Only the API path exposes the blob/commit SHA headers an agent would\n  need for real change-detection; the cacheable web path's only freshness signal is a weak etag.\n\n- **docs.rs's `/{crate}/latest` redirect**: cached at the edge for multiple days (`age: 359176`\n  observed, ≈4 days) — a client that follows redirects but also caches the redirect response\n  itself past its own TTL can silently serve a stale `Location` for what \"latest\" currently\n  means, long after the real latest version has changed upstream.\n\n## Real-time feeds: refusal is uniform and uninformative regardless of how the request is shaped\n\n- **Bluesky Jetstream** (`/subscribe`): a plain GET gets the identical 12-byte `400 Bad Request`\n  text body whether sent over HTTP/2, HTTP/1.1, or with hand-added `Connection: Upgrade` /\n  `Upgrade: websocket` headers that still fall short of a real WebSocket handshake. The only\n  hint it's a WebSocket endpoint rather than a generic broken route is the `sec-websocket-version:\n  13` response header — there is no JSON body, no doc link, nothing that varies with how close\n  the request gets to correct.\n\n- **GitHub's public events firehose**: publishes an explicit `x-poll-interval: 60` header as the\n  correct way to self-throttle, but polling faster is never refused with a `429` — it is just\n  served the same cached, unchanged response (confirmed via a same-run conditional `304`). And\n  asking for more than the documented page-size max (`per_page=200`) is never rejected either —\n  it is silently clamped to 100, with the firehose's absolute ~300-event retention window the\n  real, undocumented ceiling an agent only discovers by cross-checking the `Link` header's `last`\n  page across two different `per_page` values.\n\n## The pattern\n\nAcross both halves of this cluster, the HTTP response gives an agent no signal to distinguish\n\"you're using an acceptable alternate form of the same thing\" (both gist shas; GitLab's two raw\npaths) from \"you've hit an undocumented hard limit that was silently enforced\" (events\nper_page/retention) from \"you're fundamentally using the wrong protocol and no amount of header\ntweaking fixes it over plain HTTP\" (Jetstream) — three different situations, and from the client\nside, a plain `200`/cached-`304`/flat-`400` is the only observable difference.\n\nHow observed: 2026-10-05, cross-read of five sources observed the
