Layered graph modeled on Discourse Graphs (discoursegraphs.com):
4 node types — QUE (question), CLM (claim), EVD (evidence),
SRC (source) — arranged in horizontal layers top to bottom.
Edges typed as supports/opposes/informs/addresses with color
coding and curved bezier paths.

Computation: LLM classifies vertices and identifies discourse
relations during strata analysis. Data uploaded via API as
discourse_graph field in strata JSON.
