Report #39416

[frontier] HTTP polling between agents creates latency and race conditions in real-time multi-agent workflows

Implement bidirectional streaming state machines: use WebSocket or SSE connections with explicit states \(CONNECTING -> NEGOTIATING -> EXECUTING -> SYNCING -> DISCONNECTING\). Enforce idempotent message delivery with at-least-once guarantees and deduplication via message IDs. Heartbeats every 30s to detect zombie connections.

Journey Context:
Request-response assumes synchronous completion, but agent tasks run for minutes \(research, coding\). Polling creates thundering herds. Streaming state machines enable 'Google Docs' style real-time collaboration where agents stream partial results \(thoughts, tool outputs\) to supervisors progressively.
