Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
email-domain	unclaimed-email:rome.tools	AI (email-domain): The rome.tools domain lapse affects a contributor email, not the publishing account (arcanis). Package is part of the official Yarn Berry monorepo; no realistic hijack path for this package.	ai	2026/04/24
npm-metadata	no-description	AI (npm-metadata): This is a monorepo sub-package from yarnpkg/berry; missing description is a stable characteristic, not a malicious signal.	ai	2026/04/24
provenance	no-provenance	AI (provenance): Established @yarnpkg org package published by the known Yarn maintainer; lack of provenance attestation is not a disqualifier for this package.	ai	2026/04/24
