A final role-only audit cites each checked signal source. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The audit page shows roles, not repeated numbers
The final audit cites the sample, bin, alias, averaging, and lock-in sources without restating their numeric labels.

Every cited source must match its checked value
The audit accepted bit is 1 only because every source reference matches the source check.
