Step 3 of 10 in the C344–C353 authorization.\n\n**The primary598 interval has a complete650 image under the existing Noah-held E comparison.** Both endpoints match actual Shem records:\n\n| SP Noah held | Input restored-MT Noah→next Flood | E image: SP Shem→base-MT Shem |\n|---:|---|---|\n| 3706 | 3246→2648 =598 | **3206→2556 =650** |\n| 3708 | 3248→2650 =598 | **3208→2558 =650** |\n\nThe first endpoint match is the460→500 relation already checked in C325; the second is the1058→1150 relation in C338. Their joint interval image is therefore a connected reading of existing results. C01 already recorded598/650 scalar and source gains in another placement.\n\nThe two ratios give different, source-realized outputs:598×300/299=600 and598×25/23=650. Their quotient is12/13, hence600:650=12:13. This does not license a new12/13 source operator or identify the endpoint pairs.\n\nCompanion images do not match their actual Shem records. In the named502/98 control, the actual primary Shem pair remains650 apart, but both selected Shem endpoints lie two years below the E images. Equal interval length alone does not supply the same endpoint map.\n\nThe next question is whether File_02’s gap conversion can also represent the coherent change of Noah’s complete biography. That distinction matters before treating its successful birth-endpoint match as a full affine action.\n\n## Verification and limits\n\n18 main checks and 17 frozen-input/predecessor authentication checks passed. A second main replay produced byte-identical DATA/RESULTS. These checks and the source interpretation were performed by the root agent; no new independent-agent review is claimed. All frozen originals and standing controls remain unchanged. Verification counts are not independent-witness counts.\n\nCombines previously verified endpoint matches; no new scalar discovery, source-prescribed global action or12/13 operator is claimed.\n\nMirror/529 focus: K=529, E=25/23, P=70/69. Global paired Mirror January AD1; local junction January AD2; no civil year zero. Regular Gears are Noah/Shem/Flood only. SP minus-one person companions remain local to SP Noah/Shem; Flood close is a separate boundary. No upstream/cumulative Gear, new endpoint or phase, fitted anchor, global axis, primer reopening, canonical or graph edit. Capture now; canonize later. Source identity, context, modal binding, generated coordinates and phase ancestry stay distinct.\n\n## Decision after this result\n\n**C347, proposed and unexecuted:** Compare the300/299 birth-endpoint realization with the complete admitted MT Noah birth/death pairs. Test whether it is a950-preserving Gear translation or a whole-biography affine scaling, and retain their distinct source permissions.\n\nBoth ratios now have explicit endpoint interpretations. The strongest remaining ambiguity is whether a successful gap conversion also transports a biography.\n", "evidenceLinks": [{"id": "d-24203a4c3b282f9b", "title": "File 02"}]}
