Most robot demos stop at "it worked once". ClosedLoop asks what that pass is worth.

The pipeline: Muse Spark 1.3 writes a robot program from a task description. A seeded CMA-ES search looks for scenarios where it fails, and a minimizer shrinks the failure to the smallest failing case. Muse Spark proposes a repair from that case, and the repair is accepted only if it passes the failing case, a regression set, and a fresh falsifier re-run. Finally the program is certified on fresh scenarios, never used for repair, with exact Clopper-Pearson lower bounds. A camera mode judges rendered footage using SAM 3.1 and Muse Spark vision, calibrated on 700 labelled rollouts, and the bound is corrected for the judge's error rates.

We report what happened, including negative results. [Check against README.] The repaired program was certified in simulation for 8 of 16 mass-friction cells (every friction value up to about 6.25 kg). Its headline certificate (target 0.95) was refused. The certificate also refused on a heavier, lower-friction shifted distribution. Falsifier-guided repair and filmstrip feedback did not beat the baselines at our budget.

Everything is simulation only. All numbers regenerate from logs; every certificate is tied to the SHA-256 of one exact program. Open source (MIT).
