M08-L05 exercise

Starting checkpoint: CP09. Figures: SS17-05, SS18-03.

Submit the complete capstone bundle, scored rubric with evidence links, transfer result, maintenance plan, and a concise defense of four engineering decisions. Review every mandatory gate. If a gate is open, identify its exact missing evidence and next action. Do not substitute a high total score for a missing critical requirement.

Record source identity, changed files, exact commands, actual outcomes, and open limitations. Preserve the original exercise copy and review the final diff. Expected results are criteria, not evidence of execution.
