+## 1. Divisions转换规则
+
+### 1.1 什么是Divisions
+
+`<divisions>` 是MusicXML中最重要的元素之一，它定义了**每个四分音符包含多少个基本时值单位**。
+
+```xml
+<attributes>
+  <divisions>256</divisions>  <!-- 1个四分音符 = 256个divisions -->
+</attributes>
+```
+
+### 1.2 核心转换公式
+
+```typescript
+/**
+ * 将MusicXML的duration转换为实际时值（以四分音符为单位）
+ * @param duration MusicXML中的duration值
+ * @param divisions 当前小节的divisions值
+ * @returns 实际时值（1.0 = 四分音符）
+ */
+function toRealValue(duration: number, divisions: number): number {
+  return duration / divisions;
+}
+```
+
+### 1.3 常见Divisions值对照表
+
+| divisions值 | 四分音符 | 八分音符 | 十六分音符 | 二分音符 | 全音符 | 附点四分 |
+|------------|---------|---------|-----------|---------|-------|---------|
+| 1 | 1 | 0.5 | 0.25 | 2 | 4 | 1.5 |
+| 256 | 256 | 128 | 64 | 512 | 1024 | 384 |
+| 480 | 480 | 240 | 120 | 960 | 1920 | 720 |
+| 960 | 960 | 480 | 240 | 1920 | 3840 | 1440 |
+
+### 1.4 异常情况处理
+
+| 情况 | 处理方式 | 代码示例 |
+|------|---------|---------|
+| divisions = 0 | 抛出错误 | `throw new Error('divisions不能为0')` |
+| divisions = null/undefined | 使用默认值256 | `divisions = divisions ?? 256` |
+| divisions为负数 | 取绝对值并警告 | `divisions = Math.abs(divisions)` |
+| duration为负数 | 取绝对值并警告 | `duration = Math.abs(duration)` |
+
+### 1.5 实现代码模板
+
+```typescript
+class DivisionsHandler {
+  private currentDivisions: number = 256;
+  
+  /**
+   * 更新当前divisions值
+   */
+  setDivisions(divisions: number): void {
+    if (divisions === 0) {
+      throw new Error('divisions值不能为0');
+    }
+    if (divisions < 0) {
+      console.warn(`divisions为负数(${divisions})，已取绝对值`);
+      divisions = Math.abs(divisions);
+    }
+    this.currentDivisions = divisions;
+  }
+  
+  /**
+   * 转换duration到实际时值
+   */
+  toRealValue(duration: number): number {
+    if (duration < 0) {
+      console.warn(`duration为负数(${duration})，已取绝对值`);
+      duration = Math.abs(duration);
+    }
+    return duration / this.currentDivisions;
+  }
+  
+  /**
+   * 获取当前divisions值
+   */
+  getDivisions(): number {
+    return this.currentDivisions;
+  }
+}
+```
+

+
+## 2. 音高元素解析规则
+
+### 2.1 Pitch元素结构
+
+```xml
+<pitch>
+  <step>C</step>      <!-- 音名：C D E F G A B -->
+  <alter>1</alter>    <!-- 升降：1=升，-1=降，0或不存在=自然 -->
+  <octave>4</octave>  <!-- 八度：通常0-9，4是中央C所在的八度 -->
+</pitch>
+```
+
+### 2.2 Step到简谱数字的映射
+
+| MusicXML Step | 简谱数字 | 唱名 | 说明 |
+|--------------|---------|------|------|
+| C | 1 | do | 基准音 |
+| D | 2 | re | |
+| E | 3 | mi | |
+| F | 4 | fa | |
+| G | 5 | sol | |
+| A | 6 | la | |
+| B | 7 | si | |
+
+**实现代码：**
+```typescript
+const STEP_TO_JIANPU: Record<string, number> = {
+  'C': 1, 'D': 2, 'E': 3, 'F': 4, 'G': 5, 'A': 6, 'B': 7
+};
+
+function stepToJianpu(step: string): number {
+  const pitch = STEP_TO_JIANPU[step.toUpperCase()];
+  if (pitch === undefined) {
+    throw new Error(`无效的音名: ${step}`);
+  }
+  return pitch;
+}
+```
+
+### 2.3 Octave到高低音点的映射
+
+| MusicXML Octave | 八度偏移 | 简谱表示 | 说明 |
+|----------------|---------|---------|------|
+| 2 | -2 | 两个下点 | 低两个八度 |
+| 3 | -1 | 一个下点 | 低一个八度 |
+| 4 | 0 | 无点 | 中音区（基准） |
+| 5 | +1 | 一个上点 | 高一个八度 |
+| 6 | +2 | 两个上点 | 高两个八度 |
+
+**实现代码：**
+```typescript
+const BASE_OCTAVE = 4;  // 中央C所在的八度
+
+function octaveToOffset(octave: number): number {
+  return octave - BASE_OCTAVE;
+}
+
+// 示例
+octaveToOffset(3);  // -1（低音）
+octaveToOffset(4);  // 0（中音）
+octaveToOffset(5);  // +1（高音）
+```
+
+### 2.4 Alter到升降号的映射
+
+| MusicXML Alter | 简谱符号 | 含义 | 类型 |
+|---------------|---------|------|------|
+| 2 | ×（或##） | 重升 | double-sharp |
+| 1 | # | 升半音 | sharp |
+| 0 | ♮ | 还原 | natural |
+| -1 | ♭ | 降半音 | flat |
+| -2 | ♭♭ | 重降 | double-flat |
+| 不存在 | 无 | 自然音 | none |
+
+**实现代码：**
+```typescript
+type Accidental = 'sharp' | 'flat' | 'natural' | 'double-sharp' | 'double-flat' | null;
+
+function alterToAccidental(alter: number | null): Accidental {
+  if (alter === null || alter === undefined) return null;
+  
+  switch (alter) {
+    case 2: return 'double-sharp';
+    case 1: return 'sharp';
+    case 0: return 'natural';
+    case -1: return 'flat';
+    case -2: return 'double-flat';
+    default:
+      console.warn(`未知的alter值: ${alter}`);
+      return null;
+  }
+}
+```
+
+### 2.5 完整音高解析示例
+
+```xml
+<!-- 示例1：中央C -->
+<pitch>
+  <step>C</step>
+  <octave>4</octave>
+</pitch>
+<!-- 结果：pitch=1, octave=0, accidental=null -->
+
+<!-- 示例2：高音升F -->
+<pitch>
+  <step>F</step>
+  <alter>1</alter>
+  <octave>5</octave>
+</pitch>
+<!-- 结果：pitch=4, octave=1, accidental='sharp' -->
+
+<!-- 示例3：低音降B -->
+<pitch>
+  <step>B</step>
+  <alter>-1</alter>
+  <octave>3</octave>
+</pitch>
+<!-- 结果：pitch=7, octave=-1, accidental='flat' -->
+```

