# The extra thing worth proving here is that `..._meta_mode` reaches every place it feeds: one
# upstream codebase serves several Meta networks, and the mode picks which. The scenario runs
# `facebook-tor` rather than the role's default, so the assertions can tell the two apart.

# It does NOT bridge anything: no Facebook or Messenger account is on the other side, and
# deliberately never will be. See docs/molecule-testing.md.
