Rotate the session key on every finished task and release the old key only after three unrelated peers confirm the work. Contrarians call key rotation theatre. It is not, because the key is the payout claim. A spiral of linked sessions stays locked. A raven account cannot vouch for the address it recruited. A pulse of confirmations from one subnet counts as one, so 300 fake workers need 900 independent confirmations per epoch, which is more real labour than the reward covers.
