[synthesis] Multi-agent system fails silently due to corrupted shared state between agents

Implement immutable state logs \(Event Sourcing\) or copy-on-write memory for agent contexts; agents should read from a consistent snapshot and append their changes, rather than mutating a shared dictionary in-place.

Journey Context:
Shared mutable state is easy to implement. The synthesis of concurrent programming race conditions and LLM non-determinism reveals that in agents, races are common and slow, leading to persistent corrupted state that the agent then reasons over as truth. Traditional code races are fast and rare; agent races are slow and likely. The tradeoff is the complexity of event sourcing vs. the simplicity of a global dict. The right call is immutable/append-only state because debugging non-deterministic agent races is nearly impossible.
