云客经营管理后台·批次A（数据底座）实施计划

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 落地经营管理后台的数据底座——6 张新表、首响事实跨日精确计算、员工指标宽表生成、两条回填 CLI，全部带判别性测试。

Architecture: 不动现有写钩子与两张汇总表；新增 first_reply_fact（跨日精确串）+ employee_metric_daily（1:1 口径宽表）+ employee_call_daily（通话小表）三张数据表与三张业务表（评分配置/快照/辅导，本批次只建模型不写业务逻辑）。依据 spec：2026-09-08-yunke-management-console-implementation-v2.md §1-§4、§9（本计划 = v2 的 Task 0-2 展开；评分/异常/API/前端在批次 B-F 另出计划）。

Tech Stack: Python 3.12 + FastAPI + SQLAlchemy 2.0 async + Alembic；测试 pytest + 内存 SQLite（StaticPool）；生产 MySQL 8.4（本地 Docker，DB_URL 已在 .env 指向 mysql+asyncmy://yunke:yunke@localhost:3307/yunke）。

执行者必读：关键代码事实与口径

日切 vs 跨日：app/storage/summary.py _thread_stats 是日切近似——客户 23:00 发、员工次日 9:00 回的场景整条样本丢失（Day1 串不闭合、Day2 重起算无客户消息）。本计划的 compute_conversation 按会话全历史计算，跨夜串不丢（spec §1.1 #1）。
混合口径：app/storage/staff_summary.py 聚合的 sent/recv/threads/answered/fr 无 kind 过滤 = friend+room 混合。宽表消息计数列/串类列一律 friend-only（spec §1.1 #2）。
同源原则：宽表串类三列与 fact 行出自同一个 compute_conversation 调用——回复率分子分母一致（spec §1.1 #5）。
通话无渠道：PhoneCall.channel 是通话类型（phone_call/voice_call）非消息渠道（models.py:512 docstring），通话进独立小表 employee_call_daily(day, user_id)（spec §1.2 #9）。
员工主数据 = staff 表（user_id PK + is_on_job，models.py:126）。幽灵员工（account_map 映射不上或不在 staff）过滤不落宽表（spec §1.3 #11）。
day 口径：Asia/Shanghai 自然日 yyyymmdd，一律 Python 计算（复用 app.storage.summary.day_key），不用 SQL 日期函数。
生命周期口径（spec §1.1 #3 + v1 §21 默认）：new=首次沟通≤7 天；reactivated=当日回流且前次间隔>30 天；active=最近互动≤6 天；cooling=7~29 天；dormant=≥30 天且历史消息≥5 条（对齐 churn real 的 min_msgs=5）。customer 归属用 owner_account_id→account_map→user_id（当前归属口径，换人后归新员工）。
测试命令（Windows venv，在 yunke-server/ 下）：.venv/Scripts/python.exe -m pytest tests/<file> -v。提交信息用中文 conventional 风格（参考 git log）。仓库 master 单主干，直接在 master 提交（项目惯例，不用 worktree）。
本地起服务前先查 Docker：yunke-backend-1/frontend-1 容器占 8000/5173，需保持 stopped（docker stop yunke-backend-1 yunke-frontend-1；mysql/scheduler 常驻）。

Task 0: 五项核实 + 回测名单（不改代码）

Files:

Create: docs/superpowers/plans/2026-09-08-management-batch-a-verification.md
Step 1: 确认本地 MySQL 容器名与连通

docker ps --format '{{.Names}}'   # 期望看到 yunke-mysql-1（常驻）

以下 SQL 用 docker exec -it yunke-mysql-1 mysql -uyunke -pyunke yunke -e "<SQL>" 执行。

Step 2: 核实①员工主数据（staff 表）

SELECT COUNT(*) AS total, SUM(is_on_job=1) AS on_job FROM staff;
SELECT COUNT(DISTINCT user_id) FROM wechat_account WHERE user_id IS NOT NULL;
SELECT COUNT(DISTINCT user_id) FROM whatsapp_account WHERE user_id IS NOT NULL;

期望：staff 总数≈41；账号表 user_id 全部能落在 staff（SELECT COUNT(*) FROM wechat_account w LEFT JOIN staff s ON w.user_id=s.user_id WHERE w.user_id IS NOT NULL AND s.user_id IS NULL 应为 0 或极少——不为 0 时记录哪些幽灵账号）。

