The launcher checks for the workflow run up to twelve times with a fixed five-second sleep between attempts, then reports an accepted dispatch as missing. This violates the repository directive against fixed sleeps and polling for readiness in build/runtime scripts. Use a real GitHub readiness signal or a dedicated cancellation-aware retry abstraction. This repository requirement must be satisfied before merging.
Rule Used: Flag fixed sleeps, delayed dispatch, timers, polling, or wall-clock waits used as synchronization in production non-Swift app/runtime code across TypeScript, JavaScript, shell, or build/runtime scripts. Fail race repairs for lifecycle, focus, renderi... (source)

- Line 86: Update find_run and its gh run list subprocess handling so
cancellation_scope can interrupt an in-flight request: replace the blocking
check_output wait with cancellable process polling or bounded waits that observe
cancel_event, terminate the child, and exit promptly. Add a test covering a
blocked gh run list, SIGTERM cancellation, and prompt launcher exit.

scripts/run-e2e.sh cmuxTests/Suite --waitcurrently omits the ref despite promising the current branch, picks the latest workflow run even when it belongs to another caller, and exits successfully after a failed watch. That makes a focused retry unreliable as evidence for a small fix.Pin the selected source to an immutable, GitHub-accessible commit before dispatch. By default this is clean local HEAD;
--refresolves a remote branch/tag/SHA once. Match the resulting run using a unique dispatch ID and preserve the hosted failure exit status. Reject malformed selectors/options before dispatch, disable recording for app-host unit selections, and expose the existing job-timeout input (45 minutes by default, including compilation).Uses the existing manual
test-e2e.ymlworkflow. It runs one suite or method; it still compiles the test bundle and does not replace full CI or reuse earlier test results. The workflow's existing positive-execution guard rejects zero-test passes.Usage after this workflow change lands:
--workflow-ref ci-focused-app-host-testsselects this PR's workflow definition before merge; source selection remains independently pinned. No hosted run was dispatched during local validation.Validation: the first commit reproduces the old behavior with executable fake-GitHub-CLI tests (15 failed assertions and one error). All 11 tests pass after the fix, including overlapping runs, delayed discovery, missing/ambiguous runs, dirty/unpushed defaults, remote refs, malformed inputs, and failed watches. Existing selected-test execution tests (8), self-hosted workflow guards, actionlint, Bash syntax, and diff checks pass. CI tooling only; no app build. Hosted integration remains pending.
Overlap: #10024 introduces a different validated dispatcher. This PR deliberately uses its exact
dispatch_idworkflow field/run-title format, fixes the existing command, and adds immutable revision selection; it does not copy that PR's docs/policy changes or source-parser validation.Related: #13095.
