The pre-load check went through AutoConfig, which reaches the network — 20 s
on the first call against 0.8 s once local — and with trust_remote_code
EXECUTES the repo own config code, another 2.7-5.6 s, to read two plain JSON
fields. A validation that can hang is not a validation.

It now reads config.json from what is already on disk (a local directory, or
the hub cache via try_to_load_from_cache) and judges from vision_config,
model_type and architectures: 0.1 ms, no network, no remote code. A model
whose config is not here yet is still not judged — the load fetches it and the
check on the loaded object decides.
