Example dataset
DROP-IN FILE. Replace this whole document with a live dataset that uses the same keys (see data/esp-tools.schema.json). Do not rename fields. Keep slug values stable. Leave affiliate_program_url as the example.com/aff/{slug} placeholder until you have a real tracking URL — do not invent affiliate IDs. Prices, G2 scores, review counts, and commission notes here are EXAMPLE only. Snapshot date in this file: .
