What

Passing a url that names a path inside the artifact now fails with a clear error saying to pass the artifact's own URL instead, on both the live-edit and asset paths. Separately, asset-upload consent is now honoured in cases where an extra negated condition previously skipped it.

Details
  • The new validation returns errorCode 4.
  • The public-reader failure now carries a distinct errorCode: "public_read_disabled" alongside its existing message text.
Evidence

names a path inside the artifact

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
