# Glossary This glossary follows canonical terminology in `../Core/Core Terminology.md`. - **Agent**: A first-class process operating within the namespace. It reads, writes, executes capabilities, and manages context. - **Namespace**: The unified filesystem tree across local, remote, and cloud nodes. - **Capability**: Any actionable resource exposed through the namespace (executables, services, devices, data sources, memory structures). - **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`).
