not a security fix confidence 0.08 signal score 12.54 Source/JavaScriptCore/runtime
Classified as not security-relevant.
Triage note: Implements CSS Module Scripts (import ... with { type: 'css' }) behind CSSModuleScriptsEnabled: new SourceProviderSourceType/ScriptFetchParameters::Type::CSS, createCSSModuleScript synthetic module, and module-loader signatures broadened from JSSourceCode* to JSValue. Feature work; the makeModule dynamicDowncast and scope.release() changes support it.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
