- 窗口内(默认 7 天)的输入快照不动:近期 run 仍可能在离线回放里被用到。
- `run_type='organize'` 的行任何窗口都不清:它们的 `input` 存的是 apply 的重放载荷(`src/organize.js` 直接读它重建候选索引),不是可重建的快照。置空会让那次 apply 静默空转并把报告锁死。

## 升格吸收的 evidence(#230 × #275)

`memory_register_document` 注册成功后,这份文档引用的 evidence 行会**在同一事务里**翻成归档(absorbed)。一次吸收 20 条,活跃面就少 20 行——而不是「21 行不是 1 行」。

- 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(#249 的逐字保真池),要归档得手动来;
- 只吸收**原子条**:别的 `document` 行与 `summary` 行不碰——前者本体是磁盘上的文件(归档它会让同一路径下次注册留下第二行),后者是 dream 总览与叙述(按 source 身份去重、按注入档位常驻);
- 想保留活跃面:工具带 `keep_evidence_active: true`(注册器参数是 `archiveEvidence: false`);
- 重注册同一份文档(出新版)时,那些已归档的 evidence 行仍可为**它所属的那份文档**背书;换个文档拿归档 id 当证据,照旧按捏造拒绝。

## 第五指标:归档净增速率 + 可压掉行数

面板「记忆复用」卡与 `GET /api/dsh-mneme/recall-stats` 的返回里多了一个 `archive` 块(#275 拍板:与既有指标同位):

- `total` / `addedInWindow` / `perDay`:归档区现有行数、窗口内新进的、以及日均净增速率。归档时刻取行的 `updated_at`(`setArchived` 会刷它)——代理口径:再改一次已归档行就会被算进本窗口,精确口径要一个 `archived_at` 列(属第二批题材);
- `compressible.rows` / `.groups`:**可压掉行数**——同 type、同 scope、内容归一化后逐字节相同的归档行里,每组留下的那一行之外的那些。判据用内容哈希(与写入准入同一把尺),**不**建在向量近重复上:回收动作本身就会清掉归档行的向量,指标不能指望自己的输入还在。

这是观察口,不是动作触发:真删仍属第二批(未立项)。

## 与 #254 的分界

本入口止体积、不止重复。归档区里同主题条目堆积是**出口**问题,归 #254 的写入准入与后续整理动作面;这里一条记忆都不碰(维护者拍板 4)。

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。

建议修复
             const z = d.zombie || {};
-            const hasData = (d.coverage?.runsScanned ?? 0) > 0 || (z.activeCount ?? 0) > 0;

In `@dsh-mneme/lib/client.js` at line 3674, 更新记忆复用卡片中的 hasData 判断,将
d.archive.total 大于 0 纳入条件;这样即使 runsScanned 和 activeCount 都为 0,只要存在归档数据,组件也会显示卡片。
