# C325 — Source identity, phase, and interpretation review

**Six annual triples, in two role patterns across three Gears, use existing admitted endpoints. Twelve exact component triples survive with all three actual phases equal.** They supply concrete cross-context 40-year legs. They do not establish an anchored `25/23` prescription.

The independent review used frozen C322 biography records and C314 primary records. The companion results record 93 source-identity, context, rail, modal-binding, phase, and finite-domain checks; all pass. The tested menu is 75 annual triples and 600 exact phase triples. No C326 calculation was performed.

## Admitted paths

All labels below are positive BC labels in chronological order, from older A to younger C. A and C are SP OFF/T0/full430 primary biography endpoints; B is the same-Gear MT restored-ON/T60/full430 counterpart of A, with the same event role.

| Gear | A: SP Noah birth | B: MT Noah birth | C: SP Shem birth | Path |
|---|---:|---:|---:|---|
| G1 | 3706 | 3246 | 3206 | 460 + 40 = 500 |
| G2 | 3708 | 3248 | 3208 | 460 + 40 = 500 |
| G3 | 3710 | 3250 | 3210 | 460 + 40 = 500 |

| Gear | A: SP Flood start | B: MT Flood start | C: SP Shem death | Path |
|---|---:|---:|---:|---|
| G1 | 3106 | 2646 | 2606 | 460 + 40 = 500 |
| G2 | 3108 | 2648 | 2608 | 460 + 40 = 500 |
| G3 | 3110 | 2650 | 2610 | 460 + 40 = 500 |

The first 500 is the Noah-to-Shem birth relation. The second is Flood-start-to-Shem-death, derived within the held Noah-bound biography from Shem's 100 years before the Flood and 600-year life. It is not a second Noah begetting event. The five-role menu contains no further successful role pattern. Three Gear instances and their two components do not constitute independent historical witnesses.

## Admission and counting controls

Each selected A/B pair already occurs in C322's fifteen primary same-role correspondences. Each selected C is an existing endpoint in the same SP biography. Nothing was generated by an expansion. SP person records keep `rail=primary`; MT records have no SP person rail. Flood start is an event boundary, with no person-companion status. Flood close was not added to the five-role menu.

File18 §1.3.5, lines755–771, explicitly preserves the Noah-bound/Flood-bound state beside the Arphaxad-bound/textual state. C322's held MT same-Gear Noah/Shem pair is 500. Its Noah G2/Shem G1 alternative remains 502 and must not replace the same-Gear binding. File18 §3.2.1, lines1571–1594, controls the matched SP primary biographies and their distinct mixed/cross-Gear alternatives. The census therefore does not resolve 502 into 500 or reject the textual state.

SP primary Noah death retains its inherited inclusive/harmonic qualification even though it supplies no successful A role here. Coordinate comparison does not erase source counting qualifications. File18 §3.1.4, lines1540–1552, separately controls ordinary Flood Gears and event start/close. Current scope remains regular Noah/Shem/Flood only; source passages with wider scope do not authorize additional operations in this step.

## Exact phases and ancestry

C322 records each endpoint as its annual center plus the existing `−1/4` or `+1/4` component. The exact triples use only those frozen components. In all twelve successes, A, B, and C have the same actual component phase. Mixed actual phases fail the exact 460/40/500 requirements; an annual-center match alone is insufficient.

C314's three primary source biographies agree with the relevant C322 Noah/Shem source records and exact component values. C314 separately records opposite cumulative ancestry phases for its Noah and Shem construction. That ancestry reversal is not an instruction to reverse an actual endpoint's phase when forming C325. Actual component values and ancestry labels must remain separate fields. The review checks their agreement without merging the paths or rerunning C314 research.

## Interpretation and next bounded question

The result is stronger than a bare scalar coincidence: there are concrete source-admitted B→C 40-year legs. But `A−B=460`, `B−C=40`, and `A−C=500` are an additive endpoint path. No E transformation was executed; no source passage was found in C324 that prescribes holding A and expanding its A→B duration to C. The surviving role patterns remain an analytical selection from a declared finite menu. C324's bounded source conclusion is unchanged.

**Possible C326, unexecuted:** compare these typed regular endpoint patterns with File09's explicitly declared bilateral `40+460+40` completion field. Ask which event/context correspondences are already controlled and which require an additional endpoint or selection premise. Preserve File09's cumulative scope, source versus generated node distinction, and the difference between an additive path and a prescribed E execution. No bilateral field construction, anchor choice, or subsequent calculation is performed here.
