Complete model of the co-evolution loop:
1. DAG finds basin → checkpoint
2. FAMM stores checkpoint (delay-line memory with frustration)
3. FSDU computes scar (residual manifold geometry)
4. Scar transforms coordinates (Fisher eigenstructure rotation)
5. DNA re-encodes in new coordinates (alphabet evolves)
6. Sort accelerates search (lexicographic = energy order)
7. Results feedback as new scars (loop closes)
All four systems (DAG, FAMM, FSDU, DNA) are coupled.
None can be understood in isolation.
