Evidence Manifest — Structural Invariants of the Semantic Core

Associated Research Paper

Structural Invariants of the Semantic Core: A Cross-Implementation Study of Web-Based Semantic Reference Structures

Research area: Semantic Infrastructure

Evidence state: September 2026

Purpose

This evidence manifest identifies the Semantic Core implementation states preserved as the evidentiary basis for the cross-implementation study Structural Invariants of the Semantic Core.

The preserved resources correspond to the documented implementation states examined in the study and provide a stable historical basis for subsequent inspection, comparison, and challenge.

Evidence Boundary

The archived resources are preserved solely as historical research evidence. They do not constitute alternative, substitute, or canonical Semantic Core implementations.

Canonical authority remains with the original implementation URLs identified below.

The evidence package preserves the Semantic Core states examined in the study. Later Human Context Layer implementations, subsequent architectural developments, and other adjacent resources are not incorporated into the archived Semantic Core cases unless they formed part of the documented Core state under examination.

Subsequent changes to a live implementation do not alter the historical evidence state preserved by this package.

Primary Cases

The following five Semantic Core v3.0 implementations constitute the primary comparative set from which the candidate invariants were derived.

Cross-Category Control

The following implementation was examined after the candidate invariant set had been derived from the five primary cases. Its role in the study is therefore distinct from the primary comparative set.

Resource Classification

Audit Evidence Resources

The following resource classes preserve the implementation material directly relevant to the documented cross-implementation audit:

• root representation (index.html)
• about
• method
• sources
• changelog
• license
• legal
• privacy
• terms
• llms.txt

Associated Deployment Resources

The following resources are preserved as part of the documented deployment state but are not treated as independent evidence for the candidate invariants:

• robots.txt
• sitemap.xml

Integrity

The preserved evidence resources are identified through SHA-256 checksums. The checksums provide file-level integrity verification for the frozen evidence state.

Checksum data will be documented separately within this evidence package.

Interpretation

This manifest identifies the evidence examined in the associated research paper. It does not extend the findings of that paper, introduce additional Semantic Core properties, or establish claims beyond the evidentiary boundaries documented in the study.

The preserved material enables later readers to inspect the implementation states on which the analysis was based and to reproduce, challenge, or reinterpret the documented cross-implementation comparison.
