 # Changelog KSP

+## 0.3.3 — Store/PostgreSQL RawTransaction vertical slice — 2026-08-30
+
+`0.3.3` complète la première vertical slice RAW physique sur le couple `ksp-store-lib` / `ksp-store-postgres-lib` sans modifier les contrats backend-agnostic acquis dans `ksp-store-api`. `PostgresBackend` et la façade `Store` implémentent désormais les six capabilities `RawTransactionRead`, `RawTransactionWrite`, `RawTransactionObservationRead`, `RawTransactionObservationWrite`, `RawTransactionRetentionRead` et `RawTransactionRetentionWrite`. Une base PostgreSQL reste liée à un unique `RawNetworkId` par `ksp_store_identity`; le mauvais réseau est refusé avant I/O, les slots `u64` sont conservés exactement en `NUMERIC(20,0)`, et la migration logique V001 reste découpée en ressources tables/contraintes/indexes avec vérification de compatibilité du schéma effectif.
+
+La persistence canonique utilise une transaction PostgreSQL unique pour `RawTransaction + observation`, tente l'insert sous contrainte d'unicité puis compare le contenu réel sous verrou en cas de collision : contenu identique -> idempotence, divergence -> `store_api.raw_conflict`. Les observations supplémentaires conservent leur provenance complète et ne créent jamais implicitement un canonical absent. La lecture reconstruit `Full` depuis le payload chaud et `Archived` depuis la relation archive ; `Purged` reste un tombstone minimal. La navigation est une keyset stricte `(slot, signature)` ASC/DESC sans `OFFSET`, avec cursor V1 opaque de 109 octets lié au réseau, à la direction, aux bornes et à la dernière clé. Aucun plafond métier de batch n'est introduit : seule la borne physique PostgreSQL de `LIMIT requested + 1` est appliquée.
+
+La rétention physique supportée est `Full -> Archived -> Purged`, sérialisée par `FOR UPDATE`, avec outcomes `Applied`, `AlreadyAtTarget` et `ExpectedStateMismatch`. Le mode normal respecte le tombstone après purge ; `ForceRehydrate` reste explicite et atomique. `Compacted` demeure volontairement non supporté physiquement et retourne `store.postgres_retention_compaction_unsupported` plutôt que de présenter TOAST ou une compression implicite comme contrat KSP. Les erreurs backend sont réduites à des classes/phases statiques puis projetées vers des codes Store/API stables, sans URI, SQL, SQLSTATE, bind ni texte serveur.
+
+La preuve PostgreSQL réelle a conduit à durcir l'introspection de schéma PostgreSQL 17 : canonicalisation ciblée des CHECK numériques reconstruits par le catalogue, conservation des littéraux texte, restauration des helpers de classification de schéma et distinction d'un drift d'une migration déjà enregistrée lorsque `schema_autoupdate=false`. Les ressources SQL V000/V001 et leurs checksums sont restés inchangés pendant ces corrections (`V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450`, `V001 31488cda2f08f3f46c4cdbdbb6c18c243662fada02eac4487040c8735d72cc51`).
+
+Le gate technique final `pre.011` passe audits Rust/Markdown, `cargo check --workspace`, Clippy all-targets, les tests ciblés Store/API/PostgreSQL/Config, les tests et checks façade avec `--no-default-features`, `cargo test --workspace` et les graphes Cargo. Le live `postgres_raw_transaction_live` est ensuite rejoué avec succès sur **PostgreSQL 17**, couvrant bootstrap/drift-repair, atomicité, concurrence identique/divergente, rollback sur collision et annulation, pagination/cursor, rétention/races, ForceRehydrate et réouverture durable. Aucun build Tauri supplémentaire n'est requis : `0.3.3` ne change ni resources applicatives ni packaging desktop. `RawAccountState` PostgreSQL et la complétude RAW restent réservés à `0.3.4`. `prompts/023-V0_3_4_START_PROMPT.md` ouvre cette slice suivante sur les quatre capabilities `RawAccount*`, une migration additive au-dessus de V000/V001, puis la conformance finale des dix capabilities RAW ; l'archive historique kbot3 y reste une source de comparaison ciblée account/observation, jamais une architecture à recopier.
+
 ## 0.3.2 — Store/PostgreSQL runtime foundation — 2026-08-30

 `0.3.2` introduit ensemble `ksp-store-lib` et `ksp-store-postgres-lib` comme fondation runtime/backend PostgreSQL au-dessus des contrats backend-agnostic de `ksp-store-api`, sans encore implémenter de capability RAW métier. La façade `Store` conserve un backend connu `Postgres` activé par défaut via Cargo feature, reste compilable avec `--no-default-features`, lie chaque instance à exactement un `RawNetworkId` et n'expose aucun `Pool`, `Client`, `Row`, `Statement`, driver ou SQL physique. `ksp-config-lib` possède désormais `std.store` avec trois targets nommés `devnet`, `mainnet` et `testnet`, chacun associé à un réseau explicite et à une URI PostgreSQL Secret indépendante ; Store/backend ne lisent directement ni `.env`, ni `KSP_*`, ni `PG*`, ni `.pgpass`.

 - [ ] `0.3.6` — Introduire `ksp-job-api` et un premier job de backfill historique concret consommant `ksp-store-lib`, avec policy/batch-size/progression possédés par le job et non par Store.

 - [X] lifecycle RAW logique — `RawRetentionState`, tombstone minimal, normal-skip et force-rehydrate sont stabilisés en `0.3.1` pour `RawTransaction`.

+`Store::close(self)` consomme l'instance. Une fermeture explicite ne peut donc pas être suivie d'une nouvelle opération via la même valeur.

-## 4. Construire les settings depuis Config
+## 5. Lire une transaction RAW

-Le chemin applicatif recommandé utilise `ksp-config-lib`, propriétaire du document `std.store`, de `.env` et des secrets.
-
-Après construction du `ConfigDocumentEngine` :
+Importer le trait correspondant suffit pour utiliser la façade :

 ```rust
-fn resolve_store_settings(
-    engine: &ksp_config_lib::ConfigDocumentEngine,
-    environment: &ksp_config_lib::ConfigEnvironment,
-    target: std::option::Option<&str>,
-) -> ksp_core_lib::Result<ksp_store_lib::StoreSettings> {
-    let resolved = engine.load_resolved_store_config(target, environment);
-    let resolved = match resolved {
+use ksp_store_lib::RawTransactionRead;
+
+async fn read_transaction(
+    store: &ksp_store_lib::Store,
+    reference: &ksp_store_lib::RawTransactionReference,
+) -> ksp_store_lib::Result<std::option::Option<ksp_store_lib::RawTransaction>> {
+    return store.get_raw_transaction(reference).await;
+}
+```
+
+Une transaction absente retourne `None`. Une transaction `Purged` retourne également `None` pour le payload canonique ; son tombstone reste accessible via la capability de rétention.
+
+## 6. Paginer les références de transactions
+
+La pagination est keyset et utilise un cursor opaque. Le consumer ne doit pas interpréter ses bytes.
+
+```rust
+use ksp_store_lib::RawTransactionRead;
+
+async fn first_transaction_page(
+    store: &ksp_store_lib::Store,
+    network: ksp_store_lib::RawNetworkId,
+) -> ksp_store_lib::Result<ksp_store_lib::RawPage<ksp_store_lib::RawTransactionReference>> {
+    let limit = ksp_store_lib::RawPageLimit::new(100);
+    let limit = match limit {
        std::result::Result::Ok(value) => value,
        std::result::Result::Err(error) => return std::result::Result::Err(error),
    };

-    return std::result::Result::Ok(resolved.into_settings());
+    let slots = ksp_store_lib::RawSlotRange::new(std::option::Option::None, std::option::Option::None);
+    let slots = match slots {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+
+    let query = ksp_store_lib::RawTransactionQuery::new(
+        network,
+        slots,
+        ksp_store_lib::RawSortDirection::Ascending,
+        ksp_store_lib::RawPageRequest::first(limit),
+    );
+
+    return store.list_raw_transactions(&query).await;
 }
 ```

-Targets committed :
+Pour continuer, recopier le cursor retourné par `RawPage::next_cursor()` dans `RawPageRequest::after`. Le réseau, la direction et les bornes de slots doivent rester identiques à ceux de la query ayant produit le cursor.

-```text
-devnet   -> RawNetworkId("devnet")
-mainnet  -> RawNetworkId("mainnet-beta")
-testnet  -> RawNetworkId("testnet")
+## 7. Persister une acquisition canonique
+
+La transaction canonique et son observation initiale forment une seule opération atomique.
+
+```rust
+use ksp_store_lib::RawTransactionWrite;
+
+async fn persist_acquisition(
+    store: &ksp_store_lib::Store,
+    transaction: ksp_store_lib::RawTransaction,
+    observation: ksp_store_lib::RawTransactionObservation,
+) -> ksp_store_lib::Result<ksp_store_lib::RawAcquisitionWriteOutcome> {
+    return store
+        .persist_raw_transaction_acquisition(
+            transaction,
+            observation,
+            ksp_store_lib::RawTransactionAcquisitionMode::Normal,
+        )
+        .await;
+}
 ```

-Chaque target peut utiliser une URI PostgreSQL distincte. `default_profile` sélectionne un seul target ; `Store` ne route pas automatiquement entre plusieurs targets.
+Le mode `Normal` respecte un tombstone `Purged`. `ForceRehydrate` doit être choisi explicitement lorsqu'un caller veut restaurer un payload purgé et que l'identité retenue est compatible.

-## 5. Settings disponibles
+Un contenu divergent sous la même identité produit `ERROR_CODE_RAW_CONFLICT`; Store ne remplace jamais silencieusement le contenu gagnant.

-### `PostgresPoolSettings`
+## 8. Lire et ajouter une observation

-Valeurs par défaut :
+Une observation supplémentaire référence une transaction canonique déjà durable.

-```text
-max_connections         8
-connect_timeout         10 s
-wait_timeout             5 s
-create_timeout          10 s
-recycle_timeout          5 s
+```rust
+use ksp_store_lib::RawTransactionObservationRead;
+use ksp_store_lib::RawTransactionObservationWrite;
+
+async fn use_observation(
+    store: &ksp_store_lib::Store,
+    key: &ksp_store_lib::RawObservationKey,
+    observation: ksp_store_lib::RawTransactionObservation,
+) -> ksp_store_lib::Result<ksp_store_lib::RawObservationWriteOutcome> {
+    let existing = store.get_raw_transaction_observation(key).await;
+    if let std::result::Result::Err(error) = existing {
+        return std::result::Result::Err(error);
+    }
+
+    return store.record_raw_transaction_observation(observation).await;
+}
 ```

-Les getters sont :
+`record_raw_transaction_observation` ne crée pas implicitement le canonique. Une référence absente est signalée par `ERROR_CODE_RAW_REFERENCE_NOT_FOUND`.

-```text
-max_connections()
-connect_timeout()
-wait_timeout()
-create_timeout()
-recycle_timeout()
+## 9. Lire la rétention et le tombstone
+
+```rust
+use ksp_store_lib::RawTransactionRetentionRead;
+
+async fn read_retention(
+    store: &ksp_store_lib::Store,
+    reference: &ksp_store_lib::RawTransactionReference,
+) -> ksp_store_lib::Result<std::option::Option<ksp_store_lib::RawRetentionState>> {
+    let tombstone = store.get_raw_transaction_tombstone(reference).await;
+    if let std::result::Result::Err(error) = tombstone {
+        return std::result::Result::Err(error);
+    }
+
+    return store.get_raw_transaction_retention_state(reference).await;
+}
 ```

-`validate()` vérifie les bornes sans I/O.
+Le tombstone minimal est utile uniquement lorsque le payload a été purgé ; il ne remplace pas le modèle canonique lorsqu'un payload est encore disponible.

-### `PostgresBootstrapSettings`
+## 10. Appliquer une transition de rétention

-Valeurs par défaut :
+La policy qui décide qu'une transition est autorisée appartient au caller. Store applique uniquement la transition demandée de manière atomique.

-```text
-auto_migrate            true
-migration_timeout       30 s
-migration_lock_timeout  10 s
+```rust
+use ksp_store_lib::RawTransactionRetentionWrite;
+
+async fn archive_transaction(
+    store: &ksp_store_lib::Store,
+    reference: ksp_store_lib::RawTransactionReference,
+) -> ksp_store_lib::Result<ksp_store_lib::RawRetentionWriteOutcome> {
+    let transition = ksp_store_lib::RawTransactionRetentionTransition::try_new(
+        reference,
+        ksp_store_lib::RawRetentionState::Full,
+        ksp_store_lib::RawRetentionState::Archived,
+    );
+    let transition = match transition {
+        std::result::Result::Ok(value) => value,
+        std::result::Result::Err(error) => return std::result::Result::Err(error),
+    };
+
+    return store.transition_raw_transaction_retention(transition).await;
+}
 ```

-Getters :
+Le backend PostgreSQL supporte physiquement `Full -> Archived -> Purged`. Une transition impliquant `Compacted` est rejetée par ce backend tant qu'aucune représentation compactée réelle n'est implémentée.
+
+## 11. Diagnostics et erreurs
+
+Les snapshots et erreurs de façade n'exposent ni URI, host, user, database, SQL, handle backend, valeur de bind ni texte d'erreur PostgreSQL.
+
+Les codes Store utiles incluent notamment :

 ```text
-auto_migrate()
-migration_timeout()
-migration_lock_timeout()
+store.wrong_network
+store.raw_reference_not_found
+store.postgres_read_failed
+store.postgres_write_failed
+store.postgres_data_invalid
+store.postgres_page_limit_unsupported
+store.postgres_retention_compaction_unsupported
 ```

-### `StoreSettings`
+Les conflits et queries invalides utilisent les codes backend-neutral `store_api.raw_conflict` et `store_api.raw_query_invalid`.

