[ HOW THE CASE READS ]
From Input To Public Evidence.
The application stores structured evidence. The public page turns it into a readable pictogram case history.
01
Submitted Context
Framework output for the Designers Italia Icons Mail icon in the default style.
02
Primary Finding
Evidence trend review: Public evidence trend has no visible historical evidence source, so it cannot render as a sourced public trend.
03
Metric Reading
Primary referent: it mail.
04
Public Recommendation
Review annual evidence before publishing trend or cohort-transfer claims.

[ 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
The pictogram works with labels or context.
Pair it with text and monitor interpretation.
0.50-0.64
Needs intervention
Current report
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.

| Temporal Convergence | 0.45 | How strongly meaning persists over time without semantic decay. |
| Neurocognitive Convergence | 0.48 | How strongly the symbol follows AAC pictogram reading: transparent referent, concrete action, low convention load, and support. |
| Context Independence | 0.59 | How strongly meaning survives without external labels or placement cues. |
| Collective Resonance | 0.51 | How strongly public evidence supports shared recognition and persistence. |

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Review annual evidence before publishing trend or cohort-transfer claims.
Action
Run representative user testing before publication.
Action
Keep the text label visible until semantic transparency is proven.
Action
Keep visible label support when scores sit below strong clarity.
Action
Validate interpretation with representative users before high-risk release.
[ Private testing / Admin invite ]
