Report #15224

[research] Browser automation agent evals are flaky and unreliable

Shift agent tasks from browser-based to CLI/API-based where possible to leverage deterministic exit codes and structured JSON outputs. For unavoidable browser tasks, rely on DOM state assertions rather than visual screenshot comparisons.

Journey Context:
Browser environments are inherently non-deterministic \(latency, dynamic rendering\). CLI/API tasks provide strict verifiability \(exit code 0, JSON schema validation\). Screenshot diffing for evals creates high false-positive rates due to minor rendering shifts.
