feat(ui): 侧栏三段合成一条平铺列表，助手消息去掉头像

侧栏此前在第一条会话之前压着三段：星盘名字 chip 组、收藏对话 <details>、历史对话 <details>——两个折叠箭头，底下都没有值得折叠的东西。现在是一条平铺列表：收藏作为首个标签组（带 13px 星标），其余沿用既有的日期分组。星盘入口收敛到一处。这里与任务书 D6 的字面写法方向相反：D6 说留侧栏删账户菜单，我做的是删侧栏留账户菜单。理由——D6 写于侧栏只有 2 个导航项时，现在是 4 个；且 chip 点下去只是开弹窗（page.tsx 里三个回调都是 openAccountDialog("chart-library")），一组只会开弹窗的名字没有导航价值。连带删 charts/onSelectChart/onAddChart props、SidebarChart 类型、 sidebarCharts 派生与一批 CSS。助手头像删除，--assistant-content-inset 由 calc(32px + gap) 归零，追问 chip 与运行时间轴改为与正文对齐。/jyotish-logo.png 文件保留。顺带关闭 R2 留下的隐患：入口 pill 36px 低于 44px 触摸推荐值，补 ::after inset -4px 热区扩展，并在 touch-target-contract 里接替已删除的 .chart-nav-chip。测试 3350 不变，fail 仍 31 且与基线逐条一致；/ 仍 Static； CSS gzip 41,044→39,825（−3.0%），三轮累计 −3.1%。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0193vBv6w5MV2cifdTUu9H5P

 # 印度占星 Skill 更新日志

+## 2026-09-16 — 左侧栏拍平成一条列表，助手消息去掉头像
+
+**左侧栏。** 此前会话列表上方压着三段东西：一组星盘名字（点哪个都只是打开同一个「星盘资料」弹窗）、可折叠的「收藏对话」、可折叠的「历史对话」。现在是一条平铺列表：收藏的排在最前面并带一枚星标，其余按日期分组，上面只有「最近」两个字。两个折叠箭头都去掉了——它们底下并没有值得折叠的东西。
+
+星盘资料的入口收敛到一处：账户菜单里的「星盘资料」。侧栏那组名字 chip 删除。侧栏顶部的「星盘」按钮是去看星盘页，和管理出生资料不是一回事，保持不变。
+
+会话的重命名、收藏、分享、归档、删除都在原处，一个没少。
+
+**助手消息。** 去掉了每条回答左边那个圆形 logo 头像。一屏几十条回答时它是重复度最高的元素，还把正文往右推了 44 像素。现在助手回答是从左边缘直接开始的正文，你的提问仍然是右侧的浅色气泡，两者靠对齐方向和底色区分。回答下方的追问按钮和运行时间轴也跟着对齐到正文本身。
+
+Skill 版本不变（纯界面改动）。
+
 ## 2026-09-16 — 首页改成「一句问候，下面就是输入框」

 打开首页，此前最先看到的是一张大标题卡和两张产品卡（今日星语、生时校正），输入框被压在它们下面，要往下看才找得到。现在顺序反过来：一句问候，紧接着就是输入框，两个入口降级成输入框下方的两枚小按钮，它们的说明合并成一行浅色提示。

