uv sync --extra cuda can fail on Windows with failed to rename ... Access is denied (os error 5) when antivirus (Defender) locks the ~2.4GB torch wheel in uv's cache during extraction. Reproduced on Win11 Build 26200. The plain-pip path (pip install torch torchaudio --index-url https://download.pytorch.org/whl/cu126) works, and the README documents retry / uv cache clean / cache-exclusion.
Track a cleaner fix: investigate UV_LINK_MODE, an alternate cache location, or accept as doc-only.
