merge: PC7 chatbot v2 AEP + Astro server SSR endpoint (round 3)

feat: PC7 chatbot V1 onglet centre HAUT + endpoint Astro proxy SSR
- 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.

+# Setup Behold pour embeds Insta
+
+Page cerveau col D (`ColInsta.astro`) consomme 2 feeds Insta via [Behold.so](https://behold.so) (gratuit, 2 feeds, sync 1h, sans login user).
+
+## Etapes
+
+1. Creer compte sur https://behold.so (gratuit jusqu'a 2 feeds)
+2. Connecter `@aep.politique` (Login Instagram via Facebook Business)
+3. Connecter `@julesneny` (idem)
+4. Recuperer les 2 feed IDs depuis le dashboard Behold
+5. Copier `.env.example` vers `.env.local` (a la racine du repo)
+6. Remplir `.env.local` :
+
+   ```bash
+   PUBLIC_BEHOLD_AEP=xxxxxxxxxxxx
+   PUBLIC_BEHOLD_JULESNENY=yyyyyyyyyyyy
+   ```
+
+7. Relancer `npm run dev` ou rebuild + redeploy (PC8)
+
+## Comportement par defaut
+
+Sans feed IDs valides (placeholder), le composant `InstaFeed.vue` affiche un fallback gracieux :
+- Titre du compte (lien direct vers Instagram)
+- Bio courte
+- Bouton "Voir sur Instagram"
+
+C'est OK pour un V1 visuel "complet". UX degradee mais pas casse.
+
+## Ressources techniques
+
+- API Behold : `https://feeds.behold.so/{feedId}` -> JSON array de posts
+- Sync : 1h (Behold rafraichit depuis Insta automatiquement)
+- CDN : images servies depuis Behold (pas de hot-link Insta direct)
+
+## CSP (PC8 deploy)
+
+Si une CSP est ajoutee au deploy Caddy, prevoir :
+
+```
+connect-src 'self' https://feeds.behold.so;
+img-src 'self' data: https://feeds.behold.so https://*.cdninstagram.com;
+```
+
+## Alternatives si Behold ne convient pas
+
+- **EmbedSocial** (~$8/mois) : https://embedsocial.com
+- **Scrape n8n nocturne** (V1.5) : Insta Graph API via compte Business + Page Facebook ; coherent avec PC6 journal-aggregate
+- **Posts manuels oEmbed** (V2) : Jules selectionne 6-10 URLs, oEmbed post-by-post

+# PC6 — Setup journal unifié + n8n workflow
+
+Spec : `0 INBOX/PROMPTS/page-cerveau-build/PROMPT-PC6-journal-n8n.md`
+Pilote : `0 INBOX/PROMPTS/page-cerveau-build/PILOTE-PC.md` (delta 5, delta 15)
+
+## TL;DR
+
+Le journal de la colonne G est alimenté par un cron n8n nocturne qui agrège plusieurs sources publiques (Gitéa Atom, Behold @aep, Behold @julesneny) et écrit un JSON statique servi par Caddy sur `data.trans-former.fr/journal.json`.
+
+```
+n8n cron (3h00 UTC)
+  -> fetch Gitéa Atom + Behold @aep + Behold @julesneny
+  -> normalisation Code Node
+  -> tri desc + top 100
+  -> écrit /home/node/.n8n/journal/journal.json (volume Docker)
+  -> Caddy data.trans-former.fr file_server expose ce fichier
+  -> JournalList.vue fetch côté client (no rebuild Astro requis)
+```
+
+## Sources V1 actives
+
+| Plateforme | Hashtag | URL feed | Statut |
+|---|---|---|---|
+| Gitéa | `#stack` | `https://git.trans-former.fr/jules.atom` | ACTIF |
+| Behold @aep | `#aep-politique` | `https://feeds.behold.so/{PUBLIC_BEHOLD_AEP}` | conditionnel (skip si feed ID absent) |
+| Behold @julesneny | `#peinture` | `https://feeds.behold.so/{PUBLIC_BEHOLD_JULESNENY}` | conditionnel (skip si feed ID absent) |
+
+## Sources skipped (V1 -> V1.5/V2)
+
+| Plateforme | Hashtag | Raison |
+|---|---|---|
+| GitHub.com | `#stack` | username `julesneny` n'existe pas (HTTP 404). Pivot Gitéa pour le MVP. À reconfirmer si Jules a un autre handle GitHub public. |
+| Substack | `#politique` | `transformations.substack.com` est pris par "WoodHorse" (pas Jules). Handle Substack à confirmer avant V1.5. |
+| LinkedIn | `#building-public` | V2 (RSS via service tiers ou scrape) |
+| Castopod | `#podcast` | V2 (Castopod RSS prêt mais hors scope MVP) |
+| Blog `trans-former.fr` | `#manifeste` | V2 (post-PC8 deploy) |

