[frontier] Agent handoffs losing critical context in multi-agent systems

Implement context flattening protocols that serialize full agent state \(working memory, tool outputs, loop counters, and metadata\) into a structured handoff schema using JSON Schema, rather than passing simple message strings between agents

Journey Context:
Teams initially adopt multi-agent patterns \(like OpenAI Swarm\) using simple message passing, but hit production failures when Agent B needs Agent A's intermediate reasoning traces, not just final outputs. Simple dict passing loses 'episodic memory' of how conclusions were reached and critical system instructions from earlier turns. The alternative of shared global state creates tight coupling and race conditions. Context flattening treats handoffs as state serialization problems: each agent dumps its full working context \(including token counts, elapsed time, tool call history\) into a standardized schema before transfer. This decouples agents temporally while preserving full observability for debugging and allows agents to resume from checkpoints rather than restarting conversations.
