Send rpc.superseded with the newly active hash before activation returns.
Add an opt-in SDK hook and drain helper that closes SDK listeners and idle
connections without cancelling active handlers or background work.
Document the additive notice and preserve existing grace, stop and restart rules.
Cover immediate notices, ignored notices, early service restarts, SDK draining
and duplicate-hook diagnostics.

- /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.
- The serve loop ends the process after EOF or exit_after_response,
also with background tasks or listeners.
- One schema generator per direction for the whole document, so types
with the same name get distinct names.
- The agent gives the complete error (code, message, data) to the
model, writes SKIP only after a successful request, caps tool output
at 64 KiB, writes each history line in one write, and skips a damaged
line.
- Endpoints skip blank and non-RPC lines. client_rs does not panic.
- #[must_use] on builders and the lock guard; #[schemars] attributes
and duplicate hooks are compile errors; raw identifiers; -32000 for
local SDK errors; x-sausage-params only for methods with params.
Part 1 fixes: complete stdout writes, buffered stdin, Rust type names
in schemas, enum variant docs, -32603 for serde errors in handlers,
crate docs and modules. End-to-end check of a generated consumer through
a fake core.
Checkpoint. Known issues, fixed in part 2: short writes on stdout,
byte-wise stdin reads, Result suffix on all result schemas, lost enum
variant docs, serde errors as invalid params, missing item docs.
Staging every write until close broke tempfile, git, and SQLite, which
expect normal files. Actors that need an atomic publish write a temporary
file and rename it; the SDK has write_atomic for that.
Imported from the spike branch, with:
- a library crate (Host API) for the CLI and the tests
- JSON test scenarios for candidates
- commit on close only for new or truncated files
- a Nix flake: nix run -- init, nix run -- run
