Academic Slide Minimalist

Non-Bypassable Execution Gates

These gates override every other workflow section in this skill. Run them before any slide-generation or PPTX-packaging action.

Gate A: Image2 availability gate

Before creating final slide images, sample redesigned pages, or a PPTX, explicitly determine whether the current environment has an Image2-style native full-slide image-generation backend.

The backend counts as available only if all are true:

• it can generate one complete 16:9 academic slide image per page;
• the full-slide image can include title, navigation, real source figure crops, annotations, labels, notes, and page number inside the image;
• it can preserve scientific source crops faithfully without redrawing, restyling, or semantically changing them;
• its outputs can be saved as accepted final slide images and then mechanically packaged into an image-only PPTX.

If availability is unavailable, unclear, unconfirmed, or blocked by the current environment, do not create or deliver an Image2-only PPTX. First explain the boundary, then ask whether the user accepts a lower-fidelity fallback PPTX route. Until the user explicitly accepts that fallback, deliver only the valid non-image artifacts: paper reading outputs, adaptive navigation, deck_order_map.md, figure_source_manifest.md, page_briefs.md, Image2 prompts, and assembly notes.

Use this boundary statement when Image2 is unavailable:

当前环境未确认可用 Image2-style 全页幻灯片生成后端，因此无法交付严格 Image2-only 高保真 PPTX。请选择：
A. 只交付可用于后续 Image2 生成的页面方案、figure manifest、page briefs、prompts 与 assembly notes；
B. 接受降级版 PPTX：使用现有 `assets/sample-literature-report.pptx` 的模板、版式节奏和红黑灰学术风格生成可编辑 fallback PPTX；它不是 Image2-only 高保真交付，也不能声称通过 Image2 manifest 与 image-only 验证。

Gate B: Image2 manifest gate

Do not package a PPTX unless image2_manifest.json exists and records every final slide image. The manifest must include:

{
  "image2_backend_confirmed": true,
  "slides": [
    {
      "slide_no": 1,
      "final_image": "final_images/slide_001.png",
      "generation_route": "image2_full_slide",
      "accepted": true,
      "source_figures": []
    }
  ]
}
