The Graph

Everything the pipeline produces lands in one structure: a graph of how you think, held in four stores on your own disk. The vault stays plain files you can read. The rest is the Oracle's working memory.

Four kinds of node

The four stores hold the same knowledge from four angles. One keeps the record (conviction history, your routines, the bookkeeping that ties the rest together). One holds the graph itself, the nodes and the connections between them. One holds a mathematical fingerprint of each passage, so the Oracle can find work by meaning rather than exact words. And one is the filesystem, where your vault stays plain files alongside Existential's own internal files. The split exists so each kind of access is served well, and so the whole thing stays on your machine. The pieces matter, but the graph is where their shape is held: the connections across your thinking.

Inside the graph, every piece of structure the Oracle builds is one of four kinds of node.

  • Document, a note exactly as you wrote or spoke it.
  • Chunk, a passage that holds one thought, scored for conviction.
  • Concept, a named idea that recurs across your notes.
  • Category, an epistemic place: question, claim, observation, plan.
