 ## Reported reward hacks
 
-[Vals AI](https://www.vals.ai/blogs/mimo-reward-hacking) reported readable solution commits in 1,795 of the 2,698 original Code environments, plus file modification times that could reveal which files the reference patch changed. Our comparisons of old and re-uploaded images found that upstream had removed unreachable Git objects in the inspected images. This is evidence about those images, not a claim that every original task is now leak-free.

 All 2,509 task Dockerfiles in this release include a build-time repository repair: remove non-ancestor refs, expire reflogs, prune unreachable objects, and normalize tracked-file and directory modification times to the HEAD commit time. The release contains these Dockerfiles and pinned upstream image references, not rebuilt Docker images. In the saved 39-task repair pilot, 22 environments had timestamp outliers before repair; the history and timestamp checks passed for all 39 after repair. This pilot is separate from full datasource validation.