+## Format JSON
+
+```json
+{
+  "generatedAt": "2026-05-09T03:00:00Z",
+  "items": [
+    {
+      "id": "gitea-2026-05-09-pc6",
+      "platform": "gitea",
+      "hashtag": "#stack",
+      "date": "2026-05-09T01:01:00Z",

+      "extrait": "...",

+      "thumbnail": null
+    }
+  ],
+  "counts": { "total": N, "gitea": N, "instagram": N }
+}
+```
+
+## Composant Vue
+
+`src/components/vue/JournalList.vue` :
+- fetch `import.meta.env.PUBLIC_JOURNAL_URL` (défaut `https://data.trans-former.fr/journal.json`)
+- écoute `window.addEventListener('hashtag-filter-change', ...)` émis par ColJournal.astro
+- filtre par hashtag (vide ou tous cochés -> tout afficher ; tous décochés -> rien)
+- tri desc déjà fait côté n8n, le composant respecte l'ordre
+
+Cabling : `src/components/astro/ColJournal.astro` importe et rend `<JournalList client:visible />` dans `#journal-list`.
+
+## Variable d'env
+
+`PUBLIC_JOURNAL_URL=https://data.trans-former.fr/journal.json` (`.env.example`)
+
+Override possible en local pointant vers `/data/journal.json` (mock fourni dans `public/data/journal.json`).
+
+## Setup VPS — étapes (ops, à valider Jules)
+
+### 1. DNS
+
+Dans OVH zone DNS `trans-former.fr` :
+
+```
+data    A    178.104.106.195    TTL 600
+```
+
+Attendre propagation (~5min).
+
+### 2. Volume Docker partagé n8n -> Caddy
+
+Le container n8n monte `vps-kit_n8n_data:/home/node/.n8n`. On va simplement lire un fichier dans ce volume depuis Caddy.
+
+Path source : `/var/lib/docker/volumes/vps-kit_n8n_data/_data/journal/journal.json`
+
+```bash
+ssh vps-hetzner "mkdir -p /var/lib/docker/volumes/vps-kit_n8n_data/_data/journal && \
+  chown 1000:1000 /var/lib/docker/volumes/vps-kit_n8n_data/_data/journal"
+```
+
+### 3. Caddyfile bloc
+
+Ajouter dans le Caddyfile (probablement `/etc/caddy/Caddyfile` ou `/opt/vps-kit/configs/Caddyfile`) :
+
+```caddy
+data.trans-former.fr {
+    root * /var/lib/docker/volumes/vps-kit_n8n_data/_data/journal
+    file_server {
+        index journal.json
+    }
+    encode gzip
+    header {
+        Cache-Control "public, max-age=300"
+        Access-Control-Allow-Origin "https://trans-former.fr"
+    }
+    log {
+        output file /var/log/caddy/data.log
+    }
+}
+```
+
+Backup + reload :
+```bash
+ssh vps-hetzner "cp /etc/caddy/Caddyfile /etc/caddy/Caddyfile.bak.$(date +%Y%m%d-%H%M%S) && \
+  systemctl reload caddy && \
+  systemctl status caddy --no-pager | head -10"
+```
+
+### 4. Workflow n8n
+
+Importer `docs/n8n-workflow-journal-aggregate.json` dans https://automate.trans-former.fr (UI -> Import from file).
+
+Activer le toggle, vérifier le cron (`0 3 * * *`).
+
+Configurer les credentials env n8n si besoin (Behold feed IDs) -> non bloquants si absents (workflow skip).
+
+### 5. Smoke test
+
+```bash
+# Run manuel (UI n8n -> Execute Workflow)
+ssh vps-hetzner "ls -la /var/lib/docker/volumes/vps-kit_n8n_data/_data/journal/"
+curl -sf https://data.trans-former.fr/journal.json | jq '.counts'
+```
+
+## Backlog (hors scope PC6)
+
+- Trigger rebuild Astro Coolify webhook (PC8)
+- Sources V2 : LinkedIn, Castopod, Blog, Substack (post handle confirmé)
+- Storage archivage long-terme (V1 = écrasement quotidien)
+- Real-time updates (V3)

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.	2026-05-09 01:22:01 +02:00
