CydandClaude Fable 5 b772e716fe BT410 Phase 5.3.15: the electrical charge model -- real charge, closed feedback loop
The emitter charge cycle is now the authentic electrical model end to end.

- WIRE-VERIFIED resource fix: the Emitter block is graphicLength /
  dischargeTime / seekVoltage[5] (FRACTIONS of the generator's rated voltage,
  -1 sentinel) / seekVoltageRecommendedIndex. The old two-field guess read
  seekVoltage[3]=0.99 as "dischargeTime 0.99s" -- the true PPC discharge is
  0.2s, and the calibration reads seekV={6000,7000,8000,9900} x rated 10000,
  recommended gear 2: the documented curve exactly.
- Ctor calibration (@004bb120): energyTotal=(dmg+heat)x1e7; EC pins
  E=0.5V^2EC to energyTotal at the recommended gear; voltageScale calibrates
  the exponential charge to reach seekV[rec] in the authored RechargeRate
  seconds cold; damageFraction = the damage share.
- TrackSeekVoltage (@004ba838) + ChargeTimeScale (@004b0d50): the charge
  integrates from the generator through the heat-stretched time scale, and
  the I2R loss heats the GENERATOR -- verified GeneratorA at 477.9K charging
  its PPC (BT411 predicted ~+480K) while the avionics generator idles at 77.
  Hot generators charge slower: the heat/firepower feedback loop is CLOSED.
- Emitter::ComputeOutputVoltage override (now virtual, as in the binary
  vtable): dial = level/seekV[gear], 0.01 snap, over-1 clamp.
- Sub-stepped Loading (1/60s slices -- the BT411 weapon-brick fix) + the
  documented-divergence overcharge rescue. VERIFIED: the PPC loads at level
  ~7920, inside the binary's exact [7920,8080] snap window.
- FireWeapon energy algebra (@004bace8): damage/heat = energy shares x
  chargeRatio^2. VERIFIED dmg=11.78 / heat=1.079e8 at ratio 0.9906. The
  heatCost x 1e7 partial is retired -- heat now comes from the energy.

Zero Fail; jams/shutdowns regressions stay live under spam.
