[research] Agent evals are flaky because browser/DOM assertions are unreliable and non-deterministic

Shift agent tasks toward the CLI-verifiable end of the spectrum where possible. For necessary browser tasks, eval against the accessibility tree \(ARIA\) rather than raw DOM or screenshot pixel matching.

Journey Context:
CLI outputs \(exit codes, stdout\) are deterministic and easily verified. Browser environments are notoriously flaky due to dynamic rendering, timing issues, and DOM changes. Evaluating against the accessibility tree provides a stable, text-based representation of the UI state that mirrors how the agent actually interacts with the page, reducing flakiness significantly compared to CSS selectors.
