超越同步：联合音乐制作中的可审计性与伙伴差异化合作，以身体打击乐为例

The author proposes a complementary mechanism with a deliberately minimal core: coordinated music-making makes each participant's contribution auditable , generating person-specific information about demonstrated reliability, and this information subsequently produces partner-differentiated cooperation. Auditability differs from generic observability in that contributions are evaluat
