Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance slsa-provenance AI (provenance): Package now publishes via GitHub Actions with SLSA attestation; this is the expected pattern going forward. ai
provenance publisher-changed AI (provenance): Transition from manual publish (probablyup) to GitHub Actions CI is consistent with SLSA attestation and official repo. ai
publish-pattern dormant-publish AI (publish-pattern): Long dormancy followed by CI migration with SLSA attestation; not indicative of takeover for this established package. ai
provenance no-provenance AI (provenance): Established package with long history; no provenance is common and not a risk signal here. ai

HIGH Missing gitHead — previous versions had it provenance

This version has no gitHead field linking it to a source commit, but previous versions did. This suggests the publish environment changed. Published by: GitHub Actions.

HIGH Publisher changed: probablyup → GitHub Actions (on 2026-05-21) provenance

This version was published by a different npm account than previous versions on 2026-05-21. This could indicate a legitimate maintainer transition or an account compromise.

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.
