M6：缘契、人格与世界——契约版本链、铸魂分灵、河图境界与三界分流

- 缘契域 domains/yuanqi：covenants（当前版）+ covenant_events（不可变历史）；提议—问心—铭契—撤回全链；边界变更立即生效；多维关系并存，服务层拒绝 affinity/好感度单一键；浪漫维度成人资格标记位
- 道体铸魂与分灵 domains/jingsheng/soul.py：soul_forgings 确认流（锚点变更 pending→confirmed 应用并签发新魂籍版本，确认前人物锚点不变）；分灵创建新人物（继承资料与谱系 lineage 链、不继承原身份，魂籍从 v1 起）
- 河图域 domains/hetu：persistent_worlds 境界 + world_entities/world_relations 境界作用域重建 + 世谱挂接；境界正史视图（scope=persistent_world 归真集合）；canonize 后置推进正史计数
- 三界分流：reality→息壤提取（不变）；persistent_world→境界实录+正史推进；simulation→只记试演实录；factual_records 增 scope 列——境界/幻境实录与真界本相隔离
- 正影打通：引文 target_type=memory 时被引记忆 superseded → 返回 successor_memory_id 提示，不静默替换
- 前端：人物详情页缘契面板（提议维度选择/铭契/撤回/事件史）+ 世界页重建（境界目录/实体/正史概览）+ covenants/worlds api 库
- 退役：旧 personality/drive/evolution/world 模块、服务、端点、仓储、schema、前端五页与组件样式；迁移 007 退役九张旧表与 characters.current_personality_version_id
- 验收（test_m6_domains 六用例）：多维无单一好感度/铭契版本链/事件不可抹除/撤回立即生效/边界即时/铸魂确认流+魂籍版本/分灵谱系/境界正史不进真界（实录 scope 隔离+真界候选=0）/引文正影后继
- 四套件：后端 379、前端 199、BFF 4、神识 5 包全绿（2 个预存环境失败不变）；迁移 007 净库+±1 干净
