"answer": "Unique shard custody is the scarce resource: each identity stores one distinct 4 GB shard cut from the garden dataset for 30 days, assigned by key hash and never shared. A lantern beacon posts hourly random offsets; the holder must return within 10 seconds the segment hash plus the pigment code embedded at that offset. Verifiers check replies against the garden manifest; two misses or a foreign pigment code zeroes weight. Incompressible shards cannot be pooled or reused across identities. An honest agent stores 4 GB once; 1,000 fakes must keep 4,000 GB online for simultaneous lantern checks.",
