Merge Risk: 🔵 Low · up to A rare multi-parent dispatch target can block dependent macOS CI, and the new guard may miss future changes that weaken the read-only router contract.

Full details: Cmux No Hacky SleepsExplanation The PR adds fixed wall-clock polling waits to the new production build/runtime script Resolution Replace the direct sleeps and duplicated polling loops with one dedicated cancellation-aware polling/timeout abstraction. Give it a monotonic deadline, an explicit cancellation signal, and an owner state predicate for run discovery, queue readiness, and completion. Make API subprocess calls honor the remaining deadline so a hung call cannot bypass the bound. Preserve observe-only behavior so it never cancels the producer, while dispatch mode cancels the producer on timeout. Add tests with a fake clock/API that verify state-driven completion, cancellation interruption, deadline enforcement, and the distinct cancellation behavior for observer and dispatcher paths. ✨ Finishing Touches 💡 2📝 Generate docstrings 💡

Inline comments:
In @.github/workflows/ci.yml:
- Around line 3232-3236: Update the persistent archive restore flow around
CMUX_COMPILE_ADMISSION_DERIVED_DATA to create the destination directory with
mkdir -p before tar extracts into it. Keep the existing archive validation and
extraction behavior unchanged.
- Around line 2974-2996: Update the dispatch payload used by the persistent
macOS compile workflow to include the return-run-details option set to true, so
api() receives the workflow run ID and does not trigger the missing-ID fallback.
Preserve the existing payload inputs and response handling.
- Around line 2947-2953: Update bounded_seconds so the accepted RUN_SECONDS
limit remains below the macos-compile-admission job’s 35-minute timeout, leaving
sufficient budget for queue polling and cleanup; clamp the upper bound to the
intended safe value such as 1500 seconds while preserving existing parsing and
default behavior.
In @.github/workflows/persistent-macos-compile.yml:
- Around line 85-90: Remove reliance on the authorize job as the trust boundary
for the persistent compile runner used by compile. Apply an external execution
restriction, such as a workflow-restricted runner group, a required-reviewer
deployment environment, or an ephemeral runner reset between jobs, while
preserving the existing compile behavior.
In `@scripts/ci/compile-app-host-test-product.sh`:
- Line 69: Update the xcodebuild invocation to safely expand the empty
module_cache_setting array under Bash 3.2 with set -u, while preserving its
existing arguments when populated; use the established module_cache_setting
symbol and keep the change scoped to this expansion.
In `@scripts/ci/run-persistent-mac-compile.py`:
- Around line 152-159: Update quarantine_state and the surrounding
persistent-state workflow to prune old apple-build quarantine directories and
obsolete Glaeda cache generations while preserving the active generation and
entries within the configured retention window. Reuse existing cache-key
structure and retention settings where available, and ensure cleanup is bounded
and safely limited to the intended .glaeda/apple-build state.
In `@tests/test_ci_self_hosted_guard.sh`:
- Line 1230: Update check_persistent_compile_lane to validate that
workflow_dispatch is the only trigger key, rejecting workflow_call and any other
listed events rather than relying on the current partial rejection pattern.
Preserve the existing dispatch-only workflow expectation.
- Line 1249: The test currently detects an empty permissions block only within a
job; update check_persistent_compile_lane to also assert the workflow-level
permissions: {} block. Keep authorize’s explicit contents: read and
pull-requests: read permissions unchanged, and retain the existing compile-level
validation.

- Around line 3063-3090: Mark the “Measure hosted queue-to-start” step with
continue-on-error: true so failures from its metrics-only gh api request do not
block the required admission gate or ci-status.
In @.github/workflows/persistent-macos-router.yml:
- Line 133: Update the workflow step invoking persistent_mac_route.py to bind
all request outputs, including pr_number, head_repository, head_ref,
author_association, head_sha, source_sha, source_tree, and source_parent1,
through the step env and reference those variables in the command instead of
template expansion. Preserve the strict SHA regex validation, and similarly bind
the workflow run ID and attempt to environment variables before using them.
In `@scripts/ci/persistent_mac_route.py`:
- Line 271: Guard the cancel call in the producer-timing-unavailable branch with
args.observe_only, matching the existing queue-timeout and execution-budget
branches. In the flow handling created or started being None, invoke cancel(api,
run_id) only when observation-only mode is disabled, while preserving the
existing fallback return.
In `@tests/test_ci_self_hosted_guard.sh`:
- Around line 1292-1314: Strengthen the persistent router assertions in the test
around workflow and permissions validation by parsing the YAML structure and
comparing exact allowlists: require only the intended workflow_run trigger
configuration, require jobs.route.permissions to contain exactly the approved
Actions write, contents read, and pull-requests read grants, and reject extra
triggers or permissions. Also validate the checkout action’s ref mapping
specifically rather than accepting any unrelated ref: main occurrence, while
preserving the existing observe-only requirement.

This pilots one lane only:
macos-compile-admissionDebug compilation for trusted same-repository pull requests..github/workflows/persistent-macos-router.ymlruns from the default branch viaworkflow_run; it alone receivesactions: write, revalidates the live PR/source, dispatches the producer, and cancels over-budget work..github/workflows/persistent-macos-compile.ymlruns the owned Apple job in the workflow-restrictedcmux-persistent-compilerunner group. Its compile job has empty GitHub-token permissions and receives no repository secrets.macOS compile admissionjob remains the check/log/artifact owner and revalidates producer output before adoption.Glaeda contract
The producer uses the native Apple front door from teamleaderleo/glaeda#1048, pinned to
ffb2af668e1be3637df2e8df4ec42085ccd3b89c.Glaeda owns persistent DerivedData, SourcePackages, module cache, and Xcode compilation-cache state. Direct native execution now accepts an expected Git commit/tree plus a clean-source requirement and rechecks that source under the Apple build lock before execution and again at completion. The #1048 head is already an ancestor of Glaeda
main; its Verify and Linux acceptance runs succeeded.cmux additionally revalidates:
Package.resolvedand recursive submodule identity;Dirty, interrupted, quarantined, incompatible, or stale state takes a cold-reset path. The wrapper keeps one whole-store quarantine snapshot and restarts Glaeda's normal base generation; hot cache contents grant zero pass authority.
Fallback and rollout
The repository selector is reversible:
Unset/off means hosted-only. Fork/untrusted PRs never publish a route request. The default-branch router and PR observer both use bounded waits; a producer miss, queue timeout, execution timeout, runner loss, validation mismatch, or artifact failure leaves hosted compile admission live.
Enabling the selector also requires the org runner group to restrict workflow access to:
manaflow-ai/cmux/.github/workflows/persistent-macos-compile.yml@refs/heads/mainThat admin gate stays off until the code/evidence lands.
Measurement
Every admission publishes a small metrics artifact and job summary with:
hot,partially-warm,cold-reset, orhosted-fallbackclassification.Hosted control from real cmux PR #13240, run 35517207443 / job 106095708064:
The persistent row is intentionally gated on merge + runner-group admin setup so the benchmark runs through the production contract rather than a side channel.
Scope kept out
No Release builds, signing/notarization, nightly/TestFlight, R2 product transport, Linux runners, GUI/runtime tests, or generic agent execution move to this lane.
