Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance no-provenance AI (provenance): No provenance is common for this package; no install scripts or runtime deps reduce risk. ai
maintainer-change maintainer-added AI (maintainer-change): artmllr added as maintainer is consistent with legitimate project handoff; clean track record. ai
provenance publisher-changed AI (provenance): artmllr is a known collaborator on superstruct with 86 approved versions and 774-day history; legitimate maintainer transition. ai
