SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Transition from human publisher to GitHub Actions CI/CD is confirmed by SLSA provenance attestation; stable for this package going forward. ai
publish-pattern dormant-publish AI (publish-pattern): High-volume monorepo package; version gaps are expected, not indicative of takeover. ai
dependencies unvetted-dep:@accordproject/concerto-metamodel AI (dependencies): Sibling package in the same accordproject org; stable false positive for this package. ai
phantom-deps phantom-dep:@accordproject/concerto-codegen AI (phantom-deps): Same-org dependency; declared in package.json as a runtime dep even if not directly imported in source. ai
