Crate fathomdb_query 

FathomDB query — the JSON-filter AST and its validation surface.

An internal leaf crate of the FathomDB workspace, kept separate so the filter grammar can be validated without pulling in the engine. Application code should depend on the fathomdb facade crate instead, which exposes the supported filter types (Predicate, ScalarValue, ComparisonOp, SearchFilter) as governed surface.

The filter grammar is deliberately closed — a fixed set of comparison operators over an allowlisted set of JSON paths — rather than an open DSL. Values are always bound as parameterized SQL and never interpolated.
