Report #24676

[research] Treating browser/DOM agent actions as easily verifiable as CLI actions

Map agent tasks to the verifiability spectrum; use strict exit-code/stdout assertions for CLI, but require multi-modal LLM-as-a-judge or DOM-state snapshot assertions for browser tasks.

Journey Context:
CLI commands provide deterministic ground truth \(exit code 0, exact stdout diff\). Browser actions do not \(CSS changes, dynamic loading, visual layout\). Writing brittle XPath assertions for browser agents causes flaky evals. You must accept probabilistic verification \(screenshots to VLMs\) for browser tasks and reserve deterministic evals for API/CLI tasks.
