背景

#280 讨论里 heptaspirit 指出的失效模式之一:supersede 后检索会不会还引旧值。仓库此前没有专门的回归锁——本 PR 把它钉进 benchmark 与测试套件(StatemenBench anti-update probes 风格)。

改动

  • scripts/benchmark-recall.js:TEST_CASES 支持可选 forbidden 字段——forbidden id 出现在 top-K 即记 forbiddenHit,legacy/fused 与三融合配方全配置判定,CLI 报告加 LEAK 标记;seedService 复刻 applySupersede 的落库状态(loser archived=1 + 正文 superseded-by 注记,无专属取代列)。
  • 新增 test/recall-anti-update.test.js 6 例,锁三件事:
    1. 四路默认检索(keyword/vector/BM25/entity)对归档行是排除不是降权——谁把排除改成降权立刻红;
    2. 取代是归档不是删除(行还在、未遗忘、注记在);
    3. includeArchived 显式口子仍在(排除发生在检索层,不是行消失)。
  • 两条探针用例:常规查询必须返回新值;用旧值措辞的 stale-value 探针查询断言新值命中且旧值 forbidden。

验证

  • 全量 npm test 1198 → 1204,全绿(check-sync 平价);
  • benchmark CLI 两配置 + 三融合配方下探针零 LEAK。

关联

Summary by CodeRabbit

  • 测试
    • 新增反更新回归验证:默认检索会排除已归档的旧决策,同时保留并可检索取代它的新决策。
    • 验证旧决策仍被保留且未被遗忘,并可通过显式归档检索入口查找。
    • 覆盖多种检索方式及融合配置,确保旧决策不会出现在默认检索结果中。
  • 工具
    • 基准报告现会检查已归档旧决策是否进入前 K 条结果;若命中,将标记为“LEAK”并显示泄漏统计。

- TEST_CASES 支持可选 forbidden 字段,legacy/fused/三融合配方全配置判定 forbiddenHit,CLI 报告加 LEAK 标记
- seedService 复刻 applySupersede 落库状态(loser archived=1 + superseded-by 注记)
- 新增 test/recall-anti-update.test.js 6 例:四路默认检索对归档行是排除不是降权;取代是归档不是删除;includeArchived 显式口子仍在
- 依据 StatemenBench anti-update probes;测试 1198 → 1204,全量 npm test 绿

📝 Walkthrough

Walkthrough

基准测试现在检查已归档的旧决策是否进入 top-K,并在命中时记录泄漏。新增回归测试覆盖不同检索模式、融合配置、旧记忆归档状态及显式归档检索入口。

Changes

Anti-update 检索回归

Layer / File(s) Summary
基准探针与泄漏统计
dsh-mneme/scripts/benchmark-recall.js, dsh-mneme/CHANGELOG.md
新增要求命中新 Rust 决策、禁止旧 Go 决策进入结果的基准探针。seed 添加已归档的旧决策。常规基准和融合配方统计禁止 ID 命中,并在报告中标记和汇总泄漏。
检索与归档回归测试
dsh-mneme/test/recall-anti-update.test.js
新增测试,检查基准与融合结果、keyword/vector/auto 检索、BM25 候选池、旧记忆归档状态,以及默认检索与 includeArchived: true 的差异。

Merge Risk: 🔵 Low · up to c832e

The current probes cover the intended configurations, but the regression test would not catch their accidental removal. This is a bounded test-coverage risk that can be addressed as a follow-up.

为每个融合配方断言反更新探针仍然存在。

benchmark.test.js 已断言 blend、rrf、minmax 三个配方,因此缺少配方时相关测试会失败。无需在此测试中重复断言配方名称。

但是,当前测试会跳过没有 forbidden 的行。如果所有反更新探针从 TEST_CASES 中删除,或结果行不再携带 forbidden,测试仍可能通过。请为每个配方断言预期的反更新探针数量。

建议的测试修改
   const report = await runFusionBenchmark({ topK: 5 });
   for (const run of report.runs) {
-    for (const r of run.rows) {
-      if (!r.forbidden?.length) continue;
+    const probes = run.rows.filter((r) => r.forbidden?.length);
+    assert.equal(probes.length, 2, `${run.config}: anti-update probes present`);
+    for (const r of probes) {
       assert.equal(r.forbiddenHit, 0, `${run.config} "${r.query}": leaked via fusion recipe`);
     }
   }

Update the test around `runFusionBenchmark` to assert that each run contains the
expected two rows with nonempty `forbidden` probes before checking
`forbiddenHit`. Keep the existing per-probe leak assertions and rely on the
separate benchmark test for recipe-name coverage.
