Spatial Reconstruction Cross Scans

Trigger Mask Decision Three-Row Scan

enabled, masked, vetoed

Enabled, masked, and vetoed candidates close the trigger bit. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

Enabled candidate passes without veto

Candidate channel 2 has enabled bit 1 and veto bit 0, so accepted bit is 1.
