C206 — Two fixed Creation anchors and their interval centers
23 September 2026 · Step 1 of 60, continuing C205.
The two retained C01 chains each admit one affine map, Pₐ(t)=a+(25/23)(t−a), with their own fixed signed Creation center a. This makes the endpoint operation explicit; it does not combine the two Creation members into a new Gear.
| Creation origin | Reflected right centers | Interval centers |
|---|---|---|
| 4420t/4419n BC | 2458, 3056, 3706 | -1961/2, -1363/2, -713/2 |
| 4418t/4417n BC | 2460, 3058, 3708 | -1957/2, -1359/2, -709/2 |
Widths remain 13×(529,575,625). These centers describe the three complete intervals, not the named Noah-death point between successive right endpoints. C18 already explains the 868 source alignment using the Flood start/close distinction; its recovery is inherited provenance, not a new result of this batch.
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.
8 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/.
