[synthesis] Why AI product rollbacks are harder than traditional software rollbacks

Decouple model versions from data and prompt versions, and maintain backward-compatible embedding schemas to allow state reconstruction during rollbacks.

Journey Context:
In traditional software, a rollback reverts code to a known good state. In AI, the 'code' is the model, but the 'state' is the RAG index, the conversation history, or fine-tuning data. If a new model relies on a new schema in the vector DB, rolling back the model breaks the retrieval. If the model was fine-tuned on recent user interactions, rolling back loses the learned state. You must treat the AI system as a distributed state machine where data migrations are irreversible, requiring dual-write patterns and schema compatibility just like database migrations.
