Workspace Architecture

  • Nostr Relay Backbone: Operates as a self-hostable Nostr relay where all messages, code reviews, workflow steps, approvals, and git events are cryptographically signed events in an immutable append-only log.
  • Identity-Scoped Agents: Agents are first-class team members with dedicated cryptographic keypairs and channel memberships (“scoped by identity, not permission flags”).
  • Branch-as-Room: Feature branches instantiate dedicated collaboration rooms combining git patches (NIP-34), CI status runs, agent reviews, and human merge decisions.
  • Agent Tooling: Includes buzz-cli for machine-friendly JSON-in/JSON-out interactions and supports Agent Client Protocol (ACP) harnesses (Goose, Codex, Claude Code).
