     *   **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.
     *   **Logical Operators (`$and`, `$or`)**: Every filter automatically includes `$and` and `$or` arrays, which recursively accept the exact same filter schema, allowing complex logical grouping.
-    *   **Ad-Hoc Extensions (`ad_hoc`)**: Fields stored purely in JSONB bubbles that lack formal database columns can still be queried using the `ad_hoc` object, which passes standard, unvalidated string conditions.

+### Trait-Based Schema Composition (`traits` & `include`)
+Traits are reusable, non-generating schema fragments used to share properties and relationships horizontally across multiple schemas. They do not generate separate Go/Dart classes.
+
+*   **Traits Namespace**: Defined in a sibling `"traits"` block next to `"schemas"` inside table comments:
+    ```json
+    "traits": {
+      "emailable": {
+        "properties": {
+          "email_addresses": {
+            "type": "array",
+            "items": { "type": "contact", "properties": { "target": { "type": "email_address" } } }
+          }
+        }
+      }
+    }
+    ```
+*   **Include Keyword**: Schemas or traits can use the `"include"` array to compose traits or other schemas:
+    ```json
+    "full.person": {
+      "type": "person",
+      "include": ["contactable", "owner"]
+    }
+    ```
+*   **Resolution and Merging**: During `Database::new()`, includes are resolved and merged at the raw JSON level:
+    *   **`properties` / `patternProperties`**: Map keys from the host schema override/shadow included traits.
+    *   **`required` / `display`**: Lists are merged and deduped.
+    *   **`dependencies`**: Merged by combining and deduping lists.
+    *   **Scalars / Arrays / Items**: Host definitions completely override included traits.
+    *   The `"include"` keyword is stripped, and `"traits"` maps are omitted from serialization.
