Harden CI: replace curl-pipe-shell with setup-uv action#7
Merged
Conversation
Replace `curl -LsSf https://astral.sh/uv/install.sh | sh` with the official astral-sh/setup-uv GitHub Action, SHA-pinned to v4. This eliminates a curl-pipe-shell pattern in a public repo where workflow files are readable by anyone.

Summary
curl -LsSf https://astral.sh/uv/install.sh | sh(line 247 ofrelease.yml) with the officialastral-sh/setup-uvGitHub Action, SHA-pinned to v4setup-uvaction is the officially recommended installation method and provides caching, version pinning, and integrity verification out of the boxWhy
Piping
curloutput directly toshin CI is a supply-chain risk — ifastral.shwere compromised, arbitrary code would execute in the workflow. SHA-pinning the official GitHub Action ensures the exact code version is immutable and auditable.