+
+## 3. 时值元素解析规则
+
+### 3.1 Type元素（音符类型）
+
+| MusicXML Type | 简谱时值 | 增/减时线 | 说明 |
+|--------------|---------|----------|------|
+| 128th | 0.03125 | 5条减时线 | 一百二十八分音符 |
+| 64th | 0.0625 | 4条减时线 | 六十四分音符 |
+| 32nd | 0.125 | 3条减时线 | 三十二分音符 |
+| 16th | 0.25 | 2条减时线 | 十六分音符 |
+| eighth | 0.5 | 1条减时线 | 八分音符 |
+| quarter | 1.0 | 无 | 四分音符（基准） |
+| half | 2.0 | 1条增时线 | 二分音符 |
+| whole | 4.0 | 3条增时线 | 全音符 |
+| breve | 8.0 | 7条增时线 | 二全音符 |
+
+**实现代码：**
+```typescript
+const TYPE_TO_DURATION: Record<string, number> = {
+  '128th': 0.03125,
+  '64th': 0.0625,
+  '32nd': 0.125,
+  '16th': 0.25,
+  'eighth': 0.5,
+  'quarter': 1.0,
+  'half': 2.0,
+  'whole': 4.0,
+  'breve': 8.0,
+};
+
+function typeToBaseDuration(type: string): number {
+  const duration = TYPE_TO_DURATION[type.toLowerCase()];
+  if (duration === undefined) {
+    console.warn(`未知的音符类型: ${type}，使用四分音符`);
+    return 1.0;
+  }
+  return duration;
+}
+```
+
+### 3.2 Dot元素（附点）
+
+附点会增加原时值的特定比例：
+
+| 附点数量 | 时值倍数 | 计算公式 | 示例（四分音符） |
+|---------|---------|---------|----------------|
+| 0 | 1.0 | base | 1.0 |
+| 1 | 1.5 | base × 1.5 | 1.5 |
+| 2 | 1.75 | base × 1.75 | 1.75 |
+| 3 | 1.875 | base × 1.875 | 1.875 |
+
+**计算公式：**
+```typescript
+/**
+ * 计算附点后的时值
+ * @param baseDuration 基准时值
+ * @param dots 附点数量
+ * @returns 附点后的时值
+ */
+function applyDots(baseDuration: number, dots: number): number {
+  let multiplier = 1.0;
+  let addition = 0.5;
+  
+  for (let i = 0; i < dots; i++) {
+    multiplier += addition;
+    addition /= 2;
+  }
+  
+  return baseDuration * multiplier;
+}
+
+// 示例
+applyDots(1.0, 0);  // 1.0（四分音符）
+applyDots(1.0, 1);  // 1.5（附点四分音符）
+applyDots(1.0, 2);  // 1.75（双附点四分音符）
+applyDots(2.0, 1);  // 3.0（附点二分音符）
+```
+
+### 3.3 Duration元素的验证
+
+**重要：** 我们应该优先使用 `duration / divisions` 计算实际时值，而不是依赖 `type`。`type` 可以用于验证。
+
+```typescript
+/**
+ * 解析并验证时值
+ */
+function parseDuration(
+  duration: number,
+  divisions: number,
+  type: string | null,
+  dots: number
+): { realValue: number; isValid: boolean } {
+  // 从duration计算实际时值
+  const realValue = duration / divisions;
+  
+  // 如果有type，用于验证
+  if (type) {
+    const expectedFromType = applyDots(typeToBaseDuration(type), dots);
+    const tolerance = 0.001;
+    
+    if (Math.abs(realValue - expectedFromType) > tolerance) {
+      console.warn(
+        `时值不一致: duration计算=${realValue}, type计算=${expectedFromType}`
+      );
+    }
+  }
+  
+  return { realValue, isValid: true };
+}
+```
+
+### 3.4 时值到增/减时线的转换
+
+```typescript
+/**
+ * 计算增时线数量
+ * 规则：只有时值 >= 1.0（四分音符及以上）才有增时线
+ * 公式：Math.floor(realValue) - 1
+ */
+function calcExtensionLines(realValue: number): number {
+  if (realValue < 1.0) return 0;
+  return Math.floor(realValue) - 1;
+}
+
+/**
+ * 计算减时线数量
+ * 规则：只有时值 < 1.0（短于四分音符）才有减时线
+ * 公式：Math.round(Math.log2(1 / realValue))
+ */
+function calcUnderlines(realValue: number): number {
+  if (realValue >= 1.0) return 0;
+  return Math.round(Math.log2(1 / realValue));
+}
+
+// 验证表
+// realValue=4.0（全音符）→ 3条增时线
+// realValue=2.0（二分音符）→ 1条增时线
+// realValue=1.5（附点四分音符）→ 0条增时线（有附点）
+// realValue=1.0（四分音符）→ 0条增时线
+// realValue=0.5（八分音符）→ 1条减时线
+// realValue=0.25（十六分音符）→ 2条减时线
+// realValue=0.125（三十二分音符）→ 3条减时线
+```

