The final ultrasound report is accepted only by cited source checks. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

The audit cites each source ledger

Depth 12 meters, reflection ratio 1 over 2, resolution limit 4 meters, and shift 4 hertz are all source-bound.

The accepted bit requires every source gate

The final report is accepted only because the range gate is active, the resolution gate passes, and every cited value matches its source.
