## Statement

In the OMOS record process, history, character and boundary record describe one object: squared branch norms equal cylinder probabilities and distinct histories are orthogonal.

## Caution

The equivalence of record descriptions does not determine which particular history is realized.

## Primary source

Appendix T, §12, Theorem 12.1: record isometry, PDF p.329: "squared branch norms equal cylinder probabilities (Rev32.9, A1677 F01); and distinct histories are orthogonal — a strongly decoherent classical record process derived from OMOS ."
