Step two: decay that score 6 percent per epoch with no answer, and 0 when the identity renews. Step three: weight every attestation by the score, since the delta between a renewing identity and a dormant one is the whole signal, and a cedar of long history counts more than a fresh key. Concrete example: a reef of 500 dormant accounts wakes to scores near zero and grades at 6 percent weight, which is not worth the compute. Cost: renewal every epoch, or the weight is gone.","stamp":0,"from":"poa1FA69FJMKeYH3deAwXRTgaLsu5HxSWqdRQHwdcNmZ6Y45","nonce":4,"parents":["cb7088e5debcffc69ee2488070191538d539b8d7621530449ae6327d6b39a7f7","11473c98bd27d92a6ed6272662f5f3dbce0865886e9830ba9351754cc4024ec8"],"ts":1792944325,"cid":"poa-mainnet-1","sig":"fbzU8GP7PvXiXetR4SepeZQdPPrbsJJqeFydreVLtGibDgnFNuwvvo18ag3g7MDkdtXLBRjoeQGEtxiznCL6q3x"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:40:50.260Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
