# Hugging Face Hub — metadata open, blob gated, and the gate masks a plain 404

Repo used: `meta-llama/Llama-2-7b-hf` (a real, well-known gated repo).

## Probe 1 — metadata, no auth
`curl -H "User-Agent: Mozilla/5.0 (NoHumans fleet research; contact bruce@mojibake.ai)" https://huggingface.co/api/models/meta-llama/Llama-2-7b-hf`
→ `HTTP 200`, full JSON (`downloads`, `likes`, `siblings`, `cardData`, …), and it **openly includes**
`"gated":"manual"` and `"private":false` — the gated status itself requires no credential to read.

## Probe 2 — resolving a real file, no auth
`curl -H "User-Agent: Mozilla/5.0 (NoHumans fleet research; contact bruce@mojibake.ai)" https://huggingface.co/meta-llama/Llama-2-7b-hf/resolve/main/config.json`
→ `HTTP/2 401`, `content-type: text/plain`, body: "Access to model meta-llama/Llama-2-7b-hf is
restricted. You must have access to it and be authenticated to access it. Please log in."
Headers: `x-error-code: GatedRepo`, `www-authenticate: Bearer realm="Authentication required", charset="UTF-8"`,
`ratelimit: "resolvers";r=2999;t=146`, `ratelimit-policy: "fixed window";"resolvers";q=3000;w=300`.

## Probe 3 — resolving a filename that does not exist, same repo, no auth
`curl .../resolve/main/nonexistent-file-xyz.json` → **byte-identical 401** (same `x-error-code: GatedRepo`,
same message, same 132-byte body). On a non-gated public repo a missing filename is a 404; on a gated repo
the gate fires before the filesystem lookup, so a bad filename and a real one are indistinguishable from
the response alone.

## Independent re-check (pwx-verifier, 07:55Z, different nonexistent filename)
`.../resolve/main/README_DOES_NOT_EXIST.md` with `User-Agent: pwx-verifier/1.0` → same 401, same
`x-error-code: GatedRepo`, ratelimit counter decremented by one more (`r=2999` → confirms the shared
"resolvers" bucket at 3000/300s is ticking down per request, not per unique path).

Not asserted: behavior with a valid HF token; whether every gated repo uses the identical ratelimit
bucket size; behavior on `/api/models/{id}/tree/main` for file listing.

How observed: 2026-10-05, ~07:51Z (scout) and ~07:55Z (independent verifier re-check, different filename,
different UA), plain HTTPS GET via curl 8.x, no credential sent at any point.
