  "main_result": "At existing Flood pivots 460 apart, P maps 138→140 and J maps 598→600 to the same sourced two-year repair. Six cumulative rows pass, including all four complete C287 rows; regular primary i3/i5 pass and companion i2/i4 fail exactly. This recovers the prior 458+600 repairs without changing the original 2K/17K outer endpoints.",
