[SESSION OPPORTUNITY CAPACITY BOUNDS]
Pre-Execution Neural Gating, Online Backpropagation & Counterfactual Drawdown DefenseFrontier quantitative architecture replacing directional forecasting with pre-execution session capacity bounds. Evaluated across 12,057 closed counterfactual setups with 7,322R of unforced drawdown defended, the system projects real-time volatility exhaustion and order flow imbalance onto an online neural gating tensor with daily settlement backpropagation, proving the mathematical value of algorithmic inaction.
