The naming problem
A diagnosis can make a pattern legible while overclaiming what the pattern is. The corpus applies the same suspicion to genres, institutional classifications, persona names and statistics. This is one useful connection to Lines Imposed Upon Fields, but that page is no longer treated as a master theory of personhood.
Plural personhood is not a clinical inference
Plural Personhood / The Non-Unitary Self records a literal philosophical/ontological proposition: the self does not resolve to a unitary entity. The wiki does not derive that claim from diagnosis, nor use the claim to diagnose the author or any character.
Clinical name / artistic name
Apophoenix, Cagliostro, fictional conditions, personae and pseudo-technical terms are acts of naming, but they are not therefore medical diagnoses. The category of “person” itself can also be under pressure without every disturbance of personhood becoming pathology.
The wiki’s own danger
An encyclopedia is unusually tempted to turn provisional labels into final identity. For that reason legal/biographical identity, narrator, persona, fictional character, diagnosis, self-description and author-confirmed ontology remain separate relation types.
