 ## Layout
-- `src/main.cpp` – entry point (stub until qtmcp wired)
+- `src/main.cpp` – QtMcp-backed entry point (stdio/SSE backends)
 - `src/mcp/ToolSchemas.json` – JSON Schemas for MCP tools
 - `src/memory/` – interfaces for embedder and vector store
 - `docs/` – design notes
 
 ## Next
-- Add qtmcp dependency and implement server with tool registration.
+- Add richer tool metadata + prompt support on top of the qtmcp server.
 - Implement adapters: embedder(s) + vector store(s).
 - Flesh out Postgres DAL paths (prepared statements + pgvector wiring).
