T8: sausage:process WIT (spawn, wait, kill), one store per process over the shared root, /proc/processes, /run, pipeline and cancellation groups, Exec. brush and 78 uutils commands; the shared cwd-init object sets the cwd from PWD and keeps numeric exit codes. The corpus matches native bash. T9: V8 (deno_core) runs pi-durable, pi-ai and chord; SQLite storage in <dir>/host/harness.sqlite (WAL, synchronous=FULL); file tools on the VFS, bash through Exec; resumes after SIGKILL.
