The Civilizational Threshold - The TUDOK Operator as a Universal Pre-Ethical Minimum Condition

One-minute summary:This preprint introduces the TUDOK Operator as a universal pre-ethical entry minimum: a runnable truth-primacy discipline at the moment of decision and communication. The work is not an empirical impact evaluation, but a structural (architectural) proof showing that, in threshold situations, a worldview-neutral runnable minimum can be logically necessary and culturally acceptable—allowing co-running across divergent systems. Scope and limitations- Scope: runtime minimum for decision/communication, reality-fidelity and auditability of the decision chain, civilizational threshold logic.- Out of scope: technical implementation and empirical validation (see companion preprints). How to readComplexity increases by design. Recommended pass: (1) definition → (2) minimum condition → (3) consequence → (4) runtime consequence.
