在仅有归档数据时显示“记忆复用”卡片。
当 d.archive.total > 0 且 z.activeCount 与 d.coverage.runsScanned 都为 0 时，hasData 为 false。组件会返回 null，所以文档要求显示的归档指标不会出现。此情况仅影响归档指标的可见性，建议降为小问题。

dup 信号把遗忘区命中记成活区命中。 lookupContentDup 只返回 archived。候选中只剩已遗忘但未归档的行时，审计写成 archived: false。forgotten 行不在 saveWithDedupe 的候选集内，这类命中也是穿透，现在却被当成"去重候选集本该拦住"。
dsh-mneme/src/write-admission.js#L157-L158：在返回的dup中加上forgotten: hit.forgotten === true，并在record的 metadata 中写入forgotten。dsh-mneme/lib/write-admission.js#L157-L158：src改完后执行npm run sync，同步相同的修改。

拍板 5 与第五指标的实现侧条目： 1. registerDocument 成功后，同一事务把被吸收的 evidence 行翻归档（只翻标志位，内容 与审计全留，可恢复）：constraint/preference 永不自动归档；document 与 summary 两类不吸收（各有自己的生命周期，归档它们会让同一路径或同源总览多出一行）； opt-out 走 keep_evidence_active 或 archiveEvidence:false。 2. 重注册同一份文档时，被它自己吸收过的已归档 id 仍算它的 evidence，不会被捏造判据 误报；别的文档引用这些 id 照旧拒绝。 3. recall-stats 新增 archive 块：归档净增速率（total/addedInWindow/perDay）与可压掉 行数（同 type 同 scope 的内容哈希精确重复）；面板「记忆复用」卡与 STORAGE.md 同步。 已知近似写在 recall-stats.js 文件头与 STORAGE.md：归档时刻取 updated_at，精确口径要 archived_at 列，属第二批题材。

拍板 5 与第五指标这两条的实现侧条目，都在这批。
叠在 #311 上（#254 那一批）：这批的第五指标读它落的
content_hash列。先合 #311，这里的 diff 会自动收窄到本单的部分。拍板 5：升格吸收的 evidence 随之归档
registerDocument成功后，同一事务把被吸收的 evidence 行翻归档。只翻标志位：内容、content_history、审计行一条不删，随时可以还原。constraint/preference永不自动归档。这个集合由service.js注入（PINNED_MEMORY_TYPES），src/document.js里不 import 它，否则 service 与 document 成环。document与summary。这两类各有自己的生命周期，归档它们会各自留下第二行：document 行是磁盘文件的指针，而 supersede 探测只看活跃行（store.list默认排除归档），归档它之后，同一路径下次注册会在旧行还挂着「新版本」语义时再铸一行，指针注记与content_history记账也走不到；summary（dream 总览与叙述）按 source 身份去重、按注入档位常驻，归档它会让下一次做梦把它当不存在而重铸一行。archiveEvidence: false，工具面是keep_evidence_active: true。返回值与工具输出都带evidence_archived计数。第五指标：归档净增速率 + 可压掉行数
recall-stats返回里多了archive块，与既有指标同位；面板「记忆复用」卡与GET /api/dsh-mneme/recall-stats都能看到。total/addedInWindow/perDay：归档区现有行数、窗口内新进的、日均净增速率。compressible.rows/.groups：可压掉行数。判据是同 type、同 scope 三维、内容哈希完全相同的归档行里每组多出来的那些。clearArchivedEmbeddings），指标不能建在自己的输入会被回收掉的数据上。配了一条用例：清完向量后读数不变。两处交底
updated_at是代理口径（setArchived会刷它）。对已归档行再做一次memory_update，或对同一行重复setArchived(…, true)，都会被算进本窗口，perDay因此偏高。精确口径要一个archived_at列，属第二批题材。recall-stats.js文件头与docs/STORAGE.md都写明了。测试与闸门
npm test：1366 tests / 1365 pass / 0 fail（本批新增 10 条）。test/document.test.js增六条：吸收归档与 pinned 豁免、opt-out、重注册认回且别的文档引用仍拒、没有 pinned 集合时整步跳过（fail-safe）、document 行与 summary 行不被吸收。test/recall-stats.test.js增四条：净增速率（窗外归档只进总数）、可压掉行数（跨 scope 与活跃行不算）、清向量后不变、空归档给 0。check-sync：src 与 lib 一致（48 文件）。lib/client.js没有 src 对应物，是手写文件，双语文案两处都补了。src/content-hash.js口径说明（其中一条属 feat(admission): 内容哈希计量与归档行纳入去重候选集（#254） #311 那批）。代码层面修掉的两条在旧代码下红过；文案与口径说明这两处没有回归可钉，就交底在这里。Summary by CodeRabbit
