 - **输入验证边界**：Zod schema 是否覆盖所有 IPC / 服务入口
 - **类型安全**：禁 `any`、禁不必要的 `as`、严守 `strict`
 - **事务**：多表写入（收件 / 取件 / 备份元数据更新）必须事务
 - **金额精度**：整型分、零浮点、汇总与明细一致性

 ### M1（基础）
+
 - Electron 安全：`contextIsolation` / `sandbox` / `nodeIntegration` / CSP / preload 暴露面最小
 - DB 初始化 & migration 的幂等性
 - 取件码 / 订单号生成的并发安全（单实例进程内也要事务重试）
 - 备份 → zip → rotate 链路的原子性与失败回滚

 ### M2（收款 & 统计）
+
 - 金额浮点陷阱（展示时再除 100）
 - 聚合查询性能（大表上的 `GROUP BY receive_date`）
 - Excel 导入的数据清洗与主键冲突处理

 ### M3（照片 & 打印）
+
 - 大文件（照片）的磁盘占用与清理策略
 - 打印驱动抽象是否真能支持换型号
 - 打印失败是否阻塞业务流程（必须异步 / 可重试）

 ### M4（员工 & SMS）

 - Argon2 参数（memory / time / parallelism）对 Windows 柜台 CPU 的影响
 - 会话机制（login 后怎么保持？Electron 单用户场景）

