## Statement

Can the constituent-anchored charm bridge be matched to the MS-bar charm mass at its self-scale with an explicit conversion and scheme uncertainty?

## Caution

The constituent proxy and exact index normalization do not by themselves determine a scheme-matched charm mass.

## Primary source

Paper 2, §3.6, Missing constituent-to-MS conversion, PDF p.38: "the bridge is constituent- anchored and no constituent-to-MS conversion or scheme uncertainty is supplied;"
