With the full candidate pool, injection can drop eligible local memories when hard filters such as strict scope remove higher-ranked rows after the cut. A transaction rollback can also leave a stale candidate cache until the next write. Apply the hard filters before truncating the ranked pool and avoid caching inside transactions before merging.

现有输入不要求 updated_at 或 id 决定名次,因此删除两个平局键后测试仍通过。可以在首次注入前通过测试库固定时间戳,分别构造“同分、不同 updated_at”和“同分、同 updated_at、ID 与插入顺序相反”的候选,再断言入选顺序。Based on learnings, 验证平局规则的输入必须让该规则实际决定结果。

在 `inject-pool-full.test.js` 的注入测试中补充能区分平局规则的候选数据:首次注入前固定测试库时间戳,分别验证同分但 `updated_at` 不同,以及同分且 `updated_at` 相同、但 ID 顺序与插入顺序相反的情况;断言实际入选顺序确实由这两个排序键决定。

在 README 说明注入候选范围的变化。
本次改动让窗口外的活跃记忆也能参与自动注入,但这里仅更新了测试数量。请在注入功能说明处增加一句,说明规则排序覆盖全部活跃候选,正文仅为入选候选读取。As per coding guidelines, “user-visible changes include their README line in the same PR.”

不要复用事务中读取的候选池。
如果 service.transaction 在保存 A 后调用 injectCandidates,Line 667 会将未提交的 A 缓存为 generation 1。事务回滚后,下一次保存 B 会再次产生 generation 1。Line 660 随即命中含 A 的缓存;回表找不到 A,也不会选择 B。结果会保持错误,直到再次写入。事务内不要写入此缓存,并避免从事务内复用缓存快照。

问题
注入的规则池此前是
store.list({ limit: 200 })(src/service.js),窗口按importance DESC取。也就是说:谁能参与排序,由一个固定的前 200 名决定,真正生效的排序规则(summary 优先档 → preference → importance×quality×heat×scope)只在这 200 条内部起作用。本机库实测(9067 条活跃记忆):
最后一行是这次修复最直接的证据:窗口内全是 importance 5,
summary优先档这条规则在最需要它的场景里从来没机会触发。做法
改成三段式:
store.listInjectPool()取全部活跃行的排序键(12 列:id / type / source / importance / quality_score / last_accessed_at / created_at / updated_at / agent_scope / workspace_scope / archived / forgotten);max(200, poolSize)条回表补正文(listByIdsForInject)。回表深度与改动前一致(200),所以 backfill(槽位没填满时往下补)的行为不变。
为什么不用
store.list({ limit: null }):list 的投影由 PRAGMA 派生、搬全部列(含 content),9k 行实测 340–400ms;12 列排序键 200ms,正文只对 200 条点查回来 6.8ms。这不是变快——改动前那条LIMIT 200查询约 76ms。这是用「多扫一遍排序键」换「看不见的记忆能进候选」。缓存:排序键按
mirror_state.generation缓存,与词法索引同纪律(水位每次现读、读不到时不写缓存、只缓存不写查询结果)。但heatEnabled && injectHeatEnabled同时打开时绕开缓存——heat 依赖last_accessed_at,而touchLastAccess刻意不 bump generation(读不该让镜像变脏),缓存会让 heat 停在上一轮读数上。末位平局键:排序改为先算键再排(
.map(...).sort(...),8k 行不必在 comparator 里反复算 priority),并补updated_at DESC再id。此前同分组的次序靠Array.sort的稳定性继承 SQL 行序——全库只有 43 种排序键取值、37 个并列组、最大一组 2276 行,改一行updated_at就能造成上千对交换。现在同分组次序可复现,轮换窗口不会因为一次无关写入整批换人。测试
新增
test/inject-pool-full.test.js4 条:content/tags,证明走了回表而不是直接返回排序键快照。全量
node --test test/*.test.js:3446 tests / 3445 pass / 0 fail / 1 skipped(skip 是 Windows 未开开发者模式的符号链接用例)。npm run sync124 文件一致。变异自证(四轮,各自变红)
一处变异假绿,已写进 CHANGELOG:删掉
updated_at/id两个平局键后 4 条用例全绿。原因是updated_at由save()铸造、精度到毫秒,测试造不出「同分且同updated_at」的两行;靠毫秒碰撞造数据的用例本身会随机红绿。所以平局键的收益今天只能靠代码审查守住,不假装它被测试覆盖了。未做
computeHeat/scopeMultiplier:它们是浮点连续函数,搬不进 SQLORDER BY,所以排序必须留在 JS 侧。Summary by CodeRabbit
