## Statement

Under the explicit B-map and compact field dictionary, the one-generation quark and lepton placements and all sixteen hypercharges are fixed.

## Caution

This one-generation dictionary does not select the compact gauge boundary or construct the explicit three-generation embedding.

## Primary source

Paper 1, §6, Status under the explicit B-map, PDF p.29: "Status under B: all one-generation quark and lepton placements and all sixteen hypercharges are PROVED under the explicit B-map (A689)."
