 200/-! ## Alternative Theories -/
 201
 202/-- Other approaches to the Λ problem:
 203
 204    1. **Anthropic**: We observe small Λ because large Λ prevents life
 205    2. **Quintessence**: Dynamic dark energy field
 206    3. **Modified gravity**: f(R), MOND extensions
 207    4. **Holographic**: Λ from holographic bound
 208    5. **RS**: φ-ladder cancellation (this work)
 209
 210    RS is unique in providing a calculable mechanism. -/

 219/-! ## Falsification Criteria -/
 220
 221/-- The derivation would be falsified if:
 222    1. w ≠ -1 definitively measured
 223    2. Λ varies with time
