The independent QA pass.

This is what opens behind any value. A second AI — one that played no part in the research — re-reads the claim against its source and records the verdict you see here.

Asked by people who check
What happens when a source is paywalled or unreadable?
It's marked uncertain, not verified. DeepSieve researches the public web only out of the box, and a source it can't read never silently counts as confirmation.
Who owns the data if I cancel?
You do. They're your tables — export CSV/JSON or pull everything over the REST API anytime while you're subscribed, and for a year after you cancel. No annual contract.
What keeps the table current after a run?
Every paid research run includes 30 days of monitoring. After that, your plan keeps a set number of monitored runs — one per research dossier, so a large report uses several — on the per-column schedules you set; going beyond your plan bills per day, and you can stop any of them any day. While monitoring is on, an expired fact is re-checked or flagged stale, never silently trusted.
