swpatters

Summary

swpatters works primarily in WebCore, concentrated on focus handling: sequential focus navigation through shadow hosts, focus entering cross-origin iframes under Site Isolation, and site-specific quirks for anchor mouse-focusability, with some adjacent render-tree and process-recovery work. Nothing here is classified as a security fix, but the crash-fix shape is consistent — null dereferences reached through focus and pseudo-element style resolution, plus a stack overflow from deep chains of non-focusable shadow hosts. Systematic-variant candidate: recursive focus traversal across shadow DOM and frame boundaries, where unbounded recursion and stale/null owner pointers are the recurring failure modes.
