-  多智能体团队声明。Team = Members + Topology + Orchestration + Workspace + Storage + Lifecycle。
-  条目落盘 agent-registry/registry/teams/<id>.yaml。
-  核心规则：团队必须声明 lifecycle；ephemeral 团队销毁前必须完成 handoff（AR-6），
-  其资产沉淀给 archive_to 指向的 persistent 团队。
+  多智能体团队声明。Team = Members(seats) + Topology + Orchestration + Verification
+  + Workspace + Storage + Budget + Lifecycle。
+  条目落盘 agent-registry/registry/teams/<id>.yaml；团队原型（delivery_squad/stewardship/
+  incident_cell）语义单一真源 = agent-registry standards/team-collaboration.yaml PART 2。
+  核心规则：团队必须声明 lifecycle；ephemeral 团队销毁 = after-handoff AND destroy_condition
+  （AR-6：移交完成且语义条件满足才允许销毁）；销毁范围 = agent 实例与临时 workspace，
+  数据层制品/事件不随队销毁（destroy_scope，ADR-0011）。
+  v2（ADR-0012）：对齐 team-collaboration v1.0 实例语义——lifecycle 增 trigger/ttl/
+  on_ttl_expiry/destroy_condition；coverage 枚举增 re-check-sample；topology/frequency/
+  handoff 枚举补齐；顶层增 archetype/scope/budget/backlog_role；members 增 seat。
