Implements SilvaEngine's Agent-to-Agent (A2A) protocol endpoints using the official
A2A SDK. Shared gateway dispatch, partitioning, persistence primitives, GraphQL,
serialization, async helpers, and SSE infrastructure come from silvaengine_daemon.
Authentication is handled by the gateway.
Agent handlers connect A2A tasks to core SilvaEngine agents, Hermes, OpenClaw,
goose, pi and omp. The pi and omp handlers communicate with the HTTP/SSE
sidecar in docker-a2a-gateway/pi, which runs the agent in RPC mode (pi or
omp) and retains session files for conversation resume. Queued steering and
follow-up requests leave the original
caller's run open; only its owning request closes the live session process.
See development guidance, the development plan, the long-running tasks and SSE delivery plan, and the pi integration plan, the omp integration plan.
