# external file updates: a write from outside pardes lands in an open pane
# that has no unsaved edits, committed like any other edit; a pane WITH
# unsaved edits keeps them and says the file changed on disk (File.changed).
#
# The writer must be a STRANGER to the editor. This script used to have a
# pardes PANE run the write, which proved much less than it looked: that
# shell's own pty output wakes the loop and paints a frame, so the reload
# could be riding on the keystroke's frame instead of on the watch. `run` is a
# child of the RUNNER — nothing it does reaches an app pty — and every
# assertion below it is a `wait`, which only READS the pty. So between the
# write and the reload the app receives no keystroke, no resize, no mouse: if
# the watch does not wake the loop by itself, these waits time out.
#
# Two files in two directories, written the two ways files actually change:
# w.txt in place (CLOSE_WRITE) and sub/s.txt by rename-over, which is what
# `zig fmt`, `git checkout` and every editor's atomic save do (MOVED_TO, and
# a new inode — the reason the mark is on the directory).
