Write new journal entries under logs/core and merge read-only legacy
history without moving SQLite/WAL files. Atomically spool failed batches,
retaining unspoolable entries for event-driven retries. Journal full trap
diagnostics before UTF-8-safe status display. Port session overflow archives
and followable line/byte excerpts to the still-shipped embedded agent.
Document retention/recovery and cover the contracts with regressions.
Include one rustfmt-only normalization in the existing SDK WASI test.

- thinking (off, low, medium, high, xhigh, max) is an enum: serde rejects
unknown levels in the config, and the schema of agent.chat lists them.
reasoning_effort, a second name for the same setting, is gone.
- agent.chat takes an optional thinking level for one turn.
- off really switches thinking off: OpenAI gets the effort none, and
Anthropic gets disabled thinking (newer Claude models think by
default). A model that cannot switch thinking off gets low.
- Unset means the model's default. Anthropic thinking blocks now return
unless thinking is off, because newer models think by default.
- The template sets thinking: medium and shows it in each example, with
current model names.
- Checked against the proxy with gpt-6-luna, glm-5.3-flash, and
claude-haiku-5-5.
- /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.
Holds the history lock for a turn, 600 s grace period, interim texts as
core.notify. Tests with a fake LLM in the real core. The SDK tests of
/proc, /self, /run, and detached notifications now run.
Host:
- test first: a new version is tested where it lies; only an installed
version goes to versions/, and instances run from there
- data/ and public/ are shared by all versions; no snapshots; rollback
restores code only
- no re-delivery, status.json, list, remove/archive, smoke test, data/
hiding, or stdin timeout; rollback needs a version
- supervisor.rs split out; one place for installing a version
- init only writes the agent folder; run installs it like any actor
- console: @actor, text to the agent, /help, /quit
Agent:
- every text goes out as a broadcast; 5-line prompt; 5 tools that describe
themselves; turn.json only marks an active turn
Docs: PROTOCOL.md, README.md, DECISIONS.md, AGENTS.md rewritten.
Examples: only notes and notes-v2.
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
