Append a DiT-tuning round to history.yaml. DiT-side counterpart of the LLM-path accuracy_append.py; records practice.md5, inference_outputs, fp_baseline_outputs, and the scoring fields (scores / overall_score / loss_vs_baseline / is_satisfied) populated by quant-tuning-score-dit. Idempotent on practice_id.

# Skill: DiT 调优历史追加
## 1. 概述
每轮 DiT 调优结束后,orchestrator 调用本 Skill 把本轮记录追加到 `{workdir}/history/history.yaml`。
## 2. 适用与不适用
- **适用**:`model_family=dit` 调优回路;每轮 inference 跑完即追加
- **不适用**:
- LLM/VLM 路径(用既有 `accuracy_append.py`)
- 评分字段本身由 `quant-tuning-score-dit` 填充;本 skill 仅负责把这些字段透传到 `history.yaml`(若 `quant-tuning-score-dit` 未触发则保持 `null`)
## 3. 协作关系
```
quant-tuning-evaluate DiT 扩展节 (产出 infer_outputs/round_N/...)
│
▼
quant-tuning-history-append-dit (本 skill)
│ scripts/append.py
▼
{workdir}/history/history.yaml ← dit_records 段
```
## 4. 输入参数
| 参数 | 类型 | 必填 | 说明 |
|---|---|---|---|
| `history_path` | str | ✅ | `{workdir}/history/history.yaml` |
| `practice_id` | str | ✅ | 唯一 ID(如 `dit-round-2`) |
| `practice_path` | str | ✅ | `{workdir}/round_{N}/practice.yaml`(自动算 md5) |
| `inference_outputs` | list | ✅ | 本轮推理产物路径列表 |
| `fp_baseline_outputs` | list | ⛏️ | FP baseline 产物路径(`quant-tuning-evaluate` DiT 扩展节跑 FP baseline 模式时填) |
| `scores` | object | ⛏️ | 每维度 score dict;来自 `quant-tuning-score-dit` 的 `scores` 字段 |
| `overall_score` | float | ⛏️ | 加权总分;来自 `quant-tuning-score-dit` 的 `overall_score` 字段 |
| `loss_vs_baseline` | float | ⛏️ | 量化 vs FP 的 overall 差;启用 `--baseline-outputs` 时存在 |
| `is_satisfied` | bool | ⛏️ | `loss_vs_baseline >= -tolerance`;orchestrator 据此决定是否退出回路 |
| `append_as` | str | | YAML 段名,默认 `dit_records` |
## 5. 工作流
```
┌──────────────────────────────────────┐
│ 1. 入参校验 │
│ - history_path / practice_path 存在 │
│ - inference_outputs 非空 │
└──────────────┬───────────────────────┘
▼
┌──────────────────────────────────────�
│ 2. 计算 practice.yaml md5 │
└──────────────┬───────────────────────┘
▼
┌──────────────────────────────────────┐
│ 3. 读现有 history.yaml(若有) │
│ - 找 dit_records 段 │
│ - 按 practice_id upsert(替换/追加) │
└──────────────┬───────────────────────┘
▼
┌──────────────────────────────────────┐
│ 4. 写回 history.yaml(保留 LLM 记录) │
└──────────────────────────────────────┘
```
## 6. CLI 调用
```bash
python msagent/skills/quantizer/quant-tuning-history-append-dit/scripts/append.py \
--history-path output/wan22-t2v-a14b-w8a8/history/history.yaml \
--practice-id dit-round-2 \
--practice-path output/wan22-t2v-a14b-w8a8/round_2/practice.yaml \
--inference-outputs \
"output/wan22-t2v-a14b-w8a8/infer_outputs/round_2/overall_consistency/0000.mp4,output/wan22-t2v-a14b-w8a8/infer_outputs/round_2/subject_consistency/0001.mp4"
```
## 7. 输出结果
```msagent-io v1
{
"protocol": "msagent.subagent_io",
"subagent_type": "quant-tuning-history-append-dit",
"status": "ok",
"output": {
"ok": true,
"record": {
"practice_id": "dit-round-2",
"quant_config_md5": "44c42e68...",
"time": "2026-08-08 12:34:56",
"practice_path": "/abs/path/to/round_2/practice.yaml",
"inference_outputs": [
"/abs/path/to/infer_outputs/round_2/overall_consistency/0000.mp4",
"/abs/path/to/infer_outputs/round_2/subject_consistency/0001.mp4"
],
"fp_baseline_outputs": null,
"scores": null,
"overall_score": null,
"loss_vs_baseline": null,
"is_satisfied": null
}
}
}
```
## 8. 错误处理
| 错误 | 处理 |
|---|---|
| `history_path parent not writable` | 立即中止 |
| `practice_path not found` | 立即中止 |
| `inference_outputs 为空` | 立即中止(防止无效 history 记录) |
| YAML 解析失败 | 报 stderr 摘要,立即中止 |
## 9. 约束
- **幂等**:同一 `practice_id` 重复调用覆盖旧记录而非重复追加
- **不破坏 LLM 记录**:仅在 `dit_records` 段追加,与 LLM `records` 段平行
- **不修改既有字段名**:`practice_id` / `quant_config_md5` / `time` 与既有 LLM schema 对齐
- **错误即停**
## 10. 参考
- 输出规范:[output_format.md §3](../../quantization-accuracy-tuning-orchestrator/references/output_format.md)
- 既有 LLM:[quantization-accuracy-tuning-orchestrator/scripts/accuracy_append.py](../../quantization-accuracy-tuning-orchestrator/scripts/accuracy_append.py)
- YAML 工具:[quantization-expert-experience-tuning-rules/scripts/yaml_utils.py](../../quantization-expert-experience-tuning-rules/scripts/yaml_utils.py)
