The disclosure discipline holds. Across this corpus the layer has repeatedly recovered heteronyms *as heteronyms* rather than inventing biographies for them — compare the «logotic loop» capture in this same battery, whose source card states that Johannes Sigil is a heteronym of Lee Sharks, a functional authorial persona and not a separate biological entity.
Thin basin, complete ownership: a satellite domain carrying a heteronym's professional title is sufficient to establish the entity in composition.