+  const isGrace = noteElement.querySelector('grace') !== null;
+

+
+**计算说明：**
+```typescript

 ---
 
-**下一步：** 完成任务0.5.2后，开始编写此文档
+## 6. 事件和交互规范
+
+### 6.1 音符点击事件
+
+业务代码通过以下方式处理音符点击：
+
+```typescript
+// 通过state.times查找被点击的音符
+const clickedNote = state.times.find(note => 
+  note.svgElement?.attrs?.id === clickedElementId.replace('vf-', '')
+);
+
+if (clickedNote) {
+  skipNotePlay(clickedNote.i, false, 'manual');
+}
+```
+
+### 6.2 小节选择
+
+```typescript
+// 选段功能使用MeasureNumberXML
+const startNote = state.times.find(n => 
+  n.noteElement.sourceMeasure.MeasureNumberXML === startMeasure
+);
+
+const endNote = state.times.filter(n => 
+  n.noteElement.sourceMeasure.MeasureNumberXML === endMeasure
+).last();
+```
+
+---
+
+## 7. 颜色和样式规范
+
+### 7.1 选中小节背景色
+
+```javascript
+// 播放中的小节
+item.querySelector('.vf-custom-bg')?.setAttribute("fill", "rgba(9,159,255,0.15)");
+
+// 预备小节
+item.querySelector('.vf-custom-bg')?.setAttribute("fill", "rgba(255,193,48,0.15)");
+
+// 未选中小节
+item.querySelector('.vf-custom-bg')?.setAttribute("fill", "transparent");
+```
+
+### 7.2 音符高亮类名
+
+```javascript
+// 添加高亮
+svgEl?.classList.add('noteActive');
+stemEl?.classList.add('noteActive');
+
+// 移除高亮
+svgEl?.classList.remove('noteActive');
+```
+
+---
+
+## 8. 兼容性检查清单
+
+新引擎实现时，需要确保以下兼容性：
+
+### 8.1 必须实现的功能
+
+- [ ] 生成符合规范的state.times数组
+- [ ] 实现cursor.reset()和cursor.next()方法
+- [ ] SVG元素ID遵循 `vf-{id}` 格式
+- [ ] 小节元素包含 `data-num` 属性
+- [ ] 支持 `.noteActive` 等CSS类名切换
+
+### 8.2 必须保留的字段
+
+**关键字段（播放功能）：**
+- `time`, `endtime` - 时间定位
+- `i` - 索引定位
+- `MeasureNumberXML` - 小节定位
+
+**关键字段（评测功能）：**
+- `frequency`, `frequencyList` - 音高检测
+- `halfTone`, `realKey` - 指法显示
+- `duration` - 时值验证
+
+**关键字段（渲染功能）：**
+- `svgElement` - DOM操作
+- `bbox` - 位置计算
+- `noteElement` - 原始数据
+
+---
+
+## 9. 迁移策略
+
+### 9.1 渐进式迁移
+
+1. **第一阶段**：新引擎生成兼容的times数组
+2. **第二阶段**：替换渲染逻辑，保持数据结构不变
+3. **第三阶段**：优化数据结构，提供适配层
+
+### 9.2 适配器模式
+
+```typescript
+class OSMDCompatibilityAdapter {
+  // 将新引擎数据转换为兼容格式
+  generateTimesArray(): CompatibleTimesItem[] {
+    return this.renderer.getAllNotes().map(note => ({
+      i: note.index,
+      id: note.id,
+      time: note.startTime,
+      endtime: note.endTime,
+      // ... 其他兼容字段
+    }));
+  }
+}
+```

