Merge Risk: ⚪ Minimal · up to The remaining test-cleanup concern does not block merging. Daemon shutdown, missing port arguments, and cleartext HTTP limitations are addressed. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The daemon retains the existing API authentication and normally binds to loopback, but running it alongside the host creates shared-state risks: a concurrent mirror update may leave deleted content on disk, and simultaneous first starts may disagree about the shared token. Actual network exposure depends on deployment settings that were not available for review. Retained concerns

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
--port 后面缺少值时，没有报错。
用户执行 --port 后直接结束参数，或者紧跟 -h，args.port 都会被设为 true。Number(true) 的结果是 1，能通过校验，所以端口 1 会被当作合法端口。用户本来是参数写错，启动却改成了绑定端口 1。在非 root 环境下，这会报 EACCES，但错误提示和真正原因无关。建议在 --port、--host、--memory-dir 缺少值时直接调用 fail。
🐛 修复建议
const v = argv[i + 1];
- if (v !== undefined && !v.startsWith("--")) { out[a.slice(2)] = v; i++; }
- else out[a.slice(2)] = true;
+ if (v !== undefined && !v.startsWith("-")) { out[a.slice(2)] = v; i++; }
+ else fail(`${a} 缺少参数值`);Based on learnings：要区分“缺少标志”和“标志存在但缺少值”这两种情况。

dispose() 不等待 server.close 完成，就同步关闭数据库。 server.close() 不等待在途连接结束。在途的 PUT/POST 请求会在数据库关闭后才访问 store，结果是返回 500，或者写入丢失。
dsh-mneme/src/serve.js#L97-L100：让dispose返回 Promise。先调用closeIdleConnections()，再在server.close回调里调用store.close()。dsh-mneme/lib/serve.js#L97-L100：同步做同样的修改。在bin/dsh-mneme-serve.mjs中，shutdown先 awaitdispose()，再执行process.exit(0)。

背景
#363（Mneme Bridge，DeepSeek 网页端接入）确立的方向：第三方集成需要长期挂载记忆库，而 DSH 不必一直开着。本 PR 交付讨论回帖承诺的官方推荐挂载姿势——独立服务 daemon（
dsh-mneme-serve），在 DSH 宿主之外把数据面跑成常驻进程；lib 直挂的 embedded 模式从此降级为无网兜底。设计决策
cli.mjs子命令：CONTRIBUTING「The CLI is dependency-free by contract」禁止给bin/cli.mjs加 import，而 serve 必须挂载 lib；命名循dsh-mneme-mcp先例。createStandaloneApi（零 ctx 依赖、参数注入）：路由与鉴权零新面；唯一新增strictPort选项——daemon 的配置端口被占即报错退出而非顺延（第三方把 URL 写死，静默换端口等于坏）。不传该选项的宿主旁路行为逐字节不变。src/index.jsapply 的其余环节与宿主 ctx 纠缠，防御段纪律「最后动或不动」；src/serve.js约 60 行装配每步注释锚定 index.js 来源行号，漂移风险由多进程共存测试兜底。external_api，首次启动自动生成并持久化），端口/主机解析链与外部访问完全一致（显式参数 > 持久值 > 默认 8790/127.0.0.1）。变更清单
src/serve.jscreateServeRuntime({memoryDir, port, host, logger, strictPort})：装配链 store → settings → mirror → service(最小 config) → recoverMirror → 人改镜像合并 → recall recorder → maintenance → standalone API，返回{api, store, service, settings, maintenance, tokenExisted, dispose}；第三方可直接 import 自行托管生命周期bin/dsh-mneme-serve.mjs--memory-dir/--port/--host；stdout 仅就绪时一行机器可读 listening 行，日志走 stderr；SIGINT/SIGTERM 优雅收库（Windows 强杀由 WAL 回放兜底）src/api-standalone.jslistenWithRetry/createStandaloneApi增可选strictPort（EADDRINUSE 即 reject）package.jsonfiles白名单已含bin/，release.yml 无需动）docs/DAEMON.md（职责边界/对外接口/内部文件/已知坑六条）、包内 README 新小节、根 README 双语提及 + 文档表加行、AGENTS.md（模块地图「对外四张脸」+ 并行工作区段补 daemon 纪律）、CHANGELOG[Unreleased]、CONTRIBUTING（serve 豁免 cli.mjs 零依赖契约的条款）兼容性与影响面
纯增量：不改任何默认行为、不动 schema、不动现有路由语义、不加宿主配置键。唯一的存量交互变化是文档明示的运维约定：daemon 与 DSH「外部访问」抢同一默认端口，二选一（daemon 侧 strictPort 报错退出；反方向宿主侧保持既有的静默顺延）。
门禁
npm run sync后 check-sync 过；测试徽章已刷 1497 → 1502。test/serve.test.js×3：health 免鉴权/无 token 401、save → search 全链路、token 持久化与二次启动复用、recall_runs 回执落库（Mneme Bridge — 将 DeepSeek 网页端接入 mneme 记忆库 #363 回帖「第三方检索的复用统计不缺数」的回归锁）；test/serve-bin.test.js×1：真子进程 spawn + 多进程共存锁——daemon 与测试进程同库互写互读（本 feature 唯一的真新风险点；异步 spawn，遵守 maintenance.test.js 教训）；test/standalone-api.test.js×1：strictPort busy → reject，默认路径仍顺延。不在本 PR（按承诺另行推进）
index.js:338-444纯搬移抽出 embedder/reranker 装配为src/semantic.js，daemon 接线 +--embed（runtime 走 download 档，不用宿主 adopt 推导）。GET /context、POST /summarize：按 Mneme Bridge — 将 DeepSeek 网页端接入 mneme 记忆库 #363 回帖承诺走 issue 设计（蒸馏端点倾向「只返回候选，调用方走 saveWithDedupe」）。docs/DAEMON.md「已知坑」写明。Summary by CodeRabbit
