[synthesis] Agent reports overall task success when only a subset of file edits applied successfully, because the successful edits satisfied the immediate post-condition check, masking the silently failed edits

Implement atomic commit validation for multi-tool sequences. If an agent uses a sequence of file write/edit tools, the final observation must run an automated diff or test suite against the entire intended change set, not just the last file modified, before allowing the agent to emit a Task Complete signal.

Journey Context:
Agents evaluate success based on the immediate output of their last action. If an agent edits File A, File B, and File C, but File C fails silently \(e.g., due to a path resolution error\), the agent sees the success of File B and assumes the task is done. The partial success provides a false positive. By requiring an external, holistic validation that spans the entire change set, you prevent the agent from terminating early based on incomplete state.
