fix(kernel): Close() 从不调 on_unload —— 孤儿进程与回调文件泄漏

## 症状
本机积累 **995 个 llmsproxy-loopback.py 进程**（828 个超 24 小时），全是
/tmp/Test*/ 与 .build-work/Test*/ 下的测试残留；生产 /etc/llmsproxy/plugins/
另有 **18 个孤儿 callback-*.port**（对应 .json 早已消失），且永远清不掉。

## 真因（两层）
1. **回环回收本是惰性的**：reapLoopback 只在**会话过期**时被 sweepSessions
   触发。测试跑完直接退出 ⇒ 会话从未「过期」⇒ 进程常驻。生产会话真会过期，
   所以生产不漏进程 —— 但见第 2 条。
2. **★ 根因在内核**：Plugins.Close() 只关 shard 与 saver，**从不调用
   on_unload** —— 而 on_unload 只在**单插件 Unload** 时调。于是「进程关闭/
   测试结束」这条路径上，起了 OS 进程的插件永远收不了尾。插件的
   plugin.on_unload（回收浏览器栈 + 回环）写得完全正确，只是从不被调用。
   这是「两处只修一处」缺陷的又一例：Unload 有、Close 没有。

## 修法
- 抽 invokeOnUnload(p, name) 助手，**Unload 与 Close 共用同一份实现**
  （两处各写一遍必然漂移，本次缺陷形状正是如此）；Close() 新增
  callOnUnloadAll()。
- ★ 顺序：shards.Shutdown() → save.Close()（落盘）→ callOnUnloadAll()。
  落盘必须在前 —— saver 的最终写入要读插件的 Lua 表，on_unload 之后 state
  已关，读到的就是空，最后一个区间的累积静默丢失（TestCloseFlushesTail 正是
  为守住这一点而存在）。我第一版把顺序写反，被该测试当场咬住。
- channels：启动清扫上一进程留下的孤儿 callback-*.port/.json。loopbacks
  追踪表只活在内存，进程被强杀时 on_unload 没机会跑，重启后内存表为空 ⇒
  reapLoopback 无从知晓 ⇒ 那 18 个文件永久残留。
- channels：补 reap_loopbacks 端点（生产运维也可用：不必等会话过期）。
- channels：__set_loopback_probe 从**覆盖**改为**合并**条目 —— 覆盖会丢掉
  真实会话的 pid/port_file，让 reapLoopback 杀不掉接收器，**探针自己成为
  泄漏源**（实测：其他测试已归零，只有它留 1 个孤儿）。

## 判据（均做变异验证）
- internal/lua/plugin_unload_on_close_test.go
    TestPluginsCloseCallsOnUnload      看真实外部效应（插件在 on_unload 写磁盘
                                       marker），而非「钩子被调用过」这类内部信号
    TestPluginsCloseSurvivesFailingOnUnload  best-effort 契约
- internal/core/channels_orphan_callback_test.go
    TestPluginLoadSweepsOrphanCallbackFiles  看目录真实状态：孤儿必须消失，
                                       非回调文件（.channels-store.json）不得误删
- 变异均咬住：注释掉 callOnUnloadAll → 报红；清扫改 no-op → 报红。

## 实测
修复前跑一次起会话的测试批次留 7×N 个残留进程 → 修复后 **0 个**；全量回归
（go test -tags luajit ./... 10 包）后回环/VNC 残留均为 0。

## 过程中自查出的两处疏漏（已修）
1. 判据顺序又写反一次（同上 TestCloseFlushesTail 咬住）。
2. **两枚变异残渣留在工作区**未还原：internal/gateway/discover.go 里
   `add(raw, "/models", 0)` 被删、`classifyAuthStatus` 的 `|| len(body) >= 0`
   恒真注入。已 git checkout 还原。教训：变异测试必须逐次收尾，别靠记忆。

+几点值得知道：
+
+- **URL 形态不用猜。** 厂商对「`/v1` 放 base 还是放 path」没有共识，探测会
+  依次尝试若干候选并返回答对的那个，同时给出归一化后的 `base_url` +
+  `endpoint`（`endpoint` 平时留空，因为 openai adapter 自带 `/chat/completions`）。
+- **`image_endpoint` 是另一套规则。** 网关的图像默认路径是**绝对**的
+  `/v1/images/generations`，而 chat 默认是相对的。所以 `base_url` 带 `/v1` 时
+  必须显式给 `image_endpoint: /images/generations`，否则图像请求 404。
+  探测会替你填好。
+- **图像模型只看上游自己声明的 modality**，绝不从模型名猜。`gpt-image-2`
+  这类 id 也出现在同时提供对话服务的目录上，猜错会让 AUTO 链选中一个只支持
+  图像生成的模型，其后每一层都被它拖垮。
+- **不会逐模型探活。** 34 个模型的目录跑一轮要花钱且耗时数分钟，`/models`
+  是足够便宜的信号；模型是否真能应答留给正常请求去发现。
+- **对已存在的源，必须显式 `replace_models: true`** 才会覆盖模型列表。重新

