Follows #14244 (merged). It fixes the five items the #14237 review raised for switching owned pools on. Everything stays dormant: nothing changes until CI_PR_POOL_OWNED is 1.

(a) Re-run of failed jobs

"Re-run failed jobs" reuses attempt 1's changes outputs. The failed jobs therefore went back to the owned pool, and nothing watched them, because the rescue follows attempt 1 only.

  • A persistent choice now also outputs retry_runner: the Blacksmith pool the same rule picks on the lane's Xcode, which is the Xcode the owned label names.
  • Every PR macOS runs-on (compile admission, tests-build-and-lag, CLI pipe, remote daemon, Claude wrapper) reads github.run_attempt > 1 && inputs.pr_retry_runner first.
  • So do the app-host shards, which otherwise inherit compile admission's pool.
  • retry_runner is empty for a Blacksmith pick, so those runs re-run where they ran.

(b) Count each run's real peak

  • The picker step moves after the suite choice.
  • It computes this run's peak macOS jobs from its routing: the Claude wrapper, CLI pipe and remote daemon lanes, beside the larger of compile admission alone or what follows it. A full suite is up to 11 (seven shards plus tests-build-and-lag); a changed-suites run is one shard.
  • CI_OWNED_POOL_JOBS_PER_RUN is removed.
  • The rescue marker becomes macos-pool-persistent-<run>-<attempt>-<jobs>-<pool>, and the rescue matches it by prefix.
  • With CI_PR_POOL_OWNED=1, the janitor lists the artifacts of each run that may hold an owned pool: attempt 1, same repository, and no macOS job on another pool.
    • It writes a per-pool committed count: the sum over those runs of max(declared peak, jobs seen).
    • The picker counts max(running + queued, committed) as taken, so a run whose later jobs don't exist yet still holds their machines.
  • Runs created since the snapshot are placed as needing one machine but charged 11. A miscount therefore leaves minis idle; it never queues a job on them.

(c) Persistent-compile route request

Moot: #14232 retired the pilot and removed the route request step from main.

(d) Janitor on owned pools, documented

  • Stale PR runs (category b) are cancelled there on every sweep, whatever the queue.
  • The other categories cancel only while more than CI_JANITOR_QUEUE_THRESHOLD jobs are queued on the pool.
  • The docs also describe the marker listing.

(e) Bad CI_OWNED_POOL_SLOTS entries warn

While owned pools are on, each bad entry raises a ::warning:: and a summary line: not JSON, not an object, a label that isn't owned, or a count that isn't a positive whole number.

Guard

check_owned_pools_route_through_picker also covers:

  • retry_runner, which may feed only macos_pr_retry_runner
  • pr_retry_runner, which must be written exactly one way
  • the marker name
  • the guarded retry branch of the Claude wrapper's runs-on

Verification

  • Passing locally: test_ci_pr_runner_pool.py (63), test_ci_queue_janitor.py, test_ci_owned_pool_rescue.py, test_ci_self_hosted_guard.sh, and actionlint.
  • A read-only subagent review found one blocking bug: the janitor skipped the marker of any run with a macOS job on another pool, and swift-package-tests always sits on Blacksmith beside a full suite. Fixed in the second commit: every attempt-1 same-repository CI run is now a candidate.
  • The same commit pages artifact listings past 100, and maps an owned-pool admission to the macOS 26 pool in app_host_test_rerun.py.
  • The review found test_ci_change_areas.py failing on CmuxMobileAnalytics/Probe.swift; it fails the same way before this PR.

Summary by cubic

Fixes the owned-pool review items from #14237 before the fleet is switched on. Everything stays dormant until CI_PR_POOL_OWNED is 1.

  • A re-run of failed jobs, and jobs an owned runner refused at job start, now move to a Blacksmith pool named at pick time instead of the unwatched owned pool; a refused run is cancelled and its failed jobs re-run, keeping what passed.
  • A run's peak macOS jobs are computed from its routing (12 for a full suite, 2 for a CLI-only run, including cli-product-tests) and set against the pool's committed load, replacing CI_OWNED_POOL_JOBS_PER_RUN. Runs replayed since the snapshot are charged 4 machines; a miscount leaves minis idle, never queues a job.
  • The janitor reads each candidate's declared peak into a committed count and cancels stale runs on owned pools every sweep.
  • Bad CI_OWNED_POOL_SLOTS entries warn in workflow and step summary while owned pools are on.

Written for commit 4e2b3c2. Summary will update on new commits.

