The passage around this formula
…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.
