## Statement

The ribbon full-twist identity leaves the registered connected Markov second moment strictly positive at n = 8,9,10, excluding exact switch-off there.

## Caution

Nonzero later moments do not settle the finite support-threshold test, whose energy coefficient remains open.

## Primary source

Paper 9, §9, Ribbon full-twist obstruction, PDF p.136: "full-twist identity also excludes exact switch-off (Ωn > 0 at n = 8, 9, 10)."
