Step 7 of 10 in the C354–C363 authorization.\n\n**The joined source mapping selects primary b=2, but leaves the cumulative choice a unresolved.** In the20 fixed C319 controls, six algebraic endpoint images are exact; only four have complete source membership:02:i3/i5 and22:i3/i5. Requiring the separate17K condition retains22:i3/i5, as before.\n\nLet e=1 for the SP companion and0 for primary. The two input legs are460−e and600+e−b. Relative to the actual matched SP Shem birth/death, the generated endpoint errors are:\n\n- Birth error: `(25/23)e`.\n- Death error: `(300b+25e−600)/299`.\n\n| Rail and regular choice | Birth error | Death error |\n|---|---:|---:|\n| Primary b2 |0 |0 |\n| Primary b0 |0 |−600/299 |\n| Companion b2 |25/23 |25/299 |\n| Companion b0 |25/23 |−575/299 |\n\nThe companion b2 total is close to1100 because two errors partly cancel. Its birth endpoint is still wrong, and its death endpoint misses by25/299. Neither rounding nor transferring a companion to MT is permitted. These fractions are comparison residuals, not calendar residues or adopted dates.\n\nThe two algebraically exact but unadmitted controls occur at the edge of the existing source domain. They do not supply new Gear4 endpoints or missing cumulative members.\n\nWithin this menu the construction is equivalent to the primary regular2K requirement. Its gain is a concrete source interpretation of that side as a two-segment path to the SP Shem biography. It does not prove the independent cumulative selection or a textual prescription to join the ratios.\n\n## Verification and limits\n\n83 main checks and 15 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\nThe menu result restates the regular side criterion and does not independently selecta. Near numerical cancellation does not repair endpoint identities or source membership.\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**C361, proposed and unexecuted:** Place the600 and650 output branches in the matched SP/MT Shem birth/death rectangle. Check the resulting1250 source span and whether the existing Noah-held double-E comparison translates to a fully sourced Shem-held endpoint comparison.\n\nThe joined map now has clear control limits. Its600 lifespan output and the earlier650 cross-tradition output share a starting Shem node; their relation may expose a source-backed connection to the retained1250 double expansion.\n"}