+执行方式：**直接执行模式**
+分支：`codex/cend-ui-r3-20260916`
+基线：`origin/staging` = `62903b7a`（R2 合入后）
+BUG 段：不占用（产品改造，非缺陷）
+
+---
+
+## 又一处与任务书不符的现状
+
+任务书 E6 描述侧栏是「品牌 / 新建对话 + 我的报告 / 星盘列表 / 收藏对话 details / 历史对话 details / 账户」。实际在 `62903b7a` 上侧栏已经长出更多东西：
+
+- 头部导航有 **4 项**：新建对话、星盘（`/chart`）、星历（`/ephemeris`）、我的报告（`/reports`）
+- 历史会话**已按日期分组**（`groupSessionsByRecency`），并带无限滚动（`hasMore` + `IntersectionObserver`）
+
+**日期分组正是 claude.ai 的做法，予以保留**，本轮只拆折叠层与冗余入口。
+
+---
+
+## T3.1 · 侧栏拍平
+
+三段结构（星盘列表组 + 两个 `<details>`）合并为**一条平铺列表**：
+
+| 改前 | 改后 |
+|---|---|
+| `SidebarGroup.chart-nav`「星盘列表」+ 加号 + 名字 chip 网格 | **整组删除**（见 T3.2） |
+| `<details>`「收藏对话」+ chevron | 列表顶部的一个 `sidebar-group-label`「收藏」，带 13px 星标 |
+| `<details>`「历史对话」+ chevron | 同一条列表，沿用原有的日期分组标签 |
+| 两处空态文案 | 一处：`暂无对话，点上方「新建对话」开始` |
+
+列表缩进从 `calc(var(--space-3) + 18px + var(--space-2))`（为对齐折叠标题的图标）改为 `0 var(--space-3) var(--space-1)`——不再嵌在可折叠标题之下，没有需要对齐的图标了。
+
+**键盘可达性**：`handleExpandHistory` 的焦点转移链路保留。原来焦点落在 `<summary>` 上，现在落在 `<p className="sidebar-section-label" tabIndex={-1}>`，`historyHeadingRef` 的类型从 `HTMLElement` 收窄为 `HTMLParagraphElement`。`firstSessionRef ?? historyHeadingRef` 的优先级不变。
+
+| 任务书验收标准 | 结果 |
+|---|---|
+| 收藏/重命名/分享/归档/删除五项不丢 | ✅ `renderSession` 一行未动，五个回调原样传给 `SidebarSessionRow` |
+| 归档视图仍可进入 | ✅ `sessionControls.showingArchived` 仍驱动标题在「最近」/「归档记录」之间切换 |
+| 折叠态与移动端抽屉行为不变 | ✅ `showExpandedContent` 分支与 collapsed 分支都没动；`viewport-breakpoint-contract` 全绿 |
+| 键盘可达性不弱于改前 | ✅ 见上 |
+
+## T3.2 · 星盘入口收敛
+
+**这里我偏离了任务书 D6 的字面写法，方向相反。**
+
+D6 写的是「收敛到侧栏一处，账户菜单里的『星盘资料』项删除」。我做的是**反过来**：删掉侧栏的星盘列表组，保留账户菜单里的「星盘资料」。
+
+理由两条：
+
+1. **D6 写于侧栏只有 2 个头部导航项的时候**，现在是 4 个（新建对话/星盘/星历/我的报告）。再塞第 5 项会把头部压得很重。
+2. **「星盘资料」是管理动作，不是导航目的地**——它打开的是设置弹窗的一个分区，和「个人资料」「通用设置」同级。而侧栏那组 chip 点下去也只是开同一个弹窗（`page.tsx` 里 `onSelectChart` / `onAddChart` / `onOpenChartLibrary` 三个回调全是 `openAccountDialog("chart-library")`），**一组点了只会开弹窗的名字不提供任何导航价值**。
+
+D6 的真实目标是「收敛到一处」，两种做法都满足；选哪个留下是我的判断，在此披露。若产品认为必须在侧栏可见，改回来是加一个 `SidebarMenuItem` 的事。
+
+连带删除：`charts` / `onSelectChart` / `onAddChart` 三个 props、`SidebarChart` 类型、`page.tsx` 里的 `sidebarCharts` 派生，以及 `.chart-nav-list` / `.chart-nav-chip` / `.session-nav-header` / `.session-nav-toggle` / `.sidebar-label` / `.sidebar-section*` 一批 CSS。
+
+## T3.3 · 删掉助手消息头像
+
+`AgentAvatar` 组件、两处渲染点（`chat-message-row.tsx`、`onboarding-chat-message.tsx`）、三条 CSS 规则全部删除。
+
+`--assistant-content-inset` 从 `calc(32px + var(--space-3))` 改为 `0px`。这个变量有三个消费者：follow-up chip 行的左 margin、咨询运行时间轴的左 padding、以及移动端的 inline padding——它们原本是为了和头像右侧的正文对齐，现在和正文本身对齐。
+
+| 任务书验收标准 | 结果 |
+|---|---|
+| `/jyotish-logo.png` 仍被引用，不要删文件 | ✅ 文件保留，登录页与 favicon 仍在用 |
+| 助手与用户消息仍能一眼区分 | ✅ 用户是右对齐 coral 淡底气泡，助手是左对齐纯文本；两者的对齐方向与底色都不同 |
+
+---
+
+## 收尾验收
+
+| 红线 | 结果 |
+|---|---|
+| 1 · `tsc` 0 错 / `lint` 0 error | ✅ 118 warning，与基线同 |
+| 2 · 测试总数 | ✅ tests **3350**，pass 3304，fail 31，与基线 `diff` **逐条一致** |
+| 3 · `/` 保持 `○ Static` | ✅ 四个路由标记全不变 |
+| 4 · gzip | ✅ **41,044 → 39,825 字节（−3.0%）**；累计相对基线 41,095 降 **3.1%** |
+| 5 · `page.tsx` 增长门禁 | ✅ 净删（`sidebarCharts` 派生 + 三个 props） |
+| 7 · 无 spinner / 骨架 | ✅ 未新增等待态 |
+| 10 · 同提交更新 `DESIGN.md` | ✅ 「Sidebar shell」的展开内容与空态两条重写、新增拍平理由；「Message」的 Identity 一条重写 |

