Source	Rule	Reason	Accepted by	When
source-diff	obfuscated-file:dist/timezone.cjs	AI (source-diff): dist/timezone.cjs is a minified timezone data file (structured GMT offset exports). Benign data bundling, not obfuscation. Stable pattern for this date/time library.	ai	2026/04/23
source-diff	obfuscated-file:dist/timezone.js	AI (source-diff): dist/timezone.js is a minified timezone data file (structured GMT offset exports). Benign data bundling, not obfuscation. Stable pattern for this date/time library.	ai	2026/04/23
source-diff	obfuscated-file:dist/timezone.d.ts	AI (source-diff): dist/timezone.d.ts is a TypeScript declaration file with timezone interface declarations. Long lines due to many declare const statements, not obfuscation.	ai	2026/04/23
