+Tool-time context—including async `inject()` and post-tool `additionalContexts`—settles after results. Steering drains before `agent/post-step`, which sees durable output, results, context, and steering. Leftovers queue. Terminal `agent/turn-stop` remains authoritative through close/flush; later steering is discarded while queued prompts remain.

 Pruning precedes summaries; overflow retries require durable progress. Bounded transient retries compose on `agent/request-error`; cancellation wins ([compaction](../.agents/notes/implemented/architecture/2026-07-10-after-call-compaction-pressure-and-overflow-recovery.md), [retry](../.agents/notes/implemented/architecture/2026-06-21-bounded-llm-request-recovery.md)).

+The turn contains failures. Adapter failures close the step before `agent/request-error`, which receives exact `Error`, `LlmFailure`, and history. Retry opens another step; success clears history; exhaustion stores failure on `turn/end`. Failed chunks commit no message/tool.

 Other failures use `agent/error`. Cancellation and disposal beat recovery; undispatched tool calls get synthetic `tool/call`/`ABORTED_BEFORE_DISPATCH` pairs. The turn signal retires before `turn/end`. Effective `cancel()` emits its typed cause before clearing queues and aborting; observers cannot veto, idle calls emit nothing, and durability records `aborted`.

+`ScopeLayer` represents one registry's complete contribution at the global or exact-scope level. A concrete layer may aggregate multiple named and anonymous tables; whole-layer emptiness lets `ScopedLayers` reclaim scoped state without discarding a sibling table.

+`ScopedLayers<L>` owns the eager global layer and lazily created exact-scope layers. Reads do not create layers: `peek(undefined)` means no overlay, while `merge()` materializes insertion-ordered global named entries followed by scoped shadows. Registrations use one context for both visibility and Cordis effect ownership, collect one synchronous undo before optional notification, return Cordis's exact disposer, and reclaim a scoped layer only when its complete `ScopeLayer` is empty.
+
+`NamedEntries<V>` supplies insertion-ordered lookup and live iteration with caller-owned duplicate errors. `AnonymousEntries<V>` gives every append a unique identity so equal values remain independent. Iteration stays live within one nonempty table generation; draining the table detaches existing iterators from later insertions. Both return idempotent exact-entry undos; the shared `EntryValues` implementation interface is not public.

