"""moldinsight 域模型：老师傅经验反馈表。
|
|||
|
|
|
|||
|
|
Human-in-Loop 闭环（D17，2026-09）：老师傅对系统推荐方案给出"采纳 / 调整 / 拒绝"
|
|||
|
|
反馈，按"产品指纹 + 工艺参数"为索引跨任务匹配；下次同指纹产品分析自动消费
|
|||
|
|
（OCC worker payload 透传 → MultiSchemeMoldPlanner → PartingSchemeScorer 加成）。
|
|||
|
|
|
|||
|
|
跨模块桥接只保留裸 FK，不建 ORM relationship（base.py 约定）：
|
|||
|
|
- processing_task_id -> processing_tasks.id
|
|||
|
|
- stp_file_id -> stp_files.id
|
|||
|
|
- user_id -> users.id
|
|||
|
|
|
|||
|
|
写入 feedback 时由 service 层填充 fingerprint JSON（bbox_aspect / volume_bucket /
|
|||
|
|
face_bucket / undercut_class / material_family / is_foam）。fingerprint 是跨任务
|
|||
|
|
匹配的索引列（PG 下有 GIN 索引支持 jsonb_path_query 类查询）。