Step 3: 核实②phone_call 列与单位

SHOW COLUMNS FROM phone_call;
SELECT channel, COUNT(*) FROM phone_call GROUP BY channel;
SELECT call_id, channel, user_id, call_number, start_call_time, call_duration, incoming_call
FROM phone_call ORDER BY start_call_time DESC LIMIT 10;
SELECT COUNT(*) AS total, SUM(call_duration) AS dur_sum, AVG(call_duration) FROM phone_call WHERE call_duration IS NOT NULL;

判定并记录：call_duration 单位（秒/毫秒——对照已知总量约 73 小时/3,190 条 ⇒ 均值≈82 秒）；call_status/incoming_call 取值分布（后续 Batch B 接通率可能用）；start_call_time 是否毫秒 epoch。

Step 4: 核实③customer 归属字段填充率

SELECT COUNT(*) AS total,
       SUM(user_id IS NOT NULL) AS uid_fill,
       SUM(owner_account_id IS NOT NULL) AS owner_fill,
       SUM(delete_flag=1) AS deleted
FROM customer;
SELECT channel, COUNT(*), SUM(owner_account_id IS NOT NULL) FROM customer GROUP BY channel;

记录：owner_fill 比例（决定生命周期归属覆盖面）；user_id 列与 owner_account_id→account_map 两条路径是否一致（抽 5 行比对）。默认走 owner_account_id 路径。

Step 5: 核实④群占比（量化混合口径偏差）

SELECT channel, peer_kind, COUNT(*) AS rows_cnt,
       SUM(send_cnt+recv_cnt) AS msgs, SUM(cust_threads) AS threads
FROM msg_daily_stats GROUP BY channel, peer_kind;

记录 friend vs room 的 threads 占比——这就是现有看板首响/回复率被群污染的程度（写进核实文档，Batch C 上线时口径说明引用）。

Step 6: 核实⑤call_followup join 键（voice_call 客户号能否对上消息 talker）

SELECT COUNT(*) FROM phone_call p
WHERE p.channel='voice_call' AND p.call_number IS NOT NULL
  AND EXISTS(SELECT 1 FROM message m WHERE m.talker_id = p.call_number
             AND (m.room_id IS NULL OR m.room_id=''));

记录命中率。低于 50% 时：call_followup_count 一期标记低置信（列照建，口径注明）。

Step 7: 选定 3-5 名回测员工

SELECT user_id, SUM(msg_sent+msg_recv) AS msgs FROM stat_daily_staff GROUP BY user_id ORDER BY msgs DESC LIMIT 5;
SELECT user_id, SUM(msg_sent+msg_recv) AS msgs FROM stat_daily_staff WHERE channel='whatsapp' GROUP BY user_id ORDER BY msgs DESC LIMIT 3;
SELECT user_id, SUM(active_rooms) AS rooms FROM stat_daily_staff GROUP BY user_id ORDER BY rooms DESC LIMIT 3;
SELECT user_id, SUM(msg_sent+msg_recv) FROM stat_daily_staff GROUP BY user_id ORDER BY 2 ASC LIMIT 5;  -- 低样本

覆盖：微信为主 1 名、WA 为主 1 名、群运营为主 1 名、高负载 1 名、低样本 1 名（可合并）。

Step 8: 写核实文档并提交

把 Step 2-7 结果写入 docs/superpowers/plans/2026-09-08-management-batch-a-verification.md（含每项结论 + 与本计划默认假设的偏差；偏差影响后续任务实现细节的，在对应任务执行时按核实结论调整并在提交信息注明）。

git add docs/superpowers/plans/2026-09-08-management-batch-a-verification.md
git commit -m "docs(management): 批次A Task0核实记录——phone_call/customer/staff/群占比/回测名单"

Task 1: 6 张表模型 + make_session fixture + 冒烟测试

Files:

Modify: yunke-server/tests/conftest.py（追加 make_session fixture）
Modify: yunke-server/app/db/models.py（文件末尾 SensitiveScanState 之后追加 6 个类；__all__ 按字母序插入 6 个名字）
Test: yunke-server/tests/test_management_models.py
Step 1: conftest 追加存储层测试 fixture

在 tests/conftest.py 末尾追加（import 区已有 async_sessionmaker/create_async_engine/StaticPool）：

@pytest.fixture
async def make_session() -> AsyncIterator[AsyncSession]:
    """独立内存 SQLite AsyncSession(不挂 API 依赖)——存储层/管理域测试用。