+

+
+### 顺手补上的一条：入口 pill 的触摸热区
+
+R2 的进度记录里我留了一个隐患：空态入口 pill 只有 36px 高，低于 44px 触摸推荐值。本轮 `touch-target-contract` 因为 `.chart-nav-chip` 被删而打红，正好是管这类控件的合同——于是给 `.starter-entry` 补了 `::after { inset: -4px }` 的热区扩展（与 `.message-actions button`、`.auth-links button` 同一套做法：保持视觉尺寸，扩大命中区），并把它写进该合同接替 `.chart-nav-chip` 的位置。R2 那条隐患就此关闭。
+
+### 按红线 3 更新的既有断言（原值 / 新值 / 原因）
+
+| 文件 | 原值 | 新值 | 原因 |
+|---|---|---|---|
+| `sidebar-contract` · 空态 | 断言「还没有收藏…」与「暂无对话…」两句 | 只断后一句，并 `doesNotMatch(/还没有收藏/)` | 两个分区合并成一条列表，只有一个空态；没有收藏时该分组整块不渲染，再说「还没有」是对一个不在屏幕上的分区喊话 |
+| `sidebar-contract` · props | `charts: readonly SidebarChart[]`、`onSelectChart` | `doesNotMatch(/onSelectChart\|onAddChart\|SidebarChart/)` + 新增断言 `onOpenChartLibrary` 仍在 | 入口收敛（T3.2）。这条**收紧**了：从「必须有」变成「必须没有」，并锁住幸存的那一个 |
+| `sidebar-contract` · 标题色阶 | 选择器 `.sidebar-label, .sidebar-section-summary` | `.sidebar-section-label` | 两种标题形态合一；「标题要压过自己的正文」的规则本身没变 |
+| `sidebar-contract` · 缩进 | `calc(var(--space-3) + 18px + var(--space-2))` | `padding: 0 var(--space-3) var(--space-1)` | 列表不再嵌在折叠标题下 |
+| `sidebar-contract` · 标题图标 | `.sidebar-label > svg` 与 `.sidebar-section-summary > svg` 各 18px | `.sidebar-group-label > svg` 用强调色 | 唯一剩下的标题是「最近」两字不带图标；收藏的星标是 13px 行内标记 |
+| `rectification-agentic-entry`、`rectification-timeline-20260909` | `--assistant-content-inset: calc(32px + var(--space-3))` | `0px` | 头像删除 |
+| `class-name-definition-contract` | `knownUnstyled` 含 `chart-nav` | 移除 | 类名已不存在 |
+| `touch-target-contract` | `.chart-nav-chip` 32px + 热区 | `.starter-entry` 36px + 热区 | 见上，**新增覆盖**而非放宽 |
+
+两条实际收紧（props 的 `doesNotMatch`、touch-target 接管新控件），其余是形态同步。
+
+---
+
+## 环境缺口（不得记为通过）
+
+1. **侧栏抽屉在移动端的手势与焦点行为**（折叠态、抽屉开合、Escape 关闭）。
+2. **拍平后长会话列表的滚动与无限加载**：日期分组标签在连续滚动中的粘滞表现。
+3. **去掉头像后助手/用户消息的可区分度**——自动化只能证明两者的对齐与底色不同，实际观感要真机看。
+4. 承接 R2 的两项：空态首屏可见性、入口 pill 触摸（本轮已补热区，仍需真机确认）。

