FORM OWNERSHIP
Use the platform.
Keep feedback explicit.
Own one status
The application disables submission and labels the in-flight operation with ordinary state.
Focus the correction
Server field feedback updates ARIA linkage and returns focus to the exact invalid control.
Announce the failure
Form-level service errors use a native alert while preserving every valid authored value.
Submit without re-entry
The same corrected values survive failure and succeed on the next keyboard submission.
Ship no registry
No field registration API, metadata proxy, schema adapter, or browser form runtime is introduced.
UPGRADE
Keep form ownership local.
