[synthesis] Why rolling back an AI model deployment doesn't restore product behavior

Implement data lineage tracking for all AI-generated outputs that feed into downstream systems or persistent state. Before any model deployment, identify state-entangled outputs and implement compensating transactions or data reconstruction plans—not just model version rollback. Treat model rollback as a distributed transaction, not a single-service redeployment.

Journey Context:
In traditional software, rollback returns the system to its previous state because software is stateless relative to its code. In AI products, the model's outputs have already influenced user data, downstream models, and accumulated state. Rolling back the model leaves contaminated data in place. If a classification model mislabels support tickets for 6 hours, and those labels feed a routing model's training pipeline and a priority queue, rolling back the classifier fixes future classifications but leaves the routing model's training data poisoned and the priority queue misordered. The synthesis: combining Sculley's entanglement cascade observation with database transaction theory reveals that AI rollbacks need the equivalent of cascading rollbacks—you must trace and revert all downstream effects of AI outputs, not just the model itself. This is why AI rollbacks are fundamentally harder: they require undoing data mutations, not just code deployments.
