Summary

rniwa's work concentrates in WebCore and the WebKit layer, with a sustained Site Isolation track covering cross-origin iframe behavior — undo/redo across process boundaries, scroll-offset persistence, page cache with in-flight iframe loads — alongside a navigation-policy tightening that unconditionally blocks external URLs in subframes. The hardening pattern is static-analyzer infrastructure rather than individual bug fixes: recurring safer C++ expectation updates, CheckedPtr adoption in Node's sibling pointers, UncheckedLambdaCapturesChecker enablement, and a run of NODELETE/no-delete annotations on Lock functions and on WeakPtr/ThreadSafeWeakPtr/CheckedPtr construction and destruction. Where to look next: the safer C++ expectation files are a running inventory of code still exempted from the checkers, and the no-delete annotations are assertions that those paths never free — a destructor or lock operation that can re-enter and drop the last reference would now pass unflagged.
