Promise Settlement Handler with Robust Error Recovery

Build a utility that safely processes multiple asynchronous operations, even when some promises have been tampered with or exhibit unusual error behavior. The system must handle edge cases where promise implementations are non-standard or have been modified at runtime.

Capabilities

Handles Modified Promise Behavior

• When a promise object has a .then() method that throws an error when accessed, the system still processes that promise and returns settlement information @test
• When multiple promises include some with throwing .then() methods mixed with normal promises, all are processed correctly @test

Captures Various Error Types

• When promises reject with different error types (Error objects, strings, numbers), all rejection reasons are captured accurately in the result @test
• When promises are a mix of fulfilled and rejected states, all results maintain consistent formatting with appropriate status, value, and reason fields @test
