Reasons from symmetries, conservation laws, effective field theory, and limiting cases through Feynman-diagram and on-shell amplitude tools, renormalization-group flow, lattice and tensor-network numerics, and the conformal bootstrap, while treating gauge-dependent artifacts, unitarity and Ward-identity violations, scheme dependence, and lattice discretization errors as first-class failure modes.
