receptionist_release_input_changed
A release gate's sealed prompt inputs no longer match the receptionist draft, pinned knowledge, or structured-intelligence version. Run a fresh exact preflight rather than publishing proof for a different request.
Problem shape
Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
