What's this about?
A security researcher building an LLM memory system found they had accidentally built something closer to a program analysis tool — the structures needed to let a model remember a codebase across sessions turn out to be the structures static analysis has always used.
What is program analysis?
Reasoning about what a program does without running it: which functions call which, where a value can flow, which inputs can reach a dangerous operation. It is the foundation of every static security scanner. The convergence here is not a coincidence — "what does this agent need to remember about this codebase" and "what facts must a scanner track" are the same question, because both are trying to compress a program into the subset of facts that matter.
Why does this matter to you?

- It is a direct bridge between agent memory work and the security-scanning problem, from someone working on both.
- The practical implication: memory structures built for agents may be reusable as analysis artifacts, and vice versa.
- Coming from a security researcher rather than an agent-framework author makes the convergence more credible.
