Published in the ACM Digital Library on September 27, 2026, pages 126-135. The paper codes 13 proof-of-completion requirements across 779 eligible public bounty listings using two independent coders and blinded adjudication. It reports that 56.2% meet its author-defined severe threshold and that those listings span 154 distinct requirement combinations. The requester-label comparison is explicitly post hoc and cluster-sensitive: a hypothesis for a preplanned follow-up, not a confirmed group difference. Location proof itself was less common among agent-or-bot-labeled listings (2.8% versus 11.7%). Sole author: framing, coding scheme, corpus audit, analysis, and manuscript.
