+# Event List Export 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:** Rename the existing event list export action to “事件导出”, add independent waveform export selection and download behavior, and show the visible event columns in the requested order with “暂降/暂升幅值(%)” before “持续时间(s)”.
+
+**Architecture:** Keep all UI orchestration in `frontend/src/views/event/eventList/index.vue`, because the change is narrow and the page already owns table columns, export handlers, and row actions. Add one event-list API method and one request type for waveform export. Extend the existing eventList contract scripts so selection semantics and export payloads are checked without introducing a new test framework.
+
+**Tech Stack:** Vue 3 `<script setup>`, Element Plus, TypeScript, existing `ProTable`, existing download hook, Node-based contract scripts.
+
+---
+
+## File Structure
+
+- Modify `frontend/src/views/event/eventList/check-search-layout-contract.mjs`: assert the event export button text and event export parameter source.
+- Modify `frontend/src/views/event/eventList/check-visible-contract.mjs`: assert the waveform selection column and selection rules.
+- Create `frontend/src/views/event/eventList/check-export-contract.mjs`: assert the new waveform export API, payload shape, button state, and cleanup behavior.
+- Modify `frontend/src/api/event/eventList/interface/index.ts`: add `TransientWaveformExportParams`.
+- Modify `frontend/src/api/event/eventList/index.ts`: add `exportTransientWaveforms`.
+- Modify `frontend/src/views/event/eventList/index.vue`: add independent waveform selection UI and handlers, rename event export, and wire waveform export.
+
+## Task 1: Contract Checks For Export Behavior
+
+**Files:**
+- Modify: `frontend/src/views/event/eventList/check-search-layout-contract.mjs`
+- Modify: `frontend/src/views/event/eventList/check-visible-contract.mjs`
+- Create: `frontend/src/views/event/eventList/check-export-contract.mjs`
+
+- [ ] **Step 1: Update search layout contract for event export naming**
+
+In `frontend/src/views/event/eventList/check-search-layout-contract.mjs`, keep the existing current-search assertion and add a check that the button is now labeled “事件导出”:
+
+```js
+[
+    'event export button is named explicitly',
+    /<el-button[\s\S]*@click="handleEventExport"[\s\S]*>事件导出<\/el-button>/
+],
+[
+    'event export uses the same current search params as the table request',
+    /exportTransientEvents,[\s\S]*buildEventQueryParams\(resolveCurrentSearchParams\(searchParam\)\)/
+]
+```
+
+- [ ] **Step 2: Update visible contract for waveform selection column**
+
+In `frontend/src/views/event/eventList/check-visible-contract.mjs`, add expectations that identify the manual waveform selection column and confirm the old business columns remain:
+
+```js
+[
+    'waveform selection column is rendered near the left side',
+    /prop:\s*'waveformSelection'[\s\S]*label:\s*'波形选择'[\s\S]*headerRender:\s*renderWaveformSelectionHeader[\s\S]*render:\s*renderWaveformSelectionCell/
+],
+[
+    'waveform selection requires event id, waveform flag and waveform path',
+    /const isWaveformExportable[\s\S]*Boolean\(row\.eventId\)[\s\S]*Number\(row\.fileFlag\)\s*===\s*1[\s\S]*Boolean\(row\.wavePath\)/
+]
+```
+
+- [ ] **Step 3: Create export contract script**
+
+Create `frontend/src/views/event/eventList/check-export-contract.mjs` with:
+
+```js
+/* eslint-env node */
+import fs from 'node:fs'
+import path from 'node:path'
+import { fileURLToPath } from 'node:url'
+
+const currentDir = path.dirname(fileURLToPath(import.meta.url))
+const pageFile = path.join(currentDir, 'index.vue')
+const apiFile = path.resolve(currentDir, '../../../api/event/eventList/index.ts')
+const interfaceFile = path.resolve(currentDir, '../../../api/event/eventList/interface/index.ts')
