Function llm_name 

pub fn llm_name(contract_id: &str) -> String

LLM-facing tool name = <area>_<leaf> of a contract_id, where <area> is the segment immediately before the leaf. Examples: robonix/primitive/camera/snapshot → camera_snapshot robonix/primitive/lidar/snapshot → lidar_snapshot robonix/primitive/chassis/move → chassis_move robonix/service/memory/search → memory_search robonix/service/navigation/navigate → navigation_navigate

Plain leaf-only used to be enough but multiple providers share leaves (snapshot on camera AND lidar). The OpenAI tool-list collapses duplicates and the LLM picks the wrong one. Prefixing with the area segment disambiguates while staying short and human-readable.

Executor still routes via the full contract_id (the leaf is the MCP-server-side tool name, which is unique within a single driver’s FastMCP server). This function only renames at the LLM-↔-pilot boundary.
