Substrate Incompleteness Haunts Every Fairness Mechanism

Substrate incompleteness: any fairness mechanism misses exploitable cases — its "capture surface." Adding mechanisms closes some gaps, opens others; progress is non-monotonic. Parallels Gödel's theorems. VibeSwap names five surfaces: v(S) estimation gaps, unmeasured contributions, off-chain coalitions, value-function mismatch, ETM-blindness. Projects claiming "eliminates MEV" hide asterisks. Naming surfaces builds trust, not weakness.
