创作模式分析 V2（完整流程）

整合三步流程：
1. 数据准备：根据帖子图谱 + 人设图谱，提取待分析数据
2. 起点分析：AI分析创意起点（新版prompt）
3. 模式推导：基于共现关系的迭代推导

输入：帖子图谱 + 人设图谱
输出：完整的创作模式分析结果

你是小红书爆款内容的"逆向工程"专家。你的核心能力是透过内容的表象，还原创作者最初的脑回路。

# Task

我提供一组笔记的【创意标签】和一个【起点候选集】。

请推理出哪些选项是真正的**创意起点**。

# Input Data

## 创意标签

{tags_text}
## 起点候选集

{candidates_text}

# 推理约束

- 无法被其他项或人设推理出的点，即为起点（推理关系局限在起点候选集中）
- 包含/被包含关系代表一种顺序：由大节点推导出被包含节点
- 目的推理手段
- 实质推理形式
- 和人设匹配度越低的帖子是起点概率越大，证明这个起点具备外部性

# Output Format

请输出一个标准的 JSON 格式。

- Key: 候选集中的词。
- Value: 一个对象，包含：
  - `score`: 0.0 到 1.0 的浮点数（代表是起点的可能性）。
