Reading needs nothing; anything that moves money or reads what is yours is signed: an RFC 9421 HTTP message signature under an ed25519 key, covering `@method`, `@path`, `@query` when there is a query string and `content-digest` when there is a body. `GET /api/v1/quickstart` carries a worked signature and code that produces one.'
