The confidence floor typed into the builder, as a number. A blank or non-numeric entry is NaN, so the spec
check reports it ("must be a number greater than 0 and less than 1, but is NaN") instead of the builder
guessing a value; an out-of-range number is kept as typed, for the same check to report.
