new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

Webhook amount comes from the topups row, not the callback

The webhook endpoint is reachable by anyone who guesses the URL and everything it does moves money. The signature is verified against the raw body before a single field is read, in constant time. The credited amount comes from the topups row written before the provider was ever contacted — even with a valid signature, trusting the numbers in a callback turns a provider bug or a replay into a balance nobody can explain.
