2 findings
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

INFO Publisher changed: contrast_admin → jcolekaplan (on 2026-06-01, known maintainer) provenance

This version was published by a different npm account (jcolekaplan) than the most recent previously approved version (contrast_admin) on 2026-06-01, but jcolekaplan is listed as a maintainer on prior approved versions (matched on name). This looks like a manual publish by a known maintainer rather than a publisher change. Recorded as INFO for audit trail.