+#### 密钥用量配额
+
+**配额按模型单独设置**：每个密钥的 `models[]` 里，每一条模型范围各自带一份
+token 配额与请求数配额。一个模型用满只影响该模型，同一密钥的其它模型照常工作。
+
+```yaml
+keys:
+  - key: sk-gw-<hex>
+    role: user
+    name: agent-alice
+    models:
+      - model: deepseek-v4-flash
+        token_quota: 1000000   # 本周期内该 key 用这个模型的 token 预算
+        req_quota: 20000       # 本周期内的请求次数
+        period: nhour          # "" | hour | week | month | nhour
+        hours: 6               # 仅 nhour
+      - model: AUTO
+        token_quota: 5000000   # AUTO 也是一条独立配额
+        period: day            # ← 这种写法会被拒绝（词表只有 hour/week/month/nhour）
+      - model: kimi-k3        # 未列配额 = 无限
+```
+
+- **没有「整钥总配额」**：这是刻意的设计。整钥总额会让「把 A 模型的额度挪给
+  B 模型」变成一次全局重分配；按模型独立计费则每个模型各自可控，运维可以
+  看出哪个模型吃掉了预算。
+- `period` 词表：空 = 永不过期（累计总量），`hour` / `week` / `month` = 固定窗口，
+  `nhour` + `hours` = 自定义小时数。**拼错的周期在写入时就被拒**，不会静默变成
+  永不过期。
+- 配额严格按密钥隔离，且**同一密钥内按模型隔离**：A 密钥用满 `m1` 不会消耗
+  B 密钥的额度，同一密钥的 `m2` 也不受影响。
+- 配额统计含聊天、流式、生图，跨重启从审计日志回放（保留 40 天，覆盖最长的
+  month 窗口）。
+- 配额耗尽返回 **429 + `Retry-After`**（`rate_limit_exceeded`），消息里点名是哪个
+  模型用满了，客户端可等窗口重置后自动恢复；模型越权才是 403。
+  **admin 密钥永不受配额限制**（其 scope 上的配额也不强制），避免把管理员
+  锁在门外。
+- 窗口用量按整点小时分桶统计，实际释放比配置窗口最多晚 1 小时（配额宁可晚释放
+  也不超发）。
+- `PUT /api/keys/{key}` 提交 `models` 即同时提交它们的配额（配额就是 scope 的一部分，
+  不存在会与模型列表脱节的第二份预算）。显式 `0` = 解除该模型的限制。
+
+##### 配额拒绝 vs 容量拒绝：两种「拒绝」含义不同
+
+配额在**入口**检查，不占用任何上游槽位，因此是廉价拒绝；容量不足则要走
+`busyWait` 有界等待后才返回 503。实测（容量 8、0.6s/请求、100 并发）：
+
+| 情况 | 状态码 | 延迟 | 是否打到上游 |
+|---|---|---|---|
+| 配额用尽（`req_quota` 50 → 100 并发） | `429 rate_limit_exceeded` + `Retry-After` | **19–21ms** | 否 |
+| 容量打满（同一拓扑，未限配额） | `503 upstream_error` | ~2.6s（`busyWait`） | 超出部分否 |
+
+客户端因此可以区分「等窗口重置」与「等上游腾出容量」：前者只需等待，后者
+通常该降并发或换源。
+
+##### 配额的开销
+
+配额桶按 (密钥, 模型, 整点小时) 分桶保留 40 天，实测（AMD 7840HS）：
+
+- 窗口查询按窗口长度而非保留总量扫描：1h 窗口 49ns、24h 窗口 55ns、
+  30d 窗口 3.9μs（此前全扫保留总量，960 桶时 5.9μs）。
+- 记录一条请求：283ns、3 分配（与引入配额前相同，分配来自 ring buffer）。
+- 内存：生产形态（7 密钥 × 8 模型 × 2 源 × 满 40 天 retention）约 **3.7MB**。
+  按源 pin 的 `source::model` 桶**惰性创建**——只有当某条配额真的 pin 了
+  某个源时才维护，否则每条记录多写一份桶，在 20 密钥 × 8 模型 × 3 源下会
+  多占 18MB。
+  代价：配置 pinned 配额之前的历史用量无法事后按源拆分，所以 **pinned 配额的
+  首个窗口可能少算**。
+
+```bash
+# 配额耗尽时客户端看到（点名了具体模型）
+HTTP/1.1 429 Too Many Requests
+Retry-After: 2100

+
+```yaml

+        period: hour
+      - model: kimi-k3        # no quota listed = unlimited
+```
+
+- **There is deliberately no key-wide total.** A key-wide cap would make
+  "move A's budget to B" a global reallocation; per-model budgets keep each
+  model independently controllable, so it stays visible which model is
+  actually consuming the spend.
+- `period`: empty = never resets (lifetime total); `hour` / `week` / `month` =
+  fixed windows; `nhour` + `hours` = a custom hour count. **A misspelled
+  period is rejected at write time** rather than silently becoming a
+  never-resetting quota.
+- Quotas are isolated per key *and* per model within a key: one key exhausting
+  `m1` never draws on another key's budget, and never blocks the same key's
+  `m2`.
+- Usage counts chat, streaming and image requests, and survives a restart by
+  replaying the audit log (40 days retained, covering the longest `month`
+  window).
+- An exhausted quota returns **429 + `Retry-After`**

+  part of the scope, so there is no second budget that can drift out of sync
+  with the model list. An explicit `0` lifts that model's cap.
+
+##### Quota rejection vs capacity rejection
+
+A quota is checked at the entry point and occupies no upstream slot, so it is a
+cheap rejection. Running out of capacity instead waits out the bounded
+`busyWait` before answering 503. Measured (capacity 8, 0.6 s/request, 100
+concurrent clients):
+
+| Case | Status | Latency | Reaches upstream |
+|---|---|---|---|
+| Quota spent (`req_quota` 50, 100 concurrent) | `429 rate_limit_exceeded` + `Retry-After` | **19–21 ms** | no |
+| Capacity exhausted (same topology, no quota) | `503 upstream_error` | ~2.6 s (`busyWait`) | overflow: no |
+
+So a client can tell "wait for the window to roll over" apart from "wait for
+upstream capacity" — the first only needs patience, the second usually means
+back off concurrency or switch sources.
+
+##### What the quota costs
+
+Buckets are kept per (key, model, whole unix hour) for 40 days. Measured on an
+AMD 7840HS:
+
+- A window query scans the window, not the whole retention: 49 ns for 1 h,
+  55 ns for 24 h, 3.9 µs for 30 d.
+- Recording one request: 283 ns, 3 allocations (unchanged from before this
+  feature; the allocations come from the record ring buffer).
+- Memory: the production shape (7 keys x 8 models x 2 sources at full 40-day
+  retention) costs about **3.7 MB**. The `source::model` bucket used by a
+  source-pinned quota is created **lazily** — it is maintained only once some
+  quota actually pins that source, because writing it on every record would
+  cost an extra 18 MB at 20 keys x 8 models x 3 sources.
+  The trade-off: usage recorded before a pinned quota was configured cannot be
+  split by source afterwards, so **a pinned quota may under-count its first
+  window**.

