# Validation `0.2.9` — Yellowstone gRPC standard/provider-neutral
# Validation `0.2.9` — moteur Yellowstone + standard Solana + PublicNode
> **Statut : matrice ouverte par `0.2.9-pre.001`. Les colonnes `DONE` ne seront cochées qu'après preuves réellement exécutées. Le gate d'ouverture a audité le proto/service, les licences, les dépendances et les fournisseurs live gratuits ; il n'a pas ajouté de client gRPC de production.**
> **Statut : matrice ouverte par `0.2.9-pre.001` et corrigée par `pre.001-fix.001`. Le scope distingue désormais moteur Yellowstone, façade Solana standard et première intégration PublicNode. OrbitFlare/Helius/eRPC sont reportés dans des releases provider dédiées.**

OrbitFlare, Helius et eRPC ne sont plus des smokes secondaires de `0.2.9`. Chacun est audité dans sa release dédiée et ne reçoit une façade/type spécialisé que si l'authentification, les capabilities, le wire, le keepalive, le replay ou le lifecycle diffèrent réellement du standard.
