Discrete Fourier Transforms (scipy.fft)

Can a transform pipeline recover known frequencies and amplitudes under declared sampling and normalization conventions?

The evaluator generates analytic sinusoids and impulses, computes a direct small-size transform and independently checks reconstruction and energy identities.

What you could produce

• A versioned minimal protocol, evaluator-owned test cases, and a comparison report with numerical/statistical uncertainty and failures.

Before you use it

• SciPy 1.18.0
• Compatible NumPy and native numerical-library build; exact environment not prepared

Limits to keep in view

• No upstream example, source package, build hook or submitted code was executed.
• The current qualified pilot accepts only self-contained Python 3.13 with a 90-second deadline. This reference's package/runtime is not qualified for that path.
• The proposed protocol requires bounded resource estimates and an independently controlled evaluator before any scientific execution claim.
