X_SHOT_HOST_REFUSED
Means
x shot was asked to open a host outside the run's allow list
Typical cause
a goto to a host no allowHosts rule matches, refused before Page.navigate is sent. A request the PAGE makes to such a host is not this code — it is paused in the browser (Fetch.requestPaused), failed, and recorded in verdict.json as refused: "host"
Fix
x shot /route --allow-hosts cdn.example.com — the app's own host is always allowed
