The Realization Arrow of Time

The Realization Arrow of Time presents an operational framework for investigating the transition from physically admissible possibility to realized causal history. The work distinguishes between physical possibility, occurrence, consequence formation, present-state reconstruction, and realized history, while explicitly avoiding the introduction of an independent temporal force or an unsupported history variable. The accompanying validation programme examines event–consequence ordering, state reversibility versus historical non-contraction, operational accessibility, present-state sufficiency, apparent history dependence, latent-state reconstruction, process memory, and cross-domain physical consistency. The current results support a constrained interpretation: realized history is causally relevant because it produces the present physical state, but within the tested systems and state representations no independent predictive contribution of realized history beyond sufficiently represented physical state and process information was established. This Zenodo research object includes the full report, a reviewer navigation and reproducibility supplement, three reproducibility archives containing data, code, frozen protocols and formal result records, a v21–v24 history-dependence Master Record, and a SHA-256 integrity record. The publication explicitly separates current validation evidence from future experimental discrimination. Appendix G defines the next-stage matched-state / different-history experiments required to test whether any irreducible residual history contribution exists after increasingly complete physical-state reconstruction.
