Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
provenance	publisher-changed-stale	AI (provenance): Old, stable publisher change; cpojer is a long-standing trusted metro maintainer.	ai	2026/07/21
maintainer-change	maintainer-added	AI (maintainer-change): Same metro-bot transition pattern across metro packages.	ai	2026/07/21
maintainer-change	maintainer-takeover	AI (maintainer-change): metro-bot is Facebook's established automation publisher for the metro monorepo, not a hijack.	ai	2026/07/21
maintainer-change	maintainer-removed	AI (maintainer-change): Individual maintainer replaced by org automation account, consistent with monorepo migration.	ai	2026/07/21
publish-pattern	new-deps-added	AI (publish-pattern): metro-source-map is a first-party sibling package in the same monorepo.	ai	2026/07/21
phantom-deps	phantom-dep:flow-enums-runtime	AI (phantom-deps): flow-enums-runtime is a runtime dep used by Flow-typed code at runtime, not directly imported in JS; stable false positive for this package.	ai	2026/04/28
publish-pattern	dormant-publish	AI (publish-pattern): Dormancy reflects upstream release cadence for facebook/metro, not account takeover; SLSA attestation confirms integrity.	ai	2026/04/28
provenance	publisher-changed	AI (provenance): Meta/facebook migrated metro packages to GitHub Actions CI publishing; SLSA attestation confirms legitimate CI origin.	ai	2026/04/28

MEDIUM Publisher changed: rafeca → metro-bot (on 2018-12-21, unremoved on npm for 2768d) provenance

This version was published by a different npm account (metro-bot) than the most recent previously approved version (rafeca) on 2018-12-21. It has since remained available on npm for 2768 days without being unpublished, which is inconsistent with an account takeover — those are typically removed by npm shortly after discovery.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