+
+| token | 值 | 说明 |
+| --- | --- | --- |
+| `--font-ui` | `Inter, system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif` | 正文栈 |
+| `--font-mono` | `Menlo, Monaco, Consolas, 'JetBrains Mono', 'Courier New', sans-serif` | 代码栈；**末位不放 monospace**（防 Windows 中文回退宋体） |
+| `--fw-strong` | `600` | 粗体统一权重 |
+| `--ease` | `cubic-bezier(.4,0,.2,1)` | 唯一缓动曲线 |
+| `--dur` / `--dur-fast` / `--dur-slow` | `.2s` / `.1s` / `.3s` | 过渡三档 |
+| `--radius-s` / `--radius-m` / `--radius-l` / `--radius-bubble` / `--radius-xl` | `8px` / `12px` / `16px` / `22px` / `24px` | 圆角语义档：小控件 / 列表条目与面板内块 / 浮层 / 气泡 / 输入卡片（基线 inputWrapper 同值）；胶囊直接写 `999px` |
+| `--shadow-panel` | `0 0 1px rgba(0,0,0,.2), 0 0 4px rgba(0,0,0,.02), 0 12px 32px rgba(0,0,0,.08)` | 浮层阴影（基线 lv3） |
+| `--shadow-float` | `0 0 1px rgba(0,0,0,.24), 0 4px 12px rgba(0,0,0,.06), 0 16px 48px rgba(0,0,0,.16)` | 强浮动面板（lv3 加强档，如 RPC 调试浮层） |
+| `--shadow-card` | `0 4px 10px rgba(0,0,0,.02), 0 2px 4px rgba(0,0,0,.04)`；暗色 `none` | 输入卡片微阴影（基线：亮色同底靠边框+微影区分，暗色靠提亮底、阴影关闭） |
+
+字号与间距**不 token 化**（基线仓同款决策）：字号在组件里写 px 且**成对写行高**，常用对 16/24（气泡）、14/22（UI 默认）、12/18（辅助）；间距用 4 的倍数。
+
+## 2. 视觉基线（源自 deepseekchat）
+
+- 侧边栏：宽 `260px + 1px` 右边框（`--border-l1`）；底色 `--bg-sidebar`。
+- 侧边栏条目：高 `40px`、圆角 `--radius-m`、字号 14px；hover 底 `--hover-bg` 或 sidebar 专属灰、**选中底 `--accent-item` 且不改文字色**。
+- 侧边栏分组标题：12px / weight 500 / `--text-tertiary` / sticky 顶部（底色同侧边栏遮滚动内容）。
+- 会话列：`max-width: 840px` 居中，<1024px 降 712px。
+- 消息流：**仅用户侧有气泡**——`--bubble-bg` 底、圆角 `--radius-bubble`、padding `10px 16px`、字号 16px/24px、`max-width: calc(100% - 88px)`；**助手侧纯文档流无底色**。
+- 消息操作条：默认 `opacity: 0`，父块 hover/focus-within 淡入（`--dur` + `--ease`）。
+- 输入卡片：与会话列同宽（840px，<1024px 降 712px)居中悬浮（距底留白带）；圆角 `--radius-xl`、边框 `--border-l2`、底 `--bg-base`、阴影 `--shadow-card`；内部上下两段=textarea（16px/24px，min 2 行 max 14 行=336px，镜像 div 自增高）+ 操作行（右下嵌 34px 主圆钮）；focus 无边框/阴影变化（基线同款）。
+- 输入主按钮（拍板 2026-07-20 三连，视觉参照 Codex App）：32px 实心正圆图标钮（内联 SVG）——空闲=`--accent` 底白↑箭头「发送」，运行中原地变 `--accent-soft` 底 accent ■「停止」（同色系不告警、不用红）。**运行中锁输入**（拍板 3，取代早先 hover 菜单方案）：textarea disabled（灰、草稿内容保留可见）、无任何排队/插话菜单，停止是唯一动作；turn 结束解禁并 refocus。键盘 Enter=发送、Ctrl/Meta+Enter=换行（运行中键盘路径随锁失效）。
+- 滚动条：近隐形、hover 加深、`scrollbar-gutter: stable` 不占布局（统一走 `.scrollable`，见 §3-9）。
+- RPC 四象限方向符（官方视觉词汇，空间隐喻：上=去 server、下=来自 server；单线=unary、双线=SSE）：
+
+| 符号 | 象限 | 徽章配色 |
+| --- | --- | --- |
+| `↑` | client-request（unary 出站） | `--accent` / `--accent-soft` |
+| `↓` | server-response（unary 回包） | ok `--ok`/`--ok-soft`，error `--error`/`--error-soft` |
+| `⇟` | server-request（SSE 帧推送） | mux `--color-frame-mux`/`--frame-mux-soft`，host `--color-frame-host`/`--frame-host-soft` |
+| `⇞` | client-response（SSE 侧回应） | `--accent`/`--accent-soft` 降透明度 |
+
+## 3. 样式编码规范（review 对照打勾）
+
+1. 颜色/圆角/动效/字体栈只引 §1 token；组件 CSS 出现字面量色值即打回（渐变遮罩等特效除外，须注释说明）。
+2. 组件 CSS 禁止出现 `[data-theme]` 选择器；暗色差异只在 global.css token 表做。确需按主题换非 token 值（渐变端点等），组件定义局部 CSS 变量、主题块只覆写变量（变量桥）。
+3. 类名 camelCase；状态类用单形容词（`.active` `.show`），由 clsx 挂载：`clsx(styles.x, cond && styles.active, className)`。
+4. 对外组件必须透传 `className` 并合入根元素。
+5. 禁用 `composes`；复用靠 token 与组件抽取。
+6. `:global` 仅用于穿透第三方/跨包类名；禁止用它定义新全局类。
+7. 交互过渡一律 `var(--dur*) var(--ease)`，只过渡 opacity / transform / 背景色 / 阴影；纯 hover 展示型元素包 `@media (hover: hover)`。
+8. hover/active 底色优先用透明度制 token（叠任意海拔底色都成立），不新造实色灰。
+9. 滚动容器统一挂 global.css 的 `.scrollable` 工具类；组件内禁写 `::-webkit-scrollbar`。
+10. 媒体查询写在组件 css 尾部、贴着被覆盖规则；断点当前仅 1024px 一档（会话列降档），加第二档需先记入本文档。
+11. 动态样式 JS 侧只写 CSS 变量（`style={{'--x': v}}`），规则留在 CSS；禁止在 TSX 里拼接样式对象做主题/状态分支。
+12. 文字灰阶只用 `--text-primary/secondary/tertiary` 三级，不新造灰色。
+
+## 4. 文件组织
+
+- `src/style/global.css` 固定分区顺序：① token 表（`:root` + `[data-theme='dark']`）② 全局基础（box-sizing、body、button reset）③ 全局工具类（`.scrollable` 等，总数保持个位数）。
+- `*.module.css` 与组件同目录同名；一个组件一个 module 文件。
+- 类型声明用现有 `css-modules.d.ts` 通配；组件数超 20 再评估引入 tcm 生成精确 `.css.d.ts`。
+- PostCSS 特性白名单：当前**零插件**（平铺 CSS + 原生嵌套按需）；引入 nested/custom-media 需先记入本文档。
+
+## 5. 演进规则与偏离记录
+
+- **加新 token**：先进 §1 表（含暗色占位列）再在组件使用；review 见到未入表的 `--` 新变量即打回（组件局部变量桥除外）。
+- **偏离基线**：与 §2 任一常数不一致的实现，须在下方偏离表记一行（日期/项/理由）。
+- **暗色表补全验收**：`[data-theme='dark']` 覆盖 §1 全部占位列后，用 RPC 面板 + 侧边栏 + 会话流三个界面人工/截图核对一遍，无组件级主题选择器即达标。
+
+| 日期 | 偏离项 | 理由 |
+| --- | --- | --- |
