A Locally Latched Speed-Swapped Clock-Transport Test of Directional Clock Response

This project presents an idealised thought experiment examining directional clock transport without requiring synchronised clocks at spatially separated endpoints. Two fixed markers define a straight measurement path. A moving clock locally records its own reading as it crosses each marker, so that the measured quantity is an elapsed clock interval recorded on a single clock. Measurements are performed in opposite directions at two different speed magnitudes, with the high and low speeds deliberately interchanged between directions. Two complementary observables are defined. A(v) tests for a directional difference in accumulated clock reading at fixed speed. D = A(v_H) - A(v_L) tests whether that directional difference changes with speed. Special relativity predicts both directional observables to vanish in the idealised inertial configuration. An illustrative longitudinal photon-clock model is used to examine how a hypothetical physical propagation anisotropy could enter a transported clock. The analysis also distinguishes physical directional clock behaviour from apparent one-way anisotropy produced solely by a synchronisation convention. The proposal does not directly determine the conventional one-way speed of light. Its purpose is to examine directional clock-transport behaviour itself and its possible relevance to the wider one-way propagation problem.
