Why: Uploaded images never reached the model, so a text-only chat model could be asked to read a picture it cannot see. Evidence: go test ./internal/... passed locally before this commit. Image-link rejection is covered by vision package tests. Impact: Current-turn attachments and fetched image links become image input. History keeps a text placeholder. Image turns swap to the configured vision model when the chat model is not in the capable list, and fallbacks are filtered the same way.

Agent-System-Backend
对话系统后端：Go 模块化单体，默认构建为单二进制（go:embed 内嵌前端与嵌入式 SQLite 存储）。组合 Agent-Native / Agent-Squad / Agent-Intent 生态，依赖 agent-system-core 契约。
契约与架构见 Agent-System-Documents 设计方案与架构文档；开发规范见 development-guidelines（Dev 仓 development/guidelines）。本仓为 Agent-System 多仓组合的组成部分。
