Provenance

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): blink1073 (Steven Silvester) is a listed contributor in package.json and a highly trusted publisher (3732 approved packages). This is a legitimate maintainer transition within the PhosphorJS project. ai
maintainer-change maintainer-added AI (maintainer-change): blink1073 and phosphor-user are legitimate maintainers added as part of the known PhosphorJS project transition. ai
maintainer-change maintainer-removed AI (maintainer-change): Removal of 'phosphor' maintainer is consistent with the documented PhosphorJS project maintainer transition to blink1073. ai
