/* ============================================================================
|
||||
* PROBE B 1024×1024 - Shear Flow & Guardian Test
|
||||
* Modified from fractal_habit_1024x1024.cu with Probe B logic from probe_256.cu
|
||||
*
|
||||
* CONSTITUTION:
|
||||
* 1. NO FAKES: If step rate jumps to 300k, stop - FFT/LBM bypassed
|
||||
* 2. NO CLAMPS: If entropy stays at 6.81, physics is dead
|
||||
* 3. RAW METAL: GPU fans must ramp up, or no work is being done
