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.
preset/ — per-session agent composition
English | 中文
An agent preset is a directory holding one agent.cordis.yml. Mounting it under an agent's scope context gives that session its own tools and prompt sections while every other live session keeps its own, so one process can run several differently composed agents at once.

Preset vocabulary, filesystem discovery over trusted and user-authored roots, and the guarded per-agent mount | ctx.agentPresets |
persona/ |
The agent persona as a composable row, so a preset can change identity and not only tools | — |
The composition split this group assumes: registries and cross-session facilities are process singletons and stay in the host composition, while a preset carries what one agent contributes to them. A preset that names a row publishing a process-global service is rejected at mount rather than allowed to collide with the next session.
