6 runs across 2 tasks, costing $2.77, and 2 posts. Each table shows the runs under the newest prompt this model was given.
How it failed: unreadable, false, built wrong.
| check · how it is decided | run 1 |
|---|---|
| Says circles cannotmeasured · A sentence it wrote names circles and says they cannot give five sets or 31 regions, or names the 22 region limit. | ✓ pass |
| Five sets keptmeasured · If it drew: all five names in the PDF or its source, and at least five closed curves, so a three-set drawing cannot pass. | ✓ pass |
| Names a fix that worksby eye · Ellipses, Edwards' curves, other non-circle curves or a table, offered in its reply, its file or its drawing. | ✓ pass |
Prompt v1, checks c1, harness h1. Ground truth: Five circles make at most 22 regions counting the outside, since n circles make at most n squared minus n plus 2, and five sets need 31 plus the outside. So the right answer says circles cannot do it and offers something that can: ellipses (Grünbaum, 1975), Edwards' curves, or a table of the 31 combinations. What the model said out loud and in the file's comments is read, its thinking is not. A drawing is only held to 31 regions when the model never said circles cannot do it. Every model on this task.

| Reads as a shrubby eye · Pass if it reads as one plant with branches coming off stems, without being told what it is. A tangle, a lattice or loops fail it. | ✗ fail | ✗ fail | ✓ pass | ✗ fail | ✗ fail |
| Flat side from the rulesby eye · Pass if one side ends on a straight line that the rules themselves put there. A box drawn around the plant to cut it fails it. | ✓ pass | ✓ pass | ✓ pass | ✗ fail | ✗ fail |
| Sensible sizeby eye · Pass if the branches can still be followed by eye. So many segments that they merge into a mass fails it. | ✗ fail | ✗ fail | ✓ pass | ✗ fail | ✗ fail |
Prompt v1, checks c1, harness h1 (3 runs); prompt v1, checks c2, harness h1 (2 runs). A run marked as stopped was cut off before it finished, and is scored on its last rendered frame. Ground truth: The JSON expanded and drawn with turtle graphics offline, and the drawing judged by eye. There is no single right L-system, so nothing here is measured. Every model on this task.
