Definition
通过数学约束强制执行 Source_Rows == Success_Rows + Quarantine_Rows 的数据修复保证机制。任何不匹配立即触发 Sev-1 告警与系统异常。
Invariant
Source_Rows == Success_Rows + Quarantine_Rows
Row Lifecycle
| State | Description | Destination |
|---|---|---|
AI_FIXED |
SLM 置信度 ≥ 0.75，lambda 验证通过 | Staging → Production |
HUMAN_REVIEW |
置信度 < 0.75，或无法自动修复 | Human Quarantine Dashboard |
Guarantees
- Mathematical constraint, not a goal: 不满足等式时系统立即失败，不允许静默通过
- Full tracking: 每条异常行在修复生命周期中始终被追踪
- No silent corruption: 修复后的数据先到 staging，确认后才写生产
Alert Conditions
if source != success + quarantine:
trigger_alert(severity="SEV1", message=f"DATA LOSS DETECTED: {missing} rows")
raise DataLossException(...)
