Two-pass rotation indexing scored each first-pass scheme by how many validation frames it indexes, but a spurious axis multiple (2x/3x...) indexes every frame its true sub-cell does, so the count saturates - both schemes reach the same frame total - and the tie fell to whichever scheme ran first. When that first scheme's full-rotation FFT resolves a true axis only as a 2x/3x harmonic of its length (the fundamental can sit far below the harmonic in the full-360 cloud), it commits a multiplied cell and the dataset collapses to P1, even though the other scheme already found the true cell. Add an integer-supercell cross-scheme tie-break: when two schemes tie on frames but their cell volumes differ by a near-integer factor >=2, the larger is the spurious supercell and the smaller true cell is adopted, independent of scheme order. The near-integer test distinguishes a real axis multiplication from a centering coincidence (a rhombohedral H cell vs its C2 sub-cell is 1.5x and is left alone). Validated de-novo across the rotation regression battery: the affected dataset now indexes its correct space group, the override triggers only where an axis was multiplied, and every other dataset is unchanged.
