 # Changelog KSP
 
+## 0.3.12 — Yellowstone + hydration HTTP + continuité de run du Worker RawTransaction — 2026-09-09
+
+`0.3.12` ouvre la première source réseau productive de `ksp-worker-raw-transaction-ingest-lib` sans remettre en cause la fondation source-neutral de `0.3.11`. Le Worker dépend désormais de la façade `ksp-onchain-transport-lib` mais reste sans Config, Job Backfill, backend Store physique, `reqwest`, `tonic` ou proto provider direct. `RawTransactionIngestRuntimeResources` reçoit une source Yellowstone caller-composed et un pool HTTP cohérent ; `start` conserve la fondation sans source, tandis que `start_with_runtime_resources` lance la verticale live supervisée.
+
+Les updates Yellowstone `Transaction`, `TransactionStatus` et les transactions incluses dans `Block` sont projetées vers des signaux source-neutral, coalescées de manière bornée par `(network, signature, commitment)`, hydratées via `getTransaction` observed puis converties par `ksp-raw-transaction-lib` avant admission/persistence Store. `BlockMeta` et `Slot` restent continuity-only. La provenance composite conserve les identités logiques sûres de la source et de la route d’hydration, sans URL, secret ni payload distant. Les gardes réseau/signature/slot/index/commitment empêchent les croisements de matériau avant admission.
+
+La release matérialise une processing frontier strictement run-local : le Worker distingue travail pending/settled, n’avance jamais au travers d’un pending plus ancien et compacte ses états sans revendiquer une preuve de complétude durable. Le reconnect/replay reste Transport-owned : `from_slot` et `SubscribeReplayInfo` ne sont pas pilotés par le Worker. Le Worker projette un état source-neutral `Active/Reconnecting/Closing/Closed/Failed`, compte reconnect/replay-attempt/continuity-gap et fault avec `source_failed` lorsqu’une hausse du gap Transport prouve que la rétention ne permet plus la reprise demandée. Aucun Backfill ou repair automatique n’est déclenché.
+
+Le hardening final ferme les duplicate storms, saturation/coalescence, Store lent/fautif, stop/fault pendant hydration/reconnect, overflow de compteurs, abandon des pending sans faux `settled`, abort/join des tâches privées et absence de retry HTTP possédé par le Worker. `pre.010` ajoute les canaris cross-layer Transport -> Worker -> Common RAW -> Store et verrouille les dependency firewalls, fixtures Legacy/V0, redaction et inventaires publics.
+
+Le gate déterministe `pre.011` passe rustfmt check, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, `cargo test --workspace --all-targets --all-features`, les suites ciblées et les trois inspections Cargo demandées. Les smokes live keyless HTTP Devnet et WebSocket Devnet sont exécutés séparément et passent ; les smokes Yellowstone token-gated et le Worker end-to-end Yellowstone + HTTP + Store restent explicitement non exécutés faute de ressources fournies, sans faux PASS. `pre.012` réconcilie ensuite README/USAGE et les architectures concernées avec cette verticale réellement matérialisée.
+
+La suite reste découpée : `0.3.13` ajoute WS standard, Helius `transactionSubscribe`, HTTP live polling et la convergence multi-source ; `0.3.14` ferme le gap repair/hardening multi-source. `prompts/032-V0_3_13_START_PROMPT.md` ouvre `0.3.13` uniquement depuis le tag stable `v0.3.12` et impose un `pre.001` d’audit/sizing avant toute extension productive.
+
+## 0.3.11 — Fondation runtime source-neutral du Worker RawTransaction ingest — 2026-09-08
+
+`0.3.11` introduit `ksp-worker-raw-transaction-ingest-lib` comme premier Worker concret KSP pour l’acquisition continue de `RawTransaction`, tout en fermant volontairement la release **sans source réseau productive**. La crate consomme `ksp-worker-api`, `ksp-raw-transaction-lib` et la seule façade `ksp-store-lib`; elle ne dépend ni de Config, ni d’un Job, ni d’un backend Store physique, ni encore de `ksp-onchain-transport-lib`. Son identité stable est `raw_transaction_ingest`, ses settings bornent la capacité d’admission, la concurrence de persistence et la deadline de drain, et son `start` utilise exclusivement le runtime Tokio actif fourni par le caller.
+
+Le runtime possède un supervisor privé, des tâches source/persistence détenues, une admission centrale `mpsc` bornée avec backpressure, la canonicalisation/assembly Common RAW, une observation key déterministe et la persistence atomique en mode `Normal`. Les outcomes distinguent insert, idempotence et tombstone purgée ; un contenu divergent devient `worker_raw_transaction_ingest.content_conflict`, les erreurs Store restent classifiées sans texte distant, et aucun provider gagnant n’est choisi implicitement. Les snapshots concrets latest-value se projettent directement sur `WorkerSnapshotSource`, utilisent séquences/compteurs checked et conservent le terminal pour les lecteurs tardifs.
+
+Le hardening final ferme les races stop/fault, les source failures, la saturation observable, le Store lent/fautif et le shutdown borné. À l’expiration de `shutdown_drain_timeout`, le Worker ferme les admissions, abort les tâches restantes, les rejoint toutes puis publie `drain_timeout`; aucune tâche privée ne survit au terminal. Les tests externes de hardening/release verrouillent les sept codes d’erreur publics, les huit modules de production, les vingt-quatre exports crate-root, la redaction, le dependency firewall et l’absence de surface historique/Backfill/Transport/Config/backend direct.
+
+Le gate technique final `pre.011` passe rustfmt check, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, 56 tests Worker, `cargo test --workspace --all-targets --all-features`, les arbres Cargo Worker normal/features et `cargo tree --duplicates`. La réconciliation `pre.012` ajoute ensuite les README/USAGE durables du Worker et réaligne l’architecture sur l’état matériel : la fondation `0.3.11` n’a aucun adapter HTTP/WS/Yellowstone productif, aucune API publique d’enqueue/source registration et aucun replay/gap-repair live.
+
+La trajectoire live reste découpée : `0.3.12` ouvre Yellowstone transactions/blocks/status + hydration HTTP + continuité de run, `0.3.13` ajoute WS standard/Helius/HTTP live et la convergence multi-source, puis `0.3.14` ferme le gap repair/hardening multi-source. `prompts/031-V0_3_12_START_PROMPT.md` ouvre `0.3.12` uniquement depuis le tag stable `v0.3.11`; son `pre.001` doit réauditer les surfaces Yellowstone/Solana/provider actuelles, l’injection Transport, l’hydration, le frontier, `from_slot`/ReplayInfo, les smokes accessibles et le sizing avant toute implémentation lourde.
+
+## 0.3.10 — Lower-layer RAW Transaction commune + qualification cross-source — 2026-09-08
+
+`0.3.10` introduit `ksp-raw-transaction-lib` comme lower-layer source-neutral commune aux producteurs `RawTransaction`. La canonicalisation RAW v1 auparavant locale à `ksp-job-backfill-lib` est extraite sans modifier les golden bytes/hash existants ; le Backfill consomme désormais cette common crate sans créer de dépendance vers un Worker. La bibliothèque construit les modèles `RawTransaction`/`RawTransactionObservation` de `ksp-store-api`, conserve l'identité canonique `(network, signature)`, borne et redacted les entrées hostiles, et reste volontairement sans Transport, Config, runtime async, Job, Worker ou backend Store physique.
+
+La common matérialise également un wire Solana source-neutral Legacy/V0/V1 avec sérialisation Base64 et extraction de signature depuis le matériau transactionnel complet. La représentation V1 couvre header, compiled instructions, configuration V1 et signatures terminales ; les gardes structurelles rejettent les états non supportés plutôt que d'inventer une compatibilité. `ksp-onchain-transport-lib` ajoute `get_block_observed`, qui conserve l'identité sûre de la route réellement gagnante tout en réutilisant la validation `getBlock` existante.
+
+Les preuves cross-source ferment explicitement ce qui est qualifié et ce qui exige encore hydration. Un `blockSubscribe` standard `full/base64` peut produire le même RAW v1 qu'un `getBlock` HTTP sur le sous-ensemble déterministe prouvé. Helius `transactionSubscribe` reste un signal nécessitant hydration HTTP lorsque `blockTime`/version manquent. Yellowstone qualifie le wire Transaction V1 et la conservation du `block_time` dans Block, mais `Transaction` nécessite hydration pour le temps de bloc et le chemin Block complet reste conservateur tant que l'identité byte-for-byte entre meta protobuf et meta JSON HTTP n'est pas prouvée. Aucun RAW-direct Yellowstone complet ni feed EARLY n'est revendiqué sans preuve.
+
+Le gate technique final `pre.007` passe les audits Rust/Markdown, `cargo check --workspace`, Clippy workspace/all-targets/all-features avec `-D warnings`, `cargo test --workspace --all-targets --all-features`, les suites ciblées common/Transport/Backfill et les graphes Cargo demandés ; les smokes live opt-in restent ignorés conformément à leur contrat. La réconciliation `pre.008` aligne ensuite la terminologie durable des couches Store sur `D1 RAW -> D2 STRUCTURAL -> D3 DECODED -> D4 DOMAIN`, réserve `N1–N4` aux niveaux architecturaux et complète `README.md`/`USAGE.md` de `ksp-raw-transaction-lib`. Son gate opérateur repasse format, audits, `cargo check --workspace` et Clippy strict sur `0.3.10-pre.8`.
+
+Le runtime concret a été volontairement retiré de `0.3.10` après recalibrage du sizing. La trajectoire devient `0.3.11` fondation runtime/persistence déterministe, `0.3.12` Yellowstone + hydration/continuité, `0.3.13` WS standard/Helius/HTTP live + convergence multi-source, `0.3.14` gap repair/hardening/smokes, `0.3.15` Desk d'ingestion et `0.3.16` extension Backfill multi-source. Le Job historique paramétré et le Worker continu restent des producteurs indépendants du même Store.
+
+`prompts/030-V0_3_11_START_PROMPT.md` ouvre `0.3.11` uniquement depuis le tag stable `v0.3.10`. Son `pre.001` doit auditer la base réelle, le graphe de dépendances, le runtime/supervision, les bornes de channels, la persistence/déduplication déterministe, les snapshots et le dimensionnement avant toute implémentation lourde ; aucune source live complexe n'est requise pour fermer cette release.
+
 ## 0.3.9 — Worker API générique + audit exhaustif d'acquisition RawTransaction — 2026-09-05
 
 `0.3.9` introduit `ksp-worker-api` comme façade générique, courte et runtime-neutral pour services continus. La surface stable reste Core-only et expose `WorkerId`, `WorkerKindCode`, `WorkerState`, `WorkerHealth`, `WorkerActivity`, `WorkerLifecycle`, `WorkerStopToken`, `WorkerSnapshotSequence`, `WorkerSnapshot`, `WorkerSnapshotFuture` et `WorkerSnapshotSource`. Les identités sont bornées et redacted, le lifecycle possède des transitions explicites avec terminaux immuables, le stop token est partagé/idempotent, la séquence ne wrappe pas et le snapshot source latest-value reste object-safe, `Send + Sync` et implémentable depuis l'extérieur. L'API ne possède aucun runtime `start/stop` universel, aucune sémantique Job/checkpoint, aucun domaine Solana et aucune dépendance Transport/Store/Config/Tauri.

 # ksp-job-backfill-lib
 
 `ksp-job-backfill-lib` implémente le premier job historique concret de KSP : un backfill borné de transactions Solana vers la couche RAW durable.
 
-La crate compose les contrats Job, Transport observé et Store backend-neutral sans posséder leurs politiques internes. Elle couvre l'admission, la découverte historique, l'hydratation `getTransaction`, la conversion RAW v1, la persistance atomique, la concurrence bornée, la frontier contiguë, le checkpoint caller-owned, l'annulation coopérative et les snapshots latest-value.

+`getBlock` possède également une forme bare-encoding legacy séparée et deprecated. Pour les consumers qui doivent conserver la provenance exacte d’un pool multi-endpoint, `get_block_observed(...)` exécute la même forme moderne et retourne la valeur typée avec le nom sûr de l’endpoint et le provider réellement gagnants après sélection/retry/reroute. Cette projection n’expose ni URL, ni headers, ni body HTTP brut. Une réponse RPC `null` reste `None` dans la valeur observée.
+
+Lorsque `transactionDetails = full` et `encoding = base64`, chaque `SolanaBlockTransaction` conserve le transaction wire Base64, `meta` et `version`. Le consumer peut alors projeter ces DTOs vers sa couche métier sans faire dépendre Transport d’une canonicalisation RAW particulière. Les valeurs Economics restent celles du runtime : le consumer ne doit pas supposer localement un taux d'inflation ou un minimum de délégation constant.

+# ksp-raw-transaction-lib
+
+`ksp-raw-transaction-lib` fournit la lower-layer KSP source-neutral commune aux producteurs de `RawTransaction`.
+
+La crate transforme un matériau transactionnel complet déjà acquis en représentation RAW canonique KSP, fournit les primitives de parsing de signature et de sérialisation wire Solana nécessaires aux voies qualifiées, puis permet d'associer la transaction canonique à une observation/provenance possédée par le producer.
+
+Elle ne possède aucun Transport, Config, Job, Worker, runtime async, Store runtime ou backend physique.
+
+## Responsabilités
+
+La façade crate-root expose quatre familles de contrats.
+
+### Canonicalisation RAW Transaction
+
+- `RawTransactionMaterial` ;
+- `RawTransactionWireField<T>` pour préserver distinctement omission, `null` explicite et valeur ;
+- `RawTransactionVersion` ;
+- `canonicalize_raw_transaction` ;
+- `RAW_TRANSACTION_FORMAT_ID` et `RAW_TRANSACTION_FORMAT_VERSION`.
+
+La canonicalisation produit un `ksp_store_api::RawTransaction` avec payload KSP déterministe et SHA-256 de contenu. Le producer reste responsable de fournir un matériau source-neutral complet ; la crate n'effectue aucune I/O réseau.
+
+### Signature Solana
+
+- `parse_raw_transaction_signature` valide et décode une signature Base58 bornée vers exactement 64 bytes ;
+- `format_raw_transaction_signature` encode exactement 64 bytes canoniques vers la forme Base58 bornée correspondante ;
+- `extract_raw_transaction_signature_from_binary_base64` extrait la première signature canonique d'un wire transactionnel Base64 complet ;
+- les bornes textuelles publiques permettent l'admission avant décodage.
+
+Les diagnostics ne recopient pas la signature hostile.
+
+### Wire transactionnel source-neutral
+
+La surface `RawSolana*` représente et sérialise les messages transactionnels Solana Legacy, V0 et V1 nécessaires à la common RAW :
+
+- `RawSolanaMessageVersion` ;
+- `RawSolanaMessageHeader` ;
+- `RawSolanaCompiledInstruction` ;
+- `RawSolanaAddressTableLookup` ;
+- `RawSolanaTransactionConfig` ;
+- `RawSolanaTransactionMessage` ;
+- `RawSolanaTransactionWire` ;
+- `serialize_solana_transaction_wire` et `serialize_solana_transaction_wire_base64`.
+
+Cette surface est un contrat de wire commun, pas un decoder Program et pas une façade Transport.
+
+### Acquisition canonique + observation
+
+`assemble_raw_transaction_acquisition` associe une transaction canonique à :
+
+- une `RawObservationKey` déterministe possédée par le producer ;
+- une `RawAcquisitionProvenance` sûre possédée par le producer.
+
+Le résultat `RawTransactionAcquisition` contient exactement une entité canonique et une observation liée. Il ne persiste rien lui-même.

+
+Le graphe normal reste limité à `ksp-core-lib`, `ksp-store-api`, `base64`, `serde_json` et `sha2`.
+
+## Relation avec STRUCTURAL
+
+Cette crate appartient à **RAW**. Elle ne réalise pas la décomposition Store D2 `RAW -> STRUCTURAL`. La future couche STRUCTURAL consommera le RAW persistant et le décomposera en unités Solana génériques plus fines avant tout décodage Program.

