Three things still reached the network from a container whose models were
baked in:
- tiktoken fetched cl100k_base from openaipublic.blob.core.windows.net on
every fresh container (its cache defaulted to /tmp), and token accounting
calls it on every chat. prefetch_models now warms it too; the image sets
TIKTOKEN_CACHE_DIR.
- The chunker loaded its tokenizer with Tokenizer.from_pretrained, which
revalidates the revision with a HEAD request per process start and stalls
for the etag timeout (10 s) when huggingface.co is unreachable. It now reads
tokenizer.json from the hub cache first and only downloads on a miss; the
repo-metadata read for models outside the registry does the same.
- tldextract fetched the public suffix list on the first web crawl; the
bundled snapshot is used instead.
application/scripts/verify_offline.py exercises these paths (and docling's
conversion when the extra is installed) so an image can be checked with
docker run --network none.
