How A04 is structured

terminal codes, selectable in a device record

branch headings, not selectable

name a specific device type

67%

fallback entries: Other and Accessories

The Solution Filters branch runs 3 levels deep. 2 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 6 codes marked terminal.

3 terminal codes are “- Other” entries and 1 is an “- Accessories” entry, 67% 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.
