Summary

Primarily WebCore-side web-platform conformance, with a heavy recent concentration in Web Audio — AudioWorklet lifecycle, AudioContext state transitions, k-rate AudioParam behavior, and MediaStream source nodes — alongside DOM/worker global object semantics (immutable prototypes, attribute getter receiver checks) and SVG geometry refactors. The pattern is high-volume spec-correctness work paired with WPT coverage expansion rather than dedicated security work; hardening appears as a side effect of that refactoring, e.g. routing Accelerate DSP calls in Biquad and DirectConvolver through span-based VectorMath helpers and clearing Safer CPP warnings in IPC message handling. Where to look next: the audio node teardown and lifetime bugs (processor destroyed while `process()` is still expected, source nodes outliving their tracks) are object-lifetime issues on a thread boundary between the audio render thread and main thread — good territory for use-after-free variant hunting. Enabling the back/forward cache across all web-platform-tests also widens the set of suspended-document states now exercised, which tends to surface stale-pointer bugs in anything holding page-scoped resources.
