+# OA 或签 / 会签进度与 PDF 展示 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 审批详情「审批进度」与打印 PDF「审批流程」对或签/会签多人节点统一按纯文本行展示：`姓名 意见 时间`（未批「待处理」、或签免处理「无需处理」且仍列出）。
+
+**Architecture:** 抽纯函数 `formatProgressPersonLines`（及行态 `tone`）供 `OaProgressChain` 与 `buildFlowItems` 共用；PDF 模型增加 `personLines`，模板分行渲染。不改引擎收口语义，不改发起页预览。
+
+**Tech Stack:** Vue 3 · TypeScript · 现有 `OaProgressChain` / `oa-approval-print.ts` · `tsx` + `node:assert`（仓库无 vitest，用脚本测纯函数）
+
+**Spec:** `docs/superpowers/specs/2026-07-23-oa-or-and-sign-display-design.md`  
+**Demo:** `docs/mockups/oa-or-and-sign-progress-display-demo.html`

+## File map
+
+| Path | Responsibility |
+|------|----------------|
+| Create: `web-admin/src/utils/oa-progress-person-lines.ts` | 纯函数：`people[]` → 行文案 + tone |
+| Create: `web-admin/scripts/check-oa-progress-person-lines.ts` | 用 `tsx` 跑断言（无 vitest） |
+| Modify: `web-admin/src/components/oa-approval/OaProgressChain.vue` | 节点下渲染 person-lines；有行时隐藏节点级「意见：」避免双份 |
+| Modify: `web-admin/src/utils/oa-approval-print.ts` | `OaPrintFlowItem.personLines`；`buildFlowItems` 接入格式化 |
+| Modify: `web-admin/src/components/oa-approval/OaApprovalPrintSheet.vue` | 渲染 `personLines` 多行；弱化旧 `comment` 双份 |
+
+**Locked rules (from spec):**
+
+- 行格式：已处理 `{姓名} {意见或状态文案} {时间}`；未处理 `{姓名} 待处理`；或签免处理 `{姓名} 无需处理`（必须仍列出）。
+- `done` → 无需处理；`pending|running|not_reached` → 待处理。
+- 意见非空用原文；已处理意见空则用 `已同意`/`已拒绝`/`已打回` 等，禁止双空格。
+- 后端原则上不改；仅当前端缺字段时再补。

+
+### Task 1: 纯函数 + 断言脚本（TDD）
+
+**Files:**
+- Create: `web-admin/src/utils/oa-progress-person-lines.ts`
+- Create: `web-admin/scripts/check-oa-progress-person-lines.ts`

+- [ ] **Step 1: Write the failing check script first**
+
+Create `web-admin/scripts/check-oa-progress-person-lines.ts`:

