+## 1.115.4 - 2026-05-11
+
+### Documentation
+- Image generation backend selection: emphasize Codex `imagegen` as the priority runtime-native tool (invoke via the `Skill` tool with `skill: "imagegen"`) and forbid SVG/HTML/canvas substitution when no raster backend can be resolved — fall through to asking the user instead of silently emitting code-based art. Updated in `docs/image-generation-tools.md` and inlined into `baoyu-article-illustrator`, `baoyu-comic`, `baoyu-cover-image`, `baoyu-image-cards`, `baoyu-infographic`, `baoyu-slide-deck`, and `baoyu-xhs-images`.

+### 文档
+- 图片生成后端选择规则强化：明确将 Codex `imagegen` 作为运行时原生工具的优先项（通过 `Skill` 工具调用，`skill: "imagegen"`），并禁止在无可用光栅后端时降级为 SVG/HTML/canvas 等代码渲染 —— 应退回到询问用户，而非静默输出代码绘图。规则同步更新到 `docs/image-generation-tools.md`，并按自包含规则内联到 `baoyu-article-illustrator`、`baoyu-comic`、`baoyu-cover-image`、`baoyu-image-cards`、`baoyu-infographic`、`baoyu-slide-deck`、`baoyu-xhs-images`。
