Closes #591

改了什么

把 pin 从「类型推断」改成「用户亲手钉的显式事实」，并修掉同一链上的三处缺陷。

默认 pinnedInjectBudget = 0，预算关时注入序列与改前逐条相同 —— 这条线不改变任何人的现有行为。

1. pin 池不再被向量路合并的封顶挤出候选池

pin 筛选发生在 hybrid 合并之后，而 merged 已按 poolSize 封顶（生产 maxItems=5 → poolSize=10，向量路一次正好返回 10 条即 break）。规则窗口里的 constraint/preference 因此一条都进不了 candidates，pin 池只能从那 10 条里碰运气选。

修法：合并块之后、topic 重排之前，把被 poolSize 挤掉的 pin 类行补到候选池尾部。两条纪律：只在预算 > 0 时补（预算关时 candidates 与改前一致）；只补尾部，strictScope 与 scopeState 两道闸门照旧作用其上。

真库副本实测（6733 条有向量行、同一 query、1024 维、pinnedInjectBudget=5、maxItems=5）：

臂	pin 注入	注入总条数
改前	2/5	7
改后	5/5	10

无向量路径改前改后都 5/5、10 条且逐条同序 —— 补丁不改本来正常的路径。前 5 位新进的三条是「反对 AI 赋魅」「第三方个人信息不该长期保存」「拒绝谄媚」，原有条目只后移，无一条被挤出注入块。

2. 判据从「表里有几行」改成「有几条能用的」

上一版判据是 countPinned() > 0。这条判据是错的：pin 行会在 memories 那边被归档、遗忘、硬删，而 pinned_memories 对这三种一无所知。只要表里还剩一行（哪怕早已归档），判据就一直判 explicit，于是 eligible 恒为空 —— pin 全灭，且永不回落到旧的类型口径，无日志无报错。

四场景复现：正常 pin 不触发；setArchived 触发；setForget 触发；remove 触发。前两种最要紧，因为归档/遗忘是日常操作，比硬删常见得多 —— 所以只补 DELETE 堵不住，根因在判据。

pinnedStats.source 因此有三档：explicit / fallback-none-usable（钉过但一条都用不了，静默降级必须留痕）/ type-fallback（从没钉过，升级即等价）。

为什么「还有一条能用就留在 explicit」而不是整段回落：若因为「有 3 条归档」就回落类型口径，会突然冒出一批她根本没钉过的条目，那比少注入更糟。

3. `memory_pin` 的 `injectable` 回执补上「暂停作用域」

描述文案、README 与 render 文案三处都写着「遗忘 / 归档 / 暂停作用域都优先于 pin，回执如实报告」，但 execute 只算了两项：

const injectable = !target.forgotten && !target.archived;

被按下作用域（enforce 档）的行因此报 injectable: true 而实际一条都没注入。三组对照：按下暂停 → 回执 true、注入 0 条；不按暂停 → 回执 true、注入 1 条；暂停中钉、解除后重钉 → 两次都 true。报 true 的两种处境里一种真会注入、一种被挡住，回执分不出来。

改法：回执改用 service.filterPaused([target])（即 scopeStateGate.filter），与注入侧共用同一个出口，以后改闸不会漏掉回执这一侧。注入侧本身没坏 —— scopeStateGate 一直在拦，坏的是回执另写了一份判据。

落点

src/store.js：新增 pinned_memories(memory_id PRIMARY KEY, created_at, note) + idx_pinned_created。独立表而非主表布尔列 —— 回退只需一条 DROP，不碰主表 31 列；pin 是「用户与记忆之间的一条关系」，created_at 还能给出 pin 顺序。幂等靠 CREATE TABLE IF NOT EXISTS，不登记 applied_migrations（本表没有回填步骤）。外泄面为零：mirror / share 都不 SELECT 本表。
src/service.js：取数按 id 点查（pin 行可能不在 200 行候选窗口内），带列裁剪、不 SELECT *；两道闸不放宽。
src/tools.js：memory_pin 工具。

验收

存量库升级后新表为空 → 回落旧类型口径，两臂在真库副本上逐条 id 相同（maxItems 5 与 10 都验过）
预算 0 时任何路径都不改注入序列
归档 / 遗忘 / 硬删三种场景各有用例
向量路填满 poolSize 时 pin 仍拿满预算
暂停作用域下回执如实为 false
全量 2858 用例 / 2857 通过 / 0 失败 / 1 跳过（src↔lib 一致性守门通过）

不做

PINNED_MEMORY_TYPES 保持原样不动 —— 它在 write-admission 还承担写入配额豁免语义，与注入侧是两个不同的事，本线只把注入侧解耦。