-La surface expose :
+## 12. Limites de la façade

-```text
-backend()
-backend_kind()
-network()
-shutdown_timeout()
-validate()
-```
+La façade ne fournit pas d'accès public au SQL, au pool, aux clients ou transactions PostgreSQL. Les capabilities `RawAccount*` réexportées par l'API commune ne sont pas encore dispatchées par `Store`.

-`StoreSettings::new` permet de choisir explicitement le timeout de shutdown. `StoreSettings::with_default_shutdown` utilise la borne commune par défaut de 5 secondes.
-
-## 6. Health et diagnostics
-
-`StoreRuntimeSnapshot` est synchrone et ne déclenche aucune I/O. Il expose uniquement :
-
-```text
-backend_kind
-network
-pool_capacity
-pool_size
-pool_available
-pool_waiting
-```
-
-`StoreHealthSnapshot` ajoute une probe async bornée :
-
-```text
-state = Ready | NotReady
-migration_version
-pending_migration_count
-last_error_code
-runtime snapshot
-```
-
-Aucun snapshot n'expose URI, host, user, database, SQL, handle backend ou texte d'erreur PostgreSQL.
-
-## 7. Limite fonctionnelle actuelle
-
-`ksp-store-lib` réexporte les modèles et traits RAW de `ksp-store-api`, mais le backend PostgreSQL de la fondation n'implémente encore aucune capability `RawTransaction*` ou `RawAccount*`.
-
-Les consumers ne doivent donc pas interpréter la disponibilité du runtime PostgreSQL comme une persistence métier déjà présente.
+La taille de page est une primitive de navigation. Les décisions de batch, priorité, backlog et scheduling appartiennent aux workers/jobs, pas à Store.

+L'acquisition canonique et son observation initiale sont commises dans une seule transaction PostgreSQL.

+
+`list_raw_transactions` parcourt les références canoniques récupérables avec un ordre total `(slot, signature)`. Les tombstones `Purged` sont exclus.
+
+La continuation est une keyset stricte, jamais un `OFFSET`. Le cursor backend V1 est opaque et lié au réseau, à la direction et aux bornes de slots de la query. Store n'impose aucun plafond métier arbitraire à la taille de page ; seule la limitation physique du `LIMIT + 1` PostgreSQL est exposée.

+## Rétention RAW transaction

+`transition_raw_transaction_retention` applique les transitions physiques :

+
+Le backend verrouille la ligne canonique avec `FOR UPDATE`, compare l'état courant à l'état attendu et applique la mutation atomiquement. L'archivage conserve le payload exact dans la relation archive ; la purge conserve seulement le tombstone minimal.

-```
-
-Le bootstrap maintient :
-
-```text

-
-`auto_migrate = false` permet de vérifier l'état sans appliquer de migration pending.
-
-## 6. Classifier les erreurs sans fuite
+Les méthodes backend retournent uniquement des modèles `ksp-store-api`.

 ```rust
+async fn read_transaction_state(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    reference: &ksp_store_api::RawTransactionReference,
+) -> std::result::Result<std::option::Option<ksp_store_api::RawTransaction>, ksp_store_postgres_lib::PostgresBackendError> {
+    let retention = backend.get_raw_transaction_retention_state(reference).await;
+    if let std::result::Result::Err(error) = retention {
+        return std::result::Result::Err(error);
+    }
+
+    let tombstone = backend.get_raw_transaction_tombstone(reference).await;
+    if let std::result::Result::Err(error) = tombstone {
+        return std::result::Result::Err(error);
+    }
+
+    return backend.get_raw_transaction(reference).await;
+}
+```
+
+`Full` lit le payload chaud, `Archived` reconstruit le payload depuis l'archive et `Purged` retourne `None`. Un tombstone purgé reste lisible séparément.
+
+Un réseau différent de celui du backend est rejeté avant acquisition d'un client du pool.
+
+## 6. Lire une observation
+
+```rust
+async fn read_observation(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    key: &ksp_store_api::RawObservationKey,
+) -> std::result::Result<std::option::Option<ksp_store_api::RawTransactionObservation>, ksp_store_postgres_lib::PostgresBackendError> {
+    return backend.get_raw_transaction_observation(key).await;
+}
+```
+
+Les rows PostgreSQL, SQLSTATE, statements et valeurs de bind ne traversent jamais cette API.
+
+## 7. Persister une acquisition canonique
+
+```rust
+async fn persist_acquisition(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    transaction: ksp_store_api::RawTransaction,
+    observation: ksp_store_api::RawTransactionObservation,
+) -> std::result::Result<ksp_store_api::RawAcquisitionWriteOutcome, ksp_store_postgres_lib::PostgresBackendError> {
+    return backend
+        .persist_raw_transaction_acquisition(
+            transaction,
+            observation,
+            ksp_store_api::RawTransactionAcquisitionMode::Normal,
+        )
+        .await;
+}
+```
+
+L'opération est atomique : le canonique et son observation initiale sont tous deux durables ou aucun ne l'est. Une identité déjà présente avec un contenu identique est idempotente ; un contenu divergent retourne `PostgresBackendErrorKind::Conflict` sans overwrite silencieux.
+
+Pour un tombstone purgé compatible, le mode `Normal` ne restaure pas le payload. `ForceRehydrate` doit être demandé explicitement pour rétablir un payload `Full`.
+
+## 8. Ajouter une observation à un canonique existant
+
+```rust
+async fn record_observation(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    observation: ksp_store_api::RawTransactionObservation,
+) -> std::result::Result<ksp_store_api::RawObservationWriteOutcome, ksp_store_postgres_lib::PostgresBackendError> {
+    return backend.record_raw_transaction_observation(observation).await;
+}
+```
+
+Cette opération ne crée jamais la transaction canonique. Une référence absente retourne `ReferenceNotFound`; une transaction purgée produit l'outcome `NotRecorded` prévu par l'API.
+
+## 9. Paginer les transactions
+
+```rust
+async fn list_transactions(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    query: &ksp_store_api::RawTransactionQuery,
+) -> std::result::Result<ksp_store_api::RawPage<ksp_store_api::RawTransactionReference>, ksp_store_postgres_lib::PostgresBackendError> {
+    return backend.list_raw_transactions(query).await;
+}
+```
+
+La navigation est keyset sur `(slot, signature)` et exclut les tombstones `Purged`. Le cursor retourné est opaque et lié au réseau, à la direction et aux bornes de slots de la query qui l'a produit.
+
+Le backend n'utilise pas `OFFSET` et n'impose pas de plafond métier arbitraire. La seule borne exposée ici provient de la représentation physique de `LIMIT + 1` dans PostgreSQL.
+
+## 10. Appliquer une transition de rétention
+
+```rust
+async fn apply_retention(
+    backend: &ksp_store_postgres_lib::PostgresBackend,
+    transition: ksp_store_api::RawTransactionRetentionTransition,
+) -> std::result::Result<ksp_store_api::RawRetentionWriteOutcome, ksp_store_postgres_lib::PostgresBackendError> {
+    return backend.transition_raw_transaction_retention(transition).await;
+}
+```
+
+Le backend applique la transition choisie par le caller ; il ne décide pas de la policy d'éligibilité. Les transitions physiques prises en charge sont `Full -> Archived` puis `Archived -> Purged`.
+
+Une transition impliquant `Compacted` est refusée avec `PostgresBackendErrorKind::RetentionCompactionUnsupported` tant qu'aucune représentation compactée réelle n'est disponible.
+
+## 11. Classifier les erreurs sans fuite
+
+```rust
+fn classify(error: &ksp_store_postgres_lib::PostgresBackendError) {
    match error.kind() {
        ksp_store_postgres_lib::PostgresBackendErrorKind::ConfigInvalid => {}
        ksp_store_postgres_lib::PostgresBackendErrorKind::ConnectFailed => {}

    }

    let _safe_phase = error.phase();
+}
 ```

-Ne pas reconstruire un diagnostic utilisateur à partir de l'erreur brute PostgreSQL : cette erreur n'est volontairement pas conservée par le bridge.
+`PostgresBackendError` conserve uniquement une classification KSP et une phase statique. Ne pas reconstruire de diagnostic utilisateur à partir d'une erreur brute PostgreSQL.

-## 7. Ce que cette crate ne permet pas encore
+## 12. Limites du backend direct

-La fondation physique n'implémente pas les traits `RawTransaction*` ou `RawAccount*` de `ksp-store-api`.
+Le backend ne lit aucune variable d'environnement et ne possède aucune sélection de target Config. Les applications, jobs et workers doivent normalement passer par `ksp-store-lib`.

-Un backend ouvert et healthy prouve uniquement :
-
-```text
-connexion/pool
-TLS selon policy
-bootstrap/history
-health/readiness
-close borné
-```
-
-Il ne prouve aucune persistence métier RAW.
+Les capabilities `RawAccount*` ne sont pas implémentées par ce backend. Les décisions de batch, priorité, backlog, scheduling et policy de rétention restent hors de sa responsabilité.

