Context & evidence · data confidence A: 105 price reads over 137 days · 15 supply reads · volatility measured · volatility tier Jumpy. ETB signals run the full sealed stack (upgraded 2026-07-10): supply+price core, NEW maturity gate, market-relative strength, and retail-price anchor. The set÷box ratio and Rip Score stay excluded — they don’t translate to a 9-pack product. Every run is logged to the ETB Signal Log so the backtest can grade these dials.
