Report #88145

[research] Agent regression tests fail intermittently due to LLM non-determinism, breaking CI/CD pipelines

Replace deterministic assertions \(assert x == y\) with statistical regression thresholds \(e.g., score must be >= 0.85 over 5 runs\) and use embedding distance or LLM grading instead of exact string match for expected outputs.

Journey Context:
LLM outputs vary with temperature, top\_p, and underlying model weight updates. Running a single execution in CI/CD will inevitably result in flaky builds. The industry standard shift is towards evaluating the distribution of outcomes. A regression is not a single failed run, but a statistically significant drop in the success rate across a sample of runs.
