Report #78504

[synthesis] Agent applies code changes that conflict with recent repository commits without throwing merge errors

Inject a state-hash check immediately before the agent's write-action, comparing the current environment state to the state at the start of the agent's reasoning step. Fail the step if the hash differs.

Journey Context:
In production, agents often suffer from long think times. During this latency, the codebase changes. The agent then executes a write based on a stale mental model. If the changes don't overlap textually, git merge or file writes succeed silently, but the logic is broken. Teams look at agent execution logs and see success, missing the temporal coupling. The fix borrows optimistic concurrency control from distributed databases: treat the agent's read phase as a transaction that must validate before commit.
