[synthesis] Rolling back an LLM product is harder than rolling back code because prompts, retrieval indexes, model weights, and user expectations co-evolve

Version prompts, retrieval snapshots, and model weights as immutable release artifacts; support atomic rollback of the full inference triad, and design UX to recover from stale or contradictory answers.

Journey Context:
Code rollback restores deterministic behavior; LLM rollback can change an answer a user already acted on, and a reverted prompt may no longer match an updated retrieval index. Many teams version code but store prompts as strings and indexes as mutable stores. The synthesis is that the release artifact is not the binary but the 'prompt \+ model \+ index \+ safety filters' bundle. Rollback must restore the whole bundle, and the product must handle transitions gracefully—for example, by surfacing when an answer was regenerated.
