 }
 ```

+### Single Record as Object (Default Behavior)
+
+By default, RestHeadSpec automatically converts single-element arrays into objects for cleaner API responses. This provides a better developer experience when fetching individual records.
+
+**Default behavior (enabled)**:
+```http
+GET /public/users/123
+```
+```json
+{
+  "success": true,
+  "data": { "id": 123, "name": "John", "email": "john@example.com" }
+}
+```
+
+Instead of:
+```json
+{
+  "success": true,
+  "data": [{ "id": 123, "name": "John", "email": "john@example.com" }]
+}
+```
+
+**To disable** (force arrays for consistency):
+```http
+GET /public/users/123
+X-Single-Record-As-Object: false
+```
+```json
+{
+  "success": true,
+  "data": [{ "id": 123, "name": "John", "email": "john@example.com" }]
+}
+```
+
+**How it works**:
+- When a query returns exactly **one record**, it's returned as an object
+- When a query returns **multiple records**, they're returned as an array
+- Set `X-Single-Record-As-Object: false` to always receive arrays
+- Works with all response formats (simple, detail, syncfusion)
+- Applies to both read operations and create/update returning clauses
+
+**Benefits**:
+- Cleaner API responses for single-record queries
+- No need to unwrap single-element arrays on the client side
+- Better TypeScript/type inference support
+- Consistent with common REST API patterns
+- Backward compatible via header opt-out
+

+# X-Files Header Usage
+
+The `x-files` header allows you to configure complex query options using a single JSON object. The XFiles configuration is parsed and populates the `ExtendedRequestOptions` fields, which means it integrates seamlessly with the existing query building system.
+
+## Architecture
+
+When an `x-files` header is received:
+1. It's parsed into an `XFiles` struct
+2. The `XFiles` fields populate the `ExtendedRequestOptions` (columns, filters, sort, preload, etc.)
+3. The normal query building process applies these options to the SQL query
+4. This allows x-files to work alongside individual headers if needed
+
+## Basic Example
+
+```http
+GET /public/users
+X-Files: {"tablename":"users","columns":["id","name","email"],"limit":"10","offset":"0"}
+```
+
+## Complete Example
+
+```http
+GET /public/users
+X-Files: {
+  "tablename": "users",
+  "schema": "public",
+  "columns": ["id", "name", "email", "created_at"],
+  "omit_columns": [],
+  "sort": ["-created_at", "name"],
+  "limit": "50",
+  "offset": "0",
+  "filter_fields": [
+    {
+      "field": "status",
+      "operator": "eq",
+      "value": "active"
+    },
+    {
+      "field": "age",
+      "operator": "gt",
+      "value": "18"
+    }
+  ],
+  "sql_and": ["deleted_at IS NULL"],
+  "sql_or": [],
+  "cql_columns": ["UPPER(name)"],
+  "skipcount": false,
+  "distinct": false
+}
+```
+
+## Supported Filter Operators
+
+- `eq` - equals
+- `neq` - not equals
+- `gt` - greater than
+- `gte` - greater than or equals
+- `lt` - less than
+- `lte` - less than or equals
+- `like` - SQL LIKE
+- `ilike` - case-insensitive LIKE
+- `in` - IN clause
+- `between` - between (exclusive)
+- `between_inclusive` - between (inclusive)
+- `is_null` - is NULL
+- `is_not_null` - is NOT NULL
+
+## Sorting
+
+Sort fields can be prefixed with:
+- `+` for ascending (default)
+- `-` for descending
+
+Examples:
+- `"sort": ["name"]` - ascending by name
+- `"sort": ["-created_at"]` - descending by created_at
+- `"sort": ["-created_at", "name"]` - multiple sorts
+
+## Computed Columns (CQL)
+
+Use `cql_columns` to add computed SQL expressions:
+
+```json
+{
+  "cql_columns": [
+    "UPPER(name)",
+    "CONCAT(first_name, ' ', last_name)"
+  ]
+}
+```
+
+These will be available as `cql1`, `cql2`, etc. in the response.
