+# Extension 16 avril 2026 (23h42) — 5 intents top-IA V4
+
+## Intents ajoutés (nl-priority)
+- top_ia_cot_tree → cot_tree.sh (Tree-of-Thought 3 branches + synthesis NVIDIA)
+- top_ia_prefix_cache → prefix_cache.sh (Redis SETEX 3600 TTL)
+- top_ia_image_gen → sdxl_generate.sh (Pollinations FLUX gratuit)
+- top_ia_plugins → plugin_store.sh (list/install/info /opt/weval-plugins/)
+- top_ia_anonymize → anonymize_log.sh (emails/phones/IPs → SHA256 hash)
+
+## Validation E2E chat
+5/5 matchent. cot_tree, prefix_cache, plugins, anonymize = exec réelle OK.
+image_gen = mécanisme OK, Pollinations rate-limit session (retry OK hors pic).
+
+## Découverte technique
+HF Inference API a retiré SDXL/FLUX/SD3 gratuits (404 sur tous).
+Fallback: Pollinations.ai (endpoint public sans clé, FLUX inclus).
+
+## Feuille de route couverte (V4)
+J+15:
+- CoT avancé ✅ (Tree-of-Thought 3 branches)
+J+30:
+- Génération d'images ✅ (Pollinations FLUX)
+J+45:
+- Prefix caching Redis ✅
+- GPU quotas monitor ✅ (V3)
+J+60:
+- Plugin Store ✅
+- Webhooks sortants ✅ (V3)
+J+90:
+- Audit trail ✅ (V3)
+- Anonymisation logs ✅
+- Droit à l'oubli ✅ (V3)
+
+## Total
+25 intents top_ia_ nl-priority (was 20).
+54 intents total opus-intents.php (was 49).
+20 scripts /opt/weval-ops/top-ia/.
