批1(A1+A2):管理层要看「每个人的响应质量」。 - 迁移 d9e0f1a2b3c4:msg_daily_stats/stat_daily_staff 各加 cust_threads/threads_answered/fr_sum_ms(NOT NULL server_default 0, 幂等守卫照 9b0d0c133035 惯例;models.py 双声明同步) - summary.py _thread_stats:串=客户连续消息不被员工消息打断的段, is_send=None 不参与串判定;fr=员工首条回复−串末条客户消息; 日切近似 v1(日末未闭合串计 threads 不计 answered,口径写进 docstring) - recompute_days/recompute_all 都先按 ts 排序再算串(乱序防护) - staff_summary 聚合三列按账号→员工累加(fr_cnt≡threads_answered 不单列) - 测试 +10:串算法矩阵 9 例+staff 聚合传递;全量 589 绿 - 本地 86 万行回填验证:daily-stats 60s/staff 10s,rollup 总和与 明细完全一致,随机 5 行 SQL 独立复算全对 Co-Authored-By: Claude Code <noreply@anthropic.com>

数据分析板块批1(A1+A2,2026-09-07):管理层要看「每个人的响应质量」。
|
|
两表各加 cust_threads / threads_answered / fr_sum_ms——消息串算法见
|
|
app/storage/summary.py(口径与 8-24 spec 对齐,日切近似 v1)。
|
|
fr_cnt ≡ threads_answered(被回串数=样本数),不单列。
|
|
|
|
幂等:sa.inspect 先查列存在则跳过(照 9b0d0c133035 惯例,SQLite/MySQL
|
|
通用);downgrade 对称删列。模型侧 models.py 同步双声明,防 alembic
|
|
autogenerate 反 DROP。NOT NULL + server_default 0:旧行/旧构造不传也不炸。
