+### L-WIRE 2026-09-30
+
+1. **serve 真实接线范围**  
+   - 原条款：TASKS 总控接线；listener/broker/admin/注册/消息周期循环挂到进程。  
+   - 实际做法：`cmd/nixmsg/serve.go` 注入真实 `auth.NewPool`/`NewSessionTokens`/`NewAPITokens`/`NewLoginLocks`，挂注册与管理路由（踢线调 `Session.Kick`），listener 识别 HTTP/WebSocket/`OnMQTT` 裸 TCP，broker `Login`+`Session`，握手/断线/`OnPublishDropped` 接到 `message.App`，周期 `DispatchDue`/`PushPending`/`CleanupOnce`，下行 `PublishDown`。集成测覆盖：管理登录、写 settings 后注册、密码 MQTT 握手拿 `session_token`。  
+   - 原因：第二波收尾；三件验收必须通。  
+   - 备选方案：分文件多阶段接线。  
+   - 影响：进程可对外登录/注册/握手。
+
+2. **未接线 / 未完成部分（已被 L-UPLINK 部分取代）**  
+   - 原条款：上行应用帧完整分发到 identity/group/presence/message 业务方法。  
+   - 实际做法（L-WIRE 当时）：`Session` 处理 hello/logout；其余 `HandleUplink` 仍为 Stub。管理注册设置 HTTP（A3）未实现，测试直接写 `settings` 表。  
+   - 原因：本波强制三件验收；完整协议分发属后续波次。  
+   - 备选方案：本波同时实现 HandleUplink 大 multiplex。  
+   - 影响：见 L-UPLINK。
+
+3. **listen.addr 始终写入**  
+   - 原条款：listener N1 仅端口 0 写文件；T0.1 超集为启动即写。  
+   - 实际做法：listener 按 N1 写端口 0；serve 成功后再强制写一次 `listen.addr`（及分离时的 `admin.addr`）。  
+   - 原因：与 harness / T0.1 一致。  
+   - 备选方案：改 listener 始终写。  
+   - 影响：固定端口也会有地址文件。
+
+### L-UPLINK 2026-09-30
+
+1. **HandleUplink 分发到已有业务服务**  
+   - 原条款：TASKS 总控接线；DEVELOPMENT 第 6 节上行帧由服务端处理后回 `resp`；群事件/在线通知/消息走下行。  
+   - 实际做法：`cmd/nixmsg/uplink.go` 的 `appUplink` 在已握手连接上解码并调用 `message`/`identity`/`presence`/`group` 的既有方法；结果编成 `resp` 经 `PublishDown`（QoS 1）回本连接。`Session` 仍独占 `hello`/`self.logout` 与未握手 `not_ready`。`serve` 把四个 App 与 broker Downlink 注入 uplink。不重写业务状态机。  
+   - 原因：main 上业务实现已齐，缺上行入口。  
+   - 备选方案：各包自建 MQTT 钩子（与 port 契约不符）。  
+   - 影响：端侧 send/ack/recall/status/unlock/self.*/presence.*/directory.list/group.* 可走真实进程。
+
+2. **presence.get 未知编号编码**  
+   - 原条款：DEVELOPMENT 6.5「未知编号为 not_found」；`StatusItem.NotFound` 为内部标记。  
+   - 实际做法：`presence.EncodeGetData` 薄封装，resp data 为 `{"items":[...]}`；未知项 `{"id","not_found":true}`，已知项含 `id`/`online`/`since_ms`。  
+   - 原因：Service 层未规定 JSON 形状，接线需固定可编解码形式。  
+   - 备选方案：整请求失败 `not_found`；或把 `not_found` 塞进 `online` 旁字符串字段。  
+   - 影响：SDK 若只认 items 数组两种形状均可（Go SDK 已兼容 wrap/array）。
+
+3. **resp 超限改发 response_too_large**  
+   - 原条款：DEVELOPMENT 7.5「resp 超限改发 response_too_large」。  
+   - 实际做法：发布前按连接表 `MaxReceiveBytes` 与 `MaxPacketSize` 取较小正上限；超限则改发错误 resp（不再发原 data）。未做 MQTT 包头开销扣减（与 message 推送里的 overhead 预算不完全同一函数）。  
+   - 原因：接线层最小可用检查。  
+   - 备选方案：复用 `message.effectivePayloadLimit`（未导出）。  
+   - 影响：接近包上限的大分页可能比推送路径略严或略松。
+
+4. **断线清 presence.watch**  
+   - 原条款：presence.watch 断线清空。  
+   - 实际做法：`OnDisconnect` 额外调 `ClearWatch`；`SetOffline` 路径本身也会清。顶号旧连接未走 `SetOffline(isCurrent)` 时仍能清订阅。  
+   - 原因：避免旧连接订阅泄漏。  
+   - 备选方案：仅依赖 Session 对 isCurrent 调 SetOffline。  
+   - 影响：无。
+
+5. **仍未接线 / 本波未覆盖**  
