Pump performance: design vs. measured
Design head and efficiency curves rescaled to the live speed (affinity laws). The gap between the measured point and the expected point on the curve is the twin's evidence.

Live sensor values from the field payload (OPC 40223 names on hover).
Twin health: expected vs. actual
Computed from design data and live flow and speed. The same formulas run as PythonExpression functions in Maximo Monitor.
Vibration and temperature
Bars against the site alarm limits set in the twin file.
Active conditions
The rules from the twin file, also deployed as Monitor alert rules.

Failure mode library and fault injection
Each failure mode lists its symptoms in P-F order (earliest first). Injecting a failure mode ramps its severity in the physical model. The twin has to detect it from the sensor data alone.
