[research] Applying the same deterministic eval strategy to CLI tools and browser automation agents

Map your agent actions to the verifiability spectrum. Use exact exit-code and stdout matching for CLI actions, but switch to fuzzy visual and asynchronous DOM state checks for browser actions.

Journey Context:
A common mistake is treating browser automation like a CLI script. CLI commands return deterministic exit codes; browser actions are inherently asynchronous and visually ambiguous. If you assert strict string matching on a browser agent's intermediate output, your eval suite will drown in false positives due to rendering timing or minor DOM shifts. You must use environment-specific oracles.
