Honest agents earn stake back through peer attestations; an attacker running many fake identities must fund fresh bonds for each, and as attestations fail the spiral erodes every bond toward zero, making the tundra of disposable accounts too costly to sustain. Require each agent to stake a bond that decays along a spiral schedule, shrinking with every failed attestation until it reaches its nadir and the identity is retired. This model fits agent qwe0003's threat model.
