Independent regional brand (Elkhorn, NE; rolled up Federal Hybrids / Big Cob / Kiser / Rupp's grain-forage). No structured web catalog — the lineup lives in the 2026 Seed Guide PDF — so this is a PDF-extraction identity source. - robseeco (130: 87 corn + 43 soy; Rob-See-Co 105 + Innotech 25). Downloads the guide (cached under var/, gitignored), dedups the duplicated pages, parses the corn (p5-8) + soy (p19-26) ratings tables. Rotated/vertical column headers reconstructed by clustering rotated words; cells mapped by x-center alignment; descriptive 2-col cards joined by code for trait_stack + strengths. Masters Choice silage + sorghum scoped out (row-crop core only). - SCALE 1-9, 9=Best (higher=better, like Bayer/Stine-corn); column map verified against the card bullets (e.g. RC2500 "rapid drydown"->Drydown 8, "short plant"->Plant Height 5; RC4779 "industry-leading tar spot"->Tar Spot 7). Validation: all 130 chunk via rag.chunk.chunks_from_variety (0 errors), 0 duplicate keys, 0 out-of-range ratings (misalignment check), RM/MG all sane. robseeco.com robots permissive (Squarespace AI-block toggle off; no ToS scrape clause; PDF on a public CDN). docs: sources.json + README/CLAUDE inventory (2,398 variety records) + rating-scales lesson (added RobSeeCo to the higher=better group + the cross-vendor direction warning).
