📜 WAYPOINT LESSON
Checkpoint: follow the path
⭐⭐ intermediate⏳ 30 min read📍 Lesson 112 of 256
A coded-cell walk with visited tracking — orientation, guards, and a loop cap.
The path walk fuses everything this module owns: decoding 10row+col, bounds guards on every jump, visited tracking, and a step cap as the sentinel against cycles that never repeat but also never end. If your first trace disagreed with the code, check whether you decoded the code as column10+row — the classic transposition.
