FINAI 2.0 — an ultra-low-latency predictive ML layer for markets. Feature engineering → training → strict no-look-ahead sim → inference, in Rust/C++ at 4–50 µs/tick, enabling tick-level backtesting. Per-bar signals (probabilities + raw) across tickers & timeframes, asset-agnostic, strictly causal. Transparent by design: live public board + immutable S3 audit trail — every signal timestamped, independently verifiable. For market makers, execution desks & systematic funds.
