UED Reconstruction Programme — Paper 9: ATT, Clocks, and Ordered Consequential Resolution

Paper 9 of the UED Reconstruction Programme reconstructs the timing regime by separating causal order, physical clock operation, propagation delay, Alignment Threshold Time (ATT), waiting time, relaxation, detector latency, synchronization, and observer registration. The time coordinate used in earlier papers is made explicitly operational: a physical clock consists of a persistent repetitive process, a discriminator, a counter, and a readout. Clock readings are therefore generated from counted physical cycles or transitions rather than assumed to measure an independently flowing temporal substance. For atomic clocks, transition frequency remains tied to persistent configuration-energy differences through the spectral architecture established in Paper 6. Environmental clock shifts are consequently treated first as measurable changes in physical process rates. Clock comparisons directly observe frequency ratios, and a universal multiplicative change common to all internal clocks cancels from those ratios. Alignment Threshold Time is given a strict operational definition as the first-passage duration from activation of a resolution process to the first crossing of a declared alignment threshold. ATT is explicitly distinguished from front delay, phase delay, group delay, coherence time, statistical waiting time, detector recovery, thermal relaxation, persistence time, amplification latency, and electronics latency. The paper also reconstructs two-way synchronization as a protocol-dependent inference, develops a complete source-to-record timestamp decomposition, and represents physical history through a partial order of resolved consequences. Metric clock time then provides a numerical coordinate on this ordered consequential history. Entropy production may define a statistical direction of macroscopic evolution in a declared regime, but it is not identified with time itself. Paper 9 establishes the timing discipline that later gravitational and redshift papers must preserve: gravity-dependent clock behavior must first be expressed through measurable changes in physical configuration and clock ratios before deeper temporal interpretations are introduced.
