+    "description": "Valid ISO date literals directly compared with trade_date, current_date, date, decision_date or execution_date compile to the numeric bytecode VM as YYYYMMDD keys. All other strings remain on the Rhai path. Numeric VM floating comparisons now match Rhai relative epsilon semantics."
