+# 要件定义书直传入口 + 移除 rag-bar（含输入区上移根治）— 实施计划
+
+目标文件：`src/genesis/server/static/chat.html`、`frontend/src/main.ts`、`frontend/src/chat.css`
+后端零改动（沿用 `POST /api/sessions/{sid}/files`，`file_type=requirements`）。
+
+## 背景 / 问题
+- 点「上传资料」展开 `#upload-panel` → `#composer`（底部锚定）变高 → 顶部输入框/按钮被顶上去。
+- 需求：按钮改名「要件定义书」；**只允许上传要件定义书**；点击后**直接打开系统文件选择框**；选定即上传；其他资料改由项目配置提供。
+- 另有同类“上移”来源：`#rag-bar` 初始 `hidden`，**建会话后被显示** → 工具栏高度变化 → 输入区再跳一次。
+
+## 已确认决策
+- D1 选定文件后**自动上传**（选定即 POST，无二次确认）。
+- D2 未创建会话时点按钮 → 提示「请先发送一条消息以创建会话」。
+- D3 会话内**只传要件定义书**（`.xlsx`）；模板/规则/做成说明书由项目配置提供；`.xls` 不支持（后端 `EXPECTED_SUFFIX` 与 `excel_reader` 仅 `.xlsx`）。
+- D4 **移除 `#rag-bar`**（DOM + 相关前端 JS）。理由：影响调查已由聊天驱动（`chat/agent.py` 意图 `impact`，`tests/test_chat_intent.py` 覆盖），按钮冗余；RAG 现不可用（0 片段/禁用）。“启用 RAG/影响调查”待下一轮 RAG 落地再以合适方式加回。
+
+## 变更清单
+
+### chat.html
+- `#tb-upload`：`📎 上传资料` → `📄 要件定义书`；`title="上传要件定义书"`；补 `aria-label`。
+- 删除 `#upload-panel` 整块（`#file-type`、`.file-pick`、`#upload-btn`、`#proj-hint`）。
+- `#composer-toolbar` 内保留 `<input type="file" id="file-input" accept=".xlsx" style="display:none">` 与 `<span id="upload-status"></span>`。
+- **删除 `#rag-bar`**（`#rag-enabled` / `#rag-stats` / `#impact-btn`）。
+
+### frontend/src/main.ts
+- 删除常量 `fileTypeSel` / `projHintEl` / `uploadPanelEl`；保留 `fileInputEl` / `uploadStatusEl`。
+- 删除 `updateUploadBar()` 及**全部调用点**。
+- 删除 `UPLOAD_EXT_RULES` / `projectHasPrefixedType`；保留 `pickExt`。
+- 新增 `uploadRequirements()`：无 `sid` 提示 → 取文件 → 校验 `.xlsx` → `FormData(file_type=requirements)` POST → 刷新标题/侧边栏 → 聊天区提示；失败提示；**各路径均清空 `file-input.value`**。
+- 绑定：`#tb-upload` click → `fileInputEl.click()`；`fileInputEl` change → `uploadRequirements()`；删除 `#upload-btn` 绑定与面板切换。
+- **删除 RAG 相关前端代码**：常量 `ragEnabledEl` / `ragStatsEl` / `ragBarEl` / `impactBtnEl`；`RAG_LS_KEY` / `readRagFlag` / `writeRagFlag` / `refreshRagStats()` / `updateImpactButton()`；`ragEnabledEl` change 监听、`impactBtnEl` click 监听；以及 `refreshRagStats()` 的全部调用点。
+- `state.ts` 的 `resolveUploadType` / `shouldHideUploadSelect` 保留（node 测试覆盖），仅不再调用。
+
+### frontend/src/chat.css
+- 删除死样式：`#upload-bar`、`#upload-bar-inner`、`#upload-bar select(:focus)`、`.file-pick(:hover)`、`#upload-btn(:hover)`、`#proj-hint`、`#upload-panel`、`label.vh`。
+- **删除 RAG 样式**：`#rag-bar`、`#rag-bar label.rag-switch`、`#rag-bar input[type=checkbox]`(及 `:disabled`)、`#rag-bar .rag-stats(.ready/.zero)`、`#rag-bar button`(`:disabled`/`:hover:not(:disabled)`)。
+- 保留 `#upload-status`。
+
+## 验证
+- `cd frontend && npm run verify`（typecheck + node --test + build）。
+- `python -m pytest`（覆盖率 ≥99%）。
+- 手动：
+  - 点「要件定义书」→ 弹系统文件框（过滤 .xlsx）→ 选文件**自动上传** → 聊天区显示「上传完成」；
+  - **输入区/按钮不再上移**（上传面板已删、rag-bar 已移除、工具栏高度恒定）且仍钉底；
+  - 无会话时提示先发消息；聊天框输入「做影响调查」仍可触发后端影响调查意图。
+
+## 风险
+- 会话内不再能补传模板/规则/做成说明书 → 完全依赖项目配置；未配置则生成阶段报错（符合 D3）。
+- 移除 rag-bar 后，UI 不再有“启用 RAG / 影响调查”按钮；RAG 开关语义暂不可用（当前本就无效），下一轮 RAG 落地时重新引入。
+- 自动上传无二次确认（符合 D1）。
+
+---
+
+## 评审结论与计划调整（plan-eng-review）
+
+### 事实核对（Step 0）
+- 后端 `/files`：`file_type: str = Form(...)` + `file: UploadFile = File(...)`；`requirements` 允许，白名单 `(".xlsx",)`。✅
+- `updateUploadBar()` 定义 1 处 + 调用 5 处 + 上传分支内 1 处，删函数须清干净（漏调用 tsc 会报错）。✅
+- `.vh` 仅用于将被删的「上传类型」label。✅
+- 无测试引用将删的 id。✅
+
+### 采纳
+- **F1（同类“上移”来源）**：`#rag-bar` 建会话后出现会使工具栏变高 → 一并处理：**移除 rag-bar**（DOM+JS）。影响调查改由聊天驱动（已有意图解析）。
+- **F2**：仅 `.xlsx`（与后端/解析一致）；`accept` 仅过滤，`change` 再校验后缀。
+- **F3**：所有路径清空 `fileInputEl.value`（同文件再次可选）。
+- **F4**：清理上传相关死样式与 `.vh`。
+- **F7**：按钮补 `aria-label`。
+
+### 接受
+- **F5**：会话内不再补传模板/规则 → 依赖项目配置（D3 结果）。
+- **F6**：新上传流为 DOM 行为，无自动化测试；靠 tsc + 手动。
+
+## GSTACK REVIEW REPORT
+- STATUS: DONE
+- REVIEWED: docs/superpowers/plans/2026-09-12-requirements-upload.md
+- FINDINGS: F1 同类上移(已采纳:移除 rag-bar) / F2 扩展名(仅 .xlsx) / F3 重复选择(已纳入) / F4 死样式清理 / F7 aria；F5/F6 接受
+- KEY DECISION: 移除 rag-bar（影响调查由聊天驱动）；会话内仅传 .xlsx 要件定义书，选定即上传
+- NEXT: 待执行
