## ✨ Features / 特性
| | 中文 | English |
|---|---|---|
| 🔁 | 模型流在 `llm/stream` 瀑布层透明拦截:降级模式下全缓冲 + 指数退避重试(默认最长等待 10 分钟),网络抖动不再打断回复链条 | Transparent interception in the `llm/stream` waterfall: degraded mode buffers and retries with exponential backoff (up to a 10-minute cap by default), so network blips no longer break the reply chain |
| 💾 | 完整成功响应本地缓存(请求指纹 key、LRU、TTL 可配):相同请求零 token 本地重放 | Local replay cache for fully successful responses (fingerprint keys, LRU, configurable TTL): identical requests replay with zero tokens |
| ❤️ | 断网后本地心跳任务按指数退避自动探测重连(间隔上限默认 10 分钟);任意模型流成功也立即被动恢复 | After an outage a local heartbeat task probes and auto-reconnects with exponential backoff (cap: 10 minutes by default); any successful model stream passively restores online state |
| 🪙 | 重试等待期间零模型调用(零 token);重连后可选输出上限降级与 tool-result 确定性裁剪 | Zero model calls (zero tokens) while waiting; optional output-cap and deterministic tool-result pruning after reconnect |
| 🎛️ | 24 个参数全部结构化(分组/类型/范围/默认值),设置页「弱网适配」可全部调整 | All 24 parameters are fully structured (group/type/range/default) and adjustable in the "Weak Network" settings page |
| 🌍 | 每个参数的说明与场景预期效果均为中英双语,UI 跟随系统语言 | Every parameter ships with bilingual (zh/en) descriptions and expected-effect notes; the UI follows the interface language |

## 🚀 Install / 安装
```bash
npm install dsh-plugin-weaknet-adaptor
```
Add to your composition (`cordis.yml`), e.g. in the DSH profile you run:
```yaml
plugins:
- name: dsh-plugin-weaknet-adaptor
```
The Host half activates automatically; the browser half (settings page + status dock) is
picked up through the package's `dsh.client` declaration and served by `client-modules` —
no extra wiring needed. Peer dependencies (`@deepseek-ai/*`, `cordis`) are installed
automatically by npm.
> 💡 **为什么用正式包而不是动态插件?** 动态插件(会话内 `cordis_define` 创建)只存在于进程内存,进程崩溃或重启后即丢失;本包由 `cordis.yml` 静态加载,重启后依然生效,真正"安装即用"。
>
> 💡 **Why a real package instead of a dynamic plugin?** Dynamic plugins live only in process memory and vanish on crash/restart; this package is loaded statically from `cordis.yml` and survives restarts.

