Three defects, all mine. Column order was ignored because organize's indexByName was keyed on the renamed display labels. Grafana keys it on the original field names, so the mapping matched nothing and the order fell back to whatever order the frames arrived in — which is why the raw line landed second. Every table is affected, not just the access one. The byte count was wrong for the NCSA sources: a trailing `pattern` capture takes the rest of the line, so `<size>` held `16 "-" "kube-probe/1.35"` rather than 16, and for nginx it swallowed the whole referer and user-agent. Replaced with a `regexp` parser bounding the capture on \d+, which also handles both line shapes — Keycloak's access line ends at the size while gunicorn's and nginx's carry more fields after it. Access log columns are now time, status, method, path, source, client, latency, bytes, raw line, with the raw record last in every table. gunicorn and nginx now share one query since their format is identical, which also halves the duplicate class names the status panel showed — one series per query returning the same class.