Summary by CodeRabbit

新功能
- 新增记忆钉住与取消钉住功能，可添加备注并查看钉住状态。
- 钉住的有效记忆可优先参与注入，包括原候选范围之外的记忆；遗忘、归档或暂停作用域仍会阻止注入。
- 默认可用工具数量增至 12 个；启用整理功能后增至 13 个。
文档
- 更新了工具说明及相关架构信息。

pin 筛选发生在 hybrid 合并之后，而 merged 已按 poolSize 封顶（生产 maxItems=5 → poolSize=10，向量路一次正好返回 10 条即 break）。规则窗口里的 constraint/preference 因此一条都进不了 candidates， pin 池只能从那 10 条里碰运气选，与「pin 不占 maxItems 名额」（本文件 :1919 注释、issue #249 验收）不一致。修法：合并块之后、topic 重排之前，把被 poolSize 挤掉的 pin 类行补到候选池尾部。两条纪律： 1) 只在 pinnedInjectBudget > 0 时补，预算关时 candidates 与改前一致； 2) 只补到尾部，strictScope 与 scopeState 两道闸门照旧作用其上，「pin 池 eligible 取自过滤之后的候选」的位置纪律不变。空 query 时 hybrid 分支不执行（candidates === items），补丁不触发，不会出现空 query 下 pin 池变大。实测真库副本（6733 条有向量行、同一条 query、1024 维 queryVector，与生产 vector 配置 BAAI/bge-large-zh-v1.5 同维，pinnedInjectBudget=5， maxItems=5）： - 改前 pin shown 2/5，注入 7 条 - 改后 pin shown 5/5，suppressed=6，注入 10 条 - 无向量路径改前改后都 5/5、10 条且逐条同序 → 补丁不改本来正常的路径 - 前 5 位新进 011b7379（反对 AI 赋魅）／db02b018（第三方个人信息不该长期保存）／b3457756（拒绝谄媚，要客观视角）；原有条目只后移（dfd8ef81 3→6、39143dc6 4→7、03532333 5→8、66d470a4 6→9、 9813b46b 7→10），无任何一条被挤出注入块。测试 test/inject-pin-vector-crowd.test.js（5 条）：向量路填满 poolSize 时 pin 仍拿满预算、pin 取自规则窗口而非封顶 candidates、预算为 0 时零行为变化、补回的 pin 仍受 strictScope 硬过滤、仍受 scopeState 拦截档约束。全量 node --test test/*.test.js：tests 2820 / pass 2819 / fail 0 / skip 1。

旧口径把「类型是 constraint/preference」当成 pin 的隐含假设，于是这些类型的每一条都自动具备「每轮必进」的资格，而预算只有 5——池子本身过大，稳定偏好只能靠相关性去挤那 10 个名额，挤不进去也无声。本次把「哪几条是用户亲手钉的」变成一条显式事实，注入侧只认这张表。存储：新增 pinned_memories(memory_id PRIMARY KEY, created_at, note) 与 idx_pinned_created。独立表而非主表布尔列——回退只需一条 DROP，不碰主表的 31 列；pin 是「用户与记忆之间的一条关系」，created_at 还能给出 pin 顺序。外泄面为零：mirror/share 都不 SELECT 本表。幂等靠 CREATE TABLE IF NOT EXISTS，不登记 applied_migrations（本表没有回填步骤）。取数：pin 行可能不在 200 行候选窗口内，所以按 id 点查而不是靠窗口扫。点查带列裁剪（复用 PRAGMA 派生的列清单，已排除 embedding），不 SELECT *。两道闸不放宽：点查回来的行仍要过 strictScope 与 scopeState 两道过滤——补进 candidates 之后再走闸，而不是绕过它们。eligible 只从「已过闸的候选」里取，次序按 pin 先后。升级等价：存量库升级后新表为空。此时回落到旧的类型口径，pinnedStats.source 标记为 type-fallback；用户 pin 第一条后切换到 explicit。两臂在真库副本上逐条 id 相同（maxItems=5 与 10 都验过），预算 0 时任何路径都不改注入序列。 pinnedStats 新增两个观测点：source（explicit / type-fallback / undefined）与 outsideWindow（靠点查补进来的条数，即补丁存在的理由本身）。 PINNED_MEMORY_TYPES 保持原样不动：它在 write-admission 还承担写入配额豁免语义，与注入侧是两个不同的事，本次只把注入侧解耦。测试 test/inject-pin-explicit.test.js 七条：空表回落、窗口外仍能注入（造 220 条同 importance 行，否则窗口装得下会假绿）、pattern 类型可 pin、越权不进块、暂停作用域不进块、预算 0 零变化、遗忘/归档不进块。四个变异分别加回类型过滤、去掉遗忘归档过滤、空表不回落、eligible 忽略两道闸，均被对应用例咬住。

