[architecture] Downstream agent hallucinating verification of upstream agent output

Use deterministic, sandboxed execution environments for verification agents instead of relying on the LLM to mentally check the output.

Journey Context:
A common anti-pattern is Agent A \(Coder\) -> Agent B \(Reviewer\), where Agent B just uses LLM reasoning to say 'looks good'. This is just doubling the compute for the same flawed reasoning process. Verification must be grounded in deterministic execution. If Agent A writes code, Agent B must run it in a sandbox and check the exit code/stdout. The tradeoff is the overhead of sandbox setup and execution latency, but it provides objective ground truth that LLM reasoning alone cannot guarantee.
