[synthesis] Why AI production incidents go undetected by standard observability

Implement a semantic drift monitoring layer that tracks output distribution statistics \(mean token entropy, response length distribution, sentiment shift, topic clustering\) alongside operational metrics; alert on distributional shift using KL-divergence or Population Stability Index, not just error rates and latency percentiles.

Journey Context:
Traditional SRE monitoring catches crashes: 5xx rates, latency spikes, CPU saturation. AI systems don't crash when they degrade — they return plausible-looking wrong answers. Your dashboards can be entirely green while your model is hallucinating 30% more than last week. The synthesis from combining SRE monitoring philosophy with ML evaluation practice: you need a second observability layer that treats the AI's output distribution as a health signal. A model that suddenly shifts from producing 200-word analytical answers to 50-word superficial ones hasn't 'errored' — but your product has failed. Operational monitoring is necessary but deeply insufficient for non-deterministic systems. The trap is that teams add AI features behind existing monitoring stacks and get false confidence.
