C107 — The two junction paths give the same anchor correction on each branch

22 September 2026 · Step 5 of the authorized ten-step Mirror continuation (C103–C112).

N02 uses identical G1 Flood and Noah junctions, so both paths give 25. N04 compares its G2 records with the apparent row's G1 records; the two explicit regular differences are each 2, so both paths give 27. Equality of these two differences does not merge G1 and G2 events or move Creation.

The two regular comparisons and their reflected copies bring the extended graph to 104 nodes, 193 durations and 35 reflections. They add no numerical rank: the selected interval equations already entail them. Their explicit source labels show why the two residuals are equal. The remaining three free coordinates belong to relations outside these selected junctions and are not evidence of uncertainty in the supplied source dates.

This prepares a stronger structural test. If the carrier ratio is left unknown, do the two equal junction residuals require 25/23? That question concerns a parameterized family of diagrams, whereas the present graph rank holds all reported widths fixed.

Validation. 8 exact arithmetic/structural checks passed. The 16 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 §3 and Appendix A (paired Mirror); File_18 §§2.1.3, 3.1 and 6A (regular fields and cumulative source members); File_61 §11.2 (original backward Joseph +110); File_62 collateral-scope guards; C05 admitted apparent field; C43 frozen graph; C95 and C100–C102 named carrier rows; preceding current certificates. The forthcoming 529 × 4 × 2 cycle has not been explored. The declared phase model does not infer an unstated birthday or event month from an annual source row.

Best next bounded step — High sufficient. Leave the expansion ratio symbolic and eliminate the shared anchor difference between the two N02 junction equations.