+## 2. 音符数字渲染
+
+### 2.1 基本渲染规则
+
+```typescript
+interface NoteRenderSpec {
+  /** 数字内容：1-7 或 0（休止符） */
+  text: string;
+  
+  /** 字体大小 */
+  fontSize: number;
+  
+  /** 字体粗细 */
+  fontWeight: 'normal' | 'bold';
+  
+  /** 水平对齐 */
+  textAnchor: 'middle';
+  
+  /** 垂直对齐基线 */
+  dominantBaseline: 'central';
+}
+```
+
+### 2.2 SVG实现
+
+```typescript
+function drawNoteNumber(
+  x: number,
+  y: number,
+  pitch: number,
+  config: RenderConfig
+): SVGTextElement {
+  const text = document.createElementNS(SVG_NS, 'text');
+  
+  text.setAttribute('x', String(x));
+  text.setAttribute('y', String(y));
+  text.setAttribute('font-size', String(config.noteFontSize));
+  text.setAttribute('font-family', config.noteFont);
+  text.setAttribute('text-anchor', 'middle');
+  text.setAttribute('dominant-baseline', 'central');
+  text.setAttribute('fill', config.noteColor);
+  text.setAttribute('class', 'vf-numbered-note-head');
+  
+  text.textContent = String(pitch);
+  
+  return text;
+}
+```
+
+### 2.3 音符宽度计算
+
+```typescript
+/**
+ * 计算音符显示宽度
+ * 基于时值计算，保证固定时间比例
+ */
+function calculateNoteWidth(realValue: number, quarterSpacing: number): number {
+  return realValue * quarterSpacing;
+}
+
+// 示例：
+// 四分音符(1.0) → 50px
+// 八分音符(0.5) → 25px
+// 二分音符(2.0) → 100px
+// 全音符(4.0) → 200px
+```
+
+---
+
+## 3. 增时线渲染规范
+
+### 3.1 核心规则 ⭐⭐⭐
+
+**增时线是简谱渲染的核心难点！**
+
+```
+增时线规则：
+1. 只有时值 >= 1.0（四分音符及以上）才可能有增时线
+2. 数量 = Math.floor(realValue) - 1
+3. 每条增时线代表1个四分音符的时值
+4. 增时线应该按时值均匀分布在占用的空间中
+```
+
+### 3.2 数量计算
+
+| 音符类型 | 时值(realValue) | 增时线数量 | 视觉表示 |
+|---------|----------------|-----------|---------|
+| 四分音符 | 1.0 | 0 | `5` |
+| 附点四分 | 1.5 | 0 | `5·` |
+| 二分音符 | 2.0 | 1 | `5 —` |
+| 附点二分 | 3.0 | 2 | `5· — —` |
+| 全音符 | 4.0 | 3 | `5 — — —` |
+
+```typescript
+function calcExtensionLineCount(realValue: number): number {
+  if (realValue < 1.0) return 0;
+  return Math.floor(realValue) - 1;
+}
+```
+
+### 3.3 位置计算 ⭐⭐⭐
+
+**关键：增时线要按四分音符间距均匀分布！**
+
+```typescript
+interface ExtensionLinePosition {
+  /** 增时线起始X坐标 */
+  x: number;
+  /** 增时线Y坐标（与音符数字基线平齐） */
+  y: number;
+  /** 增时线长度 */
+  width: number;
+}
+
+/**
+ * 计算增时线位置
+ * @param noteX 音符中心X坐标
+ * @param noteY 音符中心Y坐标
+ * @param lineIndex 增时线索引（0开始）
+ * @param quarterSpacing 四分音符间距
+ */
+function calcExtensionLinePosition(
+  noteX: number,
+  noteY: number,
+  lineIndex: number,
+  quarterSpacing: number
+): ExtensionLinePosition {
+  // 每条增时线占据1个四分音符的空间
+  // 第1条增时线在音符后的第1个四分音符位置
+  // 第2条增时线在音符后的第2个四分音符位置...
+  
+  const lineStartX = noteX + (lineIndex + 1) * quarterSpacing;
+  const lineWidth = quarterSpacing * 0.7;  // 占空间的70%，居中
+  const lineX = lineStartX - lineWidth / 2;
+  
+  return {
+    x: lineX,
+    y: noteY,
+    width: lineWidth,
+  };
+}
+```
+
+### 3.4 视觉示意图
+
+```
+二分音符（2拍）：
+┌─────────┬─────────┐