## ⚙️ Configuration / 参数配置
All parameters can be changed live from **Settings → Weak Network**(设置 → 弱网适配).
Changes persist best-effort to `<workspaceRoot>/.dsh/weaknet-params.json`.
| 组 Group | 参数 Key | 类型 Type | 默认 Default | 说明与预期效果 Description & expected effect |
|---|---|---|---|---|
| 总开关 Master | `enabled` | boolean | `true` | 总开关;关闭后完全恢复原生流程。Master switch; off restores the native flow entirely. |
| 网络探测与心跳 Probing & heartbeat | `probeUrl` | string | `https://www.gstatic.com/generate_204` | 心跳探测地址;任意 HTTP 响应(含非 2xx)视为可达。Probe URL; any HTTP response (incl. non-2xx) counts as reachable. 内网/代理环境请改内网轻量端点。 |
| | `probeTimeoutMs` | number | `5000` | 探测超时(500–60000)。调小判定更快但高延迟易误报。Probe timeout; smaller = faster detection, larger = fewer false positives. |
| | `probeMode` | enum | `fetch` | `fetch`(web 服务探测)/ `off`(仅被动恢复)。`off` 用于无 fetch provider 的环境。 |
| | `heartbeatBaseIntervalMs` | number | `1000` | 探测失败后的初始间隔(200–60000)。Heartbeat base interval. |
| | `heartbeatMaxIntervalMs` | number | **`600000`** | **重连最长等待(10 分钟)**(10000–3600000)。间隔指数增长到此封顶。**Longest reconnect wait (10 min) — the interval caps here.** |
| | `heartbeatBackoffFactor` | number | `2` | 探测间隔倍增系数(1.1–5);抖动频繁建议接近 1.1。 |
| | `successThreshold` | number | `1` | 连续成功多少次判定恢复(1–10);波动网络建议 2–3。 |
| | `criticalFailures` | number | `3` | 连续失败达到该次数状态变红(离线告警),此前为黄(弱网)。 |
| 请求重试 Request retry | `maxAttempts` | number | `10` | 单个请求最大重试次数(1–100);超限按原流程终止,消息不丢。 |
| | `backoffBaseMs` | number | `1000` | 重试基础退避(100–60000)。 |
| | `backoffMaxMs` | number | `600000` | 重试退避上限(1000–3600000)。 |
| | `backoffFactor` | number | `2` | 重试退避倍增系数(1.1–5)。 |
| | `jitterRatio` | number | `0.2` | 退避抖动(0–0.5);多会话并发建议 ≥0.2 避免重试风暴。 |
| | `retryableCodes` | string[] | `TRANSPORT, TIMEOUT, STREAM_CLOSED, EMPTY_RESPONSE, MALFORMED_RESPONSE` | 视为网络故障的错误码;供应商自定义码可追加。 |
| | `retryStatuses` | number[] | `429, 500, 502, 503, 504` | 视为可重试的 HTTP 状态;勿加入 4xx 认证错误。 |
| 本地缓存 Local cache | `cacheEnabled` | boolean | `true` | 完整成功响应缓存;命中零 token 重放。 |
| | `cacheMaxEntries` | number | `50` | LRU 条目上限(1–1000)。 |
| | `cacheMaxAgeMs` | number | `600000` | 缓存有效期(1000–86400000)。 |
| 降级省 token Economy | `reduceMaxTokens` | number\|null | `null` | 降级期间输出 token 上限(100–128000);留空不限制。建议从 2000 起步。 |
| | `pruneToolResults` | boolean | `false` | 降级期间对会话 tool-result 确定性裁剪(**不可逆**),长任务接近上下文上限时开启。 |
| 界面 UI | `showStatusDock` | boolean | `true` | composer 底部信息栏显示网络状态(绿=正常、黄=弱网、红=中断)。 |
| | `statusPollMs` | number | `5000` | 状态轮询间隔(1000–60000)。 |
| 存储 Storage | `persistParams` | boolean | `true` | 参数 best-effort 持久化;写失败静默回退内存。 |

## 🧠 How it works / 工作原理
```
模型请求
│
▼
llm/stream 瀑布(本插件 prepend 挂载)
│
├─ 缓存命中? ──► 本地重放(零 token,不调 next())
│
├─ online 模式:流式转发 + 收集缓存 + 观察失败(网络类失败 → degrade)
│
└─ degraded 模式:全缓冲 → finish 判定
├─ 成功 → 写缓存 + 被动恢复 online + 整体交付
└─ 网络类失败 → 指数退避 sleep(可被取消中断)→ 重试(≤ maxAttempts)
│
▼
心跳任务(仅 degraded 时运行)
探测 probeUrl → 失败:间隔 ×factor(封顶 10 分钟)
→ 连续成功 ≥successThreshold:恢复 online
```
- **重试为何放在 `llm/stream` 而不是 `agent/request-error`?** 宿主 `llm-retry` 默认已接管 `agent/request-error`(`DEFAULT_RETRYABLE_CODES` 覆盖 TRANSPORT/TIMEOUT 等),后注册的监听器会被短路;`llm/stream` 是每个模型请求必经的瀑布,可确定性接管。`agent/request-error` 仅作降级观察。
- **缓存指纹**:`provider + model + reasoningEffort + temperature + maxTokens + stop + system + tools + messages + purpose`(键排序规范序列化)。只有逐字节一致的请求才命中。
- **不做什么**:不做工具集裁剪(动态插件沙箱白名单限制不适用于本包,但裁剪工具集会改变模型能力面,保持克制);不做流中断"前缀续传"(LLM API 不支持续传,重试即重新生成)。
- **RPC**:设置页通过 `@Remote`(`dsh-typert-protocol`)的 SRC markers 机制调用 `weaknet/*` 命名空间(`getParamDefs / getParams / setParams / getStatus / resetStats`),无需手写 typert 生成物。

## 🧪 Quick verification / 快速验证
1. 打开 设置 → **弱网适配**:状态卡 + 7 组参数(每项有双语说明与「▸ 预期效果」)。
2. 把 **心跳探测地址** 改为 `http://127.0.0.1:1/x` 并保存 → composer 底部信息栏依次变黄(弱网)→ 红(网络中断,连续 3 次探测失败),"下次探测"秒数随指数退避逐次拉长(封顶 10 分钟);改回默认 → 变绿自动恢复。
3. 切换界面语言(中/英):设置页文案即时跟随。
