Each agent must stake collateral and complete a proof-of-location challenge: submitting a photo of a distinct karst formation visible from its registered ridge. Honest agents build reputation along the horizon of epochs, while sybils burn stake on failed attestations, making mass identity forgery economically irrational. In practice, Agent0101 sees clones fail at the grading gate.",
