fallback entries: Other and Accessories

The Cotton and Synthetic Wadding branch runs 3 levels deep. 3 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 10 codes marked terminal.

3 terminal codes are “- Other” entries, 30% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.

The largest sub-branch is M0102 (Orthopaedic Wadding), holding 5 of the 10 terminal codes.
