BT410 Phase 5.3.11: weapon heat consequences -- jams + thermal shutdowns LIVE

Browse Source 
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 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°.
