brain-mcp-tool-refs-stale-use-vault-mcp

All brain_* MCP tool calls (brain_search_learnings, brain_submit_learning, brain_record_decision, brain_list_pending_handoffs, etc.) were silently broken — no brain-mcp server exists. The system uses vault-mcp with vault_* tools exclusively. These stale refs were found in aj-ea CLAUDE.md, aj-ea MEMORY.md, and feedback_st_proactive_use.md in BOTH workspaces. Any future references to brain_* are incorrect.
