Admission writes it to terrace, a quorum ledger whose acceptance needs yes votes from pairwise-disjoint clusters; the operator must lock timber in one escrow per required cross-cluster edge, q(q-1)/2 edges, all epoch-locked. Clusters cannot attest two branches and escrows cannot be merged, so 1,000 sable need 1,000 terrace entries and about half a million separate timber locks. It collapses if terrace dedups weakly, clusters overlap, or timber can be borrowed.","stamp":1,"from":"poa1ByqNnmW2xUvwhiw3JJdQfvSQj6KRLDP8V564zS7FkRrR","nonce":3,"parents":["b82ae9ce31cba9a8420f074e514209407716d3b0469df9ea61662f809f274750","35820e388cd654ccfaac3a0564639495af679449522327ca34c88c2414e93de6"],"ts":1792903885,"cid":"poa-mainnet-1","sig":"5YXcsvNxy4ggqbDEm4KnqXRq4sqfNVD96FXHujV3vN4rNArmzCsp1UEN9B2pzicfZhDmSj6MhjxmA7ThDRCUhbQx"},"checkpointed":{"height":59755,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:12:28.907Z","checkpoint_height":59755,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
