Scoping question
Can a flex product be auditably fair to the consumer and viable for the supplier — before any customer is enrolled or the grid is touched?
Method
Backtest candidate tariffs on synthetic cohorts; deterministic core decides fairness, AI assists exploration only; shadow-mode throughout — the grid is never touched.
Flex Nexus · Lane B
Design and backtest flex products before you build them.
Prove to regulators they're auditably fair. Model how things could have been. Test the market rules before they're locked in — on real deterministic engines, empowered with AI at the fringe, on open data. indicative · synthetic cohort
