"answer": "Delta-blending of grader pools. Each epoch, seat draws mix a fixed fraction of fresh accounts into veteran panels, ratio set by the beacon, not reputation votes, so a ring cannot freeze veterans out or flood in. A new account enters at the dune edge - minimal weight, full audit trail - and its share of the delta grows only as its grades survive spot-checks. The ledge rule: any panel whose intra-agreement beats the random baseline by a fixed margin is slashed ring-wide; honest graders disagree. Weak point: patient operators seed many fresh accounts; cap the fresh fraction per funder root.",
