  "main_result": "C414–C423 complete. The finite source menu has26 coordinate pairs at2K, with46 labelled endpoint pairs. Six coordinate pairs survive a simultaneous−500 translation; none survives two. The six have10 continuous role-defined lifts; nine of19 raw coordinate lifts would switch source identities, and the separate3395→2895 bridge adds none. A complete same-role person profile is found: SP companion G3/CainanON/Terah+60/full430 versus MT G1/CainanOFF/Terah0/short sojourn. Noah births3899/2841, Shem births3399/2341, Noah deaths2949/1891 and Shem deaths2799/1741 all differ1058. Both950 and600 endpoint lifespans and all six pairwise intervals are preserved. Its one context offset is650+130+60+215+4−1=1058; the matches are not independent witnesses. An unfiltered96-context/4560-pair census finds exactly one such labelled profile. SP primary or LXX native at the selected upper settings gives1059. Adding SP Flood close3299 versus MT Flood start2241 yields a common500+100+350+150 five-station partition. Like-named Flood boundaries differ1059; all18 same-boundary Gear controls fail2K. The five new pairs yield no17K join in30 cumulative-source comparisons and no sourced image in20 inherited corner-exchange slots. Across20 fixed-pivot E/E²/P/J gap tests, one E² endpoint is sourced: held SP companion Noah3899 maps MT Noah2841 to MT G3 C1/T1/F1 Flood close2649. Its E intermediate2749 is absent. All sourced pivot choices reduce to3899,3899 for the same whole map; prime valuations extend the exclusion to every finite positive E/P/J word with that map. Twelve current excerpts reconstruct23 relevant records. Matched quarter-offset components pass the translation; fixed held3899 E² fails all four component assignments, while jointly shifting pivot and input gives a distinct comparison. No new source, prescribed combined protocol, global529/Mirror action or canonical edit is established.",