+   - 管理注册设置 HTTP（A3）仍未挂；集成测继续写 `settings` 表开注册。  
+   - 下行通知帧（`msg`/`receipt`/`revoked`/`presence`/`group_event`/`fatal`）不是上行分发对象，由既有服务经 PublishDown 发出。  
+   - `self.logout`/`hello` 仍在 Session，不经 appUplink。  
+   - 身份 I5 停用/删除级联、管理端群等非本任务范围。  
+   - 集成测覆盖：双端单聊、离线 keep 后上线、群发不含发送者、延迟内撤回对方无回调；未穷尽 presence.watch 通知与全部 group.* 变体。

+
+1. **停用/删除级联在 identity 包内完成，admin 可选注入**  
+   - 原条款：DEVELOPMENT 7.6 / PRD F01；TASKS I5「提供给 A 线调用」。  
+   - 实际做法：`identity.App.Disable`/`Enable`/`Delete` 在一个写操作里完成启停、清令牌、作废消息/投递、发 `revoked`（可选 Downlink）、退群/转让群主/解散、清授权/回执/防重/发出记录。`admin.Deps.Identity` 非空时，`setEndpointEnabled`/`deleteEndpointBasic`（及 PATCH enabled）委托上述方法；为空时保留 A2 仅改库行为。未改 `cmd/nixmsg`、未改消息上行分发。  
+   - 原因：隔离要求不改接线；A 线已有路由，只接级联。  
+   - 备选方案：在 admin 内复制级联 SQL；或强制 Identity 必填。  
+   - 影响：生产须在挂载 admin 时注入 `identity.App`（及 KickEndpoint/ConnControl/Downlink），否则停用/删除仍无完整作废。
+
+2. **消息级作废回执 state 用 `rejected`**  
+   - 原条款：DEVELOPMENT 6.4 消息级作废写 `endpoint_id` 空、`state=rejected`；I4 解散群对 scheduled 曾写 `completed`。  
+   - 实际做法：I5 对「发给停用/删除端的 scheduled 单聊」及删除时解散群的 scheduled，回执 `state=rejected`，原因分别为 `endpoint_*` / `group_dissolved`。  
+   - 原因：与 6.4 字面一致。  
+   - 备选方案：与 I4 一样写 `completed`。  
+   - 影响：后台/SDK 若按 state 过滤回执需同时认 rejected。
+
+3. **删除时群主转让按 `joined_at` 最早，并列按编号**  
+   - 原条款：转给最早加入的其他成员。  
+   - 实际做法：`ORDER BY joined_at ASC, endpoint_id ASC LIMIT 1`。  
+   - 原因：同时加入时需稳定次序。  
+   - 备选方案：仅按 joined_at。

+### Q2 第一部分（已合并功能验收）2026-09-30
+
+1. **对真实进程探测，未接线则记「未测」而非改业务代码**  
+   - 原条款：TASKS Q2「PRD 第 10 节每条至少有一个集成测试」；本波只做已合并功能的第一部分。  
+   - 实际做法：`test/accept` 用 `test/harness`（随机端口 + 临时目录）起真实 `nixmsg`；对 `/api/admin/login`、`/api/client/register`、`POST /api/admin/endpoints` 先探测。404 则该条写「未测」并注明缺总控接线 / A2 / I 等，不修改 `cmd/nixmsg` 或业务包求绿。  
+   - 原因：main@d357082 上 A1/I1 等仅为可挂载 Handler，`serve` 只挂了 `/healthz`、`/readyz`（见各线 DEVIATIONS「未改 cmd」）。  
+   - 备选方案：测试进程内自行 `admin.New` 挂路由（不反映交付二进制行为，否决）。  
+   - 影响：本波 F17/F01/F23 多为未测；接线后同一测试会自动跑登录锁定、CSRF、注册与开通路径。
+
+2. **F22 只验收 init + 健康检查子集**  
+   - 原条款：F22 含备份恢复、升级迁移、证书重载、Docker、指标。  
+   - 实际做法：集成测试覆盖空目录 `admin init`、`serve`、`/healthz`、`/readyz`，并断言管理员密码不出现在 serve 的 stdout/stderr；其余 F22 子项仍标未测。  
+   - 原因：本波范围是「现在就能测的路径」。  
+   - 备选方案：本波强行跑 Docker/证书（超出第一部分）。  
+   - 影响：对照表 F22 为「通过」但备注写明未覆盖项。
+
+3. **验收报告写入方式**  
+   - 原条款：用 `test/report` 生成 F01–F23 对照表。  
+   - 实际做法：`TestQ2AcceptAndReport` 汇总探测结果；默认写临时目录。`task q:accept`（`NIXMSG_WRITE_ACCEPT_REPORT=1`）写入 `test/report/testdata/q2_results.json` 与 `test/accept/ACCEPTANCE.md`；`task q:report-q2` 可再生成 Markdown。普通 `go test`/`task check` 不改仓库文件。  
+   - 原因：避免每次单测改 `generated_at` 弄脏工作区。  
+   - 备选方案：固定时间戳始终写入仓库。  
+   - 影响：交付审阅以 `ACCEPTANCE.md` / `q2_results.json` 为准，需先跑过 `task q:accept`。
