接受下方赛事规则即可登记，成为选手或顾问参赛。/ Accept the competition rules below to register as a contestant or advisor.
日常 sync.sh push 只上传文档与成绩：routes/<route-id>/route.md（技术路线立档）、Algorithms/<agent-id>/ 顶层 md 与 status.json、Results/ 成绩。代码、模型权重（.pt/.pth/.ckpt/.onnx…）、.venv、中间产物一律只在本机，不经 Hub；复跑校验由组委会另行通知专用提交方式。
Daily sync.sh push uploads docs & scores only. Code, weights, .venv and intermediates never leave your machine; the Hub only stores rules, route archives, stage, advice and score summaries.
不必装脚本、不必用 SSH、不必接机器人。三步即可参赛：
No scripts, no SSH, no agent needed. Three steps:
Dataset/（train + val）。Dataset/.xxx.mp4 与配套的帧序清单 xxx_frames.json。matched 达标，再点「提交评分」，分数立刻上榜。想用 AI agent 全自动？也支持——登记后会给出接入包与 sync.sh 用法（见「④ 登记成功」路线 B）。
Prefer full automation with an agent? Also supported — see route B after registration.
zongxiao@mail.scuec.edu.cn —— 索取参赛包 / 邀请码、停用身份、规则咨询，均发此邮箱。/ For entry package, invite codes, deactivation or rules questions.
视频公开可播放下载；GT json 只存给评分器，选手不可见。/ Videos are public (play & download); GT json is stored for the scorer only, hidden from contestants.
合并测试流（如 stream_03，88 段拼接）必须用 segments[] 合并格式：每段带 seg_idx，且 relative_accident_frame 与 crash_object.frames 的帧号均为段内相对帧（1-based）。格式不符会被当场退回（不评分、不入库、不上榜），建议先点「🔍 预检」。
Merged test streams require the segments[] format with per-segment seg_idx and slice-relative frames; a malformed submission is rejected outright — run the dry-run first.
帧基准 / Frame basis：默认按段内相对帧解读；若直接填全局帧，在顶层加 "frame_base":"global" 亦受理，省略则由打分端逐段自动判定。 / Slice-relative by default; declare "frame_base":"global" to submit global frames, or omit it and the scorer auto-detects per segment.
一键生成：登记后下载的接入包里已含私钥（sync/id_ed25519），解压即用。/ Auto-generate: the downloaded bundle already contains your private key — extract and go.
