Reference skills graph

Loaded reference nodes: not loaded. Nodes and links describe the configured reference catalogue, not a student's mastery or an empirically validated learning pathway.

Calculus 2026 has 31 topic families and 98 candidate atomic knowledge components in its versioned course package. Atomic mappings and prerequisite relationships still require educator review. This public catalogue is separate from that course mapping.

Missing catalogue attributes are unknown. Imported citations and evidence scores are withheld pending provenance review.
