The backend can emit scr_wasm_memory_construct, scr_wasm_table_construct, scr_wasm_global_construct, scr_wasm_construct_without_new, scr_wasm_module_imports, scr_wasm_module_exports, scr_wasm_module_custom_sections and scr_wasm_value_of (#1410), and scr_stream_dyn_native, scr_stream_pipe_dyn and scr_stream_unpipe_dyn (#1524). Their prototypes were in scr_wasm.c or nowhere, so the runtime ABI guard failed. They are now in scr_wasm.h and scr_stream.h, and scr_wasm.c no longer repeats the header's declarations. The speculative-hoisting test relied on `v instanceof Num` in a JavaScript function failing, which constructor-function instanceof now compiles (#1512). Its hoisted function reads the prototype through Reflect.getPrototypeOf instead, which still fences.
