+# Delta `0.3.2-pre.003-fix.001` — conformité Clippy et canari de frontière Store
+
+## 1. Base requise
+
+Base exacte :
+
+```text
+0.3.2-pre.003
+workspace.package.version = 0.3.2-pre.3
+```
+
+Le gate opérateur fourni le 29 août 2026 confirme :
+
+```text
+cargo fmt --all                                         PASS
+audit Rust général / exports / workspace                PASS
+audit Markdown                                           PASS — 186 tables / 127 files
+cargo check --workspace                                  PASS
+cargo clippy --workspace --all-targets                   FAIL — 5 implicit_return observés dans les tests Store
+cargo test -p ksp-store-api                              PASS
+cargo test -p ksp-store-lib                              FAIL — faux positif dependency_boundary sur PostgresPoolSettings
+cargo test -p ksp-store-lib --no-default-features       FAIL — même faux positif dependency_boundary
+cargo test -p ksp-store-postgres-lib                     PASS
+cargo check -p ksp-store-lib --no-default-features      PASS
+```
+
+Aucun défaut de production/runtime n'est observé : les 6 tests unitaires Store passent dans les deux configurations de feature. Le correctif reste strictement dans le couloir `pre.003`.
+
+## 2. Objet
+
+Corriger exclusivement :
+
+```text
+les closures de tests non conformes à clippy::implicit_return
+le canari dependency_boundary trop large qui interdit le mot générique Pool
+```
+
+Aucune surface API, borne, erreur, lifecycle, feature, dépendance ou comportement Store n'est modifié.
+
+## 3. Clippy `implicit_return`
+
+Les closures de projection de code d'erreur utilisent désormais la forme explicite requise par `RUST-ERR-003` :
+
+```rust
+|value| return value.code()
+```
+
+La correction couvre toutes les occurrences de la tranche, y compris les branches compilées uniquement avec `--no-default-features`.
+
+## 4. Canari de frontière physique
+
+Le test `pre_003_facade_adds_only_backend_neutral_settings_lifecycle_and_api_reexports` interdisait le token nu :
+
+```text
+Pool
+```
+
+Cette condition est incorrecte car `PostgresPoolSettings` est une surface de configuration backend-neutral explicitement prévue par `pre.003`. Elle provoquait donc un faux positif tout en ne prouvant pas mieux l'absence de fuite physique.
+
+Le canari interdit désormais les chemins/types physiques ciblés :
+
+```text
+pub use ksp_store_postgres_lib
+tokio_postgres
+deadpool_postgres
+rustls::
+deadpool::managed::Pool
+tokio_postgres::Client
+tokio_postgres::Row
+tokio_postgres::Statement
+```
+
+Les protections existantes sur le manifeste et les production sources restent inchangées.
+
+## 5. Version Cargo
+
+Le correctif modifie des fichiers Rust de tests consommés par le build. Conformément à `VER-ID-007` et `VER-ID-010` :
+
+```text
+workspace.package.version = 0.3.2-pre.3.fix.1
+```
+
+Livraison :
+
+```text
+0.3.2-pre.003-fix.001
+```
+
+## 6. Fichiers modifiés
+
+```text
+Cargo.toml
+crates/ksp-store-lib/tests/dependency_boundary.rs
+crates/ksp-store-lib/tests/feature_mismatch.rs
+crates/ksp-store-lib/unit_tests/settings.rs
+crates/ksp-store-lib/unit_tests/store.rs
+```
+
+Chaque fichier Rust réellement modifié incrémente son header de version une seule fois. Aucun autre fichier source n'est touché.
+
+## 7. Fichier ajouté
+
+```text
+deltas/0.3.2/pre.003-fix.001.md
+```
+
+## 8. Fichiers supprimés
+
+```text
+aucun
+```
+
+## 9. Validations exécutées dans l'environnement de génération
+
+```text
+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/0.3.2
+```
+
+`cargo`, `rustc` et `rustfmt` ne sont pas disponibles dans l'environnement de génération. Aucun gate Cargo n'est donc déclaré PASS ici.
+
+## 10. Gate opérateur requis
+
+```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/0.3.2
+cargo check --workspace
+cargo clippy --workspace --all-targets
+cargo test -p ksp-store-lib
+cargo test -p ksp-store-lib --no-default-features
+cargo test -p ksp-store-postgres-lib
+cargo check -p ksp-store-lib --no-default-features
+```
+
+## 11. Décisions et questions ouvertes
+
+Décision : un canari de fuite backend doit cibler des symboles/chemins physiques, pas interdire des mots génériques faisant partie de settings publics légitimes.
+
+Question ouverte : aucune. Si le gate est vert, la suite reste `0.3.2-pre.004` — Config `std.store`.
