This widens the endpoint domain after C284, without adding event types.\n\n**The same six2K/15K paths are the only all-K hits among36864 comparisons.** Every successful regular endpoint is MT, Cainan ON, Terah+60, full430. The other admitted Flood contexts add no all-K realization.\n\nThe canonical File_18 §3.1.4 table supplies the eighteen baseline Flood boundaries: three traditions, three Gears and start/close. MT/SP are native Cainan OFF here; LXX is native ON. For each, the eight already documented Cainan/Terah/sojourn contexts give144 qualified endpoint records. The calculation explicitly subtracts130 when deriving LXX OFF and subtracts215 for the alternate sojourn frame.\n\nThe source side retains256 independent cumulative pairs: two Cainan states for each of Shem and Flood, each with eight annual boundaries. Their product with144 targets is36864. Both leg widths must be integer multiples of529; a divisible total alone is insufficient.\n\n|Result|Count|\n|---|---:|\n|All-K paths|6|\n|Other comparisons|36858|\n|Successful regular context|MT ON, Terah+60, full430|\n|Successful widths|1058+7935=8993|\n\nThe successful sources remain native LXX ON Shem indices2–7 and LXX OFF Flood indices0–5, paired by i=j−2. The target Flood indices and Gear/start-close labels are unchanged from C282. Thus the earlier selection is not an artifact of testing only the two bilateral profiles.\n\nThe result is still domain-bounded. It covers only regular Flood endpoints and the specified cumulative fields. It does not establish global uniqueness, historical necessity, or independence of the six translated rows. The finite contexts are comparative source settings, not simultaneous historical events.\n\nThe evidence retains all256 source pairs, all144 qualified targets, failure counts and every hit. Replaying their full product reproduces the complete test; no failed endpoint is silently removed. Seven mathematical/domain checks and eight source-authentication checks pass. Author review only; standing files and graph unchanged.\n\n**Best next bounded step — C286:** admit the already scoped Noah/Shem birth/death endpoint records as well as Flood, preserving SP-only companions. Classify any additional all-K totals rather than assuming that every valid subdivision must total17K. High is sufficient.\n", "evidenceLinks": [{"id": "d-68301ab760bfbe2e", "title": "File 18"}]}
