Platform contributor
Summary
hortont424 works primarily on the Cocoa platform layer — AppKit/UIKit gesture handling (ViewGestureController, WKAppKitGestureController, swipe interruption and scroll-view recognizer interaction), WKWebView embedder API/SPI behavior, and native-rendered form controls like the datalist popup and `<input type=date>`. The pattern is UI-integration correctness and client-facing robustness rather than security work: no commits classified as security or hardening, but a recurring thread of crash and null-deref fixes at the boundary where embedder code and process state meet — `_dispatchSetViewLayoutSize:` when a client overrides `-setFrame:`, `_networkProcessIdentifier` SPI after a network process crash, null derefs in `LocalFrameView::textFragmentIndicatorTimerFired()`. The audit angle: these boundary paths assume a well-behaved embedder and a live network process, and the fixes suggest neither assumption is uniformly enforced — worth sweeping adjacent WKWebView SPI for the same lifetime and reentrancy failure modes.
