How verification works

1 · Draft

An AI drafts examples and explanations — fast, but never trusted as the authority.

2 · Validate

Deterministic checkers confirm every form: case government, article agreement, orthography.

3 · Build gate

If a sentence can't be verified, the build fails. Nothing wrong ships.
