C239 — The fixed native 11-fold prefix inside all three 13-fold intervals
23 September 2026 · Step 34 of 60, continuing C205.
Keep the native Conquest reflection fixed inside each C01 chain. Its Creation prefix is always 5819=11×529. The remaining sourced tails to MT Flood, MT Noah and SP Noah are 1058, 1656 and 2306.
| p | Held Conquest reflection | Successive tails |
|---|---|---|
| 3 | 1400 | [1058, 1656, 2306] |
| 5 | 1402 | [1058, 1656, 2306] |
Only the first tail is 2×529. The later tails are obtained by moving the outer right endpoint while holding this internal source point fixed. This differs from expanding the 11-fold prefix along with the whole interval; that second operation begins in C241.
Evidence and scope
K=529 and r=25/23. BC base B means (B+1)t/Bn BC; reflected AD base A means AD At/(A+1)n. Their civil span is B+A in both seasonal components, with no year zero. Signed paired centers are −B and +A; the center model uses components ±1/4 and restores this separation after dilation. An interval center is geometry, not an event or a proposed universal Mirror axis.
Regular Gears are restricted to Noah/Shem/Flood. Creation and Conquest retain fixed source-field members; no fourth Gear is admitted. Generated coordinates, source-field membership and stored graph incidence are distinct. File_18/File_09 and the frozen C127 graph are unchanged. Earlier N01/N03 qualifications, the missing Shem join, closed primers and unestablished original Reports 11–25 remain unchanged. This packet selectively uses prior evidence; it does not rerun completed campaigns. Assertions and alternative placements are not independent historical witness counts.
