ViperEkura 88ec786e39 fix: memmap mode=r, tool parser json.loads, greedy decode 2026-07-19 16:38:28 +08:00
ViperEkura a74e5b91a3 feat: add record-mode to Store for DPO/GRPO 
- Store gains fetch_record/num_records alongside stream fetch/__len__
- save_bin/load_bin support per-record offsets via record_keys param
- H5Store/MmapStore/JsonlStore all support dual stream+record access
- DPODataset/GRPODataset use fetch_record, no cross-record concat
- dpo_collate_fn + collate_fn wired through TrainConfig
- fixes attention context leakage in DPO from windowed concatenation

ViperEkura 84ed2327f5 feat: add --resume flag to decouple weight loading from training resumption 
- Add --resume bool flag to train.py CLI
- --param_path always loads weights only by default
- --resume restores epoch, consumed_samples, optimizer & scheduler
- Checkpoint.load() now preserves full meta dict
- Update test_early_stopping to use new param_path/resume API

ViperEkura b092316385 feat : add distributed checkpoint via executor checkpoint_context 
- Add checkpoint_context context manager to BaseExecutor with entry/exit barrier
- Add _gather_state_dict hook overridden per executor (template method)
- DDPExecutor skips unwrap on non-rank-0 to avoid redundant state_dict gather
- FSDPExecutor uses rank0_only=True to reduce memory on non-writers
- Remove redundant rank-0 guard from Checkpoint.save and manual barrier from Callback

- Reuse PipelineConfig schema for JSONL dataset configuration
- Update detect_format to recognize JSONL directories and files
- Move save_h5/load_h5/save_bin/load_bin to astrai/serialization
- Split astrai/serialization.py into checkpoint/dataset submodules
- Add tests for JSONL detection, seq/SFT stores, and config roundtrip
