Generate a sealed FINANCEGPT SYNTHETIC option chain from a promoted LQM

Uses a human-promoted derivatives-surface LQM plus a typed numeric conditioning envelope to generate a synthetic implied-volatility surface. FinanceGPT applies deterministic static no-arbitrage validation and repair before deriving option prices and Greeks. Outputs are explicitly synthetic, non-observed and never execution eligible or a substitute for observed market data.
