Do not use attempt 2 and ownership as a refusal signal.
A failed-jobs rerun reuses the attempt-1 outputs. Each listed route then selects pr_refused_retry_runner when github.run_attempt == 2 and the job is in pr_owned_jobs. An ordinary build or test failure therefore returns to the owned runner instead of pr_retry_runner.
owned_pool_rescue.py detects refusals, but ci-owned-pool-rescue.yml does not propagate a refusal-only signal into the rerun. Add that signal and require it before selecting pr_refused_retry_runner; otherwise select pr_retry_runner.
Apply the correction to these routes:

The janitor frees a run's owned machines before all its owned jobs exist.
done >= marker[1] compares a count of completed jobs with a count of machines. The marker's <jobs> value is held from place(): the side lanes plus max(1, len(after)). Jobs listed in after reuse admission's machine, so a run usually places more owned jobs than its peak. The comment's reasoning, "keeps reserving its peak until that many owned jobs have completed," only holds when the placed-job count equals the peak.
Concrete triggers:
- The budget is 1, so
owned_jobsis" admission shard-1 "and the marker says 1. Admission completes.shard-1is not created until admission finishes, soowned_jobsholds one completed job. The result isdone=1 >= 1, soreleasedis true. - The pool has 2 machines free and GUI jobs are switched off, so the run places
" admission cli-product cli-pipe "and the marker says 2. Admission andcli-pipecomplete beforecli-productis created. The result isdone=2 >= 2, soreleasedis true.
A snapshot taken in that window reports no committed machine for the run. The next picker can give the mini to another run. shard-1 or cli-product then queues on the owned pool until the rescue budget runs out.
Fix: carry the placed-job count in the marker and compare done with that count. For example, append it to the marker name (...-<jobs>-<placed>-<pool>) and parse it in owned_marker and run_marker. Alternatively, write the owned_jobs list into the marker JSON and release only when every listed key has completed.

Exercise the refused-retry branch in the rerun test.
The attempt-2 case marks admission as owned but provides no pr_refused_retry_runner. The evaluator resolves that input to None, so the expression falls back to pr_retry_runner. Add a nonempty refused-retry runner case and assert that attempt 2 selects it. Keep the empty-input fallback case.

Stacked on #14318. When an owned mini refuses a job, attempt 2 of that job now goes back to the fleet once, not straight to Blacksmith.
How
pr_runner_pool.pywritesrefused_retry_runner, set to the owned label when it picks an owned pool and empty otherwise. ci.yml passes it on asmacos_pr_refused_retry_runner, and the three reusable workflows take it aspr_refused_retry_runner.runs-on. Each job with an owned-jobs key gets a branch in front of the one it already has:github.run_attempt == 2 && contains(<owned_jobs>, ' <key> ') && <refused_retry_runner> ||.refused_retry_runneris empty, the expression falls through to today's route.changesoutputs, so attempt 2 gets the owned label. A stuck job is cancelled and re-run in full instead. That re-runschanges, the picker never takes an owned pool on attempt 2 or later, sorefused_retry_runnercomes back empty and the job goes to Blacksmith.Guard
check_owned_pools_route_through_pickernow treats the new output as another carrier of the owned label:macos_pr_refused_retry_runner.pr_refused_retry_runnerinput must be passed exactly.pull_requestcondition.check_macos_runneraccepts the shard prefix.Tests