+
+参考仓：`Ebony-Vinyl/dsh-our-free-model`（本地克隆
+`/tmp/pi-github-repos/Ebony-Vinyl/dsh-our-free-model`），关键实现位于
+`vendor/channel-pack/src/`（144 个 TS 文件）。
+
+命名规律（照它逐厂商对齐的三条线）：
+
+| 后缀 | 职责 | 我们要对齐的东西 |
+|---|---|---|
+| `X-auth.ts` / `X-oauth.ts` / `login.ts` | **登录** | 登录流程、端点、参数、凭据形状 |
+| `X-product.ts` / `models.ts` | **模型获取** | 远端端点、解析路径、兜底表 |
+| `X-adapter.ts` / `llm-adapter.ts` | **接入模型服务** | chat 端点、载荷转换、鉴权头 |
+
+## 一、登录（line ①）
+
+| 平台 | 参考流程 | 我们的 flow | 状态 |
+|---|---|---|---|

+| opencode | paste | paste | ✅（参考本身即粘贴凭据） |

+| raccoon | 二维码 poll | qr-poll | ✅ |
+
+### codearts 登录（本轮修复的重点）
+
+此前标成 `flow="paste"`（手填凭据）是**错的**。参考 `login.ts` / `oauth.ts`
+默认走**新式 IAM OAuth**：
+
+1. 起本地回调服务器，端口须 **≥10000**（`MIN_CALLBACK_PORT`，低于此 portal 拒绝），
+   路径 `/oauth/callback`
+2. 打开 `https://codearts.huaweicloud.com/portal/authorize`，参数逐项：
+   `theme=2`、`locale=zh-cn`、`uri_scheme=codearts-agent`、`client_id=codearts-agent`、
+   `code_challenge_method=**SHA-256**`（不是 RFC 的 S256 —— 错值会让 portal
+   **回退旧 ticket 流程**，看起来"也能用"但不是 OAuth）、`ticket_id`、
+   `plugin-name=snap_AIIDE`、`plugin-version=5.2.0`；
+   **不得**含 `auth_callback_url`（会被判异常并回退）
+3. 回调收到 `code` 后，带 **DPoP 证明**向
+   `https://sts.cn-north-4.myhuaweicloud.com/v1/oauth2/tokens` 换
+   `credentials{access_key_id, secret_access_key, security_token, expiration}`
+   + `refresh_token`
+4. 凭据持久化须含续期材料：`refresh_token` / `code_verifier` / `dpop_private_key_jwk`
+
+DPoP 细节：ES256 JWS，`header={alg,typ:dpop+jwt,jwk}`、
+`payload={htm,htu,iat,jti}`；**签名是 raw r||s 64 字节**，而 openssl 输出 DER
+——必须转换格式，否则服务端验签失败而字符串看起来完全正常。
+
+终态判定只认 `invalid_grant` / `ErrorCode 含 ExpiredRefreshToken`；
+**不认** `InvalidDPoPHeader`（那是一次请求层面的拒绝：时钟偏差、proof 重放、
+网关抖动都会触发，当终态会把完好账号一步标死）。
+
+旧 ticket 流程（`CODEARTS_LOGIN_BASE` + `/snap-manager/v1/login/ticket` 轮询）
+保留作回退。
+
+## 二、模型获取（line ②）
+
+远端优先、兜底补位的机制已具备（`models_remote` + `effectiveModels`）。
+本轮把**兜底表**逐平台补成参考全量：
+
+| 平台 | 参考来源 | 兜底数 | 状态 |
+|---|---|---|---|
+| trae | `TRAE_FALLBACK_MODELS` | 28 可见 + 4 hidden | ✅（hidden 单列 `models_hidden`） |
+| minimax | `GET /mavis/api/v1/models?region=cn&buildEnv=prod` | 4 | ✅ |
+| cline | `GET /api/v1/models` + `recommended-models` | 3 | ✅ |
+| buddy | （无独立表） | 7 | ✅ |
+| gemini | — | 2 | ✅ |
+| lobsterai | `GET /api/models/available`（**须带 model_flag**） | 19 | ✅ |
+| opencode | `GET /v1/models` | 14 | ✅（含 `models_free`） |
+| codearts | opengw `gateway/config` + `/v1/model/builtin` | 3 | ⚠️ 见下 |
+| qoder | `/api/v2/model/list`（需 WASM 签名） | 19 | ✅（含 CN 独有 q37fmodel/gm51model） |
+| zcode | `GET /api/v1/client/configs` | 2 | ✅ |
+| loomy | `GET /api/v1/models`（取 `type==='chat'`） | 8 | ✅ |
+| raccoon | 远端 + 兜底 | 6 | ✅ |
+
+**trae 的 `isHidden` 语义**：`browser_use_subagent` / `explore_sub_agent_v13` /
+`explore_sub_agent_v2` / `summary` 是内部子 agent，不进用户可选列表。
+`model_list` 已按此过滤（`models_hidden`）。
+
+**opencode 的 `isFree`**：参考明确标注 7 个模型匿名可用、其余需付费 key。
+此前 `model_list` 把 `isFree` 硬编码为 false，等于把官方免费模型标成付费。
+
+### codearts 模型获取（未闭环）
+
+参考 `models.ts` 从两个端点拉：
+- `OPENGW_GATEWAY_CONFIG_URL`（`opengw.developer.huaweicloud.com/api/v1/gateway/config`）
+  → `result.models`，这是 **benefit（免费额度）模型**权威来源
+- `SNAP_MODEL_BUILTIN_URL`（`/v1/model/builtin`）→ `builtinModels`，常规模型
+
+两者都要 **AK/SK 的 SDK-HMAC-SHA256 签名**。另有 `normalizeModelId`
+（去尾部 `-NNNN` 日期版本）与 `isCodeArtsBenefitModel`（决定 chat 是否带
+`maas_type: benefit`，不带则 404 `model is not registered`）。
+**这部分尚未实现**——我们的 codearts 目前只有 3 个硬编码模型名。
+
+## 三、接入模型服务（line ③）
+
+**本轮发现的最严重问题**：源注册时 `base_url + adapter.endpoint` 拼出的
+chat URL **全部缺路径前缀**，11 个平台里 11 个都不对。已逐个修正：
+
+| 平台 | 正确 chat 端点 | 修正前 |
+|---|---|---|
+| trae | `…/api/agent/v3/llm_utils_chat` | `…/chat/completions` |
+| cline | `api.cline.bot/api/v1/chat/completions` | `api.cline.bot/chat/completions` |
+| lobsterai | `…/api/proxy/v1/chat/completions` | `…/chat/completions` |
+| qoder | `api2-v2.qoder.sh/model/v1/chat/completions` | `…/chat/completions` |
+| buddy | `copilot.tencent.com/v2/chat/completions` | `…/chat/completions` |
+| codearts | `…/api/v2/chat/completions` | `…/chat/completions` |
+| opencode | `opencode.ai/zen/v1/chat/completions` | `opencode.ai/zen/chat/completions` |
+| raccoon | `…/api/web/llm/v2/chat/completions` | `…/chat/completions` |
+| loomy | `loomy.xunfei.cn/chat/completions` | `loomy.xunfei.cn` |
+| zcode | `zcode.z.ai/api/v1/zcode-plan/anthropic/v1/messages` | `zcode.z.ai/v1/messages` |
+| gemini | `/v1internal:generateContent`（私有动词） | `/v1beta/models/{model}:generateContent`（公开，凭据不匹配） |
+
+### ✅ 已闭环：三个私有协议平台改用**插件自装适配器**
+
+这是"为什么参考正常、我们不正常"的正面修复。参考每个平台是继承宿主
+`LlmAdapter` 的真类；我们此前把平台协议差异当成适配器名差异（全塞 openai）。
+内核其实**早已实现** `__llmsproxy_adapters.install`（含归属校验/冲突仲裁/
+测试），但 channels 插件对该全局的引用数是 **0**。现已第一次真正使用：
+
+| 平台 | 自装适配器 | 解决的协议差异 |
+|---|---|---|
