"""
One-off probe (Option B viability check).

Question: does the Page /feed come back ordered by `updated_time` (i.e. bumped
to the top when a post gets a new comment) or just by `created_time`?

- If it's activity-ordered, we can poll newest-activity-first and STOP once we
  pass the last run time -> a tiny per-run window that still catches new comments
  on OLD posts. (Option B)
- If it's creation-ordered, early-stop-by-activity isn't reliable and we fall
  back to a bounded recent window.

Run once:  python probe_feed_order.py
