Question

Finding

Holding4346→1406 fixed while converting only the9660 upper arm generates all three source totals12600/12740/13440. The generated heads14006/14146/14846 retain their existing status. This realizes the micro register family through retained macro components, not one whole-span conversion.

Reassessment

Consolidate the micro-to-Rounded bridge and decide which anchored routes best explain its placement.
