Archive 21 implemented triplets whose shipped decisions are complete and whose bodies no longer guide future work (one-off UI chrome, generator applications whose scripts are self-explanatory, superseded implementation detail, process history owned by current contracts/skills). Delete 4 rejected triplets whose premises are obsolete: the DeepReadonly proposal (dev-invariants note now carries the alternative inline), the collapse tool-owned presentation proposal (superseded by the shipped render-intent union), retire-mid-turn-steering (steering is now load-bearing across plan-mode/apiproxy/TUI), and single-session-ACP (automation-only ACP resolved the question; multi-session isolation is pinned by tests). Repair every inbound link: retarget intentional historical citations to archived paths, replace decision-current citations with the surviving authority, and fix the stale example-execute-over-tsx pointer in pnpm-workspace.yaml. Re-record pairing sidecars and seal the archive manifest (append-only; existing seals unchanged).

# Agent Note: 用户消息气泡下方的 IconActions

## 问题
|
|
|
|
聊天用户气泡下方没有操作栏。Harness 设计稿（figma `User_Bubble/message_container`）在气泡下方右对齐展示三个 IconActions——复制、在新对话中分支、编辑——与产品其他位置使用的操作栏模式一致。
|
|
|
|
## 决策
|
|
|
|
仅当 `kind: 'user'` 时，`MessageItem` 拥有这些操作。布局为纵向列（`align-items: flex-end`，间距 6px）：先是气泡，再是高度 28px 的操作行；行内间距 10px，圆形图标按钮尺寸为 28px（`IconCopyOutline16`、`IconBranchOutline16`、`IconEditOutline16`）。Tooltip 承载中文标签。操作默认保持可见；`@media (hover: hover)` 下在悬停或 focus-within 前隐藏，以便触摸／`hover: none` 设备仍能发现控件（仅靠 opacity 仍会命中测试）。
|
|
|
|
复制将气泡内拼接后的文本块写入剪贴板（`navigator.clipboard.writeText`，并以 `execCommand` 作为回退）。分支与编辑目前仅有外观、尚无处理函数——它们预留设计席位，但不发明会话 fork 或编辑重提交流程。
|
|
|
|
steering（中途引导）气泡保持仅徽章形态，不展示这些操作。
|
|
|
|
## 考虑过的替代方案
|
|
|
|
**现在就把分支／编辑接到真实的会话 fork 与草稿编辑。**本次变更不予采纳：这些产品流程尚未定稿；交付无行为按钮符合请求范围，也避免半成品的变更路径。
|
|
|
|
**在悬停外始终以 `opacity: 0` 隐藏。**因触摸不予采纳：若无 `@media (hover: hover)`，空闲 opacity 看起来空白但仍会命中测试。具备悬停能力的指针保留淡入；其他设备保持操作可见。
|
|
|
|
## 后果
|
|
|
|
用户消息立即可用复制；分支／编辑仍为可点击的占位，直至后续决策明确其行为。测试钉死三个按钮、复制载荷，以及对 steering 的排除。