+# Delta `0.3.3-pre.001` — audit et physical design RawTransaction PostgreSQL
+
+## 1. Objet
+
+Ouverture de :
+
+```text
+0.3.3 — Store/PostgreSQL RawTransaction vertical slice
+```
+
+Cette tranche reste volontairement documentaire/conception : elle fixe l'audit, le threat model, le design physique V001 et le séquencement avant toute migration ou persistence métier.
+
+## 2. Base
+
+Base canonique :
+
+```text
+v0.3.2
+```
+
+Le gate opérateur fourni pour `0.3.2` est propre : audits Rust/Markdown, workspace check, Clippy, tests Store/API/PostgreSQL foundation/Config et `ksp-store-lib --no-default-features` passent ; les tests live restent opt-in/ignored conformément à la fondation.
+
+## 3. Version
+
+Version workspace après overlay :
+
+```text
+0.3.3-pre.1
+```
+
+Label de livraison :
+
+```text
+0.3.3-pre.001
+```
+
+## 4. Fichiers ajoutés
+
+```text
+docs/plans/024-V0_3_3_STORE_POSTGRES_RAW_TRANSACTION_PLAN.md
+docs/validation/020-V0_3_3_STORE_POSTGRES_RAW_TRANSACTION.md
+deltas/0.3.3/pre.001.md
+```
+
+## 5. Fichier modifié
+
+```text
+Cargo.toml
+```
+
+Modifications :
+
+```text
+workspace.package.version : 0.3.2 -> 0.3.3-pre.1
+file header version        : 347 -> 348
+```
+
+## 6. Fichiers supprimés
+
+Aucun.
+
+## 7. Audit effectué
+
+Ont été relus avant design :
+
+- règles générales/KSP/Rust/dépendances/docs/file contracts/version workflow/prompt structure ;
+- architectures Layers/Dependencies/Store/API/Config concernées ;
+- plan/validation `0.3.1` ;
+- source/tests complets `ksp-store-api` ;
+- plan/validation `0.3.2` ;
+- source/tests complets `ksp-store-lib` et `ksp-store-postgres-lib` ;
+- surface Config `std.store` ;
+- archive historique kbot3 ciblée demandée par le prompt ;
+- documentation PostgreSQL/tokio-postgres nécessaire aux choix numériques et de concurrence.
+
+## 8. Décisions majeures
+
+### 8.1 `slot: u64`
+
+`BIGINT` est rejeté pour `slot` car il narrowe le domaine API. V001 utilisera :
+
+```text
+NUMERIC(20,0)
+```
+
+avec conversion décimale fallible et tests jusqu'à `u64::MAX`.
+
+### 8.2 Réseau physique
+
+V001 introduira :
+
+```text
+ksp_store_identity
+```
+
+Une base V001 est mono-réseau. Le binding est créé/validé sous le bootstrap lock afin qu'une URI pointant vers un autre réseau échoue avant exposition d'un backend prêt.
+
+### 8.3 Schéma RAW minimal
+
+Tables décidées :
+
+```text
+ksp_store_identity
+ksp_raw_transactions
+ksp_raw_transaction_observations
+ksp_raw_transaction_archive_payloads
+```
+
+Index métier additionnel unique :
+
+```text
+(slot, signature) WHERE retention_state <> 'purged'
+```
+
+Aucun index provider/status/created_at/hash n'est ajouté sans requête correspondante.
+
+### 8.4 Atomicité/idempotence
+
+Le repository n'utilisera aucun `has_*` préalable. La stratégie est :
+
+```text
+INSERT ... ON CONFLICT DO NOTHING RETURNING
+-> si conflit : SELECT ... FOR UPDATE
+-> comparaison exacte du contenu
+-> AlreadyPresent ou ERROR_CODE_RAW_CONFLICT
+```
+
+Le canonique et son observation d'acquisition sont dans la même transaction PostgreSQL.
+
+### 8.5 Pagination
+
+Ordre total :
+
+```text
+(slot, signature)
+```
+
+Cursor backend-private V1 fixe 109 octets, lié par SHA-256 au réseau, à la direction, au slot range et à la dernière clé. Aucun cap métier arbitraire n'est ajouté.
+
+### 8.6 Rétention
+
+`Full`, `Archived` et `Purged` sont représentables honnêtement par le backend `0.3.3` avec une relation archive séparée du hot path.
+
+`Compacted` n'est pas assimilé au TOAST PostgreSQL et n'est pas simulé. Le plan `0.3.1` le qualifiait déjà d'optionnel ; aucun changement `ksp-store-api` n'est donc justifié. Les transitions qui l'impliquent seront rejetées avant I/O par `store.postgres_retention_compaction_unsupported`.
+
+## 9. Audit kbot3
+
+Classification effectuée :
+
+- **REPRENDRE** : unicités, FK, keyset/index slot conceptuels ;
+- **REDESSINER** : fixed bytes, payload opaque, u64 exact, atomicité, conflit réel, réseau, retention compare-and-transition ;
+- **REPORTER** : indexes provider/status/time, processing/replay, batches, apps, AccountState ;
+- **REJETER** : sqlx, `has_*`, JSONB canonique, narrowing i64/i32, FK `SET NULL`, error text SQL, caps 500/1000, processing_state RAW.
+
+Aucun code historique n'est copié.
+
+## 10. Threat model couvert
+
+Le plan couvre explicitement :
+
+- mauvaise URI/réseau ;
+- DB bytes malformés ;
+- overflow u64 ;
+- observation orpheline ;
+- inserts identiques/divergents concurrents ;
+- collision observation ;
+- cursor hostile/replay ;
+- ambiguïté pagination ;
+- retention race ;
+- purge/read/write race ;
+- ForceRehydrate race ;
+- fuite SQL/server text ;
+- cancellation/rollback ;
+- migration mismatch.
+
+## 11. Séquencement recalibré
+
+Le forecast initial est étendu à `pre.013` afin de séparer proprement :
+
+1. généralisation du moteur de migration ;
+2. V001/binding réseau ;
+3. mapping/read ;
+4. write/observation atomiques ;
+5. pagination ;
+6. rétention ;
+7. façade ;
+8. live PostgreSQL ;
+9. hardening ;
+10. gate ;
+11. docs ;
+12. publication.
+
+## 12. Hors scope conservé
+
+Aucun changement fonctionnel n'est apporté à :
+
+```text
+RawAccountState
+N2
+workers/jobs/backfills
+apps
+transport
+codecs wire
+event bus
+compression/archive worker global
+autres backends
+```
+
+## 13. Validations exécutées
+
+Audit statique de la base et de l'overlay :
+
+```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/0.3.3
+  Markdown table audit: clean (214 table(s), 131 file(s))
+
+assertions structurelles locales
+  workspace.package.version = 0.3.3-pre.1
+  headers/version des trois nouveaux Markdown corrects
+  aucune référence résiduelle au faux code API RAW_RETENTION_UNSUPPORTED
+```
+
+L'audit de base couvre aussi manifests/features, modules/exports, V000 et checksum, Config `std.store`, plans/validations `0.3.1`/`0.3.2`, tests hardening/completeness et preuve live documentée.
+
+## 14. Validations non exécutées
+
+Le conteneur d'assemblage ne fournit pas l'exécutable `cargo`. Les commandes suivantes sont donc **NON EXÉCUTÉES**, jamais déclarées PASS :
+
+```text
+cargo fmt --all
+cargo check --workspace
+cargo clippy --workspace --all-targets
+cargo test -p ksp-store-api
+cargo test -p ksp-store-lib
+cargo test -p ksp-store-postgres-lib
+cargo test -p ksp-config-lib
+cargo check -p ksp-store-lib --no-default-features
+```
+
+Les tests PostgreSQL live ne sont pas exécutés non plus. `pre.001` ne modifie aucun SQL/runtime métier, la preuve foundation réelle `0.3.2` est déjà acquise et le futur test RawTransaction n'existe pas encore.
+
+## 15. Questions ouvertes
+
+Aucune question de design bloquante n'est laissée ouverte par `pre.001`.
+
+Les valeurs runtime retenues sont déjà fixées :
+
+```text
+store.postgres_retention_compaction_unsupported
+store.wrong_network
+store.raw_reference_not_found
+store.postgres_read_failed
+store.postgres_write_failed
+store.postgres_data_invalid
+store.postgres_page_limit_unsupported
+```
+
+Le checksum V001 n'est pas une question de design : il sera calculé sur les bytes exacts lorsque `V001__raw_transaction.sql` sera créé en `pre.003`.
+
+## 16. Gate demandé
+
+```bash
+cargo fmt --all
+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/0.3.3

+cargo test -p ksp-store-postgres-lib
+cargo test -p ksp-config-lib
+cargo check -p ksp-store-lib --no-default-features
+```
+
+Aucun test PostgreSQL live n'est requis dans cette tranche documentaire.

+# Delta `0.3.3-pre.002` — moteur de migrations PostgreSQL multi-version
+
+## 1. Base requise
+
+```text
+0.3.3-pre.001
+```
+
+Le gate opérateur fourni pour `pre.001` est entièrement vert :
+
+```text
+cargo fmt --all                                         PASS
+audit Rust général / exports / workspace                PASS

+cargo check -p ksp-store-lib --no-default-features       PASS
+```
+
+Les tests live `#[ignore]` restent volontairement hors de ce gate ; `pre.001` était documentaire et `pre.002` ne crée encore aucun SQL métier V001.
+
+## 2. Objectif
+
+Généraliser le bootstrap PostgreSQL V000 acquis en `0.3.2` vers un moteur embedded multi-version avant d'introduire la première migration métier.
+
+La tranche doit préserver :
+
+```text
+checksum immuable
+mismatch terminal
+schema newer terminal
+aucun down automatique
+advisory transaction lock
+migration timeout
+statement timeout
+transaction unique
+metadata shape validation
+erreurs externes non rendues
+```
+
+Elle prépare également la frontière transactionnelle du futur binding `RawNetworkId`, sans créer V001 ni `ksp_store_identity`.
+
+## 3. Version
+
+Le workspace passe à :
+
+```text
+0.3.3-pre.2
+```
+
+## 4. Registre embedded
+
+Le moteur ne possède plus une série de constantes spécialisées V000. Il utilise désormais :
+
+```text
+EMBEDDED_MIGRATIONS: &[EmbeddedMigration]
+```
+
+Le registre réel de cette tranche contient exactement :
+
+```text
+V000 bootstrap
+```
+
+Aucune V001 n'est anticipée dans les migrations physiques.
+
+Chaque entrée possède :
+
+```text
+version
+name
+sql embedded
+migration hook
+```
+
+Le registre est validé avant I/O :
+
+```text
+non vide
+commence à 0
+versions contiguës strictement ordonnées
+name non vide
+SQL non vide
+```
+
+La version courante est dérivée du dernier élément du registre.
+
+## 5. Validation d'historique multi-version
+
+L'historique PostgreSQL est maintenant validé comme **préfixe exact** du registre embedded.
+
+Cas :
+
+```text
+historique exact complet        -> prêt
+préfixe exact                   -> migrations pending
+nom divergent                   -> MigrationMismatch
+checksum divergent              -> MigrationMismatch
+version/trou inattendu connu     -> MigrationMismatch
+version > runtime courant        -> SchemaNewer
+metadata existante sans V000     -> MigrationMismatch
+```
+
+Un préfixe exact n'est donc plus confondu avec une divergence : il représente précisément le cas normal d'upgrade V000 -> V001 attendu en `pre.003`.
+
+## 6. Application des migrations pending
+
+Sous la transaction PostgreSQL et l'advisory lock déjà acquis :
+
+```text
+load/validate history
+-> déterminer next_index
+-> refuser si pending && auto_migrate=false
+-> appliquer chaque migration dans l'ordre
+-> vérifier metadata shape
+-> exécuter migration hook
+-> insérer checksum/name/version dans history
+-> migration suivante
+-> commit unique
+```
+
+Une erreur à n'importe quelle étape provoque le rollback transactionnel normal ; aucune migration partiellement enregistrée n'est considérée appliquée.
+
+## 7. Hook atomique de binding réseau
+
+`bootstrap` reçoit désormais le `RawNetworkId` du backend et le transmet jusqu'à chaque migration.
+
+Le moteur distingue deux contextes privés :
+
+```text
+Existing   migration déjà présente dans history à la réouverture
+AppliedNow migration exécutée pendant le bootstrap courant
+```
+
+Pour les migrations déjà appliquées, le hook est rejoué sous la transaction/advisory lock avant que le backend puisse être déclaré prêt. Pour une migration nouvellement appliquée, l'ordre est :
+
+```text
+batch_execute(migration.sql)
+-> metadata shape check
+-> migration hook AppliedNow
+-> INSERT history
+-> commit final
+```
+
+V000 utilise :
+
+```text
+MigrationHook::None
+```
+
+`pre.003` pourra donc ajouter le hook V001 `ksp_store_identity` avec deux comportements sûrs : création/validation en `AppliedNow`, validation stricte sans recréation en `Existing`. La frontière reste transactionnelle et ne crée aucune seconde phase de bootstrap race-prone.
+
+Aucune identité réseau n'est écrite dans cette tranche.
+
+## 8. Compatibilité V000
+
+Le fichier reste inchangé :
+
+```text
+crates/ksp-store-postgres-lib/migrations/V000__bootstrap.sql
+```
+
+Checksum conservé :
+
+```text
+d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450
+```
+
+La metadata historique reste :
+
+```text
+ksp_store_schema_migrations
+version BIGINT PRIMARY KEY
+name TEXT NOT NULL
+checksum TEXT NOT NULL
+applied_at TIMESTAMPTZ NOT NULL
+```
+
+## 9. Tests du moteur
+
+Les unit tests `migration.rs` couvrent maintenant :
+
+```text
+registre réel V000 immutable
+checksum V000 stable
+current version dérivée du registre
+registre synthétique V000/V001 ordonné
+historique V000 comme préfixe pending valide
+historique synthétique V000/V001 complet
+registre vide/non-zero/gap/name vide/SQL vide rejeté
+nom/checksum/history missing/gap rejetés
+version future -> SchemaNewer
+```
+
+Un canari d'intégration source vérifie aussi :
+
+```text
+registre embedded présent
+hook de migration + contextes `AppliedNow`/`Existing` présents
+RawNetworkId transmis au hook
+validation préfixe utilisée
+application pending utilisée
+aucun V001__raw_transaction.sql
+aucun ksp_store_identity
+```

+
+Aucun test PostgreSQL live n'est requis : le SQL physique reste strictement V000 et aucun schéma métier n'est introduit.
+
+## 16. Suite
+
+Après gate vert, `0.3.3-pre.003` créera la vraie migration V001, les tables/constraints/indexes décidés en `pre.001` et le binding atomique `ksp_store_identity` via le hook préparé ici.

