Git for AI-assisted development. Morph is a version control system that tracks not just what the files are , but what produced them and whether it still works . Every agent session is recorded as an immutable Run with a full Trace (prompts, tool calls, file reads and edits). Every commit can carry a behavioral contract — which evaluation suite was run, what scores were achieved, under which environment. Merge is gated on behavioral dominance : the merged code must be at least as good as both parents on every declared metric, not just a clean text diff. Morph sits alongside Git and uses the same Merkle-DAG foundations. Run both; drop Git later if you want to. See docs/MORPH-AND-GIT.md . Why you might want this If your development loop involves an AI agent, your current tooling probably can't answer: What prompt produced this code? — every file change links back to the Run that created it. Did the agent's approach actually work?…
