Babysit PR

One pass surveys the PR, acts on safe mechanical work, then reports. Do not merge, close, reopen, dismiss reviews, rewrite published history, or edit PR metadata unless asked.

Preconditions and survey

Require an authenticated gh, a clean git worktree, an open PR for the current branch, and ownership of its head branch. Stop on a dirty tree rather than stashing. A merged PR is terminal; a closed-unmerged PR needs user direction.

Gather once:

• gh pr view with state, draft status, head/base refs and SHAs, merge state, review decision, check rollup, reviews, and comments;
• base divergence after fetching the base;
• inline reviewThreads through GraphQL (resolution is authoritative);
• failed/pending run details and logs.
