Superseded: Lean 4 formalization of the contextual structural explainability layer.

Lean 4 formalization of Accountable Entities (AE): six named entity kinds and their mapping to six identity regimes.

Superseded: Lean 4 formalization of the Ontological Neutrality Theorem

Paper establishing that for an ontological substrate to remain neutral and stable under allowable frameworks that include persistent disagreement, causal or normative commitments cannot be part of the substrate itself.

Superseded: Lean 4 formalization of the necessary and sufficient identity-and-persistence regimes for neutral accountability substrates.

This paper derives necessary and sufficient structural constraints on neutral ontological substrates required to support stable reference and accountability under persistent disagreement.
