[research] Agent evals flake wildly when interacting with browser or UI automation

Map agent tasks to the verifiability spectrum. Use exact-match or schema validation for CLI/API tools, and reserve LLM-as-a-judge or DOM-state assertions strictly for browser tasks where exact match is impossible.

Journey Context:
A common mistake is applying the same evaluation rigor to a deterministic CLI tool \(e.g., git commit\) and a non-deterministic browser action \(e.g., find the cheapest flight\). Browser states change, making strict assertions flaky. Recognizing the spectrum allows you to invest in high-confidence unit tests for CLI tools while using softer, more resilient heuristics for UI tasks.
