PIST-GCL Manifold Compression Algorithm v2.0
=============================================
Extracted from MATH_MODEL_MAP.tsv (~2634 equations) across domains:
- PIST Geometry: mass = t·(2k+1-t) — hyperbolic shell coordinate system
- Cognitive Load: L_I (entropy), L_E (BPB regret), homeostatic control
- Delta GCL: delta-encoding + PTOS dictionary + VLE + Huffman
- Thermodynamic: Landauer limit, dS/dt ≤ 0 verification
- GWL Rotational Coupling: weight_ij = cos(Δθ)cos(Δφ)(1-2|Δχ|)e^{-|Δp|²/2σ²}
- KDA Physics: Pressure P(i)=P₀·χ^i, Hugoniot T_peak = T₀·(P_peak/P₀)^0.65
- Bracket Braid: phase accumulation, gradient alignment
- Phonon Graph: F(i,j)=e^{-d/127}cos(2πd/127)
Architecture (4-layer manifold pipeline):
Layer 0: PIST Remap — bytes → (shell, offset, mass) coordinates
Filter grounded (mass=0) bytes, RLE zero-mass runs
Layer 1: Cognitive Route — BPB-aware routing with homeostatic canal
Route high-mass "seismic" bytes, skip/drop low-mass bytes
Layer 2: Delta + PTOS + VLE + Huffman
Variable-length delta packing (1-3 bytes per coord)
PTOS 4-byte dictionary lookup, Huffman backend
Layer 3: Thermodynamic Verify — dS/dt ≤ 0, Landauer bound ≥ work
