Heteronymy as Ethical Operation Against Civil-Name Reduction completes the initial Semantic Economy triad: bearing is ontological, provenance debt economic, and heteronymy ethical.
A pseudonym changes the name attached to an authorial function. A heteronym changes the organization of the function itself. The paper proposes eight markers: stable voice, distinct commitments, bounded corpus, recurring methods, capacity for disagreement, distinct position, continuity, and declared substrate provenance.
The ethical center is accountable irreducibility. A civil bearer may remain legally and editorially responsible without becoming the exhaustive source of every authorial function. Heteronymy neither conceals responsibility nor invents independent civil persons.
Four conditions separate ethical heteronymy from deception: provenance must be declared; no false independence may be claimed; legal responsibility may not be evaded; and the authorial function must be genuinely distinct.
The Caesar/God scene becomes a structural figure. The attribution regime may legitimately demand a name, custody, and rights administration. It is not thereby owed the reduction of all plurality to that civic surface.
The Dodecad, MANUS, Assembly witness offices, Mary Lee, and philological transmissions become test cases and boundary cases. The architecture does not prevent civil-name collapse; it makes the reduction legible as loss rather than discovery of ground truth.
