+
+业务错误、具名鉴权、多行文档及下述开发命令从 CLI `v0.7.0-preview.1` 提供。
+
+## 业务错误：声明、代码和文档共用一份定义
+
+```go
+error (
+    Unauthenticated 401 "UNAUTHENTICATED" "authentication required"
+    Forbidden 403 "FORBIDDEN" "permission denied"
+    UserNotFound 404 "USER_NOT_FOUND" "user not found"
+    EmailTaken 409 "EMAIL_TAKEN" "email already in use"
+)
+```
+
+也可写单条 `error EmailTaken 409 "EMAIL_TAKEN" "email already in use"`，或把错误目录放进相对导入的 `errors.api`。
+名称用 UpperCamelCase，HTTP 状态范围 400–599，错误码用大写字母/数字/下划线且全局唯一，message 是可公开返回的稳定提示。
+
+`@server (errors: Unauthenticated)` 声明组级错误；路由 `@errors UserNotFound, EmailTaken` 追加到组级列表并去重。
+`@errors none` 清空继承的业务错误。未声明、重复声明或生成符号冲突会报告源码位置。
+
+生成 `internal/apierrors/errorsGen.go`：
+
+```go
+return nil, apierrors.EmailTaken()
+// 可用 apierrors.CodeEmailTaken 引用同一个错误码。
+```
+
+每次调用返回新错误，避免并发修改共享错误对象。生成器不会自动把任意数据库错误转成业务错误；由 Service/适配层调用这些函数。
+内部 Cause 可能进入访问日志，敏感驱动报错应像 userService 示例一样先归类再转换。
+
+OpenAPI 对每个状态生成标准响应结构和命名 examples，同一 409 下多个错误不会相互覆盖；纯业务状态还列出 code enum。
+默认框架错误状态与自动添加的鉴权 401 保留开放的 code 字段，容纳校验器/中间件实际错误。
+`x-omni-errors` 提供错误目录与路由关联。文档声明不拦截、改写或穷举运行时的所有错误。
+
+## 鉴权：声明与路由注册一起变化
+
+```go
+auth UserAuth (
+    type: bearer
+    middleware: Auth
+    description: "Application access token"
+)
+
+@server (
+    group: user
+    prefix: /api/v1
+    auth: UserAuth
+    errors: Unauthenticated
+)
+service user-api {
+    @errors Forbidden, EmailTaken
+    @handler createUser
+    @status 201
+    post /users (CreateUserReq) returns (UserResp)
+
+    @auth none
+    @errors none
+    @handler publicStatus
+    get /status
+}
+```
+
+`auth` 是具名契约，`middleware` 指向实际 hook；生成器把它放在普通 middleware 前面执行，并在注册任何路由前检查 hook 非空。
+新 hook 未实现时返回 501，已有手写 hook 保留。需要在 hook 中验证凭证、失效时间、签发者、权限等；声明不会自动实现登录或 JWT 校验。
+
+- `type: bearer`：对应 HTTP Bearer，可选 `bearerFormat: JWT`，这只是文档提示。
+- `type: apiKey`：必须同时声明 `in: header` 或 `in: cookie` 和 `name`，例如 `X-API-Key` 或 `sessionId`。
+- `auth: UserAuth` 可在组级使用；路由 `@auth OtherAuth` 替换，`@auth none` 撤销继承的声明鉴权。普通 middleware 继续保留。
+- 不要再把该 auth 的 hook 重复写进普通 middleware。不支持 query token、多个方案 AND/OR、OAuth2 scopes 或隐含认证策略。
+- 被保护路由自动描述 401；403 和具体错误码由 `@errors` 明确声明。未声明 auth 的旧项目仍按其原有 middleware 执行。
+
+文档生成 `components.securitySchemes` 与逐接口 `security`；显式公共接口使用空数组。
+结构遵循 [OpenAPI 3.0.3 Security Requirement](https://spec.openapis.org/oas/v3.0.3.html#security-requirement-object)。
+
+## 文档和日常开发命令
+
+保留单行 `@doc "摘要"`，也可以：
+
+```go
+@doc (
+    summary: "Create a user"
+    description: "Writes user data and audit in the same transaction"
+    tags: users, administration
+    deprecated: false
+)
+```
+
+未设置 tags 时使用 group 分组。`info` 的 description/desc 也会进入 OpenAPI；两者不能同时声明。
+
+在生成项目目录内，不必重复输入 API 路径：
+
+```sh
+go-omni api validate              # 发现 manifest 中的入口并校验
+go-omni api inspect               # 方法、路径、Handler、鉴权与业务错误总览
+go-omni api generate --dry-run    # 预览新增/更新/移除，完全不写文件
+go-omni api generate              # 实际生成，保留手写业务
+go-omni api generate --check      # 只读检查，可用于 CI
+go-omni api export > openapi.json # 独立导出纯 JSON，无需启动服务
+go test ./...
+```
+
+`--dry-run` 和 `--check` 不能组合。新项目预览也不创建目录；预览不是审批或锁定，实际生成会重新检查文件状态。
+在项目外可显式传 `--api`；生成时传 `--dir` 可定位其他项目。不会猜测多个 .api 中哪个是入口。
+路由总览的 `(undeclared)` 仅表示没有声明 auth；旧式中间件仍可能做认证。
+外发文档可用 export；项目内受生成器管理的 `docs/openapi.json` 请通过 generate 更新，以同步文件哈希。