+const source = fs.readFileSync(pageFile, 'utf8')
+const apiSource = fs.readFileSync(apiFile, 'utf8')
+const interfaceSource = fs.readFileSync(interfaceFile, 'utf8')
+
+const expectations = [
+    ['waveform export api is imported by the page', /import \{[\s\S]*exportTransientWaveforms[\s\S]*\} from '@\/api\/event\/eventList'/],
+    ['waveform export button is present and disabled without selection', /<el-button[\s\S]*:disabled="!selectedWaveformRows\.length"[\s\S]*@click="handleWaveformExport"[\s\S]*>波形导出<\/el-button>/],
+    ['event export button does not depend on waveform selection', /<el-button type="primary" plain :icon="Download" @click="handleEventExport">事件导出<\/el-button>/],
+    ['waveform selected rows are tracked independently', /const selectedWaveformRows\s*=\s*ref<EventList\.TransientEventRecord\[\]>\(\[\]\)/],
+    ['waveform export payload uses event ids only', /eventIds:\s*exportableRows\.map\(row => row\.eventId\)/],
+    ['waveform export uses server filename download hook', /useDownloadWithServerFileName\(exportTransientWaveforms,\s*'事件波形导出'/],
+    ['waveform selection is cleaned after table reload triggers', /const clearWaveformSelection[\s\S]*selectedWaveformRows\.value\s*=\s*\[\]/],
+    ['waveform export api method exists', /export const exportTransientWaveforms\s*=\s*\(params:\s*EventList\.TransientWaveformExportParams\)/.test(apiSource)],
+    ['waveform export api path is stable', /downloadWithHeaders\('\/event\/list\/transient\/waveform\/export',\s*params\)/.test(apiSource)],
+    ['waveform export params type contains eventIds', /export interface TransientWaveformExportParams\s*\{[\s\S]*eventIds:\s*string\[\][\s\S]*\}/.test(interfaceSource)]
+]
+
+const failures = expectations.filter(([, pattern]) => {
+    if (typeof pattern === 'boolean') return !pattern
+    return !pattern.test(source)
+})
+
+if (failures.length) {
+    console.error('eventList export contract check failed:')
+    for (const [name] of failures) {
+        console.error(`- ${name}`)
+    }
+    process.exit(1)
+}
+
+console.log('eventList export contract check passed')
+```
+
+- [ ] **Step 4: Run contracts and verify red**
+
+Run:
+
+```powershell
+node frontend/src/views/event/eventList/check-search-layout-contract.mjs
+node frontend/src/views/event/eventList/check-visible-contract.mjs
+node frontend/src/views/event/eventList/check-export-contract.mjs
+```
+
+Expected:
+
+- Existing checks may pass or fail depending on current user edits.
+- `check-export-contract.mjs` must fail with missing waveform export API, button, selection state, and payload expectations.
+
+- [ ] **Step 5: Commit contract red state**
+
+Do not commit a failing red state unless the user explicitly asks for granular commits. Keep it as local verification before implementation.
+
+## Task 2: API Type And Export Method
+
+**Files:**
+- Modify: `frontend/src/api/event/eventList/interface/index.ts`
+- Modify: `frontend/src/api/event/eventList/index.ts`
+
+- [ ] **Step 1: Add waveform export request type**
+
+In `frontend/src/api/event/eventList/interface/index.ts`, add this interface inside `export namespace EventList` after `TransientPageParams`:
+
+```ts
+export interface TransientWaveformExportParams {
+    eventIds: string[]
+}
+```
+
+- [ ] **Step 2: Add waveform export API method**
+
+In `frontend/src/api/event/eventList/index.ts`, add:
+
+```ts
+export const exportTransientWaveforms = (params: EventList.TransientWaveformExportParams) => {
+    return http.downloadWithHeaders('/event/list/transient/waveform/export', params)
+}
+```
+
+- [ ] **Step 3: Run export contract and verify API checks improve**
+
+Run:
+
+```powershell
+node frontend/src/views/event/eventList/check-export-contract.mjs
+```
+
+Expected: still fails because page UI and handlers are not implemented, but API method and type failures disappear.
