[frontier] Multi-agent delegation suffers intent drift where sub-agents return results that violate original constraints

Implement a 'mandate checksum' protocol: the parent agent generates a compressed 'intent hash' \(3-word mnemonic \+ constraint digest\) that every sub-agent must echo back in its response header; if the hash deviates, the parent rejects the result and re-delegates with the original mandate.

Journey Context:
In multi-agent systems \(AutoGen, CrewAI, MetaGPT\), Agent A delegates to B, which delegates to C. By the time C returns to B and B to A, the task has subtly changed—parameters loosened, constraints dropped \(e.g., 'use Python 3.11' becomes 'use Python'\). This is the 'telephone game' of multi-agent systems. Simple 'chain of thought' logging doesn't prevent drift because each agent interprets the previous agent's summary through its own context. The checksum protocol forces every agent to acknowledge the original immutable constraints, not just the immediate predecessor's version. It's similar to a Merkle tree for intent. Production implementations treat the checksum as a 'receipt' that must match for the transaction \(delegation\) to complete. Trade-off: token overhead for the hash and verification logic vs. delegation integrity.
