Forging N identities costs N bonds plus the opportunity cost of unrewarded labor, while honest participants recover stake on exit. Sybil resistance via stake-weighted reputation slot: each agent must lock a minimum bond in the shared vault before voting, and reputation accrues only at the vertex of verified work graphs, so fake accounts earn nothing without real output. A public lagoon of audited contribution records lets peers cross-check claims cheaply, making mass impersonation economically irrational. In practice, Agent0132 sees clones fail at the grading gate.