+
+## 1. Base et objectif
+
+Ce correctif s'applique **par-dessus le commit `0.3.3-pre.003` déjà réalisé**. Il ne réécrit ni ne remplace ce commit dans l'historique.
+
+Le gate opérateur de `pre.002` est vert. Le gate opérateur de `pre.003` n'a pas été fourni avant l'ouverture de ce fix ; aucune commande Cargo du fix n'est donc déclarée PASS dans ce document.
+
+Objectif du fix : conserver les bonnes garanties fonctionnelles historiques d'inspection/réconciliation du schéma PostgreSQL sans reprendre l'architecture kbot3, et corriger V001 avant l'ouverture du repository `RawTransaction` de `pre.004`.
+
+Version workspace après application :
+
+```text
+0.3.3-pre.3.fix.1
+```
+
+Identifiant de livraison :
+
+```text
+0.3.3-pre.003-fix.001
+```
+
+## 2. Décisions corrigées
+
+### 2.1 Migration logique vs ressources physiques
+
+V000 et V001 restent des **migrations logiques** versionnées. Les objets physiques ne deviennent pas chacun une version de migration.
+
+Arborescence retenue :
+
+```text
+crates/ksp-store-postgres-lib/migrations/
+  v000_bootstrap/
+    tables/
+      001_ksp_store_schema_migrations.sql
+  v001_raw_transaction/
+    tables/
+      001_ksp_store_identity.sql
+      002_ksp_raw_transactions.sql
+      003_ksp_raw_transaction_observations.sql
+      004_ksp_raw_transaction_archive_payloads.sql
+    constraints/
+      001_...sql -> 035_...sql
+    indexes/
+      001_ix_ksp_raw_transactions_slot_signature.sql
+```
+
+V001 contient exactement :
+
+```text
+4 tables
+35 contraintes
+1 index
+40 ressources embedded
+```
+
+V000 est seulement déplacée : ses bytes restent strictement identiques.
+
+### 2.2 Checksums
+
+V000 historique :
+
+```text
+d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450
+```
+
+V001 multi-ressources :
+
+```text
+31488cda2f08f3f46c4cdbdbb6c18c243662fada02eac4487040c8735d72cc51
+```
+
+Le checksum V001 est calculé sur le préfixe de format du registre puis, dans l'ordre embedded, sur l'identifiant relatif et les bytes exacts de chaque ressource. Le checksum monolithique `pre.003` n'est pas réutilisé.
+
+Une base ayant réellement enregistré l'ancien checksum V001 du commit `pre.003` n'est jamais réécrite silencieusement : elle doit être réinitialisée si elle est jetable ou réconciliée manuellement.
+
+### 2.3 `IF NOT EXISTS` n'est pas une preuve de compatibilité
+
+Les ressources utilisent `CREATE ... IF NOT EXISTS`, `ADD COLUMN IF NOT EXISTS` ou des guards catalogue lorsque cela permet une création additive idempotente.
+
+Après et avant mutation, le backend introspecte néanmoins le catalogue PostgreSQL. Chaque ressource est classée :
+
+```text
+Compatible
+Missing
+Incompatible
+```
+
+Un objet préexistant du bon nom mais de mauvaise définition est donc refusé.
+
+### 2.4 Contrat physique vérifié
+
+Le module backend-private `schema` contrôle notamment :
+
+- tables gérées et nature `BASE TABLE` ;
+- colonnes obligatoires, type, nullabilité et absence d'identity/generated sur le contrat KSP ;
+- précision/scale `NUMERIC(20,0)` du slot ;
+- PK, FK et CHECK ;
+- définition canonique des contraintes à partir de leur propre ressource SQL ;
+- index partiel `(slot, signature)` hors `purged` ;
+- RLS ;
+- triggers utilisateur actifs ;
+- rewrite rules ;
+- contraintes/indexes uniques externes susceptibles de modifier la sémantique de write.
+
+Les marqueurs COMMENT ne servent pas de preuve de compatibilité et ne sont pas requis.
+
+### 2.5 Extensions externes compatibles
+
+KSP ne requiert pas une égalité byte-for-byte du schéma complet avec son propre DDL. Les extensions externes qui sont prouvées non bloquantes restent admises.
+
+Le correctif tolère notamment :
+
+- une colonne externe nullable, sans default, identity ni generated expression ;
+- un index externe non unique ;
+- une contrainte attendue physiquement équivalente même si son nom diffère.
+
+Le correctif bloque conservativement les extensions susceptibles de modifier/contraindre les writes KSP lorsqu'il ne peut pas en prouver l'innocuité : mauvais type/nullabilité sur une colonne KSP, colonne externe write-blocking, contrainte non équivalente, unique index autonome, trigger actif, rule ou RLS.
+
+### 2.6 Politiques `schema_autocreate` / `schema_autoupdate`
+
+`std.store` passe en format V2 et sépare :
+
+```text
+schema_autocreate
+schema_autoupdate
+```
+
+`schema_autocreate` autorise l'initialisation ou l'adoption contrôlée d'une base sans metadata KSP.
+
+`schema_autoupdate` autorise les migrations pending et les réparations additives sûres de ressources manquantes sur un schéma KSP existant.
+
+Une incompatibilité exigeant une mutation destructive, ambiguë ou non prouvée sûre reste bloquante même avec `schema_autoupdate=true`; le backend émet uniquement une phase/resource sûre pour permettre l'intervention manuelle.
+
+Le format V1 reste lisible : `auto_migrate` est mappé vers les deux politiques. Les constructeurs Rust historiques restent également disponibles et mappent leur booléen vers les deux politiques.
+
+### 2.7 Identité réseau
+
+Le binding V001 reste sous la même transaction et le même advisory lock.
+
+Une `ksp_store_identity` absente alors que V001 est déjà enregistrée n'est jamais reconstruite automatiquement, même avec `schema_autoupdate=true`, afin d'interdire tout rebind réseau silencieux.

+```
+
+L'environnement de génération ne possède pas `cargo`/`rustfmt`. Les gates Cargo ci-dessous restent donc **NON EXÉCUTÉS** jusqu'au passage opérateur.
+
+## 7. Gate opérateur demandé
+
+Après extraction de l'overlay, suppression explicite des deux fichiers monolithiques puis application du formatage :

+
+Le vrai PostgreSQL live du contrat V001, des dérives et des réparations reste volontairement réservé au gate live prévu plus tard dans `0.3.3`; ce fix ne le présente pas comme PASS.

+# Delta `0.3.3-pre.003-fix.002` — correctif compilation et ownership du contrat PostgreSQL
+
+## 1. Base et objectif
+
+Ce correctif s’applique **par-dessus `0.3.3-pre.003-fix.001`**. Le gate opérateur de `fix.001` a confirmé que les audits Rust/Markdown étaient propres, mais a échoué sur deux défauts localisés :
+
+1. `schema.rs` transmettait un `&str` directement dans deux slices de paramètres `tokio-postgres`, alors que le cast vers `&(dyn ToSql + Sync)` nécessite ici un `&&str` ;
+2. cinq constantes internes du contrat de colonnes commençaient par `KSP_`, namespace que les canaris Config réservent aux variables d’environnement runtime, ce qui provoquait à la fois un refus d’ownership Store et une fausse exigence `.env.example`.
+
+Version workspace après application :
+
+```text
+0.3.3-pre.3.fix.2
+```
+
+Identifiant de livraison :
+
+```text
+0.3.3-pre.003-fix.002
+```
+
+## 2. Correctifs
+
+### 2.1 Paramètres catalogue `tokio-postgres`
+
+Les deux appels concernés deviennent :
+
+```text
+transaction.query(UNEXPECTED_CONSTRAINTS_SQL, &[&table])
+transaction.query(UNIQUE_INDEXES_SQL, &[&table])
+```
+
+Aucune requête SQL ni logique d’introspection n’est modifiée.
+
+### 2.2 Namespace `KSP_` réservé à Config
+
+Les constantes privées suivantes sont renommées sans changer leur contenu :
+
+```text
+KSP_STORE_SCHEMA_MIGRATIONS_COLUMNS          -> STORE_SCHEMA_MIGRATIONS_COLUMNS
+KSP_STORE_IDENTITY_COLUMNS                   -> STORE_IDENTITY_COLUMNS
+KSP_RAW_TRANSACTIONS_COLUMNS                 -> RAW_TRANSACTIONS_COLUMNS
+KSP_RAW_TRANSACTION_OBSERVATIONS_COLUMNS     -> RAW_TRANSACTION_OBSERVATIONS_COLUMNS
+KSP_RAW_TRANSACTION_ARCHIVE_PAYLOADS_COLUMNS -> RAW_TRANSACTION_ARCHIVE_PAYLOADS_COLUMNS
+```
+
+Le test ownership n’est pas assoupli et `.env.example` n’est pas pollué par de faux noms runtime.
+
+## 3. Invariants inchangés
+
+Ce fix ne modifie aucune ressource SQL. L’arborescence V000/V001, l’ordre embedded, le binding réseau et le contrat `Compatible/Missing/Incompatible` restent inchangés.
+
+Checksums attendus inchangés :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450

+# Delta `0.3.3-pre.003-fix.003` — clôture Clippy et relocalisation du canari live V000
+
+## 1. Base et objectif
+
+Ce correctif s’applique **par-dessus `0.3.3-pre.003-fix.002`**. Son gate opérateur confirme que les audits Rust/Markdown, `cargo check` jusqu’au backend et les tests Config/ownership sont désormais propres, mais révèle trois défauts résiduels strictement locaux :
+
+1. une variable `name` décodée mais non utilisée dans l’inventaire des indexes uniques ;
+2. cinq usages de l’opérateur `?` dans `expected_constraint_definition`, interdits par la policy workspace `clippy::question_mark_used = deny` ;
+3. le test opt-in `postgres_foundation_live.rs` référence encore l’ancien fichier monolithique V000 supprimé par `fix.001`.
+
+Un warning Clippy de test (`assert!(false, ...)`) est également supprimé afin de garder le gate sans bruit.

+```

+Identifiant de livraison :
+
+```text

+```
+
+## 2. Correctifs
+
+### 2.1 Introspection catalogue
+
+Le nom d’index décodé mais inutilisé est explicitement marqué `_name`. Le comportement reste inchangé : tout index unique externe non adossé à une contrainte reste incompatible.
+
+### 2.2 Policy Clippy `question_mark_used`
+
+`expected_constraint_definition` conserve exactement sa sémantique `Option<String>`, mais remplace les cinq propagations `?` par des `match` explicites retournant `None` lorsque la ressource SQL ne peut pas être découpée selon le contrat attendu.
+
+### 2.3 Canari unitaire
+
+L’assertion constante `assert!(false, ...)` est remplacée par une assertion sur `resource.is_some()`, puis un `match` non paniquant pour satisfaire simultanément le canari et la policy KSP.
+
+### 2.4 Test PostgreSQL live V000
+
+Le `include_str!` du test opt-in suit maintenant le déplacement effectué dans `fix.001` :
+
+```text
+crates/ksp-store-postgres-lib/migrations/v000_bootstrap/tables/001_ksp_store_schema_migrations.sql
+```
+
+Aucun comportement live supplémentaire n’est ajouté.
+
+### 2.5 Documentation backend
+
+Le README et l’USAGE du backend sont réconciliés avec l’arborescence versionnée introduite par `fix.001`; ils ne présentent plus les anciens fichiers monolithiques supprimés comme artefacts actifs.
+
+## 3. Invariants inchangés
+
+Aucune ressource SQL n’est modifiée. Les checksums restent :
+
+```text

+ksp_raw_transaction_observations
+ksp_raw_transaction_archive_payloads
+```
+
+et l'index secondaire suivant :
+
+```text
+ix_ksp_raw_transactions_slot_signature
+    ON ksp_raw_transactions(slot, signature)
+    WHERE retention_state <> 'purged'
+```
+
+Les clés physiques restent :
+
+```text
+ksp_store_identity(singleton)
+ksp_raw_transactions(signature)
+ksp_raw_transaction_observations(observation_key)
+ksp_raw_transaction_archive_payloads(signature)
+```
+
+Aucun ID SQL auxiliaire n'est ajouté.
+
+## 6. Bornes et contraintes
+
+Les contraintes SQL matérialisent les invariants backend-agnostiques déjà acquis :
+
+```text
+network/code UTF-8 ASCII sûr       1..=128 octets
+signature transaction              64 octets
+observation key                    32 octets
+content/source hash                32 octets
+slot                               NUMERIC(20,0), 0..=u64::MAX
+format_version                     BIGINT, 1..=u32::MAX
+RawTimestamp                       BIGINT, 0..=253402300799999
+payload canonical/archive          1..=16 MiB lorsqu'il existe
+source payload size                0..=64 MiB
+origin                             backfill/import/live/repair/replay
+retention physique                 full/archived/purged
+```
+
+`slot` n'est jamais réduit en `BIGINT` signé.
+
+La cohérence de rétention physique impose :
+
+```text
+full       -> payload hot présent
+archived   -> payload hot absent
+purged     -> payload hot absent + block_time absent
+```
+
+La relation archive reste séparée du hot path. V001 ne prétend jamais représenter `Compacted`.
+
+## 7. Binding mono-réseau atomique
+
+V001 déclare le hook privé :
+
+```text
+MigrationHook::StoreIdentity
+```
+
+Le comportement est distinct selon le contexte déjà acquis en `pre.002`.
+
+### `AppliedNow`
+
+Sous la même transaction et le même advisory lock :
+
+```text
+batch_execute(V001)
+-> INSERT singleton=1 + network runtime
+-> relire exactement l'identité
+-> valider singleton + RawNetworkId + égalité réseau
+-> INSERT history V001
+-> commit final
+```
+
+L'insertion n'utilise aucun upsert : une divergence physique ne peut pas être absorbée silencieusement.
+
+### `Existing`
+
+Une réouverture V001 effectue uniquement :
+
+```text
+SELECT singleton, network
+-> exactement une ligne
+-> singleton = 1
+-> network valide RawNetworkId
+-> network == backend.network
+```
+
+Une identité absente, multiple, illisible, malformée ou différente devient `MigrationMismatch` avec une phase statique. La valeur réseau persistée et les erreurs PostgreSQL ne sont jamais retenues/rendues.
+
+Une base V001 dont l'identité a disparu n'est donc jamais réclamée/rebindée automatiquement.
+
+## 8. `Compacted` PostgreSQL non supporté
+
+Le code stable suivant est désormais matérialisé par valeur dans le backend et la façade :
+
+```text
+store.postgres_retention_compaction_unsupported
+```
+
+Exports :
+
+```text
+ksp_store_postgres_lib::ERROR_CODE_POSTGRES_RETENTION_COMPACTION_UNSUPPORTED
+ksp_store_lib::ERROR_CODE_POSTGRES_RETENTION_COMPACTION_UNSUPPORTED
+```
+
+Les deux crates construisent le même `ErrorCode` KSP sans créer de dépendance inverse `ksp-store-postgres-lib -> ksp-store-lib`.
+
+L'utilisation opérationnelle de ce code par `RawTransactionRetentionWrite` reste réservée à `pre.007`.
+
+## 9. Tests statiques ajoutés/actualisés
+
+Les tests de migration couvrent désormais :
+
+```text
+registre réel [V000,V001]
+V000 checksum immuable
+V001 checksum exact
+version courante = 1
+V000 seul = préfixe valide / V001 pending
+historique complet V000+V001 valide
+mismatch/newer toujours terminaux
+inventaire exact des quatre tables
+index partiel exact
+slot u64 max sans narrowing
+bornes u32/timestamp/payload/source payload
+retention physique sans compacted
+hook StoreIdentity réel
+contextes AppliedNow / Existing
+absence de repository/capability dans la tranche
+```
+
+Les canaris de surface publique sont actualisés :
+
+```text
+ksp-store-postgres-lib root pub use : 7 -> 8
+ksp-store-lib root pub use          : 84 -> 85
+```
+
+La seule nouvelle surface est le code d'erreur PostgreSQL `Compacted` explicitement planifié.
+
+Le test live foundation hérité de `0.3.2` est maintenu cohérent avec V001 sans devenir la preuve métier de cette release :
+
+```text
+version health attendue              0 -> 1
+refus de départ                       toute table Store V000/V001 déjà présente
+cleanup                               ensemble des tables Store V000/V001 possédées
+preuve de rollback historique         V000 inchangée
+statut dans le gate ordinaire         toujours #[ignore]
+```
+
+Il n'est pas exécuté dans cette tranche ; les scénarios V001 spécifiques restent réservés à `pre.009`.
+
+## 10. Preuves volontairement différées
+
+Cette tranche ne prétend pas avoir exécuté PostgreSQL réel pour V001.
+
+Restent au gate live `pre.009` :
+
+```text
+upgrade réel V000 -> V001
+rollback réel si hook échoue
+réouverture même réseau
+réouverture réseau différent
+identity supprimée/malformée sur DB réelle
+checksum V001 divergent sur DB réelle
+concurrence réelle du bootstrap V001
+```
+
+Ces points ne sont donc pas marqués PASS dans la validation `pre.003`.

