None of these change behavior; each said something that was not true. `SessionCwdConflict`'s doc block had been left stranded above the `AgentPresetConflict` inserted under it, so one class carried a comment about the other and the second carried none. The roster comment named a `.system` directory that does not exist; the shipped root is `config/agent-presets/`, and `system` is the trust its entries carry. The real-composition test attributed the disabled `api-gateway` row to "side effects outside this process" alongside the port and the exporter. It is disabled for a different reason — the api-proxy cannot mount in this layer at all — and hiding that behind the same phrase would leave a later layer unable to tell whether the line can come out. One test claimed to refuse an adoption while asserting only that the header records the preset; it now says what it checks. `PERSONA_SECTION`/`PERSONA_ORDER` existed twice, once in the registry that declares the slot and once restated in the row that replaces it — a drift that would land a preset's persona beside the deployment's instead of shadowing it. The registry exports them now. The preset conflict message read "already runs agent preset undefined" for a session that records none, which is the shape a deployment with no roster produces; it names that case instead, with the regression that reaches it through the gateway. Finally, `PresetTree.write()` drops the `loader/config-update` the inherited method emits — recorded on the override, since a future edit-while-running flow needs its own persistence path.
core/ — product API spine
English | 中文
The session log, system-prompt assembly, tool registry, agent vocabulary, and concrete loop that form the harness's default control spine. These are product packages — the stable surface plugins and consumers build against.
| Package | Role | ctx key |
|---|---|---|
scope/ |
Scoped-context registration primitive | library — no ctx key |
session/ |
Event-sourced session log and in-memory store | ctx.sessions |
system-prompt/ |
Prompt and tool-schema assembly registry | ctx.systemPrompt |
tools/ |
Scoped tool registry and execution pipeline | ctx.tools |
agent/ |
Agent interface, registry, and event vocabulary | ctx.agents |
agent-loop/ |
Default concrete agent driver | ctx.agentLoop |
scope supplies the shared scoping primitive. agent owns the public seam, while agent-loop is its default implementation; extension plugins depend on the seam so the driver remains swappable.
Runnable compositions belong to examples/agent-spine-demo; this group owns only the swappable spine pieces.
