Activation path (review T6R): a broken plugin or a stray file in
/plugins blocks no activation; candidates replace their own entries;
discovery has a 10 s deadline and its process is stopped after the
answer; an unchanged hash keeps plugin.prev.wasm; activations run in
their own task; the watcher is not recursive; no duplicate services;
rpc.retired waits for live processes of its version; reads and hashes
on blocking threads.
Guest I/O and per-call paths: a stdin write error is EOF, stdout and
stderr are drained before the status; stderr is lossy UTF-8 and goes
to the journal from its own reader; compiled components are freed;
shutdown starts no new processes; lock queues drop stopping processes;
compile before the admission gate; CommandPre per component;
core.unlock in order; null errors are successes; the journal thread
survives SQLite errors.
sausage init builds the agent with cargo.build; sausage without a
command creates ./world. The console reads plain lines without a
terminal. PROTOCOL.md and DECISIONS.md describe the decided rules. The
flake tests the whole workspace and checks the packaged cargo.build.
- 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.
- /proc is a core layer: core/ (PROTOCOL.md, graph.json, graph.dot,
locks.json, plugins/<name>/discover.json and client.rs) and one folder
per process (info.json, log, and its /self files).
- Locks are released only after the task ended, the store dropped, and
in-flight file operations returned.
- core.activate and core.revert with copies, discovery, compatibility
checks of imports and consumers, groups, force. An admission gate
makes the snapshot of old processes complete.
- Graph of discover documents by hash, refreshed by a file watcher.
- Upgrades: grace periods (x-sausage-grace), stop, service restarts,
rpc.retired.
- SDK plugins in the real core (cli/tests/sdk.rs).
