[synthesis] Multi-agent handoffs cause silent state drift and hallucinated file paths

Agents must share a canonical, read-only state registry \(e.g., a directory tree snapshot\) rather than passing state via natural language. Tool calls should resolve paths against this registry dynamically.

Journey Context:
Multi-agent frameworks often treat inter-agent communication as chat. The planner says 'edit main.py', but the coder's context doesn't have the actual file tree. The coder hallucinates src/main.py vs app/main.py. Because the agents operate in isolated contexts, the partial success of creating the file masks the total failure of modifying the correct file, leading to a fragmented codebase.
