 *   **Conditions**: A condition schema is the contract defining the mathematical operations allowed on a primitive field. For example, a `string.condition` allows `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$of` (IN), and `$nof` (NOT IN). 
     *   **Enum Conditions**: When JSPG synthesizes an enum, it dynamically generates an `<enum>.condition` (e.g., `address_kind.condition`). This strongly-typed condition perfectly mirrors the operations of a `string.condition`, but strictly limits the arrays and inputs of `$eq`, `$ne`, `$of`, and `$nof` to the exact variations defined by that Enum. This context ensures that UI generators know exactly when to render `<Select>` dropdowns instead of generic `<Text>` boxes.
+    *   **Pre-compiled Condition and Filter Mapping**: To prevent redundant double-wrapping of search structures, any schema property whose type is already a `.condition` or `.filter` type (such as `"string.condition"` or `"$kind.filter"`) maps directly to itself during filter synthesis rather than receiving a redundant `.filter` suffix.
 *   **Filters**: A filter schema (e.g., `person.filter`) is an object containing condition properties used to filter entities. It natively supports structural composition:
     *   **Inherited Properties**: Filters automatically inherit all valid database columns from their base type schema, immediately converting them to their respective `.condition` schemas.
     *   **Relational Proxies**: If a table has a foreign key to another table, the filter automatically generates a proxy property pointing to the related entity's filter (e.g., the `person` filter automatically gains an `organization` property that points to `organization.filter`), allowing infinitely deep nested queries natively.
