+
+## Objectif
+
+Implémenter strictement la tranche `pre.003` du plan `035` :
+
+```text
+ajouter dans Transport une source latest-value sûre pour les snapshots WebSocket typés
+la déléguer depuis les façades Standard et Helius existantes
+observer les incidents reconnect/overflow dans les sources Standard Logs, Standard Block et Helius du Worker
+ancrer un incident sur le dernier slot réellement observé par cette source
+borner l'incident avec le premier slot post-incident réellement reçu
+conserver une terminalité conservative tant que les tranches de replay/repair ultérieures ne sont pas présentes
+ne créer aucun nouveau socket, actor, retry ou repair HTTP
+```
+
+Cette tranche ne remplace pas encore un gap WebSocket par une réparation. Elle rend l'incident explicitement observable et bornable en réutilisant exclusivement les snapshots déjà publiés par l'actor Transport existant.
+
+## Transport — source latest-value WebSocket
+
+`WsSession` possède déjà un `tokio::sync::watch::Receiver<WsSessionSnapshot>` interne utilisé pour `snapshot()` et `state()`.
+
+`pre.003` ajoute `WsSessionSnapshotSource`, un observateur cloneable qui encapsule uniquement un clone de ce receiver et expose :
+
+```text
+current() -> dernier WsSessionSnapshot sûr
+wait_for_change() -> prochaine valeur latest-value, ou None si l'actor disparaît
+```
+
+Le type ne contient ni URL, ni credentials, ni socket, ni payload de notification. Son `Debug` reste fondé sur la projection sûre existante.
+
+`WsSession::snapshot_source()` clone le receiver existant. Les façades :
+
+```text
+SolanaStandardWsSession
+HeliusLaserStreamWsSession
+```
+
+délèguent cette méthode au même `WsSession` physique. Aucun second runtime WebSocket n'est créé.
+
+## Worker — ancre d'incident WebSocket
+
+Le Worker introduit un contrat crate-private `RawTransactionIngestWebSocketIncidentAnchor`.
+
+Il conserve uniquement :
+
+```text
+start_slot
+end_slot optionnel
+compteurs de continuity gap / overflow observés au moment de l'incident
+motifs reconnect et/ou overflow
+```
+
+La borne de début respecte le plan `035` :
+
+```text
+start_slot = dernier slot réellement observé par la source avant l'incident
+```
+
+Aucun timestamp, frontier dérivé d'une autre source ou `last_slot + 1` n'est utilisé comme preuve de début.
+
+La borne de fin est :
+
+```text
+end_slot = premier slot réellement reçu par la même source après l'incident
+```
+
+Le range reste inclusif. Les validations réutilisent les bornes run-local introduites en `pre.002` et rejettent notamment inversion, dépassement de plage et compteur régressif.
+
+Si un reconnect/overflow est observé avant qu'un slot source n'ait été vu, le Worker ne fabrique pas d'historique : l'incident est `source.websocket_incident_unbounded`.
+
+## Worker — observation des snapshots
+
+`RawTransactionIngestProcessingFrontierReporter` observe maintenant les `WsSessionSnapshot` Transport et maintient :
+
+```text
+continuity gap total WebSocket
+notification overflow total
+ancre d'incident WebSocket éventuelle
+projection de lifecycle source
+```
+
+Une source redevenue `Active` reste projetée `Reconnecting` tant qu'un incident ouvert n'a pas reçu sa borne post-incident. Cela évite de publier transitoirement une continuité saine alors que le gap n'est pas encore borné.
+
+Aucune mutation de la politique de reconnect Transport n'est effectuée par le Worker.
+
+## Standard Logs et Helius transaction
+
+Les deux sources réutilisent maintenant `session.snapshot_source()` en parallèle de la réception métier et des tâches d'hydration existantes.
+
+Lorsqu'un incident est détecté :
+
+```text
+le premier signal post-incident borne le range de manière inclusive
+ce signal est quand même admis dans le coordinator d'hydration existant
+aucune nouvelle notification n'est admise après cette borne dans pre.003
+les signaux/tâches déjà admis sont drainés
+la source termine ensuite par source.continuity_gap_proven
+```
+
+Ce séquencement évite de perdre artificiellement le premier événement post-incident tout en restant fail-closed tant que les tranches de repair ne sont pas implémentées.
+
+## Standard Block
+
+La source Standard Block observe le même snapshot latest-value Transport.
+
+Le premier bloc post-incident :
+
+```text
+borne l'incident
+projette et envoie toutes ses ingresses via l'admission centrale existante
+marque ensuite le slot settled
+termine enfin par source.continuity_gap_proven
+```
+
+Un bloc sans transaction qualifiée peut quand même fermer la borne de slot et est settled avant la terminalité conservative.
+
+## Yellowstone
+
+Le chemin Yellowstone existant reste inchangé fonctionnellement dans cette tranche :
+
+```text
+aucune mutation Worker de from_slot
+aucun ownership Worker de SubscribeReplayInfo
+aucune nouvelle tentative de replay
+aucune modification du contrat Transport Yellowstone
+```
+
+La preuve de replay native et la distinction `replay_attempt` / couverture effective restent réservées à `pre.004`.
+
+## Tests ajoutés/étendus
+
+Transport couvre :
+
+```text
+source latest-value courante
+publication d'un changement
+fermeture de la source lorsque l'actor publisher disparaît
+accessibilité crate-root de WsSessionSnapshotSource
+présence des délégations Standard/Helius
+réutilisation du watch actor existant sans second runtime
+```
+
+Worker couvre :
+
+```text
+ancre inclusive et bornée
+extension monotone d'un incident reconnect/overflow
+rejet d'un incident sans motif
+rejet de range inversé ou surdimensionné
+incident sans slot précédent -> erreur explicite
+compteurs WebSocket régressifs -> erreur explicite
+reconnect et overflow successifs -> même ancre la plus ancienne
+absence de socket/retry/from_slot possédé par le Worker

+le premier slot source post-incident est la borne de fin inclusive
+aucune histoire antérieure n'est inventée sans ancre source
+le premier événement post-incident est admis avant la terminalité conservative
+pre.003 reste fail-closed et ne prétend pas encore réparer le gap
+```
+
+## Questions ouvertes
+
+```text
+aucune pour pre.003

+
+## Tranche suivante
+
+`pre.004` reste dédiée à la preuve de replay natif Yellowstone : qualification de `SubscribeReplayInfo`, preuve de couverture effective et conservation stricte de l'ownership `from_slot` dans Transport.
