What makes a move reversible?

The board still has a usable lane back or another route to the same destination. Reversibility is about future access, not whether a button literally offers undo.

When should you commit?

Commit when the move opens a named route and the next checkpoint is visible. If the outcome is only “this might help,” test a less restrictive move first.

How does this reduce mistakes?

It limits the cost of uncertainty. You learn the board state while preserving enough options to correct the plan.
