-`AgentStatus` is `'idle' | 'running' | 'disposed'`, and `SessionId` is branded. `running` describes the driver-wide drain interval, which can span turn close, its durability checkpoint, and consecutive queued turns; it does not prove a turn is still open. `AgentOptions` is merge-extensible: core declares `provider?` and `model?` (dispatch requires both after `agent/request`), while `dsh-mode` adds `mode?` as a boundary-applied initial session-mode intent. Persona belongs to `dsh-system-prompt`: an agent-scoped `deployment:persona` may shadow the global default.

 The cause is a TypeScript-enforced same-process input. An active holder copies its discriminant into the runtime-only `AbortSignal.reason`; it is retired before `turn/end` publication. `agentInterruptReasonOf(signal)` recognizes `user`, `parent`, and lifecycle-only `disposed` without consulting ambient initiator state. Durable `turn/end` retains the coarse `{ kind: 'aborted' }` outcome; request provenance would require a separate durable event rather than overloading the terminal result.
