${ISSUE_BODY}

Create your branch from this GitHub issue, then run /slfg to implement it end-to-end. The PR must reference \"Closes #${ISSUE_NUM}\".
You are running autonomously in a ralph-loop — when you have clarifying questions, ask them and then answer them yourself using your best judgment based on the codebase, existing patterns, and docs. Document any key assumptions in the PR description.
If you hit an unresolvable blocker, create a draft PR documenting it."
