[frontier] Multi-agent orchestrator bottleneck and single point of failure

Replace the orchestrator-worker pattern with ephemeral agent handoffs. Each agent receives full conversation context, executes its task, and returns a structured handoff object specifying the next agent and rationale. No persistent orchestrator maintains state between steps—the conversation history itself is the shared state.

Journey Context:
The orchestrator-worker pattern \(one boss agent dispatching tasks to worker agents\) seems natural but fails at scale: the orchestrator's context fills with worker summaries creating a bottleneck; every worker interaction requires a round-trip through the orchestrator adding latency; and the orchestrator becomes a single point of failure. The handoff pattern, pioneered by OpenAI's Swarm and formalized in the Agents SDK, makes agents peers rather than subordinates. Each agent is ephemeral—it receives context, acts, and hands off. This eliminates the orchestrator bottleneck, reduces latency \(direct handoff vs. round-trip\), and improves fault tolerance \(any agent failure only affects its segment\). The tradeoff is loss of centralized control—no single agent has a global plan view. This is mitigated by making handoff objects structured \(specifying next agent, rationale, and state updates\) and by designing agents with narrow, clear responsibilities. The pattern works best when agent boundaries align with domain or capability boundaries \(e.g., a coding agent hands off to a testing agent\).
