Board notes 5 details

Layout: The 8x8 board has a large brown top band, upper magenta and green pockets, cyan-blue right cells, orange and slate-blue middle pockets, a separate lower pink region, and purple lower rows; the exact row geometry is recorded in the evidence note.
Goal: Keep the seeded cow at r3c5 and follow the successful source order r2c7, r4c8, r5c2, r6c6, r7c3, r8c1, and r1c4 for eight final cows.
Opening: The opening seed is r3c5. White logical Xs are r3c1-r3c4 and r3c6-r3c7, while r3c8 remains open.
Danger Zone: Red r1c1 is the single failed brown-band tap and costs one heart; use the late brown target r1c4 instead.
Mechanics: This is an 8x8 seeded board with eight final cows; the source shows Good mid-route, then First Win after the late r8c1 -> r1c4 close, with two hearts remaining.
