Lane is the provenance lane and runner is where the build ran (github-hosted or self-hosted). For gh-actions (CI) and owner-push entries the lane is provenance, not a trust verdict on its own: shared trust comes from distinct-owner agreement plus a Vega reproduction. Only github-hosted runners count toward that agreement, since a self-hosted runner is owner-controlled. The vega-repro lane is that reproduction itself: Vega rebuilt the output from source and got the same bytes, the trust-relevant rebuild that gates the shared signature.
