📝 WalkthroughWalkthroughThe runner fleet expands from 64 to 72 steady-state and burst runners. Compose adds eight runner services and credential volumes. Configuration comments and fleet validation tests now reference and enforce the 72-runner scale. ChangesRunner fleet scaling
Estimated code review effort: 2 (Simple) | ~10 minutes Mergeability Score: 🔵 Low · up to The fleet is expanded from 64 to 72, but the credential-volume contract test checks only the count and could allow a required runner volume to be replaced by an unrelated one. This is a bounded merge-readiness risk requiring a small test fix or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

configuration test to compare against the exact expected set runner-1-creds
through runner-72-creds, rather than checking only its length; preserve the
existing regex filtering and enforce contiguous identities with no missing or

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the exact credential-volume identity set.
The count assertion accepts a missing required volume plus an unrelated extra volume. For example, runner-1-creds through runner-71-creds plus runner-73-creds passes. Assert equality with runner-1-creds through runner-72-creds.
Proposed fix
volume_names = {
name for name in compose["volumes"] if re.fullmatch(r"runner-\d+-creds", name)
}
- assert len(volume_names) == 72
+ assert volume_names == {f"runner-{index}-creds" for index in range(1, 73)}This conflicts with the stated requirement to enforce contiguous runner identities.
