## Statement

The earlier depth-exclusion cut treated commutation of the mass and electromagnetic charge operators as forbidding depth sourcing.

## Caution

Withdrawing the cut does not identify the two clock labels or select depth or order as the physical source.

## Primary source

Appendix S, §7, Casualty #7: depth-exclusion cut, PDF p.307: "the depth-exclusion cut retired ([M, Qem ] = 0 forbids identifying the two Z4 labels but not depth sourcing)."
