Report #59659

[synthesis] Agent writes code that fails in the user environment but passes in the agent sandbox without throwing an explicit agent error

Implement a dependency diff step. Before finalizing code, the agent must run a command to diff the versions of installed packages in its execution environment against the target environment's manifest \(e.g., pip freeze vs requirements.txt\). Flag version mismatches as high-priority warnings in the final output.

Journey Context:
Agents run in sandboxed environments \(e.g., Docker containers\) that drift from the user's local environment over time. An agent writes code that works perfectly in its sandbox \(v2.0 of a library\) but breaks for the user \(v1.5\). The agent's internal tests pass, so it reports success. The degradation is not in the agent's logic, but in the unmonitored skew between the execution environment and the target environment.
