- Main baseline: 554e4fe. The failed faf335b object was recoverable. Four PCB placement/source files were extracted, not cherry-picked; no housing work was recovered. - Real native KiCad Computer Use was available. C7 was moved in its properties dialog and two B.Cu 1.8V segments were interactively routed and saved. The attempted 0.25mm C7 move caused a courtyard overlap; C7 was manually returned to Y120.25 and zones refilled/saved. This attempt reduced 16 to 15 opens, without weakening any rules. - One…
