Summary

zakariaridouh's commit stream splits between Site Isolation — cross-origin iframe text input (IME composition, dictation), per-page media and fullscreen manager plumbing including sender-identity validation on those message handlers, and per-navigation policy propagation to subframe document loaders — and the CMake/Cocoa build system. The flagged security fixes sit largely outside that day job, concentrated in cross-process IPC surfaces reachable from the GPU and Networking processes and dominated by memory-safety bugs: use-after-free in RemoteScrollingTree's timeline registry and IDBServer's reverse cursor, out-of-bounds reads via FEComponentTransfer's CoreImage Metal kernel and an invalidated WebGPU PipelineLayout, and uninitialized-heap disclosure in a float16 pixel-conversion early return. Systematic-variant candidate: GPU-process display-list and filter replay, where singleton fallbacks on nested replay and empty- or degenerate-parameter early returns have each already yielded a distinct bug.
