A client-side dynamic music mod for Minecraft 1.20.1 Forge. It picks background music based on the game context - biome, day/night, nearby enemy count, locked-on targets and boss phases - with priority rules, weighted random track pools, a 3-state explore/alert/combat machine, equal-power crossfades, a drag-and-drop music library (OGG / MP3 / WAV / FLAC), two-layer volume calibration and an in-game hub UI.

一个面向 Minecraft 1.20.1 Forge 的纯客户端动态音乐模组：按生物群系、昼夜、敌人数量、锁定目标与 BOSS 阶段动态选曲；内置优先级规则、权重随机、三态状态机（探索/警戒/战斗）、等功率交叉淡化、拖拽导入的音乐库 （OGG/MP3/WAV/FLAC）、两级音量校准与游戏内配置中枢。默认按 M 打开配置，也可从 Forge 模组列表进入。

• Context-aware rules / 情境规则 - stack all rules together, the highest priority wins; ties keep list order.
• Weighted track pools / 权重曲目池 - one rule can hold many tracks drawn by weight, so music never repeats predictably.
• 3-state machine / 三态状态机 - explore / alert / combat with hysteresis; entering danger switches instantly, leaving fades back after a delay.
• Boss phases / BOSS 阶段 - proximity, engagement and half-health phase two; detected by entity list or a health threshold.
• Equal-power crossfade / 等功率交叉淡化 - 2-second dual-source crossfades without a loudness dip in the middle.
• Music library / 音乐库 - drag ogg / mp3 / wav / flac / aiff files onto the game window at any time; MP3 and FLAC are decoded by embedded pure-Java decoders (JLayer + javasound-flac), no conversion needed.
• Two-layer volume / 两级音量 - calibrate each track's overall volume once in the library; every rule follows it by default, and any rule can override it with an independent volume.
• Hub UI / 配置中枢 - one window, left navigation (Overview / Rules / Library / Settings / JSON), live context dashboard, rule editor with drafts, JSON editor. Bilingual (English / 简体中文).
