a90ff51d22256639ba1250a1d589f75a73c5ca9f Make ThreadSafeWeakPtr safe to mutate from different threads
not a security fix
confidence 0.15
signal score 11.06
Source/WTF/
Classified as not security-relevant.
Triage note: Redesigns ThreadSafeWeakPtr/Ref to store a ThreadSafeWeakPtrControlBlock plus int16_t object offset via ThreadSafeWeakPtrStorage, dropping TaggingTraits, and migrates RemoteAudioVideoRendererProxyManager to ThreadSafeRefCounted. Large infrastructure refactor/size optimization with a RELEASE_ASSERT_WITH_SECURITY_IMPLICATION bound check; no targeted bug fix.
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.
