你 09-28 拍的那条:A2 判据模块由本侧来写。这一批就是它,闸门侧一行没动。

这一批做了什么

  • 新增 src/sensitive-scan.js:纯确定性、零 LLM。判据独立成文件而不是塞进 write-admission.js,判据的归属是 聊几个我觉得值得做的方向 #164 A2、闸门的归属是 [Feature] 写入准入(non-write 判定):把「这条该不该进库」前移到 LLM 之前 #254,换判据只换 index.js 里注入的那一行。写入边界的另外两个出口(autoSummarize / dream 输出)要复用时直接 import scanSensitive。
  • 审计位按你定的形状没动:命中落 metadata.deny.reason='sensitive' + kind/label,enforced 由 decision 推出。#332 里那个占位的 sensitiveScan 注入点现在接到了真判据。
  • 假阳率按你 09-28 的口径由那 12 条负样本定:test/write-admission-samples.js 的 26 条语料原样跑真判据(不是参考实现),正样本不漏、负样本一条不误杀。参考实现 referenceScan 留在原地只服务闸门测,本批没删(按你说的,同语料跑过真判据之后再删。
  • 判据自己的闸是顶层键 sensitiveScanEnabled,默认关;开启后最狠也只是「仅告警」:命中留审计、写入照常。真拦仍要 writeAdmission.enabled + writeAdmission.enforce(聊几个我觉得值得做的方向 #164 口径:默认仅告警、拦截 opt-in),判据不碰决策。新键三处成对(config.js 白名单 + settings.js + lib/client.js 双语文案)并进位到 /features effective,计数锁 +1。

一处需要你拍板的口径

我把 A2 的激活做成了独立键,而不是挂在 writeAdmission.enabled 底下。 理由:那一个管的是第 1 级的空白 / 噪声判据,本键管密钥 / PII,两批的误杀面差一个量级(空白 / 噪声没有解释空间;邮箱 / 手机号在项目记忆里完全可能是正当内容),绑在同一个开关上就没法单独观察 A2 的命中分布,而按类看分布正是 kind 落审计的用途。

如果你更想看到「打开写入准入 = 两批判据一起跑」的形态,说一句我就把它折成 writeAdmission.enabled 的子行为,能省一个键。

探针里发现并修的一处漏放

语料之外我另跑了一组形状,发现 AWS 的 secret access key 两条规则都够不着:它没有前缀,而通用那条要求 secret 关键词后面紧跟赋值号,多词键 AWS_SECRET_ACCESS_KEY= 不满足。补了专用的键名规则(40 位下限),并把它与「赋值型那条不看值的形状」一起锁进测试。

没做的

  • autoSummarize / dream 输出的接线不在本批。你把这条列为同一个 issue 的第二批,我就没顺手带上,这也是本 PR 没有 Closes #254 的原因,等你认领或指派。
  • PII 这一档我按「先看得见分布」处理,没有按类放行。邮箱 / 手机号的命中在正常记忆里会出现,所以 kind 一并落审计;要不要按 kind 放行、放行哪几类,等分布出来你定。

测试与闸门

  • 全量:1512 tests / 1511 pass / 0 fail / 1 skip(skip 是既有的环境项)。
  • 新增 test/sensitive-scan.test.js 10 条:26 条语料原样跑真判据、kind 与语料声明一致、只扫文本字段不扫元数据、tags 也扫、工厂关时不返回函数、返回值不含决策字段、坏输入不抛、一处命中只报最严重那条、语料外探针各一条。
  • test/write-admission.test.js 增 5 条:用真 Config 装配,钉住三层开关语义(默认关 / 观察档 / 拦截档)与「只开 A2 不会把空白写入拦下」。
  • check-sync 一致;pre-review 对新文件与改动文件 0 告警(仓内存量告警未动)。
  • 推之前被 GitHub push protection 拦了一次(sk_live_ 字面量),测试改成复用语料 helper 的拼接值,仓库文本里不留完整凭据形状,这条也写进测试文件头了。

CI 抓出来的一条(已修)

第一轮 CI:Node 24 全绿,Node 22 两个平台红,6 个测试文件同一个根因:

SyntaxError: Invalid regular expression: /(?i:aws[_-]?secret[_-]?access[_-]?key).../: Invalid group

aws_secret_key 那条规则我用了行内修饰符组 (?i:...),那是 ES2025 语法,Node 22 的 V8 不认。改成在整条规则上挂 /i:键名那一半照旧不分大小写,而 \s、[:=]、["']、[A-Za-z0-9/+=] 本来就不分大小写,两者语义等价。本文件其余规则也没有用行内修饰符组的。

