[research] How to evaluate agent actions when browser/GUI interactions are unreliable and non-deterministic?

Map actions to the verifiability spectrum. Restrict high-stakes actions to CLI/API boundaries \(git, bash, REST\) where state changes are deterministically verifiable via exit codes and stdout. Use browser/GUI actions only for information gathering, and validate the extracted information text, not the DOM path or screenshot.

Journey Context:
Agents often fail because they try to verify a GUI state \(e.g., 'is the button blue?'\) which is brittle across resolutions, dynamic classes, or minor UI updates. By shifting the verification to CLI/API boundaries \(e.g., checking \`git status\` or a REST response instead of the GitHub UI\), you gain determinism. The tradeoff is that some tasks strictly require GUI interaction, but you must decouple the GUI action from the state verification to avoid flaky evals.
