### 翻译条目对齐(审查 R05)
|
||||||
|
|
||||||
|
`llm-translate` 经 `nodes/srt.py` 按 cue 解析(支持 BOM/CRLF、多行、空正文),
|
||||||
|
以全局位置 ID 的 JSON `{id,text}` 数组请求翻译;时间戳不进入模型。返回的 ID
|
||||||
|
集合、类型、唯一性和非空正文必须校验通过,乱序结果按 ID 回填。结构错误最多
|
||||||
|
尝试 3 次,耗尽返回 failed,不再在末尾合并或补空。空 cue 不调模型但保留时间轴;
|
||||||
|
原有长时幻觉清洗继续生效。短句真实 LLM 校准见翻译对齐测试。
|
||||||
|
|
||||||
|
### OCR 空帧与故障恢复(审查 R06)
|
||||||
|
|
||||||
|
相同字幕只合并相邻帧,空帧结束当前段。OCR 临时失败/异常不进入成功存档,
|
||||||
|
失败帧降并发后重试一轮,仍失败则节点 failed,成功帧保留供恢复。JSONL 新增
|
||||||
|
`status=completed`(含成功空文字)或 `skipped`(超长输出按既有规则跳过)。
|
||||||
|
旧存档非空结果复用;无状态的旧空串可能由超时产生,重新识别一次。全量 14236
|
||||||
|
帧回归以真实单线程新结果 1942 条为基线,原 1666 条历史文件保留供比对,
|
||||||
|
新增逐帧覆盖检查防止跨空白合并,不再要求与旧错误时间轴逐字节一致。

"""R05 回归:合法 SRT 多行/空 cue、稳定 ID 翻译和非法模型输出重试。
|
||||||
|
|
||||||
背景:真实任务 run_51242078d76e(CJOD-255-长视频)产出的中文字幕存在
|
历史 run_51242078d76e 出现文本贴错时间;仅检查行数或在末尾合并/补空无法
|
||||||
"内容-时间错位"——例如第 756 条「好像喜欢害羞的样子」被贴到 3805.34s
|
定位中间缺失。本测试在 HTTP 边界注入 JSON 响应,调用真实翻译实现。
|
||||||
(该时间实际是日文「4つんばんですか(趴着吗)」的位置),而这条译文本应是
|
|
||||||
第 758 条「恥ずかしいのが好きみたいなので(喜欢害羞姿势)」的译文。
|
|
||||||
|
|
||||||
根因:nodes/llm.py 的 translate_lines 按 CHUNK_SIZE=20 分批把日文行发给
|
|
||||||
LLM,返回的译文行用 translated.extend() **无条件顺序拼接**,全批结束后只在
|
|
||||||
invoke 末尾做"多截断、少补空"。只要某批 LLM 返回行数 != 输入行数(实测大量
|
|
||||||
批次出现译文 21 行/原文 20 行),该批之后**所有字幕文本整体错位**,而时间戳
|
|
||||||
(从原文复制)保持不变 —— 造成"文本对错时间,程序从时间戳上看不出问题"。
|
|
||||||
|
|
||||||
修复(见 nodes/llm.py):
|
|
||||||
1. 系统提示词新增"逐行独立翻译 + 碎片句按语境给含义 + 禁止合并/拆分",
|
|
||||||
从源头减少 LLM 重组断句导致的行数不一致;
|
|
||||||
2. 程序侧兜底 _repair_batch:返回行数 != 输入行数时,
|
|
||||||
- 多行:末尾多余行合并到前一行(碎片本质同一句,时间轴保留);
|
|
||||||
- 少行:末尾补空串占位(宁缺勿错位,不挤占相邻字幕时间轴)。
|
|
||||||
|
|
||||||
本测试分两层:
|
|
||||||
1. _repair_batch / translate_lines 确定性单元测试(红 -> 绿);
|
|
||||||
2. 真实数据 + 真实 LLM 集成测试(非 mock),验证产物与原文逐条对齐。
