Metadata

  • Commit message: feat(server): implement CleverAgents server with A2A protocol and deployment infrastructure
  • Branch name: feat/v3.8.0-server-implementation-a2a-protocol

Background and Context

Milestone v3.8.0 (M9: Server Implementation) delivers the CleverAgents server and all server-dependent capabilities using the A2A (Agent-to-Agent) protocol standard. This Legendary tracks the full scope of v3.8.0 work.

Key ADRs governing this Legendary: ADR-047 (A2A Standard Adoption), ADR-048 (Server Application Architecture).

No deadline assigned. Development effort should focus on M1-M6 milestones first.

Expected Behavior

When v3.8.0 is complete:

  • A2A JSON-RPC 2.0 wire format is implemented with _cleveragents/ extension method routing
  • A2A stdio transport (local mode) and HTTP transport (server mode) are operational
  • LangGraph Platform RemoteGraph integration enables server-side actor execution
  • FastAPI + A2A SDK server application is deployed and functional
  • Authentication and authorization (API tokens, team RBAC) are implemented
  • Entity sync via _cleveragents/sync/* extension methods works
  • Multi-device experience with shared namespaces and PostgreSQL backend
  • Server deployment via Docker + Kubernetes + Helm is operational

Acceptance Criteria

  • All three child Epics are completed and closed
  • A2A JSON-RPC 2.0 wire format is implemented
  • A2A stdio and HTTP transports are operational
  • Server application (FastAPI + A2A SDK) is deployed
  • Authentication and authorization are functional
  • Entity sync works across devices
  • PostgreSQL backend is operational
  • Docker + Kubernetes + Helm deployment is functional
  • nox passes with coverage >= 97%

Subtasks

  • Complete Epic: A2A Wire Format & Transport Layer
  • Complete Epic: Server Application & Authentication
  • Complete Epic: Deployment & Multi-Device Experience

Child Issues / Child Epics

  • Epic: A2A Wire Format & Transport Layer (v3.8.0) — #8677
  • Epic: Server Application & Authentication (v3.8.0) — #8678
  • Epic: Deployment & Multi-Device Experience (v3.8.0) — #8679

Definition of Done

This Legendary issue should be closed when:

  1. All three child Epics are fully completed and closed
  2. All acceptance criteria above are verified and checked off
  3. The v3.8.0 milestone shows 100% issue completion
  4. A release tag v3.8.0 has been created
