The first pass already has the evidence and says nothing about what it means. When two schemes come back with primitive volumes related by a small integer - or by sqrt(3), which is the hexagonal harmonic and is not a whole number - one of them is the other's axis harmonic, and what decides between them is the beam centre to a fraction of a pixel. The mechanism is that the J0 law is about the FFT AMPLITUDE, which is translation-invariant. A centre error along the spindle translates the derotated cloud rigidly, so the transform cannot see it, the peaks stay sharp, and the lattice fit that follows - whose origin is the beam, and which is not translation-invariant - commits with confidence to a sub-multiple. Measured on a deposited dataset: 0.12 px of centre, 0.09 px of it across the spindle against a 2.78 px need, is the whole difference between the deposited cell and a halved axis, and the halved one is the answer that indexed MORE frames - 100.00 % against 99.23 %. So the message is deliberately not conditioned on any indexing-quality signal, and it is taken over the whole pair rather than only over the tie: on this failure the frame count points the wrong way, which is exactly why it cannot arbitrate. Nothing is decided differently; the integer-subcell tie-break below is unchanged.
