An enabled candidate with no veto is accepted. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

An enabled candidate can pass the mask

The detector has 8 channels, with 6 enabled. The candidate channel is enabled.

No veto leaves the accepted bit on

Candidate enabled is 1, veto is 0, so accepted is 1.
