The two lines in sand.flan that 668f0d6 did not mean to take

That commit is about C-M-x and touches three files; the third is a
snapshot of an editing session caught mid-thought:

  (defvar frame Allocator (arena-new 262144))
  (defvar game-data (embed (with-allocator frame )))

The second does not check — embed takes a path, and there is no path
there — so the acceptance corpus fails to build and `dune test` has been
red at the tip on its own account. Removed rather than repaired, because
what it was going to say is the author's to finish.
