uv run fails in Antigravity sandbox because uv touches cache metadata under ~/.cache/uv/**/.git.
These are cache sentinel files (to prevent git indexing), not real repositories.
Repro:
- Run any
uv run ...command inside Antigravity sandbox. - Observe sandbox denial on access to
~/.cache/uv/**/.git. - Same command works in Claude Code / outside Antigravity sandbox.
Expected:
uv run should succeed; cache sentinel .git access should be allowed.
Suggested fix:
Whitelist ~/.cache/uv/**/.git in sandbox policy.
