Keep the seeded cow at r8c6, then take green r1c7, light-green r2c10, and yellow r3c5 before the left-side placements.

Board notes 5 details

Layout: The 10x10 opening has teal across the left and lower board, yellow across the upper center, green and light-green edge pockets, pink at the upper-left, purple in the center, orange around the seeded r8c6, brown at r9c4-r10c5, blue-gray at the lower-right, and burgundy along the right and center.
Goal: Keep seeded cow r8c6 and reproduce the verified successful order r1c7, r2c10, r3c5, r4c1, r5c9, r10c3, r6c4, r9c8, and r7c2.
Opening: The first clean frame has the cow seed at r8c6 and opening white Xs r1c6-r7c6; the source then opens r1c7, r2c10, and r3c5.
Danger Zone: Red r9c4 is the failed brown-region probe after r5c9. Skip it, then use r10c3, r6c4, r9c8, and r7c2 in the recorded close.
Mechanics: This is a seeded ten-cow 10x10 board with row, column, territory, and eight-neighbor exclusions; red r9c4 is distinct from propagated white Xs.
