… (issue #53) A direct model ID is a direct route on all three endpoints, /v1/messages included. Fallback triggers on any >=400 with no exception; exhaustion keeps the primary model's real status and signals via the header and body code, never 424. The hard-limit block is an HTTP 200 assistant message, not a 429. The M302 absolute is softened to the connected-route condition.
Same falsehoods as issue #53 findings 2 and 3, echoed on reference/api and reference/headers and parked in the backlog. The error-envelope example is now a real auth envelope, the status table drops 424 and reassigns 429 to the rate-limit codes, and exhaustion is described by header and body code.

…only as default The #68 audit caveat: the body code on an exhausted chain is providerCode ?? 'fallback_exhausted', so the two sentences stop promising the literal constant.

Applies the recommended options of #53 (batch pass, 2026-08-15):
/v1/messagesincluded.X-Manifest-Fallback-Exhausted: true+ body codefallback_exhausted. The 424 keyword is gone.Also consumes the two backlog echoes of findings 2 and 3 on
reference/api.mdxandreference/headers.mdx(never-halfway rule): real auth error envelope as the example, status table without 424, 429 reassigned to the rate-limit codes.Coherence: GREEN. Closes #53.