Review in cubic

Summary by CodeRabbit

  • Bug Fixes
    • Pull request reruns now route failed macOS jobs to a compatible retry runner, including when an owned runner refuses a job at startup.
    • When a runner refuses a job, only failed jobs are rerun; successful job results are reused.
    • Owned Mac pool capacity estimates now account for each run’s expected peak usage and committed capacity.
    • Stale pull request runs on owned Mac pools can be cleared regardless of queue depth.
    • Invalid owned-pool capacity entries now produce a workflow warning; reruns avoid persistent pools.
  • Documentation
    • Updated guidance on Mac pool availability, capacity, and rerun behavior.

📝 Walkthrough

Walkthrough

The changes update owned macOS pool sizing, commitment tracking, pull-request retry runner selection, and refusal rescue. The picker calculates run demand from workflow routing. The janitor reads persistent-pool markers. Later pull-request attempts can use a selected retry runner, and refused owned-runner jobs can be retried as failed jobs.

Changes

Owned macOS pool routing

Layer / File(s) Summary
Run sizing and pool selection
.github/workflows/ci.yml, scripts/ci/pr_runner_pool.py, docs/ci-runners.md, tests/test_ci_pr_runner_pool.py
The picker calculates each run’s peak from routing flags and compares that demand with available owned-pool capacity. The changes job runs pool selection after suite routing. Invalid slot entries generate warnings.
Persistent-pool markers and janitor snapshots
.github/workflows/ci-queue-janitor.yml, scripts/ci/queue_janitor.py, docs/ci-runners.md, tests/test_ci_pr_runner_pool.py
Marker artifacts include the run’s peak and pool. When owned-pool handling is enabled, the janitor reads markers for eligible runs and includes declared demand in pool snapshots.
Pull-request re-run runner routing
.github/workflows/ci.yml, .github/workflows/ci-macos.yml, .github/workflows/cli-pipe-regressions.yml, .github/workflows/remote-daemon.yml, scripts/ci/app_host_test_rerun.py, docs/ci-runners.md, tests/test_ci_change_areas.py, tests/test_ci_pr_runner_pool.py, tests/test_ci_self_hosted_guard.sh, tests/test_seed_derived_data.py
Persistent-pool choices provide a Blacksmith retry runner. Pull-request workflows use it on later attempts. Tests and guard validation check the runner expressions and workflow inputs.
Owned-runner refusal rescue
.github/workflows/ci-owned-pool-rescue.yml, scripts/ci/owned_pool_rescue.py, tests/test_ci_owned_pool_rescue.py
The rescue watcher detects qualifying owned-runner refusals. It cancels an unfinished run when needed and re-runs only failed jobs after confirming the pull-request head has not moved.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 4e2b3

Owned-pool runs can be admitted without enough machines, and refusal rescue can leave interrupted independent jobs out of the retry. Resolve or explicitly accept these risks before enabling owned pools.

Full details: Docstring Coverage

Explanation

Docstring coverage is 23.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 100 functions across 10 files. (1 skipped: 1 unsupported.)

Full details: Cmux No Hacky Sleeps

Explanation

The PR adds a wall-clock retry heuristic in scripts/ci/owned_pool_rescue.py. REFUSAL_SECONDS = 120 makes refused() classify a failed owned-pool job by (completed_at - started_at), and the watcher then triggers rerun_failed. This uses elapsed time to mask the runner lock/shared-state race described in the new code. The existing polling sleeps were not changed, but this new refusal outcome materially expands their retry behavior. Tests cover the heuristic, but they do not provide a readiness or refusal event.

Resolution

Remove the duration-based refusal classification. Make the runner or job-start hook publish an explicit refusal signal that the rescue script can consume, such as a documented job conclusion or step/result marker. Trigger rerun_failed only from that signal. If a timeout remains necessary, implement it through a cancellation-aware retry abstraction with a bounded deadline and tests, rather than using job duration as a proxy for runner readiness.

Review of #14252: the janitor skipped the marker of any run with a macOS
job on another pool, and swift-package-tests always runs on Blacksmith
beside a full suite, so full-suite runs on an owned pool were counted
at their current jobs, not their peak. Every attempt-1 same-repository
CI run is now a candidate. The janitor and the rescue page through a
run's artifacts instead of reading only the first 100, and the app-host
test rerun maps an owned-pool admission to the macOS 26 pool, whose
Xcode is the lane pin the owned label carries.

