 - 2026-07-14 BRD M1 派发场景状态与展示一致性复核：修复停用场景仍可通过直接派发接口进入待训练，以及客户端传入场景名称可与场景 ID 不一致的问题；主管派发现在复用启停校验，记录名称始终取服务端场景定义。历史任务读取不受影响，未修改生产数据。
 - 2026-07-14 BRD M1 场景筛选回退语义复核：场景表查询成功但岗位/类型没有启用场景时，旧逻辑仍回退到内置场景，可能把不匹配或已停用场景展示给员工/主管；现仅在数据库异常时保留 seed fallback，真实空结果保持为空，并补岗位筛选回归测试。未修改生产数据。
 - 2026-07-14 BRD M1 主管场景入口回退复核：后端已启用场景 API 优先，但主管指派页模板仍循环三条静态场景，且 API 正常空结果会继续显示静态选项；现改为循环 API 场景，真实空结果显示“暂无可派发的已启用场景”，只有请求失败才使用本地兜底。复盘后再练入口同步保持真实空结果为空，未修改生产数据。
+- 2026-07-14 BRD 4.4 任务来源展示补齐：首页“今日安排”和练习页“最近练过”此前只把非每日任务显示为场景名/“专项训练”，会遮蔽主管派发的错题再练与训练营来源；现统一显示“每日三题/错题再练/训练营/专项训练”标签。该修复只补来源可见性，不把 `source='camp'` 扩展为尚未确认的训练营计划、进度或完成规则。
+- 2026-07-14 BRD 4.5/B5 训练时长口径修复：能力画像此前用“完成次数 × 8 分钟”估算训练时长，无法作为真实时长证据；现复用 `started_time/finished_time` 按实际秒数聚合并换算分钟，无时间证据的历史记录按 0 计。未新增表字段；正式试点仍需核对时间来源、异常时长和课程学习时长是否纳入统一口径。