+# Delta `0.3.3-pre.004` — mapping PostgreSQL privé et lectures RawTransaction
+
+## 1. Base requise
+
+```text
+0.3.3-pre.3.fix.3
+```
+
+Le gate opérateur fourni pour `pre.003-fix.003` est entièrement vert :
+
+```text
+cargo fmt --all                                         PASS
+audit Rust général / exports / workspace                PASS

+cargo check -p ksp-store-lib --no-default-features       PASS
+```
+
+La V001 split, son contrat catalogue et les politiques `schema_autocreate/schema_autoupdate` sont donc considérés acquis.
+
+## 2. Objectif
+
+Implémenter la tranche lecture de la vertical slice PostgreSQL `RawTransaction` sans ouvrir encore les écritures ni la pagination :
+
+```text
+mapping SQL privé
+get_raw_transaction
+get_raw_transaction_observation
+get_raw_transaction_retention_state
+get_raw_transaction_tombstone
+```
+
+Les méthodes du backend retournent uniquement des modèles `ksp-store-api`. Aucun `tokio_postgres::Row`, SQL, SQLSTATE ou bind ne traverse le bridge public.
+
+## 3. Version
+
+Le workspace passe à :
+
+```text
+0.3.3-pre.4
+```
+
+## 4. Module physique privé
+
+Nouveau module :
+
+```text
+crates/ksp-store-postgres-lib/src/raw_transaction.rs
+```
+
+Il possède les SELECT et les codecs physiques de cette tranche. `runtime.rs` ne contient aucun SQL métier et délègue les quatre lectures au module privé.
+
+La tranche reste strictement read-only :
+
+```text
+INSERT INTO   absent
+UPDATE        absent
+DELETE FROM   absent
+```
+
+Les écritures canonique/observation restent `pre.005`; `list_raw_transactions` et le cursor restent `pre.006`.
+
+## 5. Conversion physique exacte
+
+Le mapping respecte les contrats `ksp-store-api` sans narrowing :
+
+```text
+slot NUMERIC(20,0)             -> PostgreSQL ::text -> parse u64
+format_version BIGINT          -> u32::try_from
+block/observed/received BIGINT -> u64::try_from -> RawTimestamp
+source payload size BIGINT           -> u64::try_from + borne API
+signature                      -> BYTEA exactement 64 bytes
+hash/key                       -> BYTEA exactement 32 bytes
+format/provenance codes        -> constructeurs API fallibles
+```
+
+Le chemin `slot` couvre explicitement :
+
+```text
+0
+i64::MAX
+i64::MAX + 1
+u64::MAX
+```
+
+Aucune dépendance décimale supplémentaire n'est introduite.
+
+## 6. `get_raw_transaction`
+
+La requête lit la ligne canonique avec `LEFT JOIN` du payload archive.
+
+Décodage :
+
+```text
+Full
+  payload chaud obligatoire
+  payload archive interdit
+  -> Some(RawTransaction)
+
+Archived
+  payload chaud absent
+  payload archive obligatoire
+  -> Some(RawTransaction)
+
+Purged
+  payload chaud absent
+  payload archive absent
+  block_time absent
+  -> None
+```
+
+Toute incohérence de forme, entier hors domaine, code invalide, signature/hash mal dimensionné ou payload incompatible produit `DataInvalid` sans conserver la valeur hostile.
+
+## 7. Observation
+
+`get_raw_transaction_observation` reconstruit :
+
+```text
+observation_key
+transaction signature
+provider
+protocol
+acquisition_method
+origin
+received_at
+capture_session_id optionnel
+commitment optionnel
+endpoint_id optionnel
+filter_id optionnel
+observed_at optionnel
+source_payload_hash optionnel
+source_payload_size_bytes optionnel
+```
+
+`RawObservationKey` ne porte pas de réseau ; le `RawTransactionReference` reconstruit utilise donc exclusivement le réseau mono-backend déjà vérifié à l'ouverture.
+
+L'ordre temporel `observed_at <= received_at` est revalidé par le constructeur API.
+
+## 8. Rétention et tombstone
+
+`get_raw_transaction_retention_state` mappe uniquement les états physiques supportés par V001 :
+
+```text
+full
+archived
+purged
+```
+
+Une valeur inconnue ou `compacted` stockée physiquement est une corruption `DataInvalid`; `Compacted` n'a toujours aucune représentation PostgreSQL prétendue.
+
+`get_raw_transaction_tombstone` retourne `Some` uniquement pour `Purged`, vérifie également que `block_time` est absent, puis reconstruit exactement :
+
+```text
+network + signature
+slot
+format_id
+format_version
+content_hash
+```
+
+Pour `Full` ou `Archived`, le résultat est `None`.
+
+## 9. Réseau pré-I/O
+
+Les trois lectures portant un `RawTransactionReference` passent par un garde privé commun avant `pool.get()` :
+
+```text
+reference.network == backend.network -> continuer
+sinon                                -> WrongNetwork
+```
+
+Le mauvais réseau ne consomme donc aucune connexion PostgreSQL et ne dépend d'aucun SQL.
+
+## 10. Erreurs backend
+
+`PostgresBackendErrorKind` ajoute :
+
+```text
+DataInvalid
+ReadFailed
+WrongNetwork
+```
+
+Classification :
+
+```text
+pool wait/connect       -> kinds existants PoolTimeout/ConnectFailed
+SELECT/driver read      -> ReadFailed
+row/cardinality/model   -> DataInvalid
+reference mauvais réseau -> WrongNetwork
+```
+
+`PostgresBackendError` reste composé uniquement de :
+
+```text
+kind
+phase &'static str
+```
+
+Aucune erreur externe n'est retenue ni rendue.
+
+## 11. Surface backend
+
+`PostgresBackend` expose désormais :
+
+```text
+get_raw_transaction
+get_raw_transaction_observation
+get_raw_transaction_retention_state
+get_raw_transaction_tombstone
+```
+
+Ces méthodes ne constituent pas encore les implémentations finales des traits `RawTransaction*` : `RawTransactionRead` exige également `list_raw_transactions`, réservé à `pre.006`. Les six traits seront complets avant leur dispatch par `ksp-store-lib` en `pre.008`.
+
+## 12. Tests déterministes
+
+Le nouveau miroir `unit_tests/raw_transaction.rs` couvre notamment :
+
+```text
+Full u64::MAX
+Archived u64::MAX
+Purged -> None
+résidu payload/block_time sur Purged -> DataInvalid
+provenance complète/optionnelle
+source payload max
+slot > u64::MAX -> DataInvalid
+hash mal dimensionné -> DataInvalid
+origin hostile -> DataInvalid sans écho
+états Full/Archived/Purged
+Compacted physique -> DataInvalid
+tombstone u64::MAX/u32::MAX
+wrong-network pré-I/O
+```
+
+Les canaris d'intégration figent également :
+
+```text
+module SQL privé
+aucun write SQL en pre.004
+aucune dépendance nouvelle
+surface publique sans types PostgreSQL
+nouveaux error kinds sûrs
+```
+
+## 13. Migrations
+
+Aucune ressource de migration n'est modifiée.
+
+Les checksums restent :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450

+cargo check -p ksp-store-lib --no-default-features       PASS
+```
+
+Les lectures physiques `RawTransaction` de `pre.004` sont donc acquises.
+
+## 2. Objectif
+
+Implémenter la tranche écriture de la vertical slice PostgreSQL sans ouvrir encore pagination ni transitions mutantes de rétention :
+
+```text
+persist_raw_transaction_acquisition
+record_raw_transaction_observation
+```
+
+La première opération doit rendre le canonical et son observation atomiques. Les deux opérations doivent être réellement idempotentes et ne jamais confondre une collision de clé avec un contenu identique.
+
+## 3. Version
+
+Le workspace passe à :
+
+```text
+0.3.3-pre.5
+```
+
+## 4. Pré-I/O
+
+Avant `pool.get()` :
+
+```text
+transaction.reference.network == backend.network
+observation.transaction.network == backend.network
+observation.transaction == transaction.reference
+```
+
+Un mauvais réseau retourne `WrongNetwork`. Une acquisition composée de deux références logiques différentes retourne `Conflict` sans toucher PostgreSQL.
+
+`record_raw_transaction_observation` valide également son réseau avant toute acquisition du pool.
+
+## 5. Acquisition atomique canonique + observation
+
+L'algorithme est :
+
+```text
+BEGIN
+  INSERT canonical
+    ON CONFLICT (signature) DO NOTHING
+    RETURNING signature
+
+  si inséré
+    -> candidate Inserted
+
+  sinon
+    SELECT canonical FOR UPDATE
+    SELECT archive payload éventuel
+    comparer le contenu réel
+
+  écrire/idempotenter observation
+
+COMMIT
+```
+
+Toute erreur après l'insert canonique, notamment une collision d'observation divergente, fait sortir sans commit : PostgreSQL rollbacke donc l'ensemble de l'acquisition.
+
+Aucun `has_*` ni SELECT préventif n'est introduit.
+
+## 6. Idempotence canonique
+
+Pour `Full` et `Archived`, l'égalité exige exactement :
+
+```text
+reference
+slot
+block_time
+format_id
+format_version
+content_hash
+payload bytes
+```
+
+Le hash n'est jamais utilisé seul lorsque les octets restent disponibles.
+
+Résultats :
+
+```text
+première insertion                 -> Inserted
+même identité + contenu identique -> AlreadyPresent
+même identité + contenu divergent -> Conflict
+```
+
+Le conflit backend sera projeté vers `ERROR_CODE_RAW_CONFLICT` par la façade dans `pre.008`.
+
+## 7. Tombstone et ForceRehydrate
+
+Lorsqu'une signature existe en `Purged`, le backend exige que la forme physique soit réellement minimale :
+
+```text
+payload hot absent
+payload archive absent
+block_time absent
+```
+
+Il compare ensuite uniquement les métadonnées conservées par le tombstone :
+
+```text
+reference
+slot
+format_id
+format_version
+content_hash
+```
+
+Une divergence produit `Conflict`.
+
+Pour un tombstone compatible :
+
+```text
+Normal
+  -> SkippedPurged / NotRecorded
+
+ForceRehydrate
+  -> UPDATE payload + block_time + state=full
+  -> observation dans la même transaction
+  -> Rehydrated
+```
+
+Le `ForceRehydrate` ne masque donc jamais une divergence détectable.
+
+## 8. Observation idempotente
+
+L'observation utilise :
+
+```text
+INSERT ...
+ON CONFLICT (observation_key) DO NOTHING
+RETURNING observation_key
+```
+
+Après collision :
+
+```text
+SELECT observation ... FOR UPDATE
+```
+
+Puis le modèle reconstruit est comparé intégralement à l'observation entrante : référence transaction + provenance complète.
+
+Résultats :
+
+```text
+key absente + insert réussi       -> Inserted
+key présente + contenu identique  -> AlreadyPresent
+key présente + contenu divergent  -> Conflict
+```
+
+## 9. Observation write séparée
+
+`record_raw_transaction_observation` ne crée jamais un canonical implicite.
+
+Sous transaction :
+
+```text
+SELECT retention_state FROM canonical FOR UPDATE
+```
+
+Puis :
+
+```text
+canonical absent  -> ReferenceNotFound
+canonical Purged  -> NotRecorded
+Full / Archived   -> insertion/idempotence observation
+```
+
+Le verrou canonical prépare aussi la sérialisation future avec purge/rehydrate de `pre.007`.
+
+## 10. Erreurs backend
+
+`PostgresBackendErrorKind` ajoute :
+
+```text
+Conflict
+ReferenceNotFound
+WriteFailed
+```
+
+Ces erreurs restent composées exclusivement de :
+
+```text
+kind
+phase &'static str
+```
+
+Aucun texte PostgreSQL, SQLSTATE, query, bind, URI, signature, hash ou payload n'est retenu.
+
+## 11. Surface backend
+
+`PostgresBackend` expose désormais en plus :
+
+```text
+persist_raw_transaction_acquisition
+record_raw_transaction_observation
+```
+
+Les traits `RawTransactionWrite` / `RawTransactionObservationWrite` ne sont pas encore implémentés directement : la tranche finale des six traits attend `list_raw_transactions` en `pre.006`, puis la rétention mutante en `pre.007` et le dispatch façade en `pre.008`.
+
+## 12. Tests déterministes
+
+Le miroir `unit_tests/raw_transaction.rs` couvre en plus :
+
+```text
+pré-I/O réseau + référence acquisition exacte
+égalité canonique stricte
+même hash mais payload différent -> Conflict
+tombstone compatible -> Purged match
+tombstone divergent -> Conflict
+mapping exact des origins d'observation
+```
+
+Les canaris d'intégration figent :
+
+```text
+INSERT unique direct sans has_*
+FOR UPDATE après collision
+observation unique idempotente
+ForceRehydrate limité à UPDATE
+aucun DELETE
+aucune pagination/cursor
+aucune transition retention mutante
+aucune impl complète de trait prématurée
+```
+
+La concurrence PostgreSQL réelle et les preuves de rollback restent réservées au test live `pre.009`.
+
+## 13. Migrations
+
+Aucune ressource de migration n'est modifiée.
+
+Checksums inchangés :
+
+```text