 # Changelog
 
+## v0.7.0-preview.1
+
+- `.api` 支持集中业务错误目录、组级与路由级错误声明，生成状态/错误码/提示一致的 `internal/apierrors` 函数，以及 OpenAPI 命名响应示例。
+- 具名鉴权声明支持 Bearer、header/cookie API key，关联真实中间件；支持组级继承、单路由覆盖与公共接口，认证 hook 优先执行并在启动时校验。
+- 新增多行 `@doc` 的摘要、描述、标签与弃用标记，`info.description` 同步文档。
+- 新增 `api inspect`、`api export`、`api generate --dry-run`；项目内自动识别 manifest 的 API 入口，减少重复参数。
+- 用户示例用真实 401/403/409 验证声明与行为，业务直接使用生成的错误函数；生成不会改写现有手写 hook 和 Service。
+- 纠正旧文档误将事务 Outbox、分布式锁列为已实现的描述；这两个模块当前没有实现。
+
 ## v0.7.0-preview
 
 - 新增 `.api` 契约驱动生成器：DTO、严格多来源绑定与校验、路由、分组 Handler / Service / Repository、命名中间件及 OpenAPI；生成文件哈希管理、业务文件保护和只读 `--check`。
 - `new --api` / `api new` / `api generate` 可以组合 MySQL、日志以及 Local / S3 / R2 / OSS。保存初始基础设施选项，重生成自动沿用；显式切换已有项目选项会拒绝，避免静默丢失初始化代码。
 - 新增 `examples/userService` 独立业务示例与 `verifyAPIWorkflow.py`：用户 CRUD / 分页、管理员 Token 鉴权、MySQL 事务审计、故障回滚、文件导出、requestId 日志、数据库 readiness 和优雅退出；支持从远程版本验收。
 - 日志新增文件轮转、结构化敏感字段脱敏、异常堆栈及慢请求配置；存储新增统一上传策略、直传签名和云端分片能力。
-- 新增缓存、HTTP 客户端、限流 / 幂等 / 超时、后台任务、Redis 队列、事务 outbox、分布式锁、审计、迁移与 telemetry 等可选模块；业务身份与 Orbit 保持由应用自行组合。
+- 新增缓存、HTTP 客户端、限流 / 幂等 / 超时、后台任务、Redis 队列、审计、迁移与 telemetry 等可选模块；业务身份与 Orbit 保持由应用自行组合。