Review of #14252 at 439d9f5:

1. cli-product-tests (new on main since #14211) inherits compile
   admission's pool like the app-host shards, so it now reads
   pr_retry_runner first too.
2. run_jobs counted neither cli-product-tests nor the compile admission a
   CLI-only run pays for. A full suite peaks at 12 machines, a CLI-only
   run at 2.
3. An owned runner that refuses a job (glaeda's job-started hook exits 1
   on a held host lock) fails it in seconds, and GitHub never retries.
   The rescue now treats a job on the persistent pool that failed within
   120 s with no workflow step succeeded as refused: it checks the head,
   cancels the run if still going, and re-runs the failed jobs, which
   take retry_runner on Blacksmith and keep what passed.
4. A run replayed since the snapshot is charged 4 machines (a compile-only
   run with every side lane) instead of 11, now that a miscount is
   refused or queued and moved by the rescue instead of stranding a job.

(a) A re-run of failed jobs reuses attempt 1's changes outputs, so it
went back to the owned pool with no watcher. A persistent choice now
also names retry_runner, the Blacksmith pool the same rule picks on the
lane's Xcode, and every pull request macOS runs-on (and the app-host
shards) takes it from attempt 2 on.

(b) The picker now runs after the suite choice and counts this run's
peak macOS jobs from its routing (up to 11 for a full suite) instead of
CI_OWNED_POOL_JOBS_PER_RUN, which is removed. The rescue marker carries
the peak and pool; with owned pools on, the janitor reads it into a
per-pool committed count, so a run whose later jobs do not exist yet
still holds their machines. Runs replayed since the snapshot are charged
the largest peak, so a miscount leaves minis idle instead of queueing.

(c) An owned-pool run never publishes a persistent-compile route
request.

(d) The janitor's behavior on owned pools is documented.

(e) Bad CI_OWNED_POOL_SLOTS entries each raise a workflow warning and
a summary line while owned pools are on.

The guard's picker route check covers the retry runner and the marker
name. Everything stays dormant until CI_PR_POOL_OWNED is 1.

tests/test_seed_derived_data.py evaluates compile admission's runs-on
with its own Actions expression subset, which could not parse the
`github.run_attempt > 1` that pr_retry_runner added, and failed the
workflow guard tests. It now compares <, >, <= and >= as numbers the way
Actions coerces, the test context carries github.run_attempt, and a new
case checks that attempt 2 of an owned-pool run takes pr_retry_runner.

Also records why splitting a refused run is sound: the minis and
Blacksmith's macOS 26 images carried the same Xcode 26.6 build (17F113)
on 2026-09-24, and the slot example now shows the 12 std minis.

Main removed the route request step with the pilot, so the owned-pool
condition added for it, its test and its doc paragraph go too.

<title>Using jobs in a workflow</title>
<location>https://docs.github.com/actions/using-jobs/using-jobs-in-a-workflow</location>
<excerpt># Using jobs in a workflow Use workflows to run multiple jobs. ## Prerequisites To implement jobs in your workflows, you need to understand what jobs are. See Understanding GitHub Actions. ## Setting an ID for a job Use `jobs.&lt;job_id&gt;` to give your job a unique identifier. The key `job_id` is a string and its value is a map of the job&`#39`;s configuration data. You must replace `&lt;job_id&gt;` with a string that is unique to the `jobs` object. The `&lt;job_id&gt;` must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`. ### Example: Creating jobs In this example, two jobs have been created, and their `job_id` values are `my_first_job` and `my_second_job`. ```yaml jobs: my_first_job: name: My first job my_second_job: name: My second job ``` ## Setting a name for a job Use `jobs.&lt;job_id&gt;.name` to set a name for the job, which is displayed in the GitHub UI. ## Defining prerequisite jobs Use `jobs.&lt;job_id&gt;.needs` to identify any jobs that must complete successfully before this job will run. It can be a string or array of strings. If a job fails or is skipped, all jobs that need it are skipped unless the jobs use a conditional expression that causes the job to continue. If a run contains a series of jobs that need each other, a failure or skip applies to all jobs in the dependency chain from the point of failure or skip onwards. If you would like a job to run even if a job it is dependent on did not succeed, use the `always()` conditional expression in `jobs.&lt;job_id&gt;.if`. ### Example: Requiring successful dependent jobs ```yaml jobs: job1: job2: needs: job1 job3: needs: [job1, job2] ``` In this example, `job1` must complete successfully before `job2` begins, and `job3` waits for both `job1` and `job2` to complete. The jobs in this example run sequentially: 1. `job1` 2. `job2` 3. `job3` ### Example: Not requiring successful dependent jobs ```yaml jobs: job1: job2: needs: job1 job3: if: ${{ always() }} needs: [job1, job2] ``` In this example, `job3` uses the `always()` conditional expression so that it always runs after `job1` and `job2` have completed, regardless of whether they were successful. For more information, see Evaluate expressions in workflows and actions. ## Using a matrix to run jobs with different variables To automatically run a job with different combinations of variables, such as operating systems or language versions, define a `matrix` strategy in your workflow. For more information, see Running variations of jobs in a workflow.</excerpt>

