Fixed bridges and reflected anchors from the axis report.\n\n**The highlighted6000 equality extends to four source-qualified MT comparisons, with gaps5998–6001.** It follows one fixed affine source relation, not four independently fitted endpoints.\n\nFor regular MT Flood base B, use the16K landing relative to reflected Christ Q6: g_R=8464−B−6. For cumulative MT ON Flood base C, use the24K landing relative to reflected Conquest Q1406: g_C=12696−C−1406. Equality is exactly\n\nC−B=12696−8464−(1406−6)=2832=8K−1400.\n\nAll six regular Flood start/close records are compared with all eight cumulative MT ON annual boundaries.\n\n|Cumulative index|Cumulative BC base|Regular MT Flood|Common gap|\n|---:|---:|---|---:|\n|4|5292|G3 start2460|5998|\n|5|5291|G3 close2459|5999|\n|6|5290|G2 start2458|6000|\n|7|5289|G2 close2457|6001|\n\nThe6000 row is the normal G2 Flood start paired with cumulative index6. Both seasonal components give the same gap when compared with the corresponding component of their own reflected anchor. Q6 and Q1406 are on the AD side; literal BC terminals would be different comparisons.\n\nThe G1 start and close would require cumulative5288 and5287. Those are outside this MT ON field, so the present four-row extension stops at its closing boundary. They are requirements, not newly added MT cumulative members.\n\nThe bridge difference8K and anchor difference1400 account for the source offset2832. Thus the equality compares two generated landing-to-anchor spans while preserving their different source roles and modes. It is not an identity of the regular Flood with the cumulative annual source, or a new historical path between them.\n\nThirteen mathematical/domain checks and eight authentication checks pass. All48 comparisons, including failures, replay identically. Author review only. No primer, scale, axis or event search has been opened.\n\n**Best next bounded step — C298:** test the same six regular endpoints and fixed anchors against the already retained LXX OFF and SP OFF cumulative Flood fields. This asks whether the known MT/LXX six-year weave fills the two missing G1 requirements. High is sufficient.\n"}
