- /config/agent.yaml and /config/boot.yaml replace the JSON files, read
with serde_yaml_ng (also in the agent, inside WASM).
- sausage init asks nothing and reads no SAUSAGE_* variables. It writes
commented templates with an example for each API, and prints the path
to edit. Until the agent is configured, agent.chat names the missing
field. allow_no_token: true permits a local model without a key.
- The agent speaks openai-chat-completions, the format of OpenRouter,
Ollama, and most providers. base_url follows each SDK: with /v1 for
the OpenAI shapes, without it for Anthropic.
- Checked against the proxy with glm-5.3-flash: the agent wrote, built,
and activated a counter plugin in 55 s.
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.
- /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).