+
+# Utilisation de ksp-raw-transaction-lib
+
+Cette page décrit la façade publique durable de `ksp-raw-transaction-lib`. Les consumers utilisent uniquement les exports du crate-root.
+
+## Parser une signature transactionnelle
+
+Lorsqu'une source fournit une signature Base58 textuelle, la convertir avec le parser commun plutôt que de dupliquer le décodage :
+
+```rust
+fn parse_signature(value: &str) -> ksp_core_lib::Result<ksp_store_api::RawTransactionSignature> {
+    return ksp_raw_transaction_lib::parse_raw_transaction_signature(value);
+}
+```
+
+Le résultat contient exactement 64 bytes canoniques. Les entrées vides, hors bornes, Base58 invalides ou de longueur décodée incorrecte sont rejetées sans recopier la valeur hostile dans l'erreur.
+
+Lorsqu'un consumer possède déjà les 64 bytes canoniques et doit appeler une API textuelle Solana, utiliser l'encodeur commun plutôt que d'implémenter Base58 localement :
+
+```rust
+fn format_signature(value: &ksp_store_api::RawTransactionSignature) -> std::string::String {
+    return ksp_raw_transaction_lib::format_raw_transaction_signature(value);
+}
+```
+
+Le texte produit respecte les bornes publiques de signature et effectue un round-trip exact avec `parse_raw_transaction_signature`.
+
+Lorsqu'un wire Base64 complet contient déjà son tableau de signatures, utiliser :
+
+```rust
+fn embedded_signature(value: &str) -> ksp_core_lib::Result<ksp_store_api::RawTransactionSignature> {
+    return ksp_raw_transaction_lib::extract_raw_transaction_signature_from_binary_base64(value);
+}
+```
+
+## Construire et sérialiser un wire Solana source-neutral
+
+Le producer peut projeter son DTO Transport/protobuf vers les types `RawSolana*`, puis utiliser le sérialiseur commun. Exemple V1 minimal :
+
+```rust
+fn serialize_v1() -> ksp_core_lib::Result<std::string::String> {
+    let message = ksp_raw_transaction_lib::RawSolanaTransactionMessage::new(
+        ksp_raw_transaction_lib::RawSolanaMessageVersion::V1,
+        ksp_raw_transaction_lib::RawSolanaMessageHeader::new(1, 0, 0),
+        vec![[1_u8; 32]],
+        [2_u8; 32],
+        vec![ksp_raw_transaction_lib::RawSolanaCompiledInstruction::new(0, vec![0], vec![3])],
+        vec![],
+        std::option::Option::Some(ksp_raw_transaction_lib::RawSolanaTransactionConfig::default()),
+    );
+    let wire = ksp_raw_transaction_lib::RawSolanaTransactionWire::new(vec![[4_u8; 64]], message);
+    return ksp_raw_transaction_lib::serialize_solana_transaction_wire_base64(&wire);
+}
+```
+
+Pour Legacy ou V0, choisir `RawSolanaMessageVersion::Legacy` ou `V0` et fournir uniquement les éléments admis par cette version. Le sérialiseur valide les invariants structurels avant de produire les bytes.
+
+`RawSolanaAddressTableLookup` représente les lookups V0. `RawSolanaTransactionConfig` représente la configuration inline V1 ; le cas explicite où toutes ses options valent `None` reste sémantiquement présent.
+
+## Construire le matériau RAW canonique
+
+Une fois le wire transactionnel Base64 et les métadonnées source-neutral disponibles, construire `RawTransactionMaterial`. Les états wire doivent conserver la différence entre champ absent, `null` explicite et valeur :
+
+```rust
+fn material(
+    network: ksp_store_api::RawNetworkId,
+    signature: ksp_store_api::RawTransactionSignature,
+    transaction_base64: std::string::String,
+) -> ksp_raw_transaction_lib::RawTransactionMaterial {
+    return ksp_raw_transaction_lib::RawTransactionMaterial::binary_base64(
+        network,
+        signature,
+        42,
+        std::option::Option::None,
+        transaction_base64,
+        ksp_raw_transaction_lib::RawTransactionWireField::Omitted,
+        ksp_raw_transaction_lib::RawTransactionWireField::Value(ksp_raw_transaction_lib::RawTransactionVersion::Legacy),
+        ksp_raw_transaction_lib::RawTransactionWireField::Omitted,
+    );
+}
+```
+
+Pour une source où la signature doit être extraite du wire lui-même, `RawTransactionMaterial::binary_base64_with_embedded_signature` évite un second parser producer-owned.
+
+## Canonicaliser vers RawTransaction
+
+La canonicalisation est déterministe pour un même matériau complet :
+
+```rust
+fn canonicalize(
+    material: ksp_raw_transaction_lib::RawTransactionMaterial,
+) -> ksp_core_lib::Result<ksp_store_api::RawTransaction> {
+    return ksp_raw_transaction_lib::canonicalize_raw_transaction(material);
+}
+```
+
+La crate :
+
+- canonicalise les sous-arbres JSON significatifs ;
+- conserve les états omission / `null` / valeur ;
+- construit le payload au format KSP RAW Transaction ;
+- calcule son SHA-256 ;
+- applique les bornes communes avant construction du modèle Store.
+
+Elle ne persiste pas la transaction et ne choisit aucune politique de retry, endpoint ou source.
+
+## Associer l'observation du producer
+
+Le producer construit sa provenance avec les types Store API, puis assemble l'entité et l'observation :
+
+```rust
+fn acquisition(
+    transaction: ksp_store_api::RawTransaction,
+) -> ksp_core_lib::Result<ksp_raw_transaction_lib::RawTransactionAcquisition> {
+    let provider = match ksp_store_api::RawProvenanceCode::new("example") {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    let protocol = match ksp_store_api::RawProvenanceCode::new("solana.http") {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    let method = match ksp_store_api::RawProvenanceCode::new("get_transaction") {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    let received_at = match ksp_store_api::RawTimestamp::from_unix_millis(1_700_000_000_000) {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    let provenance = ksp_store_api::RawAcquisitionProvenance::new(
+        provider,
+        protocol,
+        method,
+        ksp_store_api::RawAcquisitionOrigin::Live,
+        received_at,
+    );
+    return std::result::Result::Ok(ksp_raw_transaction_lib::assemble_raw_transaction_acquisition(
+        transaction,
+        ksp_store_api::RawObservationKey::new([7_u8; 32]),
+        provenance,
+    ));
+}
+```
+
+La clé d'observation doit être déterministe selon la politique du producer. Plusieurs sources peuvent produire des observations différentes pour la même identité canonique `(network, signature)`.
+
+## Persister depuis un Job ou un Worker
+
+La common crate ne dépend pas du Store runtime. Le lifecycle host concret récupère les deux parties puis appelle la façade Store appropriée :
+
+```rust
+let (transaction, observation) = acquisition.into_parts();
+// Le Job/Worker concret transmet ensuite transaction + observation à ksp-store-lib.
+```
+
+Ne pas introduire `ksp-store-lib`, Transport, Config, Job ou Worker dans `ksp-raw-transaction-lib` pour simplifier cet appel. La direction de dépendance reste du producer vers la common RAW, puis du producer vers le Store runtime.
+
+## Frontière avec STRUCTURAL
+
+Ne pas utiliser cette crate pour décoder des Programs ou pour produire directement des unités STRUCTURAL. Son résultat reste D1 RAW. La décomposition `RAW -> STRUCTURAL` appartient à une couche ultérieure et réutilise le RAW durable comme input.

+Le Worker reste indépendant de Config et de tout backend Store physique. Le caller compose les ressources Transport et Store, puis les remet à la crate par ses façades publiques.
+
+## Pipeline productif actuel
+
+La première verticale live est :
+
+```text
+Yellowstone standard subscribe
+    -> Transaction / TransactionStatus / Block
+    -> signal source-neutral (network, signature, slot, commitment, provenance sûre)
+    -> coalescence bornée par (network, signature, commitment)
+    -> HTTP getTransaction observed
+    -> ksp-raw-transaction-lib
+    -> admission centrale bornée
+    -> ksp-store-lib
+    -> RawTransaction + RawTransactionObservation
+```
+
+`BlockMeta` et `Slot` ne produisent pas de RAW directement. Ils servent uniquement à la projection de continuité du run.
+
+La qualification reste conservative : même lorsqu'une update Yellowstone contient une transaction complète côté protobuf, le Worker hydrate actuellement les signaux transactionnels par HTTP `getTransaction` avant de construire le RAW canonique. Il n'existe donc pas de second canonicaliseur Yellowstone.
+
+## Contrat de source Yellowstone + HTTP
+
+`RawTransactionIngestYellowstoneSource::new` reçoit :
+
+```text
+YellowstoneGrpcChannel
+YellowstoneSubscribeRequest
+HttpTransportPool
+HttpRoleName d'hydration
+```
+
+La construction est sans I/O et refuse notamment :
+
+- une requête Yellowstone invalide ;
+- l'absence de famille porteuse d'ingestion ;
+- un commitment `Processed` ou implicite ;
+- un réseau Yellowstone non représentable ;
+- une provenance provider/endpoint non représentable ;
+- l'absence d'une route HTTP compatible pour `getTransaction` sur le même réseau.
+
+Le runtime-resource aggregate public contient exactement une source Yellowstone validée. Il n'expose ni enum provider, ni collection de sources, ni callback, ni queue d'enqueue, ni client inférieur.
+
+## Runtime et lifecycle
+
+Le Worker s'exécute sur le runtime Tokio courant du caller. Il ne crée pas de runtime global et n'expose aucun `JoinHandle` public.
+
+`RawTransactionIngestHandle` permet de :
+
+- demander un stop coopératif et idempotent ;
+- lire une source de snapshots concrets latest-value ;
+- utiliser la même source via `WorkerSnapshotSource` ;
+- attendre le terminal après drain et join des tâches possédées.
+
+Le shutdown est borné par `shutdown_drain_timeout`. Les tâches source, hydration et persistence possédées sont drainées ou abort+join avant publication terminale. L'abandon terminal d'une hydration retire son pending run-local sans le convertir artificiellement en travail `settled`.
+
+## Admission, coalescence et backpressure
+
+La queue centrale est un `tokio::sync::mpsc` privé borné par `admission_queue_capacity`. Les sources internes subissent la backpressure ; aucune queue non bornée ni silent drop n'est autorisé.
+
+La source Yellowstone possède également un coordinateur d'hydration borné :
+
+```text
+in-flight hydration <= persistence_concurrency
+pending source signals <= 65_536
+```
+
+Les signaux partageant le même `(network, signature, commitment)` sont coalescés avant le fan-out HTTP. Les provenances utiles restent néanmoins conservées pour les ingress produits après hydration.
+
+Les retries/reroutages HTTP appartiennent à `ksp-onchain-transport-lib`. Le Worker ne possède pas une seconde boucle de retry autour de `getTransaction`.
+
+## Processing frontier run-local
+
+Le snapshot expose :
+
+```text
+hydration_pending
+processing_frontier_slot
+oldest_pending_slot
+```
+
+Cette frontier mesure uniquement le traitement des signaux réellement observés pendant le run courant. Elle n'est ni un checkpoint durable, ni une preuve de complétude blockchain, ni un curseur de Backfill.
+
+Un signal transactionnel devient pending après validation de sa clé d'hydration et insertion dans le coordinateur. Il devient settled pour la source lorsque :
+
+```text
+getTransaction -> Missing
+ou
+getTransaction -> Available puis ingress envoyé avec succès vers l'admission centrale
+```
+
+Un `BlockMeta` ou `Slot` continuity-only est settled localement sans produire de RAW. La frontier n'avance jamais à travers le plus ancien pending connu.
+
+## Reconnect, replay et continuité
+
+Le reconnect/replay Yellowstone appartient à Transport. Le Worker n'écrit pas `from_slot` et n'interprète pas directement `SubscribeReplayInfo`.
+
+Le snapshot Worker projette uniquement des informations sûres :
+
+```text
+source_state
+source_reconnect_total
+source_replay_attempt_total
+source_continuity_gap_total
+```
+
+`RawTransactionIngestSourceState` distingue :
+
+```text
+Active
+Reconnecting
+Closing
+Closed
+Failed
+```
+
+Un replay attempt n'est pas une preuve de replay réussi ni de continuité parfaite. Si Transport augmente son compteur de continuity gap parce que la borne de rétention prouve que le slot demandé n'est plus rejouable, le Worker classe la source en failure et termine avec `worker_raw_transaction_ingest.source_failed`.
+
+Le Worker ne lance alors ni Job Backfill ni campagne historique automatique.
+
+## Persistence Store
+
+La persistance passe exclusivement par `ksp-store-lib` avec `default-features = false`. Aucun backend physique n'est importé directement.
+
+L'écriture utilise le mode normal atomique `RawTransaction + RawTransactionObservation`. Les outcomes distingués incluent :
+
+```text
+entity inserted
+entity already present
+entity skipped purged
+observation inserted
+observation already present
+observation not recorded for purged entity
+content conflict
+store failure
+```
+
+Un content conflict est terminal et n'est jamais converti en succès idempotent.
+
+## Snapshots et erreurs
+
+`RawTransactionIngestSnapshotSource` est latest-value : les lecteurs peuvent rater des transitions intermédiaires mais récupèrent toujours la dernière projection complète et monotone.
+
+Les codes Worker publics sont :
+
+```text
+worker_raw_transaction_ingest.settings_invalid
+worker_raw_transaction_ingest.runtime_invalid
+worker_raw_transaction_ingest.store_failed
+worker_raw_transaction_ingest.content_conflict
+worker_raw_transaction_ingest.counter_exhausted
+worker_raw_transaction_ingest.source_failed
+worker_raw_transaction_ingest.drain_timeout
+```
+
+Les diagnostics et `Debug` ne recopient pas de payload RAW, signature, URL, credential, filtre provider, texte backend/provider arbitraire ou client inférieur.
+
+## Dépendances
+
+Les dépendances normales sont exactement :
+
+```text
+ksp-core-lib
+ksp-logging-lib
+ksp-onchain-transport-lib
+ksp-raw-transaction-lib
+ksp-store-lib (default-features = false)
+ksp-worker-api
+sha2
+tokio (macros, rt, sync, time)
+```
+
+La crate ne dépend pas de Config, Job, `ksp-store-api` directement, backend Store concret, `reqwest`, `tonic`, `yellowstone-grpc-proto` ou Tauri.
+
+## Hors périmètre
+
+La verticale actuelle ne possède pas :
+
+- plusieurs sources productives simultanées dans `RawTransactionIngestRuntimeResources` ;
+- source WS/Helius-specific ou HTTP polling Worker ;
+- sélection Config interne au Worker ;
+- checkpoint persistent de processing frontier ;
+- campagne de réparation historique automatique ;
+- application Desk ou process autonome ;
+- décodage STRUCTURAL/DECODED/DOMAIN.
+
+Les futures extensions doivent conserver la séparation avec `ksp-job-backfill-lib` et réutiliser les mêmes contrats Common RAW/Store.

