【系统声明与边界界定】
本项目（九章矩阵计算系统 libcore_final）仅为"数理逻辑与物理自洽性"的编程法验证原型，非最终商业交付件。
-
验证目标已达成：本代码完整实现了从网络层(6×6)到芯片层(4×4)的三维流形拓扑、光电耦合换能（OE矩阵）、维度坍缩缓冲、以及基于物理密度的反压与自愈机制。证明矩阵流形计算在数理与物理层面高度自洽，无需操作系统级干预。
-
核心理论保留 ：本系统涉及网络管理与流形控制的数学模型及控制论原理，属于底层核心理论，不予公开。当前代码中的管理流形仅作状态采样展示，不包含任何自动寻优与流形变步长控制算法。
-
工程与商业扩展留白 ：当前系统已具备拓扑骨架、光电接口、反压机制与审计计费锚点。关于多租户隔离的最终实现、节点级死亡判定的高可用闭环、以及生产级优雅停机等工程细节，留待实际部署方根据具体物理环境与商业规则自行补全。
