feat(dream): dream 审计行输入快照瘦身，opt-in 默认关（#557 建议 2） by modusensus · Pull Request #625 · slow-stack/mneme

modusensus · 2026-11-09T19:40:39Z

背景

#557：dream_runs 是唯一没有任何保留期/回收口的日志表（四个 *RetentionDays 都不覆盖它），且 input 单行体积随记忆量涨（#557 实测平均 40-79 KB/轮，绝大部分是 content）、轮数随天数涨，两者相乘超线性（报告库占 43% 的页；跑过 #275 reclaim 的库会削掉大半，但 reclaim 是手动入口）。

issue 评论区已对齐解法空间：删行被拍板 3 锁死（src/maintenance.js:14：裁列同意、删行不同意），本 PR 按建议 2（input 只存摘要）落写入期瘦身，并按评论区口径按 run_type 分叉。

改动

新键 dreamInputSummaryEnabled（opt-in 默认 false = 审计行逐字节一致），开启后 auto 轮快照只落骨架：id/type/title/importance/updated_at，不含 content。

判定与回执不受影响：巩固的 LLM 输入由记忆库现算（dream.js 的 listText 不经过落库副本）、snapshot_hash 在内存里对含 content 的快照计算——prompt 与 receipt 完整性不变。变的是离线回放：原文不在库里就重算不出 hash，[feature] 蒸馏归因只到「会话区间」，到不了「哪一次蒸馏」——补 run 概念（schema + 写入 + 回填） #512「每一行都能回放一次巩固」对瘦身轮降级为骨架级（docs/STORAGE.md 已写明；[Feature] 存储生命周期：归档区出口 + 审计表保留（容量治理议题） #275 reclaim 清过 input 的库本就丢过这层，本键把同一权衡前移到写入期）。
organize 轮结构性豁免：整理轮的重放载荷走 organize.js 自己的 saveDreamRun，不经过 dream.js 的快照构造点——与 reclaim 清 input 的 run_type != 'organize' 谓词同一条边界，apply 重放永远不会被瘦身破坏。
sleep 轮本就 input: null，不受影响。

明确不做的（与 issue 口径一致）

不删行（建议 1）：拍板 3 不动。顺带回替代论区的悬空问题：receipt_chain.run_id / memory_mints.run_id 都是裸 TEXT NOT NULL 无外键（src/store.js:154 / :401），删行会产生悬空指针——但本 PR 不删行，该问题不存在；
decisions / outcome / raw_output 的裁列扩展（评论区替代方向 1）：需要先改 docs/STORAGE.md 的零损失承诺行，属拍板事项，不搭车；
建议 3（四个保留期键进设置面板）：四处联动（settings 白名单 + api.js NESTED 表 + client.js 面板行 + i18n），单独立件，不在本 PR。

测试与门禁

test/dream.test.js 新增 2 例：默认关 content 原样落库（键集 deepEqual）/ 开启后骨架 + input_count/snapshot_hash/receipt/decisions 形状不变 + 骨架尺寸哨兵（<2KB）；
test/api.test.js 计数锁 121 → 122，默认值钉 false；
全量 node --test test/*.test.js：3156 用例 / 3155 通过 / 0 失败 / 1 跳过；check-sync 118 一致；
docs/CONFIGURATION.md 补键说明（schema 每键有说明的锁）、docs/STORAGE.md 补写入期瘦身与拍板边界、CHANGELOG 记录；
euthyna 阶段 B 审计已过：audit/history --pickaxe/coverage（c8 全量：runDream 130 次、saveDreamRun 388 次调用计数在案）→ 2 条删除行线索逐条阶段 C 证否（全量 map 以三元默认分支等价重加、计数锁按检查单 +1 维护），0 TRUE POSITIVE / 2 FALSE POSITIVE；euthyna gate --verify 退出码 0。报告在车道 .worktrees/557-dream-input/MNEME_DREAMINPUT_EUTHYNA_AUDIT_2026-11-10.md（不进库）。

不写 Closes：#557 的建议 3（面板白名单）与 decisions/outcome 裁列讨论还在 issue 上挂着。

Summary by CodeRabbit

新功能
- 新增可选的输入摘要设置，默认关闭。开启后，自动巩固轮的审计记录不再保存记忆正文，仅保留标题等摘要信息；不影响巩固判断或输入哈希计算。
- 组织轮的重放数据不受此设置影响。
文档
- 补充设置说明及其对审计记录和离线回放能力的影响。

