Rete: Incremental Rule Matching, from First Principles to Go

A rule engine repeatedly asks which combinations of current facts satisfy its rules. Rete keeps those matches up to date by remembering filtered facts and partial matches, then propagating changes through a shared network. We will derive that network and implement a small matcher in Go.

Derive Rete from a naïve rule matcher, then build a runnable Go example with shared filters, real joins, fact retraction, and a separate agenda.

Rete 算法：从基本原理到 Go 增量规则匹配器

规则引擎反复回答一个问题：当前事实的哪些组合满足规则？Rete 保存已经过滤的事实和部分匹配结果，让变化沿共享网络传播，从而持续维护匹配结果。本文先推导这个网络，再用 Go 实现一个小型匹配器。

从朴素规则匹配器推导 Rete，并用可运行的 Go 示例实现共享过滤、真实关联、事实撤回，以及独立的待执行议程。
