Cited answer

abstained

The retrieved evidence does not support an answer.

An independent panel. It streams, abstains, fails or is disabled — the list never moves.

Sponsored

A band outside the numbered list. No sponsored inventory configured; payment never alters organic order.

Printed sources and index cards arranged for review on a pale-wood desk

Verification is the product, not a footnote.

Answers resolve to evidence.

Each claim is bound to retrieved results you can open. When the search gives no support, Acervo abstains instead of writing from model memory.

Every registered tier is metered.

No automatic overage. Every plan includes the result list, cited companion, all six filters and REST access.
