双角色开源项目科普短视频
在双角色开源项目科普骨架上，强制加入 GitHub 浏览录屏和 WorkBuddy 原生窗口录屏，并记录完整来源、采集时间、视口、哈希与隐私检查。
# 双角色开源项目科普短视频 同一固定数字人身份分饰小白与专家，以观众痛点、开源项目方案、真实结果、优势亮点、可信信号和一次追问交付构成 12–25 秒的短版，或 40–50 秒的完整项目讲解；角色对白默认由 AutoDL.Art H3 原生音频与口型同步生成（`minimax_h3_lightx2v_v5`）并逐句过 whisper ASR 验收，官方项目素材默认真实抓取优先（GitHub 页面截图与滚动录屏 → api.github.com 原始素材，本地合成兜底）。 # Entry * [Capsule Card](CARD.md) - Routing summary, purpose, and usage boundary. # Contracts * [Input Schema](contracts/input_schema.yaml) - User input requirements and intake fields. * [Content Scope](contracts/content_scope.yaml) - Series-fixed elements, per-episode content, and forbidden reusable literals. * [Runtime Contract](contracts/runtime.yaml) - Tool roles, execution constraints, and output contract. * [Production Contract](contracts/production_contract.yaml) - Required outputs, evidence floor, and modality gates. # Recipes * [Structure](recipes/structure.md) - Story beats, pacing, and scene architecture. * [Copy](recipes/copy.md) - Voiceover, subtitles, titles, cover copy, lyrics, and CTA rules. * [Visual](recipes/visual.md) - Visua
