# C74 — The 6325 image belongs to the backward cumulative Joseph portion

22 September 2026 · Step 2 of the authorized ten-step Mirror continuation (C73–C82).

**The intermediate image has a controlled cumulative source identity.** File_18 §6 and File_61 §11.2 derive Joseph's original backward portion by adding his 110-year lifespan to the Kohath boundary:

\[
1796+110=1906,\qquad1799.5+110=1909.5.
\]

File_18's Kohath envelope 1801–1794 translates by that same fixed 110 to a **derived Joseph-head envelope 1911–1904**. This is an inherited collateral field, not a newly printed raw patriarchal row.

| Branch | 6325 target | Underlying Kohath member | Moses-relative offset | Source status |
| --- | --- | --- | --- | --- |
| N02 | AD 1906t/1907n | 1796 | 0 | original backward Kohath-anchored cumulative Joseph portion; derived envelope member |
| N04 | AD 1908t/1909n | 1798 | 2 | original backward Kohath-anchored cumulative Joseph portion; derived envelope member |

N02's 1906 is the explicitly documented Moses/Nisan head. N04's 1908 is the +2 member obtained from Kohath 1798+110; both lie within the held envelopes. Their BC source pairs reflect to the displayed AD pairs, and the collateral 110 checks in both seasonal components.

The qualification matters. Joseph remains outside the direct Levi–Kohath trunk; 1796 is Kohath's Moses-line coordinate and 1906 is the derived Joseph head. The exact Aaron phase 1909.5 is retained separately. The ordinary member at 1908 is a cumulative envelope selection, not a regular Joseph Gear or an identification with the exact Aaron component.

Only the original backward portion is used. No H7/T14 clutch, localized −33, new biography, or expansion of the regular Gear scope is introduced. The 6325 middle stage can therefore be named precisely while retaining its derived status: **Creation to reflected original backward cumulative Joseph head**.

**Validation.** 9 exact arithmetic/structural checks passed. The 15 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 and exact phase); File_18 §§2.1.3, 2.4, 3.1 and 6/6A (regular fields and cumulative collateral source); File_61 §11 and File_62 collateral-scope guards (original Joseph portion only); frozen C15/C16/C22/C43/C65/C72 certificates and C01/C05/C09 reports (retained source, phase and family dependencies). The declared phase model does not infer an unstated birthday or event month from an annual source row.

**Best next bounded step — High sufficient.** Solve the exact source-field intersection for all three stages of this anchored 11-fold construction.
