concordance is not a valid graph (no .nodes array): {path}

This fires when a concordance file parses successfully but is not a valid graph — it has no .nodes array. The corpus atlas is a projection of the spine, and without a valid graph there is nothing to project it from.

MaybeIncorrect — build the concordance first (scripts/build-concordance.sh) before synthesizing the corpus atlas.
