The dedicated notification workflow was deleted. The main CI workflow now runs notification suites, package warning checks, runner-environment checks, and workflow-step regression tests.

Changes

Notification CI gate consolidation

Layer / File(s) Summary
Move notification checks into main CI
.github/workflows/agent-notification-tests.yml, .github/workflows/ci.yml, tests/test_ci_notification_semantics.py
The dedicated workflow was removed. Main CI runs five notification suites in separate app-host processes. Regression tests verify suite filters, execution counts, failure handling, and zero-test handling.
Control focused selection and package warnings
scripts/ci/cmux_unit_test_shard.py, .github/workflows/ci.yml
The five notification suites are excluded from shard packing. CMUXAgentLaunch and CmuxAgentJournal run Swift tests with -warnings-as-errors.
Forward runner tools and update CI checks
scripts/ci/run-app-host-xcodebuild.sh, tests/test_ci_app_host_xcodebuild_retry.sh, tests/test_ci_self_hosted_guard.sh
The app-host wrapper forwards TEST_RUNNER_PATH and TEST_RUNNER_BUN_INSTALL. Retry tests verify propagation. Obsolete dedicated-workflow path checks were removed.

Priority: ⬇️ Low

RetriggerConfidence Score: 5/5

The PR appears safe to merge; the previously reported tool-path forwarding problem is resolved and no new actionable issue remains.

Summary

This PR removes the redundant notification workflow and moves its focused suites and package warning gates into shared CI products.

  • Runs five notification-semantics suites once from the restored xctestrun product, using isolated hosts and positive-execution validation.
  • Excludes those suites from tolerant broad shard batches.
  • Preserves warning-as-error checks for CMUXAgentLaunch and CmuxAgentJournal.
  • Forwards Node and Bun locations into the XCTest host environment.
  • Adds executable workflow regression coverage for success, failure, startup failure, empty selection, tool forwarding, and warning gates.

Follow-up: the notification fixes are pushed in bfad3fdd64; both inline findings are addressed and their threads are resolved. The current required-check blocker is separate: GhosttyKit release check downloads Ghostty c5c31ce819… but gets checksum 4f75749a… instead of the pinned 1034ae89…; this PR changes neither the Ghostty pointer nor checksum file. linux-preflight/tests are only aggregate failures from that required check, while workflow guards passed.

The package test step now selects packages through
scripts/ci/select_package_tests.py and writes the selection under
RUNNER_TEMP. The harness ran the step without either, so the step exited
before invoking swift and the call log was never written.

Updated this branch onto current main after #13236 merged the missing CmuxFoundation imports. The earlier EmitSwiftModule failure was the #13132 process-identity move being caught by compile admission; the unrelated Reject Bundled Provider Binaries note is informational. Checks are rerunning on the corrected base.
