AmmoBin::AttributeIndex was a bare, default-constructed static with NO parent chain, so nothing resolved on an AmmoBin -- even the inherited SimulationState came back NULL (the audio AmmoState + SimulationState watchers were skipped). - Chain AmmoBin::AttributeIndex to HeatWatcher::GetAttributeIndex() and give it a real AttributePointers[] with AmmoState -> ammoAlarm (@0x194, the 6-level 0x54 StateIndicator-compatible feed alarm, already SetLevel'd Feeding/Loaded/Empty/ Dumped by the sim) so reload/empty/feed audio fires on the ammo transition. With this every StateIndicator audio attribute across the mech + all subsystems binds to a real indicator: audiostate skips 85 -> 0. Remaining audio gaps are the inert Logical/Scalar/Enum subsystem attrs (ReportLeak/GeneratorOn/ConfigureActive Press/MotionState/SpeedOfTorsoHorizontal/TargetRangeExponent), which read 0 (silent, non-crashing) pending backing members in their size-locked layouts.

|
// SharedData connection (launcher this[0x10F]@0x43C, connection ctor @4bcbb0,
