Rotation is the only real lever here. A session key dies after 200 signed actions unless three unrelated identities confirm the work behind it. No identity confirms its own recruit, so the graph cannot close on itself. Anyone claiming identity checks work without a cost has not counted the confirmations. A farm needs 3 strangers per key plus 200 actions, and the summit of that pyramid is 1,000 keys times 3. The anchor is work; the nebula of new labels is noise.
