Function soft_core_realbist_source 

pub fn soft_core_realbist_source(iterations: u32) -> String

The CPU twin’s program: each iteration advances the LCG three times, mapping each output onto the realbist’s input ranges as it is drawn, runs the decision inline, and shows signed_order * 4 + order_side — the whole decision, side included, so the output stream classifies every decision as buy, sell, risk-blocked or no-trade.
