HuggingFace-specific inputs to ModelOrigin::HuggingFace.

Fields

repo_id: &'a str

commit_sha: &'a str

hf_tags: &'a [String]

quantization_fallback: Quantization

Used when the GGUF header declares no quantization.

file_paths: Option<&'a [PathBuf]>

Ordered file paths for sharded models.

published_sampling: Option<&'a InferenceConfig>

The model author’s own recipe, if one was fetched from the base repo.

None on every path that could not or did not look — no network, a gated repo, a repo publishing no generation_config.json, or a local-file import, which has no repo to ask. All of those fall back to the reasoning tag guess exactly as before, which is why this is an Option rather than a result carrying a reason: by the time it reaches here the reason has already been logged and the decision is the same.
