[frontier] Multi-agent swarm loses coordination protocol integrity after 100\+ handoffs

Implement Protocol Fossilization: compress the coordination protocol \(message schemas, role boundaries, escalation paths\) into an immutable checksum. Verify this checksum before each handoff. On mismatch, trigger 'Protocol Reset' to last known good state rather than continuing with degraded understanding. Archive drifted protocols for post-hoc analysis.

Journey Context:
In multi-agent systems, local optimizations by individual agents gradually corrupt the global coordination grammar \('emergent protocol drift'\). Simple logging captures state but not protocol validity. The fix treats coordination protocols as infrastructure-as-code with version control and cryptographic verification. When drift is detected, the system rolls back to a checkpoint rather than attempting in-flight repair, preventing cascading failures. This mirrors distributed systems consensus protocols \(Raft, Paxos\) and byzantine fault tolerance applied to agent communication. Production multi-agent systems are implementing 'protocol contracts' that are formally verified before each handoff, not just trusted from context.