+# M1 Delivery 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:** Deliver `laundry-desk` M1 as a working Electron Windows NSIS app with receive, pickup, order list/detail, customer de-duplication, automatic/manual backup, type/lint/test gates, and CI artifact generation.
+
+**Architecture:** Keep the approved Electron split: main owns SQLite and services, preload exposes a narrow typed API, renderer uses IPC only. Replace the current prototype DB/bootstrap with focused service modules, explicit Zod IPC schemas, Drizzle relations, and deterministic tests using in-memory SQLite. M2-M4 placeholders are removed or hidden unless needed by M1.
+
+**Tech Stack:** Electron 41, React 19, TypeScript strict, Vite/electron-vite, better-sqlite3, Drizzle ORM, Zod, Vitest, Tailwind CSS, Playwright, electron-builder NSIS.
+
+**Status 2026-04-23:** M1 local delivery completed by Codex. Windows x64 NSIS artifact generated at `dist/laundry-desk Setup 0.1.0.exe`; SHA256 stored next to it. Final gates passed: `npm run lint`, `npm run typecheck`, `npm test -- --run`, `npm run test:e2e`, `npm run build:win`, and `npm audit --omit=dev --audit-level=high` with no high-severity production findings. Remaining audit item is moderate `uuid` via `exceljs` / Tencent Cloud SDK; npm's automatic fix is breaking, so it is intentionally not applied for M1.
+
+---
+
+### Task 1: Build And Tooling Baseline
+
+**Files:**
+
+- Modify: `package.json`
+- Modify: `tsconfig.node.json`
+- Modify: `tsconfig.web.json`
+- Modify: `electron.vite.config.ts`
+- Create: `eslint.config.js`
+- Modify: `vitest.config.ts`
+
+- [ ] **Step 1: Run current failing gates**
+
+Run: `npm run typecheck`, `npm run lint`, `npm test -- --run`
+Expected: failures document the current baseline.
+
+- [ ] **Step 2: Fix TypeScript project boundaries**
+
+Set `rootDir` to `src` or use `rootDirs` so `src/shared` compiles for node and web. Keep `strict` inherited from electron-toolkit.
+
+- [ ] **Step 3: Add working ESLint flat config**
+
+Use TypeScript parser/config compatible with ESLint 8 and React JSX. Make the lint script run without "config not found".
+
+- [ ] **Step 4: Rebuild native dependencies for local Node if needed**
+
+Run: `npm rebuild better-sqlite3`.
+Expected: Vitest can import `better-sqlite3`.
+
+- [ ] **Step 5: Re-run gates**
+
+Run: `npm run typecheck`, `npm run lint`, `npm test -- --run`
+Expected: tooling errors are resolved or narrowed to real implementation failures.
+
+### Task 2: Database And Service Core
+
+**Files:**
+
+- Modify: `src/main/db/schema.ts`
+- Modify: `src/main/db/index.ts`
+- Create: `src/main/db/migrate.ts`
+- Create: `src/main/db/client.ts`
+- Modify: `src/main/services/customerService.ts`
+- Modify: `src/main/services/orderService.ts`
+- Modify: `src/main/services/pickupCodeService.ts`
+- Modify: `src/main/services/auditService.ts`
+- Modify: `tests/unit/services.test.ts`
+
+- [ ] **Step 1: Write service tests for M1 behavior**
+
+Cover customer upsert by phone, order creation transaction, integer cents validation, order number sequencing, pickup code format, pickup search by code/phone/order number, pickup balance settlement, and audit log creation.
+
+- [ ] **Step 2: Verify tests fail for missing/incorrect behavior**
+
+Run: `npm test -- --run tests/unit/services.test.ts`
+Expected: failures for missing search, transaction/audit, validation, or schema gaps.
+
+- [ ] **Step 3: Implement DB initialization**
+
+Expose a `createDbClient(sqlite)` helper for tests and `getDb()` for app runtime. Enable WAL and foreign keys. Run idempotent SQL migrations for all M1 tables and indexes from one source.
+
+- [ ] **Step 4: Implement service behavior**
+
+Use transactions for create order and pickup. Generate `order_no` and `pickup_code` inside the transaction with unique-conflict retry. Recompute totals from item rows, require integer cents, require `paidAmount <= totalAmount`, and write audit rows through the same transaction.
+
+- [ ] **Step 5: Re-run unit tests**
+
+Run: `npm test -- --run tests/unit/services.test.ts`
+Expected: service tests pass.
+
+### Task 3: IPC Contract And Preload API
+
+**Files:**
+
+- Modify: `src/shared/index.ts`
+- Modify: `src/shared/schemas.ts`
+- Modify: `src/preload/index.ts`
+- Modify: `src/main/ipc/orders.ts`
+- Modify: `src/main/ipc/customers.ts`
+- Modify: `src/main/ipc/settings.ts`
+- Create: `src/main/ipc/backup.ts`
+- Modify: `src/main/index.ts`
+
+- [ ] **Step 1: Write IPC schema tests where practical**
+
+Cover invalid order id, invalid search query, invalid settings key, and invalid backup action schemas.
+
+- [ ] **Step 2: Implement uniform IPC helpers**
+
+Every handler returns `{ ok: true, data } | { ok: false, error }`, logs detailed errors in main, and returns user-safe messages.
+
+- [ ] **Step 3: Narrow preload exposure**
+
+Expose only `window.api`; remove default `window.electron`; use typed request/response signatures instead of `any`.
+
+- [ ] **Step 4: Add CSP and production-safe window behavior**
+
+Remove debug background, `alwaysOnTop`, devtools auto-open, and fixed startup delay. Add CSP to renderer HTML.
+
+- [ ] **Step 5: Re-run typecheck/lint**
+
+Run: `npm run typecheck && npm run lint`
+Expected: zero errors.
+
+### Task 4: Renderer M1 Flows
+
+**Files:**
+
+- Modify: `src/renderer/index.html`
+- Modify: `src/renderer/src/assets/main.css`
+- Modify: `src/renderer/src/env.d.ts`
+- Modify: `src/renderer/src/routes/index.tsx`
+- Modify: `src/renderer/src/components/Layout.tsx`
+- Modify: `src/renderer/src/routes/Home.tsx`
+- Modify: `src/renderer/src/routes/Receive.tsx`
+- Modify: `src/renderer/src/routes/Pickup.tsx`
+- Modify: `src/renderer/src/routes/Orders.tsx`
+- Modify: `src/renderer/src/routes/OrderDetail.tsx`
+- Modify: `src/renderer/src/routes/Customers.tsx`
+- Modify: `src/renderer/src/routes/Settings.tsx`
+
+- [ ] **Step 1: Add focused renderer tests if test harness exists, otherwise rely on typecheck and manual/E2E smoke**
+
+Validate route imports compile and typed IPC calls are correct.
+
+- [ ] **Step 2: Restore usable styling**
+
+Either configure Tailwind correctly or replace with a compact CSS utility layer sufficient for the current class usage. Preserve Apple HIG-inspired layout and responsive behavior.
+
+- [ ] **Step 3: Complete receive flow**
+
+Phone lookup, customer upsert, item rows with cents conversion, partial payment selection, validation messages, success reset, and navigation to order detail.
+
+- [ ] **Step 4: Complete pickup flow**
+
+Search by pickup code, phone, order number, or customer name; render results; support balance settlement and picked-up transition.
+
+- [ ] **Step 5: Complete list/detail/settings M1 routes**
+
+Order list pagination basics, order detail with print button hidden/disabled until M3, customers list/search, settings shop name, manual backup, and backup list/restore placeholder only if clearly marked out-of-scope.
+
+### Task 5: Backup And Delivery Verification
+
+**Files:**
+
+- Modify: `src/main/services/backupService.ts`
+- Modify: `src/main/ipc/backup.ts`
+- Modify: `tests/unit/services.test.ts`
+- Modify: `.github/workflows/build.yml`
+- Modify: `README.md`
+- Create: `docs/CHANGELOG.md`
+
+- [ ] **Step 1: Add backup tests**
+
+Use a temp directory and a test database. Verify backup zip is created atomically, contains `laundry.db`, and rotate keeps 30 newest files.
+
+- [ ] **Step 2: Implement backup service**
+
+Checkpoint WAL, write to temp zip, finalize, rename atomically, rotate after success, and expose manual backup IPC.
+
+- [ ] **Step 3: Add CI gates**
+
+Run install, typecheck, lint, test, build, and `build:win`. Upload NSIS artifact and SHA256.
+
+- [ ] **Step 4: Run local verification**
+
+Run: `npm run typecheck`, `npm run lint`, `npm test -- --run`, `npm run build`
+Expected: all pass locally.
+
+- [ ] **Step 5: Attempt package verification**
+
+On macOS run `npm run build:unpack` if supported. Final `.exe` must be generated by GitHub Actions `windows-latest`.

 ## 6. 核心工作流

 ### 6.1 收件
+
 电话查回头客 → 明细多行 → 付款方式 + 实收 → 事务生成 `pickup_code` + `order_no` → 写 `orders` + `order_items`（+ 可选 `order_photos`）→ 更新 `customers.total_orders/total_spent` → `audit_log` → （M3）打印登记单。

 ### 6.2 取件
+
 取件码（优先）/ 电话 / 单号 / 姓名查询 → 多条时列表选 → 有欠款先收 → `status = picked_up`、`actual_pickup_at`、`picked_up_by` → `audit_log` → （M3）打印取件条。

 ### 6.3 自动备份
+
 `app.ready` 启动 `node-cron` 03:00 → `PRAGMA wal_checkpoint(TRUNCATE)` → 复制 `.db` → zip → 滚动保留 30 份。

 ### 6.4 短信通知（M4）
+
 手动/批量触发 → Service 调腾讯云 SMS SDK → 写 `sms_log`（pending → sent/failed）→ 状态回填订单详情。
