v3 : socle Rust (moteur pur, accès trustinWallet, serveur) ; maquette Nuxt rangée dans maquette/

- crates/ld-engine : formule inertielle (parité avec la maquette, garde C), coquille / changement de fond, assistant d'édition à règles, composition d'un document sous vote permanent (adoptions, aperçus, rivales). - crates/trustin-access : qui voit, qui ouvre, qui gère les accès. - crates/ld-server : API axum + SQLite, connexion Ğ1 (client OAuth2 de connect.monnaie-libre.fr), invitations, entrée en vigueur automatique, signalements de contradiction, traductions éditoriales, publication git, taille de la toile lue sur la chaîne. - seeds/acte-engagement-certification.json : 33 articles, fr + en + es ; en vigueur : préambule, E1, E2 (seed a minima). - maquette/ : frontend, backend et docker v2 déplacés tels quels.
