# Prior 950/108/529 locator check

24 September 2026. Read-only prior-art lookup; no new calculation or numbered research. Paths are relative to `/workspace/scratch/2cd312e78692`.

**Result:** No explicit prior statement of `950+108=1058` or `598=490+108`, connecting Noah's 950 and the requested cross-context 490 to the C287 2K edge, was located in the bounded search. By contrast, the specific **SP Noah Gear g → restored MT Flood Gear g+1** relation and its `598+460=1058` decomposition are already explicitly reported in C10 and retained in C287. The 108 presentation must not be described as a newly discovered 2K endpoint relation.

## Positive prior art: exact adjacent-Gear endpoint identity

`active_c265/490d_C01_C265_Report_Locator_20260923.md`, line 16, selects C10 at:

`upload/490d_C01_C265_Complete_Window_Archive_20260923(1).zip!workspace/partition_3_7_5_5_20260921/490d_C10_3plus7_5plus5_and_the_Shared_1058_Interval_20260921.md`

- Lines 19–22 hold SP Noah at full430/Cainan OFF/Terah0 and the MT midpoint at full430/Cainan ON/Terah+60.
- Lines 70–92 derive and state the adjacent-Gear selector: primary SP Noah with next-Gear restored MT Flood start, or companion SP Noah with next-Gear restored MT Flood close. Four SP matches are admitted; the two LXX OFF aliases are primary/start cases. The close boundary is not an inherited SP person companion.
- Lines 94–101 explicitly give `1058=598+460` and `460=650−(130+60)`, distinguish the regular profile residual from cumulative Cainan's lifespan, and identify the rule with C08's next-Flood-Gear selection.
- Lines 161–166 give the primary examples `3706→2648` and `3708→2650`, retaining the stated profiles and Gear assignments.

`axis_ledger_work/C287/490d_C287_Four_Node_529_Normal_Form_20260924.md`, lines 7–16, names R as regular MT ON/Terah+60/full430 Flood and N as regular SP OFF/full430 Noah; `N−R=1058=2K`. Line 25 explicitly identifies MT G2 close/start against SP G1 companion/primary and MT G3 close/start against SP G2 companion/primary. Lines 27–29 retain matched component offsets and dependency limits.

`axis_ledger_work/C281/490d_C281_MT_Noah_Coverage_Boundary_20260924.md`, lines 7–20, separately retains restored MT births and the two adjacent-Gear 598 pairs, while excluding imagined MT companion births. This matters if a presentation proposes an intermediate same-role MT Noah endpoint: companion numerical positions do not automatically receive that source identity.

## What was not located

Targeted explicit-sum/subtraction searches found no requested 108 dissection. Selected C08/C10/C89/C90/C149 reports also produced no relevant 108/950 match. C08 lines 13 and 123 scope its 460+598 primarily to cumulative ON/OFF comparison; it must not replace C10's explicit alternate regular-frame binding. C90 lines 8 and 26–37 compares `460+598` with `506+552`; this is another already reported dissection of 1058, with its own interior roles, not the requested 950/108 dissection.

The local 108 hits concern unrelated objects: e.g. `axis_ledger_work/C276/490d_C276_598_Source_Relation_and_Translation_Increment_20260924.md`, line 225, has Jared/Exodus `2484=108×23`; `project_sources/40-File_18.Chronological_Data_Tables-20260919-141048-.md`, line 1057, has the Shelah comparison `6480=60×108`. Neither identifies the requested Noah/Flood residual.

## Bounds

Searched available C01–C265 locator titles and current report text, then only locator-selected archive reports C08, C10, C89, C90 and C149. Ran targeted `rg` searches in `axis_ledger_work`, `active_c265`, `supplement_intake_20260924` and `project_sources` for the named partitions, reversed sums/subtractions and 108 mentions, excluding replicated source/final-package trees and prior review notes in the narrow passes. Inspected C287/C281's relevant passages and C287's existing record labels. No archive-wide report reading, historical rerun, web search or new arithmetic test was performed. Absence is bounded to this lookup; no global novelty claim is established.
