C298 — The MT/LXX weave completes cross-bridge Flood coverage
24 September2026. The bridges16K/24K and reflected anchors Q6/Q1406 stay fixed.
The retained MT ON and LXX OFF fields together cover all six regular MT Flood boundaries. They give eight labeled comparisons representing six distinct coordinate comparisons. The SP OFF field adds none under these particular anchors and regular context.
| Regular boundary | BC base | Common gap | MT ON index | LXX OFF index |
|---|---|---|---|---|
| G3 start | 2460 | 5998 | 4 | — |
| G3 close | 2459 | 5999 | 5 | — |
| G2 start | 2458 | 6000 | 6 | 0 |
| G2 close | 2457 | 6001 | 7 | 1 |
| G1 start | 2456 | 6002 | — | 2 |
| G1 close | 2455 | 6003 | — | 3 |
The source equation remains C−B=2832. The MT ON field opens at5296 and LXX OFF at5290, so their annual selectors differ by six at shared coordinates. The two overlapping source coordinates5290 and5289 retain distinct cumulative profile labels. They do not count as four numerical dates.
The previously missing G1 requirements5288 and5287 are supplied by the existing LXX OFF field, at indices2 and3. This completes the regular Flood event coverage without creating an extra MT member or moving any source through an unauthorized Gear.
Both cumulative fields remain complete eight-boundary fields; the match uses selected members. Their regular counterparts are the independently defined three Flood years, each with a start and close. The one-year event width and the source annual-index spacing remain distinct mechanisms even where they align numerically.
The six-year weave therefore has an explicit operational consequence for the fixed cross-bridge comparison. It extends coverage from the higher regular Gears in MT to the lower Gears in LXX OFF, with the G2 pair shared. This is conditional on the given bridges and anchor choices, not independent evidence that they must be chosen.
The complete144-comparison ledger retains all three cumulative profiles and all failures. Six aggregate mathematical/domain checks and seven authentication checks pass, with identical replay. Author review only; no canonical or graph changes.
Best next bounded step — C299: lift the successful Flood-start comparisons by the existing600-year relations: regular Noah birth and cumulative Shem. Check the role change and determine which bindings survive without importing companions into MT. High is sufficient.
