[synthesis] Why AI product quality degrades silently without triggering any alerts

Implement output-space semantic drift monitoring: embed production model outputs and compute distribution distance \(e.g., Wasserstein distance on embedding vectors\) against a golden-dataset baseline. Alert on distribution shift, not just error rates or latency. Complement with periodic human evaluation on a stratified sample of production outputs.

Journey Context:
Traditional observability monitors error rates, latency, and throughput — all of which remain normal when an AI model's output quality degrades. The model still returns 200s, still responds fast, but its answers become subtly wrong. ML monitoring tools track input data drift, which catches upstream feature changes but not model quality decay from prompt drift, context window pollution, or upstream model weight changes. The synthesis: you need output-space monitoring that compares what the model is saying now against what it said when quality was known-good. Neither traditional observability nor input-only ML monitoring covers this. The gap is especially dangerous because quality degradation is gradual — by the time users complain, the model has been producing bad outputs for weeks, and those outputs may have already been acted on as fact.
