+当前已完成 **A0 工程骨架与契约基线**（monorepo、API/Worker/Web 骨架、Prisma 平台表、shared 契约包、UI 包、布局与登录壳、CI 与冒烟测试）；业务模块从 A1 起按开发计划推进。目录与依赖方向见 [AGENTS.md §5](AGENTS.md)。

-## 本地开发（建仓后适用）
+## 本地开发
+
+前置：Node.js `24.15.0`（`.nvmrc`）、pnpm `10.x`、Docker。
 
 ```bash
 cp .env.example .env.local
-pnpm compose:up          # PostgreSQL 18 / Redis 7.4 / MinIO
+cp .env.local .env          # Prisma CLI 只读取 .env（两者均已 gitignore）
-pnpm db:migrate
+pnpm check:dev              # 检查本机 PostgreSQL / Redis 是否可用
-pnpm dev
+pnpm db:init                # 首次/迁移后：应用已有迁移 + 幂等种子（不重置数据、不改已有密码）
+pnpm dev                    # 并行启动 api(3000) / web(5173) / worker
 ```
 
-命令与门禁见 [AGENTS.md §6](AGENTS.md) 与 [06-测试与CI规范](docs/工程规范/06-测试与CI规范.md)。
+> **日常启动不需要执行任何数据库命令**。`pnpm dev` / `./dev.sh` 都不会迁移、播种或重置数据库，已有账号密码保持不变。
+> **只有需要清空本地库时才用 `pnpm db:reset`**：它会清空全部表并重新 seed，admin 等种子账号会回到初始密码 `lingxi2026` 且 `must_change_password=true`。为避免误清本地改过的密码/数据，该命令默认被拦截，必须显式执行：
+>
+> ```bash
+> ALLOW_DB_RESET=1 pnpm db:reset   # 确认清库才执行
+> ```
+>
+> 日常迁移 / 补种子请用 `pnpm db:init`（幂等，不改已有密码）。
+> 生产环境部署只用 `prisma migrate deploy`（`db:init` 的第一步），**不执行 seed / reset**；用户密码不会因重启或发布被重置。
+
+也可以使用一键脚本（自动检测并释放端口、带健康检查，启动后默认跟随日志）：
+
+```bash
+./dev.sh                    # 启动 api + web + worker，并前台跟随日志（Ctrl+C 停止全部）
+./dev.sh start -d           # 后台启动
+./dev.sh status             # 端口 / PID / 健康状态
+./dev.sh logs [api|web|worker]  # 跟踪日志（默认全部）
+./dev.sh stop               # 停止并释放 3000 / 5173
+./dev.sh --help             # 全部参数
+```
+
+> `dev.sh` 只负责开发服务，不启动 PostgreSQL / Redis 或任何 Docker 容器；这两者按约定在开发前已就绪。
+
+- **本地数据库**：直接复用本机已有 Docker 服务 `docker-postgres-1`（PostgreSQL 18，`127.0.0.1:5432`），库名 `lingxi`，用户 `postgres`，密码 `postgres`；Redis 复用 `docker-redis-1`（`127.0.0.1:6379`）。请先确认这两个容器已启动，本仓库不会另起 PG/Redis。
+- **对象存储**：使用公网 RustFS（`https://oss.xinsenidea.com`，桶 `lingxi-dev`）；A0 的 `assets / renders / temp` 三类产物暂共用该桶，待 A1 按前缀拆分。真实 access key / secret 只写入本地 `.env.local`（已 gitignore），仓库内只保留占位。
+- **API 文档**：启动 api 后访问 `http://127.0.0.1:3000/api/docs`，OpenAPI JSON 在 `openapi/lingxi.openapi.json`。
+- **演示登录**：A0 尚未接鉴权（A1 实现），`VITE_PUBLIC_DEMO_SESSION=true` 时登录页使用本地演示会话进入工作台；A1 接入真实登录后删除。
+
+常用校验：
+
+```bash
+pnpm lint && pnpm typecheck && pnpm test   # 本地门禁
+VITE_PUBLIC_DEMO_SESSION=true pnpm test:e2e  # 构建 + 端到端冒烟（demo 会话）
+pnpm openapi:export && pnpm openapi:diff   # 契约快照与破坏性变更检查
+pnpm ci:local                              # 本地跑完整 CI 门禁（已内置 e2e 所需 env）
+```
+
+> **远端 Gitea 未部署 Actions runner，线上 CI 不可用**。所有 CI 一律在本地执行：推送前跑 `pnpm ci:local`（或至少 `format:check + lint + typecheck + test`）。`.gitea/workflows/ci.yml` 仅作本地流水线参考 / 手动触发，**不随 push 自动运行**。
+
+命令与门禁见 [AGENTS.md §6](AGENTS.md) 与 [06-测试与CI规范](docs/工程规范/06-测试与CI规范.md)。当前 UI 采用「顶部模块菜单 + 左侧功能菜单」布局，视觉方向为 **A · 云白蓝（传统企业后台 + 现代浅色质感）**。
