- cargo.build (native): one source copy, tests under WASI, release build to /state/cargo/builds/<n>/, process groups killed on cancel. The host writes the SDK copy to /plugins/cargo/sdk/ at start. - sausage test-runner: one instance per test, in parallel, with its own mount table (empty world, package folder at its path); answers core.lock, core.unlock, core.notify, core.log. - The console: rustyline, notifications while typing, ls/cat through the process view, methods, ps, log, activate, revert, stop, kill. - core.notify on stdout is handled in order, before the response.
