tocat-wasm-shell

A REPL for poking at a tocat WebAssembly guest without a relay: load a module, call its exports by hand, and decode the outbox after each call.

$ cargo run -p tocat-wasm-shell -- --path upper.wasm
wasm> send hello

A guest is easiest to debug this way, since there are no imports to satisfy and no relay to stand up. The usual first thing it catches is a guest handing the host offsets into its own arena rather than addresses in linear memory, which shows up as an outbox that decodes as all zeroes.
