Overview

Markdown (truth)  +  SQLite (state)  +  LanceDB (index)

Markdown-first (md is truth)
├── index rebuildable from md       →  zero external services, no ops overhead
├── md portable + API isomorphic    →  edge prototype migrates to cloud as-is
├── md partitioned by owner dir     →  user / agent / knowledge physically isolated
└── md is a text carrier            →  multimodal content unified under one protocol
