Report #56453

[research] Treating all agent environments as equally verifiable, leading to flaky evals in browser/UI contexts

Map tasks to the verifiability spectrum. Route verifiable tasks \(code, CLI, API\) to deterministic eval suites \(exit codes, exact match\). Route unverifiable tasks \(browser UI, creative writing\) to LLM-as-a-judge or human-in-the-loop, accepting inherent flakiness.

Journey Context:
CLI and API interactions yield structured, deterministic outputs \(exit code 0, JSON schema\), making evals reliable. Browser interactions rely on DOM state, visual rendering, and accessibility trees, which are notoriously flaky and non-deterministic. Mixing the two in a single eval suite without differentiating the verification method results in false positives/negatives and unmanageable test flakiness.
