- userland/bundle.nu builds the userland and assembles target/userland/bin
(bin names, tools.txt aliases, brush as sh and bash).
- run and sh take --userland (default SAUSAGE_USERLAND); /bin is read-only.
- The console's bash tool runs through the process table with the
conversation id; large output spills to the world's /tmp.
- sausage run starts the services supervisor.
P1 exit session (openai/gpt-6.1-sol, fresh world): write, read, edit, git
init/add/commit/diff/log, grep -rn, rg, find and a sed|sort|uniq|wc pipeline.
rg (ripgrep 15.2), grep (ours, on ripgrep's regex crates), find and xargs
(ours), sed (uutils 0.3 wrapper), diff and cmp (uutils diffutils 0.6 with -r),
fd 10.5, jaq 2.3, env and timeout. userland/spawn is a small Command-like
client of the process interface. search-test.nu: 42 cases match native tools.
- Core modules run on the host-side preview1 over the shared VFS (D41).
- wasi:http default handler in the linker; anonymous HTTPS git clone works.
Sockets stay denied until P2.
- Each process carries the conversation (from Exec, inherited by children,
shown in /proc/processes) and a host-assigned SAUSAGE_PID.
- Spawn requests choose pipe, inherit or null per stream.
- /config/services.yaml supervisor: live edits, restarts, crash limit 5/10 s,
graceful stop (stdin EOF, then kill after 5 s) (D44).
- Compile caches keyed by content; PATH=/usr/local/bin:/bin.
world.rs also carries T13's optional read-only /bin mount (D43).
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.
Preview1 state lives in the host, so Go modules (esbuild) work. esbuild bundles
byte-identical to native; uutils and QuickJS-ng file tests pass. The failed
guest-side adapter attempt (T7) moves to spikes/s7-preview1-adapter/.
Local workflow, smart-HTTP clone/fetch/push and public HTTPS clone/fetch match
native git in stdout and exit codes. Only WASI imports (wasi:http, exit-with-code).
The workspace is now host/ and vfs/. v2 crates leave the workspace as reference.
host/src/exec.rs is the contract between the process table and the harness.
