# C329 — Two named Noah/Shem bindings: source review

**Noah's 950 partition retains residual 490, and Shem's 600 lifespan retains residual 140, under both named bindings.** The two former 500 paths instead become 502, changing their residual 40 to42. The Noah-to-Shem-death span changes from 1100 to1102, with residual 640→642.

The review checks 50 annual comparisons and 100 coherent same-phase realizations from frozen C322: 233 checks pass. Both modes have six positive role patterns. The separate main audit owns the complete mixed-phase enumeration.

| SP interval partitioned at its MT first-role counterpart | Noah-bound d/r | Arphaxad-bound d/r |
|---|---|---|
| Noah birth → Shem birth | 500 /40 | 502 /42 |
| Noah birth → Flood start | 600 /140 | 600 /140 |
| Noah birth → Noah death | 950 /490 | 950 /490 |
| Noah birth → Shem death | 1100 /640 | 1102 /642 |
| Shem birth → Shem death | 600 /140 | 600 /140 |
| Flood start → Shem death | 500 /40 | 502 /42 |

In every row, d=460+r. SP remains primary OFF/Terah0/full430; MT remains restored-ON/Terah60/full430. Noah birth/death and Flood start remain G2 in both traditions. Only Shem's matched birth/death pair changes from G2 to G1. All endpoints are existing records, and each same-role SP→MT correspondence still differs by 460.

The source permits these **specific modal comparisons**. File18 §1.3.5, lines755–771, retains Noah-bound/Flood-bound and Arphaxad-bound/textual states without treating either as a correction. MT lines1237–1266 provide the literal Noah/Flood and Shem rows and the valid alternative Shem biography. SP lines1275–1282 and 1587–1594 explicitly retain G2 primary Shem and G1 Arphaxad-bound Shem. This is not permission for an unrestricted cross-Gear generator or a claim that the alternative is one coherent-Gear biography.

Keeping both Shem endpoints together preserves Shem 600. Keeping Noah's endpoints fixed preserves Noah 950 and its 490 residual. The Noah-to-Flood 600/140 row is also invariant. In contrast, the 40 residual depends on the Noah-bound 500 choice; its survival must not be claimed across both source modes.

SP primary Noah death retains its inclusive/harmonic qualification (File18 line1581). The SP companion is excluded, MT receives no companion, and Flood start remains an event boundary. The exact comparisons use existing equal actual-phase components; they do not assign textual birthdays or merge inherited cumulative ancestry labels.

The invariant residues are robustness results within these two declared modes, not new witnesses or a source-prescribed E path. The changed residues do not invalidate either source binding. **No C330 calculation was performed.**
