Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
maintainer-change maintainer-takeover AI (maintainer-change): Transfer to sindresorhus, one of npm's most trusted publishers. Package aligns with his existing memoization utilities (mem, mimic-function). Legitimate ownership transfer. ai
maintainer-change maintainer-added AI (maintainer-change): sindresorhus is a highly trusted publisher with 468 packages and strong approval history. Addition is part of a legitimate transfer. ai
maintainer-change maintainer-removed AI (maintainer-change): Removal of prior maintainer is consistent with a complete, legitimate ownership transfer to sindresorhus. ai
publish-pattern new-deps-added AI (publish-pattern): mimic-function is a sindresorhus package used in his other memoization utilities; its addition is expected and benign for this package. ai