+# Utilisation de ksp-worker-raw-transaction-ingest-lib
+
+Cette page décrit la façade publique de `ksp-worker-raw-transaction-ingest-lib`. Le caller possède la composition du runtime Tokio, du `Store` et des ressources Transport ; le Worker ne lit pas Config, ne construit pas un backend physique et ne lit pas de secret depuis l'environnement.
+
+## Construire les settings
+
+Les identités sont validées par leurs couches propriétaires :
+
+```rust
+fn worker_settings() -> ksp_core_lib::Result<ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestSettings> {
+    let network = match ksp_store_lib::RawNetworkId::new("mainnet") {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    let worker_id = match ksp_worker_api::WorkerId::new("raw-ingest-mainnet-0001") {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    return std::result::Result::Ok(ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestSettings::with_defaults(network, worker_id));
+}
+```
+
+Le Worker kind est fixe :
+
+```rust
+assert_eq!(ksp_worker_raw_transaction_ingest_lib::RAW_TRANSACTION_INGEST_WORKER_KIND_CODE, "raw_transaction_ingest");
+```
+
+Pour des limites explicites :
+
+```rust
+let settings = ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestSettings::new(
+    network,
+    worker_id,
+    512,
+    16,
+    std::time::Duration::from_secs(10),
+);
+```
+
+Bornes publiques :
+
+```text
+admission_queue_capacity   1 ..= 65_536      défaut 256
+persistence_concurrency    1 ..= 64          défaut 8
+shutdown_drain_timeout     100 ms ..= 30 s   défaut 5 s
+```
+
+Une valeur hors borne retourne `worker_raw_transaction_ingest.settings_invalid` avec uniquement le nom stable du champ invalide.
+
+## Choisir le mode de démarrage
+
+### Fondation sans source productive
+
+`RawTransactionIngestWorker::start(settings, store)` démarre la fondation runtime sans source Transport. Ce mode reste utile aux tests/compositions qui veulent uniquement le lifecycle, les snapshots et le contrat de shutdown.
+
+```rust
+let handle = match ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestWorker::start(settings, store) {
+    std::result::Result::Ok(value) => value,
+    std::result::Result::Err(error) => return std::result::Result::Err(error),
+};
+```
+
+### Source Yellowstone productive
+
+Pour l'ingestion live, le caller compose d'abord les ressources via les crates propriétaires, puis construit :
+
+```rust
+fn runtime_resources(
+    yellowstone_channel: ksp_onchain_transport_lib::YellowstoneGrpcChannel,
+    subscribe_request: ksp_onchain_transport_lib::YellowstoneSubscribeRequest,
+    http_pool: ksp_onchain_transport_lib::HttpTransportPool,
+    hydration_role: ksp_onchain_transport_lib::HttpRoleName,
+) -> ksp_core_lib::Result<ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestRuntimeResources> {
+    let source = match ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestYellowstoneSource::new(
+        yellowstone_channel,
+        subscribe_request,
+        http_pool,
+        hydration_role,
+    ) {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+    return std::result::Result::Ok(ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestRuntimeResources::new(source));
+}
+```
+
+Puis :
+
+```rust
+let handle = match ksp_worker_raw_transaction_ingest_lib::RawTransactionIngestWorker::start_with_runtime_resources(
+    settings,
+    store,
+    runtime_resources,
+) {
+    std::result::Result::Ok(value) => value,
+    std::result::Result::Err(error) => return std::result::Result::Err(error),
+};
+```
+
+Les deux entrées exigent un runtime Tokio courant et un `Store` portant exactement le même `RawNetworkId` que les settings. Le démarrage avec ressources exige également que la source Yellowstone/HTTP cible ce même réseau.
+
+## Préparer la source Yellowstone
+
+La `YellowstoneSubscribeRequest` doit :
+
+- être valide selon Transport ;
+- contenir au moins une famille transaction-bearing admise par le Worker ;
+- utiliser explicitement `Confirmed` ou `Finalized` ;
+- rester compatible avec le réseau du `YellowstoneGrpcChannel`.
+
+Le `HttpTransportPool` doit posséder au moins une route compatible avec le rôle d'hydration et `getTransaction` sur le même réseau. La construction de `RawTransactionIngestYellowstoneSource` vérifie ces invariants sans ouvrir la connexion réseau.
+
+Le caller ne passe pas de signature, `program_id`, plage de slots ou limite historique au Worker. Ces paramètres appartiennent à un Job Backfill, pas au service continu.
+
+## Comprendre la pipeline live
+
+Les familles Yellowstone sont traitées ainsi :
+
+```text
+Transaction       -> signal -> HTTP getTransaction -> Common RAW -> admission
+TransactionStatus -> signal -> HTTP getTransaction -> Common RAW -> admission
+Block             -> un signal par transaction -> HTTP getTransaction -> Common RAW -> admission
+BlockMeta          -> continuity-only
+Slot               -> continuity-only
+Account/Ping/Pong/Entry -> sans RAW Transaction dans cette verticale
+```
+
+Les signaux de même `(network, signature, commitment)` sont coalescés avant l'hydration HTTP. Le Worker ne possède pas une boucle de retry HTTP : reroutage/retry/backoff restent dans `ksp-onchain-transport-lib`.
+
+## Observer le snapshot concret
+
+```rust
+let source = handle.snapshot_source();
+let current = source.current();
+
+let sequence = current.worker_snapshot().sequence();
+let state = current.worker_snapshot().state();
+let queue_depth = current.admission_queue_depth();
+let in_flight = current.in_flight_persistence();
+let hydration_pending = current.hydration_pending();
+let frontier = current.processing_frontier_slot();
+let oldest_pending = current.oldest_pending_slot();
+let source_state = current.source_state();
+```
+
+Pour attendre une valeur plus récente :
+
+```rust
+let observed = source.current().worker_snapshot().sequence();
+let newer = source.wait_for_change(observed).await;
+assert!(newer.worker_snapshot().sequence().is_after(observed));
+```
+
+Le flux est latest-value : les transitions intermédiaires peuvent être coalescées. Ne pas l'utiliser comme journal exhaustif.
+
+## Utiliser la projection Worker API
+
+La même source implémente `ksp_worker_api::WorkerSnapshotSource` :
+
+```rust
+let source = handle.worker_snapshot_source();
+let current = ksp_worker_api::WorkerSnapshotSource::current(&source);
+let observed = current.sequence();
+let newer = ksp_worker_api::WorkerSnapshotSource::wait_for_change(&source, observed).await;
+assert!(newer.sequence().is_after(observed));
+```
+
+La projection commune contient seulement les dimensions génériques Worker. Les compteurs et frontiers spécifiques restent sur `RawTransactionIngestSnapshot`.
+
+## Lire les compteurs
+
+```rust
+let snapshot = handle.snapshot_source().current();
+
+let admitted = snapshot.admitted_total();
+let canonicalized = snapshot.canonicalized_total();
+let persisted = snapshot.persisted_total();
+let inserted = snapshot.entity_inserted_total();
+let existing = snapshot.entity_already_present_total();
+let purged = snapshot.entity_skipped_purged_total();
+let observations = snapshot.observation_inserted_total();
+let conflicts = snapshot.content_conflict_total();
+let store_failures = snapshot.store_failure_total();
+let source_failures = snapshot.source_failure_total();
+let backpressure = snapshot.backpressure_wait_total();
+let reconnects = snapshot.source_reconnect_total();
+let replay_attempts = snapshot.source_replay_attempt_total();
+let proven_gaps = snapshot.source_continuity_gap_total();
+```
+
+`admission_queue_depth()`, `in_flight_persistence()` et `hydration_pending()` sont des gauges latest-value. Les compteurs cumulés ne wrapent jamais silencieusement ; l'épuisement est terminal avec `worker_raw_transaction_ingest.counter_exhausted`.
+
+## Interpréter la processing frontier
+
+`processing_frontier_slot()` est la plus haute slot de travail source réellement observé qui n'est pas bloquée par un pending plus ancien connu. `oldest_pending_slot()` expose ce plus ancien pending lorsqu'il existe.
+
+Cette frontier est strictement run-local :
+
+```text
+elle ne prouve pas que toutes les transactions blockchain d'une slot ont été observées
+elle ne prouve pas la persistence durable des ingress déjà envoyés à l'admission
+elle n'est pas persistée entre deux runs
+elle n'est pas un checkpoint Backfill
+```
+
+Un `Missing` HTTP règle le signal du point de vue source-processing sans créer de RAW. Un ingress `Available` n'est réglé qu'après envoi réussi vers l'admission centrale. Une hydration abandonnée au shutdown est retirée des pending sans faire avancer artificiellement la frontier.
+
+## Interpréter reconnect et replay
+
+`source_state()` peut retourner `Active`, `Reconnecting`, `Closing`, `Closed` ou `Failed` après démarrage de la source productive.
+
+Les compteurs ont des sémantiques distinctes :
+
+```text
+source_reconnect_total       reconnects automatiques réussis observés
+source_replay_attempt_total  tentatives de reconnect portant une demande de replay
+source_continuity_gap_total  gaps de rétention prouvés par Transport
+```
+
+Une tentative de replay n'est pas une preuve de continuité. Le Worker ne choisit pas `from_slot` et ne traite pas directement `SubscribeReplayInfo` ; ces mécanismes appartiennent à Transport.
+
+Si `source_continuity_gap_total` augmente, le Worker fault avec `worker_raw_transaction_ingest.source_failed`. Il ne déclenche pas automatiquement `ksp-job-backfill-lib`.
+
+## Demander un stop et attendre le terminal
+
+```rust
+let accepted = handle.request_stop();
+let terminal = handle.wait_terminal().await;
+
+match terminal {
+    std::result::Result::Ok(state) => {
+        assert!(state.is_terminal());
+    }
+    std::result::Result::Err(error) => return std::result::Result::Err(error),
+}
+
+if accepted {
+    // La première demande de stop a été remise au runtime vivant.
+}
+```
+
+`request_stop()` est idempotent. Le terminal n'est publié qu'après le drain borné et la récupération des tâches possédées.
+
+## Interpréter les faults
+
+```text
+settings_invalid      settings techniques hors contrat
+runtime_invalid       invariant runtime/lifecycle impossible
+store_failed          erreur Store non-conflict classifiée
+content_conflict      contenu canonique incompatible avec l'identité durable
+counter_exhausted     compteur/séquence monotone arrivé à sa borne
+source_failed         source/replay/hydration terminée par une erreur classifiée
+drain_timeout         drain de shutdown hors deadline
+```
+
+Un consumer doit traiter l'`ErrorCode` comme contrat stable et ne pas dépendre d'un texte backend/provider arbitraire.
+
+## Composition supérieure
+
+Le pattern attendu est :
+
+```text
+Config / application / service owner
+    -> résout endpoints, credentials et rôles
+    -> construit YellowstoneGrpcChannel + YellowstoneSubscribeRequest
+    -> construit HttpTransportPool + hydration role
+    -> construit le Store
+    -> construit RawTransactionIngestRuntimeResources
+    -> construit RawTransactionIngestSettings
+    -> démarre RawTransactionIngestWorker::start_with_runtime_resources
+    -> observe RawTransactionIngestSnapshotSource
+    -> demande stop lorsque nécessaire
+```
+
+Le Worker ne reçoit pas de requête historique métier et ne dépend pas de Config. Une campagne `signature/program_id/plage/limite` appartient à `ksp-job-backfill-lib`.

+//! Source-neutral runtime foundation for continuous KSP RAW transaction ingestion.
+//!
+//! This tranche owns the concrete Worker family identity, validated technical settings
+//! and the caller-runtime-owned lifecycle with private child-task supervision. This tranche also
+//! owns bounded source-neutral admission, common RAW canonicalization/assembly and backend-neutral
+//! Store persistence in normal mode plus concrete latest-value snapshots projected onto Worker API;
+//! the validated Yellowstone/HTTP runtime-resource contract now drives one productive supervised source task.
+//! Transaction/TransactionStatus/Block updates feed bounded HTTP `getTransaction` hydration and the existing central
+//! admission path; BlockMeta/Slot remain continuity-only signals. Hydration is coalesced by network/signature/commitment
+//! under bounded in-flight and pending budgets. A bounded run-local processing frontier projects hydration pending,
+//! oldest pending slot and highest unblocked actually observed slot. The productive source now also projects safe Transport reconnect/replay state and faults
+//! conservatively when Transport proves a replay-retention continuity gap; history remediation remains outside this crate.

+Le ZIP a été contrôlé sans path traversal/entrée absolue, symlink, `.git/`, `target/`, `node_modules/`, `Cargo.lock`, `.env` ou fichier de clé privée détecté.
+
+## Type de livraison
+
+```text
+ksp-general-0.3.10-pre.001.zip
+```
+
+Le type `general` est obligatoire parce que `Cargo.toml` racine est synchronisé vers `0.3.10-pre.1` par `VER-ID-009`. L’archive d’échange ne doit contenir que les fichiers ajoutés/modifiés et le delta, conformément à `VER-ARCHIVE-004`.

+```
+
+`cargo` n’est pas installé dans l’environnement d’assemblage. Aucun gate Cargo local n’est déclaré PASS. Le journal opérateur stable `0.3.9` reste une preuve externe distincte.
+
+## Objectif
+
+Exécuter le gate d’ouverture `0.3.10-pre.001` demandé par le prompt `029` : vérifier intégralement la base `v0.3.9`, auditer l’extraction RAW commune et les capabilities live, réévaluer `TR-B..TR-F`, fixer les frontières Common/Worker/Transport/Config/Store, puis dimensionner les tranches suivantes sans commencer l’implémentation lourde.
+
+## Mission exécutée
+
+`pre.001` reste une tranche de planification, conformément au prompt `029` :
+
+```text
+lecture règles/architecture obligatoires
+inventaire workspace/manifests/features
+extraction RAW commune auditée
+capability matrix Worker implementation-ready
+TR-B..TR-F réévalués
+fraîcheur Solana/Yellowstone/providers revalidée
+runtime/source supervision décidés
+continuité/gap repair décidés
+snapshot concret décidé
+Config/secrets boundary décidée
+threat model et preuves définis
+dependency graph cible fixé
+prereleases redimensionnées
+```
+
+Aucune implémentation lourde des deux nouvelles crates n’est commencée.
+
+## Décisions principales
+
+### Common RAW
+
+```text
+crate : ksp-raw-transaction-lib
+RAW format : ksp.solana.raw_transaction v1 inchangé
+common deps : ksp-core-lib + ksp-store-lib(default-features=false) + serde_json + sha2
+aucun Transport/Config/Job/Worker/runtime/backend
+RawObservationKey reste producer-owned
+Backfill conserve son observation key/job_id/scope_fingerprint/origin
+```
+
+Golden confirmé :
+
+```text
+byte_len = 112
+sha256 = 220792d2b15d262fda242cb220774ee9ddeffebf04dcfadabcf8ef76a9b1a7c3
+```
+
+Toute source full doit prouver une parité byte-for-byte avec RAW v1 avant persistence directe ; sinon elle reste discovery + hydration.
+
+### Worker concret
+
+```text
+crate : ksp-worker-raw-transaction-ingest-lib
+caller-owned Tokio runtime
+Worker-owned source/supervisor tasks
+bounded channels uniquement
+multi-source simultané
+Store idempotence comme vérité de convergence
+observations distinctes conservées
+content conflict terminal
+repair borné au run frontier
+reconnect != replay
+aucun paramètre historique métier au start
+```
+
+### Transport gaps
+
+```text
+TR-B confirmé : get_block_observed
+TR-C confirmé/scindé : common material + adapters Worker + Transport change only if DTO lacks fidelity
+TR-D confirmé : provenance durable full-material + source runtime snapshot
+TR-E confirmé : reuse from_slot/replay info, aucun second Yellowstone client
+TR-F réservé : EARLY seulement si protocole/accès/rôle RAW prouvés
+```
+
+### Config
+
+```text
+aucun edge Worker -> Config
+std.transport V3 actuel réutilisé
+pas de nouveau document métier Worker imposé en 0.3.10
+adaptation Config seulement si un manque Transport concret l’exige
+secrets restent Config-owned et redacted
+```
+
+## Fraîcheur externe
+
+Vérifié le 5 septembre 2026 :
+
+```text
+yellowstone-grpc-proto latest = 12.7.0 (2026-08-29)
+workspace stable = ^12.7 -> aucun bump initial
+Yellowstone block from_slot replay a reçu un fix upstream en juillet 2026 -> smoke block replay obligatoire
+Helius transactionSubscribe courant ; Helius blockSubscribe explicitement non supporté
+Helius LaserStream replay 24 h documenté
+PublicNode Yellowstone Mainnet/Testnet visible ; replay depth non prouvée
+OrbitFlare gRPC Devnet disponible Free/Developer
+QuickNode gRPC Scale+ ; port 443/x-token ; port 10000 sunset 2026-10-01
+Alchemy replay docs contradictoires 6000 vs 432000 slots -> aucune constante KSP
+Jito ShredStream shutdown annoncé pour 2026-09-05 -> SUNSET, non retenu TR-F
+```
+
+## Plan recalibré
+
+```text
+pre.002 common RAW foundation
+pre.003 Backfill migration
+pre.004 observed block + HTTP block material
+pre.005 WS/Helius full parity
+pre.006 Yellowstone parity
+pre.007 Worker runtime foundation
+pre.008 Yellowstone live/replay
+pre.009 WS/HTTP live
+pre.010 multi-source persistence/hardening
+pre.011 gap repair
+pre.012 Config/profiles + smokes accessibles
+pre.013 EARLY si prouvé, sinon consolidation
+pre.014 gate technique/live final

+## Fichiers ajoutés
+
+```text
+docs/plans/031-V0_3_10_RAW_TRANSACTION_INGEST_PLAN.md
+docs/validation/027-V0_3_10_RAW_TRANSACTION_INGEST.md
+deltas/0.3.10/pre.001.md
+```
+
+## Fichiers modifiés
+
+```text
+Cargo.toml
+```
+
+`Cargo.toml` :
+
+```text
+file version 489 -> 490
+workspace.package.version 0.3.9 -> 0.3.10-pre.1
+```
+
+Ce bump est requis par `VER-ID-009` pour toute prerelease non-fix, même lorsque la tranche est documentaire.
+
+## Fichiers supprimés
+
+```text
+aucun
+```
+
+## Validation après modification
+
+Audits statiques réellement exécutés après matérialisation de `pre.001` :
+
+```text
+python3 scripts/audit_rust_workspace_rules.py
+General Rust rule audit: clean
+Rust export completeness audit: 0 candidate(s)
+KSP workspace Rust rule audit: clean
+
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas
+Markdown table audit: clean (339 table(s), 753 file(s))
+```
+
+Le premier passage Markdown post-modification a détecté 32 erreurs d’alignement uniquement dans les nouvelles tables. Elles ont été corrigées selon la règle KSP, puis le gate complet ci-dessus a été relancé jusqu’à PASS.
+
+La comparaison byte-à-byte contre le contenu du ZIP stable, après suppression du cache Python d’audit, donne exactement :
+
+```text
+ajoutés :
+  deltas/0.3.10/pre.001.md
+  docs/plans/031-V0_3_10_RAW_TRANSACTION_INGEST_PLAN.md
+  docs/validation/027-V0_3_10_RAW_TRANSACTION_INGEST.md
+modifié :
+  Cargo.toml
+supprimé :
+  aucun
+```
+
+Les commandes Cargo/Tauri ne sont pas exécutables dans l’environnement d’assemblage courant (`cargo` absent). Elles restent donc explicitement `NON EXÉCUTÉES LOCALEMENT` pour ce delta ; aucune preuve opérateur antérieure n’est transformée en PASS local.
+
+## Validations non exécutées localement
+
+```text
+cargo fmt --all
+cargo check --workspace
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+cargo test --workspace --all-targets --all-features
+cargo tree --duplicates
+builds Tauri
+smokes live opt-in
+```
+
+Motif : toolchain Cargo absent du sandbox d’assemblage et aucune credential/provider live n’est injectée. Les preuves stables fournies par l’opérateur sont conservées comme contexte externe distinct ; elles ne remplacent pas les gates futurs de `0.3.10`.
+
+## Questions ouvertes
+
+Aucune question de boundary ne bloque `pre.002`. Restent volontairement à résoudre par preuve pendant les tranches prévues :
+
+```text
+parité byte-for-byte RAW v1 des sources WS/Helius/Yellowstone full
+profondeur replay réellement observable par provider au moment du smoke
+nécessité éventuelle d’un profil/rôle Transport supplémentaire pour un smoke accessible
+admission d’une source EARLY seulement si protocole, accès et rôle RAW sont effectivement prouvés
+```
+
+Ces points ne doivent pas être anticipés par des constantes, des claims lossless ou une RAW v2.
+
+## Non inclus
+
+```text
+aucune nouvelle crate créée
+aucun Rust modifié
+aucun Transport/Config/Store code modifié
+aucun kbot3 ouvert ou copié
+aucun Worker live
+aucun RAW v2
+aucun CHANGELOG/ROADMAP modifié
+aucun prompt 0.3.11 créé
+aucun Cargo gate déclaré localement

+# Delta `0.3.10-pre.002-fix.001` — correction des canaris d’intégration RAW et du gate Clippy
+
+## Base requise
+
+```text
+livraison : 0.3.10-pre.002
+workspace.package.version = 0.3.10-pre.2
+```
+
+Le delta historique `deltas/0.3.10/pre.002.md` reste inchangé. Le présent fix trace séparément les défauts révélés par la validation opérateur du 2026-09-06.
+
+## Résultat opérateur de la base
+
+La validation communiquée confirme :
+
+```text
+cargo fmt --all : exécuté
+General Rust rule audit: clean
+Rust export completeness audit: 0 candidate(s)
+KSP workspace Rust rule audit: clean
+Markdown table audit: clean (339 table(s), 754 file(s))
+cargo check --workspace : PASS
+cargo test -p ksp-raw-transaction-lib : PASS
+```
+
+Les tests de `ksp-raw-transaction-lib` passent fonctionnellement :
+
+```text
+9 tests unitaires : PASS
+8 tests d’intégration : PASS
+0 échec
+```
+
+Les graphes communiqués confirment la frontière prévue :
+
+```text
+ksp-core-lib
+ksp-store-api
+serde_json
+sha2
+```
+
+Aucun runtime, Transport, Config, Job, Worker ou backend Store n’apparaît dans le graphe normal de la common crate.
+
+## Motif du fix
+
+Le gate strict :
+
+```bash
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+```
+
+échoue exclusivement sur les nouveaux tests d’intégration de `ksp-raw-transaction-lib`.
+
+### Rustdoc de crate manquante
+
+Quatre fichiers `tests/*.rs` n’avaient pas de documentation de crate :
+
+```text
+crates/ksp-raw-transaction-lib/tests/dependency_boundary.rs
+crates/ksp-raw-transaction-lib/tests/public_api.rs
+crates/ksp-raw-transaction-lib/tests/release_completeness.rs
+crates/ksp-raw-transaction-lib/tests/security_hardening.rs
+```
+
+Avec `missing_docs` promu en erreur par `-D warnings`, chaque binaire de test d’intégration doit documenter sa crate.
+
+Correction : ajout d’une rustdoc `//! ...` conforme aux autres tests d’intégration KSP. Aucun `#[allow(missing_docs)]` n’est ajouté.
+
+### `clippy::collapsible_if`
+
+Le canari d’inventaire des modules production utilisait deux conditions imbriquées pour filtrer les fichiers `.rs` puis extraire leur nom.
+
+Correction : filtrage anticipé avec `continue`, puis `let ... else`, sans `#[allow(clippy::collapsible_if)]` et sans changement de l’inventaire attendu.
+
+## Version Cargo
+
+Ce fix modifie du Rust de test. Le signal technique Cargo est donc synchronisé :
+
+```text
+0.3.10-pre.2 -> 0.3.10-pre.2.fix.1
+```
+
+Le header du `Cargo.toml` racine passe de `491` à `492`.