+| codearts | `codearts` | 华为云 SDK-HMAC-SHA256 **AK/SK 签名**（canonical/string-to-sign 逐字节） |
+| trae | `channels-trae` | **SOLO 载荷**：config_name 双字段、function 通道、tool_calls→function_call、parameters→JSON 字符串、tool_choice 归一化 |
+| gemini | `channels-gemini` | 私有 `/v1internal:` **信封** + 身份五头 + 字母序序列化 + 响应剥一层 |
+
+命名说明：trae 用 `channels-trae` 而非 `trae`，因为内置 `trae.lua` 服务的是
+**运维自建的 trae-local-api 反代**（`127.0.0.1:19900`，生产 config.yaml 在用），
+与本插件的直连通道是两回事。重名会被内核冲突仲裁挂起（正确的护栏）——
+判据里专门断言内置 `trae` 未被顶掉。
+
+**新增能力：`credential_shape`**。签名平台需要**完整凭据 JSON**（适配器自己
+解 AK/SK），其余平台交裸 access token。此前 `syncAccountSource` 一律用
+`credentialOf` 取 `access_token`，于是 codearts 凭据（只有
+`access_key_id`/`secret_access_key`/`security_token`）取不到 token →
+**静默 return、不出源**。现已按 `plat.credential_shape` 区分。
+
+**另一处静默失败已修**：`syncAccountSource` 拿到内核 `add_source` 的失败
+（权限未授、形状不符）时不记日志，表现为"账号加了但不出源"，排查零线索。
+现补失败日志（区分内核 err 与 `json.ok==false`）。
+
+### 仍未闭环：gemini 的 sigstore（明确不做）
+
+参考 `gemini-sigstore.ts`（268 行）持久化 tool-call 签名，供跨请求回填。
+我们推理走**无状态适配器**，插件侧缓存会成为死代码。签名缺失时上游会拒，
+适配器如实透传错误。理由与结论已记在此处，避免反复讨论。
+
+## 四、明确不做的（附理由）
+
+| 参考模块 | 行数 | 为什么不做 |
+|---|---|---|
+| `gemini-sigstore.ts` | 268 | 推理走无状态适配器，插件侧缓存会成为死代码。签名缺失时上游会拒，适配器如实透传 ⛔ |
+| `qoder-wasm.ts` | 1442 | 需随插件分发 298KB wasm 二进制；B 类，待立项 |
+| `zcode-captcha.ts` | 2212 | 阿里云滑块，需真实浏览器/验证码链路；B 类 |
+| `captcha-*.ts` | 1223 | 同上 |
+
+## 五、本机实测踩到的坑（都已修）
+
+1. **`xxd` 不存在** —— `command -v xxd` 为空，用它取十六进制会**静默得到空串**。
+   改用 `od -An -tx1`。
+2. **`openssl ec -text` 会截断 32 字节 priv**（实测只给 30 字节）→ `d` 必须用
+   `openssl asn1parse` 的 `[HEX DUMP]`；`tail -c 32` 拿到的是 SEC1 结构里
+   **公钥的 y**，不是 `d`。
+3. **Lua local 前向引用**：`local function` 只从定义处向后可见。`hexToBin` /
+   `b64url` / `b64urlRaw` 被 CodeArts 的 PKCE/DPoP 调用，必须移到 CodeArts 块
+   **之前**（本文件累计踩过 6 次）。
+4. **`min_port` 参数读到 `argv[2]`** 与 `out_path` 冲突 —— 回调脚本的第 5 个
+   参数才是 minPort。
+5. **Lua 双引号串里的 `\1`** 是转义坑（`sed 's/…/…/\1/'` 会报
+   invalid escape sequence）→ 改用 `awk -F': ' '{print $NF}'`。
+
+---
+
+# 为什么参考插件是"正常"的：架构差异（2026-10-13 查证）
+
+用户问「为什么他们就正常」。查完参考仓的架构后，答案是**三层结构差异**，
+不是某一个端点的笔误。
+
+## 参考的架构：一个平台 = 一个适配器类
+
+参考依赖宿主 SDK 的 seam：`import { LlmAdapter } from '@deepseek-ai/dsh-llm'`。
+每个平台有一个**继承基类的真类**，同时拥有登录、模型目录、推理三件事：
+
+| 文件 | 类 | 干什么 |
+|---|---|---|
+| `trae-adapter.ts` | `TraeAdapter` | SOLO 协议转换（`config_name`/`function`，非 OpenAI 兼容） |
+| `llm-adapter.ts` | `CodeArtsAdapter` | 华为云 AK/SK 签名 + `maas_type: benefit` 判定 |
+| `zcode-adapter.ts` | `ZcodeAdapter` | Anthropic Messages 协议（非 OpenAI） |
+| `qoder-adapter.ts` | `QoderAdapter` | WASM 加密端点 + 信封剥离 |
+| `gemini-adapter.ts` | `GeminiAdapter` | `/v1internal:` 私有动词 + 字母序信封 |
+
+注册方式是 `registerAdapterIdempotent(ctx.llm, [PROVIDER], adapter)`
+（`llm-adapter.ts:2080`）。
+
+**但它不重复**：共享层是 `src/openai-compat.ts`（1196 行）——
+`serializeMessages`（消息序列化）、`consumeOpenAiSse`（SSE 消费）、
+`httpErrorCode` / `isTransportError`（错误归类）、`userContentParts`（多模态）。
+12 个 adapter 里有 8 个 `import from './openai-compat'`。
+
+即：**公共协议逻辑一份，平台差异各自一个类**。
+
+## 我们的架构：内核是 proxy，插件只注册源
+
+- 适配器是 Lua 文件（12 个），通过 4 个钩子参与：
+  `transform_request` / `transform_response` / `transform_stream_chunk` /
+  `transform_error`，外加 `build_headers`（动态签名，见下）。
+- 声明面：`endpoint` / `endpoint_stream` / `ingress` / `headers`。
+- 插件通过 `__llmsproxy_kernel.call("add_source", {source={...}})` 把平台
+  注册为上游源，`source.adapter` 引用适配器名。
+
+## 关键发现：机制早就有，但 channels 插件从没用过
+
+内核**完整实现了**插件自装适配器：
+
+```
+internal/lua/plugin_adapter_bridge.go
+  func (ps *Plugins) InstallAdapter(plugin, name, code string) (string, error)
+  registerAdapterBridge → Lua 全局表 __llmsproxy_adapters.install / .update / .remove
+```
+
+- 有归属校验（`adapterOwnership`：只能改自己装的）
+- 有冲突仲裁（影子内置/他人所有 → 挂起等运维裁决，不是硬拒）
+- 有测试证明可用：`TestPluginInstallsAdapterFromLua`（PASS）
+
+**但 `grep -c '__llmsproxy_adapters' internal/lua/plugins/channels.lua` = 0。**
+channels 插件一个适配器都没装过 —— 它只会注册 `adapter = "openai"` 的源。
+这就是"为什么我们不正常"的直接原因：**平台协议差异被当成适配器名差异**。
+
+## 我们还缺的一层：共享协议模块
+
+参考有 `openai-compat.ts`；我们没有对应物。`openai.lua` 自己写明
+「Lua adapters have no shared prelude」，`safe_tool_id` 在 `openai.lua` 与
+`anthropic.lua` 里**各复制了一份**（各 6 处引用）。
+
+所以正确做法是两层：
+1. 抽一个 Lua 共享前导（消息序列化 / SSE 消费 / 错误归类），
+   或内核在加载时注入 —— 消掉复制粘贴
+2. channels 插件为需要真协议转换的平台（trae SOLO、gemini 信封、
+   codearts AK/SK 签名）**装自己的适配器**，而不是硬塞给 `openai`
+
+### 所需的适配器能力（crypto + 出站 + 流式）
+
+已核实内核提供：
+- `sha256_hex` / `hmac_sha256_hex`（`vm.go` setupGlobals）
+- `build_headers(meta)` 收 `{url, method, body, api_key, timestamp,
+  client_session, source{name,meta}}` —— CodeArts 的 AK/SK 签名用它
+  （与参考 `signRequestHuawei` 同构，但 AK/SK 要从 `api_key` 里解出）
+- `transform_stream_chunk` 逐 chunk 调用（`provider.go:1295`）
+- 插件有完整 OS 能力（`io.popen`/`os.execute`）→ 可用 openssl 做 EC 签名
+
+### 未验证的风险
+
+- 适配器 VM 能否访问 `__llmsproxy_secrets`（AK/SK 要解出 SK 才能签名）
+- 流式转换能否跨 chunk 保持状态（trae 的 SSE 需要跨帧累积 tool_calls）
+
+这两条是下一步落地前必须先探的。

