# Validation `0.2.9` — moteur Yellowstone + standard Solana + PublicNode
> **Statut : `pre.008` est fonctionnellement verte : fmt/audit/check/tests/workspace PASS, Transport 370 unit + 47 public API + 41 completeness + 4 doctests. Clippy passe avec un unique warning `field_reassign_with_default` dans la fixture Blocks. `pre.008-fix.001` corrige uniquement ce warning ; bidi reste `pre.009`.**
> **Statut : `pre.008-fix.001` est fermée sur gate opérateur sans warning : fmt/audit/check/Clippy/workspace PASS, Transport 370 unit + 47 public API + 41 completeness + 4 doctests. `pre.009` est candidate pour le bidi standard, mutation request, Ping/Pong, backpressure, half-close et shutdown borné ; reconnect/replay restent `pre.010`.**

Le warning provient uniquement de `minimal_transaction_info()` dans `unit_tests/grpc_subscribe.rs`. `fix.001` initialise `TransactionStatusMeta.fee` directement dans le literal struct et conserve `..Default::default()`. Aucun `allow`, aucun changement runtime, aucune dépendance et aucun élargissement vers le bidi.

Les helpers protobuf qui étaient test-only jusqu'à `pre.008` sont maintenant compilés en runtime parce que `grpc_stream` les consomme effectivement. Aucun helper raw n'est public : les frontières restent `YellowstoneSubscribeRequest` et `YellowstoneSubscribeUpdate`.
Le flux sortant utilise la même `mpsc` bornée que celle fournie à `tonic::client::Grpc::streaming`; aucune queue cachée non bornée n'est interposée. Le Ping de keepalive serveur provoque une mutation ping-only actor-owned avec `id=1`, puis le Pong reste visible dans la file d'updates KSP.
`pre.009` ne tente aucun reconnect. Un half-close serveur est terminal normal ; `Status`, decode invalide et overflow sont terminaux en erreur. Le budget de reconnect, l'ordre de resubscribe, `from_slot`/ReplayInfo, gaps, duplicates et node divergence restent exclusivement `pre.010`.
**Verdict candidat :** source/fixture/audit statique prêts ; gate Cargo opérateur requis.
