The capstone joins conservation, energy-momentum, and threshold gates. 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 cites conservation, energy, and threshold checks
The final audit is accepted only after 3 upstream gates are accepted.
3 accepted gates
All cited ledgers close together
The final accepted bit is 1 because scaled charge, baryon number, lepton families, energy, momentum, and threshold all close.