教训:我本机是 Node 26,engines 字段又是空的,本地跑绿不代表矩阵绿,CI 里的 22 是唯一把关点。

Summary by CodeRabbit

  • 新功能
    • 新增可选的密钥与个人信息扫描开关,默认关闭。扫描范围包括记忆内容及标签,可识别多类凭据、邮箱、手机号、身份证号和银行卡号。
    • 开启扫描后,命中内容会记录审计信息;同时启用写入拦截时,命中内容将被拒绝写入。
  • 测试
    • 增加扫描规则、配置开关及审计与拦截行为的验证。

Merge Risk: 🔵 Low · up to 8e286

The new secret/PII scan is off by default and does not change existing write behavior. The setting's text suggests that enabling the scan alone will audit hits, but write admission must also be enabled. Fix the wording, or decouple the scan from write admission, before or soon after merge.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 8e286

The new scanning switch does not independently activate the observation mode described to users. Another admission switch must also be enabled, so operators can believe sensitive-content detection is running when it is not. Exposure is bounded by default-off settings, classification-only audit output, and rejection before storage on covered writes.

Retained concerns

  • Medium · security · observed: The new sensitiveScanEnabled switch is presented as an independent observation control, but it cannot activate classification while the default-off writeAdmission.enabled switch remains off. Such writes receive no sensitive classification or sensitive-hit audit, despite the scanner being configured on. This is a newly introduced activation-contract mismatch, not evidence that previously protected secrets became exposed.
Security review details

Security Blast Radius

  • observed — The inspected input boundary is the memory-save tool, which forwards caller-supplied title, content and tags with host-derived session identity. The persistence sink is the package's memory store, followed by its existing synchronization, notification and embedding pipeline. Dedupe targets must match the existing agent, workspace and sensitivity scope keys.

Security Findings and Attack Paths

  • observed — Enabling only the new scanning flag constructs a classifier but leaves it uncalled because writeAdmission.enabled defaults off. The advertised independent observation rollout therefore produces no sensitive-hit classification. The integration test's successful observation case explicitly enables both flags.
  • observed — A memory-save call matching an existing title, type and scope can append sensitive content through the merge branch before admission is reached. Direct updates also do not invoke admission. These paths and their exposure are unchanged from base, so they are limitations of the new control's coverage, not newly introduced bypass privileges.

Trust Boundaries and Controls

  • observed — Admission participation requires session identity and llmAudit not being disabled. No-session system producers return before classification; autoSummarize and dream integration is explicitly deferred by this PR. The new scanner is consequently not a universal storage-boundary policy.
  • observed — For covered writes, sensitive classification precedes the pinned-memory budget exemption. Pinned memory types therefore do not exempt a successfully detected credential from enabled enforcement.

Resilience and Maintainability Implications

  • observed — Rejected writes do not advance the admission topic table. Allowed writes advance it only after an audit row is successfully stored and when not exempt. These inherited ordering rules avoid treating denied writes or failed audit records as successful admission history.

Hardening Proposals

  • proposed — Make the activation contract explicit: either permit sensitive observation independently of the blank/noise gate, or expose its required parent controls and pending-restart state so a configured flag cannot be mistaken for active detection.
  • proposed — If the intended policy becomes protection of all persisted sensitive content, extend classification to merge and update transitions and explicitly define system-producer and failure-policy exceptions. This would strengthen inherited gaps rather than remediate a demonstrated exposure regression.

CI 第一轮 Node 22 两平台红,Node 24 全绿。根因是 sensitive-scan.js 里 aws_secret_key 那条规则用了行内修饰符组 (?i:...)——ES2025 语法,Node 22 的 V8 抛 SyntaxError: Invalid group,连带 6 个 import 它的测试文件全红。

改成整条挂 /i(键名那半照旧不分大小写,其余部分本来就不分大小写,语义等价),已 force-push:83cc8ca → 7aa61f6。改动只有 src/sensitive-scan.js 与 sync 出来的 lib/sensitive-scan.js,其余 13 个文件一字未动。

我本机是 Node 26,package.json 又没有 engines,本地跑绿骗过了我一次。

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

sensitiveScanEnabled 的文档与面板文案漏写了 writeAdmission.enabled 前提。

evaluate 只在 writeAdmission.enabled === true 时调用 sensitiveScan。因此,只打开 sensitiveScanEnabled 时,扫描器不运行,也不写入审计。test/write-admission.test.js 第 621-627 行的用例证实了这一行为。下面三个位置的说明与这一行为不一致:

