"""
Test extremophile constraints against sample PDE solutions.

Validates that:
1. Pyrococcus rejects low-pressure solutions (requires 20-120 MPa)
2. Desulforudis rejects high-energy solutions (lives on 10^-15 W)
3. Orbital cavity rejects infinite Q (material damping limits)
4. Turing patterns reject infinite growth (nutrient limits)
5. Combined system correctly filters Navier-Stokes candidates
