WpyQwq 643e22ecb9 Natural Memory NM2.1: 记忆路由器分叉、数据集缺陷修复与全轴评测证据
- 引入 MemoryRouterXL 与 v5/v6 流式多线程训练/编码管线
- 修复 prepare_memory_router_dataset 候选池重建缺陷(mega 家族 3568x 加速,输出逐字节相同)
- 修复 v5 被破坏的拒答与多跳标签(train 未知样本 319 -> 16319,multi_hop 平均正例 1.00 -> 2.00)
- 同存储预算下 V2-128 v6 逐轴 22/22 通过:Top-1 41.12% -> 94.62%,未知拒答 0.00% -> 100.00%
- 记录三条被实测推翻的显然优化(logits_to_keep=1 反而慢 55%、XL 容量未带来收益)
- 记忆手术跨架构可移植性 14/14,读写关闭时与原生模型逐位相同

"""Normalize conversation logs into a leak-resistant memory-policy dataset.
The runtime accepts many local data shapes because real users rarely keep
their chat exports in one format. This command converts them to a small,
auditable JSONL schema without inventing labels. It understands the current
``native_memory`` episode format, the streaming demo format, and a generic
format documented in the output manifest.
The bundled fallback files are bootstrap data for smoke tests. A real user
corpus can be supplied with ``--source``/``--eval-source`` and receives the
same normalization and group-level split guarantees.