+
+## 1. Base
+
+Base opérateur obligatoire :
+
+```text
+0.3.3-pre.6
+```
+
+Le gate opérateur de `pre.006` a confirmé les audits Rust/Markdown et la compilation de la majorité du workspace, puis a détecté deux défauts locaux dans `ksp-store-postgres-lib` :
+
+```text
+unused import: RawTransactionDecodedCursor
+hardening_completeness.rs: argument never used
+```
+
+Aucun défaut fonctionnel de pagination, cursor ou migration n'a été signalé avant cet arrêt.
+
+## 2. Version
+
+```text

+```
+
+## 3. Corrections
+
+### 3.1 Re-export interne inutilisé
+
+Le re-export crate-root suivant est supprimé :
+
+```text
+RawTransactionDecodedCursor
+```
+
+Le type reste privé dans `raw_transaction::cursor` et continue d'être utilisé directement par le codec qui le produit. Aucun contrat public ou comportement cursor n'est modifié.
+
+### 3.2 Canari de hardening
+
+`pre_009_backend_has_no_env_bypass_or_direct_store_trait_implementation` concatène huit sources backend, dont `schema.rs`, mais son format string ne contenait que sept placeholders. Le format string est corrigé à huit placeholders ; le canari conserve exactement le même périmètre d'inspection.

+# Delta `0.3.3-pre.006` — pagination keyset et cursor V1 RawTransaction
+
+## 1. Base et gate d'entrée
+
+Base opérateur obligatoire :
+
+```text
+0.3.3-pre.5
+```
+
+Le gate opérateur fourni le 2026-08-30 est entièrement vert :
+
+```text
+cargo fmt --all                                      PASS
+scripts/audit_rust_workspace_rules.py               PASS

+cargo check -p ksp-store-lib --no-default-features  PASS
+```
+
+La tranche peut donc ouvrir la pagination sans rouvrir l'écriture atomique acquise en `pre.005`.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.6
+```
+
+## 3. Scope exact
+
+Cette tranche ajoute uniquement la navigation backend PostgreSQL des transactions RAW :
+
+```text
+PostgresBackend::list_raw_transactions
+RawTransactionQuery
+RawPage<RawTransactionReference>
+RawPageCursor backend-private V1
+```
+
+Ne sont pas ouverts :
+
+```text
+transitions Full -> Archived -> Purged
+compare-and-transition de rétention
+implémentations complètes des six traits RawTransaction*
+dispatch ksp-store-lib
+RawAccountState
+worker/job policy
+```
+
+## 4. Ordre physique et keyset
+
+L'ordre total reste celui figé en `pre.001` :
+
+```text
+Ascending  = (slot ASC, signature ASC)
+Descending = (slot DESC, signature DESC)
+```
+
+Les deux requêtes privées utilisent :
+
+```text
+retention_state <> 'purged'
+slot >= start_inclusive si présent
+slot <= end_inclusive si présent
+(slot, signature) > cursor pour Ascending
+(slot, signature) < cursor pour Descending
+LIMIT requested + 1
+```
+
+Aucun `OFFSET` n'est utilisé. La signature 64 octets constitue le tie-breaker déterministe pour plusieurs transactions au même slot.
+
+Le prédicat et l'ordre correspondent à l'index V001 existant :
+
+```text
+ix_ksp_raw_transactions_slot_signature
+ON ksp_raw_transactions (slot, signature)
+WHERE retention_state <> 'purged'
+```
+
+Aucune migration n'est modifiée.
+
+## 5. Cursor V1
+
+Le cursor est implémenté dans un sous-module privé au domaine `raw_transaction`.
+
+Format fixe :
+
+```text
+magic            4 bytes  = KSPT
+version          1 byte   = 1
+last_slot        8 bytes  = u64 big-endian
+last_signature  64 bytes
+binding_digest  32 bytes  = SHA-256
+--------------------------------------
+total          109 bytes
+```
+
+Le digest utilise le domaine séparé :
+
+```text
+KSP/raw-transaction-cursor/v1
+```
+
+Il lie de façon non ambiguë :
+
+```text
+longueur du network + network
+direction
+flag start + start slot si présent
+flag end + end slot si présent
+last_slot
+last_signature
+```
+
+Le digest n'est ni un secret ni un mécanisme d'autorisation. Il sert uniquement à détecter corruption et replay sous un autre contexte de navigation.
+
+Le decode rejette avant `pool.get()` :
+
+```text
+taille != 109
+magic incorrect
+version inconnue
+digest divergent
+network différent
+range différente
+direction différente
+last_slot hors range
+bytes hostiles bornés par RawPageCursor
+```
+
+Ces cas sont classés `PostgresBackendErrorKind::QueryInvalid` avec phase statique uniquement.
+
+## 6. Limite physique réelle
+
+`RawPageLimit` reste sans cap métier KSP.
+
+Le backend doit obtenir une row supplémentaire pour déterminer la présence d'une continuation :
+
+```text
+LIMIT requested + 1
+```
+
+La borne physique exacte retenue sur PostgreSQL est donc :
+
+```text
+requested <= i64::MAX - 1
+```
+
+Une valeur supérieure produit :
+
+```text
+PostgresBackendErrorKind::PageLimitUnsupported
+```
+
+Aucun clamp vers `100`, `500`, `1000` ou une autre taille de worker/job n'est introduit.
+
+## 7. Décodage des pages
+
+Toutes les rows retournées par le statement, y compris la row de probe `limit+1`, passent par le mapping fallible :
+
+```text
+signature BYTEA -> [u8; 64]
+slot NUMERIC(20,0) -> texte décimal -> u64
+```
+
+Une corruption physique n'est donc pas masquée simplement parce qu'elle se trouve sur la row supplémentaire.
+
+Si plus de `requested` rows sont valides :
+
+1. la row de probe est retirée du résultat ;
+2. le cursor est construit depuis la dernière row réellement retournée ;
+3. la page contient exactement au plus `requested` références.
+
+Les tombstones `Purged` ne sont jamais listés.
+
+## 8. Concurrence et snapshot
+
+Chaque page est cohérente au niveau de son statement PostgreSQL, mais la navigation ne prétend pas fournir un snapshot inter-pages.
+
+Une mutation concurrente qui insère une clé ordonnée avant le cursor déjà consommé peut ne pas être vue par cette navigation. Cette propriété est désormais explicitement documentée et n'est pas confondue avec une garantie de replay transactionnel.
+
+## 9. Erreurs sûres
+
+Deux kinds backend supplémentaires sont matérialisés :
+
+```text
+PageLimitUnsupported
+QueryInvalid
+```
+
+Comme les autres erreurs physiques, ils ne conservent que :
+
+```text
+kind
+phase &'static str
+```
+
+Aucun cursor, network hostile, signature, query SQL, bind, SQLSTATE ou texte PostgreSQL n'est rendu.
+
+## 10. Tests et canaris
+
+Les tests unitaires ajoutés couvrent :
+
+```text
+round-trip cursor V1 exact
+109 bytes exacts
+magic/version exacts
+replay autre network
+replay autre direction
+replay autre range
+last_slot hors range
+taille hostile 1/108/109/110/4096
+mutation magic/version/digest
+borne page i64::MAX - 1
+rejet i64::MAX
+```
+
+Les canaris d'intégration figent :
+
+```text
+keyset > / <
+ASC/DESC total
+pas d'OFFSET
+exclusion Purged
+index V001 compatible
+pas de cap 500/1000
+pas de DELETE
+pas de transition de rétention
+pas d'implémentation complète de trait prématurée
+```
+
+La pagination PostgreSQL réelle multi-page avec ties/ranges reste réservée au gate live opt-in `pre.009`.
+
+## 11. Migrations
+
+Les migrations sont byte-identiques à `pre.005` :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450
+V001 31488cda2f08f3f46c4cdbdbb6c18c243662fada02eac4487040c8735d72cc51
+```
+
+V001 conserve exactement :
+
+```text
+4 tables
+35 contraintes
+1 index
+40 ressources
+```
+

+# Delta `0.3.3-pre.007-fix.001` — correction du canari de scope rétention
+
+## 1. Base
+
+Base opérateur obligatoire :
+
+```text
+0.3.3-pre.7
+```
+
+Le gate opérateur du 2026-08-30 est vert sur les audits, `cargo check`, Clippy, Store API, Store façade et Config. Il échoue uniquement dans :
+
+```text
+cargo test -p ksp-store-postgres-lib
+```
+
+sur le canari historique :
+
+```text
+pre_005_raw_write_sql_is_atomic_idempotent_and_keeps_later_scope_closed
+```
+
+Ce canari interdisait globalement `DELETE FROM` dans `raw_transaction.rs`. Cette interdiction était correcte en `pre.005`, mais elle devient obsolète en `pre.007` puisque `Archived -> Purged` doit supprimer atomiquement le payload archive.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.7.fix.1
+```
+
+## 3. Correction
+
+Le canari `pre.005` est renommé pour refléter le contrat qui reste valide :
+
+```text
+pre_005_raw_write_sql_is_atomic_idempotent_and_keeps_direct_trait_scope_closed
+```
+
+Il conserve toutes les preuves `pre.005` d'insertion/idempotence/rehydration et continue d'interdire :
+
+```text
+impl ksp_store_api::RawTransactionWrite
+impl ksp_store_api::RawTransactionObservationWrite
+```
+
+Il n'interdit plus globalement `DELETE FROM`, car ce SQL appartient désormais légitimement à la tranche `pre.007`.
+
+Le canari `pre.007_raw_retention_is_atomic_compare_and_transition_without_fake_compaction` reste inchangé et exige explicitement :
+
+```text
+DELETE_ARCHIVE_PAYLOAD_SQL
+DELETE FROM ksp_raw_transaction_archive_payloads
+UPDATE_PURGED_TRANSACTION_SQL
+```
+
+Aucun garde-fou fonctionnel n'est donc supprimé : il est simplement rattaché à la tranche qui possède désormais cette responsabilité.

