'''``common/Utils.py`` — Phase 3 拆分后的兼容层。

按 ARCHITECTURE.md Phase 3 拆分建议，原 ``common/Utils.py`` 中的函数和全局
变量已按职责迁移到以下 7 个目标模块：

| 目标文件 | 迁出内容 | 类型 |
|---|---|---|
| ``common/json_encoder.py`` | ``MyEncoder`` | RULE FRAMEWORK |
| ``model_runtime/viterbi.py`` | ``viterbi_decode`` | CORE |
| ``model_runtime/vocab.py`` | ``vocab_word``、char/id 映射等 | CORE |
| ``model_runtime/embed.py`` | w2v 加载、``embedding`` 等 | CORE |
| ``services/external_inference/paieas.py`` | PAI-EAS 客户端 | INFRA |
| ``common/context_utils.py`` | 上下文窗口、金额标准化等纯函数 | CORE |
| ``common/logging.py`` | ``log`` / ``debug`` / ``logger`` | INFRA |

本文件通过 re-export 保持全部旧 import 路径可用：
    ``from BiddingKG.dl.common.Utils import viterbi_decode``  仍然有效
    ``from BiddingKG.dl.common.Utils import log``            仍然有效
    ``from BiddingKG.dl.common.Utils import *``             仍然有效

未迁移的函数（时间处理、keras metrics、HTML 工具、pickle save/load、
encodeInput 等）仍保留在本文件中，后续 Phase 再拆。
