Summary
Works almost entirely on Web Inspector and Web Automation/WebDriver, with the recent concentration on making inspector instrumentation work across process boundaries under Site Isolation — proxying Page and Network agents, cross-process identifier registries, and backend response-body storage. No security fixes or hardening commits in this window; the pattern is feature and protocol plumbing, but plumbing that adds new IPC message receivers and frontend-reachable backend state to the multi-process path. The audit angle: the proxying agents have already produced one MessageReceiver lifetime bug across process swaps, so receiver registration/teardown around provisional page commits and process swaps is a plausible place for sibling use-after-free issues.
