+La vision native Cursor utilise `SelectedImage` (plafond JPEG souple + `blobIdWithData`) pour les modèles
+qui voient les images nativement — Claude, Gemini, GPT, Kimi et Grok notamment — à partir des images

+`[image attached]` ; les images distantes ou indécodables deviennent des marqueurs d’omission.
+Auto, la famille Composer et GLM (`glm-5.2`, `glm-5.3`) restent
+sur la liste curatée `noVisionModels` et passent par le sidecar de description d'images.

+### Vision
+
+Native Cursor vision uses `SelectedImage` (JPEG soft-cap + `blobIdWithData`) for models that can
+see images natively — Claude, Gemini, GPT, Kimi, and Grok among them — using active-turn `data:`
+images only. Earlier-turn images replay as `[image attached]` text markers; remote or undecodable
+images become omission markers. Auto, the Composer family, and GLM (`glm-5.2`, `glm-5.3`) stay on
+the curated `noVisionModels` list and use the vision describe sidecar instead.
