迁移草案定义

MigrationDraft 是发布前的核心对象，用于承载迁移结果和审计信息。

字段结构

1. template
   完整模板，包含目标、约束、预测配置、优化配置、安全规则。
2. confidence
   草案置信度，范围 0.0-1.0。
3. pending_confirmations
   需要人工确认的条目。
4. risks
   风险清单。
5. generation_strategy
   生成策略，例如 llm_primary、rule_fallback、catalog_binding。
6. source_mappings
   点位映射列表。
7. trace
   每轮修正记录。
8. llm_metadata
   模型供应商、模型名等元信息。

何时判定可发布

发布前需要同时满足： 1. 模板校验通过 2. 评分阈值检查通过

任一失败都会被阻断。