  • dsh-mneme/src/config.js#L660-L667:在组合矩阵中加入 writeAdmission.enabled 前提;同时修正 src/sensitive-scan.js 第 158 行“不是子开关”的说法。如果设计意图是本键独立生效,就修改 evaluate。
  • dsh-mneme/lib/client.js#L498-L499:在中文提示中写明本开关需要同时打开“写入准入判定”才会扫描。
  • dsh-mneme/lib/client.js#L935-L936:在英文提示中写明本开关需要同时打开 write admission checks 才会扫描。

认了:该修的是描述,不是行为。三处都改了。

核实:evaluate 只在 writeAdmission.enabled === true 时走 firstLevelHit,而 sensitiveScan 只从 firstLevelHit 里被调用。所以单开 sensitiveScanEnabled 确实既不扫也不写 deny 审计。它是第 1 级闸门内的一批判据,不是能独立跑的链路。

改动(commit 8dc2a59):

  • dsh-mneme/src/config.js:654-670:组合矩阵重写成四行,第一行是「writeAdmission.enabled 关 → 第 1 级整个不跑,本键开也没用」,并写明单开本键 = 零行为变化。
  • dsh-mneme/src/sensitive-scan.js:156-162:删掉「不是 writeAdmission.enabled 的子开关」那半句(会被读成能独立生效),换成「闸门」与「闸门内这一批判据」的分层陈述。
  • dsh-mneme/lib/client.js:496-500(中文)与 dsh-mneme/lib/client.js:932-938(英文):面板提示补「需先打开写入准入判定才会执行」。
  • dsh-mneme/test/write-admission.test.js:634-645:新增一条用例钉住这个前提(只开本键时写入照常落库、没有任何 deny 审计);原来那两条互不依赖用例保留。

全量 1513 tests / 1512 pass / 0 fail / 1 skip。

evaluate 按你的建议没动。若维护者更想要「单开本键就扫」的语义,要改的是 dsh-mneme/src/write-admission.js 的调用点(把 sensitiveScan 挪出 writeAdmission.enabled 分支),代价是审计行的来源不再唯一。这个归属留给维护者。

…1 级)

判据独立成 src/sensitive-scan.js:纯确定性、零 LLM,先认形状再认关键词。写入准入
(slow-stack#332 就留好的 sensitiveScan 注入点)从此拿到真判据,审计位不变
(metadata.deny.reason='sensitive' + kind/label)。

自己的闸是顶层键 sensitiveScanEnabled(默认关):与 writeAdmission.enabled 分开,
两批判据的误杀面差一个量级,绑一个开关上就没法单独看 A2 的命中分布。命中之后是仅
告警还是真拦仍由 enforce 决定(slow-stack#164 口径:默认仅告警、拦截 opt-in),判据不碰决策。

分层要写清:判据的唯一调用点在写入准入的 firstLevelHit,闸门不开第 1 级就没人来调
扫描器,所以单开本键是零行为变化。配置注释里的组合矩阵、面板中英文案与一条新用例
都按这条改(原稿把矩阵写成了能独立生效,CodeRabbit 在 PR slow-stack#354 上指出)。

假阳率按 09-28 的口径由那 12 条负样本定:26 条语料原样跑,正样本不漏、负样本不误杀。
实现期额外探针另修了一处漏放(AWS secret access key 无前缀,多词键够不着关键词规则)。

CodeRabbit 那条 sensitiveScanEnabled 的发现是真缺陷,已修(commit 8dc2a59)。

行为没动:判据的唯一调用点在 dsh-mneme/src/write-admission.js 的 firstLevelHit,而闸门要 writeAdmission.enabled 打开才走第 1 级,所以单开 sensitiveScanEnabled 就是零行为变化。原稿把这一点写成了能独立生效,位置有三处:dsh-mneme/src/config.js:654-670 的组合矩阵、dsh-mneme/src/sensitive-scan.js:156-162 的说明、dsh-mneme/lib/client.js:496-500 与 :932-938 的中英文案。三处都按实际分层改了,并新增一条用例(dsh-mneme/test/write-admission.test.js:634-645)钉住这个前提。

评审通过,可以合。分层验收都复核过:闸门契约(firstLevelHit 消费 {kind,label}、异常兜底、enabled 才跑第 1 级)、默认关逐字段等价、26 条语料原样跑真判据、三层开关语义、旗标锁 +1、check-sync,均确认。Node 22 的 (?i:…) 修复确认与原语义等价。

口径拍板:保持独立键,不折。理由同你写的:两批判据误杀面差一个量级,绑死就没法单独观察 A2 命中分布——这正是 kind 落审计的用途;折成子行为省一个键,赔掉的是按类看分布的观察位。

