Function isNotFound

pkg/cmd/release/shared/fetch.go:296–299

isNotFound reports whether err is an API error carrying a 404 status. The release lookups treat a missing release as a sentinel rather than an error, and the api client reports the status through an HTTPError rather than through a response the call site can inspect.
