#5211 "Lists load as you scroll: audit, alert history, Ansible runs" (milestone 477), per preference 172. - core/paging.py: keyset paging over (time, id), newest first, with an opaque "<iso>|<id>" cursor; a page reads one row past itself to know whether another follows. No OFFSET, so rows added while someone scrolls never shift the pages after them. - _macros.html scroll_more / scroll_end and static/scroll-more.js, written once: an IntersectionObserver with a 600px margin fetches the next page before the reader reaches the end; "Loading more…" while in flight, "End of the list." at the end, and a failed page says so with a Retry button instead of re-firing on every scroll. - Audit log: no "Load more" link and no 500-row cap. - Alert history: no 200-row stop with "pick a shorter range"; alert_svc.history takes the cursor, so the MCP tool and the page share one query. - Ansible runs: no silent cap of 50.
