r"""合规层种子数据：7 个零容忍负面词（+4 变体）与 6 类固定话术。
|
||||
|
||||
背景：`docs/02` §10.2/§10.3 要求这些数据，但迁移只建表、没有 seed。而
|
||||
`app/service/agent/governance.py` L62-65 的取数条件是
|
||||
`status='active' AND reviewer_id IS NOT NULL AND reviewed_at IS NOT NULL`，
|
||||
两张表 0 行就意味着一**条规则都查不到**：客服 Agent 说"这只基金稳赚"不会被拦，
|
||||
免责声明也不会出现在任何回复里。合规过滤是静默失效的——不报错，只是不生效。
|
||||
|
||||
取值来源（不臆造，均以真实 DDL 为准）：
|
||||
- `agent_negative_word.match_type` CHECK：`exact` / `contains` / `regex`，
|
||||
这里只用 `contains`；`regex` 被 governance.py L75-77 显式拒绝
|
||||
（Python `re` 无执行超时，底座不跑未经约束的管理员正则）。
|
||||
- `agent_negative_word.severity` CHECK：`warn` / `regenerate` / `block`，
|
||||
零容忍词一律 `block`。
|
||||
- `agent_negative_word.category` **无 CHECK 约束**，按语义取值（《理财销售办法》
|
||||
的口径：误导性 / 绝对化 / 承诺 / 收益）。
|
||||
- `agent_reply_template.scene` CHECK：`disclaimer` / `low_confidence` /
|
||||
`compliance_block` / `transfer` / `model_failure` / `system_busy` / `clarification`。
|
||||
- `agent_reply_template.active_key` 是 **生成列**（`status='active'` 时等于
|
||||
`template_code:locale`，否则 NULL）：不能写、也不该写，由库自己算。
|
||||
它上面有唯一键 `uk_reply_template_active_one`，所以同一 template_code 只能有一条 active。
|
||||
|
||||
幂等：按 `rule_code`（唯一键 `uk_negative_rule_code`）与
|
||||
`template_code`+`version`（唯一键 `uk_reply_template_version`）upsert，可重复执行；
|
||||
重复执行不会新增行，只会把已存在的行重新置为 active 并刷新审核信息。
|
||||
|
||||
执行：`.\.venv\Scripts\python.exe tools\seed_compliance_baseline.py`（可重复执行）
