Neutral Substrate

This result establishes an impossibility theorem:

Any representational substrate that remains stable
under incompatible extensions must be pre-causal and pre-normative.

The result constrains what may appear at the foundational layer of any ontology intended to function as a shared substrate across persistent disagreement.

Artifacts

• Formal proof (Lean 4)
• Narrative exposition (Paper 100)

Implication

Embedding causal models, values, obligations, or policy judgments at the substrate level entails a loss of neutrality or extension stability.

Such commitments therefore cannot be present at the foundational layer of a substrate intended to remain stable under persistent disagreement.
