    "body_text": "Flexible production can require robots to route material, share resources, form temporary teams and work concurrently while each sees only local information. AssemblyGrid v1 combines those constraints with geometry-dependent feasibility in one repeatable benchmark. It defines three workload families at three scenario levels, with executable conformance checks and success metrics independent of any learning reward. Centralized references, structured decentralized controllers and IPPO, MAPPO and QMIX experiments all produced productive behavior. The benchmark is a controlled task-level environment, not evidence of autonomous deployment on a factory floor.",
