The eng-page generator-voltage bar (evolt.pcc, ScalarBarGauge @004c721c) and
the MyomerCluster seek-voltage graph were fed by GeneratorVoltageConnection,
which walked the same dead path as the generator-letter lamp:
ResolveLink(AttributePointerOf(subsystem,"InputVoltage")) -> read resolved
+0x1DC == Generator::outputVoltage. The BT_DEV_GAUGES audio attribute rows
shifted the chained attribute ids so AttributePointerOf no longer lands on
voltageSource@0x1D0 -> the bar always read 0.
New BTGeneratorVoltage(subsystem) bridge (powersub.cpp) reads the NAMED member
via PoweredSubsystem::ResolveVoltageSource()->Generator::MeasuredVoltage()
(outputVoltage@0x1DC), bypassing the attribute table -- same pattern as
BTPowerSourceFrame/BTCoolingLoopFrame. Both GeneratorVoltageConnection callers
(the ScalarBarGauge param + the MyomerCluster seekValue) now pass subsystem_in.
[voltfeed]-verified: Myomers -> 10000V from GeneratorD (was 0 on the dead
path). Both pod + glass builds clean. Eng-page render awaiting live playtest.
