+-- Rivage brisé (carte 1460) — retrait du drapeau UNIT_FLAG2_UNK5
+--
+-- Signalé en jeu : « les démons invoqués c'est ok mais pas les autres au
+-- fond », puis « les fameux démons inattaquables se battent avec les
+-- démons attaquables ». Nommément : Gangreseigneur Rakkan, Légionnaire
+-- gangregarde, Molosse de l'effroi gangrené.
+--
+-- LA CAUSE, et elle est de mon fait
+-- La transposition des modèles depuis le dump de référence a importé
+-- `unit_flags2` sur 147 entrées. Ces trois-là valaient 0 avant ; elles
+-- ont reçu 2097152, soit 0x200000 — UNIT_FLAG2_UNK5 dans notre cœur.
+--
+-- CE QUI REND CE DRAPEAU PARTICULIER : notre serveur l'IGNORE
+-- totalement. Aucune de ses vérifications ne le consulte. Mais le client,
+-- lui, l'interprète et refuse de désigner la créature comme cible.
+--
+-- C'est ce qui explique le symptôme le plus déroutant de la série : une
+-- sonde posée dans `Unit::_IsValidAttackTarget` n'a JAMAIS produit la
+-- moindre ligne pour ces créatures. Le client refusait de lui-même, sans
+-- jamais interroger le serveur. L'absence de trace était l'information.
+--
+-- LA CORRÉLATION QUI TRANCHE
+--   démons INVOQUÉS par le script (attaquables) : unit_flags2 = 0
+--   démons STATIQUES (bloqués) : bit 0x200000 présent
+--   67 entrées, 420 spawns concernés
+--
+-- On retire UNIQUEMENT ce bit, en préservant le reste de la colonne.
+-- Le serveur ne s'en sert pas : ce retrait ne peut rien casser côté
+-- logique, il lève seulement le refus du client.
+--
+-- Retour arrière : chantiers/rivage_brise/retour_unk5_1460.sql
