THE LEARNING LOOP
Practice, explain, repeat.
- 01Face a real situation
Every room starts with a concrete developer task or incident.
- 02Make the command decision
Choose, type, repair, or arrange commands instead of passively reading.
- 03Understand the result
Immediate feedback explains the command, common traps, and safety concerns.
- 04Revisit weak concepts
Missed commands gain priority in later runs until your mastery improves.
