What
Registers WASM modules that are loaded through
WebAssembly.instantiate(buffer),WebAssembly.compile, andnew WebAssembly.Module()so their frames get symbolicated. Those modules carry no URL, so they are registered under the synthetic script name the engine reports in stack frames (wasm://wasm/<hash>), which V8 derives from the byte length for modules above 16383 bytes. Smaller modules get a placeholder name and are matched by elimination instead.Why
Non-streaming loads (the Emscripten fallback, dynamic linking, Godot Web) produced events without
debug_meta, so uploaded debug files were never applied.Closes: #19564
