StatusFlow gains parentStatusFlowId (recursive FK) enabling nested / hierarchical state machines (HSM). StatusFlowTransition gains toStatusFlowId PK field for cross-flow transitions. New StatusFlowStack entity (create-only, cache="never") tracks the FSM execution stack per entity/pk pair. NOTE: StatusFlowTransition PK change requires DB migration for existing deployments with data in STATUS_FLOW_TRANSITION (low risk — configuration data reloaded on startup). UnitData.xml additions: Acceleration, Jerk, Snap, Angle, Angular Velocity/Acceleration, Volumetric and Mass Flow, Sound Level, Electrical (charge, capacitance, inductance), Viscosity, Force, Torque — covering common industrial and IoT measurement types.

Summary
Two independent additions to the data model:
1. Hierarchical StatusFlow (HSM)
Adds support for nested state machines by extending the
StatusFlowentity:StatusFlow.parentStatusFlowId— self-referential FK, allows a flow to be a sub-flow of anotherStatusFlowStackentity — tracks the active sub-flow stack per record, enabling hierarchical state navigation (enter sub-flow, exit back to parent on completion)StatusFlowTransitionPK change: addstoStatusFlowIdto support transitions that enter a sub-flowUseful for complex domain objects (equipment lifecycle, multi-stage orders) where a top-level state contains an independent sub-machine.
2. Physics and engineering units of measure
Extends the
UomTypeandUomseed data with standard physical and engineering dimensions:These complement the existing length/mass/time UoMs already in the framework.
