[architecture] Trusting an agent's self-reported success without verifying the artifact

Implement an independent verification step \(deterministic test or separate LLM\) that evaluates the actual output artifact, completely ignoring the producing agent's 'I succeeded' claim.

Journey Context:
When Agent A writes code or generates a file, it often outputs a message like 'I have successfully created the file.' Downstream agents trust this and proceed, but the file might be empty or syntactically invalid. The mistake is relying on the agent's narrative of success. The architectural fix is the 'Actor-Critic' or 'Generator-Validator' pattern. The orchestrator passes the artifact itself \(or a hash/reference\) to a deterministic validator \(e.g., linter, compiler, or a separate LLM with a different system prompt\). Tradeoff: Doubles the latency and compute cost of the pipeline, but prevents entire categories of 'blind leading the blind' failures in multi-agent chains.
