C214 — Two anchored maps related by a two-year translation

23 September 2026 · Step 9 of 60, continuing C205.

Every corresponding signed coordinate in N04 is N02+2. The correct relation is Pₐ₊₂∘T₂=T₂∘Pₐ. Applying the N02 map unchanged to the N04 Flood endpoint misses N04’s MT Noah target by 4/23.

Thus the two chains share an affine form and are related by translation. They do not share a single global fixed-anchor map. Choosing the other native Creation member is a source-field choice; the translation formula does not authorize Creation Gears. The fractional mismatch is retained exactly rather than rounded into an annual event.

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.

14 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/.
