What this proof establishes
Assuming the claims on the left, the claim on the right holds — checked by the archive's pipeline. Proof code is not displayed here.
Description
The explicit finite FAF error decays faster than 2^(-20ll*s). Acceptance above that target would therefore produce prover strategies exceeding the stated game threshold, contradicting game soundness.
