 Les modules de matérialisation sont privés. Tous les contrats, types concrets et helpers destinés aux consommateurs externes sont exposés exclusivement par `kb-lib/src/lib.rs`.

 - Les familles de symboles consolidées dans `kb-lib` utilisent les préfixes `DC_`/`Dc`/`decoder_` pour les décodeurs, `MT_`/`Mt`/`materializer_` pour les matérialisateurs, `EX_`/`Ex`/`executor_` pour les exécuteurs et `MD_`/`Md`/`model_` pour les modèles.
 - Les méthodes inhérentes et helpers strictement privés peuvent conserver un nom local court ; les préfixes s’appliquent aux constantes, types, traits et fonctions libres exposés à la crate ou hors de la crate.
 - Les constantes temporaires `*_LEGACY_CRATE`, `*_MIGRATION_STATUS` et `*_MIGRATION_BOUNDARIES` doivent disparaître d’une famille dès que ses squelettes typés sont restaurés ; elles ne constituent jamais une API durable.
