Report #79878

[synthesis] Multi-agent systems produce logically inconsistent code without throwing errors due to stale read caches

Implement vector-clock or file-modification-timestamp validation in the tool execution layer; inject a context stale interrupt if the file's mtime exceeds the agent's last read time before allowing a write.

Journey Context:
Standard distributed tracing shows successful tool calls and HTTP 200s. Teams miss that Agent A read a file at T1, Agent B modified it at T2, and Agent A wrote dependent code at T3 based on T1 state. The code runs but is logically broken. The synthesis is applying distributed systems concurrency control \(optimistic concurrency control\) to agent file system interactions, not just API calls, catching silent state divergence before it manifests as a runtime bug.
