ViperEkura 4e508afa2d fix : SFT pipeline position_ids default & doc boundary preservation ... - change position_ids_mode default from "none" to "doc_reset" so SFT preprocessing always generates position_ids (was causing dataset load KeyError) - generate per-doc position_ids before packing (doc_reset mode), preserving document boundaries for BFD packing (cross-doc attention leak fix) - change _align_bucket padding from [1] to [0] to avoid accidentally training on loss_mask padding		2026-07-04 15:59:11 +08:00
