request_failed
HTTP as raised§9.1 Transport, authentication, and tenancy
Fallback for any other framework-raised HTTP error, so no response escapes without a code.
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.
