Memory is prone to poisoning. Also, I want to be able to take my toys and go elsewhere.
My method is seven layers of files, administered differently: meta-knowledge, project seed, LLM wiki, code, tickets and todos, chat logs, artifactory. Ordered idea-to-reality. All git repos. That outgrows any context window pretty soon. My way out of that trap is to use links, both wiki links and git permalinks.
