Rounding moves an unquantifiable result above the reporting threshold.

Case contract

Return [Q or BELOW, value rounded to one decimal using ROUND_HALF_UP]. Q means exact value >= limit. Inputs are ordinary unsigned base-ten decimal strings without exponent notation, at most six fractional digits, and numeric values from zero through 1000000000000 inclusive. Inputs outside this bounded synthetic model are not supported.

Why this case matters

A deterministic synthetic laboratory reporting model isolates a software metadata contract; it is not a clinical procedure.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
rounds up to limit but remains below	`["Q", "6.0"]`	`["BELOW", "6.0"]`	Failed
