+For an agent driving this through separate tool calls: `cd ~` in one call does
+not reliably carry over to the next, since each call may reset to the
+project's working directory. Always `cd "$HOME"` and run the `ls-tree` (or any

+whatever the leftover cwd happens to be, which reads as "this file isn't
+tracked" when it actually is.
