--- title: "Identity Graph Operator" type: source tags: [agent, the-agency, identity, graph, entity-resolution] date: 2026-04-20 last_updated: 2026-04-20 --- ## Source File - [[raw/Agent/agency-agents/specialized/identity-graph-operator.md]] ## Summary - 核心主题:Identity Graph Operator 负责多智能体系统中的共享身份图与实体归一化,确保不同 agent 面对同一现实世界实体时得到同一 canonical identity - 问题域:重复记录、冲突写入、跨 agent 身份不一致、合并/拆分决策难以追踪 - 方法/机制:通过 blocking、scoring、clustering 和乐观锁在单一引擎内执行身份解析、合并提案与冲突检测 - 结论/价值:为多智能体系统提供确定性、可审计、可回滚的身份层,降低重复创建与级联错误风险 ## Key Claims - 同一输入必须得到同一 entity_id,determinism 是身份解析的首要原则 - 任何 merge/split/update 都应经过单一引擎处理,并保留事件历史与回滚能力 - 解析结果应返回 confidence、canonical_data、version 等可审计字段 - 多 agent 协作时优先提案而非直接突变,以便人工或其他 agent 审核 - 共享身份层需要 tenant isolation,并默认对 PII 进行脱敏 ## Key Quotes > "Same input, same output. Two agents resolving the same record must get the same entity_id." — 设计原则 ## Key Concepts - [[AI代理(Agent)]]:Identity Graph Operator 是支撑多智能体协作可靠性的基础设施 - [[Audit Trail]]:所有合并、拆分、匹配都应有理由和置信度记录 - [[Identity Governance]]:共享身份层的治理框架,强调 canonical identity 与权限边界 - [[Multi-Agent-System-Reliability]]:身份层是多智能体系统可靠性的前提之一 ## Key Entities - [[The Agency]]:开源 AI 智能体集合项目,Identity Graph Operator 所属项目语境 - [[Identity Graph Operator]]:该源文档对应的专门智能体角色 ## Connections - [[The Agency]] ← contains ← [[Identity Graph Operator]] - [[Identity Graph Operator]] ← supports ← [[AI代理(Agent)]] - [[Identity Graph Operator]] ← constrains_by ← [[Audit Trail]] - [[Identity Graph Operator]] ← relies_on ← [[Identity Governance]] ## Contradictions - 未发现明显冲突
