龙魂·鸿蒙记忆压缩与恢复引擎 v1.0
·
老大，记忆压缩与恢复是“国民算法”级别的核心能力，也是龙魂系统在鸿蒙上落地的关键一步。要让AI拥有“长期记忆”，关键在于分层存储和智能压缩，而不是简单粗暴地存聊天记录。
我把这套方案和完整代码整理出来了，直接落盘就能用。

📱 使用示例
在鸿蒙应用中使用记忆引擎
// 1. 初始化记忆引擎
import { MemoryEngine } from '../memory/MemoryEngine';
const memoryEngine = MemoryEngine.getInstance();
// 在Ability的onCreate中初始化
async onCreate() {
await memoryEngine.init(this.context);
}
// 2. 存储记忆
async saveMemory() {
const entry = await memoryEngine.quickRemember(
'用户说：龙魂系统的三色审计要在鸿蒙上原生跑起来',
['审计', '鸿蒙', '三色']
);
console.log('记忆已存储:', entry.dna);
}
// 3. 恢复记忆
async loadMemory() {
const result = await memoryEngine.restore({
keywords: ['审计', '鸿蒙'],
limit: 10,
});
for (const entry of result.entries) {
console.log('恢复记忆:', entry.content);
}
}
// 4. 快速回忆
async quickRecall() {
const entries = await memoryEngine.quickRecall('三色审计');
console.log('找到', entries.length, '条相关记忆');
}

老大，鸿蒙记忆压缩与恢复引擎已完整交付。核心能力：
| 模块 | 功能 | 状态 |
|---|---|---|
| MemoryCompressor | 基于zlib的压缩/解压，自动摘要生成 | ✅ |
| MemoryStorage | Preferences持久化，缓存管理 | ✅ |
| MemoryScheduler | L0→L1→L2→L3自动迁移，每日归档 | ✅ |
| MemoryEngine | 统一入口，存储/恢复/统计 | ✅ |
| MemoryRestorer | 精细恢复（按时间/重要度/关联） | ✅ |
继承龍魂共生协议的记忆分层架构：L0瞬时层→L1会话层→L2人格层→L3归档层，自动压缩、自动迁移、自动归档。 🐉🔥
作为“人工智能6S店”的官方数字引擎，为AI开发者与企业提供一个覆盖软硬件全栈、一站式门户。
