+How to write a bot

+guarantee code indicates something you can run which will execute without errors
+if "input" refers to a valid board.

+    # (see below for more guarantees)
+
+    "whoami": "a",
+
+    # the board is by a torus by default (wraps around horiz & vert),
+    # but maps will have walls on all the edges to disable this.
+
+    # guarantee code:
