What the article says around this equation
Reproduction will require more than releasing a final array. Each numerical record must carry the spin size, Hilbert-space ordering, probe preparation, coupling normalization, interaction sequence, fragment partition, orientation samples, Haar weights, optimizer settings, random seed, and software versions. Density matrices will be checked for unit trace, Hermiticity, and nonnegative spectrum within a declared floating-point tolerance after every partial trace. The sequential channel will be compared against direct full-unitary propagation for small j and N , where both are computationally affordable. Only after those checks agree may tensor-network or symmetry-reduced methods replace the…

Reproduction will require more than releasing a final array. Each numerical record must carry the spin size, Hilbert-space ordering, probe preparation, coupling normalization, interaction sequence, fragment partition, orientation samples, Haar weights, optimizer settings, random seed, and software versions. Density matrices will be checked for unit trace, Hermiticity, and nonnegative spectrum within a declared floating-point tolerance after every partial trace. The sequential channel will be compared against direct full-unitary propagation for small j and N , where both are computationally affordable. Only after those checks agree may tensor-network or symmetry-reduced methods replace the direct calculation at larger size.
