## On the wire

The response is a Kubernetes `Status` with `reason: SHA256Mismatch` and `code: 412`, plus `fix`, `docs` (this page) and `requestId`. `details.causes` lists the fields involved, when there are any. The CLI prints the fix and the request id; the Python SDK raises `nodus.errors.SHA256Mismatch`.
