- Base platform from base.git (ERP base: auth, core, config, message, workflow, plugin) - Created erp-diary module skeleton (lib.rs, dto.rs, error.rs, event.rs, state.rs) - Integrated erp-diary into workspace and erp-server - Added DiaryModule registration in main.rs - Added DiaryState FromRef in state.rs - Diary routes mounted (empty routes, ready for implementation) - Product design spec v1.2 preserved in docs/ - Implementation plan preserved in plans/ Cargo check: OK Cargo test: OK (78+ base tests passing)

//! 聚合查询容错工具
|
|
//!
|
|
//! 仪表盘等聚合统计端点通常包含多个独立子查询。
|
|
//! 单个子查询失败不应导致整个接口 500。
|
|
//! `safe_aggregate` 让每个子查询独立容错，失败时返回默认值并记录警告日志。

|

///
|
|
/// 仪表盘统计 API 聚合多个指标（患者数/咨询数/随访数等），

/// 任一子查询失败不应阻塞其他指标返回。

/// stats_service::get_patient_statistics(&state, tenant_id),
