C252 — The source Conquest-to-Flood tail is 1056, not 1058
23 September 2026 · Step 47 of 60, continuing C205.
Each admitted row has a source-qualified outer tail from reflected Conquest to its final reflected Flood boundary of 1056=2K−2. Its expansion-stage subdivision is 506+550.
| Conquest center | Generated middle center | Sourced Flood center | Outer tail |
|---|---|---|---|
| 1399 | 1905 | 2455 | 1056 |
| 1400 | 1906 | 2456 | 1056 |
| 1401 | 1907 | 2457 | 1056 |
| 1402 | 1908 | 2458 | 1056 |
| 1403 | 1909 | 2459 | 1056 |
| 1404 | 1910 | 2460 | 1056 |
The outer endpoints are sourced; the internal expansion point is generated. This tail differs by two years from C09’s original 1058 Conquest-to-next-Gear-Flood tail. Keeping that residual is essential: erasing it would collapse two different endpoint selections and conceal the connection between 11×625 and 13×529.
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.
18 step-specific checks and 19 frozen-input checks passed. Exact inputs, results and predecessor hashes are in the accompanying JSON records; calculation code is in the evidence archive. Source dependencies are identified in the body and frozen in sources/.