    与 make_client 共用 StaticPool 单连接模式;每个测试独享全新 schema。
    """
    engine = create_async_engine(
        "sqlite+aiosqlite:///:memory:",
        poolclass=StaticPool,
        connect_args={"check_same_thread": False},
    )
    async with engine.begin() as conn:
        await conn.run_sync(Base.metadata.create_all)
    SessionLocal = async_sessionmaker(engine, expire_on_commit=False)
    async with SessionLocal() as s:
        yield s
    await engine.dispose()

Step 2: 写模型冒烟测试（先失败）

新建 tests/test_management_models.py：

"""管理域 6 张新表的模型冒烟测试(批次A Task1)。

只验证:建表可用、主键/唯一约束生效、默认值正确。业务逻辑在

cd yunke-server && .venv/Scripts/python.exe -m pytest tests/test_management_models.py -v

期望：8 passed。

Step 6: 全量回归

Task 2: Alembic migration

cd yunke-server && .venv/Scripts/python.exe -m alembic heads

期望 f7a8b9c0d1e2（customer_account_link 是当前链尾；若执行时又有新迁移合入，把迁移文件的 down_revision 改成实际 head）。

Step 2: 写迁移文件

照 f0a1b2c3d4e5_analytics_module_tables.py 的幂等守卫模式（sa.inspect 先查后建；不在 migration 里碰 message/msg_daily_stats 数据）：

注意：updated_at 无 alembic 服务端 onupdate（模型 _updated_at() 是 Python 侧 onupdate，迁移里静态 now() 即可——与 f0a1b2c3d4e5 同做法）。

Step 3: 本地库升级实测

cd yunke-server && .venv/Scripts/python.exe -m alembic upgrade head

期望：输出包含 Running upgrade f7a8b9c0d1e2 -> b7c8d9e0f1a2。再跑一次（幂等）应无操作。

Step 4: 验证表存在 + downgrade 冒烟

docker exec -it yunke-mysql-1 mysql -uyunke -pyunke yunke -e "SHOW TABLES LIKE '%employee%'; SHOW TABLES LIKE '%first_reply%'; SHOW TABLES LIKE '%management%';"
cd yunke-server && .venv/Scripts/python.exe -m alembic downgrade -1 && .venv/Scripts/python.exe -m alembic upgrade head

期望：6 张表存在；downgrade 后消失、再 upgrade 恢复。

Step 5: 全量测试 + 提交

cd yunke-server && .venv/Scripts/python.exe -m pytest tests/ -q
git add yunke-server/migrations/versions/b7c8d9e0f1a2_management_phase1_tables.py
git commit -m "feat(management): 批次A建表迁移——六表幂等守卫/索引独立补齐/downgrade只删新表"

                        fr_sum_ms=t["fr"],
                        first_reply_p50_ms=_percentile(frs.get(key, []), 0.5),
                        first_reply_p90_ms=_percentile(frs.get(key, []), 0.9),
                        new_customer_count=lv.get("new", 0),
                        cooling_customer_count=lv.get("cooling", 0),
                        dormant_customer_count=lv.get("dormant", 0),
                        reactivated_customer_count=lv.get("reactivated", 0),
                        data_complete=True,
                    )
                )
                written += 1
            await session.flush()  # 防御性:防 autoflush=False 配置下 ORM 对象堆积(Task6 评审修正)
    return written

注意实现要点（执行者核对）：

load_conversation 在 Task 3 已公有定义——宽表生成 import 复用，保证串类列与 fact 行同源同加载口径；
_percentile 的最近邻秩公式与测试对齐（若写 math.ceil 版本更清晰可替换，测试只断言行为）；
幂等删除条件带 metric_version == METRIC_VERSION，其他版本行不受影响。
Step 4: 跑测试通过 + 全量回归

cd yunke-server && .venv/Scripts/python.exe -m pytest tests/test_employee_metrics.py -v
cd yunke-server && .venv/Scripts/python.exe -m pytest tests/ -q

期望：6 passed（通话 2 + 宽表 4）；全量绿。

Step 5: 提交

git add yunke-server/app/storage/employee_metrics.py yunke-server/tests/test_employee_metrics.py
git commit -m "feat(management): 员工指标宽表——1:1口径/串类与fact同源/生命周期列/幽灵过滤"

Task 7: 两条回填 CLI

Files:

Modify: yunke-server/app/sync/cli.py
Step 1: 注册子命令（_build_parser 的 sensitive-scan 之后）

