Controller compiles/applies but loses node/zone information after naive apiVersion replacement.

Agent Quick Fix

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Product: Kubernetes
Current-contract area: EndpointSlice v1 migration changes topology fields
Likely root cause: Controller compiles/applies but loses node/zone information after naive apiVersion replacement.
Repair direction: Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. 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

Controller compiles/applies but loses node/zone information after naive apiVersion replacement.

Why This Happens

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Verification

Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. 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.