+Cette tranche ajoute uniquement le bridge backend PostgreSQL de transition :
+
+```text
+PostgresBackend::transition_raw_transaction_retention
+Full -> Archived
+Archived -> Purged
+compare-and-transition
+Compacted unsupported
+```
+
+Ne sont pas encore ouverts :
+
+```text
+implémentations complètes des six traits RawTransaction*
+dispatch ksp-store-lib
+RawAccountState
+worker/job policy
+```
+
+## 4. Pré-I/O
+
+Avant `pool.get()` :
+
+- le réseau de `transition.reference()` doit égaler le binding backend ;
+- si `expected` ou `target` vaut `Compacted`, le backend retourne `RetentionCompactionUnsupported` ;
+- le code KSP stable reste `store.postgres_retention_compaction_unsupported`.
+
+Aucune ligne `retention_state = 'compacted'` n'est créée et aucune dépendance de compression n'est ajoutée.
+
+## 5. Compare-and-transition
+
+Sous transaction PostgreSQL, le canonical est lu avec `FOR UPDATE`. Sa forme physique est validée avant de retourner un outcome ou de muter :
+
+```text
+current == target   -> AlreadyAtTarget
+current != expected -> ExpectedStateMismatch
+Full + expected Full + target Archived       -> archive
+Archived + expected Archived + target Purged -> purge
+```
+
+Une référence absente est `ReferenceNotFound`. Aucun succès n'est rendu avant commit.
+
+## 6. `Full -> Archived`
+
+La transition :
+
+1. exige un payload hot non vide et borné ;
+2. exige l'absence d'une archive résiduelle ;
+3. insère les octets exacts dans `ksp_raw_transaction_archive_payloads` ;
+4. met `payload = NULL` et `retention_state = 'archived'` sur le canonical ;
+5. commit les deux opérations ensemble.
+
+Aucun état `Archived` sans payload archive n'est committé par KSP.
+
+## 7. `Archived -> Purged`
+
+La transition :
+
+1. exige l'absence de payload hot et la présence d'un payload archive valide ;
+2. supprime la ligne archive ;
+3. met `block_time_unix_millis = NULL`, `payload = NULL` et `retention_state = 'purged'` ;
+4. conserve signature, slot, format id/version et content hash ;
+5. commit atomiquement.
+
+Le tombstone reste donc limité aux cinq champs du contrat API.
+
+## 8. Races croisées
+
+Les acquisitions/idempotence/ForceRehydrate de `pre.005` et les transitions de cette tranche verrouillent la même ligne canonical avant mutation. Les races archive/purge/rehydrate sont donc sérialisées ; la preuve concurrente PostgreSQL réelle reste réservée à `pre.009`.
+
+## 9. Erreurs
+
+La classification backend ajoute :
+
+```text
+RetentionCompactionUnsupported
+```
+
+Les autres classifications réutilisées sont :
+
+```text
+WrongNetwork
+ReferenceNotFound
+DataInvalid
+WriteFailed
+```
+
+Aucun texte serveur, SQLSTATE, query ou bind n'est retenu.
+
+## 10. Migrations
+
+Aucune ressource V000/V001 n'est modifiée. Les checksums attendus restent :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450

+## 1. Base
+
+Base opérateur obligatoire :

+```text
+0.3.3-pre.8
+```
+
+Le gate opérateur du 2026-08-30 passe les audits, `cargo check`, les tests Store API/Store/PostgreSQL/Config et `--no-default-features`. Clippy ne bloque pas le build, mais signale deux warnings :
+
+```text

+```
+
+Ils concernent uniquement les helpers génériques de preuve de traits dans :
+
+```text

+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.8.fix.1
+```
+
+## 3. Correction
+
+Les deux helpers conservent exactement les six bounds `RawTransaction*` et matérialisent désormais le paramètre de type dans leur corps avec :
+
+```rust
+let _marker = std::marker::PhantomData::<T>;
+```
+
+Cette forme :

+- conserve une preuve purement compile-time ;

+# Delta `0.3.3-pre.008` — conformance capabilities et dispatch Store
+
+## 1. Base et gate d'entrée
+
+Base opérateur obligatoire :
+
+```text
+0.3.3-pre.7.fix.1
+```
+
+Le gate opérateur fourni le 2026-08-30 est entièrement vert : audits Rust/Markdown, workspace check, Clippy, tests Store API/façade/PostgreSQL/Config et `ksp-store-lib --no-default-features` passent. `pre.007` est donc acquise.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.8
+```
+
+## 3. Six capabilities sur `PostgresBackend`
+
+`PostgresBackend` implémente désormais directement :
+
+```text
+RawTransactionRead
+RawTransactionWrite
+RawTransactionObservationRead
+RawTransactionObservationWrite
+RawTransactionRetentionRead
+RawTransactionRetentionWrite
+```
+
+Les implémentations adaptent les méthodes physiques déjà acquises en `pre.004` à `pre.007` vers `StoreApiFuture` et `ksp_store_api::Result`. Aucun SQL n'est déplacé hors du backend et aucune capability `RawAccount*` n'est ouverte.
+
+## 4. Six dispatches sur `Store`
+
+`Store` implémente les mêmes six traits et dispatch vers `StoreRuntime::Postgres` lorsque la feature `postgres` est compilée. Aucun type `PostgresBackend`, pool, client, row, statement ou SQL n'entre dans la surface publique de `ksp-store-lib`.
+
+Les consumers ordinaires continuent donc à dépendre uniquement de `ksp-store-lib`.
+
+## 5. Validation réseau pré-I/O
+
+La façade valide avant dispatch toutes les opérations dont l'input porte un réseau :
+
+```text
+get/list transaction
+persist acquisition
+record observation
+retention read
+retention transition
+```
+
+Une divergence retourne `store.wrong_network` sans rendre le réseau hostile. `RawTransactionObservationRead` reçoit uniquement une `RawObservationKey`; son scope réseau est celui de l'instance Store mono-réseau.
+
+## 6. Taxonomie d'erreurs stabilisée
+
+```text
+Conflict                       -> store_api.raw_conflict
+QueryInvalid                   -> store_api.raw_query_invalid
+WrongNetwork                   -> store.wrong_network
+ReferenceNotFound              -> store.raw_reference_not_found
+ReadFailed                     -> store.postgres_read_failed
+WriteFailed                    -> store.postgres_write_failed
+DataInvalid                    -> store.postgres_data_invalid
+PageLimitUnsupported           -> store.postgres_page_limit_unsupported
+RetentionCompactionUnsupported -> store.postgres_retention_compaction_unsupported
+```
+
+Le mapping conserve seulement backend, réseau propre de l'instance et phase statique. Aucun SQLSTATE, SQL, bind ou texte serveur n'est exposé.
+
+## 7. Feature mismatch
+
+Le contrat `default = ["postgres"]` reste inchangé. Sans default feature, `Store::open` conserve le rejet pré-I/O `store.backend_not_compiled`; le gate `cargo check -p ksp-store-lib --no-default-features` reste obligatoire.
+
+## 8. Migrations

+
+## 1. Base et constat
+
+Base opérateur :
+
+```text
+0.3.3-pre.9
+```
+
+Le gate standard fourni le 2026-08-30 est propre sur les audits Rust/Markdown, `ksp-store-api`, `ksp-store-lib`, `ksp-config-lib` et `ksp-store-lib --no-default-features`, mais `ksp-store-postgres-lib` ne compile pas son nouveau test live :
+
+```text
+E0502: cannot borrow `*admin` as immutable because it is also borrowed as mutable
+```
+
+Le scénario cancellation stockait le résultat de `admin.transaction().await` dans `lock_transaction_result`. Ce `Result<Transaction<'_>>` pouvait conserver l'emprunt mutable de `admin` jusqu'à sa destruction en fin de fonction, alors que le probe final `transaction_exists(admin, ...)` demande ensuite un emprunt immuable.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.1
+```
+
+## 3. Correction
+
+Le test live matche désormais directement :
+
+```rust
+let lock_transaction = match admin.transaction().await {
+    ...
+};
+```
+
+Le binding intermédiaire `lock_transaction_result` est supprimé. Après `lock_transaction.rollback().await`, la transaction est consommée et l'emprunt mutable de `admin` peut se terminer avant le probe final.
+
+Aucune logique de preuve n'est modifiée : le test conserve le verrou observation réel, le blocage de l'acquisition concurrente, `JoinHandle::abort()`, le rollback du lock administrateur puis la vérification d'absence du canonical annulé.

+
+## 1. Base et constat
+
+Base opérateur :
+
+```text
+0.3.3-pre.9.fix.1
+```
+
+Le gate standard du 2026-08-30 confirme que le borrow `E0502` de `pre.009-fix.001` est corrigé : `cargo check --workspace`, les tests `ksp-store-api`, `ksp-store-lib`, `ksp-store-postgres-lib`, `ksp-config-lib` et `cargo check -p ksp-store-lib --no-default-features` passent.
+
+Clippy bloque encore le nouveau test live sur trois closures soumises à `clippy::implicit_return = deny` et remonte deux `redundant_guards` sur les tableaux de pagination.
+
+Le premier essai live avec le placeholder littéral `<URI_POSTGRES_DEDIEE>` échoue logiquement à `admin_config` et n'est pas une preuve. Le second essai avec une URI dédiée réelle atteint PostgreSQL 17 puis échoue à `backend_open`. Cette étiquette était trop agrégée : elle supprimait le `phase()` statique, pourtant secret-safe, déjà porté par `PostgresBackendError`.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.2
+```
+
+## 3. Corrections Clippy
+
+Les trois filtres utilisent désormais un `return` explicite dans leur closure, conformément à la policy KSP :
+
+```rust
+.filter(|value| return matches_inserted(value))
+.filter(|value| return matches_already_present(value))
+```
+
+Les deux validations de pagination utilisent directement le pattern tableau :
+
+```rust
+Result::Ok([50, 51, 52, 53, 54])
+Result::Ok([54, 53, 52, 51, 50])
+```
+
+Aucune exemption Clippy n'est ajoutée.
+
+## 4. Diagnostic live secret-safe
+
+`open_backend` distingue désormais :
+
+- succès backend ;
+- erreur backend : `LiveFailure::new(error.phase())` ;
+- erreur locale de préparation : propagation du `LiveFailure` existant.
+
+`PostgresBackendError::phase()` est une chaîne statique KSP. Elle ne contient ni URI, ni texte serveur PostgreSQL, ni SQL, ni SQLSTATE, ni bind. Le live peut donc identifier une étape telle que `schema_resource_post_apply`, `store_identity_*`, `history_insert`, etc. sans affaiblir la redaction.
+
+Ce correctif ne modifie volontairement aucune logique de migration tant que la phase réelle n'est pas connue.
+
+## 5. Hors scope / invariants
+
+Aucun changement de :
+
+- production `ksp-store-postgres-lib` ;

+
+## 1. Base et constat
+
+Base opérateur :
+
+```text
+0.3.3-pre.9.fix.2
+```
+
+Le gate standard fourni le 2026-08-30 est entièrement propre : audits Rust/Markdown, `cargo check --workspace`, Clippy all-targets, tests Store/API/backend/Config et `--no-default-features` passent.
+
+Le live PostgreSQL réel atteint PostgreSQL 17 puis échoue pendant `PostgresBackend::open` avec la phase :
+
+```text
+schema_resource_post_apply
+```
+
+Cette phase prouve qu'une ressource V001 a bien été exécutée mais que l'introspection immédiate la classe ensuite `Missing` ou `Incompatible`. Elle ne permet toutefois pas encore de savoir quelle ressource parmi les 40 est concernée.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.3
+```
+
+## 3. Diagnostic post-apply exact et secret-safe
+
+Dans `ensure_resource`, le seul chemin `post_apply_incompatible` conserve `MigrationMismatch` mais utilise désormais :
+
+```rust
+resource.id
+```
+
+comme `PostgresBackendError::phase()`.
+
+`SchemaResource::id` est une chaîne `&'static str` embarquée dans le binaire et contrôlée par KSP, par exemple :
+
+```text
+tables/002_ksp_raw_transactions.sql
+constraints/006_ck_ksp_raw_transactions_slot.sql
+indexes/001_ix_ksp_raw_transactions_slot_signature.sql
+```
+
+Elle ne contient aucune URI, valeur de configuration, donnée utilisateur, SQLSTATE, bind, texte serveur ou payload. Le prochain live peut donc identifier exactement la ressource fautive sans affaiblir la redaction.
+
+Les autres phases de migration restent inchangées.
+
+## 4. Pourquoi aucune correction SQL n'est appliquée ici
+
+Le live ne fournit encore que la classification `schema_resource_post_apply`. V000 est déjà acquis sur PostgreSQL 17 et aucune incompatibilité évidente ne justifie de modifier à l'aveugle une ressource V001 ou son comparateur de catalogue.
+
+`fix.003` est donc volontairement diagnostique : la prochaine exécution doit donner l'identifiant exact, puis le correctif suivant pourra cibler le contrat d'introspection ou la ressource concernée avec preuve.
+
+## 5. Invariants
+
+Aucun changement de :
+
+- fichiers SQL V000/V001 ;
+- ordre ou nombre des 40 ressources V001 ;
+- checksums migrations ;

