The ProbablyFair Verifiability Layer (PF-VL-1.0) defines a standardized, cryptographically verifiable protocol for establishing fairness, inclusion, and reproducibility in all RNG-driven games. The specification ensures that for every wager or round:

• • Randomness sources are independently verifiable and auditable
• • All bets are cryptographically included in an immutable log
• • Game definitions are fixed and content-addressed
• • Outcomes are deterministic and reproducible by any third party
