# Verified 2026-09-11: astral-sh/uv publishes GitHub build-provenance # attestations (sigstore bundle, `gh attestation verify` passes) for every # release asset — tier 2, not the tier-4 same-origin-sha256 originally # assumed in SPEC.md's draft example. Per-asset .sha256 files also exist # but aren't used here since the attestation is strictly stronger.
