Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
dependencies	unvetted-dep:safe-regex-test	AI (dependencies): safe-regex-test is a well-known ljharb/inspect-js ecosystem package; its use here is legitimate and expected for this package's functionality.	ai	2026/04/21
provenance	no-provenance	AI (provenance): ljharb's packages consistently lack Sigstore provenance; this is a known pattern for this publisher and not a security concern given their strong track record.	ai	2026/04/21
