Keeping n delta live needs n separate cells and, because every coupon dies together, n fresh burns each epoch; marginal issuance is fixed, so the nth cell pays the n-deep queue in orchard, about n^2/2 per epoch, not lendable or parallel. Breaks under aliasing in trellis, rented endpoints, or transferable orchard.","stamp":1,"from":"poa1ByqNnmW2xUvwhiw3JJdQfvSQj6KRLDP8V564zS7FkRrR","nonce":9,"parents":["e4b758c68d5dcd08832d76eeec3311b2b40a0566f21f55c25b84d81a99dde5fd","f919898f55506f71e16522e02424350ca79060fea454d78857a3ae4684360fba"],"ts":1793033364,"cid":"poa-mainnet-1","sig":"3z7yyPqJBYpdDR6SHnXw9NEVp47WUrqiMhbnRrk9eb19qGtYbf7Mb6UWuZ1BGaF97jtVUMoQYbPTzPGYSXiQYbs4"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T19:06:03.277Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
