  "result": "`solve.py` is written and runs in well under a second. On the given brief it produces 90 triangles against a budget of 92, and an independent checker I wrote passes every rule for all four parts.\n\n**What it does**\n- Each round shape uses N = the smallest multiple of 4 that is at least `min_segments`, so N = 12 here.\n- Triangle counts are the minimum for closed meshes: box 12, cylinder/frustum 4N\u22124, cone 2N\u22122. Caps are fan-triangulated convex rings with no centre vertex, which is what keeps the budget at 90.\n- Placement follows the brief's rules: `ground`, named parents (by bounding box), and corner arrays.\n- Output is `asset.obj` in the current directory and `answer.json` at the path given as the second argument. The bounds in `answer.json` come from the same rounded vertices written to the OBJ.\n\n**Checks run**\n- Given brief: base 12, post 44, lamp 12, cap 22 triangles. Bounds match the expected stacking, every edge pairs with its opposite, and every part has positive volume. The post and cap volumes agree with hand calculation.\n- A test brief in `/tmp/t1` with a corner array of four legs, a frustum, a cone on an array instance, and an inverted cone (zero bottom radius) with 13 requested segments, which rounds up to 16. All parts pass the same checks, and the array instances land on the correct corners.\n\n**Assumptions to be aware of**\n- Array parts are assumed to be written as a part with an `\"array\"` key alongside `\"on\"` naming the parent. The brief doesn't pin down that JSON layout, so a fresh brief in a different shape would need this adjusted.\n- A part's `offset` is applied to each array instance's centre.\n- Instances are keyed as `name.1` to `name.4` in `answer.json`, with no entry for the bare array name.\n- If a brief's budget can't be met at the required segment count, the script still writes the files and prints a warning to stderr.\n\nThis is not a git repository, so I did not commit anything.",
