🔧 Revision Sprint Retest

Using the graded decision matrix and test evidence, teams redesign weak features such as wall shape, base support, lining, or attachment methods. After rebuilding, they complete a second critique round with nearby teams, give feedback to 2 peers, receive feedback, and revise one more time before a shortened retest with the same tools and measures. Students update their notebook with before-and-after evidence and note one trade-off created by the redesign.
