Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Standard electromagnetic theory and electrodynamics possess fundamental Lorentz invariants, such as the quadratic field invariants.

The analysis

The claim is a well-established physical fact concerning classical electrodynamics and special relativity. Papers [1] and [2] directly discuss the mathematical invariants of the electromagnetic field (specifically Lorentz scalars and pseudoscalars). The remaining papers are tangential or concern distinct topics (e.g., condensed matter, neural dynamics, cosmology).