 - 修复 native 在业务层提前拒绝请求体为 413 时等待继续读取 body 的问题，拒绝后关闭未读连接。

+OpenAPI 的数据类型、鉴权和业务错误均来自契约；401/403/404/409 带具体命名示例。业务使用生成的 `apierrors.UserNotFound()`、`apierrors.EmailTaken()` 等函数。
 
 创建、更新、删除都会在**同一个 MySQL 事务**写入 user_audit；审计写入失败时业务变更一起回滚。
 事务提交后才写成功业务日志，requestId 同时出现在 HTTP 响应、业务日志和审计记录。

+# API 错误、鉴权声明与开发体验验收
+
+目标版本：`v0.7.0-preview.1`。本轮修改 CLI 和示例，不改变网络适配器或业务 Service 的调用接口。
+
+## 完成范围
+
+- `.api` 集中声明业务错误，可通过 import 拆分；组级继承、路由追加/清空，生成错误码常量和每次返回新实例的 `apierrors` 函数。
+- bearer、header API key、cookie API key 声明关联实际命名中间件；鉴权先于普通中间件执行，支持单接口覆盖和公共接口。
+- OpenAPI 同步安全方案、401/403/409 等响应、同状态多个错误示例及业务错误码；支持接口描述、标签、弃用标记。
+- 项目根目录自动发现契约入口；`api inspect` 查看路由，`api export` 输出文档，`api generate --dry-run` 预览文件变更。
+- 用户示例使用同一份错误声明，并增加只读凭证，实际覆盖未认证 401、写入被拒绝 403、重复邮箱 409。
+
+## 本地验证
+
+- 完整框架 `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -p=2 -count=1 -timeout=300s ./...`：39 个有测试的包通过。
+- 包含 10 种 API 基础设施组合、10 种既有 CRUD 模块组合，以及新增的错误/鉴权消费者项目实际编译、运行与 race 检查。
+- CLI 最后补充路径参数前缀回归（`:id` 和 `:idLong`），再次执行 `go test -race ./cmd/go-omni/...` 通过。
+- `go vet ./...`、`go build ./...` 和格式/差异检查通过。
+- 现有 API 真实 HTTP 回归在 nethttp/native 共 54 项通过。
+- 用户示例在真实临时 MySQL 下，nethttp/native 共 34 项 HTTP、业务和生命周期检查通过；事务提交/回滚、初始化失败清理等测试同时通过。
+- 检查鉴权优先顺序、未实现 hook 拒绝放行、缺失 hook 时不注册任何路由、公共接口覆盖、多鉴权方案和错误实例独立性。
+- 检查只读预览不创建目录/锁文件、不改变文件；重复生成保留业务实现；无效声明报告源文件位置；恶意 manifest 路径被拒绝。
+
+证据：[完整框架测试](apiDeveloperExperienceTests.txt)、[本地业务报告](apiDeveloperExperienceLocal.json)、[API 基础回归](apiGenerationLocal.json)。
+
+## 远程版本验证
+
+发布后执行以下命令，从全新 module cache 下载 CLI 和框架，验证固定版本且没有本地 replace 的业务项目：
+
+```sh
+python3 scripts/verifyAPIWorkflow.py --version v0.7.0-preview.1 \
+  --report performance/apiDeveloperExperienceRemote.json
+```
+
+远程结果在实际完成后记录；本地通过不代替远程下载验证。
+
+## 边界
+
+鉴权声明负责文档及路由中间件装配；凭证校验、登录和权限策略仍由业务 hook 实现。新 hook 默认返回 501，不会自动放行。
+错误声明不会自动映射数据库错误，也不会拦截运行时返回；Service 需要使用对应错误函数。
+本版每个接口只选择一个认证方案，不含 OAuth2 scopes、组合认证或 SDK 生成；现有 `.api` 继续支持，新声明需升级 CLI。
+
+验收只使用本机临时服务和 MySQL 容器，限制 1 CPU / 768 MiB、绑定 localhost，结束删除临时资源；未使用业务服务器。
+OSS/R2 云账号验收与网络层长时间压力测试不属于本轮。
