maintainer-change maintainer-removed AI (maintainer-change): Routine team change in a large open-source project; SLSA provenance attestation confirms CI/CD publication integrity regardless of individual maintainer roster changes. ai
provenance missing-githead AI (provenance): Package has SLSA provenance attestation (Sigstore) which provides stronger supply chain integrity than gitHead. The publishConfig explicitly sets provenance:true; missing gitHead is a benign CI pipeline change. ai
install-scripts install-script:postinstall AI (install-scripts): Biome's postinstall selects the correct platform-specific prebuilt binary from optional deps — standard pattern for native CLI tools, stable across versions. ai
semgrep semgrep:child-process-import AI (semgrep): execSync is used in postinstall.js solely to detect musl libc for binary selection; not a malicious use of child_process. Stable for this package. ai
provenance publisher-changed AI (provenance): Biome migrated to GitHub Actions CI/CD publishing with SLSA provenance attestation, as evidenced by publishConfig.provenance=true. This is a legitimate, documented transition — not a takeover. ai
provenance slsa-provenance AI (provenance): SLSA provenance attestation is present and expected for this package going forward; this is a positive supply chain signal. ai