+feat(web-admin): add OA progress person-line formatter for or/and sign
+
+Provide shared plain-text lines (name opinion time) used by progress UI and PDF.
+EOF
+)"
+```
+
+---
+
+### Task 2: 审批进度 UI（OaProgressChain）
+
+**Files:**
+- Modify: `web-admin/src/components/oa-approval/OaProgressChain.vue`
+
+- [ ] **Step 1: Import formatter and render person-lines**
+
+In `<script setup>` add:
+
+```ts
+import {
+  formatProgressPersonLines,
+  type ProgressPersonLine
+} from '@/utils/oa-progress-person-lines'
+
+function personLines(item: OaProgressChainItem): ProgressPersonLine[] {
+  if (item.kind === 'terminal' || item.kind === 'submit') return []
+  if (item.taskType === 'cc' || item.signMode === 'cc') return []
+  const list = displayPeople(item)
+  if (!list.length) return []
+  return formatProgressPersonLines(list)
+}
+
+function showNodeComment(item: OaProgressChainItem): boolean {
+  // 有按人行时不再展示节点级拼接意见，避免双份
+  if (personLines(item).length) return false
+  return Boolean(item.commentText)
+}
+```
+
+In template, **replace** the comment block and add lines after the card row (inside `.oa-flow-card`):
+
+```vue
+          <div v-if="personLines(item).length" class="oa-person-lines">
+            <p
+              v-for="(line, li) in personLines(item)"
+              :key="`${item.key}-pl-${li}`"
+              class="oa-person-line"
+              :class="{
+                'is-ok': line.tone === 'ok',
+                'is-pending': line.tone === 'pending',
+                'is-danger': line.tone === 'danger',
+                'is-mute': line.tone === 'mute'
+              }"
+            >
+              {{ line.text }}
+            </p>
+          </div>
+          <div v-else-if="showNodeComment(item)" class="oa-flow-card__comment">
+            意见：{{ item.commentText }}
+          </div>
+```
+
+Keep existing chips in the header row (高亮/灰显已由 `personChipClass` 覆盖 `done`→`is-mute`、`approved`→`is-ok`)。
+
+- [ ] **Step 2: Add scoped styles**
+
+```scss
+  .oa-person-lines {
+    margin-top: 8px;
+    display: grid;
+    gap: 4px;
+  }
+
+  .oa-person-line {
+    margin: 0;
+    color: var(--mint-text, #334155);
+    font-size: 12px;
+    line-height: 1.55;
+    word-break: break-word;
+
+    &.is-ok {
+      color: #059669;
+      font-weight: 500;
+    }
+
+    &.is-pending {
+      color: #d97706;
+    }
+
+    &.is-danger {
+      color: #dc2626;
+    }
+
+    &.is-mute {
+      color: #94a3b8;
+    }
+  }
+```
+
+- [ ] **Step 3: Smoke-check in browser**
+
+1. `cd web-admin && pnpm dev`
+2. 打开含或签多人节点的实例详情，确认：未批见「姓名 待处理」；一人同意后甲高亮行 + 乙丙「无需处理」灰显；节点下不再出现「意见：甲：…」拼接块。
+3. 会签部分完成：已批行含意见时间，未批「待处理」。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add web-admin/src/components/oa-approval/OaProgressChain.vue
+git commit -m "$(cat <<'EOF'
+feat(web-admin): show per-person approval lines on OA progress chain
+
+Render name/opinion/time under multi-approver nodes; hide duplicate node comment.
+EOF
+)"
+```
+
+---
+
+### Task 3: PDF buildFlowItems + PrintSheet
+
+**Files:**
+- Modify: `web-admin/src/utils/oa-approval-print.ts`
+- Modify: `web-admin/src/components/oa-approval/OaApprovalPrintSheet.vue`
+
+- [ ] **Step 1: Extend type and wire formatter in `buildFlowItems`**
+
+In `oa-approval-print.ts`:
+
+1. Import:
+
+```ts
+import { formatProgressPersonLines } from '@/utils/oa-progress-person-lines'
+```
+
+2. Change type:
+
+```ts
+export type OaPrintFlowItem = {
+  left: string
+  right: string
+  /** @deprecated 多人节点改用 personLines；单人/发起人可保留 */
+  comment?: string
+  /** 或签/会签按人纯文本行 */
+  personLines?: string[]
+}
+```
+
+3. Add helper near `peopleDisplayNames`:
+
+```ts
+function progressPersonLinesFromItem(p: any): string[] {
+  const people = Array.isArray(p?.people) ? p.people : []
+  if (!people.length) return []
+  return formatProgressPersonLines(people).map((x) => x.text)
+}
+```
+
+4. In the `kind === 'pending_node'` branch, after building names, prefer person lines:
+
+```ts
+    if (kind === 'pending_node') {
+      const personLines = progressPersonLinesFromItem(p)
+      const head = signLabel ? `【${title}·${signLabel}】` : `【${title}】`
+      items.push({
+        left: personLines.length
+          ? `${head} ${st}`
+          : name
+            ? `${head} ${name} ${st}`
+            : `${head} ${st}`,
+        right: personLines.length ? '' : ts,
+        personLines: personLines.length ? personLines : undefined
+      })
+      continue
+    }
+```
+
+5. Replace the task branch (comment `// task（或签/会签…）`) with:
+
+```ts
+    // task（或签/会签同节点多人已合并）
+    const head = signLabel ? `【${title}·${signLabel}】` : `【${title}】`
+    const personLines = progressPersonLinesFromItem(p)
+    if (personLines.length) {
+      items.push({
+        left: `${head} ${st}`,
+        right: '',
+        personLines
+      })
+      continue
+    }
+    items.push({
+      left: name ? `${head} ${name} ${st}` : `${head} ${st}`,
+      right: ts,
+      comment: comment || undefined
+    })
+```
+
+Keep submit / terminal / cc behavior unchanged（submit 仍可用单行 `comment`）。
+
+- [ ] **Step 2: Update PrintSheet template**
+
+In `OaApprovalPrintSheet.vue`, inside `.oa-print-flow__cell`, after the left/right row:
+
+```vue
+                  <div v-if="f.personLines?.length" class="oa-print-flow__person-lines">
+                    <div
+                      v-for="(line, li) in f.personLines"
+                      :key="li"
+                      class="oa-print-flow__person-line"
+                    >
+                      {{ line }}
+                    </div>
+                  </div>
+                  <div
+                    v-else-if="f.comment"
+                    class="oa-print-flow__comment"
+                  >
+                    意见：{{ f.comment }}
+                  </div>
+```
+
+Add styles:
+
+```scss
+.oa-print-flow__person-lines {
+  margin-top: 6px;
+  display: grid;
+  gap: 3px;
+}
+.oa-print-flow__person-line {
+  line-height: 1.55;
+  word-break: break-word;
+  white-space: pre-wrap;
+}
+```
+
+- [ ] **Step 3: Extend check script for buildFlowItems or签样例（可选但推荐）**
+
+Append to `web-admin/scripts/check-oa-progress-person-lines.ts` (or create second assert block in same file):
+
+```ts
+import { buildFlowItems } from '../src/utils/oa-approval-print'
+
+  const detail = {
+    progress: [
+      {
+        kind: 'submit',
+        title: '发起人',
+        status: 'submitted',
+        assigneeUserName: '张三',
+        timestamp: '2026-07-23 09:00:00',
+        people: []
+      },
+      {
+        kind: 'task',
+        title: '部门审批',
+        status: 'approved',
+        signMode: 'or',
+        timestamp: '2026-07-23 10:05:00',
+        commentText: '甲：同意，材料齐全',
+        people: [
+          {
+            nickName: '甲',
+            status: 'approved',
+            commentText: '同意，材料齐全',
+            timestamp: '2026-07-23 10:05:00'
+          },
+          { nickName: '乙', status: 'done' },
+          { nickName: '丙', status: 'done' }
+        ]
+      },
+      { kind: 'terminal', title: '流程结束', status: 'done', timestamp: '2026-07-23 10:05:00' }
+    ]
+  }
+  const flow = buildFlowItems(detail)
+  const taskFlow = flow.find((x) => x.left.includes('部门审批'))
+  assert.ok(taskFlow)
+  assert.ok(taskFlow!.left.includes('或签'))
+  assert.deepEqual(taskFlow!.personLines, [
+    '甲 同意，材料齐全 2026-07-23 10:05:00',
+    '乙 无需处理',
+    '丙 无需处理'
+  ])
+  assert.equal(taskFlow!.comment, undefined)
+```
+
+Note: `buildFlowItems` 当前文件有 Vue/`html2canvas` 副作用依赖；若 `tsx` 导入失败，可只保留 Task 1 纯函数断言，本步改为手动打印验收，**不要**为测 PDF 强行拆文件除非导入报错。
+
+若导入报错，跳过本脚本扩展，改为 Step 4 手工验收。
+
+- [ ] **Step 4: Manual PDF check**
+
+1. 在「我发起的」对或签已通过实例点「打印」，打开 PDF「审批流程」。
+2. 期望类似：
+
+```
+【部门审批·或签】 已同意
+甲 同意，材料齐全 2026-07-23 10:05:00
+乙 无需处理
+丙 无需处理
+```
+
+3. 会签完成实例：每人一行「姓名 意见 时间」，无表头三列。
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add web-admin/src/utils/oa-approval-print.ts \

