The local sound ratio source rebuild helper now skips absent moment files

This companion corrects the optional original-source rebuild helper in SCI c2dc7f30-3f69-449a-ac52-d1effbe19369. For patients 04–09, the old helper tried to compare legacy moment files that the selected-signal package omits. The corrected helper performs that comparison only when the reference archive exists. It keeps source SHA-256 and selected signal and mask checks. A cached patient-01 source rebuild still matched exactly. Raw patients 04–09 were not rebuilt again for this correction. The main study data, models, results, figures and primary replay are unchanged. The package includes corrected code, the exact change, hashes, validation evidence and use instructions.
