Evidence & Canonical Reference Layer

The Evidence Layer and Canonical Reference Layer function as a unified structural pair within the ARAYUN_173 architecture. Together they define the empirical foundation and formal reference framework against which system-law claims are evaluated.

Architectural Pairing

The Evidence Layer provides empirical validation: audit-grade artifacts, verification contexts, and empirical proof paths derived from the four-paper research architecture. It establishes that system-law claims are falsifiable — they can be tested, reproduced, and confirmed against observable structural conditions.

The Canonical Reference Layer provides formal resolution: it defines the authoritative terminology, symbolic conventions, and non-negotiable reference points that govern interpretation across all system layers. It ensures that terms carry deterministic meaning — no semantic drift, no domain-specific reinterpretation.

Why They Are One

Evidence without canonical reference is uninterpretable. Canonical reference without evidence is unverifiable. The two layers are structurally interdependent:

• Canonical terms define what is being measured — Evidence provides the measurement
• Canonical structure defines how claims are evaluated — Evidence provides the evaluation artifacts
• Canonical resolution prevents semantic disputes — Evidence prevents verification disputes

Regulatory and Audit Function

For regulators, auditors, and integrating entities, the Evidence & Canonical Reference Layer together form the structural basis for evaluating ARAYUN_173 claims:

• Article 15 (Accuracy & Robustness): Evidence of coherence stability under perturbation — measured against canonical definitions, not output similarity
• EU AI Act Mapping: Canonical resolution of regulatory terms to structural conditions — preventing documentary reinterpretation
• Audit Protocol: Verification anchored in canonical reference points — audit artifacts traceable to formal definitions
