Root-caused the P2c abort with a cdb attach to the frozen abort dialog: the stack
was Gauge::Execute (GAUGE.cpp:598) -> abort, via GuardedExecute <- Update <-
ProcessOneActiveGauge. The engine base Gauge::Execute is Fail("not overridden")
-> abort, so an ACTIVE container that doesn't override Execute aborts by design;
GuardedExecute's SEH can't catch an abort(). The decode's "GeneratorCluster
overrides ONLY the dtor / renders via its children" was wrong -- the 1995 base
Gauge::Execute was a no-op, the 2007 WinTesla engine's aborts, so the container
MUST override Execute (the sibling SubsystemCluster does).
FIX: give GeneratorCluster the two container overrides (mirroring SubsystemCluster):
- BecameActive() -- blit the panel's static background pixmap (DrawPixelMap8) and,
by overriding the default, DON'T self-inactivate so the panel stays active.
- Execute() -- no-op (the 5 self-registered child gauges draw the dynamic content;
the override exists only to avoid the base Fail->abort).
Re-registered in BTL4MethodDescription[]. Verified DBASE+dev gauges: all 4
generator panels (A/B/C/D) render -- blue OutputVoltage bars (the @004c72ac
ScalarBarGauge Scalar* variant), labels, status lamps -- 0 "BecameActive not
defined" warnings, NO abort, combat un-regressed (TARGET DESTROYED). Phase 2 is
now COMPLETE (4/4 widgets: LeakGauge, VertNormalSlider, PilotList, GeneratorCluster).