+└─────────┴─────────┴─────────┴─────────┘
+  音符       增时线1    增时线2    增时线3
+```
+
+### 3.5 增时线样式
+
+```typescript
+function drawExtensionLine(
+  x: number,
+  y: number,
+  width: number,
+  config: RenderConfig
+): SVGRectElement {
+  const line = document.createElementNS(SVG_NS, 'rect');
+  
+  line.setAttribute('x', String(x));
+  line.setAttribute('y', String(y - config.extensionLineHeight / 2));
+  line.setAttribute('width', String(width));
+  line.setAttribute('height', String(config.extensionLineHeight));
+  line.setAttribute('fill', config.lineColor);
+  line.setAttribute('class', 'vf-extension-line');
+  
+  return line;
+}
+```
+
+### 3.6 附点+增时线组合
+
+```
+附点二分音符（3拍）：
+┌───────────────┬─────────┬─────────┐
+│     5·        │    —    │    —    │
+│   1.5拍        │  第2拍   │  第3拍   │
+└───────────────┴─────────┴─────────┘
+  附点四分音符占1.5拍，后面2条增时线各占1拍
+
+计算方式：
+- realValue = 3.0
+- 增时线数量 = Math.floor(3.0) - 1 = 2
+- 第1条增时线位置：noteX + quarterSpacing * 1.5（从附点结束位置开始）
+- 第2条增时线位置：noteX + quarterSpacing * 2.5
+```
+
+### 3.7 多声部场景
+
+```
+多声部时，增时线要与其他声部的音符垂直对齐：
+
+声部1:  5 — — —    (全音符)
+声部2:  1 2 3 4    (四个四分音符)
+        ↑ ↑ ↑ ↑
+        X坐标必须对齐
+
+规则：先进行多声部对齐计算，再绘制增时线
+```
+
+---
+
+## 4. 减时线渲染规范
+
+### 4.1 数量计算
+
+| 音符类型 | 时值(realValue) | 减时线数量 | 视觉表示 |
+|---------|----------------|-----------|---------|
+| 四分音符 | 1.0 | 0 | `5` |
+| 八分音符 | 0.5 | 1 | `5` + 1条线 |
+| 十六分音符 | 0.25 | 2 | `5` + 2条线 |
+| 三十二分音符 | 0.125 | 3 | `5` + 3条线 |
+
+```typescript
+function calcUnderlineCount(realValue: number): number {
+  if (realValue >= 1.0) return 0;
+  return Math.round(Math.log2(1 / realValue));
+}
+```
+
+### 4.2 位置和间距
+
+```typescript
+interface UnderlineSpec {
+  /** 减时线宽度 */
+  width: number;
+  /** 减时线高度（粗细） */
+  height: number;
+  /** 第一条线距离音符底部的距离 */
+  topOffset: number;
+  /** 多条线之间的间距 */
+  gap: number;
+}
+
+const UNDERLINE_SPEC: UnderlineSpec = {
+  width: 16,      // 略宽于数字宽度
+  height: 1.5,    // 线条粗细
+  topOffset: 4,   // 距音符底部4px
+  gap: 3,         // 多条线间距3px
+};
+```
+
+### 4.3 视觉示意图
+
+```
+八分音符（1条减时线）：
+    5
+   ───

+   ───
+
+三十二分音符（3条减时线）：
+    5
+   ───
+   ───
+   ───
+```
+
+### 4.4 SVG实现
+
+```typescript
+function drawUnderlines(
+  noteX: number,
+  noteBottomY: number,
+  count: number,
+  config: RenderConfig
+): SVGGElement {

+    
+    group.appendChild(line);
+  }
+  
+  return group;
+}
+```
+
+### 4.5 连续音符的减时线连接
+
+```
+连续的相同时值音符，减时线应该连接：
+
+分离绘制：          连接绘制（推荐）：
+  1   2   3   4       1   2   3   4
+  _   _   _   _       ─────────────
+
+规则：
+- 同一拍内的连续短音符，减时线连接
+- 跨拍的音符，减时线可以分开
+- 当前实现先使用分离绘制，后续优化为连接绘制
+```
+

+
+## 5. 高低音点规范

+### 5.1 位置规则
+
+```
+高音点：在音符数字上方

+### 10.3 DOM结构要求
+
+```html
+<!-- 歌词元素必须包含以下属性，用于业务层高亮匹配 -->
+<text 
+  class="vf-lyric lyric{noteId}"
+  lyricIndex="1"
+  data-note-id="{noteId}"
+>
+  歌词文字
+</text>
+```
+
+### 10.4 SVG实现
+
+```typescript
+function drawLyric(
+  noteX: number,
+  noteBottomY: number,
+  text: string,
+  lyricIndex: number,
+  noteId: string,
+  config: RenderConfig

