User flagged that Channel is expanding into their area — re-walked the cropscience.bayer.us sitemap and found 8 additional brand×crop paths beyond the original DEKALB/Asgrow/WestBred triple. Patches the scraper to walk all of them; total Bayer varieties roughly doubles from 475 to 931 and the corpus picks up first-ever coverage in sorghum (36), cotton (30), canola (6), and silage as a distinct crop (was conflated with corn before). Net new varieties: 456 Channel corn=181 soy=67 silage=54 sorghum=18 (320) DEKALB silage=82 sorghum=18 canola=6 (106) Deltapine cotton=30 (30) scrape/sources/bayer_seeds.py - Replace `BRANDS` (brand → 1 path) and `CROP_SUFFIX` (brand → 1 suffix) with a flatter `BRAND_PATHS` list of (brand, url_path, crop, is_primary_for_brand) entries. Channel and DEKALB are now multi-crop brands; the same scraper walks every brand×crop pair. - source_key derivation: for a brand's PRIMARY crop, strip the trailing `-<crop>` suffix (matches the existing deployed source keys for DEKALB corn / Asgrow soy / WestBred wheat). For SECONDARY crops, KEEP the suffix so DEKALB-the-same-SKU sold as both grain corn and silage gets two distinct source_keys (collision-safe and unambiguous for `lookup_variety`). - New `--crop` CLI filter for incremental backfills. - Log line shows brand + crop alongside source_key for visibility. rag/chunk.py - Channel + Deltapine pages use slightly different characteristics group labels (DISEASE not DISEASE RATINGS, AGRONOMIC CHARACTERISTICS not GROWTH/HARVEST, plus MATURITY / ADAPTATION / HERBICIDES / OTHER). Fold them into the DISEASE / AGRONOMIC / MANAGEMENT label sets so the chunker buckets them correctly into the standard sections. Smoke-tested cross-brand × cross-crop queries against the rebuilt index (5,529 chunks total) — all 6 sample queries surface the right brand+crop at top-3: Channel corn 110 RM → 210-25TRE BRAND Channel soy 2.5 MG IA → 2622RXF BRAND Deltapine cotton XF → DP 1820 B3XF BRAND Sorghum dryland Kansas → 6B95 BRAND (Channel) Silage corn WI dairy → DKC64-44RIB BRAND BLEND (silage variant) Canola Northern Plains → DK401TL BRAND Watchtower will pull the new image on the next push; deploy is unchanged otherwise.
