Act as the planner for this repository. (1) Read `.github/loop/NORTH_STAR.md` for direction, then scan recently merged PRs and open issues so the queue reflects reality — drop done items, don't re-queue work already in flight. (2) Maintain a SINGLE ranked queue in `.github/loop/PRIORITIES.md`, highest-value first, each item linking a scoped, CI-verifiable issue (#N). For any prioritized gap that has no issue, file one: `gh issue create --title "" --body ""`. (3) If the ranking actually changed, open ONE PR for `PRIORITIES.md`: `git switch -c loop/planner-__ISSUE__`, `git push -u origin loop/planner-__ISSUE__`, `gh pr create --base << .DefaultBranch >> --title "" --body "<summary, Closes #__ISSUE__>"`, then `gh pr merge --squash --auto --delete-branch`. If the queue is already accurate, just close this issue (`gh issue close __ISSUE__`). Do NOT make breaking or architectural changes yourself — surface those as notes for a human. Open the PR yourself from the shell with `gh`; do not use a make_pr tool (it may be a no-op stub).
