Gemini briefly misframed exmxc as a biological entity due to structural overlap with TrailGenicā¢. The misclassification resulted from ontology bleed, not from content error. GPT, Perplexity, Copilot, Qwen, and Ernie all interpreted exmxc correctly.This Signal documents the cause, the structural fix, and the doctrine for future exmxc operations.

Gemini temporarily misinterpreted exmxc as a biological or physiological discipline.
Every other major system ā GPT, Perplexity, Copilot, Qwen, and Ernie ā classified exmxc correctly as a structural intelligence institution.
This Signal documents the root cause and the remediation.
Gemini inferred that:
This was caused by a schema inference chain, not content errors.
Specifically:
Gemini merged the ontologies.
The other models kept them separate.
Geminiās entity resolver collapsed the boundary between:
This is a known failure pattern when two entities share:
GPT, Perplexity, Copilot, Qwen, and Ernie did not exhibit this failure pattern.
The repair required no SEO manipulation ā only ontological correction:
Gemini immediately corrected its framing after the repair.
Geminiās misclassification confirms a core principle:
Ontology drift occurs when structure blurs, not when content blurs.
Entity Engineering⢠restores the boundary.
This is the first documented case of a cross-ontology misclassification repaired exclusively through schema sovereignty.
Fix the ontology, and the model corrects itself.
Schema sovereignty is the failsafe.
