Chapter: quality
Rule: serverRefusedSubmit
Spec: Server refused submit
The UI let this submit; the server refused it. Users can pick or send a value that will not store, and only see an error after Save.
A write (POST, PUT, PATCH, or DELETE) returned 400, 409, or 422. The form offered or sent a value the API will not persist. Validate or filter before Save so the listed choice and the server agree. Not this: GET 4xx, 401/403/404, 5xx; Save that never sent (silent Save); junk that crashed the tab (Q-03); junk that stored with no field error (Q-02).
This id is stable. Reports link here so T/V/Q classes do not shuffle when a soak ranks differently.
