Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
provenance	publisher-changed	AI (provenance): sebmck → hzoo is the well-documented Babel maintainer transition (2016). Both are core Babel team members.	ai	2026/04/24
phantom-deps	phantom-dep:babel-runtime	AI (phantom-deps): babel-runtime is a declared dependency used via Babel's transform helpers, not direct imports. Stable for this package.	ai	2026/04/24
provenance	no-provenance	AI (provenance): Published in 2016, before Sigstore/provenance existed. No provenance expected for legacy Babel 6 packages.	ai	2026/04/24
