🐛 Bug Fixes
- Shared tokenizer cache resolution: Fix Hugging Face tokenizer resolution when a repo is only partially cached locally, preserving offline-first behavior for valid cached layouts while retrying ambiguous cached primaries once before surfacing real load errors.
🧰 DX & Maintenance
- Tokenizer resolution coverage: Expand shared tokenizer-resolution regression tests to cover root-layout tokenizers, fallback edge cases, and refresh failure handling.
