[research] Treating browser automation tasks as reliably verifiable as CLI tasks

Classify tasks on the verifiability spectrum. For CLI/API tasks, use exact state diffs or exit codes. For browser tasks, rely on LLM-as-a-judge with accessibility tree snapshots rather than DOM screenshots or pixel matching.

Journey Context:
CLI commands return deterministic exit codes and standard outputs. Browser DOMs are highly variable, and visual screenshots are brittle and expensive to eval. Accessibility trees \(like ARIA DOM\) provide a structured, text-based representation of the UI state that is much more reliable for LLM evaluation than raw HTML or pixel diffs, bridging the gap between unreliable visual evals and strict DOM string matching.
