+.SYNOPSIS
+  Protocole de reimport sous controle renforce (Docs/Migration/05_Correctifs_Isoles.md, section 3),
+  etapes 1 a 6, pour un correctif applique par commandlet.
+
+.DESCRIPTION
+  1. tag git <Id>-avant + Snapshot des assets cibles
+  2. photographie avant (LPDumpFunction) de chaque graphe cible
+  3. simulation -DryRun ; arret si le nombre de lignes de rapport attendues n'est pas atteint
+  4. application reelle
+  5. photographie apres + diff
+  6. LPCheckMeshAssignment + CompileAllBlueprints
+  Les preuves vont dans Docs/Migration/etat/<Id>_*. Ne commite pas : la validation reste humaine
+  (lecture du diff), puis journal + commit + tag <Id>-apres.
+
