Practice is where a large question becomes an exercise with an edge. A build can stall for many reasons; a smaller test can still show what is true, what is missing, or what needs another pass.
Nothing here is a streak or a queue to fall behind on. Each exercise earns its place by giving a live batch some evidence.
A review can be useful without becoming proof. The named source, running behaviour, and the contract behind an artifact still get the last word.
