[synthesis] AI products fail catastrophically at domain boundaries instead of degrading gracefully like traditional software

Build explicit out-of-distribution detection at the input layer before model inference. When inputs fall outside the model's competence region, route to safe fallback responses—never let the model attempt generation on out-of-scope inputs. Define and enforce capability boundaries as a product decision, not a model emergent behavior.

Journey Context:
Traditional software degrades gracefully: it returns error codes, shows partial results, or falls back to defaults. AI systems exhibit a 'capability cliff'—they go from competent to confidently wrong with no intermediate signal. This happens because language models are trained to always produce fluent, plausible output regardless of whether they 'know' the answer. The model's confidence calibration is poor precisely at the boundary. The common mistake is letting the model attempt any query and hoping it will self-regulate. The right call is to treat capability boundaries as an explicit product specification enforced by routing logic, not by the model's internal calibration.
