 219/-- RS explanation of galaxy rotation:
 220
 221    1. **Ledger shadows**: Dark matter is odd-phase ledger
 222    2. **Halo distribution**: J-cost equilibrium → ρ ∝ 1/r²
 223    3. **Flat curves**: M(r) ∝ r → v = constant
 224    4. **Cores**: Ledger interaction prevents cusp
 225    5. **Tully-Fisher**: Natural from J-cost -/

 235
 236/-- The derivation would be falsified if:
 237    1. Rotation curves not flat (already confirmed)
 238    2. No dark matter (MOND works everywhere)
 239    3. Ledger distribution doesn't match observations -/
