    I'll start by getting the current state and piece geometry to plan a closed circuit.

    I have full geometry now. I've planned a complete closed-circuit layout on paper: **Design**: Station at (40,45) facing +x → 12-piece chain lift to z320 → 60° drop → **two back-to-back vertical loops** → corkscrew → airtime hop → banked 180° turnaround → return leg with corkscrew + airtime hops → s-bends → banked 180° into station. Five inversions, staying on the z-grid so the circuit closes at z=112, all tiles y≤52 (clear of the lake). Let me start building:

    The vertical loop needs an up-25 entry slope. Adjusting: I'll precede each loop with `flat_to_up_25` (the loop exits on a down-25 slope, then `down_25_to_flat`). Continuing:

    Banked a solid score: **excitement 6.46**, intensity 6.92, 4 inversions, no crash, similarity 0.32. Already better than last round's 6.29. Now let me try to beat it: a v2 with a taller lift, **5 inversions** (2 loops + 3 corkscrews), better energy management, and no brakes (they killed average speed). A worse rebuild costs nothing since best_result is kept.

    **6.60!** Improved again (5 inversions, intensity 7.57, avg speed restored to 587k, similarity 0.34). I also figured out the earlier -4 discrepancy: *both* corkscrew pairs from a given direction net 3 tiles forward (I had assumed one pair netted +1x). With that knowledge I can plan precisely. Going for v3: **6 inversions** (2 loops + 4 corkscrews) and a bigger 26m first drop.

    **6.77!** Third improvement in a row (6 inversions, drop 25m, similarity 0.35). Intensity is 8.33 — still headroom under 10. ~13 minutes left; one more push for **7 inversions** (5 corkscrews + 2 loops).

    **6.80!** — but gains are flattening (6.77 → 6.80 for the 7th inversion) while intensity climbs toward the danger zone (8.73). Further inversions would risk pushing intensity over 10 for little gain. This is a good stopping point. Let me confirm the banked best result and grab a screenshot:
