HTTP status codes

Exact status fixtures across informational, success, redirect, client-error, and server-error ranges, plus soft 404 variants.

Fixtures for exact HTTP status behaviour. Every status route returns precisely the status its registry entry declares, with a machine-readable body marker where a body exists.

Families:

• Informational (100–103): interim responses cannot be faked from the application layer, so these are owned by supporting profile origins and declare the environment capabilities they need.
• Success (200, 204, 206) and conditional (304): the baseline page, an empty-body success, byte-range serving, and validator-driven 304s.
• Redirect statuses (300–308): each status pointing at the baseline 200 page. Only the raw status semantics live here — chain and loop behaviour belongs to the redirects category.
• Client errors (400–451) and server errors (500–511): one route per status, kept out of the default sitemap so broad crawls do not trigger retry storms.
• Soft 404s: pages that return 200 while their content claims otherwise.
