fix(pin): 显式钉住的行不被文档升格收走；pin 回执算上 pinnedInjectBudget by modusensus · Pull Request #596 · slow-stack/mneme

modusensus · 2026-11-06T17:52:08Z

#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。这个 PR 补齐两处旁路。

① 显式钉住的行仍会被文档升格吸收静默归档

src/document.js 的 evidence 吸收只按 pinnedTypes.has(row.type) 判「谁属于保真池」——它拿不到 pin 表，就只能按类型猜。于是被显式钉住的 pattern / decision 在文档升格时照样 setArchived，钉过的行被悄悄收走，pin 语义当场失效。

修法：新增 store.isPinned(memoryId) 单行点查（pinned_memories 的唯一读侧谓词），吸收判据改为两条并列——explicitlyPinned || pinnedTypes.has(row.type) || ABSORB_EXEMPT_TYPES.has(row.type)。store.isPinned 缺席时自动退回类型口径（fail-safe，不因新谓词缺失而放宽）。

② `memory_pin` 回执在 `pinnedInjectBudget=0` 时仍报 `injectable: true`

pin 池整体由这个预算开关：src/service.js:1885 里 pinnedBudget > 0 才读表选路，而它 default(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」。

修法：injectable 补上 pinnedBudget > 0，上限与 service.js 同款 Math.max(0, Math.min(5, Math.floor(config?.pinnedInjectBudget ?? 0)))；工具 description、schema 注释与 blocked 文案同步。

刻意没做的：候选池侧的 type / importance / codingGate 闸不建模——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」。已写进注释与 CHANGELOG，免得下次被当成漏修。

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，注册文档吸收两条，断言被钉行 archived===false、未钉行 archived===true、evidence_archived===1。
test/tools.test.js：预算 0 时 pinned:true 与 injectable:false 分开报。
test/tools-dto-schema-matrix.test.js：injectable 断言由 true 改 false（该矩阵用默认配置，预算本就是 0）。

变异自证

变异	结果
`explicitlyPinned = false`（退回只看类型）	`pass 28 / fail 1` ✅ 转红
撤掉 `pinnedBudget > 0`	`pass 39 / fail 2` ✅ 转红（新用例 + 矩阵）
全部还原	`pass 70 / fail 0`

验证

npm test                   → tests 2874 / pass 2873 / fail 0 / skipped 1
npm run sync               → Synced 95 file(s) from src/ to lib/
node scripts/check-sync.js → ✓ src/ 与 lib/ 一致（95 个文件）

合并 ≠ 生效：本机装的是 0.11.0 发布版，这条链路要等下次发版装机才走到新代码上。

Summary by CodeRabbit

功能调整
- 文档吸收时，显式置顶的记忆不会自动归档；未置顶且不属于受保护类型的记忆仍会归档。
- 置顶回执会根据注入预算和自动注入设置报告置顶通道是否可用。预算默认为 0，且限制在 0 至 5 之间；预算为 0 或明确关闭自动注入时，即使置顶成功也会报告不可注入。记忆仍可能通过常规候选路径进入上下文。
测试
- 增加回归验证，覆盖置顶记忆的归档保护及不同预算和自动注入设置下的回执。

#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。

Walkthrough

新增显式 pin 查询，并在文档证据吸收时保护已 pin 的行。memory_pin 回执在 pin 注入预算大于零、autoInject 未显式关闭且原有条件通过时，报告 injectable: true。

Changes: 显式 pin 与注入行为

Layer / File(s)	Summary
显式 pin 查询与证据归档保护 `dsh-mneme/lib/store.js`, `dsh-mneme/src/store.js`, `dsh-mneme/lib/document.js`, `dsh-mneme/src/document.js`, `dsh-mneme/test/document.test.js`	store 新增 `isPinned(memoryId)` 查询。文档吸收在显式 pin 或类型保护条件成立时跳过归档；若 `store.isPinned` 不可用，则继续使用类型判定。新增测试验证已 pin 的 `pattern` 行保持未归档。
memory_pin 注入预算与回执 `dsh-mneme/lib/tools.js`, `dsh-mneme/src/tools.js`, `dsh-mneme/test/tools-dto-schema-matrix.test.js`, `dsh-mneme/test/tools.test.js`, `dsh-mneme/CHANGELOG.md`	`injectable` 还要求 pin 注入预算大于零，且 `autoInject` 未显式设为 `false`。说明和回执文案指出，`injectable: false` 不排除记忆经常规候选路径进入上下文。相关测试和变更记录同步更新。

#596 的 CodeRabbit 评审指出两处 Minor，均属「返回成功不等于生效」： 1. pinnedInjectBudget=0 时只关掉 pin 通道，这条记忆仍可能凭自身重要性走常规候选路进块，而工具描述 / blocked 文案 / CHANGELOG 写成「不会被注入」，是过度承诺。文案改为「pin 通道此刻关闭」，并明确回执回答的是通道开不开，不是这条记忆被排除在所有块之外。 2. autoInject 是整条注入通道的总闸（src/index.js:617 只在它开着时注册注入器），关着时 pin 段一行都跑不到，而回执仍报 injectable: true。 execute 判据补 autoInjectOn = config?.autoInject !== false，按「只有显式 false 才算关」判，避免测试直连 createTools 拿不到已填 defaults 的 config 时误报 false。回归：test/tools.test.js 新增一例，同时锁 autoInject:false 报 false 与不显式传时不得误报 false。变异自证：撤掉 autoInjectOn → 34 pass / 1 fail。 npm test 2875 tests / 2874 pass / 0 fail / 1 skipped；check-sync 95 一致。

状态复核（本轮）：两条 CodeRabbit Minor 意见都已在 685ba49 处理，评审侧已标 ✅ Addressed。

src/tools.js:554-559：injectable 增加 autoInjectOn（config?.autoInject !== false）判据 —— autoInject 关着时宿主根本不注册注入器，pin 段一行都跑不到，回执照样报 true 属于「返回成功不等于生效」。
src/tools.js:501/:519-533：工具描述、schema 注释、blocked 文案统一改成「pin 通道此刻关闭」，并写明回执照回答的是通道开不开，不是这条记忆被排除在所有块之外（上一版文案是过度承诺）。

验证：npm test → 2875 tests / 2874 pass / 0 fail / 1 skipped；npm run sync + check-sync → 95 文件一致；CI 13 项 12 pass + 1 skipping（osv-scanner 恒跳过）。mergeStateStatus 已是 CLEAN。

等待维护者合并（按仓库纪律不自行合并）。
