↗ view on GitHub · Eli Ziff · 2026-07-30 · 2919b8c1

Sets up RegLab's expert labels properly: eyecite extraction (442
distinct case citations across 208 labeled responses), CourtListener
citation-lookup + opinion cache, and claim-level segmentation via
full_span citation masking (1,704 claims, 766 with attached
citations). Records the US-materials directive in the research plan.