+
+## Cursor Pagination
+
+```json
+{
+  "cursor_forward": "eyJpZCI6MTAwfQ==",
+  "cursor_backward": ""
+}
+```
+
+## Base64 Encoding
+
+For complex JSON, you can base64-encode the value and prefix it with `ZIP_` or `__`:
+
+```http
+GET /public/users
+X-Files: ZIP_eyJ0YWJsZW5hbWUiOiJ1c2VycyIsImxpbWl0IjoiMTAifQ==
+```
+
+## XFiles Struct Reference
+
+```go
+type XFiles struct {
+    TableName      string      `json:"tablename"`
+    Schema         string      `json:"schema"`
+    PrimaryKey     string      `json:"primarykey"`
+    ForeignKey     string      `json:"foreignkey"`
+    RelatedKey     string      `json:"relatedkey"`
+    Sort           []string    `json:"sort"`
+    Prefix         string      `json:"prefix"`
+    Editable       bool        `json:"editable"`
+    Recursive      bool        `json:"recursive"`
+    Expand         bool        `json:"expand"`
+    Rownumber      bool        `json:"rownumber"`
+    Skipcount      bool        `json:"skipcount"`
+    Offset         json.Number `json:"offset"`
+    Limit          json.Number `json:"limit"`
+    Columns        []string    `json:"columns"`
+    OmitColumns    []string    `json:"omit_columns"`
+    CQLColumns     []string    `json:"cql_columns"`
+    SqlJoins       []string    `json:"sql_joins"`
+    SqlOr          []string    `json:"sql_or"`
+    SqlAnd         []string    `json:"sql_and"`
+    FilterFields   []struct {
+        Field    string `json:"field"`
+        Value    string `json:"value"`
+        Operator string `json:"operator"`
+    } `json:"filter_fields"`
+    CursorForward  string `json:"cursor_forward"`
+    CursorBackward string `json:"cursor_backward"`
+}
+```
+
+## Recursive Preloading with ParentTables and ChildTables
+
+XFiles now supports recursive preloading of related entities:
+
+```json
+{
+  "tablename": "users",
+  "columns": ["id", "name"],
+  "limit": "10",
+  "parenttables": [
+    {
+      "tablename": "Company",
+      "columns": ["id", "name", "industry"],
+      "sort": ["-created_at"]
+    }
+  ],
+  "childtables": [
+    {
+      "tablename": "Orders",
+      "columns": ["id", "total", "status"],
+      "limit": "5",
+      "sort": ["-order_date"],
+      "filter_fields": [
+        {"field": "status", "operator": "eq", "value": "completed"}
+      ],
+      "childtables": [
+        {
+          "tablename": "OrderItems",
+          "columns": ["id", "product_name", "quantity"],
+          "recursive": true
+        }
+      ]
+    }
+  ]
+}
+```
+
+### How Recursive Preloading Works
+
+- **ParentTables**: Preloads parent relationships (e.g., User -> Company)
+- **ChildTables**: Preloads child relationships (e.g., User -> Orders -> OrderItems)
+- **Recursive**: When `true`, continues preloading the same relation recursively
+- Each nested table can have its own:
+  - Column selection (`columns`, `omit_columns`)
+  - Filtering (`filter_fields`, `sql_and`)
+  - Sorting (`sort`)
+  - Pagination (`limit`)
+  - Further nesting (`parenttables`, `childtables`)
+
+### Relation Path Building
+
+Relations are built as dot-separated paths:
+- `Company` (direct parent)
+- `Orders` (direct child)
+- `Orders.OrderItems` (nested child)
+- `Orders.OrderItems.Product` (deeply nested)
+
+## Notes
+
+- Individual headers (like `x-select-fields`, `x-sort`, etc.) can still be used alongside `x-files`
+- X-Files populates `ExtendedRequestOptions` which is then processed by the normal query building logic
+- ParentTables and ChildTables are converted to `PreloadOption` entries with full support for:
+  - Column selection
+  - Filtering
+  - Sorting
+  - Limit
+  - Recursive nesting
+- The relation name in ParentTables/ChildTables should match the GORM/Bun relation field name on the model