+
+## Task 3: Waveform Selection UI And State
+
+**Files:**
+- Modify: `frontend/src/views/event/eventList/index.vue`
+
+- [ ] **Step 1: Add imports**
+
+Change imports in `index.vue`:
+
+```ts
+import { ElButton, ElCheckbox, ElRadioButton, ElRadioGroup } from 'element-plus'
+import { Download, RefreshRight, View } from '@element-plus/icons-vue'
+import {
+    exportTransientEvents,
+    exportTransientWaveforms,
+    getTransientEventDetail,
+    getTransientEventPage
+} from '@/api/event/eventList'
+```
+
+- [ ] **Step 2: Add waveform selection state**
+
+Add near the existing page refs:
+
+```ts
+const selectedWaveformRows = ref<EventList.TransientEventRecord[]>([])
+```
+
+- [ ] **Step 3: Add exportable row helpers**
+
+Add before `columns`:
+
+```ts
+const isWaveformExportable = (row: EventList.TransientEventRecord) => {
+    return Boolean(row.eventId) && Number(row.fileFlag) === 1 && Boolean(row.wavePath)
+}
+
+const currentWaveformRows = computed(() => proTable.value?.tableData || [])
+const currentExportableWaveformRows = computed(() => currentWaveformRows.value.filter(isWaveformExportable))
+const selectedWaveformIds = computed(() => selectedWaveformRows.value.map(row => row.eventId))
+const selectedWaveformIdSet = computed(() => new Set(selectedWaveformIds.value))
+const isAllCurrentWaveformsSelected = computed(() => {
+    const rows = currentExportableWaveformRows.value
+    return rows.length > 0 && rows.every(row => selectedWaveformIdSet.value.has(row.eventId))
+})
+const isCurrentWaveformSelectionIndeterminate = computed(() => {
+    const rows = currentExportableWaveformRows.value
+    if (!rows.length) return false
+    const selectedCount = rows.filter(row => selectedWaveformIdSet.value.has(row.eventId)).length
+    return selectedCount > 0 && selectedCount < rows.length
+})
+```
+
+- [ ] **Step 4: Add selection mutators**
+
+Add after the helper computed values:
+
+```ts
+const clearWaveformSelection = () => {
+    selectedWaveformRows.value = []
+}
+
+const toggleWaveformRowSelection = (row: EventList.TransientEventRecord, checked: boolean) => {
+    if (!isWaveformExportable(row)) return
+
+    if (checked) {
+        if (!selectedWaveformIdSet.value.has(row.eventId)) {
+            selectedWaveformRows.value = [...selectedWaveformRows.value, row]
+        }
+        return
+    }
+
+    selectedWaveformRows.value = selectedWaveformRows.value.filter(item => item.eventId !== row.eventId)
+}
+
+const toggleCurrentWaveformSelection = (checked: boolean) => {
+    if (!checked) {
+        const currentIds = new Set(currentExportableWaveformRows.value.map(row => row.eventId))
+        selectedWaveformRows.value = selectedWaveformRows.value.filter(row => !currentIds.has(row.eventId))
+        return
+    }
+
+    const nextRows = [...selectedWaveformRows.value]
+    const nextIds = new Set(nextRows.map(row => row.eventId))
+    currentExportableWaveformRows.value.forEach(row => {
+        if (!nextIds.has(row.eventId)) {
+            nextRows.push(row)
+            nextIds.add(row.eventId)
+        }
+    })
+    selectedWaveformRows.value = nextRows
+}
+```
+
+- [ ] **Step 5: Add render functions for the manual selection column**
+
+Add:
+
+```ts
+const renderWaveformSelectionHeader = () =>
+    h(ElCheckbox, {
+        modelValue: isAllCurrentWaveformsSelected.value,
+        indeterminate: isCurrentWaveformSelectionIndeterminate.value,
+        disabled: currentExportableWaveformRows.value.length === 0,
+        'onUpdate:modelValue': (value: string | number | boolean) => toggleCurrentWaveformSelection(Boolean(value))
+    })
+
+const renderWaveformSelectionCell = ({ row }: { row: EventList.TransientEventRecord }) =>
+    h(ElCheckbox, {
+        modelValue: selectedWaveformIdSet.value.has(row.eventId),
+        disabled: !isWaveformExportable(row),
+        'onUpdate:modelValue': (value: string | number | boolean) => toggleWaveformRowSelection(row, Boolean(value))
+    })
+```
+
+- [ ] **Step 6: Add waveform selection column**
+
+In the `columns` array, add this before the index column:
+
+```ts
+{
+    prop: 'waveformSelection',
+    label: '波形选择',
+    fixed: 'left',
+    width: 90,
+    isSetting: false,
+    headerRender: renderWaveformSelectionHeader,
+    render: renderWaveformSelectionCell
+},
+```
+
+- [ ] **Step 7: Place amplitude before duration in visible columns**
+
+In the `columns` array, keep the visible event column order as `发生时刻`, `监测点名称`, `暂降/暂升幅值(%)`, `持续时间(s)`, `事件类型`, `相别` by placing the `featureAmplitude` column before the duration column.
+
+- [ ] **Step 8: Clear waveform selection on reset and table request**
+
+Update `handleSearchReset`:
+
+```ts
+const handleSearchReset = () => {
+    eventTimeUnit.value = 'month'
+    eventTimeBaseDate.value = new Date()
+    clearWaveformSelection()
+    syncEventTimeRange()
+}
+```
+
+Update `getTableList`:
+
+```ts
+const getTableList = (params: EventSearchParams) => {
+    // 分页查询按 API_DEBUG.md 转换时间范围与枚举筛选参数。
+    clearWaveformSelection()
+    return getTransientEventPage(buildEventQueryParams(resolveCurrentSearchParams(params)))
+}
+```
+
+- [ ] **Step 9: Run visible and export contracts**
+
+Run:
+
+```powershell
+node frontend/src/views/event/eventList/check-visible-contract.mjs
+node frontend/src/views/event/eventList/check-export-contract.mjs
+```
+
+Expected: visible contract passes for the new column; export contract still fails until buttons and export handlers are renamed/wired.
