As your image shows, the chunk in the buffer is not the chunk
navigation-begins, but the chunk navigation-begins-0.  That is
because the buffers always create a new copy of a chunk.  To get
the value of a slot of a chunk in a buffer you will first need
to get the name of the chunk in the buffer, which you can do
using one of the commands: buffer-chunk, buffer-read, or for
the goal buffer, goal-focus.
