 ## Decision
 
-Own the vocabulary: messages are arrays of typed content blocks (`text`, `reasoning`, `tool-call`, `tool-result`), with the union derived from the merge-extensible `ContentBlockMap` so plugins add block types via declaration merging. The same merge-extensible-map pattern types every "stringly" field (`MessageSource`, `FinishReason`, `TurnTrigger`, `TurnEndReason`). Streaming is a raw chunk protocol; `BlockAssembler` is the single shared assembly implementation. Adapters translate to provider wire formats — mapping cost lives in adapters, where it belongs.
+Own the vocabulary: user, assistant, and system messages are arrays of typed content blocks (`text`, `reasoning`, `tool-call`), with the union derived from the merge-extensible `ContentBlockMap` so plugins add block types via declaration merging. Tool results are first-class tool-role messages whose own content holds result blocks; released Session format v3 retains the historical `tool-result` content block inside a user-role wrapper, and the adjacent V3-to-V4 edge lifts that wrapper into the first-class role.

Streaming is a raw chunk protocol; `BlockAssembler` is the single shared assembly implementation. Adapters translate to provider wire formats — mapping cost lives in adapters, where it belongs.
 
 In-session context injection (`context/message`) and mid-turn steering originally rendered as tagged user-role envelopes (the system-reminder pattern) rather than a new role, so adapters carry zero burden. Both now project as plain user content with no wrapper; see [the injected-content-envelope Agent Note](../simplification/2026-07-20-unwrap-injected-content-envelopes.md). Live-adapter validation confirms this rendering for current DeepSeek behavior; a future provider-specific mismatch belongs in that adapter rather than a new canonical role.

-自主拥有词汇：消息是类型化内容块的数组（`text`、`reasoning`、`tool-call`、`tool-result`），其联合类型派生自可合并扩展的 `ContentBlockMap`，插件通过声明合并添加新的块类型。同一可合并扩展映射模式为所有「字符串化」字段提供类型（`MessageSource`、`FinishReason`、`TurnTrigger`、`TurnEndReason`）。流式输出采用原始分片协议；`BlockAssembler` 是唯一的共享组装实现。适配器负责转换为提供方的协议格式（wire format）——映射成本留在适配器中，正是它该在的地方。

 会话内上下文注入（`context/message`）和轮次中途 steering（中途引导）最初渲染为带标签的 user-role 信封（system-reminder 模式），而非引入新角色，因此适配器无需承担额外负担。如今两者都投影为无包装的普通用户内容；见[注入内容信封 Agent Note](../simplification/2026-07-20-unwrap-injected-content-envelopes.zh.md)。实际适配器验证已确认此渲染方式符合当前 DeepSeek 的行为；如果未来某提供方出现不兼容，应在该适配器内处理，而非引入新的规范角色。

 `createMessage(input)` is the canonical role-generic creation boundary. It mints a `MessageId`, detaches the supplied role, content, and source, and deep-freezes the complete value before returning it. `createUserMessage({ content, source })` fixes the user role for prompt and context producers. `createAssistantMessage({ content, source })` fixes both the assistant role and the model source kind, so model-output producers supply only content plus provider, model, and optional replay state. All creation helpers exclude an input id so callers cannot accidentally present creation as import. `freezeMessage(message)` is the separate import or transformation boundary: it detaches and deep-freezes a message whose identity already exists, without minting a replacement.
 
-The message helpers live in `dsh-llm` beside the base message vocabulary because their complete contracts depend only on that vocabulary. They use `dsh-brand`'s stateless `brandString()` constructor for `MessageId` and `dsh-util-values`'s shared `deepFreeze()` implementation after detaching input with `structuredClone()`. `createToolResultMessage()` belongs with the other creation helpers: it couples a tool call id to the exact user-role tool-result block and source without depending on session state or events. `dsh-session` consumes complete messages rather than owning their construction.

 The `Agent` interface accepts a complete `UserMessage` through `followup`, `steer`, and `inject`. These operations never allocate or return identity; they freeze an imported value whose id the caller already holds. Inbox claims and `agent/pre-step` receive that message directly. A content rewrite creates a frozen replacement with the same id, while an additional context is a separately created `UserMessage` with its own id.
