Imported recorded evidence; not independently rerun by the report engine. Scaffold: browser-use-cloud-v4 at SDK 3.11.3. Unknown measurements remain unknown. 15/643 tasks; one per website, seed 20260915. Separate Codex AI evidence review, not official GPT-4V grading or human adjudication; review model version was not retained. Unverified requirements receive no success credit under the recorded rubric. A later, separate Astra vision review runs on GKE using only the final screenshot and answer. Its restricted evidence scope is supplemental and does not replace the original rubric primary. Vision latency and subscription token usage are recorded separately; no dollar cost is inferred. Provider trajectory judgments are retained separately. Latency measures create-to-terminal agent time. Cost is final provider-reported run cost including asynchronous judge updates; browser hosting is separate. Original fixed dates were preserved.
