[synthesis] AI personalization makes every user's system different, so bug reports become unreproducible and support escalations multiply

Maintain a non-personalized control cohort, log the personalization features used for each inference, and require reproduction on the exact same feature vector before classifying an issue as fixed.

Journey Context:
Traditional software ships identical binaries, so 'works on my machine' is usually a configuration issue. Personalized AI systems legitimately produce different outputs for different users based on history, embeddings, or retrieved context. This fragments failure modes: a bug may affect only users with a certain history. Support and QA must reproduce with the exact personalization state, not just the prompt.
