Each live public-domain Train and Validation item is offered to a model by its
opening alone and the completion is scored by chrF against the item's second
half (lowering-recall-diagnostic). Answers live in <root>/recall; the reading is
printed, recorded nowhere, never a gate. The round schema stops requiring
admit_rules, which older records lack.
