# C311 — File_18 bounded source-rule review

Source reviewed: `project_sources/40-File_18.Chronological_Data_Tables-20260919-141048-.md` (2,671 lines). Review used whole-file targeted searches followed by relevant section context. No external sources or referenced dependency files were opened; no canonical source was edited.

## Finding

**No documented selector was found in this File_18 edition prescribing the exact transition from regular MT Noah birth→Flood start (Cainan OFF, Terah0, full430) at j0/2 to regular SP Shem birth→Shem death (Cainan OFF, Terah+60, minimum215) at j3…7 under C−B=2832.** The source supports the relevant endpoint/state ingredients and qualified comparisons. That support does not prescribe which tradition, biography, or variant context to select at each annual index.

This is a bounded absence finding about this source's searched rule, state, table, and comparison passages; it is not a claim that no such rule exists anywhere in the repository or could be separately authorized. The stipulated source field `C_LXXShem=5890−j`, `C_LXXFlood=5290−j` was held fixed. No new endpoints, anchors, Gear allowances, or phases were introduced.

## (a) Endpoint and state availability

| Source section and exact lines | Short evidence | What it establishes |
|---|---|---|
| §2.1.3 **MT Minimum-Regular table**, L1223–1238 | Noah `2843`; Flood `2243→2242` (L1237–1238). | The baseline Noah-birth→Flood-start 600 interval; the second Flood column is its closing boundary. |
| §2.2.1 **Noah and Shem ±2 anomaly**, L1254–1266 | Noah `2843–1893` / `2841–1891` (L1263); “Both are valid” (L1266). | Alternate regular Noah stations are admitted under the named local binding state. |
| §3.1.4 **Ordinary Flood Gears, fixed Arphaxad, and the SP midpoint**, L1540–1552 | Full430, Terah+60 OFF, MT/SP Cainan OFF (L1542); MT G3/G2/G1 starts `2460/2458/2456` (L1546). | The requested MT variant context and ordinary Flood Gear starts are source-supported. Flood closing boundaries remain separately typed. |
| §1.1 **The 60 + 155 + 60 pattern**, L538–548; §1.4 **Deriving any date**, L1096–1104 | “All three manuscript traditions share this fork structure” (L541); “Adam → Terah: add 60, 215, or 275 as needed” (L1101). | Terah-only and Sojourn-only are available regular variant contexts. Availability does not choose them by j. |
| §3 **SP Regular Baseline**, L1424–1436 | Native Sojourn `215`, Terah+60 OFF, Cainan OFF (L1427). | The source SP native baseline from which the requested Terah-only state is derived. |
| §3.2.1 **SP Noah/Shem field and named bindings**, L1571–1594 | G1/G2/G3 paired births/deaths (L1575–1579); “Matched birth/death endpoints preserve Noah 950 and Shem 600” (L1581). | SP Shem's source-supported 600-year biographies include primary and local lower-companion pairs under the declared Gears. L1573 expressly says these are **not six independently attested source states**. |
| §3.2.2 **Terah Dual-Lock: 145 versus 205**, L1628–1637 | “SP +60 Terah possibility remains state-valid where opened” (L1637). | SP Terah+60 is not prohibited by its textual 145-year Terah lifespan. The passage does not open it in response to the cumulative index. |

LXX source-field qualification: §6D **LXX Cumulative Chronology**, L2050–2066, explicitly includes Cainan (L2057), prints the native-ON Flood envelope `5750–5743` (L2063), and does not print a Shem row. §1.6.1–1.6.2, L1125–1147, distinguishes regular `130` from cumulative `460` and admits theoretical LXX removal, whose explicit example at L1147 is regular. §6D L2071–2072 additionally recognizes cumulative Adam heads with and without Cainan. These support a derived Cainan-OFF cumulative context, but the exact stipulated OFF Shem/Flood field is not itself a literal table row here. Do not describe it as an independently tabulated native LXX_OFF source row.

## (b) Generic comparison warrant, with limits

- §0 **File-function**, L81–95: File_18 is the “number source paired with the rule source” in the axiom/entity files (L81). Variants use documented mechanisms (L92). A shared number/span does not establish identity unless state, node class, tradition, and operator agree (L95).
- §0A.4 **Relationship to the multi-witness principle**, L526–528: traditions are expected to harmonize horizontally and vertically; this is structural inference / providential language, not proof of direct scribal intent.
- §0A.5 **Predictive power**, L530–532: candidate values become useful only after table/state/operator/dependency checks support them.
- §3.2.1, L1585–1594: Noah/Shem have qualified cross-Gear endpoint-comparison permission; qualified Noah↔Flood comparisons are allowed. This permits appropriately labelled comparisons; it does not command the MT→SP switch or equate the two biography types.
- §0.1d **Modal-state processing rules**, L315–328: read each value under its local state; regular and cumulative methods differ; SP −1 stays local to Noah/Shem (L324); cumulative seven-year spans retain individual member labels (L328).

## (c) Selector and conflict assessment

No passage located specifies C−B=2832, annual-index j0/2 versus j3…7 selection, or an instruction to replace MT Noah→Flood with SP Shem birth→death when moving through that cumulative envelope. Whole-file literal searches returned no `2832`, `5890`, `LXX_OFF`, `j0` through `j7`, or `selector`. The `5290` occurrence at §6B L1997 belongs to an MT restored-Cainan Flood / Christ-Key note, not this requested selector.

The substantive risk is an **evidential overclaim**, not a demonstrated contradiction in the available 600-year pairs: endpoint availability plus harmonic comparison permission cannot be reported as a documented deterministic context-selection rule. The source also explicitly bars transferring SP's −1 companion to MT/LXX (§2.2.1 L1282; §0.1d L324), and it keeps regular binding behavior distinct from cumulative propagation (§1.5 L1106–1114). This review does not broaden the current regular Noah/Shem/Flood Gear scope.
