The final audit accepts only one coherent source chain. 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 final audit cites every upstream check

The audited gap is 4 joules, the photon matched bit is 1, and the selection allowed bit is 1.

Acceptance requires the line list and resolution to agree

The series count is 3, the calibrated channel is 9, the resolved bit is 1, and the final accepted bit is 1.
