C231 — Three anchor choices agree only at the original attachment
23 September 2026 · Step 26 of 60, continuing C205.
Three choices must be stated separately: keep native Creation; keep the 868 gap to the moving cumulative boundary; or scale Creation with the whole configuration. They coincide at stage zero and separate immediately afterward.
| p | Stage | Fixed Creation | Origin holding gap 868 | Proportional origin |
|---|---|---|---|---|
| 3 | 1 | -4419 | -4879 | -110481/23 |
| 3 | 2 | -4419 | -5379 | -2762163/529 |
| 5 | 1 | -4417 | -4877 | -110435/23 |
| 5 | 2 | -4417 | -5377 | -2761105/529 |
C04 already established the resulting source exclusion. The center test now makes the incompatibility explicit. There is no additional anchor adjustment that simultaneously retains native Creation, the original 868 gap and proportional expansion of the whole interval at these stages.
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.
12 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/.