    # ``first-reply-facts`` ----------------------------------------------
    p_fr = sub.add_parser(
        "first-reply-facts",
        help="Rebuild first_reply_fact (cross-day exact threads).",
        description=(
            "Full rebuild of the first-reply fact table from the message "
            "table (cross-day exact thread algorithm — overnight samples "
            "not lost, unlike msg_daily_stats day-cut). Deploy backfill + "
            "nightly self-heal step. Idempotent."
        ),
    )

    # ``employee-metrics`` ------------------------------------------------
    p_emp = sub.add_parser(
        "employee-metrics",
        help="Rebuild employee_metric_daily + employee_call_daily.",
        description=(
            "Full rebuild of the management wide table (per-day x channel "
            "x staff, 1:1 caliber) and the call daily table. Must run "
            "AFTER first-reply-facts (thread columns share the same "
            "source). Deploy backfill + nightly self-heal. Idempotent."
        ),
    )

Step 2: 实现命令函数（_cmd_sensitive_scan 之后）

async def _cmd_first_reply_facts(args: argparse.Namespace) -> int:
    """全量重建 first_reply_fact(跨日精确串;部署回填/夜间自愈,幂等)。"""
    settings = get_settings()
    engine, session_maker = await _init_db(settings.db_url)
    try:
        from app.storage.first_reply_facts import recompute_all

        async with session_maker() as session:
            pairs = await recompute_all(session)
            await session.commit()
        print(f"[first-reply-facts] rebuilt {pairs} conversations")
        return 0
    finally:
        await engine.dispose()


async def _cmd_employee_metrics(args: argparse.Namespace) -> int:
    """全量重建 employee_metric_daily + employee_call_daily(幂等)。"""
    settings = get_settings()
    engine, session_maker = await _init_db(settings.db_url)
    try:
        import sqlalchemy as sa

        from app.db.models import MsgDailyStats
        from app.storage.employee_metrics import (
            recompute_call_days,
            recompute_metric_days,
        )

        async with session_maker() as session:
            days = (
                await session.execute(sa.select(MsgDailyStats.day).distinct())
            ).scalars().all()
            rows = await recompute_metric_days(session, list(days))
            calls = await recompute_call_days(session, list(days))
            await session.commit()
        print(
            f"[employee-metrics] rebuilt {rows} wide rows, {calls} call rows"
        )
        return 0
    finally:
        await engine.dispose()

main() 分发表追加两行（sensitive-scan 之后）：

        if args.command == "first-reply-facts":
            return asyncio.run(_cmd_first_reply_facts(args))
        if args.command == "employee-metrics":
            return asyncio.run(_cmd_employee_metrics(args))

Step 3: 冒烟验证（对本地 Docker MySQL 真跑）

cd yunke-server && .venv/Scripts/python.exe -m app.sync.cli first-reply-facts
cd yunke-server && .venv/Scripts/python.exe -m app.sync.cli employee-metrics

期望：退出码 0，输出会话数（预期数千）与行数（宽表预期 = 活跃 day×channel×员工组合，数千~数万）。

Step 4: 幂等复跑 + 抽查

cd yunke-server && .venv/Scripts/python.exe -m app.sync.cli employee-metrics  # 复跑行数应一致
docker exec -it yunke-mysql-1 mysql -uyunke -pyunke yunke -e "
SELECT COUNT(*) AS fact_rows FROM first_reply_fact;
SELECT COUNT(*) AS wide_rows, SUM(threads_answered) AS answered FROM employee_metric_daily;
SELECT COUNT(*) FROM first_reply_fact f
WHERE NOT EXISTS (SELECT 1 FROM msg_daily_stats m
  WHERE m.peer_kind='friend' AND m.channel=f.channel
    AND m.owner_account_id=f.owner_account_id AND m.peer_id=f.peer_id AND m.day=f.day);
"

期望：第三个查询返回 0（每个 fact 样本所在会话×日都有 msg_daily_stats 行——落库链路自洽）。

Step 5: 全量测试 + 提交

cd yunke-server && .venv/Scripts/python.exe -m pytest tests/ -q
git add yunke-server/app/sync/cli.py
git commit -m "feat(management): 两条回填CLI——first-reply-facts/employee-metrics全量重建幂等"

Task 8: 本地全量回填实测 + 对账 + DEPLOY.md 注记

Files:

