entity:和attr:查询经过共同后处理管线。
searchMemories()在两个前缀分支中直接返回。searchByEntity()和searchByAttr()只读取topK，并在各自的召回结果上直接截断；它们不会读取occurredFrom、occurredTo或scope，也不会调用inOccurredBounds()和scopeMultiplier()。因此，memory_search传入这些选项时，前缀查询仍会返回时间窗外的记录，且不会按会话 scope 重排。请让两个 helper 的候选结果进入同一后处理管线，并在时间过滤、scope 加权后再执行最终

仅在两个 scope 维度都匹配时加成。
A2 要求：agent_scope 和 workspace_scope 都可比较且都匹配时返回 SCOPE_MATCH_BOOST；存在可比较的不匹配维度时返回 SCOPE_FOREIGN_PENALTY；完全未标注或仅部分可比较的记录返回 1。
当前 scopeMultiplier() 在没有 foreign 维度时直接返回 1.25。因此，完全未标注记录和仅匹配一个维度的记录都会被错误加成。请在 dsh-mneme/src/service.js 和对应的 dsh-mneme/lib/service.js 中按上述三种情况计算乘数，并增加能区分 1 与 1.25 的回归测试；现有全局记录排序测试不足以检测该差异。

在融合截断之前应用时间窗过滤。
fuseRecall() 已在返回 fusedMerged 前按 lim 截断候选。此处再过滤无法补回被截断的窗内记录。
例如 topK=1 时，第一条关键词命中在窗外、第二条在窗内。mode="keyword" 会先只保留第一条，再在此处过滤为零条。结果错误地为空。
请让融合阶段接收未截断的候选池，或在各召回源截断前应用时间窗过滤。

在 scope 加权前保留超出 topK 的候选池。
store.search()、bm25Recall() 和 fuseRecall() 都可能在 scope 加权前截断候选。rerankCandidates() 也按 topK 返回结果。
当 foreign 候选占据原始 topK，而匹配候选紧随其后时，匹配候选不会进入加权阶段。因此，即使 scope 乘数会使其排名超过 foreign 候选，结果仍会错误地保留 foreign 候选。
请让召回、融合和 rerank 阶段保留足够大的候选池，并在 scope 加权后执行最终的 slice(0, lim)。这与 scopeMultiplier() 的具体逻辑和 occurred 过滤无关。

拒绝日历无效的日期边界。
updatedAtBounds() 仅检查 Date.parse() 是否为 NaN。因此，"2026-02-30" 会被接受为有效边界；occurredFrom 会归一化为 2026-03-02T00:00:00.000Z，occurredTo 也会进入 WHERE。这会产生错误的 occurred_at 过滤结果。
请在 dsh-mneme/src/store.js 和 dsh-mneme/lib/store.js 的 updatedAtBounds() 中验证日期组件，拒绝不存在的日历日期。请在 dsh-mneme/test/scope-retrieval.test.js 增加 "2026-02-30" 回归测试，并断言该边界不参与过滤。

v0.8.0 批次 A · A2 检索加权 + 时间过滤（Refs #17，2/4）
接 #153（A1 存储层）之后的检索侧软隔离。
scopeEnabled关闭或调用方未提供会话 scope 时，检索行为与 A2 前逐字节一致；strictScope 硬过滤在 A3、面板在 A4。English TL;DR: soft scope isolation at retrieval time — search results from the current session's scope get a ×1.25 boost, foreign-scope rows ×0.5 but stay visible (hard filtering is A3); unscoped (NULL) rows and unresolvable dimensions stay neutral. Plus an
occurred_attime-window filter (falling back tocreated_at) acrossmemory_search/memory_listand the search fusion pool, and the four A1 columns now surface through all three retrieval tools' outputs.变更点
options.scope（工具层从exec.agent.session解析后传入，复用 A1 的解析器）。两维命中 ×SCOPE_MATCH_BOOST(1.25)；任一维度 foreign ×SCOPE_FOREIGN_PENALTY(0.5)，保留可见。与trustEpistemicWeighting同款收尾（乘分→降序→截 topK）。系数是模块常量非配置项——A2 只定性行为，数值等线上检索质量反馈再调。store.list/count新增occurredFrom/occurredTo（与 updated_at 共用updatedAtBounds归一化，date-only 含当日，非法值忽略不进 WHERE）；按COALESCE(occurred_at, created_at)比较——未标注行（含全部存量）回退创建时间，过滤器对旧库可用。搜索路径在融合池上先滤再 dedup/slice，rerank 只看窗内候选；list 与 count 同口径，分页 total 与行一致。memory_search/memory_list新增可选occurred_from/occurred_to；memory_search接exec做 scope 加权；三个检索工具输出 schema 与 render 透出四字段（provenance 附加段只在有标注时出现，未标注行渲染与 A2 前一致）。execution results validate against their declared output schemas抓的就是这个，条件展开后既有测试全过、无测试改动）。updatedAtBounds从 store.js 导出复用（SQL 过滤与搜索后置过滤同一套边界归一）。测试
test/scope-retrieval.test.js13 项：list/count 窗口与 COALESCE 回退（用刚写入行的 created_at 推导「今天」，不依赖测试机时钟/时区）、搜索窗、加权翻转/未标注中性/flag 关不动分、toApiList 形状、三工具接线。边界说明（给 reviewer）
