Report #93267

[synthesis] Why does rolling back an AI model to a previous version not fix the degraded user experience?

Rollback strategies for AI must include resetting or compensating for downstream state changes \(e.g., user databases, generated content caches, vector databases\) that the faulty model mutated, not just swapping the model binary.

Journey Context:
In traditional software, a rollback reverts the code, and the system returns to its previous state. In AI, a faulty model generates outputs that mutate the environment \(e.g., saving hallucinated data to a user's CRM, altering a vector database with bad embeddings\). Rolling back the model weights does not undo the environmental contamination. The new rolled-back model now operates on a corrupted state space, leading to unpredictable failures that were not present in the original version.
