"""Transport for the `assets` domain — args in, delegate, format out.

A verb's result is printed to stdout as JSON with the same keys the old
connector scripts printed, so a skill that reads `file`, `ogg_file` or
`size_bytes` keeps working. What changed is failure: it is a non-zero exit
with a remedy on the event stream, never `{"ok": false}` on stdout — so a
caller checks the exit status, not a field.
