No SLSA provenance npm registry signatures gitHead linked

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
dependencies unvetted-dep:fast-json-stable-stringify AI (dependencies): fast-json-stable-stringify is a stable, widely-used utility; its use in a webpack plugin is legitimate. ai
publish-pattern new-deps-added AI (publish-pattern): pretty-bytes is a legitimate utility for byte formatting; reasonable addition for a webpack plugin. ai
provenance no-provenance AI (provenance): Established Google-maintained package published well before Sigstore provenance was widely adopted; absence of provenance is expected and not a risk signal here. ai
phantom-deps phantom-dep:@babel/runtime AI (phantom-deps): @babel/runtime is a declared dependency in package.json and is a standard Babel convention-loaded runtime helper; not a real phantom dep for this package. ai
provenance publisher-changed AI (provenance): tropicadri is a known Google engineer on the Workbox team; this is a documented team transition from jeffposnick, not a compromise. ai
maintainer-change maintainer-added AI (maintainer-change): snugug is a known Workbox contributor; addition reflects legitimate team expansion in official project. ai
publish-pattern dormant-publish AI (publish-pattern): Long gap reflects major version release cycle (v5→v6); publisher has strong track record with no compromise signals. ai
