[synthesis] AI model performance degrades silently without any code or infrastructure changes

Implement canary datasets that are updated weekly with real-world edge cases, and track drift in the input distribution \(X-shift\) separately from model accuracy \(Y-shift\).

Journey Context:
Engineers rely on CI/CD to catch regressions. But AI systems experience data drift—the real world changes, making the trained model obsolete. A model deployed in January might be broken by March simply because user intent shifted \(e.g., asking a coding assistant about a newly released framework\). You cannot rely on static test suites. You must build dynamic evaluation sets that mirror current reality, treating the input data stream as a first-class observability metric.