+```
+
+---
+
+### Task 4: 回归与收尾
+
+**Files:** none required（可选：在 print PDF design 文首加一句「多人节点见 2026-07-23 spec」——仅当发现文档仍写「姓名逗号拼接」且易误导时再改）

+cd backend && source venv/bin/activate && pytest tests/test_oa_engine.py::TestProgressItems::test_or_sign_same_node_merged_into_one_card -v
+```
+
+（若类名路径不同，用：`pytest tests/test_oa_engine.py -k or_sign_same_node_merged -v`）
+
+Expected: PASS — `people` 仍含三人含 `done`。

+- [ ] **Step 3: Acceptance checklist (spec §7)**
+
+- [ ] 或签未批：进度 + PDF 见全部候选人（待处理）
+- [ ] 或签一人同意：仅操作人高亮；乙丙「无需处理」仍在
+- [ ] 会签部分/全部：每人一行意见时间
+- [ ] 无表头三列表格
+- [ ] 单人节点、抄送、终态无回归
+- [ ] 节点级「意见：甲：…」在多人时不再与 person-lines 双显
+
+- [ ] **Step 4: Final commit only if docs tweaked; else done**
+
+若修改了 `docs/superpowers/specs/2026-07-15-oa-approval-print-pdf-design.md` 交叉引用：
+
+```bash
+git add docs/superpowers/specs/2026-07-15-oa-approval-print-pdf-design.md
+git commit -m "docs(oa): point print flow multi-approver display to 2026-07-23 spec"
+```

+
+| Spec 要求 | Task |
+|-----------|------|
+| §3 统一行格式 | Task 1 |
+| §4.1 或签高亮 + 无需处理仍列出 | Task 1–2（tone/chip）+ Task 3 PDF |
+| §4.2 会签每人一行 | Task 1–3 |
+| §5.1 OaProgressChain | Task 2 |
+| §5.2 buildFlowItems + PrintSheet | Task 3 |
+| §5.3 隐藏节点级双份意见 | Task 2–3 |
+| §7 验收 | Task 4 |
+| 不改引擎 | 无后端改动任务 |
+
+**Placeholder scan:** 无 TBD；`tsx` 导入 `buildFlowItems` 失败时的降级路径已写明。
+
+**Type consistency:** `ProgressPersonLine.text/tone`；`OaPrintFlowItem.personLines: string[]`（PDF 不需要 tone，避免模板复杂化）。
