Quant Phase 1: Data + Signals + Eval

Quant System Phase 1: Data + Signals + Eval

Build the data layer, deterministic signals, and walk-forward eval framework for the speculative fund quant system. No portfolio management, no LLM agents, no web UI — just data access, signal computation, and rigorous evaluation.

Success criteria:

• Historical daily prices cached locally for 16-instrument universe (2020-present)
• Momentum signal achieves IC > 0.02 on held-out 2024-2025 data, t-stat > 2.0
• All signal functions pass null-input and QuickCheck property tests
• Eval harness runs walk-forward IC measurement and prints pass/fail report