+# Delta `0.3.10-pre.002` — fondation RAW Transaction commune
+
+## Base requise
+
+```text
+0.3.10-pre.001
+workspace.package.version = 0.3.10-pre.1
+```
+
+Le gate opérateur communiqué pour `pre.001` passe `cargo fmt --all`, les audits Rust/Markdown, `cargo check --workspace` et Clippy workspace `--all-targets --all-features -- -D warnings`. Le message ne fournit pas de `cargo test` supplémentaire ; aucun test non communiqué n’est déclaré exécuté.
+
+## Objectif
+
+Créer uniquement `ksp-raw-transaction-lib` comme lower-layer commune de canonicalisation RAW Transaction v1 : matériau source-neutral, parser de signature, canonical JSON, SHA-256 et assemblage transaction/observation. Aucun Worker et aucune migration du Backfill dans cette tranche.
+
+## Version
+
+Cette tranche est une prerelease non-fix :
+
+```text
+workspace.package.version = 0.3.10-pre.2
+```
+
+Le `Cargo.toml` racine passe du header `490` au header `491` et ajoute `crates/ksp-raw-transaction-lib` aux membres du workspace.
+
+## Correction normative du plan `pre.001`
+
+Le sizing `pre.001` avait retenu `ksp-store-lib(default-features=false)` pour la common crate. La relecture au moment de matérialiser la frontière révèle une règle plus spécifique :
+
+```text
+DEP-PIPE-006
+Le pipeline raw ingestion peut dépendre des modèles homogènes de
+ksp-onchain-transport-lib et de ksp-store-api, mais pas de ksp-store-lib.
+```
+
+La dépendance est donc corrigée vers `ksp-store-api`. Cette correction ne change aucun invariant RAW ; elle retire au contraire la façade/runtime Store de la lower-layer réutilisable.
+
+## Dépendances exactes
+
+```text
+ksp-raw-transaction-lib
+    -> ksp-core-lib
+    -> ksp-store-api

+```
+
+Tous les modules restent privés et les éléments consommables sont réexportés au crate-root.
+
+## Contrat matérialisé
+
+### Signature
+
+Le parser reçoit un texte Base58 borné de `64..=88` octets et n’accepte que les représentations décodant exactement vers `64` octets. Aucun Solana SDK ou codec externe n’est ajouté.
+
+Les erreurs ne recopient jamais la signature hostile ; seules les longueurs numériques sûres peuvent apparaître en contexte.
+
+### Matériau source-neutral
+
+`RawTransactionMaterial::binary_base64(...)` reçoit :
+
+```text
+network
+signature canonique 64 bytes
+slot u64
+block_time Option<i64>
+transaction data binaire Base64 déjà obtenu de la source
+meta omitted/null/value
+version omitted/null/value (legacy ou u8)
+transactionIndex omitted/null/value u32
+```
+
+Aucun type Transport/provider n’entre dans la common crate. La représentation interne peut être étendue ultérieurement pour Yellowstone uniquement lorsqu’une parité RAW v1 sera démontrée.
+
+### Canonicalisation RAW v1
+
+La sortie conserve exactement :
+
+```text
+ordre top-level : transaction -> meta -> version -> transactionIndex
+transaction = [data, "base64"]
+tri récursif des clés d’objets JSON
+ordre des arrays conservé
+omitted != null != value
+block_time hors payload, converti en RawTimestamp
+SHA-256 sur les bytes canoniques exacts
+format id/version gelés
+```
+
+Golden verrouillé :
+
+```text
+bytes = {"transaction":["AQID","base64"],"meta":{"a":{"x":null,"y":true},"z":1},"version":"legacy","transactionIndex":7}
+byte_len = 112
+sha256 = 220792d2b15d262fda242cb220774ee9ddeffebf04dcfadabcf8ef76a9b1a7c3
+```
+
+### Observation producer-owned
+
+`assemble_raw_transaction_acquisition(...)` reçoit la `RawObservationKey` déjà choisie par le producteur et construit l’observation sur la référence exacte de la transaction. Aucun domaine de clé Backfill ou Worker n’est introduit dans common.
+
+## Tests ajoutés
+
+Tests unitaires :
+
+```text
+signature exacte 64 bytes
+signature bornes / caractère Base58 invalide / overflow / longueur décodée non canonique
+golden bytes + hash RAW v1
+omitted/null/value

+block_time négatif / overflow / maximum

+Debug material/wire redacted

+# Delta `0.3.10-pre.003` — migration du Backfill vers la common RAW Transaction
+
+## Base requise
+
+```text
+0.3.10-pre.002-fix.001
+workspace.package.version = 0.3.10-pre.2.fix.1
+```
+
+Le gate opérateur communiqué le 2026-09-06 ferme intégralement la base : audits statiques propres, `cargo check --workspace` PASS, Clippy workspace `--all-targets --all-features -- -D warnings` PASS, `cargo test -p ksp-raw-transaction-lib` PASS avec 9 tests unitaires et 8 tests d’intégration, arbres normal/features conformes.
+
+## Objectif
+
+Migrer uniquement `ksp-job-backfill-lib` vers `ksp-raw-transaction-lib` sans modifier le comportement de campagne : common devient propriétaire du parser Base58, de RAW v1, du hash payload et de l’assemblage transaction/observation ; Backfill conserve Transport, provenance, observation key, Job scope et Store persistence.
+
+Aucun Worker, aucune nouvelle source Transport et aucune extension du format RAW ne sont introduits.
+
+## Version
+
+```text
+workspace.package.version = 0.3.10-pre.3
+```
+
+Le header du `Cargo.toml` racine passe de `492` à `493`. Le nombre de membres workspace reste `20`.
+
+## Migration de dépendance
+
+`ksp-job-backfill-lib` ajoute :
+
+```text
+ksp-raw-transaction-lib = { path = "../ksp-raw-transaction-lib" }
+```
+
+Le reste de son graphe runtime est conservé. `serde_json` reste nécessaire au type Transport `SolanaWireField<serde_json::Value>`. `sha2` reste nécessaire aux fingerprints et à la `RawObservationKey` Backfill ; il n’est plus utilisé pour le hash du payload RAW.
+
+## Chemin RAW après migration
+
+```text
+BackfillSignature
+    -> parse_raw_transaction_signature
+    -> RawTransactionSignature
+
+getTransaction observed
+    -> adapter SolanaEncodedTransaction/SolanaWireField
+    -> RawTransactionMaterial::binary_base64
+    -> canonicalize_raw_transaction
+    -> RawTransaction
+
+Backfill provenance + Backfill RawObservationKey
+    -> assemble_raw_transaction_acquisition
+    -> BackfillRawAcquisition
+    -> Store persistence existante
+```
+
+Les erreurs du parser/canonicalizer common sont remappées au boundary Backfill vers :
+
+```text
+ERROR_CODE_BACKFILL_RAW_CONVERSION_INVALID
+```
+
+Le Job ne change donc pas de domaine d’erreur externe par effet de la migration.
+
+## Code privé supprimé du Backfill
+
+La migration retire de `conversion.rs` les implémentations locales de :
+
+```text
+base58_digit(...)
+algorithme de décodage Base58 64-byte
+convert_block_time(...)
+canonical_payload_bytes(...)
+append_wire_value(...)
+append_canonical_json(...)
+append_json_string(...)
+RawPayload::try_new + SHA-256 du payload
+construction directe RawTransactionObservation
+```
+
+`CanonicalTransactionFields` reste un adapter Transport privé ; il ne définit aucun format RAW.
+
+## Propriété Backfill conservée
+
+Le Backfill continue de posséder :
+
+```text
+getTransaction observed / rôle HTTP
+provider gagnant
+endpoint gagnant
+commitment
+job_id
+scope_fingerprint
+RawAcquisitionOrigin::Backfill
+capture_session
+observation contract version = 1
+algorithme RawObservationKey Backfill
+persistence Store
+sémantique Missing
+```
+
+La common crate ne reçoit donc aucun vocabulaire de campagne.
+
+## Parité déterministe
+
+Le golden historique reste inchangé :
+
+```text
+format_id = ksp.solana.raw_transaction
+format_version = 1
+bytes = {"transaction":["AQID","base64"],"meta":{"a":{"x":null,"y":true},"z":1},"version":"legacy","transactionIndex":7}
+byte_len = 112
+sha256 = 220792d2b15d262fda242cb220774ee9ddeffebf04dcfadabcf8ef76a9b1a7c3
+```
+
+La provenance historique reste :
+
+```text
+provider = publicnode
+protocol = solana.http.json_rpc
+method = getTransaction
+endpoint = devnet-primary
+commitment = finalized
+capture_session = backfill:pre006
+origin = Backfill
+```
+
+Le canari d’observation key est désormais exact :
+
+```text
+provider = provider
+endpoint = endpoint-a
+key = b8550f0f2165f370de918bd4fb0ec782391afdddb88c57f010743e000b136702
+```
+
+## Canaris mis à jour
+
+```text
+BackfillSignature délègue au parser common
+bornes Backfill == bornes common
+format id/version Backfill == common
+wire omitted/null reste distinct via common
+non-Base64 reste rejeté avec error code Backfill
+block_time invalide reste terminal avec error code Backfill
+golden bytes/hash/provenance inchangés
+observation key exacte inchangée
+manifest Backfill exige l’edge common
+conversion.rs exige parser + canonicalizer + assembler common
+conversion.rs interdit canonical JSON/Base58/RawPayload privés
+lower-layer common interdit toute dépendance retour vers Job

+
+## Base requise
+
+```text
+livraison : 0.3.10-pre.004
+workspace.package.version = 0.3.10-pre.4
+```
+
+Le delta historique `deltas/0.3.10/pre.004.md` reste inchangé. Le présent fix trace séparément le défaut révélé par la validation opérateur du 2026-09-06.
+
+## Résultat opérateur de la base
+
+La validation communiquée confirme :
+
+```text
+cargo fmt --all : exécuté
+General Rust rule audit: clean
+Rust export completeness audit: 0 candidate(s)
+KSP workspace Rust rule audit: clean
+Markdown table audit: clean (339 table(s), 757 file(s))

+cargo test -p ksp-raw-transaction-lib : PASS
+cargo test -p ksp-onchain-transport-lib : PASS
+cargo test -p ksp-job-backfill-lib --test http_block_material : PASS
+```
+
+Les tests fonctionnels communiqués confirment notamment :
+
+```text
+ksp-raw-transaction-lib : 12 unit + 9 intégration, 0 échec
+ksp-onchain-transport-lib : 387 unit + 51 public API + 43 release completeness + 4 doctests, 0 échec
+http_block_material : 1 test, PASS
+smokes live Transport : ignorés comme prévu
+```
+
+Les arbres normaux communiqués conservent les frontières prévues : la common RAW dépend de `base64`, `ksp-core-lib`, `ksp-store-api`, `serde_json`, `sha2`, et `ksp-onchain-transport-lib` ne dépend pas de `ksp-raw-transaction-lib`.
+
+## Motif du fix
+
+Le gate strict :
+
+```bash
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+```
+
+échoue exclusivement sur sept `clippy::expect_used` dans les deux helpers privés du nouveau test d’intégration :
+
+```text
+pool_for_url(...)
+serve_once(...)
+```
+
+Les usages concernés sont :
+
+```text
+parsing HttpEndpointUrl
+construction HttpTransportPool
+bind du listener local
+lecture de local_addr
+accept de la connexion fixture
+read de la requête fixture
+write de la réponse fixture
+```
+
+La configuration commune autorise `expect` dans les fonctions de test, mais ces helpers ne portent pas eux-mêmes l’attribut `#[test]`/`#[tokio::test]` et sont donc correctement rejetés par Clippy.
+
+## Correction
+
+Aucun lint n’est désactivé.
+
+`pool_for_url(...)` retourne désormais explicitement :
+
+```text
+ksp_core_lib::Result<HttpTransportPool>
+```
+
+et propage les deux erreurs possibles par `match` explicite.
+
+`serve_once(...)` retourne désormais :
+
+```text
+std::io::Result<(String, JoinHandle<std::io::Result<()>>)> 
+```
+
+Le bind, `local_addr`, `accept`, `read` et `write_all` retournent leurs erreurs par contrôle de flux explicite. Les assertions/`expect()` de fixture restent uniquement dans le corps `#[tokio::test]`, conformément à `allow-expect-in-tests = true`.
+
+## Version Cargo
+
+Ce fix modifie du Rust de test. Le signal technique Cargo est donc synchronisé :
+
+```text
+0.3.10-pre.4 -> 0.3.10-pre.4.fix.1
+```
+
+Le header du `Cargo.toml` racine passe de `494` à `495`.
+

+
+```text
+0.3.10-pre.003
+workspace.package.version = 0.3.10-pre.3
+```
+
+Le gate opérateur communiqué le 2026-09-06 ferme intégralement `pre.003` : audits statiques propres, `cargo check --workspace` PASS, Clippy workspace `--all-targets --all-features -- -D warnings` PASS, tests de `ksp-raw-transaction-lib` PASS, tests de `ksp-job-backfill-lib` PASS avec 51 tests unitaires et 20 tests d’intégration, arbres normal/features conformes.
+
+## Objectif
+
+Fermer `TR-B` et la preuve HTTP block de `TR-C` sans ouvrir le Worker :
+
+```text
+getBlock pool HTTP
+    -> valeur observée + provider/endpoint winner
+    -> SolanaConfirmedBlock
+    -> N SolanaBlockTransaction full Base64
+    -> matériau RAW source-neutral
+```
+
+La tranche ne crée aucun adapter productif Transport -> common. Conformément à `TR-C2`, cet adapter reste producer-owned et sera matérialisé dans le futur `ksp-worker-raw-transaction-ingest-lib`.
+
+## Version
+
+```text
+workspace.package.version = 0.3.10-pre.4
+```
+
+Le header du `Cargo.toml` racine passe de `493` à `494`. Le nombre de membres workspace reste `20`.
+
+## `get_block_observed`
+
+`ksp-onchain-transport-lib` ajoute :
+
+```text
+HttpTransportPool::get_block_observed(...)
+```
+
+Le wrapper :
+
+```text
+réutilise exactement la validation/config moderne de get_block
+utilise le routing/admission/timeout/retry standard du pool
+retourne HttpObservedValue<Option<SolanaConfirmedBlock>>
+conserve endpoint_name + provider du winner réel après retry/reroute
+préserve result = null comme None
+n’expose ni URL, ni headers, ni raw HTTP body
+réutilise le décodage typé SolanaConfirmedBlock
+```
+
+`get_block(...)` et `get_block_observed(...)` partagent désormais le même helper privé de paramètres et la même validation du commitment `processed`.
+
+## Provenance winner déterministe
+
+Le canari Transport configure deux endpoints :
+
+```text
+endpoint 1 -> HTTP 429
+endpoint 2 -> getBlock success
+```
+
+La valeur observée doit reporter exclusivement :
+
+```text
+endpoint_name = winner-endpoint
+provider = winner-provider
+```
+
+Le Debug conserve uniquement la projection sûre et ne rend pas le transaction wire Base64.
+
+## Matériau Base64 source-neutral
+
+`ksp-raw-transaction-lib` ajoute `base64` à son graphe common et expose :
+
+```text
+extract_raw_transaction_signature_from_binary_base64(...)
+RawTransactionMaterial::binary_base64_with_embedded_signature(...)
+```
+
+L’extracteur lit directement le wire transaction Solana Base64 sans dépendance à une crate transaction runtime :
+
+```text
+borne la représentation textuelle avant décodage
+exige Base64 STANDARD canonique
+lit un short_vec de signature count borné et canonique
+refuse count = 0
+refuse short_vec tronqué/non canonique
+refuse tableau de signatures tronqué
+exige au moins un byte de message après les signatures déclarées
+retourne uniquement la première signature exacte de 64 octets
+ne copie jamais le transaction wire dans erreur/Debug
+```
+
+Le constructeur common réutilise cette signature puis conserve les dimensions RAW v1 existantes :
+
+```text
+network
+slot
+block_time
+transaction Base64
+meta omitted/null/value
+version omitted/null/legacy/number
+transaction_index
+```
+
+Le format canonique reste strictement `ksp.solana.raw_transaction` v1.
+
+## Preuve cross-layer sans nouveau couplage de production
+
+Le nouveau canari test-only :
+
+```text
+crates/ksp-job-backfill-lib/tests/http_block_material.rs
+```
+
+utilise une crate qui dépend déjà de Transport et de common pour prouver la composition future sans créer d’edge architectural supplémentaire :
+
+```text
+get_block_observed
+    -> SolanaConfirmedBlock
+    -> 2 SolanaBlockTransaction distinctes
+    -> full Base64 + meta + version + transactionIndex 0/1
+    -> RawTransactionMaterial::binary_base64_with_embedded_signature
+    -> canonicalize_raw_transaction
+```
+
+Les deux transaction wires minimales font `66` octets chacune et utilisent des signatures distinctes :
+
+```text
+transaction 0 -> signature [0; 64]
+transaction 1 -> signature [1; 64]
+```
+
+Le canari vérifie que ces signatures et les index 0/1 restent associés à la bonne transaction, avec le slot et le block time communs du bloc.
+
+Cette preuve reste strictement test-only. Aucun symbole `ksp_raw_transaction_lib` n’est ajouté aux sources de production de `ksp-onchain-transport-lib`.
+
+## Dépendances common
+
+Le graphe runtime direct de `ksp-raw-transaction-lib` devient exactement :
+
+```text
+base64
+ksp-core-lib
+ksp-store-api
+serde_json
+sha2
+```
+
+Restent interdits :
+
+```text
+ksp-store-lib
+ksp-onchain-transport-lib
+ksp-config-lib
+ksp-job-api
+ksp-job-backfill-lib
+ksp-worker-api
+tokio
+futures
+```
+
+La règle `DEP-PIPE-006` reste donc respectée.
+
+## Documentation durable
+
+`crates/ksp-onchain-transport-lib/USAGE.md` documente la différence entre :
+
+```text
+get_block(...)
+get_block_observed(...)
+```
+
+sans transformer le guide en journal de prerelease.
+
+`docs/architecture/011-RAW_TRANSACTION_ACQUISITION.md` ferme `TR-B`, conserve `TR-C2` producer-owned et corrige le graphe common vers `ksp-store-api`.
+
+Le plan `031` et la validation `027` enregistrent également la fermeture opérateur de `pre.003` et le périmètre exact de `pre.004`.