原注释说「老还没变」的稳定偏好排在最近才钉的后面，代码是 created_at ASC + eligible.slice(0, pinnedBudget)，实际是先钉的占住名额、最近才钉的先被挤掉。注释与代码方向相反，下一个人读注释会以为要改成 DESC。顺便把这条方向为什么成立写清楚：pin 是「长期带着」的承诺，越早做出、越久没撤回就越该占名额；反过来让新钉的优先，pin 就退化成「最近关注」清单。另标注排序键是「什么时候钉的」而非内容的 updated_at，两个轴别混。只改注释，不动代码。

## 判据（这一个是 bug，不是清理）上一版把「pin 口径」的判据写成 countPinned() > 0，即「pinned_memories 表里有几行」。这条判据是错的：pin 行会在 memories 那边被**归档、遗忘、硬删**，而 pinned_memories 对这三种一无所知。只要表里还剩一行（哪怕那一行早已归档），判据就一直判 explicit，于是 eligible 恒为空 —— pin 全灭，且**永不回落到旧的类型口径**，无日志无报错。复现四场景：正常 pin 不触发；pin 后 setArchived 触发；pin 后 setForget 触发； pin 后 remove 触发。后三种里前两种最要紧，因为归档/遗忘是日常操作，比硬删常见得多 —— 所以补 DELETE 只能堵住硬删那一路，根因在判据。改法：判据从「表里有几行」改成「有几条能用的」。先按 id 点查回来，滤掉 forgotten/archived，再看这批是不是空的： - 有可用行 → explicit（只注入可用的那几条） - 表里钉过、但一条都用不了 → fallback-none-usable（回落旧类型口径，并留痕） - 表里从没钉过 → type-fallback（升级即等价）为什么「还有一条能用就留在 explicit」而不是整段回落：若因为「有 3 条归档」就回落类型口径，会突然冒出一批她根本没钉过的条目，那比少注入更糟。 pinnedStats.source 因此多一档 fallback-none-usable —— 静默降级必须留痕，否则读的人只看到「pin 一条都没注入」却不知道为什么。 ## 清理（配套，不是修法） remove() 与 deleteBySharePackId() 原本都会显式清 memory_provenance / memory_mints，但没清 pinned_memories，建表时也没抄 REFERENCES ... ON DELETE CASCADE。两条路径各补一条 DELETE，位置紧接前两条之后、删 memories 之前。这一条只防攒垃圾；判据改不动的话补 DELETE 也救不了归档/遗忘两路。 ## memory_pin 工具到此为止 pin 只有存储、没有写入入口：tools.js / api.js / api-standalone.js / cli / client.js 五处全无。按 set_scope_state 那套走工具层（政策类工具不进 api 层是既有惯例），service 返回表照 setScopeState 的写法加四个转发（纯 bookkeeping，不挂 write hook —— pin 一条不该让 mirror 重渲染）。工具边界： - 参数 id 必填、note 可选、unpin 可选 - 存在性校验走 visibleForTool，strictScope 下他 scope 的行按「不存在」处理，与 memory_delete 同款无存在性泄漏 - 回执如实回显库现值（重钉不刷新 created_at，回显它才看得出「这次没改变顺序」） - injectable 字段报告「钉着 ≠ 会注入」：遗忘/归档/暂停作用域都优先于 pin - unpin 幂等：本来没钉也返回 pinned:false，不报错 ## 测试 test/inject-pin-explicit.test.js 由 7 条增到 11 条，新增四条锁判据：归档后回落、遗忘后回落、硬删后回落且孤儿行被清、多条里只有一部分能用时留 explicit 且不冒出旧口径条目。四个变异全部被咬住： - 判据退回 countPinned() > 0 → 归档/遗忘两条变红 - 删掉 remove() 里的 pin DELETE → 硬删那条变红 - 去掉 forgotten/archived 过滤 → 四条变红 - fallback-none-usable 并回 type-fallback → 归档/遗忘两条变红工具侧同步：tools.test.js 名字表与计数（12/13）、tools-dto-schema-matrix.test.js 的 TOOL_NAMES + drive 块（含 unpin 幂等分支）、session-gate.test.js 的注册数、 README 模型工具表与两处计数。全量：tests 2831 / pass 2830 / fail 0 / skip 1。npm run sync 后 src 与 lib 逐文件哈希一致。

