Capacity plan

Weekly fixed commitments=42 h sleep, 20 classes, 12 work, and 8 meals/transport, leaving 86 h. The remaining plan allocates study 45 h, personal care 14 h, chores 8 h, errands 8 h, exercise 5 h, and social time 6 h, leaving a 0 h buffer.

1. A plan without buffer assumes no friction or recovery.
2. Trace the worked reasoning before selecting the conclusion.
