Provenance

Supply chain provenance

Status for the latest visible version.

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen

license copyleft-license:AGPL-3.0-only AI (license): Scratch VM has always been AGPL-3.0; expected and stable for this package. ai
phantom-deps phantom-dep:arraybuffer-loader AI (phantom-deps): arraybuffer-loader is a webpack loader referenced in config, not directly imported in JS — stable false positive for this build-tool pattern. ai
provenance no-provenance AI (provenance): Established Scratch Foundation package; lack of Sigstore provenance is common and not a disqualifier here. ai
