[ CONVERGENCE PROFILE ]
The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It shows agreement between signals, not universal validity.
The radar shows where meaning converges. It does not certify universal validity.

How strongly visual form survives size, blur, contrast, and detail loss.
| Axis | Score | Description |

| Perceptual Convergence | 0.75 | How strongly visual form survives size, blur, contrast, and detail loss. |
| Semantic Convergence | 0.60 | How strongly extracted meaning converges on one interpretation. |
| Functional Convergence | 0.61 | How strongly the symbol maps to the intended function. |
| Cultural Convergence | 0.47 | How strongly recognition holds across cultural evidence and assumptions. |
| Temporal Convergence | 0.56 | How strongly meaning persists over time without semantic decay. |
| Neurocognitive Convergence | 0.64 | How strongly the symbol follows AAC pictogram reading: transparent referent, concrete action, low convention load, and support. |
| Context Independence | 0.63 | How strongly meaning survives without external labels or placement cues. |
| Collective Resonance | 0.46 | How strongly public evidence supports shared recognition and persistence. |
Cultural axis
0.47
Recognition depends on cultural exposure and prior assumptions, so shared understanding is weaker than visual recognition alone suggests.
Evidence floor
0.43
Public evidence is thin or unavailable for display, so the cultural reading stays cautious.
