The heat economy now bites back, verified under sustained fire: - Ballistic gate 1 (@4bbd36): destroyed-state or own-sink FailureHeat pins full recoil + the unavailable alarm (the NoAmmo roach-motel re-asserts). - CheckForJam (@4bbfcc): p = 0.41*T/failT clamped [minJamChance, 1.0], rolled per granted shot against the MUNGA uniform Random. Interim heat-degraded gate stands in for the deferred LiveFireEnabled novice switch (the exact spurious-cold-jam trap the BT411 port documented). VERIFIED: SRM6s jam at T~1200-1320 after riding past the authored 1000-degree threshold, and stay jammed (mission-reset recovery only) -- authentic. - Emitter hard gate (@4baab9): FailureHeat drops the beam state + charge each frame; SELF-RECOVERING once conduction cools the sink below failure. VERIFIED: the PPC settles into an emergent thermal duty cycle -- fire at ~1930K, spike to 2562K, shutdown, cool, refire -- firing exactly as fast as its sink sheds heat; the lasers oscillate around ~2200K. Zero Fail. Deferred: LiveFireEnabled/HeatModelOff experience gates, mech-disabled gate halves, coolant depletion, jam recovery via mission reset.

# HEAT.CPP / POWERSUB.CPP — the power/heat wave (Phase 5.3.10, 2026-07-21)
|
||
|
||
The mech's thermal + electrical economy is LIVE: weapons dump firing heat into
|
||
their own sinks, the sinks conduct through the Condenser bank into the central
|
||
HeatSink, temperatures drive the degradation/failure alarms, and every powered
|
||
subsystem tracks its generator through the electrical state machine.
|
||
|
||
## The heat topology (wire-verified on TEST.EGG)
|
||
|
||
`linkedSinkIndex` (the previously-missing HeatSink resource int — see below)
|
||
wires the authored conduction graph at construction:
|
||
|
||
weapons / equipment -> Condenser1..6 (slots 4-9) -> central HeatSink (slot 2)
|
||
GeneratorA..D (10-13) -> Condensers
|
||
Reservoir (3) -> central HeatSink
|
||
|
||
Authored values match the BT411 calibration audit EXACTLY: central bank mass
|
||
1.39e6, PPC's own sink 174000, thresholds 77 start / 1000 degradation / 2000
|
||
failure, PPC conductance 86800. (The central sink's own `linkedSinkIdx=5` is a
|
||
FORWARD reference — Condenser2 isn't constructed yet at slot 2's ctor — so its
|
||
drain is unwired; a post-walk fixup is a small future item. Everything drains
|
||
INTO it fine.)
|
||
|
||
## Reconstructed
|
||
|
||
- **HeatSink::HeatSinkSimulation** (@004ad924): absorb pendingHeat → T =
|
||
E/mass → UpdateHeatLoad (15-sample filter) → ConductHeat → alarm thresholds.
|
||
Installed by the HeatSink ctor (derived classes override and chain it).
|
||
- **ConductHeat / ComputeHeatFlow** (@004ad8ac/@004ad9ec): the two-body
|
||
equilibrium relaxation — `(T·massScale − (E_other+pending+E_own)/denom)·tau·
|
||
(1−exp(−dt·conductance·(coolant/capacity)·flowScale/denom))`. Verified:
|
||
flow == 0 exactly at uniform temperature; a fired PPC bleeds ~170K units/step
|
||
into Condenser4.
|
||
- **PoweredSubsystem ctor + PoweredSubsystemSimulation** (@004b0f74/@004b0bd0):
|
||
resolves `voltageSourceIndex` from the roster (GeneratorA-D — wire-verified),
|
||
attaches the tap (`Generator::TapVoltageSource`, −1 when full), and runs the
|
||
electrical FSM (Starting=0 / NoVoltage=1 / Shorted=2 / GeneratorOff=3 /
|
||
Ready=4) watching the generator state. Deferred: the AutoConnect
|
||
replacement-generator hunt (needs the status flags / damage wave).
|
||
- **Generator::GeneratorSimulation** (PARTIAL): heat step + start/short-recovery
|
||
timers; the load model (voltage sag, I²R self-heat feeding the charge
|
||
integration) joins the electrical-charge wave (TrackSeekVoltage).
|
||
- **Sensor::SensorSimulation** upgraded to the authentic gating (@004b1c4c):
|
||
power step first, radar = 1 − damage, electrical-Ready gate (badVoltage),
|
||
heat-state switch (Degradation ×0.5, Failure → 0). Verified: voltState=4,
|
||
radar 100% on the healthy mech.
