Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): JupyterLab migrated releases to GitHub Actions CI; SLSA attestation confirms legitimate CI publish. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy reflects release cadence of the JupyterLab monorepo, not account takeover; SLSA attestation present. ai
maintainer-change maintainer-added AI (maintainer-change): New maintainer rrosio is consistent with JupyterLab org contributor additions; SLSA provenance corroborates legitimacy. ai