+# Delta `0.3.10-pre.005-fix.001` — correction de typage du canari WS RAW parity
+
+## Base requise
+
+```text
+0.3.10-pre.005
+```
+
+## Motif du fix
+
+Le premier rejeu opérateur de `pre.005` valide les audits statiques, `cargo check --workspace`, la common RAW, la suite Transport complète et les arbres Cargo, mais Clippy strict et la suite Backfill s’arrêtent sur une unique erreur de compilation `E0308` dans `tests/ws_raw_parity.rs`.
+
+Le canari comparait :
+
+```text
+RawTransaction::block_time().unix_millis() -> u64
+FIXTURE_BLOCK_TIME * 1_000                 -> i64
+```
+
+L’assertion produisait donc `Option<u64> != Option<i64>` au niveau du type.
+
+## Correction
+
+La constante de fixture devient directement :
+
+```text
+FIXTURE_BLOCK_TIME_MILLIS: u64 = 1_787_072_400_000
+```
+
+L’assertion compare désormais `Option<u64>` à `Option<u64>` sans cast, conversion runtime, `unwrap`, `expect` ou modification du comportement testé.
+
+## Invariants inchangés
+
+```text
+blockSubscribe standard confirmed/full/base64 legacy-v0 -> golden RAW-direct positif
+Helius transactionSubscribe full/base64 -> signal + hydration HTTP
+RAW v1 bytes/hash contracts
+TR-C2 Worker-owned

+aucun code de production modifié
+aucune dépendance ni feature modifiée
+```
+

+
+## Base requise
+
+```text
+0.3.10-pre.005-fix.001
+```
+
+## Motif du fix
+
+Le second rejeu opérateur confirme `cargo check --workspace`, la common RAW et la suite Transport complète, mais révèle deux défauts test-only :
+
+```text
+25 clippy::question_mark_used dans crates/ksp-job-backfill-lib/tests/ws_raw_parity.rs
+1 canari hardening encore calibré sur dev-dependencies = {tokio}
+```
+
+Le manifest `pre.005` contient légitimement `tokio-tungstenite` en dev-only pour les serveurs WebSocket déterministes ; `tests/dependency_boundary.rs` verrouille déjà qu’il ne migre pas vers les dépendances de production.
+
+## Corrections
+
+`ws_raw_parity.rs` remplace tous les `?` par du contrôle de flux explicite :
+
+```text
+Option -> match + retour None
+Result -> match + retour Err/None
+appel async Result -> if let Err(error) + retour Err(error)
+```
+
+Aucun `#[allow(...)]`, aucun changement de golden et aucune modification du scénario positif `blockSubscribe` ou négatif Helius ne sont introduits.
+
+`hardening.rs` attend désormais exactement :
+
+```text
+dev-dependencies = {tokio, tokio-tungstenite}
+```
+
+L’inventaire des dépendances normales reste inchangé.
+
+## Invariants inchangés

+# Delta `0.3.10-pre.005` — qualification RAW WS standard et Helius
+
+## Base requise
+
+```text
+livraison : 0.3.10-pre.004-fix.001
+workspace.package.version = 0.3.10-pre.4.fix.1
+```
+
+Le rejeu opérateur communiqué le 2026-09-06 ferme intégralement le fix : audits statiques propres, `cargo check --workspace` PASS, Clippy strict PASS, tests common PASS, 387 tests Transport plus suites publiques/release/doctests PASS, et suite complète Backfill PASS. Les arbres Cargo n'ont pas été rejoués sur le fix car aucune dépendance ni feature n'y avait changé.
+
+## Objectif
+
+Qualifier les deux surfaces WebSocket déjà présentes sans ouvrir le Worker :
+
+```text
+Solana standard blockSubscribe full/base64
+    -> prouver ou refuser la production RAW directe
+
+Helius transactionSubscribe full/base64
+    -> prouver ou refuser la production RAW directe
+```
+
+Aucun adapter productif n'est placé dans Transport ou Backfill. `TR-C2` reste Worker-owned.
+
+## Version
+
+```text
+workspace.package.version = 0.3.10-pre.5
+```
+
+Le header du `Cargo.toml` racine passe de `495` à `496`. Le workspace reste à `20` membres.
+
+## Qualification positive — `blockSubscribe`
+
+Le canari cross-layer `crates/ksp-job-backfill-lib/tests/ws_raw_parity.rs` monte un serveur HTTP local et un serveur WebSocket standard local sur une fixture commune.
+
+Configuration qualifiée :
+
+```text
+commitment = confirmed
+encoding = base64
+transactionDetails = full
+maxSupportedTransactionVersion = 0
+showRewards = false
+```
+
+Le test compare :
+
+```text
+HTTP getBlock observed
+    vs
+WS blockSubscribe
+```
+
+puis exige :
+
+```text
+même SolanaConfirmedBlock
+même RawTransactionReference
+même slot
+même block_time
+mêmes bytes RAW v1
+même content_hash
+```
+
+La qualification directe est volontairement bornée au sous-ensemble legacy/v0 prouvé. Transaction V1 reste au gate `pre.006`.
+
+## Qualification négative — Helius `transactionSubscribe`
+
+Le même canari ouvre une session Helius locale et une hydration HTTP de référence pour la même transaction.
+
+L'enveloppe full/base64 qualifiée conserve :
+
+```text
+transaction wire
+meta
+signature
+slot
+transactionIndex
+```
+
+mais ne porte pas, dans le contrat typé actuel :
+
+```text
+blockTime
+version
+```
+
+Le test construit donc la meilleure projection RAW possible sans inventer ces champs et prouve :
+
+```text
+même identité que HTTP
+même slot que HTTP
+block_time différent
+bytes RAW v1 différents
+content_hash différent
+```
+
+Décision normative :
+
+```text
+Helius transactionSubscribe full/base64
+    -> signal live riche
+    -> HTTP hydration obligatoire
+    -> persistence RAW depuis le matériau HTTP complet
+```
+
+Aucun RAW v2 automatique et aucune normalisation ad hoc ne sont introduits.
+
+## Dependency firewall
+
+Pour les serveurs WebSocket locaux du canari, le manifest Backfill ajoute uniquement :
+
+```text
+[dev-dependencies]
+tokio-tungstenite = { workspace = true, features = ["handshake"] }
+```
+
+`tests/dependency_boundary.rs` vérifie explicitement que `tokio-tungstenite` n'apparaît pas dans `[dependencies]` et reste dans `[dev-dependencies]`.
+
+Il n'existe toujours aucun edge productif :
+
+```text
+ksp-onchain-transport-lib -> ksp-raw-transaction-lib
+ksp-raw-transaction-lib -> ksp-onchain-transport-lib
+```
+
+## Documentation
+
+`docs/architecture/011-RAW_TRANSACTION_ACQUISITION.md` distingue désormais :
+
+```text
+blockSubscribe full/base64 legacy-v0 -> direct après parité prouvée
+Helius transactionSubscribe full/base64 -> signal + hydration HTTP
+```
+
+Le plan `031` et la validation `027` enregistrent la même qualification, la fermeture opérateur de `pre.004-fix.001` et le maintien de Transaction V1 dans `pre.006`.
+
+## Fraîcheur externe revalidée
+
+Les surfaces changeantes ont été revalidées le 2026-09-06 :
+
+```text
+Solana blockSubscribe : méthode unstable, confirmed/finalized, base64, full, maxSupportedTransactionVersion disponible
+Helius transactionSubscribe : full transaction streaming disponible ; enveloppe KSP qualifiée sans blockTime/version
+```
+
+Sources documentaires :
+
+```text
+https://solana.com/docs/rpc/websocket/blocksubscribe
+https://solana.com/docs/rpc/json-structures
+https://www.helius.dev/docs/rpc/websocket/transaction-subscribe
+https://www.helius.dev/blog/introducing-next-generation-enhanced-websockets
+```
+
+Ces faits d'accès/protocole restent documentaires et ne deviennent pas des constantes provider dans le Worker.

+

+# Delta `0.3.10-pre.006-fix.001` — corrections Rust du gate `pre.006` + recalibrage du sizing
+
+## Base requise
+
+```text
+0.3.10-pre.006
+```
+
+L'archive opérateur `khadhroony-solana-project- v0.3.10-pre.006.zip` est la base autoritaire de ce correctif.
+
+## Objectif
+
+Corriger strictement les défauts Rust révélés par le premier gate opérateur de `pre.006` sans modifier le contrat RAW V1, les goldens, la décision Yellowstone ni les dépendances de production, puis corriger le plan devenu surdimensionné avant toute implémentation lourde du Worker.
+
+Le gate opérateur a révélé trois familles de défauts dans la responsabilité `pre.006` :
+
+```text
+clippy::collapsible_if dans la validation V1 du heap size
+assert_eq! sur Result<&str, &Error> exigeant à tort PartialEq sur Error
+canari Yellowstone utilisant Error::new avec un &str et formatant ErrorCode via Display inexistant
+```
+
+## Version
+
+Le correctif modifie du Rust et synchronise donc la version technique Cargo conformément à `VER-ID-007` et `VER-ID-010` :
+
+```text
+workspace.package.version = 0.3.10-pre.6.fix.1
+```
+
+## Corrections Rust
+
+`ksp-raw-transaction-lib/src/wire.rs` applique la forme Clippy proposée pour la garde `heap_size` V1 sans modifier les bornes ni le résultat fonctionnel.
+
+`unit_tests/wire.rs` conserve exactement les quatre golden Base64 mais compare les succès par pattern matching, sans imposer `PartialEq` au type d'erreur KSP.
+
+`yellowstone_raw_parity.rs` construit désormais l'erreur de projection test-only avec un `ErrorCode` structuré et formate les codes d'erreur explicitement via `domain()` + `code()`. Aucun code d'erreur public de production n'est ajouté.
+
+## Recalibrage du sizing
+
+Le plan initial associait dans `0.3.10` deux moitiés devenues nettement séparables :
+
+```text
+common RAW + migration/parités            = déjà matérialisées en pre.002 à pre.006
+runtime Worker + sources + repair          = pas encore commencé
+```
+
+Les anciennes tranches `pre.007` à `pre.011` cumulaient plusieurs responsabilités chacune et ne respectaient plus le budget normatif d'environ 15 à 20 minutes. La clôture de toute la mission initiale dans une seule session devenait également incertaine.
+
+Le redécoupage durable retenu est donc :
+
+```text
+0.3.10 = common RAW + observed block + qualification HTTP/WS/Helius/Yellowstone
+0.3.11 = Worker foundation/runtime + persistence déterministe
+0.3.12 = Yellowstone + hydration HTTP + continuity
+0.3.13 = WS/Helius/HTTP live + convergence multi-source
+0.3.14 = gap repair/hardening + smokes provider accessibles
+0.3.15 = Desk d'ingestion
+0.3.16 = Backfill multi-source/multi-stratégie
+```
+
+La queue de fermeture de `0.3.10` devient :
+
+```text
+pre.007 = gate technique final, budget 15-20 min
+pre.008 = réconciliation documentaire, budget 10-15 min
+pre.009 = préparation de publication, budget 5-10 min
+rel.001 = publication stable mécanique
+```
+
+Chaque nouvelle release Worker recommencera par sa propre `pre.001` de sizing et devra scinder toute prerelease estimée au-delà du budget.
+
+## Vérification de l'archive
+
+Exécuté sur l'archive autoritaire avant modification :
+
+```text
+unzip -t                                  : PASS
+racine ZIP unique                         : PASS

+règles obligatoires présentes             : PASS
+```
+
+## Validations exécutées
+
+Après les corrections Rust et le recalibrage documentaire :
+
+```bash
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas/0.3.10

+
+Résultats :

+KSP workspace Rust rule audit              : clean
+Markdown table audit                       : clean
+```
+
+Les contrôles structurels ont également vérifié que le delta ne contient aucun chemin d'archive dangereux et que les références durables principales du nouveau découpage sont cohérentes.
+
+## Validations non exécutées dans l'environnement d'assemblage
+
+L'environnement d'assemblage ne fournit ni `cargo`, ni `rustc`, ni `rustfmt`. Les commandes suivantes ne sont donc **pas** déclarées PASS ici :
+
+```bash

+- Les goldens Legacy/V0/V1 et le contrat RAW V1 de `pre.006` ne changent pas.
+- Le canari Yellowstone reste test-only et n'ajoute aucun nouvel edge productif.
+- `0.3.10` est réduit à la common RAW et aux qualifications cross-source déjà matérialisées avant ouverture du runtime Worker.
+- Le Worker concret est réparti sur `0.3.11` à `0.3.14` afin de respecter une release concrète par session et des prereleases bornées.
+- La Desk et le Backfill multi-source sont décalés respectivement à `0.3.15` et `0.3.16`.
+- Les anciens prompts/plans de releases déjà ouvertes restent des traces historiques et ne sont pas réécrits rétroactivement uniquement pour refléter ce recalibrage.
+
+## Questions ouvertes
+
+Aucune question fonctionnelle nouvelle pour ce fix. Le prochain gate est le rejeu Rust opérateur du correctif, puis `pre.007` si ce rejeu est vert.

+Le gate opérateur du 7 septembre 2026 confirme que les erreurs Rust corrigées par `fix.001` ont disparu. Le seul blocage restant sous Clippy strict est le lint crate-level `missing_docs` de `crates/ksp-job-backfill-lib/tests/yellowstone_raw_parity.rs`.
+
+## 2. Version technique
+
+Le correctif modifie un test Rust compilé. Conformément à `VER-ID-007` / `VER-ID-010` :
+
+```text
+workspace.package.version = 0.3.10-pre.6.fix.2
+commit attendu            = v0.3.10-pre.006-fix.002
+aucun tag prerelease
+```
+
+Aucune version npm/Tauri n'est modifiée : aucune application Desk n'est touchée.
+
+## 3. Correction Rust
+
+`tests/yellowstone_raw_parity.rs` reçoit la rustdoc crate-level manquante :
+
+```text
+//! Deterministic local Yellowstone gRPC parity canary for source-neutral RAW transaction v1 projection.
+```
+
+Aucun `#[allow(missing_docs)]` n'est ajouté. Le serveur fixture, la projection Yellowstone, les goldens, les assertions et les dépendances restent inchangés.
+
+## 4. Inventaire des composants
+
+`docs/architecture/004-COMPONENT_INVENTORY.md` :
+
+```text
++ ksp-raw-transaction-lib comme common RAW Transaction implémentée en 0.3.10
+CORE processor -> STRUCTURAL job
+CORE worker    -> STRUCTURAL worker
+```
+
+Le Job STRUCTURAL représente le traitement borné/rejouable RAW -> CORE ; le Worker STRUCTURAL représente le service continu backlog RAW -> CORE. Les références durables correspondantes dans `009-ACQUISITION_WORKERS_AND_JOBS.md`, `010-APPS_SERVICES_SCENARIOS_AND_CONTROL.md` et la séquence fonctionnelle active sont synchronisées. Les noms/packagings concrets restent à fixer lors de l'ouverture de la couche CORE.
+
+## 5. Graphe de dépendances
+
+`docs/architecture/005-DEPENDENCY_GRAPH.md` matérialise la lower layer réelle :
+
+```text
+ksp-raw-transaction-lib
+    -> ksp-store-api
+    -> ksp-core-lib
+    -> base64 / serde_json / sha2
+
+-X-> Transport
+-X-> ksp-store-lib
+-X-> Job / Worker
+-X-> Config / runtime async / backend Store
+```
+
+Le graphe Backfill ajoute son edge réel vers `ksp-raw-transaction-lib`, et le graphe du futur Worker réserve la même common crate avant la persistence par `ksp-store-lib`.
+
+## 6. Note de génération des prompts `0.3.12` à `0.3.15`
+
+Le plan `031` n'introduit pas quatre prompts prématurés. Il fixe un handoff séquentiel :
+
+```text
+0.3.11 ferme -> génère le prompt 0.3.12
+0.3.12 ferme -> génère le prompt 0.3.13
+0.3.13 ferme -> génère le prompt 0.3.14
+0.3.14 ferme -> génère le prompt 0.3.15
+```
+
+Chaque prompt doit partir de la base stable réellement obtenue, refaire son audit/sizing `pre.001`, rester sous le budget 15–20 min par tranche et rescinder sa release si la clôture dans une session devient incertaine. La note transfère les missions Yellowstone, WS/Helius/HTTP, gap repair/hardening puis Desk sans les figer comme vérité future.
+
+Le plan corrige aussi l'ancienne référence résiduelle de la Desk `0.3.11` vers sa cible recalibrée `0.3.15`.
+
+## 7. Validation opérateur requise
+
+```bash

+cargo tree -p ksp-job-backfill-lib -e features
+```
+
+Aucune commande ne doit être déclarée PASS avant exécution réelle. Si ce gate est vert, `pre.006-fix.002` ferme le défaut technique restant de `pre.006` et `pre.007` peut rester le gate technique final recalibré de `0.3.10`.

