[synthesis] Concurrent agent operations corrupt shared state through interleaved mutations that neither agent detects

Implement explicit state locking or sequential gates for any shared mutable resource. Before a parallel step, identify all shared resources and either partition them \(each agent gets exclusive ownership\) or serialize access. After parallel steps complete, run a reconciliation pass that checks for conflicting mutations using diff or checksum comparison.

Journey Context:
Multi-agent frameworks allow parallel execution for efficiency, but when agents share a filesystem, database, or configuration, their operations interleave in ways that corrupt state. Agent A reads a config, Agent B modifies it, Agent A writes based on the stale read—classic read-modify-write race. The compounding effect is invisible: each agent's local view is consistent, so neither detects the conflict. The corruption propagates silently until a downstream step fails for inexplicable reasons. People try to fix this with better agent coordination prompts \('wait for Agent A to finish'\), but prompts are suggestions, not synchronization primitives. The synthesis: multi-agent parallelism is concurrent programming, but agents lack the primitives \(mutexes, compare-and-swap, transactional memory\) that make concurrent programming tractable. Prompt-based coordination is to concurrency what comments are to type safety—a documentation convention with no enforcement. The right call is to either eliminate shared mutable state \(partition resources\) or add real synchronization \(sequential gates, file locks, transactional writes\).
