- ChatbotV2.vue : Vue island, thread chat (input + messages bot/user), persistance sessionStorage, bandeau beta '120 fiches AEP, RAG-PE bientot', gestion erreurs 429/502/504 ; pas de streaming ni markdown V1 - /api/chatbot.ts : endpoint Astro server proxy POST vers CHATBOT_UPSTREAM (default https://aep.trans-former.fr/api/chatbot), timeout 25s, body { question, history } -> upstream classique chatbot AEP Mistral Small - astro.config.mjs : output 'server' + adapter @astrojs/node standalone (Astro 6 a supprime mode hybrid ; on opt-in prerender sur les pages) - Toutes les pages publiques (index, manifeste, manifeste/commander, a-propos, mentions-legales) ont 'export const prerender = true' - ColCentre.astro : remplace ChatbotPlaceholder par ChatbotV2 dans le tab - .env.example : ajoute CHATBOT_UPSTREAM (V1.5 = switch LightRAG-PE 1 ligne) Decision V1 : endpoint AEP /api/chatbot (classique, repond bien) au lieu de /api/chatbot-v2 qui retourne v2_ready=false ('base vectorielle en cours'). Bandeau beta reste valide ; switch v2 quand ready cote AEP via env var. Note PC8 deploy : Coolify doit booter avec 'node ./dist/server/entry.mjs' (SSR Node standalone) au lieu de servir dist/client/ static. Test end-to-end OK : SSR boot port 4399 + curl POST /api/chatbot -> reponse_texte 800+ chars de l'AEP backend.
