张宗平	8aeddebce9	test(m4): instruct_check unit tests + unbuffered training scripts ... - tests/test_instruct_check.py: cover load_by_category (bucketing/cap/seed determinism/short-pool/blank-line) and _forecast_list (nested/flat/ dict/garbage). 8 tests pass. - train_stage{1,2}.sh: export PYTHONPATH=src + PYTHONUNBUFFERED=1 so future background runs stream logs live (current stage2 run is block-buffered).	2026-06-30 07:27:03 +00:00
张宗平	357e2e60bd	feat(m4): stage 2 SFT training script (LoRA r=16) + smoke (T4.1) ... - src/tsmm/train/stage2.py: loads stage1 ckpt (optional), freeze_llm + enable_lora(r=16) on q/v_proj, masked LM loss on sft.jsonl, bs=4/grad_accum=8/ ctx=1024/BF16/gradient checkpointing, ckpt every 2000 steps (encoder+projector state + peft LoRA adapter via save_pretrained). - scripts/train_stage2.sh: wrapper with design defaults. - Smoke verified: --max_steps 4, LoRA injected, finite loss, peak 3.29 GB (≤11GB budget), ckpt+adapter saved.	2026-06-30 03:11:00 +00:00
