fix(memory-projection): 订正 outbox 取值口径并接通画像投影链路
背景:memory_sync_outbox 这条链此前**完全没有消费者**,且生产端照 docs/00 §6.4.6
写成大写 MILVUS/NEO4J + 中文「待处理」,而消费端按 target_store 的**值**分派 handler、
且只领 status in {pending, failed} —— 两个条件都不满足,事件任何消费者都领不到、
永久滞留且不报错(唯一键 (event_uuid, target_store) 对大小写无约束,MySQL 也不报错)。
根因是代码与测试都硬编码字面量,所以测试跟着一起错、谁也没拦住。
订正
- profile_generation_service:取值改为全仓一致的小写(milvus/neo4j/upsert/pending)
- 测试改为引用常量并断言消费端契约,不再硬编码(硬编码是本次跑偏的直接原因)
- 新增契约回归测试:断言大写值分派不到 handler、会进死信,谁改回大写立刻红
- 新增 tools/normalize_memory_sync_outbox.py:订正历史脏行(默认 dry-run、幂等)
接通投影链路(此前零消费者)
- 新增 Milvus 集合 user_long_term_memory_v1 及建集合工具(幂等、不覆盖已有集合)
- 新增 MilvusProfileProjection / MilvusProfileVectorClient,并修掉移植带来的两处必炸点:
customer_id 由「必须 int」放宽为接受数字字符串(本仓所有生产者都写 str,
不放宽则每个事件必然失败);不可投影的 memory_key 由「整批 raise」改为跳过留痕
(否则一条 constraint: 记忆毒死该客户整批,而受控词表 13 个键里有 7 个不满足前缀)
- 新增 MemorySyncOutboxWorker(领取/指数退避/死信骨架保留原样)并接入 WorkerRuntime
- milvus → 向量投影;neo4j → 复用主干 ProfileGraphProjectionService(方案 A,
不引入第二套投影,避免同一事实在图中两种说法、违反主干既有的只投影已确认事实的不变式)
- 生产端从 memory_unit(status=active) 组装 memory_sources,随事件带上确定快照
- 前置移植 conversation_privacy:写外部存储前脱敏手机号/证件号/银行卡等
验证
- 新增 17 个单测;全量 2 failed, 1307 passed, 2 skipped
(2 个失败为既有环境项:断言请求体中文原文而 httpx 序列化成 \uXXXX,非本次引入)
- mypy app → 0 错(227 文件);audit_schema → 89 张业务表无缺失/意外,未改动表结构
- 真机:真实 embedding(1024 维) + 真实 Milvus 写入并回读通过
- 整合链路(测试记忆 → 生产端组装 → outbox → 消费端投递 → Milvus 回读)通过,
且 MySQL 已回滚、Milvus 无残留
文档
- 新增 docs/32-记忆投影链路实现说明.md:真实口径、根因、契约与验证证据(供接手)
- AGENTS.md:新增该易错点;新增 Windows 中文输出乱码的正确命令(-X utf8);
校正测试基线与 mypy 文件数
未做:未改 docs/00 基线、未动数据库迁移、未改投顾线代码、未启动常驻 Worker。
遗留:投顾线两处生产者的 payload 缺 memory_sources,会被消费至死信,待架构师确认是否投影。

"""数据订正:把 `memory_sync_outbox` 的历史取值改齐为全仓小写口径。
|
||||
|
||||
**默认 dry-run**(只报告将影响几行),加 `--apply` 才真正提交。幂等,可重复运行。
|
||||
|
||||
### 背景
|
||||
|
||||
`docs/00` §6.4.6 的取值栏曾写作大写 `MILVUS`/`NEO4J`、`UPSERT` 与中文 `待处理`,
|
||||
与全仓实现从未对齐。按那份文档写入的事件会**静默失效**:
|
||||
|
||||
- 消费端 `MemorySyncOutboxWorker` 按 `handlers.get(event.target_store)` 分派 handler;
|
||||
- 领取条件是 `status.in_({"pending","failed"})`。
|
||||
|
||||
大写 + 中文两个条件都不满足 ⇒ 事件任何消费者都领不到、永久滞留且不报错
|
||||
(唯一键 `(event_uuid, target_store)` 对大小写没有约束,MySQL 也不会报错)。
|
||||
|
||||
因此凡是在本仓写入过 `memory_sync_outbox` 的环境,都可能有这类脏行。
|
||||
|
||||
### 安全口径
|
||||
|
||||
- 只改 `target_store` / `operation` / `status` 的**值**;
|
||||
- **不触碰**主键、唯一键 `uk_memory_sync_event (event_uuid, target_store)`、
|
||||
`payload`、时间戳、`retry_count`;
|
||||
- 就地改值不会新增行(两组取值大小写不同,本会各自成行,这里把它们并到正确的一组);
|
||||
- 中文字符不受 `LOWER()` 影响(非 ASCII 字节不变),故 `LOWER()` 是安全的。
|
||||
|
||||

|
||||
.\\.venv\\Scripts\\python.exe tools\\normalize_memory_sync_outbox.py # 先看
|
||||
.\\.venv\\Scripts\\python.exe tools\\normalize_memory_sync_outbox.py --apply # 再改
