Report #94836

[research] Agent regression evals are flaky because they treat browser-based tasks with the same strict exact-match assertions as CLI tasks

Map tasks to the verifiability spectrum. Use strict exact-match or regex assertions for CLI/DB/API tasks where stdout is deterministic. Use LLM-as-a-judge or fuzzy matching for browser/UI tasks where DOM structure fluctuates.

Journey Context:
Browser environments are notoriously non-deterministic; a slight change in ad rendering or dynamic class names breaks brittle XPath or exact-match evals. CLI outputs \(like git status or ls\) are highly deterministic. Mixing these in a regression suite without differentiating the assertion strategy leads to either false negatives \(flaky browser tests\) or false positives \(vague CLI tests\).