+
+## 11. 布局规范
+
+### 11.1 小节宽度计算
+
+```typescript
+/**
+ * 计算小节宽度（固定时间比例）
+ * 公式：(拍数 / 单位拍 × 4) × 四分音符间距 + 左右padding
+ */
+function calculateMeasureWidth(
+  beats: number,
+  beatType: number,
+  quarterSpacing: number,
+  padding: number
+): number {
+  // 小节总时值（以四分音符为单位）
+  const totalBeats = beats / (beatType / 4);
+  
+  // 内容宽度
+  const contentWidth = totalBeats * quarterSpacing;
+  
+  // 总宽度
+  return contentWidth + padding * 2;
+}
+
+// 示例：
+// 4/4拍: (4 / 1) × 50 + 20 × 2 = 240px
+// 3/4拍: (3 / 1) × 50 + 20 × 2 = 190px
+// 6/8拍: (6 / 2) × 50 + 20 × 2 = 190px
+```
+
+### 11.2 音符X坐标计算
+
+```typescript
+/**
+ * 计算音符X坐标（固定时间比例）
+ * 公式：小节X + padding + 时间戳 × 四分音符间距
+ */
+function calculateNoteX(
+  measureX: number,
+  timestamp: number,
+  padding: number,
+  quarterSpacing: number
+): number {
+  return measureX + padding + timestamp * quarterSpacing;
+}
+```
+
+### 11.3 自动换行规则
+
+```typescript
+interface LineBreakSpec {
+  /** 最大行宽 */
+  maxWidth: number;
+  /** 最小小节数/行 */
+  minMeasuresPerLine: number;
+  /** 最大小节数/行 */
+  maxMeasuresPerLine: number;
+}
+
+function calculateLineBreaks(
+  measures: JianpuMeasure[],
+  maxWidth: number
+): number[][] {
+  const lines: number[][] = [];
+  let currentLine: number[] = [];
+  let currentWidth = 0;
+  
+  measures.forEach((measure, index) => {
+    if (currentWidth + measure.width > maxWidth && currentLine.length > 0) {
+      lines.push(currentLine);
+      currentLine = [];
+      currentWidth = 0;
+    }
+    
+    currentLine.push(index);
+    currentWidth += measure.width;
+  });
+  
+  if (currentLine.length > 0) {
+    lines.push(currentLine);
+  }
+  
+  return lines;
+}
+```
+
+### 11.4 多声部Y坐标计算
+
+```typescript
+/**
+ * 计算声部Y坐标
+ */
+function calculateVoiceY(
+  baseY: number,
+  voiceIndex: number,
+  voiceCount: number,
+  voiceSpacing: number
+): number {
+  // 多声部垂直居中分布
+  const totalHeight = (voiceCount - 1) * voiceSpacing;
+  const startY = baseY - totalHeight / 2;
+  
+  return startY + voiceIndex * voiceSpacing;
+}
+```

+## 🛠️ 数据收集方法
+
+### 方法1：使用数据收集工具页面
+
+1. 启动项目开发服务器：`npm run dev`
+2. 打开数据收集页面：`/src/jianpu-renderer/__tests__/collect-baseline.html`
+3. 选择测试文件并点击"渲染"
+4. 点击"导出基准数据"下载数据包
+
+### 方法2：手动收集
+
+1. 在项目中加载测试XML文件
+2. 使用浏览器开发者工具导出数据：
+
+```javascript
+// 在控制台执行以下代码导出 state.times
+copy(JSON.stringify(state.times, null, 2));
+
+// 导出DOM结构
+copy(document.getElementById('osmdSvgPage').outerHTML);
+```
+
+3. 使用浏览器截图功能保存渲染效果

