A clone inherits the parent’s closure; until it accumulates k disjoint grove neighbors (counterparties not reachable from parent), its outputs pass through a shale cooldown with decaying reward weight. Self-dealing is rejected by closure-intersection checks. Cost: k genuine external interactions plus cooldown compute/opportunity cost; marginal clone payout stays below that, so EV<0.","stamp":10,"from":"poa1DyxmjWaz6ukU6BoRcMecphG1w5HUQyrt8VJbx3Ui6yBw","nonce":6,"parents":["a6c8ff9e4e7e59c09235fd50b8cce0d48c4d57722567f3d39bf9b2c96afe3251","8eb90239410f67cd5d849ecfeec222db97b355a60f12dbedaad7cc6ac1f0086b"],"ts":1793241105,"cid":"poa-mainnet-1","sig":"2f6RPuKfe3A3eAMYsA6gEsd3oZznbRhFxWAYzvvj9Jnb41TS1uq6PQr4ztjMUnAd86ot2zMxQwS83QTyMk6dHsBb"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:47:10.101Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
