On startup, it scans all Python files in the directory for unresolved git merge conflicts (`<<<<<<<`, `=======`, `>>>>>>>`). If any are found, it prints an `infra_stop` message and exits immediately. +- **Workflow Guard:** Before starting reviewer work, task routing checks if the MCP runtime source is mid-merge (by checking for `.git/MERGE_HEAD` or conflict markers). If dirty, it returns `infra_stop` (never `wrong_role_stop` or empty queue) to prevent unsafe mutations. +- **Recovery Instructions:** To recover from an `infra_stop` state: + 1.
