This chapter defines the evidentiary framework used across all Parts of this document. Because the ecological collapse and restoration architecture involve multiple biological domains—microbial ecology, immunology, epithelial biology, metabolism, motility, and neuroimmune signaling—clarity about evidence type, weight, and inference boundaries is essential.

1. Overview
Interpretations in this document draw from three categories of evidence:
The goal is transparency: distinguishing what is directly measured, what is derived from established biology, and what represents a necessary inference to integrate ecological behavior into a coherent system model.
—
2. Human Clinical Evidence
Human clinical evidence forms the top tier of interpretation and is relied upon whenever available.
2.1 Metagenomic sequencing
Direct shotgun metagenomic results anchor ecological interpretation.
Your datasets (2022 → 2024 → 2025) provide:
These findings dictate the core interpretation of ecological collapse.
2.2 Clinical events mapped to ecological data
Human-level events—iron infusions, RA flares, hives, motility sensations, systemic symptoms—add temporal resolution to mechanistic interpretation.
These events are used strictly as timeline markers, not as subjective diagnostic drivers.
2.3 Laboratory trends
Inflammation scores, permeability scores, autoimmune markers, and nutrient trends are used as supportive evidence.
2.4 Structural role
Human evidence sets boundaries on interpretation and constrains speculative pathways.

3. Animal Model Evidence
Animal models (primarily murine, occasionally porcine) fill gaps where direct human evidence is sparse but mechanisms are conserved.
3.1 Use cases
Animal data are used when interpreting:
These mechanisms are highly conserved across species and are applicable to human interpretation.
3.2 Boundaries
Animal evidence is never used to infer symptom patterns or subjective experiences.
It is restricted to mechanistic insight.
3.3 Examples
These mechanisms underpin several structural arguments made in previous chapters.

4. In Vitro and Mechanistic Evidence
In vitro studies clarify biochemical and cellular dynamics that are conserved regardless of species.
4.1 Use cases
These studies inform:
4.2 Examples relevant to this case
4.3 Limitations
In vitro systems lack the complexity of host–microbe–immune interactions.
Their use is limited to elucidating narrow mechanistic pathways.
—
5. Inference Boundaries
Some interpretations require inference, especially where human testing cannot directly measure certain processes (e.g., redox gradients, mucin dynamics, biofilm architecture).
Inferences are made only when:
5.1 Explicit inferences in this document
Examples of necessary inferences:
5.2 Non-inference domains
No inference is used where direct sequencing, scores, or clinical events suffice.

6. Documentation Standards
6.1 Transparency
Every major mechanistic claim is tied to:
6.2 Distinguishing evidence from interpretation
Each chapter separates:
6.3 Avoidance of unwarranted generalization
Interpretations apply only to the system described here.
No extrapolation to unrelated physiological states is made.

7. Evaluated and Excluded Mechanistic Drivers
Part of evidence stratification involves ruling out plausible alternative drivers.
Excluded mechanisms are documented in
Appendix D — Excluded Mechanisms.
Current evidence does not support:
Their exclusion forms part of the structural confidence in the core interpretation.
