What

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.

Details
  • 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.
Evidence

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.