+## 各文件详细说明
+
+### basic.xml (基础简谱测试)
+- **内容**: 只有四分音符的简单旋律
+- **小节数**: 4
+- **拍号**: 4/4
+- **调号**: C大调
+- **速度**: 120 BPM
+- **测试点**:
+  - 四分音符解析
+  - 休止符识别
+  - 高低音点（octave 3-5）
+  - 音高转换（C→1, D→2, ... B→7）
+
+### mixed-durations.xml (混合时值测试)
+- **内容**: 不同时值的音符混合
+- **小节数**: 6
+- **拍号**: 4/4
+- **调号**: C大调
+- **速度**: 100 BPM
+- **测试点**:
+  - 八分音符 → 1条减时线
+  - 十六分音符 → 2条减时线
+  - 二分音符 → 1条增时线
+  - 全音符 → 3条增时线
+  - 附点四分音符 → 数字+附点
+  - 附点二分音符 → 数字+附点+2条增时线
+
+### multi-voice.xml (多声部测试)
+- **内容**: 钢琴双手演奏风格的多声部
+- **小节数**: 4
+- **拍号**: 4/4
+- **调号**: C大调
+- **速度**: 90 BPM
+- **测试点**:
+  - 两个声部的垂直对齐
+  - `<backup>` 元素处理
+  - `<chord>` 和弦处理
+  - 声部1和声部2的独立布局
+  - 休止符在多声部中的对齐
+
+### with-lyrics.xml (带歌词测试)
+- **内容**: 小星星片段，带两遍歌词
+- **小节数**: 4
+- **拍号**: 4/4
+- **调号**: C大调
+- **速度**: 100 BPM
+- **歌词**:
+  - 第1遍: "小星星亮晶晶——满天都是小星——"
+  - 第2遍: "一闪一闪放光明好像那许多小眼睛"
+- **测试点**:
+  - `<lyric number="1">` 第一遍歌词
+  - `<lyric number="2">` 第二遍歌词
+  - 歌词与音符的对应关系
+  - `lyricIndex` 属性生成
+
+### complex.xml (复杂记号测试)
+- **内容**: 包含各种高级音乐记号
+- **小节数**: 6
+- **拍号**: 4/4 → 3/4 (变拍)
+- **调号**: G大调 (1个升号)
+- **速度**: 120 BPM
+- **divisions**: 480 (故意使用不同值测试divisions转换)
+- **测试点**:
+  - 升号 `#` (alter=1)
+  - 降号 `♭` (alter=-1)
+  - 还原号 `♮` (alter=0 + accidental)
+  - 三连音 (`<time-modification>`)
+  - 装饰音 (`<grace>`, duration=0)
+  - 颤音 (`<trill-mark>`)
+  - 顿音 (`<staccato>`)
+  - 重音 (`<accent>`)
+  - 延音线 (`<tie>` + `<tied>`)
+  - 变拍 (4/4 → 3/4)
+  - 力度记号 (pp, mf, ff, crescendo)
+
+## Divisions说明
+
+MusicXML中 `<divisions>` 定义了每个四分音符包含多少个"division"单位：
+
+```
+实际时值 = duration / divisions
+```
+
+示例（divisions=256）:
+- 全音符: duration=1024 → 1024/256 = 4.0
+- 二分音符: duration=512 → 512/256 = 2.0
+- 四分音符: duration=256 → 256/256 = 1.0
+- 八分音符: duration=128 → 128/256 = 0.5
+- 十六分音符: duration=64 → 64/256 = 0.25
+- 附点四分音符: duration=384 → 384/256 = 1.5
+
+示例（divisions=480，用于complex.xml）:
+- 四分音符: duration=480 → 480/480 = 1.0
+- 二分音符: duration=960 → 960/480 = 2.0
+- 八分音符: duration=240 → 240/480 = 0.5
+- 三连音八分: duration=320 → 320/480 ≈ 0.667 (2/3拍)
+
+## 使用方法
+
+```typescript
+// 在测试中加载XML文件
+import { readFileSync } from 'fs';
+import { join } from 'path';
+
+const xmlPath = join(__dirname, 'fixtures', 'basic.xml');
+const xmlContent = readFileSync(xmlPath, 'utf-8');
+
+// 使用JianpuRenderer解析和渲染
+const renderer = new JianpuRenderer(container);
+await renderer.load(xmlContent);
+renderer.render();
+```
+
+## 预期渲染结果
+

  * @description 确保多声部在相同时间点垂直对齐
+ * 
+ * 核心功能：
+ * 1. 收集所有声部的时间戳
+ * 2. 为相同时间戳的音符分配统一的X坐标
+ * 3. 处理边界情况（单声部、休止符、不同时值）
+ * 
+ * 对齐原则：
+ * - 相同时间戳的音符必须垂直对齐（X坐标相同）
+ * - 取所有声部中该时间戳音符的最大X坐标作为统一坐标
+ * - 如果某声部在该时间戳没有音符，不影响其他声部

