Verify the supply chain

This image is cosign-signed and carries an SPDX SBOM and a SLSA build-provenance attestation on the same digest. Check all three before you build on it:

# 1. signature — built and signed by QuenchWorks CI
cosign verify ghcr.io/quenchworks/images/yarn:1 \
  --certificate-identity-regexp 'https://github.com/quenchworks/.+' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

# 2. SLSA build provenance — which workflow built it, from what
gh attestation verify oci://ghcr.io/quenchworks/images/yarn:1 --owner quenchworks

# 3. SPDX SBOM — the package inventory
gh attestation verify oci://ghcr.io/quenchworks/images/yarn:1 --owner quenchworks \
  --predicate-type https://spdx.dev/Document

See the SBOM & provenance guide for reading the SBOM and using these checks in CI.

Yarn Classic leads: preinstalled on the yarn base, it installs the production-only dependency set and builds, then a clean node base receives only the prod node_modules and the built output.
