+- 根据平台数据集 ID 生成 LLaMA-Factory dataset key 和 `{dataset_dir}/dataset_info.json`。
+- 单文件数据集使用一个 dataset key，多文件数据集拆分为多个 key 并通过逗号组合传入 `--dataset`。
+- 正式启动前由应用侧同步当前数据集文件到目标算力节点，确保训练使用最新激活版本。

+| Priority | Scope | Implemented content | Remaining production hardening |
+| --- | --- | --- | --- |
+| P1 | Training runtime assets | Compute scans real `checkpoint-*` directories; backend persists checkpoints to `fine_tune_checkpoints`; backend parses log metrics into `fine_tune_metrics`; completed training auto-registers a trained model with its real output directory. | Add full TensorBoard event parsing and retention/cleanup execution policies. |
+| P2 | Model merge/export | `/modelTF/model-manage/merge` submits `llamafactory-cli export` through Compute; merge/export jobs are recorded in `compute_jobs` and `model_export_jobs`; trained model artifacts are recorded in `model_artifacts`; base->trained and merge/export relations are recorded in `model_lineage`; APIs expose artifacts, lineage and export jobs. | Add frontend polling/status panels for export jobs and richer artifact checksum generation during long-running export. |
+| P3 | Compute ops | `compute_jobs` and `gpu_allocations` are updated from runtime polling; training start uses `scheduler_locks` to serialize node selection and GPU pre-allocation; terminal task states release GPU allocations; resource replica drift check and repair-pending APIs are available; `scripts/ops_diagnostics.py` checks backend, PostgreSQL, Compute health, GPU discovery and Compute jobs. | Add dedicated scheduler worker, automatic replica repair execution from authoritative source metadata, and lock timeout alarms. |
