Reference
Look up the exact details that apply across Spiral services and SDKs.
Look up the exact details that apply everywhere in Spiral: the SPQL function library and its data types, permissions, error names, and how to write a Table address. Guides and API pages for one service live in that service's section of the Services tab.
Shared reference
Find every SPQL function with its signatures and argument types.
Find the primitive, nested, and semantic types that function signatures use.
Find the typed elements that each Foxglove and ROS 2 topic of an MCAP recording imports as.
Find each permission, the service that checks it, and the OAuth scope that delegates it.
Look up a named error such as Catalog:StaleHead: what it means and which operations return it.
Name a Table at a branch, a Project commit, or an exact version with path@ref.
Find the hosts, authentication, and conventions that every service API shares.
