Defines neutral constraints under which explainability is possible without embedding interpretation.
Structural Explainability defines the minimal, stable constraints under which identity, structure, change, explanation, and persistent disagreement can coexist over time without embedding interpretation.
It characterizes the representational conditions required for explainability to remain possible across incompatible legal, political, scientific, or normative frameworks.
This organization contains specifications, formalizations, and papers that define, justify, and defend that neutral space.
This organization is structured around roles:
| Role | Purpose |
|---|---|
| Specifications | Define what must be true for admissibility |
| Formalizations | Demonstrate that specifications are internally consistent |
| Foundations | Establish the underlying theoretical results |
| Papers | Justify why the constraints are necessary and unavoidable |
| Boundaries & Overlays | Define how interpretation may attach without entering the substrate |
These repositories define the admissible representational space for structurally explainable systems. They are normative only in the sense of defining constraints, not interpretations.
| Repository | Purpose | Status |
|---|---|---|
| spec-se | Neutrality and boundary constraints of Structural Explainability | Normative |
| spec-ae | Accountable Entities and identity regimes | Normative |
| spec-ep | Graph evolution over accountable entities | Normative |
| spec-cee | Contextual interfaces for explanation, attestation, and provenance | Normative |
| spec-se-appendix | Identifier rules, examples, and cross-spec patterns | Informative |
These repositories do not define meaning or behavior. They demonstrate that the specifications are internally consistent, coherent, and composable under formal reasoning.

These repositories define additional structural layers or boundaries that operate relative to the neutral substrate. They do not alter identity, structure, or recorded change.

Across all repositories:
- Identity precedes explanation.
- Structure and change are recorded without interpretation.
- Interpretation remains external, attributable, and contestable.
- Disagreement is representable and not forced to resolve.
- No domain semantics are embedded in the core.
The following are intentionally excluded from this organization:
- Domain vocabularies (except clearly labeled examples)
- Application schemas or data models
- Analytics, inference, or decision systems
- Governance or enforcement frameworks
- Visualization or tooling layers
Domain projects may claim conformance with these specifications, but are outside this core.
- To implement Structural Explainability, start with the specifications.
- To understand the justification, start with the papers.
- To verify coherence, consult the Lean formalizations.
Structural Explainability defines a neutral structural substrate that enables explainability by preserving identity, structure, and change while allowing disagreement to remain external, attributable, and unresolved.
At its core, Structural Explainability is concerned with identity. Stable identity is the precondition for explanation, provenance, and disagreement over time. Identity must persist independently of interpretation, authority, or consensus.
Structural Explainability defines the complete admissible space of representation. It simultaneously bounds what representation must not do and contains all representation that is permitted. Within this space, identity, structure, and change may be recorded, while interpretation, explanation, and judgment are constrained to remain external to the substrate.
- Accountable Entities define identity regimes that allow entities to persist across time and change.
- Evolution Protocol defines the evolution of structural relationships among those entities, recording change without embedding explanation.
Together, they form the structural substrate.
- Contextual Evidence & Explanations provide the structural interface by which external interpretation may be attached to, referenced from, and reasoned about, without entering or contaminating the substrate.
- Context tags, explanations, attestations, and provenance are not facts about the world; they are structured references to interpretive acts that occur outside the substrate.
Interpretation does not disappear. It is made explicit, attributable, and contestable.
Structural Explainability is not anti-interpretation; it is anti-implicit interpretation. Elements of interpretation may exist only in forms that do not alter identity, structure, or recorded change.
Structural Explainability is designed for plural systems: independent implementations that represent the same phenomena in different ways. Uniform naming, shared ontologies, or centralized authority are not required. Differences are addressed through explicit, accountable mappings rather than forced normalization or consensus.
Domains such as science, model development, and law do not alter the substrate. They specialize explanation by contributing controlled vocabularies for contextual scoping. These vocabularies are constrained by Structural Explainability and do not assert truth, causality, or normativity.
The result is a system that records reality without deciding its meaning, enables explanation without enforcing agreement, and supports long-term coordination across disagreement, institutional change, and time.
