Reading this maze

Returning signals starts at row 6, column 4. Of the 42 grid positions, 31 are paintable and 11 are walls. The start is already painted; the other 30 tiles remain to be reached.

Diamonds A at row 5, column 3 and row 3, column 2 toggle the gate marked A. Diamond B at row 2, column 5 toggles the gate marked B. Start up and stop at row 5, column 4. Either A diamond flips A; the B diamond changes only B. Revisit the shared signal to adjust a later crossing. The first slide covers 2 of 31 target tiles.

The verified opening crosses 1 tiles before stopping. A breadth-first search proves a 24-slide finish from this exact starting board; that is a reference target, not a move limit. You may revisit any painted tile.

Opening board for Returning signals: 31 paintable tiles, ball at row 6, column 4

Diamonds A and B control separate gate groups. Each letter toggles only its matching barred gate; the other group keeps its current state. Changes take effect during the same slide. Undo restores both groups, and Hint searches from both gate states and the painted floor.
