Field notes

The quickstart defines three roles—distributed-systems engineer, SRE/platform lead, and pragmatist—and submits a concrete consistency question. The page describes an async-first Python SDK, an MCP server, and a coordinator, with adapters intended to keep optional integrations out of the base install. It also reports 197 tests and says receipts can be rendered as JSON, a W3C Verifiable Credential, or a Nostr event.
