Use a time-based resolution boundary (UV_EXCLUDE_NEWER) in uvx to install the latest package as-of a chosen date, creating a lightweight, predictable CI upgrade cadence that balances freshness and repeatability by letting you 'bump the date' to update tools without pinning every package.

The post says the uv ecosystem’s setup defaults (astral-sh/setup-uv) currently purge PyPI wheels instead of caching them, which forces repeated downloads in GitHub Actions CI and requires workarounds—changing the default to cache would lower CI cost, latency, and external registry dependence.

Pin uvx dependency resolution to a cutoff date (set UV_EXCLUDE_NEWER and include that date in the GitHub Actions cache key) so workflows reuse cached Python tool versions deterministically and avoid repeated PyPI requests while allowing controlled upgrades by changing the date.
