Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
provenance	publisher-changed	AI (provenance): Publisher change from sebmck to hzoo reflects the well-known Babel maintainer transition (Sebastian McKenzie → Henry Zhu) in 2016.	ai	2026/04/24
phantom-deps	phantom-dep:babel-runtime	AI (phantom-deps): babel-runtime is a declared dependency referenced in config; not a security concern.	ai	2026/04/24
provenance	no-provenance	AI (provenance): Published in 2016, before Sigstore/provenance existed. Expected for legacy Babel packages.	ai	2026/04/24
