 **Notes CRUD + note_* tools + tool execution framework**
 - Enables the LLM to be genuinely useful beyond ephemeral chat.
 - Requires: tool execution in completion handler (the plumbing for
   _all_ tools).
 - This phase builds the tool calling infrastructure that everything
   else uses.

+### Phase 5: Embeddings + Knowledge Bases
 **Embedding pipeline + pgvector + KB CRUD + kb_search tool**
 - Depends on: tool execution framework (Phase 2).

 **Auto-compaction service**
 - Depends on: utility LLM calling (same as task runner).
 - Channel-scoped: compacts any channel that exceeds context threshold.
 - Can be built alongside or after KB (similar backend pattern:
   background job that calls an LLM).

 - Creates `type: 'service'` channels with no human members.
 - Depends on: completion handler, tool execution, notes, web search.
 - The capstone: everything below it combined into autonomous agents.
