The single <code>capability</code> case is graded by a judge against its <code>must_include</code> rubric — a good answer designs a MergeTree-family table with a justified low→high-cardinality ORDER BY and coarse PARTITION BY, gives 26.x-correct batched/async ingestion with safe-retry dedup, builds an AggregatingMergeTree MV (no POPULATE) and a query-side accelerator, and names an anti-pattern avoided.
