fault-free
Entirely without blemish
Fault-free means without defects or errors.
The term appears most often in technical contexts—fault-free software, fault-free manufacturing—where even small flaws matter.
It can also describe performance: a fault-free routine in gymnastics.
The compound emphasizes complete absence of problems rather than mere adequacy.
