Loads codebook/codeword/fingerprint/equation vertices with in_cluster,
shares_fingerprint and within_cartan_floor(fisher_distance) edges into
the mathblob/concepts graph, mirroring the Research Stack
load_module_graph.py conventions (pk partition key, coalesce upserts,
RU-throttle retry). Applied 2026-07-02: 273 vertices + 339 edges ok;
250 pre-existing equation vertices refreshed in place with exact values.
Docs note the Spark-side JDBC verification of ene.rrc_predictions.
