# Prior 460-residual locator check

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

**Finding:** The bounded lookup did not locate a prior explicit report of the requested regular cross-context residual identities: MT restored ON/Terah60 Noah birth → SP OFF Noah death = 490, the corresponding SP Noah 950 = 460 + 490 partition, Shem 600 = 460 + 140, or Noah birth → Shem death 1100 = 460 + 640. This is a bounded search absence, not an archive-wide novelty claim. The source-qualified endpoint chains and the common 460 translation are already established; consequently an explicit residual census would refine the presentation of inherited endpoints and relations, not supply independent numerical witnesses.

## Closest same-context prior result

- `axis_ledger_work/C322/490d_C322_Whole_Biography_460_and_Joint_Support_20260924.md`, lines 5–15: all three primary same-Gear biographies transfer uniformly by 460 from SP OFF/Terah0/full430 to MT CainanON/Terah60/full430. Lines 7–11 list all five endpoint roles in both chains; line 13 retains `500+100+350+150`, Noah 950 and Shem 600. The qualification is Noah-bound/Flood-bound 500/100; the separately selected textual 502 state remains distinct. The residuals requested in this locator task are not explicitly named there.
- `axis_ledger_work/C325/490d_C325_Existing_460_40_500_Endpoint_Chains_20260924.md`, lines 5–21: six existing 460+40=500 triples, Noah birth → Shem birth and Flood start → Shem death, with the same source contexts and physical-phase controls. This reports the 40 residual, not the requested 490/140/640 residuals. Lines 19 and 27 already warn that the extra subtraction is dependent on the held relations.

## Older motif or different endpoint relation

- `active_c265/490d_C01_C265_Report_Locator_20260923.md`, line 168, locates C162. Selected archive member `upload/490d_C01_C265_Complete_Window_Archive_20260923(1).zip!workspace/mirror_C156_C205_529_Source_Grammar_20260923/C162/490d_C162_529_Mirror_Bounded_Step_20260923.md`, lines 5–11: regular `650−190=460` comes from SP–MT Noah coordinates and MT Cainan/Terah switches; cumulative Cainan 460 is a different operator. It also records `598+460=1058=2K`. This is genuine prior art for the regular context difference, but does not report the requested cross-role death residuals.
- `project_sources/32-File_09.Cumulative_Architecture-9-.md`, lines 949–961: `460+30=490` is a cumulative Creation/Apparent-Adam cell translation. It uses different endpoints and operators; scalar 490 is not the requested regular Noah death identity.
- `project_sources/12-File_69.Enoch_Centered_Genealogical_Accordion-20260823-145801-.md`, lines 4262–4291: the Noah-to-Flood 600 is partitioned as `110+490` within the Lukan-head comparison. It does not partition SP Noah 950 or Shem 600 at an MT restored endpoint.
- `active_c265/active/milestones/mirror_C156_C205_529_Source_Grammar_20260923/C191/490d_C191_529_Mirror_Bounded_Step_20260923.md`, lines 5–11: Isaac-death/generated-complement 460 expands to 500 about 4K. Different people, generated endpoints and operator.
- Selected archive member `upload/490d_Complete_Study_Handoff_20260917(3).zip!490d_Fresh_Start_20260917/current_reports/490d_SP_LXX_Shared_1100_Articulation_Audit_20260917.md`, lines 10–17 and 33–42, 53–80: the older shared 1100 is regular Shelah birth → Famine close, with SP/LXX cumulative comparison roles; not Noah birth → Shem death. The Cainan–Noah two-Keys report selected from that same index concerns cumulative Noah/Famine expansions, not these regular residual partitions.

## Search bounds

Consulted C01–C265 report locator titles, the September-17 completed-work index and available later report titles. Ran targeted `rg` searches over Markdown in `axis_ledger_work`, `active_c265`, `supplement_intake_20260924` and `project_sources` for the three explicit partitions, reversed sums/subtractions, named Noah/Shem residual phrases, and the relevant G1/G2/G3 endpoint pairs. Excluded replicated frozen-source/final-package trees from the narrower passes after their duplicates appeared. Inspected only relevant source passages and locator-selected historical reports (C162, C57, C191, Cainan–Noah two Keys, SP/LXX shared 1100); did not read all historical reports, rerun campaigns or use web search. No future research result was calculated.
