[ SCORE SCALE ]
The Public Verdict Has A Range.
The level explains the estimated context. It is not a certification.
0.80-1.00
Strong clarity
The pictogram communicates well in this context.
Use it, then keep testing with real users.
0.65-0.79
Usable with support
Current report
The pictogram works with labels or context.
Pair it with text and monitor interpretation.
0.50-0.64
Needs intervention
The pictogram carries meaningful clarity risk.
Improve the symbol before relying on it.
0.00-0.49
Not reliable
The pictogram does not communicate enough alone.
Replace it or add strong alternative support.
[ CONVERGENCE PROFILE ]
Where Meaning Converges.
The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It describes estimated convergence, not universal validity.
Convergent meaning profile
The radar shows where meaning converges. It does not certify universal validity.
