Dan Kornas (@DanKornas) open-sourced MIT repo-harness: a file-backed workflow harness for Claude Code and Codex that writes plans, contracts, checks, handoffs, and review evidence into the repo, with Plan→Contract→Review lifecycle, typed hook runtime, progressive context loading, and CodeGraph — so the next session continues from project files instead of chat memory.
