  2# Working directory tracking tests for zmx.
  3#
  4# zmx learns a session's cwd from the OSC 7 the shell emits, which arrives as a
  5# percent-encoded file://<host><path> URI. That URI is what `list` reports, so
  6# the host stays visible and you can tell an SSH session apart from a local one.
  7# These tests pin that output plus the thing it depends on: the URI is decoded
  8# for the chdir, so a new session lands in a directory whose name needed
  9# escaping.
