FactLayer
Rank #11,119glama/Rubber-Duck-Screaming/factlayer
Every memory framework treats a frequently-used fact as trustworthy forever but "still relevant" and "still true" aren't the same thing.A customer's city, a teammate's role, a project's status: these age quietly, and nothing catches it until an agent confidently repeats something that stopped being true months ago. FactLayer is a lightweight check that sits on top of whatever memory system you.
