Fields
Every field type, its settings and its limits
The catalogue: each type's id, label, which group it belongs to in the picker, whether it is stored, computed or a relation, whether anybody may write to it, its character or magnitude limit, and the shape of its config.
GET/v1/field-types
Read it before inventing a setting, a config key that does not belong to the type is a validation error, not something quietly ignored.
Requires the schema:read scope. Operation fields.types. MCP tool fields_types. CLI, once published: gtable fields types.
