Research compilation
Research compilation from a published ICIT-style digitization — not a complete or licensed photographic corpus
Fit on current defined metric: weak.
A necessary null against linguistic claims; currently a weaker global fit.
Assumptions
- Order is decorative or conventional rather than grammatical
Strengths
- Would explain the lack of long texts
- Emblem systems exist in other cultures
Limitations
- Directionality and rigid templates look more structured than pure emblems
- Does not explain n-gram retention well