+# Delta `0.3.10-pre.006` — Transaction V1 + parité Yellowstone transaction/block
+
+## Base requise
+
+```text
+livraison : 0.3.10-pre.005-fix.002
+workspace.package.version = 0.3.10-pre.5.fix.2
+```
+
+Le gate opérateur communiqué le 2026-09-06 ferme cette baseline : audits statiques propres, `cargo check --workspace` PASS, Clippy strict PASS, common RAW PASS, 387 tests Transport avec suites publiques/release/doctests PASS, et suite Backfill complète PASS, y compris hardening et les deux canaris WS/Helius.
+
+## Objectif
+
+Fermer avant le Worker concret :
+
+```text
+Transaction V1 / SIMD-0385 dans la common source-neutral
+Yellowstone Transaction -> transaction wire exact
+Yellowstone Block       -> même transaction wire + block_time
+qualification RAW-direct vs hydration
+```
+
+Aucun adapter productif `Transport DTO -> common` n'est ajouté. `TR-C2` reste Worker-owned et `pre.007` reste le premier point où la crate Worker concrète peut apparaître.
+
+## Version
+
+```text
+workspace.package.version = 0.3.10-pre.6
+Cargo.toml header          = 499
+workspace members          = 20
+```
+
+## Common wire Legacy/V0/V1
+
+`ksp-raw-transaction-lib` ajoute un modèle source-neutral :
+
+```text
+RawSolanaMessageVersion
+RawSolanaMessageHeader
+RawSolanaCompiledInstruction
+RawSolanaAddressTableLookup
+RawSolanaTransactionConfig
+RawSolanaTransactionMessage
+RawSolanaTransactionWire
+```
+
+et deux serializers :
+
+```text
+serialize_solana_transaction_wire
+serialize_solana_transaction_wire_base64
+```
+
+Legacy et V0 conservent le layout signatures-first existant. V1 suit SIMD-0385 : `0x81`, header, config mask, lifetime, compteurs, adresses, valeurs config, headers/payloads d'instructions et signatures terminales.
+
+Les gardes V1 verrouillent notamment :
+
+```text
+transaction <= 4096 bytes
+1..=12 signatures
+<= 64 adresses
+<= 64 instructions
+num_readonly_signed < num_required_signatures
+indexes programme/comptes bornés
+aucune Address Lookup Table
+aucune adresse dupliquée
+config présente, y compris vide
+aucun trailing byte après les signatures
+```
+
+Les goldens couvrent Legacy, V0, V1 configuration complète et V1 configuration vide.
+
+## Extraction de signature V1
+
+`extract_raw_transaction_signature_from_binary_base64` distingue désormais :
+
+```text
+premier octet == 0x81 -> parser V1 et signatures terminales
+sinon                 -> parser short-vector signatures-first Legacy/V0
+```
+
+Le parser V1 parcourt structurellement mask/config, adresses, headers, payloads et signatures et exige la fin exacte du wire.
+
+## Parité Yellowstone
+
+`crates/ksp-job-backfill-lib/tests/yellowstone_raw_parity.rs` monte un serveur Geyser local déterministe, ouvre le vrai `YellowstoneGrpcChannel::open_standard_subscribe` puis reçoit :
+
+```text
+SubscribeUpdateTransaction V1
+SubscribeUpdateBlock V1 portant la même transaction
+```
+
+La projection vers `RawSolanaTransactionWire` est strictement test-only. Le canari exige le même wire V1 exact pour les deux updates et vérifie slot, transaction index et `block_time` côté Block.
+
+## Qualification RAW
+
+Le gate ferme volontairement une qualification partielle :
+
+```text
+Yellowstone transaction wire = direct/fiable
+Yellowstone Transaction RAW  = hydration HTTP obligatoire : block_time absent
+Yellowstone Block RAW complet= hydration HTTP obligatoire : meta JSON byte-identical non prouvée
+```
+
+Aucun champ manquant n'est inventé et aucune projection protobuf -> JSON ad hoc n'est introduite pour forcer un hash RAW identique.
+
+## Dependency firewall
+
+Le Backfill ajoute uniquement en dev :
+
+```text
+tonic = { workspace = true, features = ["codegen", "server"] }
+yellowstone-grpc-proto = { workspace = true, features = ["tonic"] }
+```
+
+`dependency_boundary.rs` verrouille leur absence des dépendances production et `hardening.rs` recalibre le set dev exact. Les dépendances normales restent inchangées.
+
+Il n'existe toujours aucun edge productif :
+
+```text
+ksp-onchain-transport-lib -> ksp-raw-transaction-lib
+ksp-raw-transaction-lib -> ksp-onchain-transport-lib
+```
+
+## Fraîcheur externe revalidée
+
+Revalidation le 2026-09-07 :
+
+```text
+SIMD-0385 : Transaction V1, status Review, version byte 129, signatures terminales, sans ALT
+Solana Transaction V1 examples : capacité Yellowstone avec Message.config ; activation cluster encore feature-gated/pre-release
+```
+

+# Delta `0.3.10-pre.007` — gate technique final RAW commune / cross-source
+
+## 1. Base requise
+
+```text
+0.3.10-pre.006-fix.002 appliquée
+workspace.package.version = 0.3.10-pre.6.fix.2
+```
+
+Le rejeu opérateur communiqué le 8 septembre 2026 ferme entièrement `pre.006-fix.002` : audits Rust/Markdown, `cargo check --workspace`, Clippy workspace `--all-targets --all-features -- -D warnings`, puis les suites `ksp-raw-transaction-lib`, `ksp-onchain-transport-lib` et `ksp-job-backfill-lib` sont PASS.
+
+Les smokes réseau Transport opt-in restent `ignored` par politique ; aucun succès live n'est revendiqué à partir de ces tests non exécutés.
+
+## 2. Objet
+
+Ouvrir exclusivement le gate technique final de `0.3.10` sans nouveau développement fonctionnel et sans effectuer la réconciliation documentaire réservée à `pre.008`.
+
+Cette tranche fige l'état à tester sous l'identifiant :
+
+```text
+0.3.10-pre.7
+```
+
+Le gate vert de `pre.006-fix.002` est une précondition. Il ne remplace jamais la preuve finale sur cette version exacte.
+
+## 3. Version
+
+Cette livraison est une prerelease non-fix. Conformément à la politique de version KSP :
+
+```text
+workspace.package.version = 0.3.10-pre.7
+commit attendu            = v0.3.10-pre.007
+aucun tag prerelease
+```
+
+Aucune version npm/Tauri n'est modifiée.
+
+## 4. Périmètre
+
+Aucun changement de code métier, API, golden RAW, dépendance, feature, Config, Store, Transport, Backfill ou frontend.
+
+Le seul ajustement de validation corrige une référence devenue obsolète après le redécoupage de `pre.006` : `ksp-worker-raw-transaction-ingest-lib` n'existe pas dans `0.3.10` et appartient désormais à `0.3.11`. Le gate final utilise donc les graphes réellement pertinents de la common RAW et du Backfill.
+
+## 5. Gate déterministe final
+
+À exécuter séquentiellement sur `0.3.10-pre.7` :
+
+```bash
+cargo fmt --all -- --check
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas

+cargo tree -p ksp-job-backfill-lib --edges dev
+cargo tree -p ksp-job-backfill-lib -e features
+cargo tree --duplicates
+```
+
+Le gate est séquentiel : tout échec bloque `pre.007`, même si des commandes suivantes réussissent. Un défaut découvert ouvre `pre.007-fix.NNN` avant toute poursuite vers `pre.008`.
+
+## 6. Non-claims live
+
+Cette tranche n'ajoute aucun nouveau smoke réseau. Les smokes déjà présents restent opt-in selon leurs politiques respectives. En particulier, un test `ignored` n'est pas déclaré PASS live.
+
+La qualification déterministe acquise reste inchangée :
+
+```text
+HTTP / WS standard / Helius / Yellowstone : preuves fixture/parité existantes
+Yellowstone RAW complet                  : hydration HTTP conservée selon qualification actuelle
+Helius transactionSubscribe RAW complet  : hydration HTTP conservée selon qualification actuelle

+
+Corriger les dernières survivances actives de l'ancienne notation des couches de données découvertes pendant la préparation de `pre.009`, sans les absorber dans le couloir de publication.

+
+Les occurrences où `N1–N4` désignent réellement les niveaux architecturaux restent inchangées.
+
+### `docs/architecture/011-RAW_TRANSACTION_ACQUISITION.md`

+workspace.package.version = 0.3.10-pre.7

+réconcilie les règles et documents d'architecture actifs ;
+complète la documentation durable de ksp-raw-transaction-lib ;
+ne modifie aucun comportement Rust, API, dépendance, feature ou runtime.
+```
+
+## 3. Version
+
+Cette livraison est une prerelease non-fix :
+
+```text
+workspace.package.version = 0.3.10-pre.8
+commit attendu            = v0.3.10-pre.008
+aucun tag prerelease
+```
+
+Aucune version npm/Tauri n'est modifiée.
+
+## 4. Nomenclature canonique des couches de données
+
+La progression durable du Store devient :
+
+```text
+D1 RAW -> D2 STRUCTURAL -> D3 DECODED -> D4 DOMAIN
+```
+
+Sémantique :
+
+```text
+D1 RAW        = matériau acquis et conservé avant décomposition métier ;
+D2 STRUCTURAL = décomposition Solana générique en structures unitaires exploitables ;
+D3 DECODED    = décodage générique des structures selon les contrats de programmes ;
+D4 DOMAIN     = matérialisation métier/spécialisée issue des données décodées.
+```
+
+L'ancien nom de couche D2 `CORE` est abandonné. Il créait une ambiguïté avec `ksp-core-lib` et le domaine Core fondamental alors que cette couche Store représente une décomposition structurelle du RAW.
+
+Cette normalisation ne renomme jamais :
+
+```text
+ksp-core-lib ;
+le domaine Core architectural fondamental ;
+les noms propres comme « Solana Core Programs » ;
+les traces historiques clôturées qui documentent l'ancienne terminologie.
+```
+
+Les niveaux architecturaux `N1–N4` de `docs/architecture/002-LAYERS_AND_DEPENDENCIES.md` restent réservés aux niveaux de composants. Les couches de données utilisent désormais `D1–D4` afin d'éviter toute collision de vocabulaire. Les plans Store historiques qui parlaient de N1–N4 data restent interprétables selon la correspondance ci-dessus mais ne sont pas réécrits en masse.
+
+## 5. Conséquences STRUCTURAL
+
+Les rôles actifs deviennent explicitement :
+
+```text
+STRUCTURAL persistence
+RAW -> STRUCTURAL replay/backfill
+STRUCTURAL job
+STRUCTURAL worker
+STRUCTURAL inspection/control app lorsque pertinent
+```
+
+Le `STRUCTURAL job` est borné et rejouable. Le `STRUCTURAL worker` traite continuellement le backlog RAW. Aucun des deux ne réalise le décodage Program : la frontière `STRUCTURAL -> DECODED` reste en aval.
+
+## 6. Séquence fonctionnelle active
+
+`docs/plans/002-FUNCTIONAL_RELEASE_SEQUENCE.md` est remis en cohérence avec la trajectoire réellement matérialisée :
+
+```text
+0.3.1          ksp-store-api RAW
+0.3.2          Store runtime + backend PostgreSQL foundation
+0.3.3          persistence RawTransaction
+0.3.4          persistence RawAccountState
+0.3.5          Interface acquisition events
+0.3.6          ksp-job-api + RawTransaction Backfill
+0.3.7          ksp-app-backfill-desk
+0.3.8          ksp-app-store-desk RAW
+0.3.9          ksp-worker-api + audit acquisition RawTransaction
+0.3.10         common ksp-raw-transaction-lib + preuves cross-source
+0.3.11-0.3.14 Worker RAW ingest découpé par responsabilité
+0.3.15         ksp-app-raw-transaction-ingest-desk
+0.3.16         Backfill multi-source / multi-stratégie
+```
+
+Le redécoupage ne change pas les frontières Job/Worker arrêtées précédemment et ne réintroduit aucun Worker concret dans `0.3.10`.
+
+## 7. Documentation de `ksp-raw-transaction-lib`
+
+La crate common RAW étant désormais une bibliothèque complétée de `0.3.10`, elle reçoit :
+
+```text
+crates/ksp-raw-transaction-lib/README.md
+crates/ksp-raw-transaction-lib/USAGE.md
+```
+
+Le `README.md` fixe son rôle, ses dépendances autorisées et ses frontières. Le `USAGE.md` reste volontairement version-neutre et montre uniquement l'utilisation durable de la surface publique de crate root : signatures, wire Solana, canonicalisation RAW et assemblage acquisition/observation.
+
+La documentation rappelle explicitement que le résultat de cette crate reste D1 RAW et qu'elle n'implémente pas la transformation RAW -> STRUCTURAL.
+
+## 8. ROADMAP et publication
+
+`ROADMAP.md` est modifié uniquement pour éliminer l'ancien libellé actif `RAW/CORE/DECODE/SPECIALIZED` au profit de `RAW/STRUCTURAL/DECODED/DOMAIN`.
+
+Les changements de statut de release, le CHANGELOG et la préparation du prompt `0.3.11` restent réservés à `pre.009`.
+
+## 9. Traces historiques
+
+Les prompts, deltas, plans et validations clôturés ne sont pas réécrits en masse. Une ancienne occurrence de `CORE` dans une trace historique peut donc rester légitime lorsqu'elle décrit l'état documentaire de sa livraison.
+
+Cette tranche corrige les documents durables actifs, pas l'histoire du repository.
+
+## 10. Fichiers modifiés

+contrôle statique version/scope/headers
+contrôle exact de l'inventaire delta

+```
+
+Cargo/rustc/rustfmt ne sont pas disponibles dans l'environnement d'assemblage ; aucun gate Cargo de `pre.008` n'est déclaré PASS localement. Le gate technique complet de `pre.007` reste la baseline opérateur fermée ; `pre.008` ne modifie aucun code ni graphe de dépendances.
+
+## 13. Rejeu opérateur `pre.008`
+
+Comme cette tranche est documentaire hors incrément mécanique de version workspace, le rejeu minimal attendu est :
+
+```bash
+cargo fmt --all -- --check
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas

+cargo clippy --workspace --all-targets --all-features -- -D warnings
+```
+
+Un échec ouvre `pre.008-fix.NNN`. Aucun nouveau test fonctionnel ou smoke live n'est requis par cette réconciliation documentaire seule.
+
+## 14. Suite

+
+## 2. Objet
+
+Préparer exclusivement la publication stable de `0.3.10` après fermeture technique `pre.007` et réconciliation documentaire `pre.008` + `pre.008-fix.001`.

+```
+
+Le header du `Cargo.toml` racine passe de `503` à `504`.
+
+## 4. CHANGELOG
+
+`CHANGELOG.md` reçoit la synthèse stable de `0.3.10` :
+
+```text

+handoff 0.3.11
+```
+
+Aucune nouvelle preuve live n'est inventée par la synthèse.
+
+## 5. ROADMAP
+
+`ROADMAP.md` marque `0.3.10` comme réalisé et remplace son texte prospectif par le résultat effectivement livré. Les releases `0.3.11` à `0.3.16` restent prévues et conservent leurs frontières déjà réconciliées.
+
+Aucune autre réconciliation documentaire n'appartient à cette tranche.
+
+## 6. Prompt `0.3.11`
+
+Ajout :
+
+```text
+prompts/030-V0_3_11_START_PROMPT.md
+```
+
+Le prompt ouvre `0.3.11` uniquement depuis `v0.3.10` et impose un `pre.001` audit/brainstorming/sizing avant codage lourd.
+
+Mission initiale à réauditer :
+
+```text
+ksp-worker-raw-transaction-ingest-lib
+crate/dependency firewall

+handle/start-stop/lifecycle
+supervisor privé
+channels bornés
+pipeline déterministe common RAW -> Store
+persistence/deduplication/content conflict
+snapshots latest-value sûrs
+hardening runtime de fondation
+```
+
+Aucune voie Yellowstone/WS/Helius/HTTP live complexe n'est requise pour fermer `0.3.11`. Le prompt impose de rescinder la release avant implémentation si son sizing réel ne tient pas dans une session.

+tests
+Config / schemas

+Markdown table audit: clean (340 table(s), 771 file(s))
+contrôle du scope: exactement cinq fichiers ajoutés/modifiés
+unzip -t: PASS
+reconstruction overlay: 1713 fichiers, 0 différence byte
+```
+
+Cargo/rustc/rustfmt ne sont pas disponibles dans l'environnement d'assemblage ; aucun gate Rust local n'est déclaré PASS.
+
+## 12. Validation opérateur attendue
+
+```bash
+cargo fmt --all -- --check
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates deltas
+cargo check --workspace
+```
+
+Comme la tranche ne change aucun code ni dépendance, ce gate de publication reste volontairement minimal. Un échec ouvre `pre.009-fix.NNN` seulement s'il relève du CHANGELOG, ROADMAP, prompt ou de la mécanique de publication ; une anomalie de code/documentation durable antérieure retourne dans son couloir propre.
+
+## 13. Décisions prises
+
+```text
+0.3.10 est fermé fonctionnellement autour de la common RAW et de ses preuves cross-source
+le Worker concret commence en 0.3.11
+0.3.11 n'exige aucune source live complexe pour sa clôture
+pre.001 de 0.3.11 doit re-sizer la release avant codage lourd
+D1/D2/D3/D4 et STRUCTURAL restent la terminologie durable des couches Store
+```
+
+## 14. Questions ouvertes
+
+Aucune question de `0.3.10` ne doit être résolue dans `pre.009`. Les choix exacts de runtime/settings/supervisor/harness du Worker sont transférés au gate `0.3.11-pre.001`.
+
+## 15. Suite
+
+Si le gate opérateur de cette tranche est vert :
+
+```text
+0.3.10-rel.001
+```
+
+doit rester une publication stable mécanique : version Cargo finale `0.3.10`, delta `rel.001`, commit de release puis tag stable `v0.3.10`, sans rattrapage fonctionnel ou documentaire.