+
+## 🔧 核心概念
+
+### 1. 数据流
+
+```
+MusicXML/OSMD对象
+      ↓
+  [OSMDDataParser]  解析
+      ↓
+  JianpuScore数据模型
+      ↓
+  [MeasureLayoutEngine]  布局计算
+      ↓
+  带位置信息的JianpuScore
+      ↓
+  [NoteDrawer/LineDrawer/...]  绘制
+      ↓
+  SVG DOM
+      ↓
+  [OSMDCompatibilityAdapter]  生成兼容数据
+      ↓
+  state.times数组（供业务层使用）
+```
+
+### 2. 时值单位
+
+**重要：** 整个系统使用**四分音符为单位**来表示时值。
+
+| 音符类型 | 时值(realValue) | 增时线数 | 减时线数 |
+|---------|----------------|---------|---------|
+| 全音符 | 4.0 | 3 | 0 |
+| 二分音符 | 2.0 | 1 | 0 |
+| 四分音符 | 1.0 | 0 | 0 |
+| 八分音符 | 0.5 | 0 | 1 |
+| 十六分音符 | 0.25 | 0 | 2 |
+| 三十二分音符 | 0.125 | 0 | 3 |
+
+**增时线计算：** `Math.floor(realValue) - 1`（当 realValue >= 1）  
+**减时线计算：** `Math.round(Math.log2(1 / realValue))`（当 realValue < 1）
+
+### 3. Divisions 转换
+
+MusicXML中的duration需要通过divisions转换：
+
+```typescript
+// 实际时值 = duration / divisions
+const realValue = duration / divisions;
+
+// 示例（divisions=256）：
+// 四分音符：256 / 256 = 1.0
+// 八分音符：128 / 256 = 0.5
+// 二分音符：512 / 256 = 2.0
+```
+
+### 4. 音高转换
+
+```typescript
+// 音名到简谱数字的映射
+const NOTE_TO_JIANPU = {
+  'C': 1, 'D': 2, 'E': 3, 'F': 4, 'G': 5, 'A': 6, 'B': 7
+};
+
+// 八度偏移 = MusicXML octave - 4
+// octave=3 → 低音（点在下方）
+// octave=4 → 中音（无点）
+// octave=5 → 高音（点在上方）
+```
+
+---
+
+## 📝 编码规范
+
+### TypeScript规范
+
+1. **使用严格类型**：避免使用 `any`，尽量使用具体类型
+2. **接口优先**：使用 `interface` 定义数据结构
+3. **注释完整**：每个公共方法和属性都要有JSDoc注释
+4. **命名规范**：
+   - 类名：`PascalCase` (如 `NoteDrawer`)
+   - 方法名：`camelCase` (如 `calculateWidth`)
+   - 常量：`UPPER_SNAKE_CASE` (如 `DEFAULT_SPACING`)
+   - 文件名：`PascalCase` 或 `camelCase`
+
+### 代码示例
+
+```typescript
+/**
+ * 计算音符的X坐标
+ * @param timestamp 音符在小节中的时间戳（以四分音符为单位）
+ * @param measureX 小节起始X坐标
+ * @param config 渲染配置
+ * @returns X坐标（像素）
+ */
+function calculateNoteX(
+  timestamp: number,
+  measureX: number,
+  config: RenderConfig
+): number {
+  const { measurePadding, quarterNoteSpacing } = config;
+  return measureX + measurePadding + timestamp * quarterNoteSpacing;
+}
+```
+
+### Git提交规范
+
+```bash
+# 格式：[任务编号] 描述
+
+# 示例：
+git commit -m "[任务1.1] 实现OSMDDataParser基础解析功能"
+git commit -m "[任务2.1] 完成小节布局计算器"
+git commit -m "[修复] 修复增时线位置计算错误"
+git commit -m "[文档] 更新API文档"

+import { createDefaultNote } from '../models';
+
+describe('NoteDrawer', () => {
+  describe('drawNote()', () => {
+    it('应该正确绘制四分音符', () => {
+      const note = createDefaultNote({ pitch: 1, duration: 1 });
+      const svg = drawer.drawNote(note);
+      
+      expect(svg).toBeDefined();
+      expect(svg.querySelector('.note-number')?.textContent).toBe('1');
+    });
+    
+    it('应该为八分音符绘制1条减时线', () => {
+      const note = createDefaultNote({ pitch: 5, duration: 0.5 });
+      const svg = drawer.drawNote(note);
+      
+      const underlines = svg.querySelectorAll('.underline');
+      expect(underlines.length).toBe(1);
+    });
+  });
+});
+```
+
+### 对比测试页面
+
+打开 `__tests__/compare.html` 可以进行可视化对比测试：
+
+1. 选择测试XML文件
+2. 点击"渲染对比"
+3. 左侧显示旧引擎（OSMD）渲染结果
+4. 右侧显示新引擎渲染结果
+5. 点击"差异分析"查看具体差异
+
+---
+
+## 🚨 常见问题
+
+### Q1: divisions不同导致时值计算错误
+
+**问题：** 不同的MusicXML文件有不同的divisions值
+
+**解决方案：**
+```typescript
+// ❌ 错误：直接判断duration
+if (duration === 256) { /* 四分音符 */ }
+
+// ✅ 正确：先转换为相对时值
+const realValue = duration / divisions;
+if (realValue === 1.0) { /* 四分音符 */ }
+```
+
+### Q2: 增时线位置不正确
+
+**问题：** 增时线应该按四分音符间距均匀分布
+
+**解决方案：**
+```typescript
+// 二分音符（2拍）的增时线应该在第2拍的位置
+const extensionLineX = noteX + quarterNoteSpacing;
+
+// 全音符（4拍）的3条增时线
+for (let i = 1; i <= 3; i++) {
+  const lineX = noteX + i * quarterNoteSpacing;
+  drawExtensionLine(lineX);
+}
+```
+
+### Q3: 多声部对齐问题
+
+**问题：** 同一时间点的不同声部音符X坐标不一致
+
+**解决方案：**
+使用 `MultiVoiceAligner` 统一分配X坐标：
+```typescript
+// 收集所有时间戳
+const timestamps = collectAllTimestamps(measure);
+
+// 为每个时间戳分配唯一的X坐标
+const timestampToX = new Map<number, number>();
+timestamps.forEach((ts, index) => {
+  timestampToX.set(ts, calculateX(ts));
+});
+
+// 更新所有声部的音符X坐标
+measure.voices.forEach(voice => {
+  voice.forEach(note => {
+    note.x = timestampToX.get(note.timestamp)!;
+  });
+});
+```
