Closed Coupling Structure of Tensor Field Dynamics Complete Solution of Task 1 within the Phoenix Axiom

This work provides the complete model-internal solution of the closed coupling structure of Tensor Field Dynamics within the current Phoenix Axiom. Its objective is to show that orbital dynamics, rotational dynamics, light deflection, Shapiro delay, and gravitational redshift do not arise from separate recipe blocks, but follow from the same canonical source structure. The document demonstrates that the static exterior solution is determined by exactly one effective exterior source strength and that field-optical effects do not introduce a second independent source, but appear as the canonical projection of the same TFD source. The coupling structure of the theory in the static exterior region is therefore mathematically closed, formulated as TFD-internal and audit-proof, and explicitly separated from later external comparison tasks with measurement data.
