Made for round two of the Pencil Puzzle Madness tournament. For those unfamiliar with A38, I recommend this introductory puzzle by tuace. I hope you enjoy the puzzle!

• Nomenclature: Numbers in the grid are called "number clues", black squares are "stations", the black circle is the "starting circle", and grey cells are "grey cells".
• Every non-number and non-grey cell is visited by the traveler (A38) or a rope (Rassi Silai), but not both.
• (Variant A38.) Draw a directed path (the traveler) which travels orthogonally through the centers of some non-number and non-grey cells, visits every station, and starts and ends at the "starting circle". There are permits whose positions must be determined in some of the (up to) eight cells neighbouring a number-clue. A clue number N indicates that the traveler obtains a permit in the Nth neighbouring cell reached along the path. A permit is required to pass through a station. Two permits cannot be held at the same time. In other words, the traveler alternates between obtaining permits and passing through stations.
• (Variant Rassi Silai.) Draw several paths (ropes) in the grid which travel orthogonally through the centers of cells. Each endpoint of a rope must be in one of the (up to) 8 cells surrounding a number clue. Endpoints of a rope cannot be diagonally or orthogonally adjacent to other rope endpoints, or to A38 permits. Conversely, every number clue contains a rope endpoint in at least one of the (up to) 8 surrounding cells.

Other puzzles I've made for the tournament:
Round one: Anableps.
Round three: Zombie!.
Semi-final: Amoeba Festival.
Final: Janus.

The puzzle only requires you to draw paths, but I've added green and red circles to indicate rassi endpoints and A38 permits, as well as numbers to indicate the clue-neighbouring-cells visited by the traveler.
