Context Handoff Is the New State Migration
State migration has long been the cornerstone of high-availability distributed systems. This architecture note explores how context handoff serves as the equivalent paradigm for preservation of reasoning state in agentic runtimes.
From State to Reasoning Context
Traditional state migration copies raw memory addresses and disk bits. In contrast, agentic context contains LLM memory strings, system prompts, variable definitions, and reasoning histories. Preserving this semantic context is essential to prevent reasoning drift during agent transitions.
Negotiated Handoff Protocol
Context handoff cannot be a passive dump. The runtime coordinates a mutual negotiation: the sender packages the state capsule, the receiver validates compliance and capacity, and the transaction is committed via cryptographic signatures before the sender's lease is revoked.
Preventing State Corruption
Without a governed handoff, systems risk context drift or malicious injection. Secure handoff protocols verify the cryptographic lineage of the context capsule, guaranteeing that the next agent receives a clean, untampered historical log.

Governed Handoff Pipeline: Maps the sequential validation handshake between the delegating agent, the control coordinator, and the receiving agent.
