Why it surfaced

GitSim turns Git’s abstract machinery into a shared visual state: commands update the filesystem, index, references, and commit graph in real time. It offers safe practice for branching, merging, reset, revert, reflog, and Git internals without installation, an account, or consequences for a real repository.