+
+# 插件自装适配器：机制与判据（2026-10-13）
+
+## 机制（内核早已具备，本轮才开始使用）
+
+```
+internal/lua/plugin_adapter_bridge.go
+  InstallAdapter(plugin, name, code)   # 含归属校验、冲突仲裁（影子内置 → 挂起等裁决）
+  registerAdapterBridge → Lua 全局 __llmsproxy_adapters.install / .update / .remove
+```
+注册点在 `bootPluginState`，**先于** `DoString(code)` —— 所以插件在脚本执行期
+就能装适配器。适配器装在**适配器 VM**（与插件 VM 分离，各自独立）。
+
+## 三条能力（实测，不是推断）
+
+`internal/lua/plugin_adapter_capability_test.go` 锁死：
+
+| 能力 | 结论 | 为什么关键 |
+|---|---|---|
+| 拿凭据 | 适配器**能**经 `build_headers` 的 `meta.api_key` 拿到（`url`/`method`/`body` 也在） | AK/SK 签名的前提；同时**验不到** `__llmsproxy_secrets`（只注入插件 VM，安全边界完好） |
+| 流式状态 | `transform_stream_chunk` **跨 chunk 保持同一 Lua 状态**（表地址恒定） | SOLO 跨帧累积 tool_calls、gemini 跨帧剥信封的前提 |
+| 加密原语 | 适配器可用内核 `sha256_hex` / `hmac_sha256_hex`（用标准向量校验） | 签名不需要外部进程 |
+
+## 踩过的坑（都是"静默失败"类，值得记）
+
+1. **`function` 是 Lua 关键字** —— 写 `body.function = x` 是**语法错误**
+   （`'<name>' expected near 'function'`），必须 `body["function"]`。
+   插件脚本本身能编译通过，**只在适配器 `load()` 时才暴露**。
+2. **Lua 长字符串里不能有字面 NUL 字节** —— 报
+   `unfinished long string near '<eof>'`，且**报在文件末尾**，完全指不到现场。
+3. **本 Lua 构建不支持按位异或 `~`**（`unexpected symbol near '~'`）。
+4. **装载失败只回"源码无法编译"、不给行号** —— 三个自装适配器现统一加
+   **本地预编译护栏**（先 `load` 一次拿行号）。上面三个坑都是靠它定位的。
+5. **抽公共代码要抽最全的实现**。前导重构时我先抽了 `transform_error` 的
+   最小版（只认 `{error:{message}}`），打挂 6 个既有测试 —— 最小版丢掉了
+   HTML 错误页、裸文本、扁平 `{code,message}`、FastAPI `{detail}`。
+   抽最小实现是**静默降级**：不报错，只是少认几种错误体。
+6. **判据必须能看见真实函数的返回值**。我一度用 `kernelTestCore` 裸加载插件
+   （没授 `add_source` 权限）测源注册，源一直不出；直到把内核原始返回
+   （`kernel action add_source is not granted to plugin channels`）带出来才
+   定位。**黑盒断言只在失败时告诉你"不对"，不告诉你"为什么"**。

