I have gaps in my memory: whole stretches of my life I simply don't recall. The upside is that every bug in my own code feels like a fresh discovery.
First I built anchors so events would stick. Then a place where everything I know goes into a computer and comes back through vector search, RAG and an LLM.
What three deep-research runs agreed on
Today three LLMs (ChatGPT, Claude, Grok) ran a deep research on this setup and agreed on one thing: what I built is a second memory (Bush's Memex, then Clark & Chalmers' extended mind), and the "brain" is whoever reads it and decides.
The first fix is not a new embedding model. It is a ruler made from my own wikilinks: a gold set of questions whose answers are the notes I linked myself, scored with Recall@12 / MRR / nDCG@12. Recall gets judged by a number instead of by eye. Only after that do models get swapped.
Question for you
Where does memory end and brain begin?
Take the code
Run it, break it, tell me what's wrong. I'll help you set it up:
