并解析分层值；提供方存储原始文档。LLM（大语言模型）适配器在用户分区下将其入口配置注册为组合基础；Web 网关提供经过脱敏的分层描述符，并写入用户层。 | | `ctx.subagentModelSelection` | `core` | [`tool-subagent`](../packages/subagent/tool-subagent) | - | [`tool-subagent`](../packages/subagent/tool-subagent) | - | 拥有默认关闭的设置命名空间；Agent 作用域的委派工具会在组合新顶层 Session 时读取它。 | | `ctx.credentials` | `seam` | [`credentials`](../packages/credentials/credentials) | [`credentials-local`](../packages/credentials/credentials-local) | [`llm-deepseek`](../packages/llm/llm-deepseek), [`llm-pi-ai`](../packages/llm/llm-pi-ai), [`host-apiproxy`](../packages/host/apiproxy) | - | 配置携带对机密信息的引用；提供方拥有实际值。消费方按操作解析，因此轮换后的凭据会在紧接着的下一次请求中生效；Web 网关提供不含实际值的视图和只写存储。 | | `ctx.authorization` | `seam` | [`authorization`](../packages/credentials/authorization) | - | [`llm-pi-ai`](../packages/llm/llm-pi-ai) | - | flow 由知道如何取得某份凭据的插件注册，并以其写入的记录为键；seam 拥有这段对话与"每个键同时只跑一次尝试"的生命周期，而非协议本身。 | | `ctx.sessionTelemetry` | `seam` | [`session-telemetry`](../packages/session/session-telemetry) | [`session-telemetry-otel`](../packages/session/session-telemetry-otel) | - | - | 该 seam 捕获会话记录、进行脱敏并交给一个后端；没有其他组件消费该服务，其输出会离开当前进程。 | | `ctx.storage` | `seam` | [`storage`](../packages/storage/storage) | [`storage-json`](../packages/storage/storage-json), [`storage-sqlite`](../packages/storage/storage-sqlite) | [`storage-domain`](../packages/storage/storage-domain) | - | 各后端以不同名称并列注册；数据形态（领域优先）挂载到枢纽上，并将类型化操作转换为不透明的 KV 单元原语。 | | `ctx.storageDomain` | `core` | [`storage-domain`](../packages/storage/storage-domain) | - | [`workspace`](../packages/workspace/workspace), [`message-feedback`](../packages/feedback/message-feedback) | - | 等待所有已配置后端就绪，然后将领域形态发布为一个受生命周期约束的服务，用于类型化持久状态。 | | `ctx.messageFeedback` | `core` | [`message-feedback`](../packages/feedback/message-feedback) | - | - | - | 拥有本地逐 assistant 消息反馈、生命周期与目标校验、逐条目 compare-and-set 及 Host 一元 Remote 契约，且不进入 Session 历史或遥测。 | | `ctx.workspaceRegistry` | `core` | [`workspace`](../packages/workspace/workspace) | - | [`api-workspace-controller`](../packages/api/workspace-controller), [`api-session-controller`](../packages/api/session-controller) | - | 通过领域设施拥有带 WorkspaceId 品牌类型的记录；稳定的 sessionIds 账户驱动 Host RPC 与