Modify: docs/DEPLOY.md（§7 回填清单追加两条命令）
Modify: docs/superpowers/plans/2026-09-08-management-batch-a-verification.md（追加实测数据）
Step 1: 计时全量回填

cd yunke-server && time .venv/Scripts/python.exe -m app.sync.cli first-reply-facts
cd yunke-server && time .venv/Scripts/python.exe -m app.sync.cli employee-metrics

记录耗时到核实文档（预期：fact 分钟级、宽表分钟级；超过 10 分钟时记下瓶颈会话，评估尾部增量优化——不阻塞批次验收）。

Step 2: 对账抽查（v2 §9 数据核验的批次A子集）

用 Task 0 回测名单中的 2 名员工 × 3 个日期：

-- 1) 消息计数列 ↔ msg_daily_stats friend 聚合(必须一致)
SELECT m.day, SUM(m.send_cnt) sent, SUM(m.recv_cnt) recv
FROM msg_daily_stats m JOIN wechat_account w ON m.owner_account_id=w.wx_id
WHERE m.peer_kind='friend' AND w.user_id='<UID>' AND m.day IN (20260901, 20260815, 20260801)
GROUP BY m.day;
SELECT day, msg_sent, msg_recv FROM employee_metric_daily
WHERE user_id='<UID>' AND channel='wechat' AND day IN (20260901, 20260815, 20260801);
-- 2) 串类列 ↔ fact 行数(必须一致——同源)
SELECT f.day, COUNT(*) FROM first_reply_fact f JOIN wechat_account w ON f.owner_account_id=w.wx_id
WHERE w.user_id='<UID>' AND f.day IN (...) GROUP BY f.day;
SELECT day, threads_answered FROM employee_metric_daily WHERE user_id='<UID>' AND ...;
-- 3) 串类列 vs 日切口径(允许 fact ≥ 日切——差集=跨夜串,记录差值)
SELECT day, cust_threads FROM stat_daily_staff WHERE user_id='<UID>' AND ...;

把对账结果（一致/差异+解释）写入核实文档。发现不一致且无法用口径差异解释时停下排查，不得带病进入批次B。

Step 3: DEPLOY.md §7 追加回填注记

在现有 daily-stats/staff-daily-stats 回填注记之后追加（格式对齐现有条目）：

- 管理后台批次A新增（部署带迁移 b7c8d9e0f1a2 后各跑一次，幂等）：
  - `python -m app.sync.cli first-reply-facts`（跨日精确首响事实；本地实测耗时见批次A核实文档）
  - `python -m app.sync.cli employee-metrics`（员工宽表+通话小表；**必须在 first-reply-facts 之后跑**）
  - 服务器注意：backend 容器不自动跑 alembic，须手动 `sudo docker exec <backend> alembic upgrade head`

Step 4: 提交 + 批次收尾

git add docs/DEPLOY.md docs/superpowers/plans/2026-09-08-management-batch-a-verification.md
git commit -m "docs(management): 批次A回填实测+对账记录+DEPLOY部署注记"

批次A验收清单（全部勾完才算完成）

6 张表在本地 MySQL 存在，migration 幂等 + downgrade 干净；
first-reply-facts 全量回填成功且复跑幂等；
employee-metrics 全量回填成功且复跑幂等；
跨夜串判别测试通过（23:00→次日 9:00 产生 ~10h 样本）；
friend-only 口径判别测试通过（room 不进消息计数/串列）；
同源判别测试通过（threads_answered ≡ fact 行数；多日未回串分母不膨胀）；
幽灵员工过滤测试通过；
对账抽查：消息计数列与 msg_daily_stats friend 聚合一致；串类列差异全部可用跨夜串解释；
全量测试套件绿（现有 ~575 + 新增 30：模型 8 + fact 9 + lifecycle 7 + 通话/宽表 6）；
核实文档完整（五项核实 + 回测名单 + 回填耗时 + 对账记录）；
写钩子零改动（git diff 确认 summary.py/repos.py 未动）。

批次B-F 的后续计划

批次A合入后另出计划（避免远期细节空转）：

批次B（v2 Task 3-5）：scoring/anomalies/管理 API + 配置种子 CLI；
批次C（Task 6-7）：前端导航+管理驾驶舱；
批次D（Task 8-9）：员工总览+详情；
批次E（Task 10-11）：辅导闭环+考核快照；
批次F（Task 12-13）：analytics_tick 第三步、full_sync 第 13/14 步、scheduler 镜像重建、回测试运行。
