 ## Consequences
 
-- **Superseded in part.** Composer steering shipped afterwards, so the first Decision bullet and the first consequence below no longer describe master: `InputMachine` carries the `queue`/`steer` mode union again and Web users can steer. The [context-source and steer marks decision](../feature/2026-08-04-web-context-source-and-steer-marks.md) then supplied the product decision this note's reintroduction clause required and restored the `插话` caption on steering bubbles. Host steering ownership, `ConversationService.send`'s queue-only contract, and the rejection of hiding `steering/message` from the transcript still hold.
+- **Superseded in part.** Composer steering shipped afterwards, so the first and third Decision bullets and the first consequence below no longer describe master: `InputMachine` carries the `queue`/`steer` mode union again, Web users can steer, and the steering bubble regained its user IconActions before carrying a caption again. The [context-source and steer marks decision](../feature/2026-08-04-web-context-source-and-steer-marks.md) then supplied the product decision this note's reintroduction clause required and restored the `插话` caption on steering bubbles. Host steering ownership, `ConversationService.send`'s queue-only contract, and the rejection of hiding `steering/message` from the transcript still hold.
 - Web users cannot steer from the composer or `ctx.conversation.send`; stop/cancel and Queue remain the only mid-turn controls.
 - Host-wire and non-Web clients can still steer; the Web client shows those messages without labeling them as interjections.
 - Reintroducing a dedicated steer UI would need a new product decision; do not revive the mode union or badge without one.

-- **部分被取代。** composer steering 在此之后落地，因此 Decision 的第一条与下面的第一条后果都已不再描述 master：`InputMachine` 重新携带 `queue`／`steer` mode 联合类型，Web 用户可以 steer。随后[上下文来源与 steer 标识决策](../feature/2026-08-04-web-context-source-and-steer-marks.md)提供了本 note 重新引入条款所要求的产品决策，并恢复了 steering 气泡上的 `插话` 标注。host 侧 steering 的归属、`ConversationService.send` 仅排队的契约，以及不在 transcript 中隐藏 `steering/message` 的取舍，仍然成立。

 - Web 用户无法从 composer 或 `ctx.conversation.send` steer；中途控制只剩停止／取消与 Queue。
 - Host 线缆与非 Web 客户端仍可 steer；Web 客户端展示这些消息时不再标成插话。
 - 若要重新引入专用 steer UI，需要新的产品决策；没有决策就不要复活 mode 联合类型或徽章。

 The session header declares and renders the session-scoped `'conversation.session.header.actions'` list beside the title, allowing feature plugins to contribute controls without entering the skeleton. The composer chain currency includes the current conversation `session`; ui-subagent selects one-shot or parent-unavailable addressed sessions for reason-specific read-only copy, while the ordinary InputBar keeps every addressed child Send-only because the continuation service exposes no public per-Activation cancellation operation and `session.cancel` would bypass its ownership.

A source that names no producer shows the role alone. The header shares the Tool calls geometry and interaction with `ToolRow` through the package-internal `DisclosureRow`, while retaining context semantics: the expanded body follows its content height up to a 141px scrolling cap, shows inline JSON for both `content` and `source`, and synthesizes no tool state, summary, or keyed toolview dispatch ([disclosure decision](../../../.agents/notes/implemented/feature/2026-07-30-web-context-injection-disclosure.md), [provenance decision](../../../.agents/notes/implemented/feature/2026-08-04-web-context-source-and-steer-marks.md)).

 A Think row stays collapsed by default and exposes live reasoning throughput without expanding the chain of thought: while its reasoning block is the streaming tail, the summary switches from the settled first line to the latest non-blank line and its one-line scrollport follows each delta to the inline end. Expanding the row removes the moving summary and leaves the full reasoning in ordinary page flow, so page reading never fights an internal follower; settlement restores the stable first-line summary at the left edge ([decision](../../../.agents/notes/implemented/feature/2026-08-02-web-thinking-tail-scroll.md)).
