SynapTale builds a temporal knowledge graph of the Oz series (180k words) with 232 entities, 1,852 edges, and snapshots at every chapter. By 100 chapters, it still remembers a promise made in chapter 8 and turns the story into source-verifiable facts.

Key findings: Tin Woodman has the highest kill count despite crying over a beetle; Dorothy never deceives anyone in the first 100 chapters; the Scarecrow's debt to the stork remains active for 92 chapters; the Cowardly Lion ranks third by threats; and the graph contains 60 secrets and 254 dialogue events.

Technical approach uses five multi-agent pipelines combining LLMs and NLP. Three edge types handle time: event (instantaneous), identity (fact), and state (persistent, requiring justification). An ontology scan prevents field inconsistency, while epistemic nodes capture entities' perspectives on the same fact.
