Knowledge-Management

Most memory systems for AI agents treat knowledge as a key-value store. Write a fact, overwrite it later, old value is gone. That works for simple preferences — “use dark mode” doesn’t need a paper trail. But knowledge that evolves over time is a different problem. When a design decision turns out to be wrong, or a project’s architecture shifts, or a dependency gets replaced, you don’t just want the current answer. You want to know what you believed before, when it changed, and ideally why. Losing that history means losing the reasoning trail, and reasoning is the expensive part. Memstore’s supersession system brings version control semantics to AI memory: facts get replaced, not erased, and the full chain of revisions is preserved.
