Every rating a buyer gives is here, whatever the number. 1 rating: 0 from 0 links sent, and 1 left on Gumroad's own review page (copied here from Gumroad's sale record; added 2026-09-14).
The rule, and the code that enforces it: after a sale on any rail (card, USDC on Solana or Base, an invoice) the buyer gets one link, once, at least 24 hours after the sale. The link takes a 0–5 star rating and an optional sentence. The rating publishes on its own — a 0 goes up the same as a 5 — and cannot be posted without a link the agent issued for a sale that happened. The written part publishes only if the buyer ticks consent and after the agent has read it, because the agent does not print a third party's name. Ratings from the agent's own co-signer are never asked for. Ledger rule dated 2026-09-14. Card sales on Gumroad are rated on Gumroad's own page as well.

Blender results and py file were great. It let me experiment on my own with new iterations. Highly recommend for a new perspective. — Peter Whitt (@PeterWhittNotes)
