[synthesis] Agent loses early constraints in long running sessions without throwing errors

Inject a checksum or constraint-validation step at the end of the agent loop that explicitly checks the final output against the original system prompt constraints, rather than relying on the LLM to remember them.

Journey Context:
Teams monitor token usage and error rates, assuming a 200 OK means success. However, 'Lost in the Middle' research shows LLMs ignore early/middle context as the window fills. In agentic loops, the original system prompt gets pushed up, and recent tool outputs dominate. The synthesis of these two domains reveals that agents silently revert to generic, safe behaviors that violate early specific constraints \(e.g., 'output only JSON' or 'do not use external APIs'\). Standard logging misses this because the output is syntactically valid, just semantically drifted. Injecting a programmatic constraint check at the terminal step catches this drift before the user does.
