# C326 — Completed four-endpoint fields: source review

**The complete regular configuration differs from File09's bilateral field.** Both contain two overlapping 500-year spans, and each contains three-point 460+40 or 40+460 patterns. Their ordered gaps, overlap widths, outer widths, event roles, and source/generated node classes are different.

The review adds only the already admitted MT counterpart D of each SP terminal C. Frozen C322 records supply every D and exact phase component. It verifies six annual fields and twelve exact component fields with 58 passing source/metric checks, recorded in `C326_Source_Results.json`. No endpoint was generated and no E operator was applied.

## Complete admitted endpoint table

A and C are SP OFF/T0/full430; B and D are MT restored-ON/T60/full430. All four endpoints retain the row's Gear and Noah-bound/Flood-bound biography. Positive BC labels decrease from left to right.

| Gear | Family | A: SP first role | B: MT first role | C: SP terminal role | D: MT terminal role |
|---|---|---:|---:|---:|---:|
| G1 | Noah birth → Shem birth | 3706 | 3246 | 3206 | 2746 |
| G2 | Noah birth → Shem birth | 3708 | 3248 | 3208 | 2748 |
| G3 | Noah birth → Shem birth | 3710 | 3250 | 3210 | 2750 |
| G1 | Flood start → Shem death | 3106 | 2646 | 2606 | 2146 |
| G2 | Flood start → Shem death | 3108 | 2648 | 2608 | 2148 |
| G3 | Flood start → Shem death | 3110 | 2650 | 2610 | 2150 |

The terminal counterparts are source records, not dates chosen to complete an analogy. A→B and C→D are the same-role context translations inherited from C322. A→C is the SP 500 relation; B→D is its existing MT counterpart. The first family preserves the Noah-to-Shem birth relation. The second preserves Flood-start-to-Shem-death and must retain that different event meaning.

## Whole-field comparison

File09 §3A.2.3, lines1045–1074, explicitly gives `14511 → 14471 → 14011 → 13971 BC` and classifies its 500 values as expanded intervals. It preserves Cainan's source lifespan as 460.

| Property | C326 regular fields | File09 declared cumulative field |
|---|---|---|
| Ordered adjacent gaps | 460 · 40 · 460 | 40 · 460 · 40 |
| Two overlapping spans | 500 and 500 | 500 and 500 |
| Overlap | 40 | 460 |
| Full outer width | 960 | 540 |
| Meaning of 460 | Same-role SP→MT context difference | Cumulative-Cainan interval |
| Meaning of 500 | Existing Noah-bound or Flood-bound biography span in each tradition/context | E-expanded interval in a declared cumulative completion |
| Four endpoint classes | Four admitted regular endpoints, retaining their context and event role | Source-controlled cumulative Creation members plus generated completion nodes |

The C325 A→B→C triple matches the ordered 460+40 portion of File09's field. Completing it with the existing D does not recover the entire File09 construction. Equality of the two 500 widths and the existence of matching three-point subpatterns do not equate the four-point configurations. In particular, File09's 540 outer field cannot be substituted for the regular field's 960, and its 460 central overlap cannot be substituted for the regular overlap of 40.

The mismatch does not reject either construction. It limits the claim to a partial arithmetic resemblance with different full configurations. Neither a whole-field metric identity under the stated endpoint order nor a common source-generation rule has been established.

## Source and phase restraints

File09's node-class register identifies 13971 as a generated younger male-forty close and 14511 as a generated older bilateral node (lines219–222). Its guard forbids promoting generated coordinates to independent File18 source rows or Primary anchors (lines486–490). The central 14471 and 14011 are source-controlled cumulative Creation-envelope members (lines914–919). C326's regular endpoints cannot inherit those cumulative node classes merely because some widths agree.

File09's cumulative/regular guard (lines279–283) requires a stated conversion and dependency before one state replaces another. File18 retains regular Cainan +130 versus cumulative +460 (lines1118–1157). C326's regular 460 is the already verified composition of local context differences, not a new use of Cainan's cumulative lifespan as a regular insertion.

For every exact field, D comes directly from C322's component at the same actual `−1/4` or `+1/4` phase as A, B, and C. This preserves all stated gaps. It introduces no new phase. C325's recorded cumulative ancestry remains attached to its corresponding paths: equal actual component offsets do not collapse opposite cumulative ancestry labels or identify different antecedents. The added MT Shem endpoint is admitted through the existing regular context correspondence; this review does not invent an additional cumulative derivation for it.

The MT textual/Arphaxad-bound 502 alternative remains distinct from the same-Gear Noah-bound 500. SP person-companion states are not imported into MT. Flood start remains an event boundary; no Flood companion or close is substituted. The repeated Gear and phase instances remain dependent realizations, not independent historical witnesses.

## Bounded consequence and next question

C326 closes the whole-field analogy test negatively while retaining C325's positive endpoint admissions. The source-prescribed E path remains unestablished. The sources license File09's local cumulative completion; this comparison does not transfer that license to the regular cross-context field.

**Suggested next bounded question, C327 unexecuted:** determine the independent constraints in the six regular four-endpoint fields after holding the two source contexts, role pairs, Gear and phase. Does completion by D supply an independent condition, or follow entirely from the held 460 context translation and 500 biography? Use only the frozen fields and symbolic dependency accounting, without fitting an anchor, adding a source endpoint, or applying E. No C327 calculation was performed here.
