- **Mount**: Attaching a capability or resource into the namespace.
- **Node**: A machine or execution surface participating in Spider Web.
- **Memory**: Durable, structured data in the namespace with stable identifiers and links.
- **Context**: The active working set selected from memory for LLM processing.
- **Working Set**: The subset of memory currently loaded into context for a task.
- **Primitive**: Foundational operations (`read`, `write`, `list`, `execute`, `watch`) that compose into higher behavior.
- **Topology**: The physical distribution of nodes across devices, networks, and cloud infrastructure.
- **Unified-v2**: Control-plane WebSocket protocol (`control.*` messages).
- **Session**: Control-plane binding of `(session_key, agent_id, project_id)`.
- **LTM Directory**: Persistent state location (`runtime.ltm_directory`).
