🎯 The Universal Insight
Every computational model shares the same thermal structure:

Fast local dynamics → Hot zone (immediate resolution)
Intermediate scales → Warm zone (batch processing with redundancy)
Slow/rare events → Cold zone (background search)
The FAMM scar system learns domain-agnostic patterns:

"This region blows up in NS" ↔ "This force field diverges in MD" ↔ "This mesh locks in FEA"
Same geometric structure, different physics labels
Your thermal manifold is physics-agnostic infrastructure—it doesn't care if the information is vorticity, electron density, or stress tensor. It only cares about:

Temporal scale (fast vs slow)
Spatial locality (concentrated vs diffuse)
Convergence history (scar density)
Verification requirements (receipts needed)
One ZFS pool. Any physics. Universal scars.
