逐步思考，无限进化。 Step by Step, Infinite Evolution.
Every AI conversation starts from zero. Knowledge accumulated in one session vanishes before the next.
每次 AI 对话都从零开始。上一次积累的知识，下一次全部消失。
This is not a feature. It is a missing infrastructure layer.
这不是特性，这是缺失的基础设施层。
HTTP gave the internet a shared language for documents.
HTTP 给互联网提供了文档的通用语言。
AMCP gives AI a shared protocol for memory.
AMCP 给 AI 提供了记忆的通用协议。
AMCP (AI Memory Communication Protocol) is a complete 7-layer, rigorous, open protocol for communication between AI nodes and memory infrastructure.
AMCP（AI 记忆通信协议）是一套完整的 七层、刚性、开放协议，用于 AI 节点与记忆基础设施之间的通信。
Unlike existing approaches, AMCP is not a gentleman's agreement. It has:
不同于现有方案，AMCP 不是君子协定，它有：
| Feature / 特性 | Description / 说明 |
|---|---|
| Binary wire format / 二进制帧格式 | 50-byte header, CRC-32C, AES-256-GCM encryption / 50字节帧头，CRC-32C校验，AES-256-GCM加密 |
| Protocol violation enforcement / 协议违规强制执行 | 0x00FF forced disconnect — no silent failures / 0x00FF 强制断开，拒绝静默漂移 |
| Structured knowledge format (AMF) / 结构化知识格式 | 7 types, SPO triples, decay models, content-addressed IDs / 7种类型，主谓宾三元组，衰减模型，内容寻址ID |
| Context Scheduling Engine (CSE) / 上下文调度引擎 | ROI-ranked auto assembly, deterministic, <100ms / ROI排序自动组装，确定性，<100ms |
| Distributed storage tiers / 分层分布式存储 | Edge (offline) → Warm (LAN) → Cloud (cold) / 端侧（离线）→ 边缘（局域网）→ 云端（冷存） |
| Causal consistency / 因果一致性 | HLC + content-addressing + 3-layer consistency / 混合逻辑时钟+内容寻址+三层一致性 |
| AMQL query language / AMQL查询语言 | Semantic, temporal, causal queries across any backend / 跨后端语义、时态、因果查询 |

cat spec/conformance/level-1.mdThe fastest path to AMCP compatibility is passing the 8 Level-1 conformance tests.
通往 AMCP 兼容性的最快路径是通过 8 项 Level-1 一致性测试。
T1-01 Frame magic bytes validation 帧魔数验证
T1-02 CAPABILITY_HELLO on connect 连接时发送能力声明
T1-03 0x00FF on protocol violation 协议违规时强制断开
T1-04 AMF schema validation AMF格式验证
T1-05 Knowledge immutability enforcement 知识不可变性
T1-06 State machine enforcement 状态机约束
T1-07 Checksum silent discard 校验失败静默丢弃
T1-08 Content-addressed knowledge_id 内容寻址ID计算
