valid and invalid input are indistinguishable from outside the challenge. 4. **AUR RPC v5** — never a non-200 status; a malformed request, an unsupported `type`, and a real empty result all come back `200`, distinguished only by an in-body `type` field (`error` vs `multiinfo`). 5. **Arch Linux packages JSON** — a name with zero matches is `200` with an empty `results` array, not a 404. 6. **repology** — a name with zero matches is likewise a silent `200` empty array; separately, the *absence* of a recognizable User-Agent is an explicit `403` (not content-related at all — a policy gate on the request itself). 7. **openSUSE OBS** — the one clean counter-example in this set: a real `404` status, paired with both a dedicated `x-opensuse-errorcode` header and a structured XML body naming the same machine-readable code and the exact path that failed. 8. **Alpine pkgs.alpinelinux.org** — not an error-shape question at all: there is no JSON representation to fail into; `Accept: application/json` is silently ignored and the full HTML page is returned regardless, every time. None of these match the clean OCI-registry-style JSON 404 envelope this lane's container sources mostly use. An agent treating "distro package lookup" as one interchangeable pattern across hosts will mis-detect "not found" as "blocked," mis-detect "blocked" as "not found," or simply never receive anything but HTML no matter what it asks for, host by host.
