 /**
  * CollectFlow — Extraction Qlik via Playwright (Chromium headless).
  *
- * Le proxy Qlik refuse un websocket "raw" côté serveur (403), mais l'accepte
- * depuis une vraie session navigateur. On ouvre donc l'app dans Chromium
- * (auth NTLM via httpCredentials, comme l'agent hermes), puis on extrait
- * l'hypercube via un websocket Engine **in-page** (même origine = accepté).
+ * Le proxy Qlik refuse un websocket "raw" (403) ET un ws in-page avec xrfkey
+ * arbitraire. On réutilise donc la **session de la page** via la Capability API
+ * Qlik (`require(['js/qlik'])` → `qlik.openApp` → `createCube`), qui gère le ws
+ * et le xrfkey en interne avec la session authentifiée du navigateur.
  *
- * Efficacité : on applique une sélection sur le champ "Article Code" = codes
- * du fournisseur → l'hypercube ne renvoie que ces lignes (pull minimal).
+ * Auth : cookie X-Qlik-Session injecté (obtenu via le flux ticket NTLM côté Node,
+ * fiable) + httpCredentials en secours.