+
+## Surface stable publiée
+
+`0.3.10` stabilise `ksp-raw-transaction-lib` comme lower-layer D1 RAW source-neutral commune aux producteurs `RawTransaction` :
+
+- canonicalisation RAW v1 commune extraite du Backfill sans changement des golden bytes/hash ;
+- construction de `RawTransaction` et `RawTransactionObservation` via les modèles backend-neutral de `ksp-store-api` ;
+- identité canonique `(network, signature)` et observations producteur séparées ;
+- wire Solana source-neutral Legacy/V0/V1, sérialisation Base64 et extraction de signature depuis le matériau transactionnel complet ;
+- dépendances volontairement limitées, sans Transport, Config, runtime async, Job, Worker, `ksp-store-lib` ni backend Store physique ;
+- migration de `ksp-job-backfill-lib` vers la common crate sans edge Job vers Worker.
+
+La release stabilise aussi la qualification cross-source préparatoire au futur Worker :
+
+- `ksp-onchain-transport-lib::get_block_observed` conserve l'identité sûre de la route HTTP réellement gagnante ;
+- `blockSubscribe` standard `full/base64` est qualifié comme RAW-direct sur le sous-ensemble déterministe prouvé ;
+- Helius `transactionSubscribe` reste un signal nécessitant hydration HTTP lorsque les métadonnées indispensables manquent ;
+- Yellowstone Transaction V1 qualifie le wire source-neutral ; Transaction nécessite hydration HTTP pour le `block_time` ;
+- Yellowstone Block conserve le `block_time`, mais le RAW complet reste conservateur tant que la meta protobuf n'est pas prouvée byte-identical à la meta JSON HTTP ;
+- aucun RAW-direct Yellowstone complet ni feed EARLY n'est revendiqué sans preuve.
+
+La nomenclature durable des couches Store est désormais :
+
+```text
+D1 RAW
+D2 STRUCTURAL
+D3 DECODED
+D4 DOMAIN
+```
+
+`N1–N4` restent réservés aux niveaux architecturaux. Le terme `CORE` n'est plus le nom de la couche Store D2 ; `ksp-core-lib` et les usages réellement liés au Core fondamental restent inchangés.
+
+Le runtime Worker concret est volontairement hors de `0.3.10`. La trajectoire stabilisée devient :
+
+```text
+0.3.11 fondation runtime/persistence déterministe du Worker RawTransaction ingest
+0.3.12 Yellowstone + hydration HTTP + continuité
+0.3.13 WS standard / Helius / HTTP live + convergence multi-source
+0.3.14 gap repair / hardening / smokes provider accessibles
+0.3.15 ksp-app-raw-transaction-ingest-desk
+0.3.16 Backfill multi-source / multi-stratégie
+```
+
+Le Job Backfill historique paramétré et le Worker Ingest continu restent deux producteurs indépendants du même Store.
+
+## Suite préparée
+
+La session suivante part exclusivement de la base stable :
+
+```text
+v0.3.10

+
+et exécute :

+```text
+0.3.11 — fondation runtime du Worker RawTransaction ingest

+
+`0.3.11-pre.001` doit commencer par lecture, audit, brainstorming, sizing et planification avant toute implémentation lourde. Si le périmètre n'est pas clôturable dans une seule session ou si une tranche dépasse le budget prévu, la release doit être rescindée avant le développement lourd.

+
+L'audit mécanique était vert mais la lecture humaine des règles a trouvé deux divergences normatives actives non détectées par les scripts.
+
+## Objectif
+
+Exécuter intégralement le gate d'ouverture demandé par `prompts/030-V0_3_11_START_PROMPT.md` : lecture/audit de la stable `v0.3.10`, contrôle renforcé des règles, inventaire Worker/Common RAW/Store/Backfill, fraîcheur des dépendances runtime, brainstorming public/private et supervisor, définition du harness déterministe, threat model, sizing et planification, sans commencer l'implémentation lourde du Worker.
+
+## Réconciliation normative
+
+### D1–D4
+
+Défauts hérités trouvés :

+KSP-DURABLE-002 : D2 encore nommé Core canonique
+KSP-DURABLE-006 : instructions encore qualifiées de faits Core
+DEP-STORE-004 : D2 encore nommé Core canonique
+```
+
+Les règles plus récentes et l'architecture `008` imposent déjà :
+
+```text
+D1 RAW
+D2 STRUCTURAL
+D3 DECODED
+D4 DOMAIN
+```
+
+Correction : normalisation des trois règles actives. Les archives/deltas/plans historiques ne sont pas réécrits.
+
+### Nom du Worker RAW
+
+Les règles `KSP-WORKER-005/006/007/010` utilisaient encore :
+
+```text
+ksp-worker-raw-retriever
+```
+
+Le nom durable retenu par les architectures, ROADMAP, CHANGELOG, handoff `0.3.10` et prompt `030` est :
+
+```text
+ksp-worker-raw-transaction-ingest-lib
+```
+
+Correction : normalisation du nom dans ces quatre règles, sans changement de leur responsabilité fonctionnelle.
+
+Un scan des règles actives après correction ne trouve plus `D2 Core canonique`, `faits Core distincts` ni `ksp-worker-raw-retriever`.
+
+## Inventaire et décisions de fondation

+Store reste vérité de convergence (network, signature)
+Backfill et Worker restent producteurs indépendants

+pre.010 public/release/security hardening
+pre.011 gate technique final
+pre.012 réconciliation documentaire

+```
+
+Décision : `0.3.11` reste clôturable dans une seule session **à condition** de ne pas introduire source live, Transport productif, Config, migration Store ou continuity/gap repair. Toute tranche réellement trop grosse est scindée avant exécution.

+
+Un scan sémantique complémentaire des règles actives confirme l'absence des trois formulations obsolètes corrigées. La comparaison byte-à-byte contre la stable confirme exactement 3 fichiers ajoutés, 3 fichiers modifiés et aucun fichier supprimé.
+
+## Preuve opérateur stable distincte
+
+Le journal opérateur fourni pour `0.3.10` montre :
+
+```text
+cargo fmt --all -- --check : sans erreur
+cargo check --workspace : sans erreur
+cargo clippy --workspace --all-targets --all-features -- -D warnings : sans erreur
+ksp-raw-transaction-lib : 26 tests verts
+ksp-job-backfill-lib : 77 tests verts
+cargo tree normal des deux crates : fourni
+```
+
+Cette preuve concerne la stable d'entrée ; elle ne devient pas une exécution locale de `0.3.11-pre.001`.

+
+Motif : `cargo` n'est pas installé dans l'environnement d'assemblage. `pre.001` ne contient aucun Rust Worker, mais l'opérateur doit rejouer les gates applicables après application du delta.

+# Delta `0.3.11-pre.002` — squelette Worker RAW + dependency firewall
+
+## Base requise
+
+```text
+0.3.11-pre.001
+workspace.package.version = 0.3.11-pre.1
+```
+
+Le gate opérateur communiqué pour `pre.001` est vert sur `cargo fmt --all`, les audits Rust/Markdown, `cargo check --workspace` et Clippy workspace strict `--all-targets --all-features -- -D warnings`. Aucun `cargo test` supplémentaire n'a été communiqué pour ce gate et aucun n'est inventé.
+
+## Objectif
+
+Créer uniquement le squelette de `ksp-worker-raw-transaction-ingest-lib`, l'inscrire au workspace et verrouiller son graphe de dépendances. Aucun settings, identity, `start`, task, channel, Store write, canonicalisation ou snapshot runtime n'est matérialisé dans cette tranche.
+
+## Version
+
+Cette tranche est une prerelease non-fix :
+
+```text
+workspace.package.version = 0.3.11-pre.2
+```
+
+Le `Cargo.toml` racine passe du header `506` au header `507` et le workspace passe de 20 à 21 membres.
+
+## Graphe de production exact
+
+```text
+ksp-worker-raw-transaction-ingest-lib
+    -> ksp-core-lib
+    -> ksp-logging-lib
+    -> ksp-raw-transaction-lib
+    -> ksp-store-lib default-features=false
+    -> ksp-worker-api
+    -> sha2
+    -> tokio features=macros,rt,sync,time
+```
+
+Ces edges matérialisent uniquement la frontière décidée en `pre.001`. Le code runtime qui les consommera reste réservé à ses tranches dédiées.
+
+## Firewall explicite
+
+Absents du manifest de production :
+
+```text
+futures-util
+ksp-config-lib
+ksp-interface-lib
+ksp-job-api
+ksp-job-backfill-lib

+ksp-store-postgres-lib
+ksp-wallet-lib
+reqwest
+Solana protocol SDK direct
+tokio-tungstenite
+tonic
+yellowstone-grpc-proto
+```
+
+Il n'existe ni `[dev-dependencies]`, ni `[build-dependencies]` dans cette tranche.
+
+## Crate-root volontairement vide de comportement
+
+`src/lib.rs` contient uniquement les lints workspace et la rustdoc de responsabilité. Il n'expose encore :
+
+```text
+aucun pub mod
+aucun type public
+aucune fonction publique
+aucun start/spawn
+aucun appel Tokio
+aucun appel Store/common RAW/Worker API
+```
+
+Le test externe `dependency_boundary.rs` verrouille le manifest exact, les edges interdits et l'absence de comportement runtime prématuré au crate-root.
+
+## Documentation volontairement différée
+
+`README.md` et `USAGE.md` ne sont pas créés à ce stade car la crate ne possède encore aucune API consommable. Leur réconciliation version-neutral reste réservée à `pre.012`, après freeze de la fondation runtime.

+```
+
+## Défaut opérateur constaté
+
+Le gate opérateur du 8 septembre 2026 confirme que `cargo fmt --all`, les audits Rust/Markdown et `cargo check --workspace` passent, mais `cargo clippy --workspace --all-targets --all-features -- -D warnings` rejette deux usages de l'opérateur `?` dans `RawTransactionIngestSettings::new`.

+clippy::question_mark_used
+```
+
+La règle normative `RUST-ERR-002` interdit également l'opérateur `?` en code de production. Les tests de la crate communiqués dans le même journal restent verts : 4 tests unitaires, 3 tests dependency-boundary et 3 tests public API, sans échec.
+
+## Objectif
+
+Corriger strictement `pre.003` sans modifier son contrat fonctionnel : remplacer les deux propagations `?` par un contrôle de flux explicite retournant exactement la même erreur. Aucun type, borne, default, code d'erreur, dépendance, test, lifecycle ou comportement runtime n'est ajouté.
+
+## Version
+
+Le correctif touche un fichier Rust de production. Conformément à `VER-ID-007` et `VER-ID-010` :

+
+## Base requise
+
+```text
+0.3.11-pre.002
+workspace.package.version = 0.3.11-pre.2
+```
+
+Le gate opérateur communiqué pour `pre.002` est entièrement vert : `cargo fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, tests de la crate et arbres Cargo normal/features. Les 3 tests `pre.002` passent et le firewall de dépendances reste conforme.
+
+## Objectif
+
+Matérialiser uniquement l'identité de la verticale Worker RAW transaction ingest et ses settings runtime techniques bornés. Aucun lifecycle, `start`, spawn, task, channel, supervisor, persistence Store, canonicalisation ou source live n'est introduit.
+
+## Version
+
+Cette tranche est une prerelease non-fix :
+
+```text
+workspace.package.version = 0.3.11-pre.3
+```
+
+## Identité Worker
+
+La verticale possède le code stable :
+
+```text
+RAW_TRANSACTION_INGEST_WORKER_KIND_CODE = "raw_transaction_ingest"
+```
+
+La transformation de ce texte en `WorkerKindCode` reste sous validation de `ksp-worker-api`; aucun second validateur d'identité n'est créé dans la crate concrète.
+
+## `RawTransactionIngestSettings`
+
+Surface exacte :
+
+```text
+network: ksp_store_lib::RawNetworkId
+worker_id: ksp_worker_api::WorkerId
+admission_queue_capacity: usize
+persistence_concurrency: usize
+shutdown_drain_timeout: Duration
+```
+
+Les champs sont privés et exposés par getters. Deux constructions existent : paramètres explicites bornés et defaults V1 sur des identités déjà validées.
+
+Bornes exactes :
+
+```text
+admission queue : 1..=65_536, default 256
+persistence concurrency : 1..=64, default 8
+shutdown drain : 100 ms..=30 s, default 5 s
+```
+
+Les bornes sont inclusives. Aucun champ historique, provider-specific, retry, replay, gap repair, source capability ou frontier n'est ajouté.
+
+## Erreur settings
+
+La crate ouvre un seul code propre à cette tranche :
+
+```text
+worker_raw_transaction_ingest.settings_invalid
+```
+
+Il couvre uniquement les limites techniques possédées par le Worker concret. Le contexte d'erreur contient seulement le nom statique du champ invalide :
+
+```text
+admission_queue_capacity
+persistence_concurrency
+shutdown_drain_timeout
+```
+
+Aucune valeur caller-supplied n'est copiée dans le diagnostic.
+
+Les erreurs de `RawNetworkId`, `WorkerId` et `WorkerKindCode` restent celles de leurs crates propriétaires.
+
+## Redaction
+
+`Debug` du settings rend le network logique mais conserve le `WorkerId(..)` redacted fourni par `ksp-worker-api`; le texte réel du Worker ID n'est pas rendu.
+
+## Frontière runtime maintenue

+workspace.package.version = 0.3.11-pre.3.fix.1

+
+Le gate opérateur du 8 septembre 2026 est vert après le fix `pre.003-fix.001` sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict et les dix tests de la crate Worker.
+
+## Objectif
+
+Matérialiser uniquement la responsabilité `pre.004` du plan `032` : start synchrone sur runtime Tokio caller-owned, handle clonable, stop idempotent, lifecycle générique `ksp-worker-api` et future terminal boxed, sans ouvrir le supervisor de tâches enfants, l'admission, la canonicalisation, la persistence, les snapshots concrets ou une source live.
+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.004
+workspace.package.version : 0.3.11-pre.4
+```
+
+## Contrat public ajouté
+
+```text
+ERROR_CODE_RAW_TRANSACTION_INGEST_RUNTIME_INVALID
+RawTransactionIngestWorker
+RawTransactionIngestHandle
+RawTransactionIngestTerminalFuture
+RawTransactionIngestWorker::start(settings, Arc<Store>)
+RawTransactionIngestHandle::request_stop()
+RawTransactionIngestHandle::wait_terminal()
+```
+
+`start` exige un runtime Tokio courant, vérifie le réseau du Store avant spawn et conserve le Store par `Arc` sans le fermer ni l'utiliser encore pour une écriture.
+
+`request_stop()` partage `WorkerStopToken` et retourne `true` uniquement lors de la première demande acceptée. Le task racine est réveillé par un `watch<bool>` privé ; la disparition de tous les handles ferme ce channel et provoque également une terminaison coopérative.
+
+`wait_terminal()` retourne une future boxed `Send`. Elle attend un `WorkerState` terminal puis la fermeture du sender d'état par le task racine ; aucun `JoinHandle` public n'est nécessaire.
+
+## Lifecycle de fondation
+
+```text
+Starting -> Running -> Stopping -> Stopped
+Starting -> Stopping -> Stopped  si stop immédiat
+```
+
+Les transitions utilisent `WorkerLifecycle`. Un invariant impossible devient `Faulted(worker_raw_transaction_ingest.runtime_invalid)` sans payload, worker id, réseau ou erreur externe dans le diagnostic.
+
+## Hors scope conservé
+
+```text
+JoinSet / tasks enfants
+mpsc / admission
+canonicalisation common RAW
+observation key
+persistence Store
+snapshots concrets / WorkerSnapshotSource
+source live / Transport
+Config
+```
+
+Les méthodes de snapshot prévues par la surface finale restent différées à `pre.008`. `pre.005` introduit le supervisor et l'ownership des tâches enfants autour du wake-up de stop déjà minimalement nécessaire ici.
+
+## Tests ajoutés ou étendus
+
+Les tests couvrent statiquement ou via harness runtime privé :
+
+```text

+# Delta `0.3.11-pre.005` — supervisor privé et ownership des tâches
+
+## Base requise
+
+```text
+0.3.11-pre.004
+workspace.package.version = 0.3.11-pre.4
+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, les 16 tests de la crate Worker, doc-tests et les arbres Cargo normal/features.
+
+## Objectif
+
+Matérialiser uniquement la responsabilité `pre.005` du plan `032` : supervisor privé, `JoinSet` privé, ownership et join des tâches enfants, intégration du stop au seam source déterministe et preuve qu'aucune tâche enfant coopérative ne survit au terminal. Aucun admission `mpsc`, aucune canonicalisation RAW et aucune persistence Store réelle.
+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.005
+workspace.package.version : 0.3.11-pre.5
+```
+
+## Runtime privé ajouté
+
+Le task racine devient le supervisor du run. Il possède un `tokio::task::JoinSet<()>` privé et un seam privé de spawn de tâches source.
+
+La production appelle ce seam sans source. Les tests injectent des tâches déterministes qui reçoivent un clone du `watch<bool>` de stop.
+
+Le supervisor :
+
+```text
+reap des enfants terminés via join_next()
+stop prioritaire via select! biased
+join de tous les enfants restants après stop/fermeture du contrôle
+Stopped publié uniquement après join complet
+JoinError -> supervision non clean ; Faulted à la fermeture de supervision
+```
+
+Aucun `JoinHandle` ou `JoinSet` n'est ajouté à la surface publique.
+
+## Arrêt coopératif
+
+Le timeout de drain configuré existe déjà dans les settings mais n'est pas encore appliqué ici. `pre.005` attend coopérativement les enfants ; le timeout, `abort_all` et les races stop/fault sont réservés au hardening `pre.009`.
+
+## Hors scope conservé
+
+```text
+mpsc / admission
+PrivateRawTransactionIngress
+canonicalisation common RAW
+observation key
+persistence Store
+snapshots concrets / WorkerSnapshotSource
+source live / Transport
+Config
+abort/timeout de drain
+```
+
+## Tests ajoutés ou étendus
+
+```text
+supervisor joint trois tâches source coopératives avant Stopped
+compteur d'enfants actifs == 0 au terminal
+reap d'une source terminée pendant Running
+join d'une source encore active lors du stop

+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, les 18 tests de la crate Worker, doc-tests et les arbres Cargo normal/features.
+
+## Objectif
+
+Matérialiser uniquement la responsabilité `pre.006` du plan `032` : admission `mpsc` centrale bornée, backpressure async, ingress privé, canonicalisation via `ksp-raw-transaction-lib`, observation key Worker déterministe et assembly du `RawTransactionAcquisition`.