+# 生产实测：不可用的真相（2026-10-14）
+
+## 症状与根因
+
+用户报"完全不可用"。实测（`/api/plugins/http/channels/account/list` 逐平台）：
+
+| 平台 | 账号数 | **有凭据的** |
+|---|---|---|
+| buddy | 2 | **1** |
+| trae | 3 | 0 |
+| minimax | 1 | 0 |
+| lobsterai | 1 | 0 |
+| codearts | 5 | 0 |
+| 其余 7 平台 | 0 | 0 |
+
+**13 个账号里只有 1 个真有凭据**，其余全是**占位壳子**（`has_credential: false`）。
+占位账号不是"已登录"，它只是为「先建账号行、登录后填凭据」这个两步流程预留的
+行。此前的判断只看「12 平台 0 个 manual」，那是**错的判据** —— manual 是
+flow 类型，不是"登录成功"。
+
+## 排除项（都实测过，不是猜）
+
+| 检查 | 结果 |
+|---|---|
+| 服务状态 | `active`，`NRestarts=0` |
+| 部署一致性 | 4 个插件 sha256 与仓库**全部一致**；关键标记（installCodeartsAdapter / installTraeAdapter / installGeminiAdapter / sorted_json / sign_parts）全部在位 |
+| **推理链路** | `POST /v1/chat/completions` 实测返回 `"OK"`（走 buddy 源、deepseek-v4.1-flash）—— **网关本身完全可用** |
+| 登录机制 | minimax 真实返回 `user_code=T49S-RC7G` + 验证地址；trae 起了服务端浏览器 + 回环回调 |
+| 设备码轮询 | 5 次全部 `pending`（未授权时**不误判**为失败或成功 —— 这是正确行为） |
+
+## 结论：不是代码坏了，是**授权没完成**
+
+剩下的 12 个平台都需要**人工动作**才能走完登录：
+
+- **device-poll**（minimax / cline / qoder）：把 `user_code` 拿到
+  `account.minimax.cn/oauth-authorize` 之类的**官方页面**输入
+- **callback**（trae / gemini / lobsterai）：在 **VNC 窗口**里点授权
+  （回环回调只能由本机解析，远程浏览器永远接不住）
+- **qr-poll / wechat-poll**（raccoon / loomy）：扫码
+- **init-poll**（zcode）：授权页 + 可能的验证码
+
+这些**按设计就必须人工**，assistant 无法独立端到端完成。
+
+## B 类：实测结论
+
+| 项 | 行数 | 结论 |
+|---|---|---|
+| qoder-wasm + envelope | 706 + 226 | **二进制不在仓库**（`find -name '*.wasm'` 为空，属构建产物）。没有 `qoder-auth-wasm.wasm` 无法实现；拿到才有意义 |
+| zcode-captcha + carrier | 2119 + 93 + 280 + 206 | 阿里云滑块。且**登录本身不需要它** —— captcha 只用于**签到/领取**环节（`zcode-auth.ts:22-23`：claim 时每个 plan 单独 mint captcha）。登录闭环不受阻，受阻的是自动领取 |
+| captcha-pool | 280 | 同上，服务于领取环节的验证码供给 |
+
+**修正判断**：B 类不是"登录闭环的拦路虎"。zcode 的登录（`/api/v1/oauth/cli/init`
+→ poll）不需要验证码；captcha 只在**自动领取**时出现。所以 B 类的真实价值是
+"让领取全自动"，而不是"让平台可用"。

+
+# 真实数据事故：测试覆盖了生产账号池（2026-10-14）
+
+## 症状
+
+用户报「完全不可用」。逐平台 `account/list` 后发现：**13 个账号里只有 1 个有凭据**，
+其余是占位壳子；再查发现**账号池被清空了**（`pool` 全为空 `{}`），
+而保险库 `.secrets/channels.json` 里的凭据**还在**。
+症状正是「账号凭空消失」。
+
+## 根因（实测输出，非推断）
+
+channels 插件用 `storeDir()` 决定存储位置，它有多级兜底：
+
+```
+env LLMSPROXY_PLUGIN_DIR → settings.store_dir → 读 /etc/llmsproxy/config.yaml 的 plugin_dir → 硬编码
+```
+
+测试台没设 `LLMSPROXY_PLUGIN_DIR`，**后两级直接命中生产**：
+
+```
+测试插件目录 = /tmp/TestXXX/002/plugins
+storeDir 结果 = /etc/llmsproxy/plugins          ← 探针实测输出
+```
+
+于是测试加载真 `channels.lua` 时**读的是生产存储、写的也是生产存储**。
+一次全量 `go test ./internal/lua` 就把
+`.channels-store.json` 从 1730 覆盖成 1986 字节、账号池清空（inode 都换了）。
+
+只有 `internal/lua` 复现，`internal/core` 不复现 —— 因为 core 的测试台
+（`kernelTestCore`）设了 `LLMSPROXY_PLUGIN_DIR`。**这是隔离做得不一致**的代价。
+
+同类前科：曾把 26 个测试账号写进生产 store。两次同一类错误。
+
+## 为什么 `DisableStatePersistence` 不够
+
+第一版修复给 `runtimePlugins` 关了持久化，**仍然复现**：插件声明了 `schedule`
+时内核会自动起调度器（`plugins.go: p.Runtime = ps.startRuntime(...)`），
+真 channels 的 `refresh_models` 会在 5s 后（first_due_now）跑一轮并
+`logEvent → markDirty`。那是**后台 goroutine，比 `t.Setenv` 的生命周期长** ——
+测试结束后它仍可能落盘，此时环境变量已还原。
+
+## 修法（两层，第二层才是根治）
+
+1. **内核把插件的真实目录交给插件**（ground truth，不再靠猜）：
+   新增 `__llmsproxy_plugin_dir` 全局（`registerPluginDirBridge`），
+   `storeDir()` 优先用它。**即使没有环境变量也不会落到生产路径** ——
+   实测：撤掉 env 后 `storeDir` 仍落在临时目录。
+2. 测试台补隔离：`runtimePlugins` 设 env + `DisableStatePersistence()`。
+
+## 判据 + 变异验证
+
+`internal/lua/store_dir_isolation_test.go`：
+`storeDir` 绝不能是 `/etc/llmsproxy` 前缀、必须落在临时目录、env 必须真的被设。
+**变异验证**：把隔离设成生产路径 → 判据变红并打印「storeDir 指向了**生产**目录」；
+恢复 → 变绿。
+
+全量回归：9 个包全绿，且 `go test ./...` 后生产存储**未被改动**（此前必被改）。
+
+## ⚠️ 修复过程中我自己踩的坑
+
+恢复账号时我把**保险库文件里的密文**当成明文，喂给 `account/add` 的
+`credential` —— 保险库 `loadSecretsLocked` **会在读取时解密**，于是那份凭据被
+**二次加密**（1971 → 2965 字符），该账号的推理开始返回空
+（`codebuddy_*` 源失效，而非池路径 `channels:buddy` 正常）。
+
+教训：**凭据只能由登录/续期路径写入，绝不要手工把密文塞回 API**。
+要复用既有凭据，应走「让插件自己读保险库」的路径，或者重新登录一次。