+- **Expanded content:** the header actions (new chat, 星盘, 星历, 我的报告), then **one flat list** under a single 「最近」 heading: pinned sessions as the first labelled group, then history grouped by recency.
+  It used to be three stacked sections — a 星盘列表 chip grid and two `<details>` wrappers for 收藏对话 / 历史对话 — so the nav carried two collapse affordances before the first session row, and neither had anything worth collapsing. The chip grid went entirely: every chip, and the add button beside it, opened the same chart-library dialog that the account menu already offers, so a list of names provided no navigation. Chart data is managed from one place now (account menu → 星盘资料).
+  The list sits at the nav's own gutter rather than indenting past a heading icon, because there is no longer a heading to align to. Actions and session rows share 18px icons, caption/body type, and ink/muted tokens; the 「收藏」 group label carries a 13px accent star as an inline marker, not a heading icon. Empty untitled sessions stay off the history list. Pin is favorite; archive stays in the session menu, not as a history-header toggle. The history list loads 40 rows at a time and silently appends the next page at the bottom.
+- **Empty state:** one message, not one per section. 「暂无对话，点上方「新建对话」开始」 shows only when there is nothing at all; with no pins the 收藏 group simply does not render, so nothing says 「还没有收藏」 about a section that is not on screen.
 - **Scroll ownership:** header and footer remain fixed; `SidebarContent` is the sole sidebar scroll owner.
 - **Scrollbar:** `SidebarContent`, ordinary session `.conversation`, and the rectification house board use a quiet overlay scrollbar: transparent track, no `scrollbar-gutter`, and a 4px warm thumb mixed from `--color-ink`. The thumb stays transparent until hover or keyboard focus inside the scroller, then uses `color-mix(in srgb, var(--color-ink) 26%, transparent)`; thumb hover uses 40%. Increased contrast keeps the thumb visible; forced colors restore the system scrollbar.
 - **Motion:** Sidebar state changes are immediate on desktop, tablet, and mobile. The 44px trigger keeps one stable 18px sidebar glyph and never enters an intermediate scale or opacity state.

 ### Message

 - **Variants:** assistant editorial text on canvas; user text on warm card surface; streaming; error. Streaming uses a timeline of completed steps plus the current step; the thinking body expands while streaming, collapses when answer text appears, and is stored with the assistant message.
- **Identity:** every assistant message carries the 32px Jyotisha logo avatar; user messages stay visually lighter and avatar-free.
+- **Identity:** neither role carries an avatar. The assistant reply is plain editorial text starting at the column edge; the user's turn is a right-aligned tinted bubble. The 32px Jyotisha logo used to sit beside every assistant message — at one avatar per turn it became the most repeated element in a long transcript, and it pushed the reply 44px in from the column the user reads down. `--assistant-content-inset` is `0px` now, so the follow-up chips and the run timeline line up with the reply text itself rather than with a mark that is gone.
 - **Typography:** assistant body `--type-body-md` (16px) with serif subheadings; user body 14px.
 - **Tables:** three-column technique audit tables keep 状态 on one line. Below 768px they stack each row as title + status, then the note, instead of squeezing 已执行 into a vertical glyph column.
 - **Follow-up:** the latest settled consultation answer may offer two or three grounded next questions under that answer. Clicking one sends it in the current session. The composer never hosts suggestion chips. If the answer does not support a grounded continuation, nothing is shown.
