Subject: [PATCH] seek-4 verification harness (BT_FORCE_SEEK) + the full
 supercharge/overheat arc measured live

BT_FORCE_SEEK=<idx> pins the seek gear in MyomersSimulation (env-gated
bench; the eng-page toggle stays the authentic path) -- the supercharge
loop was unreachable on a headless rig.

Measured (Black Hawk, WALLTEST, full autodrive at gear 4):
- cold: drive=1.42843 (exactly 0.9999/0.7), demand 87.85, actual run
  speed 53.7 u/s = 193 kph -- SUPERCHARGE (Oracle's pod figure: 182 for
  a 75-tonner; the 60t Black Hawk runs faster);
- heat at ratio^2 = 2.04: myomer T 531 -> 1765 (deep past the 1000
  degradation line);
- heatFactor governor: drive 1.43 -> 1.10 -> 0.62 (the supercharged mech
  slows BELOW normal while cooked), coolant pulls T back (1765 -> 740),
  drive recovers to ~0.77, oscillates -- the mech self-settles into a
  thermally-limited cruise: 'top speed for less than a minute' exactly;
- the hard freeze (drive -> 0: demand AND turn zeroed) is the same code
  path past failure temp, reachable when the coolant loop is compromised.
