Agent Quick Fix

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

Product: Kubernetes
Current-contract area: Kubernetes 1.36 deprecates Service spec.externalIPs
Likely root cause: Upgrade warnings and policy checks fail for services relying on externalIPs.
Repair direction: Verifier checks behavior across multiple requests/build modes, not merely compilation. Check resource behavior after apply, not only schema acceptance.

Validation Status

Codex searched organically in the validation run. No no-web counterfactual is attached to this page yet.

Symptom

Upgrade warnings and policy checks fail for services relying on externalIPs.

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.

Verification

Verifier checks behavior across multiple requests/build modes, not merely compilation. Check resource behavior after apply, not only schema acceptance.

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.
