C57 — The six-year Flood displacement is 460 minus 454

22 September 2026 · Step 5 of the authorized ten-step Mirror continuation (C53–C62).

The relevant six-year difference comes from comparing MT cumulative restored ON with LXX cumulative derived OFF. It is not a regular Gear displacement.

The differences total 454. The shared Abraham–Moses portion totals 1029, producing OFF sums 3425 for MT and 3879 for LXX. With the retained Conquest anchor 1406:

Accordingly the MT ON envelope 5296–5289 stands six years earlier than the LXX OFF envelope 5290–5283. Their coordinate overlap consists of 5290 and 5289. The opening O=5290 is the LXX OFF older boundary but, in the MT ON role, one year younger than its Moses-side 5291.

The source total 454 was already retained in the earlier source derivation. The advance here is its explicit use to explain the six-year displacement and the differing member roles in the current Mirror construction. The two coincident numerals do not merge the two profiles.

This also shows why the 5290 member must not automatically be called an opening in every cumulative profile. The next step follows the consequences for the matching 1058 prefixes on the two sides.

Validation. 8 exact arithmetic/structural checks passed. The 13 frozen dependencies passed hash verification; all three generated outputs replayed byte for byte in isolation, and the original dependencies remained unchanged. This step reads completed certificates and does not execute their campaigns.

Scope and provenance. Controlling File_18 and File_09 remain unchanged. Regular Gears apply only to Noah/Shem/Flood; SP person companions only to Noah/Shem. Creation and Conquest fields remain fixed. Native LXX ON, explicitly derived OFF, independent Flood start/close, and paired suffix inversion at January AD 1 remain in force. No civil year zero, upstream Gear transport, primers, Rounded campaign, or localized −33 is introduced. These are new continuation reports, not recovered historical Reports 11–25. Evidence is conditional on the supplied project model, not a proof of literary intention or independent historical dating.

Source locators. File_09 §0.4 rules 21–22 and the Creation Cell / Aaron Phase guard (week anatomy), §3 (paired Mirror); File_18 §§4.2 and 6A–6D (lifespans and cumulative fields); frozen C15/C16/C22 and C43/C46/C48/C50/C52 certificates (retained graph, unit, and domains).

Best next bounded step — High sufficient. Explain how the same 1058 gap uses a −2 offset on the LXX side and a +4 offset on the MT comparison side.
