1. [Capability Map](capability-map.md): find the right page by "what I want to do".
2. [Execution Layer Selection](execution-layer-selection.md): choose between ModelRequest, AgentExecution, TaskDAG, and TriggerFlow.
3. [Glossary](glossary.md): shared terminology, API names, and migration language.
