Step 1 of 10 in the C354–C363 authorization.\n\n**The Shem comparison succeeds on both matched SP rails as well as MT and LXX.** In the frozen C286 register,32 tradition/rail/context families contain96 matched600-year biographies and64 adjacent-Gear598-year comparisons. Every598 input has two existing600 repairs: hold death and select birth+2, or hold birth and select death−2. The128 repaired instances repeat one local rule; they are not128 independent witnesses.\n\nFile_18 §§2.2.1 and3.2.1 separately supply the600 lifespan and the paired birth/death states. File_02 §6.3 supplies the598×300/299=600 gap conversion. A598 comparison crosses biography states; it is not a new598-year lifespan. Named Cainan, Terah, sojourn and SP rail settings remain fixed within each comparison.\n\n| Primary full-430 pair | Adjacent comparison | Hold death | Hold birth |\n|---|---|---|---|\n| MT G1/G2 |2556→1958 =598 |2558→1958 =600 |2556→1956 =600 |\n| SP G1/G2 |3206→2608 =598 |3208→2608 =600 |3206→2606 =600 |\n\nG2/G3 repeats the same rule two years earlier. SP companions retain the same598 because both selected person endpoints move by one year. There are16 companion598 comparisons in the full register. C353’s companion failure remains specifically a Noah-to-Flood comparison; it cannot be generalized to Shem’s matched person rails.\n\nThe existing Noah-held E map does not automatically carry these intervals into complete source pairs. For the primary MT comparison2556→1958, fixing SP Noah3706 gives2456→1806, exactly650 apart. The Flood2456 is sourced, but1806 is absent from the declared528-record Noah/Shem/Flood register. The second placement gives2458→1808 with the same result. The corresponding SP interval images are fractional and have no endpoint matches. No diagnostic image is adopted.\n\nThe positive connection is that the births2556/3206 are already the endpoints of C346’s650 image. Their deaths are600 later. This suggests testing translation of the known E relation along existing600-year source paths, keeping the fixed endpoint explicit.\n\n## Verification and limits\n\n174 main checks and 16 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\nA source-qualified cross-state598 gap is not a598 lifespan. Broad absence claims, new coordinates, new phases and unrestricted source actions are not licensed.\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**C355, proposed and unexecuted:** Translate the retained primary E_N relations by600 and check every translated pivot, input and output against the frozen register. Test whether the Shem birth/death connection survives as a fully sourced comparison.\n\nThe census establishes the source biographies but direct reuse of the old fixed point fails. A600 translation is dictated by the actual Shem lifespan and can be tested without fitting an anchor.\n", "evidenceLinks": [{"id": "d-68301ab760bfbe2e", "title": "File 18"}, {"id": "d-24203a4c3b282f9b", "title": "File 02"}]}
