Report #14051

[research] Agent evals are flaky because browser/DOM interactions are treated as deterministic

Separate eval suites by the verifiability spectrum. Use exact match/assertion evals for CLI and API tools. Use vision-model \(VLM\) or accessibility-tree heuristics for browser actions, accepting probabilistic pass rates.

Journey Context:
CLI outputs \(exit codes, stdout\) are deterministic; an eval can assert code == 0. Browser DOM is non-deterministic \(latency, dynamic rendering\). Treating browser evals like CLI evals leads to high false-negative rates and flaky CI pipelines. VLMs or DOM state snapshots provide a fuzzy but reliable verification layer for UI steps.
