defect in YAML: the same member field "id" declared twice in inheritance between ComputerToolCallOutput and ComputerToolCallOutputResource

[zijianhuang]

    ComputerToolCallOutput:
      type: object
      title: Computer tool call output
      description: |
        The output of a computer tool call.
      properties:
        type:
          type: string
          description: >
            The type of the computer tool call output. Always
            `computer_call_output`.
          enum:
            - computer_call_output
          default: computer_call_output
          x-stainless-const: true
        id:
          type: string
          description: |
            The ID of the computer tool call output.

......

    ComputerToolCallOutputResource:
      allOf:
        - $ref: "#/components/schemas/ComputerToolCallOutput"
        - type: object
          properties:
            id:
              type: string
              description: |
                The unique ID of the computer call tool output.
          required:
            - id

The only difference is, in derived class ComputerToolCallOutputResource, "id" becomes required.

A decent IDE or compiler will warn about such defect in OO inheritance, though the defect may be intentional.

Generated C# codes is like:

	/// <summary>
	/// The output of a computer tool call.
	///
	/// </summary>
	public class ComputerToolCallOutput
	{

		/// <summary>
		/// The type of the computer tool call output. Always `computer_call_output`.
		///
		/// Required
		/// </summary>
		[System.ComponentModel.DefaultValue(ComputerToolCallOutputType.computer_call_output)]
		[System.ComponentModel.DataAnnotations.Required()]
		public ComputerToolCallOutputType Type { get; set; } = ComputerToolCallOutputType.computer_call_output;

		/// <summary>
		/// The ID of the computer tool call output.
		///
		/// </summary>
		public string Id { get; set; }

		/// <summary>
		/// The ID of the computer tool call that produced the output.
		///
		/// Required
		/// </summary>
		[System.ComponentModel.DataAnnotations.Required()]
		public string Call_id { get; set; }

		/// <summary>
		/// The safety checks reported by the API that have been acknowledged by the 
		///developer.
		///
		/// </summary>
		public ComputerToolCallSafetyCheck[] Acknowledged_safety_checks { get; set; }

		/// <summary>

		///

		[System.ComponentModel.DataAnnotations.Required()]
		public ComputerScreenshotImage Output { get; set; }

		/// <summary>
		/// The status of the message input. One of `in_progress`, `completed`, or
		///`incomplete`. Populated when input items are returned via API.
		///
		/// </summary>
		public ComputerToolCallStatus Status { get; set; }
	}

	public enum ComputerToolCallOutputType
	{

		computer_call_output = 0,
	}

	public class ComputerToolCallOutputResource : ComputerToolCallOutput
	{

		/// <summary>
		/// The unique ID of the computer call tool output.
		///
		/// Required
		/// </summary>
		[System.ComponentModel.DataAnnotations.Required()]
		public string Id { get; set; }
	}

VS IDE or C# compiler will warn about dirty inheritance.
