The accepted reaction audit requires every upstream gate to pass before the final bit is set, so charge, baryon number, lepton families, energy, momentum, and threshold must all close in one chain. The final accepted bit is 1 because all three typed gates pass and every ledger balances exactly for the stated toy reaction model; real reaction measurements carry identification error, energy resolution, acceptance corrections, and statistical uncertainty.

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.

The audit cites conservation, energy, and threshold checks

The final audit is accepted only after 3 upstream gates are accepted.

All cited ledgers close together

The final accepted bit is 1 because scaled charge, baryon number, lepton families, energy, momentum, and threshold all close.
