ADDENDUM - The Sexagesimal Reduction Model: Synthesizing the Sumerian King List, Genesis Genealogies, and the Anthropological Record

This Technical Addendum deploys the Stratigraphic Overlay Model (SOM) against the initial Sexagesimal Reduction Model (SRM) output, isolating and resolving a 500-year tabular fracture caused by the vertical stacking of concurrent post-3404 BCE dynasties across Larak, Sippar, and Šuruppak (WB 444, WB 62, and Genesis 5). By deconstructing this multi-city concurrency and tri-generational co-regency, the model demonstrates that both traditions independently preserve an identical 600-year terminal span for the final antediluvian patriarch, recalibrating the unadjusted 2348 BCE linear sum by 500 solar years to correctly anchor the historical flood terminus at 2848 BCE (c. 2850 BCE). This resolves the new found SOM fracture by aligning the terminus date to the terminal Jemdet Nasr / Early Dynastic I inundation stratum excavated at Tell Fara (ancient Šuruppak) and Kish. This synchronized timeline serves as the foundation for the ensuing multi-part series.