<title>Re-running workflows and jobs</title>
<location>https://docs.github.com/en/actions/how-tos/manage-workflow-runs/re-run-workflows-and-jobs</location>
<excerpt># Re-running workflows and jobs You can re-run a workflow run, all failed jobs in a workflow run, or specific jobs in a workflow run up to 30 days after its initial run. Re-runs use the privileges of the actor who initially triggered the workflow, not the privileges of the actor who initiated the re-run. The workflow will also use the same `GITHUB_SHA` (commit SHA) and `GITHUB_REF` (git ref) of the original event that triggered the workflow run. A workflow run can be re-run a maximum of 50 times. This limit includes both full re-runs and re-runs of a subset of jobs. ## Re-running all the jobs in a workflow 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Actions**. 3. In the left sidebar, click the workflow you want to see. 4. From the list of workflow runs, click the name of the run to see the workflow run summary. 5. In the upper-right corner of the workflow, re-run jobs. If any jobs failed, select the ** Re-run jobs** dropdown menu and click Re-run all jobs. If no jobs failed, click Re-run all jobs. 6. Optionally, to enable runner diagnostic logging and step debug logging for the re-run, select Enable debug logging. For more information, see Enabling debug logging. 7. Click Re-run jobs. 8. To re-run a failed workflow run, use the `run rerun` subcommand, replacing `RUN_ID` with the ID of the failed run that you want to re-run. If you don&`#39`;t specify a `run-id`, GitHub CLI returns an interactive menu for you to choose a recent failed run. ```shell gh run rerun RUN_ID ``` To enable runner diagnostic logging and step debug logging for the re-run, use the `--debug` flag. ```shell gh run rerun RUN_ID --debug ``` 1. To view the progress of the workflow run, use the `run watch` subcommand and select the run from the interactive list. ```shell gh run watch ``` ## Re-running failed jobs in a workflow 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Actions**. 3. In the left sidebar, click the workflow you want to see. 4. From the list of workflow runs, click the name of the run to see the workflow run summary. 5. In the upper-right corner of the workflow, select the ** Re-run jobs** dropdown menu, and click Re-run failed jobs. 6. Optionally, to enable runner diagnostic logging and step debug logging for the re-run, select Enable debug logging. For more information, see Enabling debug logging. 7. Click Re-run jobs. To re-run failed jobs in a workflow run, use the `run rerun` subcommand with the `--failed` flag. Replace `RUN_ID` with the ID of the run for which you want to re-run failed jobs. If you don&`#39`;t specify a `run-id`, GitHub CLI returns an interactive menu for you to choose a recent failed run. ```shell gh run rerun RUN_ID --failed ``` To enable runner diagnostic logging and step debug logging for the re-run, use the `--debug` flag. ```shell gh run rerun RUN_ID --failed --debug ``` ## Re-running a specific job in a workflow 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Actions**. 3. In the left sidebar, click the workflow you want to see. 4. From the list of workflow runs, click the name of the run to see the workflow run summary. 5. Under the &quot;Jobs&quot; section of the left sidebar, next to the job that you want to re-run, click . 6. Optionally, to enable runner diagnostic logging and step debug logging for the re-run, select Enable debug logging. For more information, see Enabling debug logging. 7. Click Re-run jobs. To re-run a specific job in a workflow run, use the `run rerun` subcommand with the `--job` flag. Replace `JOB_ID` with the ID of the job that you want to re-run. ```shell gh run rerun --job JOB_ID ``` To enable runner diagnostic logging and step debug logging for the re-run, use the `--debug` flag. ```shell gh run rerun --job JOB_ID --debug ``` ## Reviewing previous workflow runs 1.

Preserve independent jobs during refusal rescue.

When failed_only=True handles a refusal while the run is active, rescue() cancels the run and then calls rerun_failed. An independent job interrupted by that cancellation has a cancelled conclusion. GitHub's endpoint reruns failed jobs and their dependent jobs, so that independent job can remain absent from attempt 2. Use a full rerun when cancellation interrupts independent work, or wait for that work to finish before calling rerun_failed.

In `@scripts/ci/owned_pool_rescue.py` around lines 391 - 393, Update the refusal
rescue flow in rescue() so cancellation cannot leave independent jobs absent
from the retry: when cancelling an active run, use a full rerun or wait for
independent work to finish before calling rerun_failed. Preserve failed-only
reruns when cancellation has not interrupted independent work.
