Abstract

NSCOSv3 Smile — ProofEnv (Heston-style variance: mean reversion, spreads).

This paper presents 62 machine-verified theorems. All results are formally verified in the Lean 4 (63 verification units, 62 proved statements) and exportable to Lean 4.

Novelty

No discernible novelty — the paper is an auto-generated skeleton listing 62 formally verified but mathematically elementary lemmas (nonnegativity, sign conditions, basic inequalities) about Heston-style stochastic volatility, with no proofs, exposition, or intellectual narrative.
