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.
