Oracle Verifier to Verifier run

SendClaim.oracleVerifier_toVerifier_run

Plain-language statement

The pure pass-through oracle verifier's underlying non-oracle verifier returns the statement together with the output oracle statements (input oracles at inl, the message at inr 0).

Exact Lean statement

theorem oracleVerifier_toVerifier_run {stmt : Statement} {oStmt : ∀ i, OStatement i}
    {tr : (pSpec Message).FullTranscript} :
    (oracleVerifier oSpec Statement OStatement Message).toVerifier.run ⟨stmt, oStmt⟩ tr =
      pure ⟨stmt, Sum.rec oStmt (fun i => match i with | 0 => tr 0)⟩

This lemma proves the final algebraic step in the DG25 Theorem 3.1 proof. It shows that if R > e + 1, then e * (R / (R - 1)) < e + 1. The intuition is that the fraction R / (R - 1) is always greater than 1, but as R gets larger, it gets closer to 1. The hypothesis R > e + 1 provides a strong enough bound to ensure the product e * (fraction) do...
