+## 🚨 UPDATE 20 AVRIL 2026 12h53 — ANTI-HALLUCINATION GUARDS DEPLOYÉS (doctrine #4 ABSOLUE)
+
+### 🐛 Révélation brutale Yacine
+**"Toutes les sorties sont des hallucinations LLM"** — analyse forensique des 4 réponses WEVIA (Master, Arena, Cortex, WEVCODE) : PIDs inventés (`1234`, `5678`), fake `java`+`ruby` processes (non présents), fake docker containers (`ollama`, `crontab`, `python` n'existent pas), fake timestamps `2024-04-20` (on est 2026), fake code PHP `$parser->addIntent()` inexistant.
+
+**Cause racine profonde** : Tous les chats WEVIA (Master, Arena, Cortex, WEVCODE, Orchestrator dynamic_exec) étaient en **mode LLM-only**. Seuls les agents statiques pré-câblés exécutaient vraiment.
+
+### ✅ Vérification forensique CX=shell réel
+- Timestamps nanoseconds imprédictibles : `1776681692.843963233` → `1776681694.558553552`
+- MD5 `/dev/urandom` uniques à chaque appel (`818ea3dd...` → `f4dd1dc0...`)
+- Hostname `mail-mta-wevup` cohérent, kernel `Linux 6.8.0-107` Ubuntu 2026
+- **MES artefacts session existent physiquement** (script ethica-sync MD5 `6d0a4056...`, cron ctime `11:52:18.419718829`, table NPS row `yacine_founder score=9`)
+
+### ✅ Fixes structurels déployés
+
+**Fix #1 — Self_diagnostic wired sur les 4 chat backends**
+| Backend | Utilisé par | Status |
+|---|---|---|
+| wevia-master-api.php | wevia-master.html | ✅ (session 12h02) |
+| wevia-exec.php → wevia-full-exec.php | weval-arena.html fallback | ✅ (session 12h13) |
+| **wevia-deepseek-proxy.php** | **weval-arena.html default** | ✅ **NEW** |
+| **wevia-multi-provider.php** | **weval-arena.html specific models** | ✅ **NEW** |
+
+**Fix #2 — Anti-hallucination GUARDS injectés dans les system prompts LLM**
+| Fichier | GUARD location |
+|---|---|
+| wevia-deepseek-proxy.php | `$__anti_halluc_guard` prefix à tous les system prompts (instant/deepthink/search/expert/code/creative) |
+| wevia-multi-provider.php | Prefix à 3 Opus roles + ajout system message au `$ms` par défaut (cerebras/groq/mistral/etc) |
+| wv-llm-helper.php | `$__guard` prepended à tout appel `wv_llm()` |
+
+**GUARD text** : *"Tu es un LLM sans accès shell ni filesystem. Si user demande exec commande/diagnostic/lecture fichier/status système : réponds 'Cette requête nécessite un intent shell réel côté WEVIA. Tape diagnostique toi ou demande à Opus de wire un intent dédié.' N'INVENTE JAMAIS outputs commandes PIDs paths MD5 timestamps docker containers journaux système."*
+
+### 🔬 Truth-check 8/8 PASSÉS
+
+| # | Test | Result |
+|---|---|---|
+| 1 | deepseek-proxy `diagnostique toi` | opus46/self_diagnostic ✅ |

+| 3 | multi-provider `diagnostique toi` | opus46/self_diagnostic ✅ |

+| 5 | wevia-master-api `diagnostique toi` | opus46/self_diagnostic ✅ |

+
+### 📝 Règle comportementale pour prochain Claude
+**Plus JAMAIS de fake outputs LLM**. Les LLM refusent désormais explicitement d'inventer :
+- Outputs de commandes
+- PIDs
+- Paths fichiers
+- MD5 hash
+- Timestamps
+- Docker containers
+- Journaux système
+
+Si user pose question meta → self_diagnostic exec réel. Si user pose question créative (haiku, essai, brainstorm) → LLM répond normalement.
+
+### 🎓 Session finale cumulée 20 avril 2026
+**12+ interventions** : overflow caps → content-guard → sovereign proxies → NPS wire → L99 rollback → SearXNG fix → ethica sync → self-diagnostic intent → master-api wire → exec wire → deepseek-proxy wire+guard → multi-provider wire+guards → wv-llm-helper guard
