[synthesis] Why AI model performance degrades silently without triggering standard software alerts

Implement statistical process control on input feature distributions and embedding drift, rather than relying on standard SRE alerting \(like error rates or latency\) to catch model degradation.

Journey Context:
Traditional software fails loudly via exceptions or 500 errors. AI models fail silently by giving slightly worse predictions as input data drifts from training distributions. Standard SRE monitoring misses this because the system is technically 'up' and responding quickly, but the business logic is broken. You must monitor the statistical properties of the inputs and outputs, treating model serving like a manufacturing process control problem rather than a web endpoint uptime problem.
