This document presents the author’s preprint version of Total State–Space Coexistence Theory, a structural framework addressing time, probability, multiplicity, and experience. The work treats time as an ordering relation rather than a flowing entity, probability as a structural measure over coexisting outcomes, and experience as index-local access within a complete state-space. Classical paradoxes related to time, measurement, and single-history assumptions are handled through structural separation rather than elimination. This preprint is intended for academic reference and archival purposes.The formally published edition of this work is available via Amazon KDP in paperback and Kindle formats.
