Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
source-diff	obfuscated-file:dist/esprima.js	AI (source-diff): dist/esprima.js is a standard webpack bundle of compiled TypeScript source; long lines are from bundling, not obfuscation. Stable for this package.	ai	2026/04/24
provenance	no-provenance	AI (provenance): Package predates Sigstore provenance; publisher is the original long-standing author.	ai	2026/04/24
