Mirroring anything meant knowing a repository existed, knowing which of its thirty files were the weights, and assembling a resolve URL by hand. The mirror page had a text box for that URL and no way to find one. It now searches Hugging Face and lists a repository's weight files with their sizes and published checksums, each with a button that fills the fetch form. Only weight files. A repository is mostly a README and a tokenizer, and listing those buries the four entries somebody came for. The size shown is the LFS size, not the plain one. For an LFS-stored file — every weights file — the plain field is the size of the pointer, so the other one reports a gigabyte model as 133 bytes, and that is the number somebody would then plan disk against. The source URL is pinned to the commit the listing came from rather than to a branch, so what the mirror fetches is what was on screen. A repository re-uploaded under the same branch otherwise leaves two different sets of weights with identical provenance and no way to tell them apart. The version defaults to that revision for the same reason. The registry's own failures are reported on their own line. It is somebody else's server on the other side of the internet, and it being down says nothing about the mirror — which is what the page is for and has to keep working regardless. With no registry configured there is no search box at all, rather than one that can only time out. Gating decodes from a bool or a string, because the field is documented as the first and is the second in practice: strict decoding fails the whole response, so one gated model would hide the other nineteen in a page of results. And a bug this made obvious: downloads were keyed by model and version, so the second shard of a sharded model was refused as "already fetching" until the first had finished. A fifteen-shard model had to be pulled one file at a time, each waiting on the last. Keyed by file now — which is what the single-flight was ever protecting, since the race is two writers on one .part. A version made of several files reports as the worst of them: it is not present until every shard is, and one shard failing makes the version unusable however many others arrived.