|
||
- Weapons: Emitter/Projectile sims run the power step at their head; the
|
||
Loading recharge is gated on electrical Ready (authentic @4bbdf5); FireWeapon
|
||
dumps the firing heat.
|
||
|
||
## Heat units (1e7-native) — TWO authoring conventions
|
||
|
||
The heat chain is 1e7-unit-native (BT411 audit). The stream stores
|
||
`heatCostToFire` in TWO conventions:
|
||
- **Energy weapons: small units** (PPC = 11) — the ×1e7 comes from the energy
|
||
closed form ((1−dF)·E ≈ heatCost·1e7 at full charge). Our partial multiplies
|
||
by 1e7 pending the charge model.
|
||
- **Ballistics: native units** (SRM6 = 5.06e7) — dumped RAW. (Double-scaling
|
||
this to 5e14 was the runaway-temperature bug during bring-up.)
|
||
Both land ~+640K on the weapon's own sink — the consistent design magnitude.
|
||
|
||
## The resource-alignment resolution (wire-verified, closes the +3 mystery)
|
||
|
||
The raw-stream dumps pinned the FULL ancestry alignment:
|
||
- `HeatSink__SubsystemResource.linkedSinkIndex` — THE missing int that shifted
|
||
every descendant block +1 (PoweredSubsystem's voltageSourceIndex previously
|
||
read the linked-sink index — hence "power sources" appearing to be
|
||
Condensers).
|
||
- The MechWeapon pip tail is `pipPosition(int) + pipColor(3 floats) +
|
||
pipExtendedRange(int)` (+2) — matches BT411's verified overlay exactly.
|
||
- +1 +2 = the +3 the interim ProjectileWeapon pad compensated; the pad is gone.
|
||
- True bhk1 reads: PPC recharge **5.0 s** (not the misaligned 1.0), discharge
|
||
0.99 s, range 900, damage 12, heatCost 11, pipColor (0,0,1); SRM6 recharge
|
||
5 s, range 800, salvo damage 35, missileCount 6.
|
||
|
||
## VERIFIED (BT_FORCE_FIRE + BT_POWER_LOG)
|
||
|
||
PPC: 77° → fires → ~709° → relaxes to 441° across its 5 s reload → sustained
|
||
fire climbs the residual 441 → 674 → 838 → 960 — brushing the 1000° degradation
|
||
threshold: the authentic fire-discipline game. SRM salvos spike +641K and
|
||
cross degradation after three. Condensers absorb and pass to the central
|
||
bank. Neutral run: sensor Ready/100%, mech holds, zero Fail.
|
||
|
||
## Heat consequences (Phase 5.3.11, 2026-07-22)
|
||
|
||
The weapon-side consequences are wired and VERIFIED under sustained fire:
|
||
|
||
- **Ballistic gate 1** (@4bbd36): weapon destroyed-state or its own sink at
|
||
FailureHeat pins full recoil + the unavailable alarm (the NoAmmo roach-motel
|
||
re-asserts). (Mech-disabled half joins the damage wave.)
|
||
- **CheckForJam** (@4bbfcc): `p = 0.41·T/failT` clamped [minJamChance, 1.0],
|
||
rolled per granted shot against the MUNGA uniform `Random`. Interim gate:
|
||
heat-degraded only (stands in for the deferred `LiveFireEnabled` novice
|
||
switch AND the trivially-true `heatLoad>0` early-out — the exact spurious-
|
||
cold-jam trap the BT411 port documented). Verified: SRM6s jam at
|
||
T≈1200-1320 (24%+ rolls past the 1000° threshold), stay jammed.
|
||
- **Emitter hard gate** (@4baab9): FailureHeat drops the beam state + charge
|
||
each frame; SELF-RECOVERING — conduction cools the sink below 2000° and the
|
||
weapon resumes from Loading. Verified: the PPC settles into an emergent
|
||
thermal duty cycle (fire at ~1930° → spike 2562° → shutdown → cool → refire);
|
||
the lasers oscillate around ~2200°.
|
||
|
||
## Still deferred
|
||
|
||
UpdateCoolant / BalanceCoolant (coolant depletion + venting), the
|
||
HeatModelOff / LiveFireEnabled experience gates (novice mode), the electrical
|
||
charge model (TrackSeekVoltage / voltage sag / I²R), the mech-disabled halves
|
||
of the weapon gates (damage wave), the central sink's forward-linked drain,
|
||
Condenser MoveValve handling, jam recovery via ResetToInitialState (mission
|
||
reset path).
