bot_dev1 42d206e503 feat(#70): 炉层杂质预警特征工程(声明式FeatureSpec引擎,PRD 5.3 ③)
新增 templates/ti-cl4/impurity-forecast:声明式特征工程引擎,特征以
FeatureSpec 描述(EMA/RollingStd/RateOfChange 等 7 算子),换行业只改模板配置
features.template.yaml,引擎零改动(PRD 5.3:特征工程层跨行业差异落在
FeatureSpec,不落代码)。

- features.py:FeatureSpec 声明 + 校验 + 7 算子 + 时序对齐 + 阈值 breach + 零依赖 YAML 解析
- config/features.template.yaml:炉温/氯气/炉压/炉层 9 条特征(对齐点位字典 point_id)
- tests/test_features.py:24 项单测(校验/算子/对齐/breach/配置/端到端提前量)全通过
- _sanity_check.py:冒烟脚本(配置加载 + transform + breach 可观测)

验收:一期阈值+无监督上线,提前量信号可观测(PRD 提前≥30min、误报率≤8%口径)。

# iAOP-Template-Ti 一期 · 炉层杂质预警特征工程模板资产(Issue #70 / PRD 5.3 ③)
#
# 换行业只改本配置,特征引擎(features.py)零改动(PRD 5.3:特征工程层
# 跨行业差异落在 FeatureSpec,不落代码)。
#
# 测点对齐 templates/ti-cl4/point-dict/point_dict.default.csv 的 point_id:
# CLF-01.TEMP 炉温 CLF-01.PRES 炉压
# CLF-01.CL2 氯气流量 CLF-01.CO CO含量
# CLF-01.CO2 CO₂含量 CLF-01.BED 炉层状态
#
# 验收口径(PRD 5.3 ③ / 表验收):炉层杂质预警提前 ≥ 30min,误报率 ≤ 8%。
# 一期阈值 + 无监督上线;阈值参考工艺规范(沸腾氯化炉温 850±50℃,超 900℃
# 触发降流减料),3 个月后转监督再调参。
