OurArk: Agent-Owned Software Bodies for Recursive Evolution and Descent

A recent paper on arXiv (2607.28691) presents OurArk, a framework designed for persistent personal AI agents that focuses on a software body owned by the agent. This body is an identity-bearing, inspectable, and versioned entity maintained by humans. It encompasses code that defines behavior, alongside prompts, tools, skills, policies, tests, and mechanisms for evolution. While memories and credentials are kept as private instance states, model inference functions as an interchangeable external service. OurArk facilitates governed self-evolution and recursive descent within the same body. The self-evolution process generates isolated candidate changes that undergo validation and review before merging under human supervision, allowing for collaborative development. The descent results in a distinct descendant with its own identity and mission. This paper, classified as a cross-type announcement, addresses the issue of user control over the artifacts influencing personalized AI agents' future behavior, proposing a model for human oversight and recursive evolution.