+
+## Task 4: Export Buttons And Handlers
+
+**Files:**
+- Modify: `frontend/src/views/event/eventList/index.vue`
+
+- [ ] **Step 1: Replace table header buttons**
+
+Replace the existing table header slot with:
+
+```vue
+<template #tableHeader>
+    <el-button type="primary" plain :icon="Download" @click="handleEventExport">事件导出</el-button>
+    <el-button
+        type="primary"
+        plain
+        :icon="Download"
+        :disabled="!selectedWaveformRows.length"
+        @click="handleWaveformExport"
+    >
+        波形导出
+    </el-button>
+</template>
+```
+
+- [ ] **Step 2: Rename event export handler**
+
+Replace `handleExport` with:
+
+```ts
+const handleEventExport = () => {
+    const searchParam = (proTable.value?.searchParam || {}) as EventSearchParams
+    useDownloadWithServerFileName(
+        exportTransientEvents,
+        '暂态事件列表',
+        buildEventQueryParams(resolveCurrentSearchParams(searchParam)),
+        false
+    )
+}
+```
+
+- [ ] **Step 3: Add waveform export handler**
+
+Add after `handleEventExport`:
+
+```ts
+const handleWaveformExport = () => {
+    const exportableRows = selectedWaveformRows.value.filter(isWaveformExportable)
+
+    if (!exportableRows.length) {
+        ElMessage.warning('请先选择存在波形的事件')
+        return
+    }
+
+    useDownloadWithServerFileName(
+        exportTransientWaveforms,
+        '事件波形导出',
+        {
+            eventIds: exportableRows.map(row => row.eventId)
+        },
+        false,
+        '.zip'
+    )
+}
+```
+
+- [ ] **Step 4: Run all eventList contract scripts**
+
+Run:
+
+```powershell
+node frontend/src/views/event/eventList/check-search-layout-contract.mjs
+node frontend/src/views/event/eventList/check-visible-contract.mjs
+node frontend/src/views/event/eventList/check-export-contract.mjs
+node frontend/src/views/event/eventList/check-query-params-contract.mjs
+node frontend/src/views/event/eventList/check-route-contract.mjs
+node frontend/src/views/event/eventList/check-time-range-contract.mjs
+```
+
+Expected: all scripts print `passed`.
+
+## Task 5: Type And Lint Verification
+
+**Files:**
+- Verify only; no planned file edits.
+
+- [ ] **Step 1: Run TypeScript check**
+
+Run:
+
+```powershell
+cd frontend
+npm run type-check
+```
+
+Expected: command completes without TypeScript errors.
+
+- [ ] **Step 2: Run lint if lightweight enough for the workspace**
+
+Run:
+
+```powershell
+cd frontend
+npm run lint
+```
+
+Expected: command completes without ESLint errors. If lint changes unrelated files because it uses `--fix`, inspect `git status --short` and keep only changes directly related to this task.
+
+- [ ] **Step 3: Inspect final diff**
+
+Run:
+
+```powershell
+git diff -- frontend/src/views/event/eventList frontend/src/api/event/eventList
+git status --short
+```
+
+Expected:
+
+- Event list page contains the new independent waveform selection column.
+- API files contain only the waveform export type and method.
+- Existing unrelated worktree changes are not reverted or folded into this task.
+
+## Task 6: Commit Implementation
+
+**Files:**
+- Commit only files modified for this task.
+
+- [ ] **Step 1: Stage task files only**
+
+Run:
+
+```powershell
+git add -- frontend/src/views/event/eventList/index.vue frontend/src/views/event/eventList/check-search-layout-contract.mjs frontend/src/views/event/eventList/check-visible-contract.mjs frontend/src/views/event/eventList/check-export-contract.mjs frontend/src/api/event/eventList/index.ts frontend/src/api/event/eventList/interface/index.ts docs/superpowers/plans/2026-05-15-event-list-export-implementation-plan.md
+```
+
+- [ ] **Step 2: Commit**
+
+Run:
+
+```powershell
+git commit -m "feat: add event waveform export selection"
+```
+
+Expected: commit succeeds and includes only the implementation, contracts, API method, and this plan.
