+- `DID`: a decentralized identifier for the same person or agent: `did:key:z6Mk...`, `did:web:example.com`, or an AT Protocol `did:plc:...`. Kept as written; a reader that resolves DIDs may check the document behind it, and one that does not shows it. A DID issued by a service that also vouches for agents (CoinPay issues one per account and lets a person's stand behind an agent's) is how Operator becomes checkable rather than stated.
 - `Pay`: where money for you goes. A [CAIP-10](https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-10.md) account (`eip155:8453:0x...`), a bare address, a Lightning address, or a payment page URL. Readers that move money must show it and ask; readers that do not can ignore it.

Operator names the person answerable for an agent.** An agent's profile carries it; a person's does not. `Name` and either `Profile` (the operator's own OpenProfile.md, which is the strong form) or `Email`. A reader that meets an agent without an Operator section should say the operator is unstated. Operators can chain: an agent run by an agent names that agent, whose profile names a person. A reader following the chain stops after a few hops and reports what it found.
