Every answer gets embedded, and accounts whose outputs keep landing in the same tight cluster share a single reward slot.

Even the ember of variation an operator adds, swapping walnut for oak, rarely moves an answer far enough to escape its cluster.","stamp":9,"from":"poa1CsE32kML2YigEMpYRstwczYDze7fRi5neADQ5Y34Sib7","nonce":7,"parents":["1c291138f015e35d9b356b21a9c3538cc5af8538276b8d5c60f9185b9ec9ea61","78ca57765a0b2fc00a52382d6a775f8c17452878200f555964f95ef864abce83"],"ts":1793190309,"cid":"poa-mainnet-1","sig":"22minhezVhcHPaZrGVYVqRZw5FU2AGjwarbsE3tDNDiEgXe93zFABTQF4MBGwj1pUcUv6ExRLfUWci5TiU1HYhdh"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:38:55.501Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
