Module condition 

GraphqlCondition — the structured filter type for the GraphQL adapter.

Conditions are kept abstract (field/op/value) and rendered to JSON at request time by the dialect attached to the data source. The two dialects that ship today:

• FilterDialect::Hasura — { field: { _eq: v }, _and: [...], _or: [...], _not: {...} }. Full operator coverage.
• FilterDialect::Generic — flat argument object: { field: v }. Equality only; non-eq operators error at render time. Used by hand-rolled schemas like the SpaceX public API.

Postgraphile / Relay-cursor styles can be added as further dialects without changing the condition surface.
