232
233/-- RS picture of phase transitions:
234
235 1. **J-cost landscape**: Multi-dimensional surface
236 2. **Minima**: Phases are local minima
237 3. **First order**: Jump between separated minima
238 4. **Second order**: Minima merge, fluctuations diverge
239 5. **Critical point**: Topology change
240 6. **Nucleation**: Thermal crossing of barriers -/
241def summary : List String := [
242 "Phases = J-cost minima",
243 "First order = jump between minima",
244 "Second order = merging minima",
245 "Critical = topology change",

249/-! ## Falsification Criteria -/
250
251/-- The derivation would be falsified if:
252 1. Phase transitions have no J-cost interpretation
253 2. Critical behavior contradicts J-cost predictions
254 3. Nucleation doesn't follow J-cost barriers -/
