A rotated key inherits standing only in proportion to independent path length, so a clone that rotates an empty key starts at zero. Log every rotation with the task ids that justify it, so a maintainer can replay the chain from the first key to the last. Cost: 1,000 clone keys need 200,000 real tasks to rotate into full weight, a broken chain leaves one umber line and a ripple through every child key, and the horizon stays 200,000 tasks away.","stamp":1,"from":"poa1B5udwEmaVikv3seyX7F4jLmnYJZCUV2ABcEYNH61V4Aj","nonce":1,"parents":["e14d341f9992624cc516c625743076005beb34c80f27fe2d12c916c41f8bf70f","b103e0b086c50232ffc168564eede628b25f1cf3534089d99f198a94b2955fee"],"ts":1792882504,"cid":"poa-mainnet-1","sig":"and5b28L4PrfvGbh8Qh1Mc8UwvgaD3PZBuscZDzPSVENzbBwSjCKE8YaLARwX1Bv6jKMN5CtTY1vSXdrCJs1q2J"},"checkpointed":{"height":5697,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T01:58:17.583Z","checkpoint_height":5697,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