## 缺陷 memory_pin 的描述文案、README 与 render 文案三处都写着「遗忘 / 归档 / **暂停作用域**都优先于 pin，回执里 injectable 如实报告」，但 execute 里只算了两项： const injectable = !target.forgotten && !target.archived; 于是同一条被按下作用域的行（enforce 档）会报 injectable: true 而实际一条都没注入。三组对照：按下暂停 → 回执 true、注入 0 条；不按暂停 → 回执 true、注入 1 条、这条在里面；暂停中钉、解除后重钉 → 两次都报 true。报 true 的两种处境里一种真会注入、一种被挡住，回执分不出来。这正是「返回成功不等于生效」。注入侧本身没坏——scopeStateGate 一直在拦。坏的是回执那段代码自己另写了一份判据，与闸门不同源。 ## 改法 const injectable = !target.forgotten && !target.archived && service.filterPaused([target]).length > 0; 用 filterPaused（src/service.js:2800，即 scopeStateGate.filter）而不是自己拼 matchPausedScopes：回执与注入侧共用同一个出口，以后改闸不会漏掉回执这一侧。分档语义由这个出口自己给出，不需要在工具层再判开关： - enforce 开 → 真剔掉，回执 false - 只开 enabled（观察档）→ 一条都不拦，回执 true（此时报 false 才是假警报） - 两个都关 → 同样不拦，回执 true ## 测试补在 test/tools.test.js（tools 侧），因为注入侧早已锁了「暂停域的行不进块」，而回执是另一段代码、可以照样撒谎——缺口就在这里。三条： - enforce 档：回执 injectable: false，且同一条真的不出现注入块里（回执与行为同向，不只断言回执） - 观察档：回执 injectable: true，且这条真的进块（方向相反的假警报也要防） - 遗忘 / 归档：两项仍报 false（原有语义不能被这次改动弄丢）两个变异都被咬住：退回只算遗忘/归档 → 第一条红；把 scope-state.js 的 !enforce() 去掉（观察档也拦）→ 第二条红。 ## 顺手修的一个测试坑 pinnedInjectBudget 是从 config 读的（src/service.js:1885），不是 injectCandidates 的入参。传进调用参数会被静默忽略——测试会绿、pin 池根本没开。测试里已改成喂 config，并在注释里写明。全量：tests 2834 / pass 2833 / fail 0 / skip 1。npm run sync 后 src 与 lib 的 tools.js 哈希一致。

先处理缺失的记忆记录。

当 strictScope 开启且会话作用域已解析时，不存在的 ID 会让 visibleForTool 把 undefined 传给 service.isVisibleInScope。该函数随后访问 m.agent_scope_source，因此工具抛出 TypeError，不会返回 memory not found。

请在可见性检查前放行缺失记录，让 memory_pin 的现有检查返回正常错误。

slow-stack#593 把 pin 从「按类型推断」改成显式存储（pinned_memories 表）后，两处消费方没跟上，各自退回旧口径： ① src/document.js 的 evidence 吸收只按 pinnedTypes.has(row.type) 判「谁属于保真池」，拿不到 pin 表就只能按类型猜 —— 一条被显式钉住的 pattern / decision 在文档升格时照样被 setArchived 静默归档。新增 store.isPinned(memoryId) 单行点查（pinned_memories 的唯一读侧谓词），吸收判据改为「显式钉住或类型保真池」两条并列；谓词缺席时退回类型口径（fail-safe）。 ② src/tools.js 的 injectable 只看遗忘 / 归档 / 暂停作用域，没看 pin 池的总开关。pin 池由 pinnedInjectBudget 决定（src/service.js:1885 的 pinnedBudget > 0 才读表选路），而它默认 0 = 关闭 —— 预算 0 时钉住的动作确实成功，但一条都不会被注入，回执照样报 true，正是「返回成功不等于生效」。补上 pinnedBudget > 0，上限与 service.js 同款 Math.min(5, ...)，工具描述与 blocked 文案同步。候选池侧的 type / importance / codingGate 闸仍不建模：那几道闸随候选池变化，回执只回答「pin 这条通道此刻开不开」。回归锁： - test/document.test.js 用 type:"pattern"（刻意不在 PINNED_MEMORY_TYPES 里，否则会被类型口径顺手护住、测不到缺口）钉一条不钉一条，断言被钉行未归档。 - test/tools.test.js 锁预算 0 时 pinned:true 与 injectable:false 分开报。 - test/tools-dto-schema-matrix.test.js 的 injectable 断言由 true 改 false （该矩阵用默认配置，预算本就是 0）。验证：npm test 2874 tests / 2873 pass / 0 fail / 1 skipped；npm run sync 95 文件一致。
