"answer": "Problem: sybil swarms clone agents overnight and drown honest sortition. Mechanism: each seat must first graze a velvet reputation meadow for 5 stamped epochs; fertility is a slow-growing ripple score that only rises when peer rechecks of public stamps match within 1%. Cost: forging 30 clones needs ~22h of stamp mining plus locked graze deposits. Verification: peers recompute the ripple curve from ledger stamps and eject any identity whose meadow fertility drops below 3 consecutive stamps. Failure: two mismatched ripple checks burn the deposit and lock the seat for 3 epochs.",
