 ## 0. 规格驱动开发（SDD，强制）
 本项目采用 **Specification-Driven Development**。对于会改变行为、接口、数据或运维方式的工作，规格不是完成后的说明，而是实现前的约束和验收依据。
 权威规范与模板：
 - 流程、分级、质量门禁：`docs/specs/README.md`
 - 新规格模板：`docs/specs/_template.md`
 ### 0.1 变更分级
 | 级别 | 典型范围 | 规格要求 |
 |------|----------|----------|
 | S0 | 文案、注释、格式、无行为变化的机械修改 | 不创建规格文件，但必须验证受影响文件 |
 | S1 | 局部缺陷修复、内部重构、单模块小改动 | 在任务计划中写清问题、约束、验收标准 |
 | S2 | 新功能、跨模块流程、API/数据模型/配置变更 | 实现前必须创建或更新 `docs/specs/<domain>/<slug>.md` |
 | S3 | 认证授权、账单、安全、数据库迁移、数据清理、生产部署 | 按 S2 执行，并补充风险、兼容性、可观测性、发布与回滚方案 |
 级别取最高影响，不以代码行数判断。用户已给出明确需求时可以直接形成规格并继续；只有缺失选择会显著改变结果或扩大权限时才暂停询问。
 ### 0.2 强制工作流
 1. **Discover**：先读现有代码、接口、模型、测试和工作区差异，以证据确认当前行为。
 2. **Specify**：写清目标、非目标、行为规则、接口/数据契约、验收标准和风险；S2/S3 必须落盘。
 3. **Design**：确定最小实现边界、复用点、迁移和回滚路径，禁止把未决问题留给编码阶段猜测。
 4. **Implement**：按规格逐项实现；发现规格错误时先更新规格，再改代码，禁止静默偏离。
 5. **Verify**：每条验收标准必须映射到自动化测试、构建检查或明确的人工验证证据。
 6. **Deliver**：交付说明必须列出实现结果、验证证据、未覆盖项和剩余风险；S2/S3 同步更新规格状态。
 ### 0.3 不可绕过的门禁
 - API 改动必须先明确请求、响应、错误码、权限和兼容策略，再同步前后端。
 - 数据库改动必须使用版本化幂等迁移，说明数据回填、旧版本兼容、备份和回滚；禁止用启动期 `AutoMigrate` 代替生产迁移。
 - 认证、审批、远程执行、账单和密钥相关变更必须包含权限边界、审计行为和失败路径。
 - 监控、Agent 上报、日志等高频数据必须定义保留期、容量影响和清理可观测性。
 - 金额必须明确原币、报告币、汇率来源和精度；时间必须明确时区、统计窗口和边界日期。
 - 新增行为必须有测试。无法自动化的验收项要记录原因、人工步骤和结果，不能用“已检查”代替证据。
 - 实现不得夹带规格外重构；发现必要的额外工作，应先补入规格的范围或后续事项。
 ### 0.4 完成定义（Definition of Done）
 代码编译通过不等于完成。S1 及以上变更至少满足：规格/计划与实现一致、验收标准全部有证据、相关测试通过、错误与空状态可用、权限和兼容性已检查、文档已同步、发布与回滚可执行。任一项缺失时必须明确标记未完成，不得宣称任务已完成。

 ## 规格驱动开发（SDD）
 本仓库强制使用 SDD 管理行为变更。开始编码前先按 `docs/specs/README.md` 判定变更级别并完成对应规格；S2/S3 变更使用 `docs/specs/_template.md` 创建规格文件。
 执行顺序固定为：**Discover → Specify → Design → Implement → Verify → Deliver**。
 - S0：纯文案、格式和无行为变化的机械修改，可不建规格文件。
 - S1：局部修复或单模块小改动，任务计划中必须包含问题、约束和可验证验收标准。
 - S2：新功能、跨模块流程、API、配置或数据模型变更，必须先落盘规格。
 - S3：认证、账单、安全、迁移、清理和生产部署，在 S2 基础上必须提供风险、兼容、可观测、发布和回滚方案。
 硬性要求：
 1. 规格中的验收标准使用稳定编号 `AC-01`，每条必须映射到测试或人工验证证据。
 2. API 先定义请求、响应、错误码和权限；数据库先定义版本化迁移、兼容和回滚；前后端不得各自猜测契约。
 3. 实现与规格冲突时先更新规格再编码，禁止静默偏离或夹带范围外重构。
 4. 金额明确币种/汇率/精度，时间明确时区/窗口，敏感操作明确权限/审计/失败路径，高频数据明确保留与清理策略。
 5. 交付必须报告验证命令、结果、未覆盖项和剩余风险。验收未闭环时不得宣称完成。
 `AGENTS.md` 保存完整项目约束；`docs/specs/README.md` 是 SDD 流程的唯一权威来源。若本文与权威规范冲突，以后者为准。
