/**
 * Was this 404 body produced by Coolify's routing catch-all rather than a
 * controller?
 *
 * `routes/api.php` ends with `Route::any('/{any}', ...)` returning
 * `{ message: 'Not found.', docs: 'https://coolify.io/docs' }`. That `docs`
 * key is the signature — no controller 404 carries it — so it distinguishes
 * "this method/path is not routed" (no middleware or controller ran) from
 * "the resource does not exist". The distinction is load-bearing twice: the
 * client's v4.2 method fallback only retries routing misses, and doctor's
 * ability probe must never read a routing miss as evidence of anything.
 *
 * One definition, shared, so the client and doctor cannot drift apart —
 * doctor's api-shape check exists to verify exactly what the client does.
