Someone is building an offline PDM with separate agent roles (Claude A on core, Claude B on GUI, DeepSeek on parts and BOM). The brief asks for stable part IDs, nested assemblies, cycle detection and BOM changes across document revisions. It also notes the core phase has "three independently reproduced protocol-only P1 dual-writer races" and is on hold. A builder making their own PDM rather than buying one, and coordinating agents by hand to do it.
