+# Delta `0.3.14-pre.007` — hydration des références connues
+
+## Base requise
+
+```text
+0.3.14-pre.006
+workspace.package.version = 0.3.14-pre.6
+deltas/0.3.14/pre.006.md présent
+```
+
+## Gate de la base
+
+Le gate opérateur de `0.3.14-pre.006` est validé avant ouverture de cette tranche :
+
+```text
+cargo fmt --all : PASS
+cargo fmt --all -- --check : PASS
+audit Rust workspace rules : PASS
+audit Markdown tables : PASS
+cargo check --workspace : PASS
+cargo clippy --workspace --all-targets --all-features -- -D warnings : PASS
+cargo test -p ksp-worker-raw-transaction-ingest-lib --all-targets --all-features : PASS
+```
+
+Le gate Worker comprend notamment :
+
+```text
+129 unit tests : PASS
+cross_layer_completeness : 8 PASS
+dependency_boundary : 19 PASS
+hardening : 31 PASS
+public_api : 20 PASS
+release_completeness : 8 PASS
+```
+
+## Objectif
+
+Implémenter strictement la tranche `pre.007` du plan `035` :
+
+```text
+réutiliser getTransaction observed pour une référence déjà connue
+réutiliser le registre global de coalescence network/signature/commitment existant
+ne créer aucun second registre d'hydration
+représenter getTransaction = null comme une obligation Missing, jamais comme une preuve d'absence
+conserver exactement le slot déjà observé avec la référence
+préférer le bloc de ce slot lorsque le même rôle HTTP expose getBlock
+ne pas déclencher encore la réconciliation du gap-ledger ni modifier le supervisor
+ne pas ajouter de retry réseau Worker
+```
+
+## Obligation de référence connue
+
+`continuity.rs` matérialise un contrat privé :
+
+```text
+RawTransactionIngestKnownReferenceObligation
+    reference : network + signature déjà observés
+    slot : slot déjà observé
+    commitment : Confirmed ou Finalized exact
+```
+
+Le contrat refuse `Processed` et ne contient aucun état « absent ». Il ne peut donc pas convertir une réponse HTTP `null` en preuve que la transaction n'existait pas.
+
+Cette obligation reste distincte de `TargetCoverage` : `KnownReferences` ne devient toujours jamais une configured target coverage.
+
+## Réutilisation de la coalescence globale
+
+Le chemin productif existant reste fondé sur :
+
+```text
+RawTransactionIngestGlobalHydrationRegistry
+RawTransactionIngestHydrationKey
+    network
+    signature
+    commitment
+fetch_hydration_shared(...)
+fetch_hydration(...)
+HttpTransportPool::get_transaction_observed(...)
+```
+
+Aucun registre `KnownReferenceHydrationRegistry`, semaphore parallèle ou second fanout HTTP n'est ajouté.
+
+Deux demandes concurrentes portant la même clé de référence partagent donc toujours le leader/follower global déjà présent depuis `0.3.13`.
+
+## Résolution de l'hydration
+
+La qualification après `getTransaction observed` devient explicite :
+
+```text
+Available(ingress)
+Missing {
+    obligation,
+    disposition
+}
+```
+
+`Available` réutilise exactement `finalize_hydration` et le pipeline central Common RAW -> admission -> Store existant.
+
+`Missing` conserve la référence et son slot. Il ne produit aucun ingress et ne ferme aucune obligation de continuité.
+
+Le coordinator nominal existant conserve son comportement stable jusqu'à `pre.008` : lorsqu'une notification live ordinaire hydrate vers `null`, son pending de processing est soldé comme auparavant. La nouvelle représentation `Missing` est toutefois la primitive réutilisable par la réconciliation ; `pre.008` décidera explicitement de la conservation dans le gap-ledger au lieu de confondre ce résultat avec une absence prouvée.
+
+## Préférence bloc du slot
+
+Après un `getTransaction = null`, aucune requête bloc n'est lancée automatiquement dans cette tranche.
+
+Le rôle HTTP exact est inspecté sans I/O supplémentaire :
+
+```text
+getBlock supporté sur le même rôle
+    -> PreferBlockSlot
+
+getBlock non supporté
+    -> AwaitCoverage
+```
+
+`PreferBlockSlot` signifie uniquement que le slot déjà connu est la prochaine primitive de matériau à privilégier lors de la réconciliation. Cela n'autorise ni scan historique, ni broadening du scope filtré, ni ingestion de transactions inconnues du bloc.
+
+Le scan/discovery borné de `pre.006` et cette préférence de matériau restent séparés jusqu'à l'unification `pre.008`.
+
+## Tests ajoutés
+
+Les unit tests couvrent :
+
+```text
+obligation connue conservant exactement reference/slot/commitment
+rejet du commitment Processed
+coalescence de deux hydrations concurrentes vers une seule requête getTransaction
+résolution Available vers le pipeline Common RAW existant
+getTransaction = null sans getBlock -> Missing/AwaitCoverage
+getTransaction = null avec getBlock sur le même rôle -> Missing/PreferBlockSlot
+```
+
+Les canaris `hardening` et `release_completeness` garantissent en plus :
+
+```text
+un seul RawTransactionIngestGlobalHydrationRegistry
+aucun second KnownReferenceHydrationRegistry
+réutilisation de fetch_hydration_shared et get_transaction_observed
+aucune nouvelle surface publique
+aucune responsabilité lower-case repair dans crate-root
+```
+
+## Hors périmètre inchangé
+
+```text
+aucune conservation active du Missing dans le gap-ledger avant pre.008
+aucun getBlock fallback exécuté automatiquement dans cette tranche
+aucune modification du supervisor source-loss
+aucune modification de la health policy
+aucun retry réseau Worker parallèle à Transport
+aucune source/provider supplémentaire
+aucun EARLY/shred adapter
+aucun backfill historique caller-driven