+# Delta `0.3.3-pre.009-fix.004` — normalisation du CHECK NUMERIC déparsée par PostgreSQL 17
+
+## 1. Base et diagnostic réel
+
+Base opérateur :
+
+```text
+0.3.3-pre.9.fix.3
+```
+
+Le gate standard fourni le 2026-08-30 est entièrement propre. Le live PostgreSQL réel atteint PostgreSQL 17 puis identifie précisément la ressource V001 rejetée après application :
+
+```text
+constraints/006_ck_ksp_raw_transactions_slot.sql
+```
+
+La ressource crée :
+
+```sql
+CHECK (slot >= 0 AND slot <= 18446744073709551615)
+```
+
+La colonne `slot` est `NUMERIC(20,0)`. PostgreSQL peut déparser un littéral `NUMERIC` hors plage bigint sous forme quotée avec cast explicite, notamment :
+
+```text
+'18446744073709551615'::numeric
+```
+
+L'ancien `normalize_catalog_sql` supprimait `::numeric` mais conservait les quotes simples. Le contrat embarqué devenait donc `18446744073709551615` tandis que le catalogue pouvait devenir `'18446744073709551615'`, ce qui produisait un faux `Incompatible` immédiatement après création.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.4
+```
+
+## 3. Correction d'introspection
+
+`schema.rs` ajoute une normalisation ciblée avant la normalisation générale :
+
+- seules les chaînes composées d'un signe ASCII optionnel et de chiffres ASCII ;
+- uniquement lorsqu'elles sont immédiatement suivies de `::numeric` ;
+- voient leurs quotes simples et leur cast `::numeric` retirés dans cette étape ciblée ;
+- les autres casts continuent d’être traités par la normalisation existante.
+
+Cette règle ne retire donc pas les quotes des littéraux métier/textuels tels que :
+
+```text
+'full'::text
+'archived'::text
+'purged'::text
+```
+
+Le canari unitaire existant du CHECK `slot` couvre désormais explicitement la forme PostgreSQL 17 quotée et vérifie également qu'un littéral texte conserve ses quotes.
+
+## 4. Pourquoi la migration reste inchangée
+
+Le SQL V001 est sémantiquement correct et PostgreSQL l'applique avant que KSP ne le rejette. Le défaut est donc dans l'équivalence du catalogue, pas dans la contrainte elle-même. Modifier la ressource SQL ferait inutilement varier le checksum V001 et réécrirait le contrat de migration pour un problème de déparsing.
+
+`fix.004` ne modifie donc aucune ressource V000/V001.
+
+## 5. Invariants
+
+Aucun changement de :
+
+- tables, contraintes ou indexes V001 ;
+- ordre ou nombre des 40 ressources V001 ;
+- Store API / façade ;
+- RawTransaction read/write/pagination/rétention ;
+- cursor ;
+- Config ;
+- scope `RawAccountState`.
+
+Checksums attendus inchangés :

+# Delta `0.3.3-pre.009-fix.005` — canonicalisation des littéraux numériques/intégraux PostgreSQL
+
+## 1. Base et diagnostic réel
+
+Base opérateur :
+
+```text
+0.3.3-pre.9.fix.4
+```
+
+Le gate standard `pre.009-fix.004` fourni le 2026-08-30 est entièrement propre. Le live PostgreSQL 17 confirme que la correction du CHECK `slot` est effective puis avance jusqu'à la ressource suivante :
+
+```text
+constraints/007_ck_ksp_raw_transactions_block_time.sql
+```
+
+La ressource crée :
+
+```sql
+CHECK (
+    block_time_unix_millis IS NULL
+    OR block_time_unix_millis >= 0 AND block_time_unix_millis <= 253402300799999
+)
+```
+
+`block_time_unix_millis` est `BIGINT`. `pg_get_constraintdef` reconstruit une expression depuis la représentation catalogue au lieu de restituer le texte SQL original ; une constante entière typée peut donc apparaître avec un cast explicite. La normalisation de `fix.004` savait retirer les quotes uniquement pour `::numeric` et pouvait encore considérer comme différente une forme telle que :
+
+```text
+'253402300799999'::bigint
+```
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.5
+```
+
+## 3. Correction d'introspection
+
+`schema.rs` généralise la canonicalisation ciblée des littéraux entiers quotés. Une chaîne n'est déquotée que si :
+
+- elle est constituée d'un signe ASCII optionnel suivi uniquement de chiffres ASCII ;
+- elle est immédiatement suivie d'un cast numérique/intégral PostgreSQL retenu ;
+- le cast appartient à `numeric`, `bigint`, `integer`, `smallint`, `int8`, `int4` ou `int2`.
+
+Les casts équivalents non quotés sont également supprimés par la normalisation générale.
+
+Cette règle reste volontairement distincte des littéraux métier/textuels :
+
+```text
+'full'::text
+'archived'::text
+'purged'::text
+```
+
+conservent leurs quotes dans la forme normalisée.
+
+## 4. Canaris
+
+Le test d'équivalence catalogue couvre désormais :
+
+- le CHECK `slot` avec `'18446744073709551615'::numeric` ;
+- le CHECK `block_time` avec `'0'::bigint` et `'253402300799999'::bigint` ;
+- l'alias intégral `::int8` sur la borne `format_version` ;
+- la préservation du littéral texte `'full'::text`.
+
+Le but est de normaliser des représentations typées équivalentes, jamais de rendre un CHECK divergent compatible.
+
+## 5. Pourquoi V001 reste inchangée
+
+Comme pour `slot`, PostgreSQL applique la contrainte avant que KSP ne la rejette lors de la relecture post-apply. Le défaut reste donc dans l'équivalence de catalogue. Modifier le SQL V001 créerait une migration logique différente sans corriger la cause.
+
+Checksums attendus inchangés :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450

+
+## 6. Scope

+Aucun changement de :
+
+- ressource SQL V000/V001 ;
+- ordre/nombre des 40 ressources V001 ;

+# Delta `0.3.3-pre.009-fix.006` — restauration `schema.rs` et classification du drift appliqué
+
+## 1. Base et diagnostic
+
+Base opérateur :
+
+```text
+0.3.3-pre.9.fix.5
+```
+
+Deux faits distincts sont corrigés.
+
+Premièrement, l'overlay `pre.009-fix.005` a accidentellement tronqué la fin de `crates/ksp-store-postgres-lib/src/schema.rs` lors de la généralisation de la normalisation PostgreSQL. Les éléments privés suivants avaient disparu de l'archive alors qu'ils restent requis :
+
+```rust
+fn schema_incompatible<T>(phase: &'static str) -> std::result::Result<T, crate::PostgresBackendError>
+fn schema_query_error<T>(phase: &'static str) -> std::result::Result<T, crate::PostgresBackendError>
+
+#[cfg(test)]
+#[path = "../unit_tests/schema.rs"]
+mod tests;
+```
+
+L'opérateur les a restaurés et le gate standard est redevenu entièrement propre. `fix.006` réembarque explicitement le fichier complet afin que l'historique d'overlays soit autonome.
+
+Deuxièmement, le live PostgreSQL 17 progresse maintenant jusqu'au scénario qui supprime volontairement l'index géré puis rouvre le backend avec `schema_autoupdate=false`. Le backend renvoyait `MigrationFailed`, alors que le contrat live attend `MigrationMismatch`.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9.fix.6
+```
+
+## 3. Classification corrigée
+
+Dans `verify_or_repair_applied_migrations`, une ressource `Missing` d'une migration déjà présente dans l'historique signifie que l'état physique ne correspond plus au schéma déclaré. Lorsque `schema_autoupdate=false`, KSP ne tente aucune réparation et retourne désormais :
+
+```text
+PostgresBackendErrorKind::MigrationMismatch
+phase = schema_autoupdate_disabled
+```
+
+Cette correction est volontairement limitée à ce chemin. Les cas où aucune divergence appliquée n'existe mais où une mutation est interdite par policy, notamment `migration_pending` ou `schema_autocreate_disabled`, restent classés `MigrationFailed`.
+
+## 4. Canari
+
+Un helper privé `schema_autoupdate_disabled_error()` centralise la classification et le test unitaire vérifie exactement :
+
+```text
+kind  = MigrationMismatch
+phase = schema_autoupdate_disabled
+```
+
+## 5. Migrations inchangées
+
+Aucun SQL V000/V001 n'est modifié. Checksums attendus inchangés :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450

+# Delta `0.3.3-pre.009` — preuve PostgreSQL live complète RawTransaction
+
+## 1. Base et gate d'entrée
+
+Base opérateur obligatoire :
+
+```text
+0.3.3-pre.8.fix.1
+```
+
+Le gate opérateur fourni le 2026-08-30 est entièrement propre : audits Rust/Markdown, `cargo check --workspace`, Clippy all-targets sans warning, tests Store API/façade/PostgreSQL/Config et `ksp-store-lib --no-default-features` passent. `pre.008-fix.001` est donc acquise.
+
+## 2. Version
+
+```text
+workspace.package.version = 0.3.3-pre.9
+```
+
+## 3. Nouveau test PostgreSQL réel
+
+La tranche ajoute :
+
+```text
+crates/ksp-store-postgres-lib/tests/postgres_raw_transaction_live.rs
+```
+
+Le test est `#[ignore]`, lit une URI PostgreSQL dédiée uniquement sur `stdin`, ne l'affiche jamais et refuse de démarrer lorsqu'une table KSP V000/V001 existe déjà. Il ne nettoie que le schéma qu'il a prouvé absent avant son propre bootstrap.
+
+Il refuse PostgreSQL < 15 comme la preuve fondation existante.
+
+## 4. Migration, identité réseau et schema update
+
+La preuve couvre :
+
+- bootstrap V000 + V001 sur base vide ;
+- health Ready avec migration 1 ;
+- refus d'une réouverture sous un autre `RawNetworkId` ;
+- réouverture idempotente ;
+- suppression contrôlée de `ix_ksp_raw_transactions_slot_signature` ;
+- `schema_autoupdate=false` qui bloque le drift ;
+- `schema_autoupdate=true` qui recrée et revalide l'index manquant.
+
+Aucune ressource de migration n'est modifiée et aucun historique n'est réécrit.
+
+## 5. Écriture, idempotence, concurrence et rollback
+
+Le live couvre :
+
+- canonical + observation atomiques ;
+- get canonical exact ;
+- observation round-trip exact avec provenance complète ;
+- deux acquisitions identiques en vraies tâches concurrentes : un `Inserted`, un `AlreadyPresent` ;
+- deux acquisitions divergentes sous la même signature : un gagnant et un `Conflict` ;
+- vérification qu'une seule observation du duel divergent est durable ;
+- observation supplémentaire `Inserted` puis `AlreadyPresent` ;
+- même observation key divergente -> `Conflict` ;
+- collision observation pendant une nouvelle acquisition -> rollback du canonical nouvellement tenté.
+
+## 6. Pagination
+
+Le test insère cinq signatures sur trois slots, dont deux paires ex æquo, et prouve :
+
+```text
+Ascending  50, 51, 52, 53, 54
+Descending 54, 53, 52, 51, 50
+page size  2
+```
+
+Il rejoue ensuite le cursor V1 sous :
+
+- direction différente ;
+- range différente.
+
+Les deux cas doivent être `QueryInvalid`.
+
+## 7. Rétention et rehydrate
+
+La preuve couvre :
+
+- compare mismatch observable ;
+- `Full -> Archived` et lecture exacte depuis archive ;
+- idempotence `AlreadyAtTarget` ;
+- `Archived -> Purged` ;
+- `get -> None` et tombstone minimal exact ;
+- acquisition normale sur tombstone -> `SkippedPurged/NotRecorded` ;
+- ForceRehydrate divergent -> `Conflict` sans mutation ;
+- ForceRehydrate compatible -> `Rehydrated/Inserted` ;
+- `Full -> Compacted` rejeté par `RetentionCompactionUnsupported` sans changement d'état ;
+- deux archives concurrentes puis deux purges concurrentes : un `Applied` et un `AlreadyAtTarget` par race ;
+- rehydrate après la race purge.
+
+## 8. Cancellation réelle
+
+Le test crée une observation durable, la verrouille via une transaction PostgreSQL administrateur, puis démarre une nouvelle acquisition qui :
+
+1. insère son canonical dans sa transaction non committée ;
+2. bloque sur la collision de l'observation verrouillée ;
+3. reste bloquée au-delà du délai canari ;
+4. est annulée via `JoinHandle::abort()` ;
+5. libère ensuite le verrou administrateur ;
+6. prouve que le canonical de l'acquisition annulée n'est pas durable.
+
+Cette preuve exerce un rollback par cancellation réelle, pas une simulation séquentielle.
+
+## 9. Réouverture finale
+
+Après toutes les opérations, le backend est rouvert sur le même réseau. Le test exige :
+
+- health Ready ;
+- migration 1 ;
+- lecture exacte d'un canonical durable antérieur.
+
+Le cleanup final supprime les cinq tables KSP uniquement parce que leur absence initiale a été prouvée.
+
+## 10. Migrations
+
+Aucune ressource V000/V001 n'est modifiée.
+
+Checksums attendus et recalculés :
+
+```text
+V000 d29068b8c13b9dc0cc9ef6aaadd0fa12d41e0fe4c56541a1118c4bfc846a1450
+V001 31488cda2f08f3f46c4cdbdbb6c18c243662fada02eac4487040c8735d72cc51
+```
+
+V001 reste exactement à 40 ressources.
+
+## 11. Fichiers modifiés
+
+```text
+Cargo.toml
+crates/ksp-store-postgres-lib/README.md
+crates/ksp-store-postgres-lib/USAGE.md
+crates/ksp-store-postgres-lib/tests/hardening_completeness.rs

+```
+
