关系与情绪¶

目的¶

Relationships 和 emotions 让社交与情感状态在图中显式化。EntityRelationship 节点描述实体之间带类型的关系，可带 private visibility 和 evidence。EmotionState 节点存储角色的 baseline 与 immediate emotion vectors。Audit nodes 解释关系或情绪状态为什么变化。

重要属性¶

实体	重要属性
`EntityRelationship`	`id`, `scope_type`, `scope_id`, `source`, `target`, `label`, `public_description`, `private_description`, `visibility`, `perspective_character_id`, `confidence`, `details`, evidence memory ids, timestamps, `version`, `active`
`EmotionState`	`id`, `simulation_id`, `character_id`, `baseline`, `immediate`, half-life seconds, `last_updated_at`, `version`
`EmotionVector` value	`valence`, `arousal`, `dominance`, free-form dimensions
`RelationshipChangeAudit`	relationship id, turn id, perspective character id, evidence memory ids, timestamps
`EmotionChangeAudit`	emotion state id, turn id, evidence memory ids, caused-by events

归属与生命周期¶

Relationships 以 world 或 simulation 为作用域。World-scoped relationships 是作者态背景事实。Simulation-scoped relationships 是运行时事实，可以引用继承的 world entities 或 simulation entities。

Emotion state 属于 simulation scope，由 character 拥有。随着 turns 不断产出新的 events 和 memories，情绪状态也会随之变化。Baseline vector 表示更慢变化的情感倾向；immediate vector 表示短期反应。

创建与删除行为¶

创建 entity relationship 会校验 source、target、scope、visibility、perspective 和 evidence。更新 evidence 会替换之前的 EVIDENCE_FOR links。显式删除会 detach 并删除 relationship node。

Emotion state 会按需要为 simulation character 创建。Emotion deltas 会创建带 turn、event 和 memory evidence 的 EmotionChangeAudit 节点，然后更新 state vector 和 version。

不变量¶

Relationship source 和 target 必须是不同实体。
Private relationships 需要 perspective_character_id。
private_description 需要 perspective character。
Interpersonal relationship detail 应连接 character endpoints。
Evidence memory ids 会去重。
Emotion audit evidence 必须被受影响角色记住，并由 simulation 中的 events 支持。
