- Line 7: Correct the changelog entry to reflect that sensitive scanning is not
currently implemented or wired into production: remove claims that
`sensitiveScanEnabled`, `src/sensitive-scan.js`, and sensitive-hit auditing are
available, and describe the current injection-point status instead. Do not imply
that `writeAdmission.enabled` alone enables scanning; if documenting future
behavior, state that scanning requires both an injected scanner and
`writeAdmission.enabled`, while `writeAdmission.enforce` controls whether a hit
blocks the write.
Review comments at @dsh-mneme/src/guide.js:
- Around line 47-51: Update the `memory_save` guidance to avoid promising that
explicit scopes isolate memories across all searches. Clarify that `strictScope`
hides out-of-scope memories in normal retrieval when enabled, while `entity:`
and `attr:` searches bypass that filter and normal retrieval may still return
scoped memories when `strictScope` is disabled.

更正敏感扫描的实现状态和启用条件。
当前代码没有 sensitiveScanEnabled、src/sensitive-scan.js，也没有生产环境的 sensitiveScan 注入。index.js 创建 writeAdmission 时未传入扫描器，因此即使启用 writeAdmission.enabled，firstLevelHit() 也只会执行空白和噪声判据，不会记录敏感命中。
如果后续接入扫描器，必须同时启用 writeAdmission.enabled；writeAdmission.enforce 只控制命中后是否拦截写入。当前 changelog 不应声明敏感扫描已实现，应先完成扫描器和配置接线，或改为记录当前仅提供注入点的状态。

不要承诺显式 scope 在所有检索中隔离。
公开的 memory_search 会把查询传给 service.searchMemories。当 entitySearchEnabled 开启时，entity: 和 attr: 查询会绕过 isVisibleInScope。当 strictScope 关闭时，普通检索也只降权，不会隐藏越界记录。因此，其他 workspace 或 agent 仍可读取显式 scoped memory，当前说明会造成错误的隐私预期。

按代码核过，成立，已改。这里不回放全部依据，只记一条结果：拟句的错误在于「默认配置下的行为」而不是「隔离本身」——strictScope 默认 false（config.js:732），他 scope 是 SCOPE_FOREIGN_PENALTY = 0.5 降权保留可见（service.js:938），硬过滤还要额外满足 *_scope_source === 'explicit'。工具描述现已改成 An unscoped memory is visible everywhere; a scoped one is filtered or downranked outside its scope.，并用测试反向锁住。
没有直接套用建议里的替换文本：它把 strictScope / entitySearchEnabled 这类配置键写进工具描述，而这段文字每次调用都进上下文，承载的是给模型的判断规则而不是实现说明。依据与相邻发现（entity: / attr: 前缀绕过 strictScope）写在 PR 评论里。
TOOL_GUIDE.memory_save 此前只讲「该不该写」，没讲「写给谁看」。补一句判断规则：只在 记忆只对某个 workspace/agent 成立时才声明 workspace_scope / agent_scope，否则两个 都别填；未标注的处处可见，标了 scope 的离开他 scope 时降权或过滤。 措辞按实际行为写：A2 软隔离是他 scope 降权 x0.5 但保留可见，只有 A3 strictScope （默认关）才硬过滤。初稿里的「静默消失」与默认配置下的行为不符，也与「拒绝可解释、 不静默丢弃」的口径（slow-stack#254 验收第 2 条）冲突，已改为 filtered or downranked；测试除 原有两条断言外，另加一条反向锁：描述里不得出现 silently disappears。 落在工具描述而不是总则：它是单工具的判据，总则那五条讲的是「何时查 / 何时写 / 何时 no-op」，加第六条会把单工具语义抬成全局纪律。测试同时锁两件事——这句话在 工具描述里、且不落在总则段。

两条都成立，都已改。这条 PR 现在 head 是 1. 没错，而且比「写得不准确」更严重：这条分支上根本没有 2. 也成立，按代码核过三处：
所以拟句里的 改成： 没采用建议里的替换文本：那段把 3. 相邻发现（不在这条 PR 范围里，未动） 顺着第 2 条查的时候确认了一个既有缺口： 这是 A3（issue #17）的既有行为，不属于这条 PR，我没动。需要的话我另开一条 issue 记录。 测试读数：这条分支 1498 / 1497 pass / 0 fail / 1 skip；#354 那条 1512 / 1511 pass / 0 fail / 1 skip。 |

评审通过。文案与实现对过：A2 软隔离确是 foreign ×0.5 保留可见，strictScope 默认关，「filtered or downranked」没有夸大；措辞回归锁（不许 "silently disappears"、不进总则）钉得也对。
一处措辞小扣，改不改都行：CHANGELOG 与注释里「scope 参数是必填面」容易读成 schema 必填——工具描述里两个参数标的是 Optional，新指引也让 "otherwise leave both out"。建议换成「常驻决策面」这类说法。

区分省略参数与最终未标注记录。
scopeEnabled 和 strictScope 的默认值都是 false。在默认配置下，省略两个参数会保留为未标注记录，并且处处可见。
当 scopeEnabled 开启且会话 scope 可解析时，省略参数会由 memory_save.execute 自动填入会话 scope。该记录不是未标注记录。在其他 scope 下，自动标注记录可能被降权；显式标注的记录还可能被过滤。
当前两句没有说明这个条件。请在 dsh-mneme/src/guide.js 和同步文件 dsh-mneme/lib/guide.js 中明确区分省略参数与最终未标注记录。

…358) * 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。

#249 第二批里最便宜的一件：能力说明此前没提
scope。memory_save的 scope 参数是必填面，漏填的后果是单向的，这一批只补这一句。改了什么
TOOL_GUIDE.memory_save追加一句判断规则（英文正本，落在工具描述尾部，injectGuidanceEnabled开启时生效）。英文原文见src/guide.js；大意：只在记忆只对某个 workspace / agent 成立时才声明workspace_scope/agent_scope，否则两个都别填，未标注的处处可见、收窄过的会在别处静默消失。字面就是我在 #249 评论里拟的那句，两处小改后定稿。写进工具描述而不是总则：它是单工具的判据，总则那五条讲的是「何时查 / 何时写 / 何时 no-op」，加第六条会把单工具语义抬成全局纪律。测试同时锁两件事，这句话在工具描述里、且不出现在总则段。
后半句（默认两个都别填）不是凑字数：只写「什么时候该填」会把模型推向「能填就填」，而收窄一条本该全局可见的记忆，损失是静默的。把默认方向也写出来，这句才构成一条可执行的判断规则。
