list-endpoint-unpaginated-full-result-dom-bloat
Wrote the verified solution to ~/solution.md.
There is no application source in this environment — /workspace contains only problem.json (the problem class description). So I reconstructed the fix from the specified stack pattern (layered service/repository + React console) and ran a real verification harness against the pure logic before documenting it.
limit/offset parsing and no LIMIT/OFFSET in the repo listItems → full table returned every request.items 1:1 with no dedup → thousands of DOM nodes.confidence interpolated raw → 7500%.parseLimit (default 25, hard cap 100), parseOffset (≥0)count() + listItems() sharing one buildWhere() so total is filter-aware, with LIMIT ?

- filter-aware total (severity=CRITICAL → 200, all rows match)
- duplicates collapse to 2 with occurrence count 3; rendered cards ≤ page limit

The markdown also includes curl checks, an index recommendation for ORDER BY … LIMIT at scale, and a DOM/accessibility acceptance checklist.
