JDevlieghere

Summary

JDevlieghere's recent activity is entirely in JSC, and within it narrowly scoped to the WebAssembly debugger: instance-scoped addressing in the remote-debug protocol (the `qWasmGlobal` packet form), instance IDs backing debugger virtual addresses, and breakpoint resumption implemented by dispatching the displaced opcode. None of the work is classified as a security fix or hardening — the pattern is protocol and feature plumbing on the Wasm debug surface, not bug remediation. Where to look next: the displaced-opcode resume path, which mutates and restores live bytecode, and the debugger-virtual-address → instance translation, since both are recent rewrites of state that must stay consistent across instances.