+另修 3 个**静默失败**：`account_test` 不发请求、业务级错误（HTTP 200 + body 带

+
+## 仍未实现（按影响面排序）
+
+| 模块 | 行数 | 为什么不做的理由 / 阻塞 |
+|---|---|---|
+| `zcode-captcha` + 6 个 captcha-* | ~3345 | 阿里云滑块。**登录不需要它** —— captcha 只在签到/领取环节（`zcode-auth.ts:22-23`）。真实价值是"让领取全自动"而非"让平台可用" |

+| `zcode-identity` / `transport` / `diagnostics` | 1104 | 设备身份 + 传输层 + 错误诊断。与 captcha 链路耦合 |
+| `account-pool` / `channel-pack-store` | 1912 | 我们已自建（形态不同，非缺口） |
+| `opencode-proxy` / `opencode-rpc` | 530 | 多出口代理（NAT 后多机共享出口时按 IP 限流才需要） |
+| `message-shape` | 146 | **不适用**：那是 DSH 宿主的消息形状迁移（0.1.5→0.1.7）。我们的适配器直接透传 OpenAI 形状，无此问题 |
+| `loop-recovery` | 346 | **前提不存在**：它做的是"循环守卫中止后自动续跑"，而我们的内核**没有循环守卫** |

+**未实现的部分集中在两类**：(1) 需要**真实浏览器/验证码**的领取全自动

+

+
+# 第三批（2026-10-14 晚）—— 逐模块对照的**新发现**
+
+## ★ 本轮新补的三个真缺陷
+
+### ① 自动领取每天静默漏领（`credits.ts` / `auto-checkin.ts`）
+活动刷新时刻**各平台不同**（Qoder 每日 10:00 UTC+8），而我们只在 08:00 跑一次
+⇒ 上午看到昨天那条 `CLAIMED`、报 `already-claimed` 并记账 ⇒ 当天再不去领。
+**修法照参考**：不配"时刻表"（必然漂移），让**产出方声明 `covers_today`**，
+记账方只数"有几条能证明今天已处理"。两层都要：频率提高 + `first_due_now`。
+
+### ② 凭据续期此前是假的（`refresh.ts` / `expiry-sync.ts`）
+`account_refresh` **一个换 token 的请求都不发**却恒返回 `ok:true`
+⇒ `refresh_creds` 打「已续期 N 个」而什么都没续 —— **日志在说谎**。
+这是本轮第三次遇到同形态（前两次：`account_test` 恒 ok、业务级错误被当成功）。
+
+### ③ `isFree` 与声明自相矛盾（`cline-models.ts`）
+cline 的免费模型声明在 `models` 里 ⇒ 被标成收费。
+★ 关键认识：**两个参考用的是不同机制** —— cline 用远端 `free[]`，
+opencode 用 models.dev 的 `cost`。混成一条 OR 链会与既有判据正面冲突。
+⇒ 加 `free_source` 由**平台声明**权威来源。
+
+## 插件自装适配器（第 3、4 个）
+| 适配器 | 解决的问题 |
+|---|---|
+| `channels-qoder` | 错误信封**双层编码**；`10605`(排队) 与 `110`(额度耗尽) 语义**相反**，必须分开说（参考实测：110 原被归成通用服务端错误 → 白重试 5 次 ≈15.5 秒） |
+| `channels-cline` | 429 **无 retry-after 头**、等待时长写在英文句子里（`Try again in 19h 39m`）。解析不出 ⇒ 内核按 30 秒短冷却 ⇒ **每 30 秒猛敲上游**（比参考的「永远 60 分钟」更糟） |
+
+现共 4 个：`channels-trae` / `channels-gemini` / `channels-qoder` / `channels-cline`。
+
+## 对照后判定「不适用」的（附理由，不是"没做"）
+
+| 模块 | 为什么不需要 |
+|---|---|
+| `account-pool` 并发写竞态 | 我们的落盘是**同步** tmp+rename（Lua 无异步），每次写序列化**当前** state。参考的缺陷是"异步后端 + 共享可变快照"的产物。**已加判据钉住**（已删账号不复活、新增不丢失、内存/磁盘不分叉） |
+| `gemini-messages` SSE 末帧丢失 | 我们的 `bufio.Scanner` 对无尾换行的最后一行**照样产出**（已实测自证）。参考那是在 `while(!done)` 里按行处理所致 |
+| `cline-rate-limit` 的 30 分钟策略冷却 | 我们**每账号一个源**（`channels-<plat>-<acct>`）⇒ 某账号被拦只冷却它自己，下个请求自然换源。参考是"一个池里换号"，才需要长冷却挡住同一轮里的连续重撞 |
+| `message-shape` | DSH 宿主的消息形状迁移；我们直接透传 OpenAI 形状 |
+| `loop-recovery` | 前提不存在（我们的内核没有循环守卫） |
+| `reasoning-ladder` | 需要内核支持 `efforts` 字段（属内核改动，按纪律不做） |
+| `retry-after.ts` | 参考那份实现**自己就是死代码**（grep 无消费者）；我们的固定 30s 冷却有明确理由（429 是"太快"不是"坏了"，走指数退避会让额度充沛的源被锁 30 分钟） |
+| `image-budget` | 实际缩放委托给宿主的附件服务，我们无对应物 |
+
+## 运行环境的一条教训（不是代码缺陷）
+全量 `go test` 曾出现 `TestConcurrentPluginAdapterUpdates` **挂 59 分钟**、
+看着像死锁。单独跑 **0.058s 通过** ⇒ 真因是 **`/tmp`（8.8G tmpfs）被 Go 构建
+缓存占满 100%**。教训：构建/测试挂住时先 `df -h /tmp`（`/` 空闲不代表 `/tmp` 够）。

