[synthesis] Why CI/CD breaks for non-deterministic AI systems

Replace deterministic assertions with statistical bounds checking in CI/CD. Use 'eval harnesses' that run the model against a golden dataset and assert that metrics remain within an acceptable confidence interval, rather than expecting exact matches.

Journey Context:
Traditional CI/CD assumes that if tests pass for a given input, the output is correct. AI models are non-deterministic; the same input can yield different outputs, and minor prompt changes can cause cascading failures. Combining software engineering \(CI/CD\) with ML evaluation \(eval harnesses\) shows that treating AI models like deterministic code leads to flaky tests and false confidence. The fix is to shift from 'does it pass?' to 'is the distribution of outputs acceptable?'.
