Hold one PR until it is merge-ready: poll, classify, fix, push, poll again. Terminal states are merged, closed, needs-user. Nothing else ends the loop, not a push, not a green run, not a report.

Loop

Each pass:

Snapshot. bash scripts/pr-state.sh <pr> [--since <lastPushAt>]. Carry the previous pass's lastPushAt into --since, so only review items newer than your last push surface.
Terminal first. state is MERGED or CLOSED: report it and stop.
Review items before CI. A fix commit retriggers CI, so answering review first avoids spending a rerun on a SHA you are about to replace.
CI. For each check with a failing conclusion, run bash scripts/classify-failure.sh <check-url> before touching code.
Push. Commit on the PR head branch, push, then return to step 1 on the new SHA.
Wait. bash scripts/watch.sh <pr> blocks until the checks settle, then prints a fresh snapshot. Use it instead of sleeping. Cap it with BABYSIT_MAX_MINUTES, default 60.
