order-by             index ordering must match ORDER BY direction or include a covering subset
join-on              index on the joined column on at least one side; FK columns are not auto-indexed in MySQL
group-by             index that allows index-scan over the group key
uniqueness-rule      add UNIQUE index only after dedup verification; allow CONCURRENT build on busy tables
