- 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

"""Answer scoring for the end-to-end memory harness (single source of truth).
|
||
|
||
Kept dependency-free on purpose so stored runs can be *re-scored offline* without
|
||
loading torch or a 4B checkpoint.
|
||
|
||
Two measurement defects in the original scorer are fixed here; both had produced
|
||
numbers that were wrong enough to misdirect the work:
|
||
|
||
1. **Whitespace-sensitivity.** The containment check was a plain
|
||
``value in reply``, so ``值班人-5259`` scored correct while ``值班人 -5259``
|
||
(one space, same identifier) scored wrong. All 19 such cases were multi-hop,
|
||
which is why multi-hop appeared to be a 24.00% bottleneck when it is in fact
|
||
100.00%. Anchors here are identifiers, versions and names, so the containment
|
||
test now runs on a whitespace-squashed form.
|
||
|
||
2. **Keyword-only refusal detection.** A refusal was recognised only if the
|
||
reply contained one of a fixed list of strings. On the `unknown_attribute`
|
||
category the model refused 12 times out of 25 -- in its own words
|
||
("当前长期记忆中未包含相关信息，无法回答。") -- and *none* of those matched, so
|
||
the unknown-refusal axis read 0.00% instead of 48.00%. Refusal is now
|
||
recognised by pattern.