两条备忘(都不拦本批):① assigned_secret 守卫没盖 {{...}} 无空格模板与 %VAR%(password: {{secrets.DSH}} 会命中),观察档下只是多一行审计,等分布出来再定;② CodeRabbit 提到的 merge/直改路径不过准入是 #332 既有覆盖面,记进 #254 第二批一起处理。

另:与 #355 的 [Unreleased] 撞同一位置,后合的一条会需要 rebase。

* fix(scope): strictScope 硬过滤补到 entity: / attr: 两条前缀路

searchMemories 里这两条前缀路在**函数入口**就 return,而 strictScope 硬过滤写在函数
**后半段**的融合池上——早返回的路根本走不到,于是显式标注为他者 scope 的记忆换这两个
前缀就能原样读出,而且没有 A2 的 ×0.5 降权(满分返回)。暴露面是 scopeEnabled +
strictScope + entitySearchEnabled 三者同开(默认全关),而 entity: 正是 #24 图谱线在推
的语法,这条路的使用面只会越来越大。

修法:scope 闸抽成 gateByScope() 单一实现,融合池与两条前缀路三处共用,让「过滤点写在
哪」不再漂移(同 #349 把阈值口径收进 activeStoreSize() 的理由)。searchByEntity /
searchByAttr 从 options 里取 scope——调用方原本就把 options 整个传了进来,只是这两个
函数只解构了 topK,scope 被丢掉。

闸门必须在 touchRecalled **之前**:只加在「返回前」的话,一次越权检索照样会给出局的行
刷回温时钟,并在被动确认开启时 bump 它们的关联边——命中反馈落到了调用方本不该看见的
行上。

strictScope 关(默认)时 gateByScope 原样返回,行为逐字节不变。他 scope 行的 A2 软加权
要不要一并补到这两条路,按 #339 的口径另行决定,本批不碰排序语义。

测试三条:entity: 路与 attr: 路各一条(显式他者出局、auto / 存量他者按 A2 保留、原主人
仍看得见显式那条——最后一条是防止「谁都搜不到」的假绿),加一条次序锁(出局行不被回温、
不 bump 关联边,并带可见行的正向对照)。变异检验:去掉任一条路的闸门、或把闸门挪到
touch 之后,对应用例各自变红。

* docs(changelog): 记录 strictScope 前缀路绕过的修复;badge:sync 对齐双 README 计数

双 README 的测试数此前停在 1497(#354 / #355 合并时遗留的漂移),#356 合入后是 1519,
本批再加 3 条用例,统一用仓库自己的 npm run badge:sync 刷到 1522(6 处),不手改。

CHANGELOG 与 #356 在同一处([Unreleased] 的 🐛 修复 段)撞车,按上次 #354/#355 的处置
把两条条目并入同一个段,不新开一节。

* fix(scope): scope 闸先于 topK 截断(评审发现:出局候选会占掉名额)

先 slice 再 filter 的话,排在前面那条被闸掉的候选会占住槽位——topK=1 且首位出局时直接
返回空数组,明明还有可见匹配。改成先过闸再截断,与融合池那条路同序(那边也是先 filter
后 slice)。

searchByEntity 的关键词路窗口同时取 topK 的两倍:闸门在截断之前生效,窗口按最终条数取就
会不够(与融合路给向量检索取 lim * 2 同一个理由)。没有候选被闸掉时结果逐字节不变——
多出来的是排在后面的低分候选,进不了 topK。

新增一条用例用 topK=1 把次序钉死;变异检验:把两条路各自改回「先截断后过滤」,该用例
分别变红。README 计数随新增用例由 badge:sync 刷到 1523。

- 版本号 0.8.12 → 0.8.13(dsh-mneme/package.json + package-lock.json 两处)
- 双 README 测试数 → 1523(本轮全量实测),走 badge:sync
- CHANGELOG 的 [Unreleased] 承接为 [0.8.13] - 2026-10-03;四条条目补 PR 号,并补
  🧹 工程 与 ### 贡献者 / Thanks(@heptaspirit,PR #354 / #355)

CHANGELOG 小节是人工补的:scripts/release-prep.mjs 在 CRLF 检出上用 /^(# Changelog\n\n)/
匹配文件头,命中不了就退化成空操作(脚本仍打印 ✓),CI 在 ubuntu 上是 LF 所以未暴露;
它第 4 步的 README 版本表占位行也已是死代码(两张表不存在)。

按 CONTRIBUTING 的流程:合并本 PR 后先在本机 npm publish(2FA),再推 v0.8.13 tag——
顺序反了 release.yml 的 publish 步会真发一次并因 2FA 失败。
