not a security fix confidence 0.1 signal score 9.06 Source/WebCore/editing
Classified as not security-relevant.
Triage note: Caches client() into local CheckedPtr throughout Editor.cpp, wraps document()->markers()/existingAXObjectCache()/renderer() in protect(), and updates many SaferCPPExpectations files. Mechanical SaferCPP migration with no specific memory-safety bug addressed.
