TASK 79 · TRACEABLE DERIVED V2V DEMO · 2026-07-21

消费品装配步骤乱序重排

两组 Demo 均来自已审计的 Assembly101 Raw，但与 Dataset Report 展示的 c03d / c10c 完全不同。Input 把同一条 recording 中的 5 个官方 fine-action clips 固定打乱；Target 只把这 5 个相同编码 clips 恢复到原时间顺序。

③ Prompt

Reorder the five atomic assembly clips into the correct chronological order. Output only the reordered video, preserving every clip exactly once.

Demo / Raw boundary

Publisher-native：continuous source MP4、fine-action IDs、labels、frame bounds、recording/view keys。
Derived demo：原子切片、固定 permutation、Input/Target 拼接、Prompt、Metadata、浏览器转码。Assembly101 并未发布乱序/正序视频 pair；这些文件不属于 Raw。

Canonical provenance：task79_demo_manifest.json

Recommended evaluation：exact permutation accuracy、Kendall’s τ、pairwise precedence accuracy、normalized edit distance；按 N 和是否含 attempt/correction 干扰分别报告。