+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.006

+```
+
+## Admission privée bornée
+
+Le supervisor crée un seul channel central dimensionné par `RawTransactionIngestSettings::admission_queue_capacity()` :
+
+```text
+tokio::sync::mpsc::channel(...)
+```
+
+Le seam source reçoit le sender `mpsc` borné et le signal de stop. Le contrat prouvé est :
+
+```text

+select! biased : stop avant send dans le harness source
+aucun unbounded_channel
+receiver close au shutdown
+```
+
+Au shutdown, le receiver ferme les nouvelles admissions et consume les entrées déjà en queue avant le join final des tâches enfants.
+
+## Ingress et Common RAW
+
+L'ingress crate-private, absent de l'API publique, transporte :
+
+```text
+RawTransactionMaterial
+RawNetworkId attendu
+RawAcquisitionProvenance
+source key opaque [u8; 32]
+```
+
+Le pipeline est :
+
+```text
+network guard
+ksp_raw_transaction_lib::canonicalize_raw_transaction(...)
+material network guard
+observation key Worker
+ksp_raw_transaction_lib::assemble_raw_transaction_acquisition(...)
+```
+
+Aucune canonicalisation RAW v1 n'est réimplémentée dans le Worker.
+
+## Observation key V1
+
+Domaine exact :
+
+```text
+ksp.raw_transaction_ingest.observation.v1\0
+```
+
+Le SHA-256 encode avec longueur `u64` big-endian :

+## Base requise
+
+```text
+0.3.11-pre.006-fix.001
+workspace.package.version = 0.3.11-pre.6.fix.1
+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, les 22 tests de la crate Worker et les doc-tests. Aucun `cargo tree` n'a été rejoué après le fix, celui-ci n'ayant modifié aucune dépendance ni feature.
+
+## Objectif
+
+Matérialiser uniquement la responsabilité `pre.007` du plan `032` : persistence atomique via la façade Store, mode `Normal`, concurrence bornée, classification entity/observation, idempotence/purge et terminaux dédiés content conflict/Store failure. Aucun snapshot concret et aucune source réseau.
+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.007
+workspace.package.version : 0.3.11-pre.7
+```
+
+## Port Store privé
+
+La crate ajoute un port `RawTransactionIngestPersistencePort` crate-private, implémenté par `ksp_store_lib::Store` et utilisé exclusivement avec :
+
+```text
+RawTransactionWrite::persist_raw_transaction_acquisition(..., RawTransactionAcquisitionMode::Normal)
+```
+
+Aucun backend Store concret n'entre dans le graphe ou dans le code Worker.
+
+## Outcomes
+
+Classification exacte :
+
+```text
+Inserted       + Inserted       -> Inserted / Inserted
+AlreadyPresent + Inserted       -> AlreadyPresent / Inserted
+AlreadyPresent + AlreadyPresent -> AlreadyPresent / AlreadyPresent
+SkippedPurged  + NotRecorded    -> SkippedPurged / NotRecorded
+```
+
+`Rehydrated` et les couples impossibles deviennent `runtime_invalid`.
+
+## Faults Store
+
+Deux codes publics deviennent actifs :
+
+```text
+worker_raw_transaction_ingest.content_conflict
+worker_raw_transaction_ingest.store_failed
+```
+
+Le conflit Store canonique est projeté sur `content_conflict`. Toute autre erreur Store est réduite à `store_failed` en conservant uniquement son domain/code sûr, jamais son texte arbitraire.
+
+## Concurrence bornée
+
+Le supervisor possède un `JoinSet` privé de persistences et n'admet une nouvelle acquisition que lorsque :
+
+```text
+in_flight_persistence < persistence_concurrency
+```
+
+Aucune queue secondaire ou persistence non bornée n'est introduite. Le harness bloque quatre writes avec une limite de deux et exige `max_active == 2`.
+
+## Drain
+
+Sur stop ou fault : nouvelles admissions fermées, acquisitions déjà admises drainées/persistées, persistences rejointes, sources rejointes, puis terminal. Le timeout/abort et la priorité complète des races terminales restent dans `pre.009`.
+
+## Tests ajoutés ou étendus
+
+```text
+mode Normal exact
+new/idempotent/purged + observation distincte
+Rehydrated/couples impossibles rejetés
+network mismatch avant write
+content conflict redacted

+```
+
+Le code traitait une erreur de publication snapshot puis testait séparément `fault.is_none()`. Clippy exige la forme conditionnelle fusionnée.
+
+## Objectif
+
+Corriger strictement `pre.008` sans modifier son comportement : même erreur, même priorité du premier fault, mêmes snapshots, mêmes compteurs, même lifecycle et même runtime. Aucune dépendance, feature ou surface publique n'est modifiée.
+
+## Version
+
+Le correctif touche un fichier Rust de production. Conformément aux règles de version applicables aux corrections code/build :

+## Modification

+    && fault.is_none()
+{
+    fault = Option::Some(error.code());
+}

+# Delta `0.3.11-pre.008` — snapshots latest-value et projection Worker API
+
+## Base requise
+
+```text
+0.3.11-pre.007
+workspace.package.version = 0.3.11-pre.7
+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, 31 tests de la crate Worker et les doc-tests. Aucun `cargo tree` intermédiaire n'était requis : `pre.007` n'avait modifié aucune dépendance ni feature.
+
+## Objectif
+
+Matérialiser uniquement la responsabilité `pre.008` du plan `032` : snapshot concret latest-value, compteurs checked, projection directe vers `ksp-worker-api::WorkerSnapshotSource`, coalescence des listeners et terminal retenu. Aucun hardening timeout/abort et aucune source réseau.
+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.008
+workspace.package.version : 0.3.11-pre.8
+```
+
+## Snapshot concret
+
+La crate expose :
+
+```text
+RawTransactionIngestSnapshot
+RawTransactionIngestSnapshotFuture
+RawTransactionIngestSnapshotSource
+```
+
+Le snapshot contient uniquement la projection `WorkerSnapshot`, les capacités/profondeurs techniques bornées et les compteurs sûrs prévus par le plan.
+
+## Un seul flux latest-value
+
+Un unique :
+
+```text
+tokio::sync::watch::channel<RawTransactionIngestSnapshot>
+```
+
+porte l'état observable du run. Le watch terminal spécialisé des tranches précédentes disparaît : `wait_terminal()`, `snapshot_source()` et `worker_snapshot_source()` lisent tous ce même flux.
+
+`RawTransactionIngestSnapshotSource` implémente directement `ksp_worker_api::WorkerSnapshotSource`. La sequence `WorkerSnapshotSequence` est donc identique pour la vue concrète et la projection commune.
+
+## Compteurs checked
+
+Les compteurs `u64` effectivement incrémentés dans cette tranche utilisent `checked_add(1)`. Aucun wrap silencieux n'est admis. Le nouveau code public est :
+
+```text
+worker_raw_transaction_ingest.counter_exhausted
+```
+
+Les compteurs sont mis à jour au point d'ownership du supervisor : dequeue/canonicalisation et récolte de persistence. `admission_queue_depth` provient directement du receiver `mpsc` borné ; `in_flight_persistence` provient du `JoinSet` privé existant.
+
+`source_failure_total` et `backpressure_wait_total` font partie du snapshot sûr mais restent à zéro en `pre.008`; leur comportement effectif appartient à `pre.009`.
+
+## Projection common Worker
+
+Mapping de fondation :
+
+```text
+Starting                         -> health Unknown
+Running                          -> health Healthy
+Stopping / Stopped               -> conserve le dernier health non terminal
+Faulted                          -> health Unhealthy
+queue > 0 ou persistence > 0     -> activity Active
+sinon Running/Stopping/terminal  -> activity Idle
+```
+
+La state machine reste celle de `ksp-worker-api::WorkerLifecycle`.
+
+## Tests ajoutés ou étendus
+
+```text
+snapshot initial exact
+projection common/concrete même sequence
+counter exhaustion stable sans wrap
+listener lent coalescé vers la dernière valeur
+terminal latest-value retenu après fermeture publisher
+surface publique snapshot_source/worker_snapshot_source
+WorkerSnapshotSource Send + Sync
+pipeline runtime réussi -> counters exacts
+Store failure -> health Unhealthy + store_failure_total
+absence de watch terminal séparé
+absence de nouveau dependency edge

+# Delta `0.3.11-pre.009` — hardening shutdown, backpressure et races fault/stop
+
+## Base requise
+
+```text
+0.3.11-pre.008-fix.001
+workspace.package.version = 0.3.11-pre.8.fix.1
+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, 38 tests de la crate Worker et les doc-tests. Aucune dépendance/feature n'ayant changé, aucun `cargo tree` intermédiaire n'était requis.
+
+## Objectif
+
+Fermer uniquement le hardening `pre.009` du plan `032` : faults source sûrs, saturation observable, ordering stop/fault déterministe, deadline de drain, abort+join au timeout et absence de tâches orphelines. Aucune source live n'est introduite.
+
+## Version
+
+```text
+identifiant de livraison : 0.3.11-pre.009
+workspace.package.version : 0.3.11-pre.9
+```
+
+## Faults source
+
+Les tâches source privées retournent `ksp_core_lib::Result<()>`. Une erreur source ou un `JoinError` devient :
+
+```text
+worker_raw_transaction_ingest.source_failed
+```
+
+Le détail distant/provider n'est pas propagé et `source_failure_total` est incrémenté via checked-add.
+
+## Shutdown borné
+
+Le drain complet est enveloppé par `shutdown_drain_timeout`. En cas de timeout :
+
+```text
+admission.close()
+persistence.abort_all()
+sources.abort_all()
+join complet des persistences
+join complet des sources
+Faulted(worker_raw_transaction_ingest.drain_timeout)
+```
+
+Le terminal n'est donc jamais publié avant la récolte de toutes les tâches possédées.
+
+## Ordering stop/fault
+
+Le stop reste prioritaire dans le `select!`, mais un Store fault découvert pendant le drain n'est pas masqué. Un fault terminal déjà décidé n'est pas remplacé par un stop tardif. Le timeout de drain prévaut lorsqu'il empêche la clôture coopérative.
+
+## Backpressure source-neutral
+
+L'admission conserve une unique queue `mpsc` bornée. Le dequeue constate si cette queue était pleine à sa capacité configurée et incrémente `backpressure_wait_total`. Aucun drop, aucune queue secondaire et aucun `unbounded_channel` ne sont ajoutés.
+
+## Tests ajoutés ou étendus
+
+```text
+source failure terminal + compteur
+late stop ne remplace pas source_failed
+stop puis Store fault pendant drain
+saturation capacity=1 sans drop
+backpressure_wait_total observable

+Corriger uniquement cette collision de nom dans la canarie `pre.010`, sans modifier la surface publique, le runtime, les dépendances, les features ou les règles de hardening.
+
+## Version
+
+Le correctif touche un fichier Rust de test. Conformément aux règles de version applicables aux corrections code/build :
+
+```text
+identifiant de livraison : 0.3.11-pre.010-fix.001
+workspace.package.version : 0.3.11-pre.10.fix.1
+```
+
+## Modification
+
+Dans `pre_010_debug_and_settings_errors_redact_worker_identity_and_invalid_values`, la variable locale issue du premier parse est renommée de `worker_id` vers `parsed_worker_id`. La fonction helper `worker_id(...)` reste ainsi appelable pour le second identifiant de test.
+
+Aucun fichier Rust de production n'est modifié.
+
+## Fichiers ajoutés

+crates/ksp-worker-raw-transaction-ingest-lib/tests/hardening.rs
+```
+
+## Fichiers supprimés
+
+Aucun.
+
+## Dépendances
+
+Aucune dépendance ni feature n'est ajoutée, supprimée ou modifiée. Le `Cargo.toml` de la crate Worker reste identique à `pre.010`.
+
+## Gate opérateur demandé
+
+Aucun `cargo tree` n'est requis pour ce fix :

+## Base requise
+
+```text
+0.3.11-pre.009-fix.003
+workspace.package.version = 0.3.11-pre.9.fix.3
+```
+
+Le gate opérateur du 8 septembre 2026 est vert sur `fmt`, audits Rust/Markdown, `cargo check --workspace`, Clippy strict, 45 tests de la crate Worker et les doc-tests. Aucune dépendance/feature n'ayant changé, aucun `cargo tree` intermédiaire n'était requis.
+
+## Objectif
+
+Fermer uniquement le hardening externe `pre.010` du plan `032` : surface publique crate-root exacte, dépendances exactes, absence de surface historique, redaction, codes d'erreur, inventaire des modules et scans Config/secret/backend/Transport. Aucun comportement runtime n'est ajouté.

+
+```text

+24 exports publics crate-root exacts
+aucun pub mod
+présence des canaries dependency/public/hardening requises
+```
+
+Le corpus attendu après cette tranche est :

+# Delta `0.3.11-pre.012` — réconciliation documentaire finale
+
+## 1. Base requise
+
+```text
+0.3.11-pre.011
+```
+
+Le gate technique final opérateur du 8 septembre 2026 est fermé avant cette tranche : rustfmt check, audits, `cargo check`, Clippy strict, 56 tests Worker, tests workspace all-targets/all-features, arbres Cargo Worker normal/features et `cargo tree --duplicates` ont été exécutés avec succès sur `0.3.11-pre.11`.
+
+## 2. Objectif
+
+`pre.012` est le couloir de réconciliation documentaire finale de `0.3.11`.
+
+La tranche :
+
+- transforme les README/USAGE du Worker en références durables ;
+- remplace les formulations où le Worker était encore décrit comme futur ;
+- distingue explicitement la fondation source-neutral matérialisée des sources live `0.3.12+` ;
+- réaligne les graphes d'architecture sur l'absence réelle de Transport dans la fondation ;
+- ferme plan et validation sur les preuves réellement exécutées ;
+- ne finalise ni `CHANGELOG.md`, ni `ROADMAP.md`, ni le prompt `0.3.12`.
+
+## 3. Version workspace
+
+`pre.012` est documentaire mais n'est pas un fix. Le contrat Cargo KSP impose donc le bump prerelease mécanique :
+
+```text
+0.3.11-pre.11
+->
+0.3.11-pre.12
+```
+
+Aucun `Cargo.toml` de crate, edge de dépendance, feature, build setting, runtime ou configuration n'est modifié.
+
+## 4. Contrat Worker documenté
+
+La documentation durable fixe l'état actuel suivant :
+
+```text
+Worker concret ksp-worker-raw-transaction-ingest-lib
+consumer de ksp-worker-api
+settings réseau/Worker bornés
+start/stop sur runtime Tokio caller-owned
+supervision privée des tâches
+mpsc central borné et backpressure
+canonicalisation/assembly via ksp-raw-transaction-lib
+observation key déterministe
+persistence atomique via ksp-store-lib, mode Normal
+concurrence Store bornée
+snapshots latest-value concrets + WorkerSnapshotSource
+classification settings/runtime/store/content/source/counter/drain
+shutdown deadline + abort/join avant terminal timeout
+```
+
+La même documentation rend explicite ce qui n'appartient pas encore à la fondation :
+
+```text
+aucune source HTTP/WS/Yellowstone productive
+aucun edge ksp-onchain-transport-lib
+aucune lecture Config
+aucun backend Store direct
+aucune API publique enqueue/source registration
+aucun replay/gap-repair live
+aucune campagne historique/backfill
+```
+
+## 5. Graphe de dépendances réconcilié
+
+Le graphe normal Worker confirmé par `pre.011` est documenté comme :
+
+```text
+ksp-worker-raw-transaction-ingest-lib
+    -> ksp-core-lib
+    -> ksp-logging-lib
+    -> ksp-raw-transaction-lib
+    -> ksp-store-lib            # default-features = false
+    -> ksp-worker-api
+    -> sha2
+    -> tokio
+```
+
+L'edge Worker -> `ksp-onchain-transport-lib` reste réservé aux adapters live ultérieurs et n'est plus présenté comme une dépendance déjà matérialisée.
+
+## 6. Fichiers ajoutés

+crates/ksp-worker-raw-transaction-ingest-lib/USAGE.md

+

+
+## 10. Validations exécutées pendant l'assemblage
+
+Sur l'état exact destiné à l'archive :
+
+```text
+General Rust rule audit: clean
+Rust export completeness audit: 0 candidate(s)
+KSP workspace Rust rule audit: clean
+Markdown table audit: clean (340 table(s), 795 file(s))
+```
+
+La revue de diff confirme également qu'aucun fichier `src/`, test, manifest de crate, Config, `CHANGELOG.md`, `ROADMAP.md` ou prompt n'est modifié.
+
+## 11. Validations non exécutées dans l'environnement d'assemblage
+
+L'environnement d'assemblage ne dispose pas de Cargo/Rustc. Les validations Cargo propres au delta restent donc opérateur :
+
+```bash
+cargo fmt --all -- --check
+cargo check --workspace
+cargo test -p ksp-worker-raw-transaction-ingest-lib
+```
+
+Le gate technique lourd (`clippy`, workspace all-targets/all-features, arbres Cargo) n'est pas rejoué car il appartient à `pre.011` et aucun code/test/dépendance/feature n'est modifié.
+
+## 12. Décisions prises
+
+- la fondation `0.3.11` est documentée comme Worker concret utilisable pour lifecycle/observabilité, mais sans source réseau productive ;
+- l'admission reste privée : aucune API publique d'enqueue n'est inventée pour anticiper `0.3.12` ;
+- les graphes séparent l'état matériel `0.3.11` du futur edge Transport ;
+- le Job Backfill reste indépendant et historique ;
+- `pre.013` reste seule propriétaire du prompt `0.3.12`, de `CHANGELOG.md` et de `ROADMAP.md`.
+
+## 13. Questions ouvertes
+
+```text
+aucune question bloquante pour la clôture documentaire 0.3.11
+```
+
+Les choix précis de source/adapters live restent des décisions de `0.3.12+`, sans être figés par cette tranche documentaire.
