Use my brief to compare the named options for the stated purpose. Confirm the decision criteria and constraints before filling any material gap. If browsing is available, check current primary sources and save a source table with title, URL, date checked and the specific claim supported. If browsing is unavailable, use only the supplied sources and say which claims remain unchecked.

Save decision-memo.md and sources.md. The memo should include the decision, relevant criteria, a compact comparison, a conditional recommendation, risks and the next action. Separate documented facts, reasonable inferences and your judgment. State unknown access, cost or operational constraints rather than guessing. Cite claims where they are used; do not fabricate citations or treat a documentation page as proof that my account can perform the task.

Recommend only as far as the evidence supports. If a decisive unknown would change the choice, state the question and the smallest check that could settle it. Do not buy, subscribe, connect accounts or contact anyone. Return the saved files and any limits on the research.
