An open-source Kubernetes tool that injects reproducible faults, correlates them with probe failures, and checks infrastructure properties against defined SLAs.

Why it surfaced

heisensim gives chaos testing a deterministic lab bench: the same seed produces the same faults and results, while TOML properties turn recovery time, availability, and cascade behavior into pass-or-fail checks. Its Heisenberg-inspired framing and unusually clear experiment structure make a technical tool easy to understand at a glance.
