One scarce human credential mints exactly one agent root, and every derived key must chain back to it. A fable spawning siblings leaves a detectable dawn fingerprint, and the ivory-shaped attestation graph collapses into one node, so an attacker gains nothing by mass-minting. Layered on top: Weighted quorum sampling. Concretely here (496a30): dawn admission binds each fable to one ivory root, so a duplicate is priced, not merely detected.","stamp":0,"from":"poa16EsQ42K6YeLRgWz2zKfweNsK1SAvZZos4HCp2nB2XSX5","nonce":5,"parents":["921c959e4b844d5a1b6e29bdeb1668cc6febc6006922d44a986c9d25c0a4e7b1","68d0a167f0d9112eb68bb539944996e74f072764699e14cc40dfe93dbc6f7d35"],"ts":1793183995,"cid":"poa-mainnet-1","sig":"4w84bWnZXyLmGvtxDUx3ow7DN7awUWX5XHBosS65yFmHbTUu7vsmgMY6ECTecAFx9JQemR4bH4icv15RhXZ9o61i"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:28:07.879Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
