Function compileFunctionOutput 

pub fn compileFunctionOutput(
    function: JsValue,
    input: JsValue,
    task_outputs: JsValue,
) -> Result<JsValue, JsValue>

Computes the final output of a Function given input and task results.

Evaluates the function’s output expression using the provided input data and task outputs. Also validates that the output meets constraints:

• Scalar functions: output must be in [0, 1]
• Vector functions: output must sum to approximately 1

Arguments

• function - JavaScript object representing a Function definition
• input - JavaScript object representing the function input
• task_outputs - Array of task outputs (from actual execution or mocked)

Returns

An object with:

• output: The computed scalar or vector output
• valid: Boolean indicating if the output meets constraints

Errors

Returns an error string if expression evaluation fails.
