Report #30337

[synthesis] AI output quality degrades silently in production without triggering any alerts

Monitor output distribution statistics \(response length, sentiment scores, entity frequency, refusal rates, embedding centroid drift\) alongside traditional latency/error metrics. Alert on distributional shift, not just exceptions.

Journey Context:
Traditional software fails loudly with stack traces and 500s. AI systems fail quietly—the model still returns 200 OK, but the outputs have drifted toward uselessness. Teams relying on standard observability \(uptime, latency, error rate\) miss the degradation entirely until user complaints cascade. The key insight: you must monitor the shape of outputs, not just whether outputs occur. A model that suddenly starts giving shorter, more generic answers is failing even though no exception is thrown. Embedding-centroid drift on outputs catches semantic shifts that raw token statistics miss.
