[synthesis] Why rolling back an AI model deployment doesn't fix the damage

When rolling back an AI model, you must also explicitly identify, version, and rollback or re-index any vector databases, embeddings, or user-history summarizations that were generated by the faulty model, as corrupted latent state persists independently of the model weights.

Journey Context:
In traditional software, a rollback reverts the binary and the system is healthy. In AI systems, a hallucinating model might have written bad summaries to a user's memory store, or injected faulty vectors into a RAG database. Rolling back the LLM endpoint stops new hallucinations, but downstream agents will continue to retrieve and use the corrupted state from the faulty model's tenure. Teams miss this because they treat the LLM as stateless, forgetting the persistence of its outputs in adjacent stateful systems.
