WebCore contributor
Summary
heycam works primarily in WebCore's graphics and animation surfaces — WebGL/canvas conformance expectations, OffscreenCanvas placeholder frames, and view transitions — with a secondary line in Web Inspector recording test helpers and build tooling (ninja-wrapper presets, a `--reset-author` flag for `git-webkit apply`). The pattern is test-infrastructure maintenance rather than security work: most commits rebaseline, re-enable, or adjust conformance expectations, and the behavioral changes are correctness fixes such as a lone video keyframe stalling a MediaRecorder segment, a dynamic `view-transition-name` change not repainting its element, and a render-blocked document being revealed after navigation away. Where to look next: the MessageChannel transfer tests for non-IPC-serializable types and the OffscreenCanvas placeholder-with-no-pushed-frame path both sit on object-lifetime and IPC boundaries, even though these particular commits are tests and correctness work.