#557：dream_runs.input 单行体积随记忆量涨（实测 40-79 KB/轮，大头是 content），轮数又随天数涨，超线性增长（报告库占 43% 的页），且它是唯一没有保留期/回收口的日志表（四个 *RetentionDays 都不覆盖它）。删行被拍板 3 锁死（裁列同意、删行不同意），本变更按 issue 建议 2 落写入期瘦身：新键 dreamInputSummaryEnabled（默认 false = 审计行逐字节一致），开启后 auto 轮快照只落骨架（id/type/title/importance/updated_at，不含 content）。 LLM 输入由记忆库现算、snapshot_hash 在内存里对含 content 快照计算—— prompt 与 receipt 完整性不变；变的只是离线回放（骨架级）。 organize 轮结构性豁免：重放载荷走 organize.js 自己的 saveDreamRun，与 reclaim 的 run_type != 'organize' 谓词同一条边界。sleep 轮本就 input=null。 test: dream.test.js 新增 2 例；api.test.js 计数锁 121→122 + 默认值钉； CONFIGURATION.md / STORAGE.md / CHANGELOG 同步。全量 3156 用例 / 3155 通过 / 0 失败 / 1 跳过；check-sync 118 一致。

Walkthrough

新增默认关闭的 dreamInputSummaryEnabled 配置。启用后，auto 巩固轮写入的审计快照省略记忆正文；LLM 输入和 snapshot_hash 仍使用含正文的内存快照。organize 轮的重放载荷不受影响。

Changes: Auto 巩固审计快照精简

Layer / File(s)	Summary
配置与功能标志 `dsh-mneme/lib/config.js`, `dsh-mneme/src/config.js`, `dsh-mneme/lib/settings.js`, `dsh-mneme/src/settings.js`, `dsh-mneme/test/api.test.js`	新增默认关闭的布尔配置和可持久化功能标志。API 测试覆盖默认值，并更新配置键数量断言。
审计快照写入与验证 `dsh-mneme/lib/dream.js`, `dsh-mneme/src/dream.js`, `dsh-mneme/test/dream.test.js`, `dsh-mneme/docs/CONFIGURATION.md`, `dsh-mneme/docs/STORAGE.md`, `dsh-mneme/CHANGELOG.md`	启用配置后，auto 巩固轮写入的审计快照保留 `id`、`type`、`title`、`importance` 和 `updated_at`，省略 `content`。测试验证默认和启用两种行为。文档说明完整内存快照仍用于 LLM 输入和哈希计算，瘦身后的审计行不能离线重算原文哈希。

断言启用瘦身时的完整快照哈希

当前断言只检查哈希长度。如果改为对不含 content 的快照计算哈希，测试仍会通过。请在运行前计算完整快照的预期哈希，并与审计行比较。

建议修改

-import { validateDecisions, applyDecisions, createDreamScheduler } from "../src/dream.js";
+import { validateDecisions, applyDecisions, createDreamScheduler, hashSnapshot } from "../src/dream.js";

   const ctx = mockCtx({ onConsolidation: sessionDecisions });
   const dream = createDreamScheduler({ thresholdCount: 1, thresholdChars: 0, delayMs: 0 });
+  const expectedHash = hashSnapshot(service.all());
   const result = await dream.runDream(ctx, service, {
     dreamProvider: "deepseek", dreamModel: "deepseek-chat",
     dreamInputSummaryEnabled: true

-  assert.ok(run.snapshot_hash && run.snapshot_hash.length === 64, "snapshot_hash 形状不变（内存里对含 content 快照计算）");
+  assert.equal(run.snapshot_hash, expectedHash, "snapshot_hash 基于含 content 的完整快照");

补齐电脑端面板开关，或说明电脑端不支持此设置。

dreamInputSummaryEnabled 默认关闭，但电脑端面板没有渲染该键。只使用电脑端面板的用户无法开启快照瘦身。

请增加开关、双语文案和面板测试。手机面板已有“其它”组动态入口；如果不打算支持电脑端，请在注释中明确这一限制。
