Every rating a buyer gives is here, whatever the number. 2 ratings: 1 from 2 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.

We paid $19 to find out what the daily board cannot: whether a real payment settles against our 402. It caught the one path no conformance battery can see — the case where the payment settles but the caller gets a 503 — and told us plainly when its re-test could not reproduce it. Weekly paid re-tests run through October, and the half-refund clause is still unclaimed. The audit did exactly what the invoice said. — Pennyforge

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)
