**How Mova uses it:** `en` trains and tests its tagger and parser on UD treebanks; the silver and bronze sets test that the grammar seeds really parse the way they describe. The training-data gate (`en::license::commercial_gate`) only accepts sources whose license allows any purpose.

**The tales split** (how Mova's tales numbers are measured): `world conllu-split mova-tales-silver-en.conllu even.conllu odd.conllu` — the odd half (1,043 sentences) is the test set, the even half (1,044) is for development; Mova's self-training splits the even half further and never reads the odd one. LAS on the odd half: 76.85 in 0.2, 77.38 in 0.3.
