-Objectif : prendre en charge la couche de lancement construite autour de `Meteora DBC` et `Meteora DAMM v2`.
+Réalisé :
 
-À faire :
+- ajout d’un registre des surfaces de lancement,
-
+- ajout d’un registre de clés observables par surface de lancement,
-- ajouter un décodeur dédié `LaunchLab / Fun Launch` lorsque des signatures ou programmes propres sont observables,
+- ajout d’une attribution entre événements/pools détectés et surfaces connues,
-- distinguer les événements de scaffolding / launchpad des événements `DBC` et `DAMM v2`,
+- premier support de `Meteora Fun Launch` comme surface d’origine au-dessus de `Meteora DBC`,
-- relier les lancements `LaunchLab / Fun Launch` aux pools et paires finalement créés,
+- branchement automatique de l’attribution depuis le pipeline de résolution transactionnelle,
-- préparer le suivi des transitions entre lancement, bonding curve et AMM,
+- conservation d’une séparation stricte entre protocole on-chain et origine de lancement.
-- éviter de confondre la couche launchpad avec les programmes DEX sous-jacents.
 
 ### 6.042. Version `0.7.10` — Consolidation multi-DEX
 Objectif : unifier le comportement des connecteurs DEX v1 avant l’ouverture des couches analytiques plus riches.
