 When working in a Jerboa project, **ONLY modify files in the current repo** unless the user explicitly names another path.
 
 Common sibling repos that exist but must NOT be touched without explicit instruction:
+- `~/mine/jerboa-emacs` — **NEVER touch**. Another model owns it.
 - `~/mine/jerboa-mcp` — Legacy node MCP, superseded. The active MCP server now lives in THIS repo at `mcp/` + `data/`. Don't modify the legacy repo unless told.
 - `~/mine/jerboa-shell` — Only modify when user explicitly says to work there.
 - `~/mine/gerbil-mcp` — **NEVER touch**. Deprecated.
