    now passes `subsystem_in` (not the `InputVoltage` attribute slot). **Lesson: gauge value feeds
    must read named members through a complete-type bridge, NOT `AttributePointerOf`+`ResolveLink`
    — the attribute table's chained ids are unstable under the audio rows.** The eng-page
-   `GeneratorVoltageConnection` (evolt voltage bar, btl4gau2.cpp:1737) still uses the same
-   `AttributePointerOf("InputVoltage")` path and is the remaining sibling to convert.
+   generator-voltage bar + MyomerCluster seek-voltage graph (`GeneratorVoltageConnection`,
+   evolt.pcc, btl4gau2.cpp:806/1750) were on the same dead path and are now converted the same
+   way -> `BTGeneratorVoltage(subsystem)` reads `Generator::MeasuredVoltage()`
+   (outputVoltage@0x1DC); `[voltfeed]`-verified (Myomers -> 10000V from GeneratorD). Still on the
+   OLD path but NOT yet converted (different attribute, direct read, not confirmed broken): the
+   GeneratorCluster + EnergyWeaponCluster bars that read `AttributePointerOf(subsystem,
+   "OutputVoltage")` directly (btl4gau2.cpp:968, ~1920).
 Diagnostics retained (env `BT_LOOP_LOG`): `[loopfeed]` (BTCoolingLoopFrame) + `[busfeed]`
-(BTPowerSourceFrame) print each lamp's resolved frame + source.
+(BTPowerSourceFrame) + `[voltfeed]` (BTGeneratorVoltage) print each widget's resolved value + source.
 **HUMAN-VERIFIED live 2026-07-21** (pod build, solo ARENA1 cockpit): the loop number + generator
 letter boxes render correctly on the weapon panels.
