Opening gamma-ladder selection of defined-risk SPXW credit verticals

Validated opening gamma-ladder geometry may select a one-lot SPXW 0DTE put credit vertical, call credit vertical, or abstention with incremental calibrated predictive skill and positive net untouched-holdout expectancy beyond option-implied, volatility, price, liquidity, scalar-GEX, calendar/event, and matched-placebo controls; attraction, barrier, and null maps compete equally.
