babysit-prlisted

Watch one PR and drive it toward merge **without looping forever**. Each tick reads the PR's state through the shared scripts, classifies it, and dispatches the right skill — `/fixpr` to fix recoverable blockers, `/wrap` to merge when the gate is met — then re-arms the poll until a terminal condition fires. `/babysit-pr` is a **thin orchestrator**: it never re-implements PR-state aggregation, the merge gate, fix logic, or the merge flow. It reads `pr-state.sh` + `merge-gate.sh`, and it dispatches `/fixpr` / `/wrap`. All code-verification, thread resolution, CI fixing, and merge-gate enforcement stay inside those skills (`fixpr/SKILL.md`, `wrap/SKILL.md`, `cr-merge-gate.md`). This skill only decides *which* to call and *when to stop*. This is reused by `/pr-monitor-and-manage` (issue #460): that skill invokes `/babysit-pr` per discovered PR rather than re-implementing the per-PR decision tree. ## Safety boundaries (HARD STOPS — non-negotiable, `safety.md` / #450) `/babysit-pr` is read-only plus the dispatches below. It MUST NOT: - **Never babysit a PR you did not author (issue #733, `safety.md`).** Enrolling a PR in a watch loop is a "touch". Before the first tick, gate the target with `"$PR_AUTHORSHIP_SH" <PR>` (exit 0 = yours). Not yours / undetermined → refuse with one line naming the authorship guard, and do NOT enrol — unless the user named this specific PR in chat this session (per-PR override; say you are operating under it). `polling-state-gate.sh --ensure-session
