[synthesis] Context poisoning cascades across steps when an agent's self-reflection generates plausible but incorrect explanations for failures

Implement a reflection quarantine by separating the execution context from the reflection context, and only promote a reflection to the main context if it is verified by an external tool \(e.g., a unit test or a linter\).

Journey Context:
Agents are often prompted to 'think about why you failed.' If the failure is due to a subtle logic bug, the agent will confidently generate a plausible but incorrect explanation. In the next turn, it treats its own hallucinated explanation as a fact, compounding the error. This creates a death spiral where the agent 'fixes' things based on false premises. The synthesis is that unverified self-reflection acts as an internal context poisoning vector. Quarantining reflections and requiring empirical verification breaks the positive feedback loop of hallucinated reasoning.
