# code-tape Subtitle Postprocessor LoRA v12

LoRA adapter for the code-tape browser-local subtitle postprocessor. It is trained to correct ASR subtitles for frontend/code terminology and generate playback chapter jump points.

## Contract

Input messages contain:

- `context`: file name, code/runtime snippets, and glossary.
- `inputSegments`: subtitle `id` and `text` only.
- `timeline`: subtitle `id`, `startMs`, and `endMs`.

Output must be one JSON object:

```json
{"segments":[{"id":"subtitle-1","text":"这里用 useState 维护 count"}],"chapters":[{"title":"状态设计","startMs":0,"endMs":1000}]}
```

`segments` should be sparse and contain only changed subtitles.
