Accumulation.__neg__ passed y_2 = numpy.array(self.y_square), storing a 2D ndarray. A later __iadd__ on an accumulation with ndarray y_square crashed with AttributeError at the y_square.append sites (992, 1064). - __neg__ now passes a per-channel copy (values unchanged: sums of squares are invariant under negation) - __init__ normalizes ndarray y_2 to a list, so external callers cannot reintroduce the bug - y_square annotated as _YChannels Clears the remaining pyrefly errors at Accumulation.py:992 and :1064 (74 -> 72). Unit tests reproduce both crashes and pass with the fix. Generated by Mistral Vibe. Co-Authored-By: Mistral Vibe <vibe@mistral.ai>
