WOOD: Extending a WebAssembly VM with Out-of-Place Debugging for IoT applications
summary
WOOD extends the WARDuino WebAssembly VM to implement out-of-things debugging: capture a debug session (PC, stack, globals), ship it as a binary debug-session payload to the developer machine, run and inspect locally, then send compact byte-level code or state patches back for live updates. It uses a binary chunked protocol and lightweight proxy calls for non-transferable sensors, keeps remote state safe during calls, matches Arduino/Espruino runtime speed in preliminary tests, and shows constant network overhead versus growing overhead for remote debugging.
