[synthesis] Why AI model rollbacks corrupt user data and break downstream systems

Implement forward-compatible data schemas and maintain N-1 model compatibility; never rely on simply reverting a model deployment artifact.

Journey Context:
In traditional software, a rollback reverts the binary and the system works. In AI, a new model might output a slightly different schema or structure \(e.g., JSON with new fields\) that downstream systems or users adapt to. If you rollback, the old model doesn't generate the new fields, breaking the UI or user workflows that now expect them. Furthermore, if the model was fine-tuned on user interactions during the rollout, rolling back loses that state. Rollbacks are actually forward migrations.
