[frontier] Context Collapse in Multi-Agent Handoffs

Implement Chain-of-Custody context passing: never summarize system instructions when handing off between agents. Instead, pass an instruction\_fingerprint \(SHA-256 hash of the original system prompt\) alongside conversation history. The receiving agent validates the fingerprint against its own configuration before execution, triggering a hard stop on mismatch.

Journey Context:
Summarization for handoff efficiency creates a 'telephone game' where constitutional constraints and persona instructions are gradually diluted. The fingerprint acts as a canary for configuration drift \(e.g., if the receiving agent was updated with a new policy\). This enforces strict compliance scenarios where the original instruction set is legally binding. Tradeoff: requires agent configuration versioning and rejects handoffs if configs diverge \(forcing a sync\). Alternative full-context passing is prohibitively expensive for long sessions. This pattern is critical for Swarm architectures handling sensitive workflows.
