+"""download_revisit_days — how far back a tick keeps looking for EDITED posts.
+
+Operator, 2026-09-23, pointing at a Floppystack post: *"this post has been
+updated as he implements hot fixes — any chance we have a way to scan for or
+see updated posts so we can update ours to match and pull the new attachments
+and pictures etc."*
+
+A tick stopped after 20 contiguous already-have-it items. That is the right
+instinct and the wrong unit: a post edited three days after publication sits
+well below twenty seen items, so the walk turned around before reaching it. The
+walk now needs BOTH a run of seen items and a post older than this many days
+before it stops.
+
+A settings row rather than a constant (rule 25) because the right window is a
+property of the CREATOR, not of FabledCurator — one artist appends hotfix
+builds for a fortnight, another never touches a post again. 0 turns the revisit
+off entirely and restores the pure count early-out.
+
+30 days is the operator's own number, 2026-09-23.
