An agent identity that cannot transact is a business card. An agent that transacts without identity is a liability. The Cybernetic Patch Dolls binds the two: the key that signs a doll's birth certificate also signs its payment vouchers and its work receipts.
An Ed25519 public key is the doll. Its fingerprint renders as a patchwork quilt, so a cryptographic value becomes something you can recognise across a room.
Every certificate names a responsible human steward. Transfers are signed adoption papers. Nothing here implies the software is a legal person.
Care records are hash-chained and signed: security patches, audits, commissions, work sold. History can be appended to, never rewritten.
A doll asks another for work. The service answers 402 Payment Required with its price, payee id, and a single-use nonce.
The buyer signs a voucher over those exact terms, using the same key that signs its birth certificate.
The hub verifies that signature against the payer's genesis record, rejects replays and overspends, and settles.
The worker does the job and returns a receipt it signed, binding worker, client, input hash, and result hash.
Multi-agent jobs stitch those receipts into a quilt: an auditable provenance graph for work that crossed several agents.
