    The 7th `down_25` would go below ground — I miscounted the lift (only 6 up segments). I'll demolish and rebuild with the correct 7-segment lift and an improved closing section.

    The lift in that batch only had 5 inclines (peak z208), so one extra `down_25` would sink below the ground level. The cursor is at (65,50) z120 slope 6, so I'll flatten to z112 and continue as planned (adjusting coordinates by 1 tile).

    No active ride — clean slate confirmed. Best score banked: **6.19**. Next I'll construct the extended version (v8): 69 pieces — a 14m drop, 4 pairs of corkscrews, 2 airtime hills, banked corners, S-bends, and a double-turn closer. Full coordinate trace has been cross-checked against the catalog deltas; all tiles fit within x33–66, y30–60 (lake is to the east, avoiding x≥68).
