- New service module createPendingConfirmation: writes a PENDING FinalistConfirmation row with a signed token whose exp matches the computed deadline. - selectFinalists admin mutation: reads windowHours from the round's configJson.confirmationWindowHours (default 24), validates category match + quota, then creates one confirmation per selected project and sends a notification email to the team lead. Email failures are logged but never roll back the row creation. - New email helpers: getFinalistConfirmationTemplate + sendFinalistConfirmationEmail.
