Quant Bot v11 Ensemble Design — 6 Alphas, 9-Layer Kill Switch, Realistic Daily Target

Design note (not a trading recommendation) on a six-alpha portfolio for Binance perpetual futures, validated by six parallel domain experts (Mathematician, HFT/MM, Stat Arb, Risk, ML/RL, Event Alpha). Documents the post-mortem of a 5-day -$9.48 paper drain (Grid ping-pong inventory ledger gap), a recalibrated daily target of 0.6%-1.0% (not 1%+), a hard 5x leverage cap derived from 365-day ruin probability mathematics (5x=32%, 20x=98%, 50x=100%), and a 9-Layer Kill Switch covering order-rate, correlation, drawdown, latency, capital tier, stablecoin depeg, and funding spike axes. Authored under PAPER mode with no live capital deployed.
