Report #18052

[research] Agent regression suites fail unpredictably due to LLM non-determinism, leading to alert fatigue

Implement 'eval thresholds' rather than strict pass/fail. Require an aggregate score \(e.g., >85% rubric compliance over 3 runs\) to pass a PR check, and use temperature 0 for regression runs.

Journey Context:
LLM outputs vary. A strict string-match or single-run LLM-judge eval will randomly fail on CI, causing developers to ignore the suite. By running the eval multiple times and requiring an aggregate threshold, you filter out random noise and only catch genuine regressions in prompt logic or tool schemas.
