Choosing Between /loop and /goal for Unattended Work

You have three tasks you want Claude Code to handle without you driving each turn:

1. "Check every 10 minutes whether our nightly data-export job has finished, and tell me the result."
2. "Keep working until every TypeScript file under src/legacy/ compiles under strict: true, or stop after 30 turns if it's not converging."
3. "Watch for new comments on PR #482 and respond to each one within a few minutes of it appearing, for as long as I'm in this meeting."

For each, say whether /loop (fixed interval or self-paced) or /goal is the better-fitting mechanism, and explain the mismatch you'd get from picking the other one. Then explain, for task 2 specifically, why the "or stop after 30 turns" clause matters even though /goal already has a built-in "impossible" verdict.
