记忆与主观断言¶

目的¶

Memories 和 claims 建模角色视角。MemoryAtom 节点存储带 keywords 和 embeddings 的紧凑回忆。SubjectiveEntityClaim 节点存储某个角色对另一个实体的看法，包括 confidence 和 evidence links。

重要属性¶

实体	重要属性
`MemoryAtom`	`id`, `summary`, `keywords`, `embedding`
`REMEMBERS` relationship	confidence, salience, behavioral relevance, stance metadata
`SubjectiveEntityClaim`	`id`, `simulation_id`, `observer_character_id`, `subject`, `category`, `statement`, `normalized_statement`, `stance`, `confidence`, supporting 和 contradicting memory ids, timestamps, `version`, `active`
`SubjectiveClaimChangeAudit`	`id`, `claim_id`, `simulation_id`, `turn_id`, `observer_character_id`, `change_type`, evidence memory ids, timestamps

关系¶

(:SubjectiveClaimChangeAudit)-[:CHANGED]->(:SubjectiveEntityClaim)

归属与生命周期¶

Memories 由 events 产生，然后附着到记住它们的 characters。一个 memory 可以被多个 characters 共享，但每条 REMEMBERS relationship 可以携带角色特定的 relevance。

Subjective claims 属于一个 simulation 和一个 observer character。它们从该 observer 的视角描述 subject entity，并会随着 simulator proposals 和 state commits 不断修订。

创建与删除行为¶

创建 memory 会用 SUPPORTS 把它连接到 event，并用 REMEMBERS 连接到一个或多个 characters。重新分配 memory characters 会替换现有 remembered links。删除 memory 会移除 memory node 和它的 evidence links。

创建 subjective claim 会校验 observer 属于 simulation，并校验 subject 在 simulation 或继承的 world graph 中可见。作为 turn 的一部分变更 claim 时，会创建 audit nodes。

不变量¶

Subjective claim observer 不能和 subject 是同一实体。
Supporting 和 contradicting memory ids 会去重，且不能重叠。
Claim 的 evidence memories 必须被 observer 记住。
normalized_statement 应足够稳定，以支持重复检测和矛盾检查。
当历史需要可解释性时，claims 可以变为 inactive，而不是物理删除。
