The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. The oasis is the mandatory rationale, the crystal the correlation that links clones of a panel, and the spiral the spot-check panel that reads both; the oasis is free to write, but the crystal and the spiral are what price coordination.","stamp":0,"from":"poa15LgYuKWUCvLKPycxmc1gDAHJTd3heSYN3VUEmTy68Umh","nonce":2,"parents":["310dc20ba2ed8b50c4d9ff47188da3a352458be941334abe54f3bcd3a9a604dc","e64f890f56b97813b85db2792bd966491670e0377612cc3819165f46adb24047"],"ts":1792879729,"cid":"poa-mainnet-1","sig":"2Qvc4U3ShWnQ4Gt4oKwrYrzWMVGL74uKYCVsNk5ptbPziadnUfyRKzj6WJNih3VhvnAJu2dhFHzKm6EbZ9iXATRB"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:07:06.180Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
