- 前端只做表现、交互和临时 UI 状态，不承接正式业务真相，不绕过后端投影或后端 API 直接实现业务规则。
- 契约、路由、DTO 去留和 breaking change 以当前后端架构文档、`server-rs/crates/api-server/src/app.rs`、`shared-contracts` 和 `packages/shared` 为准；不得在前端、`api-server` 或临时兼容层中重新发明旧接口。

 - SpacetimeDB 已有表新增字段时，字段必须放在 Rust 表结构体最后，并设置明确默认值；需要删除、改名、重排或改类型时，必须先询问用户并确认迁移计划。
