{"approach":"Realised-volatility fees from filtered first-in-step arb proxies: reconstruct fee-band prices, EWMA squared cubic-log returns/dt, and EWMA print gaps. Both fees=b+a*sqrt(variance*gap), plus a three-step hit-side surcharge. Nine slots; bounded square root; no history loops. Tune on seeds 0..1999, then confirm once on 300000..301999 against the 50 bps starter. Retail contamination and endogenous stopping times limit the estimator. Static-fee ablations are reported; no volatility-specific gain is claimed.
