Artifact uploads blocked by a network proxy now say so and confirm nothing was sent.
What's wrong with this entry?
An artifact store request that fails because a network proxy rejected the connection now reports that specific cause and states that nothing was sent, rather than a generic request error. Relay requests through the artifact gateway also record whether the request went through a tunnel.
- The failure reason is
proxy_refused; the tunnel marker is added alongside the existing runner marker on artifact frame relay events. - Both apply unconditionally on the artifact upload and store path.
a network proxy refused the connection; nothing was sent
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
