Agent Quick Fix

Repair against the current Kubernetes contract, then keep the change narrow and source-backed.

Product: Kubernetes
Current-contract area: Flow-control explicit zero changes meaning in v1
Likely root cause: After apiVersion migration, a priority level gets a different nominal concurrency value than intended.
Repair direction: Verifier checks behavior across multiple requests/build modes, not merely compilation. Check resource behavior after apply, not only schema acceptance.

Symptom

After apiVersion migration, a priority level gets a different nominal concurrency value than intended.

Why This Happens

Local code often type-checks under both old and new framework semantics; the failure depends on the installed framework version and current runtime defaults.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
