The UR-Axiom of Tensor Field Dynamics Logical Unfolding of a Single-Axiom Theory

This work states the core claim of Tensor Field Dynamics in its sharpest form: field tension or space tension is the one ultimate, non-derivable foundational reality of the universe. From this UR-Axiom, no multi-axiom basis, no second substance, and no external carrier are admitted. Instead, the document develops a logically closed field description in which the ground state, minimal oscillation, amplitude and phase structure, interference, resonance, local field objects, matter, dynamics, light, cosmic structure, and the fundamental ordering quantities of the field appear as internal organisational forms of the same field reality. The methodological core is as important as the ontological claim: the document strictly separates the pure UR-Axiom, its first unfolding, the mathematical basic description, and later canonical or test-related specifications. Its claim is therefore not to present yet another model component, but to lay out an audit-proof foundation for a single-axiom theory that develops its entire physics from one single supporting principle.
