 ## Host composition
 
-The shipped ACP, TUI, and Web compositions all mount the consumer beside `ctx.sessionQuery`. TUI and Web use their existing timeout and spill policies. ACP mounts the same timeout policy and private local spill backend with the shared 50,000-byte inline threshold, so the five tools have one model-facing contract across hosts. Web also mounts the SQLite query backend at its persistence root; generic tool presentation requires no session-query-specific client plugin.
+The consumer is an opt-in plugin. The shipped ACP, TUI, and Web compositions mount `ctx.sessionQuery` for their non-model consumers but do not mount `@deepseek-ai/dsh-tool-session-query`, so their default model requests gain no query prompt or schemas. A composition that opts in also chooses whether to mount the generic timeout and spill policies; the dedicated ACP snapshot fixture mounts both and uses private local spill storage. Generic tool presentation requires no session-query-specific client plugin.

 ## Verification
 
-Package tests pin argument validation, filter translation, timestamp normalization, exact-workspace authorization, parent-filter preauthorization and oracle resistance, changed-observation rejection, service-diagnostic redaction for ordinary and adversarial unknown values, best-effort cyclic-cause logging, logger-failure containment, missing-identity behavior, hidden-boundary pruning, current-step exclusion, internal provider paging, exclusive search and parallel exact-read classification, count caps, exact-signal forwarding, abort-reason preservation, persistence cleanup quiescence, one-scan bounded batch title enrichment, projection-before-dequeue ordering, queued-work suppression, started-worker quiescence, per-header validation, title fallbacks, representative search/trace/read rendering, generic presentation, and disposable registration. Integration coverage uses the real SQLite FTS provider over live and persisted sessions. Loader and assembled-host coverage proves that ACP, TUI, and Web register the tools with timeout and spill support, while keyless assembled ACP snapshots pin the prompt guidance and schemas plus path-independent exact event-read spill and retention behavior.

 ## 宿主组合
 
-发布的 ACP、TUI 与 Web 组合都在 `ctx.sessionQuery` 旁挂载该消费者。TUI 与 Web 使用已有的超时与 spill 策略。ACP 挂载同一超时策略与私有本地 spill 后端，并采用共享的 50,000 字节行内阈值，因此五个工具在各宿主中具有同一面向模型的契约。Web 还在其持久化根目录挂载 SQLite 查询后端；通用工具表现无需会话查询专用客户端插件。
+该消费方是一个需显式启用的插件。发布的 ACP、TUI 与 Web 组合为其非模型消费方挂载 `ctx.sessionQuery`，但不挂载 `@deepseek-ai/dsh-tool-session-query`，因此其默认模型请求中不包含查询提示词或 schema。选择启用该插件的组合还要决定是否挂载通用的超时与 spill 策略；专用的 ACP 快照 fixture（测试前置数据）同时挂载这两项策略，并使用私有的本地 spill 存储。通用工具表现无需会话查询专用客户端插件。
