# 从 transcript 出发，检查每个句子是否需要删除
for sentence in transcript['sentences']:
    if normalize(sentence['text']) in 审查稿删除标记:
        删除这个句子

1. Load the review draft and extract all ~~deletion markers~~
    ↓
2. Load transcript.json (sentence-level timestamps)
    ↓
3. Iterate through each sentence and check if it is in the deletion markers
    ↓
4. Merge consecutive deletions → Calculate retained segments
    ↓
5. Generate FFmpeg filter → Execute clipping
    ↓
6. Output podcast_v2.mp3/mp4

def is_sentence_deleted(sentence_text, deletions):
    """检查句子是否应该删除"""
    text_norm = normalize(sentence_text)  # 移除空格标点

    # 句子出现在任一删除标记中 → 删除
    for deletion in deletions:
        if text_norm in normalize(deletion):
            return True

    return False
