Report #51895

[research] Agent evals are flaky because browser/UI interactions are non-deterministic

Shift evals to the CLI/API layer using deterministic mock servers or local CLI commands, and only test browser UI interactions with visual grounding as a separate, lower-confidence regression suite.

Journey Context:
Browser automation is inherently flaky due to load times, dynamic DOMs, and A/B tests. Agents interacting with CLIs or APIs return structured, deterministic exit codes or JSON. By bifurcating your eval suite into 'High Confidence \(CLI/API\)' and 'Low Confidence \(Browser\)', you avoid false negatives in CI/CD and catch real logic bugs separately from UI flakiness.
