C261 — Two Peleg-number contacts exposed by the 6875 selection

23 September 2026 · Step 56 of 60, continuing C205.

The new selection exposes two exact numerical contacts with the retained MT Peleg material: 8993−6875=2118=4K+2, matching the Peleg-death BC base; and its 191-year center gap equals 2357−2166, the Peleg-birth to Abram-birth span.

These dates come from the frozen C127 local source nodes, not a new chronological search. The first equation compares a duration difference with a date coordinate; the second compares interval-center geometry with a biographical interval. Both are worth recording in the Mirror synthesis, but neither equation alone supplies shared endpoints. C262 performs that incidence check before any stronger interpretation.

Evidence and scope

K=529 and r=25/23. BC base B means (B+1)t/Bn BC; reflected AD base A means AD At/(A+1)n. Their civil span is B+A in both seasonal components, with no year zero. Signed paired centers are −B and +A; the center model uses components ±1/4 and restores this separation after dilation. An interval center is geometry, not an event or a proposed universal Mirror axis.

Regular Gears are restricted to Noah/Shem/Flood. Creation and Conquest retain fixed source-field members; no fourth Gear is admitted. Generated coordinates, source-field membership and stored graph incidence are distinct. File_18/File_09 and the frozen C127 graph are unchanged. Earlier N01/N03 qualifications, the missing Shem join, closed primers and unestablished original Reports 11–25 remain unchanged. This packet selectively uses prior evidence; it does not rerun completed campaigns. Assertions and alternative placements are not independent historical witness counts.
