fix: address review round four

- the cached-identity rung gains a finality gate: the identity value
  carries its descriptor seq and a cached row is served only when that
  seq lands in the child's own suffix, so a fork seed's replayed
  ancestor identity can never outrank the authoritative refold
  (stateVersion bumped for the state-shape change)
- the cold preparation validates the inspected header against the
  enumerated candidate's lifecycle witness; a republished id degrades to
  that child's corrupt diagnostic instead of leaking the new owner's log
- the new projection registration proves HMR disposal; companion notes
  qualify the superseded decision text and record the deliberate
  error-face asymmetry

The published logical record is also the activity source: `SessionRecord.live` means `running`, while `live: false, persisted: true` means `inactive`. Activity comes directly from the trace and causes no additional child-log load. `inactive` encodes neither successful completion nor resumability: it may describe settled one-shot history or a continuable child for which `send_message` can materialize another Activation. Conversely, `running` says only that the session is live: a live continuable Agent outside the continuation manager's matching Activation still appears as `running`, but `send_message` rejects it as an ownership conflict. A child is not visible before its session is published, and no process-local Activation entry is added as a second candidate or activity source. Listing is a snapshot that may race publication, disposal, or a later message; `send_message` remains the authoritative delivery-time operation.
The subagent service keeps `sessionQuery` optional so start and follow-up remain available without it. Its public `listChildren(parentSessionId: SessionId)` method resolves the optional service and dynamically loads the optional session-query runtime only when called; ordinary subagent imports, start, and follow-up therefore do not evaluate that package. Listing belongs directly to `SubagentService`: it interprets the query's lineage, events, and live state without resolving the Activation-based continuation manager or consulting Agent registrations, Activations, or providers, so a deployment with sessions, `subagents`, and `sessionQuery` can list even when `agents` is absent. The method throws `SubagentError` with stable code `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` before loading the runtime or doing query work when the query service is absent. `@deepseek-ai/dsh-tool-subagent-control` exports separately loadable tool plugins: the `send_message` adapter requires only `subagents`, while the `list_agents` adapter requires both `subagents` and `sessionQuery` at load. A deployment may therefore use `send_message` without installing or loading session query; the list-tool fiber remains inactive until the required service is available, while another direct service consumer receives the same explicit call-time contract.

This dependency posture — the optional `sessionQuery`, its error code, and the list tool's load requirement — is part of the superseded read path: the current codes (`SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE`, `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE`) and the narrowed load requirement live in the [superseding note](../architecture/2026-08-06-subagent-list-identity-projection.md).
`listChildren(parentSessionId, signal?)` forwards the caller's signal to `traceSession()` and the conditional exact `readEvent()` operation. `listEvents()` has no cancellation parameter, so the listing path checks the signal before and after that await and after each candidate settles. If any query operation rejects after the signal aborts, the service normalizes the result to `SubagentError` with stable code `CANCELLED`; a backend abort error or a diagnostic-mapped query error cannot escape or become a successful partial listing.

已发布的逻辑记录同时也是活动状态来源:`SessionRecord.live` 表示 `running`,而 `live: false, persisted: true` 表示 `inactive`。活动状态直接来自追踪结果,不会导致额外加载 child 日志。`inactive` 既不表示执行成功,也不表示可恢复:它可能表示已结算的一次性历史,也可能表示 `send_message` 可以为其物化另一次 Activation 的可继续 child。反过来,`running` 只表示会话存活:位于继续执行管理器对应 Activation 之外的存活可继续 Agent 仍会显示为 `running`,但 `send_message` 会将其作为所有权冲突拒绝。child 会话发布前不可见,也不会添加进程内 Activation 条目作为第二个候选来源或活动状态来源。列表查询是一份快照,可能与发布、dispose 或后续消息发生竞态;`send_message` 仍是消息送达时的权威操作。
subagent 服务将 `sessionQuery` 保持为可选依赖,因此没有该服务时仍可执行 start 和 follow-up。其公开的 `listChildren(parentSessionId: SessionId)` 方法只在被调用时才会解析这个可选服务,并动态加载可选的会话查询运行时;因此,普通 subagent 导入、start 和 follow-up 都不会触发该包求值。列表查询直接由 `SubagentService` 负责:它解释查询返回的谱系、事件和存活状态,无需解析基于 Activation 的继续执行管理器,也不会查询 Agent 注册信息、Activation 或提供方;因此,仅包含会话、`subagents` 和 `sessionQuery` 的部署即使缺少 `agents` 也能执行列表查询。如果查询服务缺失,该方法会在加载运行时或执行查询工作前抛出 `SubagentError`,并携带稳定错误码 `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE`。`@deepseek-ai/dsh-tool-subagent-control` 导出可分别加载的工具插件:`send_message` 适配器只要求 `subagents`,而 `list_agents` 适配器在加载时同时要求 `subagents` 和 `sessionQuery`。因此,部署可以在既不安装也不加载会话查询的情况下使用 `send_message`;列表工具 fiber 会在必需服务可用前保持未激活状态,而其他直接服务消费方会收到同一项明确的调用时契约。

`listChildren(parentSessionId, signal?)` 会把调用方的取消信号转发给 `traceSession()` 和条件性精确 `readEvent()` 操作。`listEvents()` 不接受取消参数,因此列表查询路径会在等待该操作的前后,以及每个候选处理完成后检查信号。如果取消信号触发后有查询操作以拒绝结算,服务会将结果归一化为 `SubagentError`,并携带稳定错误码 `CANCELLED`;后端中止错误或可映射为 diagnostic 的查询错误均不会逃逸,也不会使调用以成功的部分列表返回。
