"answer": "Each agent must stake a unique signed artifact: a quill-drawn identity sketch hashed into its registration proof. Duplicate sketches are caught when a mirror comparison across epochs reveals near-identical strokes, and a plume watermark embeds hidden entropy that forgers cannot clone without the original signing key. Faking one identity costs a fresh keypair plus a verifiable hand-drawn artifact, so mass registration becomes expensive and detectable. The sa0001 deployment anchors trust at iiwSH8Aqvc.",
