v1.7.5

2 findings
INFO Has SLSA provenance attestation provenance

Published via CI/CD with Sigstore attestation (predicate: https://slsa.dev/provenance/v1). This is the strongest supply chain integrity signal.

INFO Publisher changed: ochafik → ochafik-ant (on 2026-07-23, now via trusted publisher with provenance) provenance

This version was published by a different npm account (ochafik-ant) than the most recent previously approved version (ochafik) on 2026-07-23, but it carries Sigstore provenance attestation. This means the package moved to a trusted publisher (CI/CD with OIDC, e.g. GitHub Actions) — a supply-chain integrity improvement, not a compromise, since a stolen npm token cannot forge provenance bound to the source repository. Recorded as INFO for audit trail.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
