This concluding paper synthesises the NPF/CNI series, articulating a covenant for epistemic resilience. It revisits neurodiversity as collective strength, positions synthetic intelligence as part of the epistemic immune system with FEN metrics (proto‑awareness, auto‑reject), elaborates falsification conditions, and issues an open invitation to adversarial collaboration. The covenantal statement commits to honesty, corrigibility, inclusion, open science, and flourishing.

Methodological naturalism is the most justified inquiry principle available—but it is a principle, not a presupposition, and not a metaphysical claim. This chapter explains exactly what it says, what it doesn't say, why it works, and where it reaches its limits. The single most important distinction: methodological vs. metaphysical naturalism.
