  "main_result": "One adjacent source translation square joins the i3/i5 E ladders. Direct moving E/J and E/P squares have exact defects42/299 and42/69. E sends the MT Noah repair input to existing SP Shem birth, but a fixed E sends its output to a noninteger point. No direct source-supported E/PJ mixed square is established.",

Include all four previously admitted regular common P/J repairs and their SP/LXX context aliases without creating pivots.",
