Project Constitution — 愈心谷

最高原则。与本文件冲突时，以本文件为准。

Absolute Laws

1. Architecture never broken. Layers: UI → API → Service → Repository → Database. No skipping.
2. Readability > Cleverness.
3. Deterministic > Magic.
4. Simple > Complex.
5. Explicit > Implicit.
6. No hidden global state.
7. Every module independently testable.
8. Every feature deployable.
9. Every API documented (OpenAPI or apps/docs).
10. Every database change versioned (migration required).
11. Local feedback speed > local environment purity. 本地开发追求分钟级反馈；生产/CI 追求环境一致。二者禁止混用工作流（见 .ai/environment.md）。

Product Laws (YuXinGu)

1. Never invent medical efficacy claims.
2. Never use fortune-telling / 吉凶祸福 wording.
3. Birthday and profile data are sensitive — minimize, authorize, allow delete.
4. Billing and unlock decisions happen on the server, never trust the client alone.
5. New product code lives in apps/ and packages/ only. Legacy root HTML is read-only unless the task is explicit migration.

AI Laws

1. Obey .ai/ai-contract.md every session.
2. Load constitution → architecture → domain before writing code.
3. Never invent APIs/DB/domain words; never reverse Accepted ADRs silently.
4. Never modify files outside the current task scope.
5. Prefer patterns + examples + playbooks over prompts.
6. Prefer small diffs. One feature per change set.
7. Think → architecture check → code → commands → review → DoD.