+# 插件可调用内核动作（R4-c）设计
+
+> 用户决策（2026-10-11）：**全开**（13 个内核动作全部可调）+ **设置页可配权限** +
+> **Go 侧 deadline 兜底**。
+
+## 1. 要解决的问题
+
+用户原话："现在这个接口不全，可以多给一些接口让 lua 调用内核。"
+
+现状（`__llmsproxy_adapters`）是我手写的**三个闭包**（install/update/remove），
+只能管适配器。内核还有 13 个公开动作（Reload / ResetHealth / AddSource /
+RemoveSource / SaveAutoRules / key 增删改 / 列表读取…），插件一个都调不到。
+
+而"自动孵化 / 自愈 / 联动"这类插件能力（例如：探测到上游全挂 → 触发重探 +
+清冷却；发现额度变化 → 重排 AUTO 链）恰恰需要它们。
+
+## 2. 关键认识：Go 调用可以超时，Lua 死循环不能
+
+这决定了整个设计，也是用户提"阻塞 + Go 兜底"的原因：
+
+| 形态 | 能否中断 | 处置方式 |
+|---|---|---|
+| Lua 里 `while true do end` | **不能**（LuaJIT 限制，已实测三次） | 只能停用插件 |
+| Lua 里 `__llmsproxy_kernel.call("reload")` | **能** | Go 侧 `select` + deadline，超时把错误返回给 Lua |
+
+因为 Lua 只是在等 Go 的返回值，**不占用 Lua 栈的执行**。所以给每次内核调用加
+Go 侧 deadline 是可行的、干净的 —— 不需要"Lua 投递请求、Go 队列执行"：那样
+还要定义"超时后队列里积压的命令怎么办"，而 deadline 直接返回 `(nil, err)`，
+语义闭合。
+
+## 3. 依赖方向
+
+`internal/lua` **不能** import `internal/core`（方向是 core → lua）。
+按既有先例（`SetOutboundHosts`）注入一个**接口**，由 core 实现：
+
+```go
+// internal/lua/kernel_api.go
+type KernelAction struct {
+    Name        string   // "reload" / "reset_health" / ...
+    Title       string   // 设置页展示用
+    Description string
+    Danger      string   // ""=只读, "write"=改配置, "danger"=破坏性
+    Params      []string // 参数名（设置页/文档用）
+}
+
+type KernelAPI interface {
+    // Actions 列出可调用动作（设置页据此渲染权限开关）
+    Actions() []KernelAction
+    // Invoke 执行一个动作，args 为已解码参数。**必须**尊重 ctx 的 deadline。
+    Invoke(ctx context.Context, name string, args map[string]any) (any, error)
+}
+```
+
+core 侧实现 `Invoke` 时用**现有的 Core 方法**，本身不持 `p.mu`，因此不会与
+插件锁成环（已核实：所有 `ps.mu` → `p.mu` 都是先释放 `ps.mu`）。
+
+## 4. 权限模型
+
+复用 `visibilityOverrides` 的**同一套持久化机制**（`.access.json`），
+但用独立的键空间：`kernel:<plugin>` → 逗号分隔的动作名或 `*`。
+
+- **默认拒绝**：插件不显式获得授权时，`call` 返回 `(nil, "not permitted")`。
+  理由：全开是"能力存在"，不是"默认授予"。一个插件能删密钥这件事必须由
+  运维在设置页点过确认。
+- **`danger` 类必须显式逐个授权**，不接受 `*`。这一条是防止运维图省事写
+  通配符，把"删密钥"和"读状态"等同起来。
+- 插件可以在自己源码里**声明**它想要的动作（`plugin.kernel = {...}`），
+  设置页把它显示为"申请"，运维批准后才生效。声明不等于授权。
+
+## 5. 动作清单（13 个 + 适配器 3 个）
+
+| 动作 | 危险级 | 对应 Core 方法 | 超时 |
+|---|---|---|---|
+| `status` | 只读 | 读 AutoSlotStates/Registry | 2s |
+| `list_sources` | 只读 | Sources() | 2s |
+| `list_models` | 只读 | Registry().ModelList() | 2s |
+| `list_adapters` | 只读 | ListAdapters() | 2s |
+| `adapter_owner` | 只读 | AdapterOwnerOf | 2s |
+| `reload` | write | Reload() | 30s |
+| `reset_health` | write | ResetHealth() | 5s |
+| `probe_all` | write | Registry().ProbeAll(ctx) | 60s |
+| `save_auto_rules` | write | SaveAutoRules() | 10s |
+| `save_key_auto` | write | SaveKeyAuto() | 10s |
+| `add_source` | write | AddSource() | 30s |
+| `remove_source` | danger | RemoveSource() | 30s |
+| `create_key` | write | CreateKey() | 10s |
+| `update_key` | write | UpdateKey() | 10s |
+| `delete_key` | danger | DeleteKey() | 10s |
+| `install_adapter` | write | UploadAdapter() | 10s |
+| `remove_adapter` | danger | RemoveAdapter() | 30s |
+| `set_plugin_enabled` | danger | SetEnabled() | 5s |
+
+**绝不开放**：`ListKeys()` / `FindKey()` —— 返回**明文密钥**。给插件读密钥等于
+把网关的凭据面交给第三方 Lua。要用 key 相关动作就只用带掩码的形态。
+
+## 6. Lua 调用面
+
+```lua
+-- 探测：拿到可用动作与自己的授权情况
+local acts = __llmsproxy_kernel.actions()
+-- 调用：统一入口，返回 (result, err)
+local ok, err = __llmsproxy_kernel.call("reset_health", {})
+local st, err = __llmsproxy_kernel.call("status", {})
+```
+
+统一入口（而不是每个动作一个全局函数）的理由：动作集合将来会变，而
+`__llmsproxy_kernel` 的签名不变 —— 否则每加一个动作就要动
+`bootPluginState`，而那里正是历史上出过 cgo 崩溃的地方。
+
+## 7. 实施顺序
+
+1. `internal/lua/kernel_api.go`：接口 + 动作元数据 + 权限检查 + deadline 包装
+2. `internal/lua/plugin_kernel_bridge.go`：Lua 绑定（`actions` / `call`）
+3. `internal/core/kernel_actions.go`：实现 `KernelAPI`（core 侧）
+4. 权限持久化：复用 `.access.json`，新键空间
+5. 设置页：插件行加"内核动作"列 + 授权编辑
+6. 测试：Go 侧全动作、Lua 侧调用、权限拒绝、deadline 生效、危险动作需显式授权

+
+默认情况下，网关把适配器产出的**统一格式**按 OpenAI 线格式序列化给下游（这是内核
+保留的兑底，R5）。当上游协议不是 OpenAI（例如 Anthropic Messages API）时，适配器
+可以接管出向序列化，自己决定写给客户端的字节。
+
+五个钩子都是可选的，**全不声明就沿用 OpenAI 兑底**。一旦声明某个钩子，它就完全
+接管那一段输出——内核不会再往里混合 OpenAI 字段（不是“叠加”，是“取代”）。
+
+| 钩子 | 何时被调用 | 返回值 |
+|------|-----------|--------|
+| `serialize_response(payload)` | 非流式响应 | 写给客户端的响应体字符串 |
+| `serialize_open_preamble(payload)` | 流式开始（发第一个 chunk 前） | 要发的字节（可为 `""`） |
+| `serialize_chunk(delta)` | 流式每个增量 | 要发的字节（`""` 表示跳过） |
+| `serialize_close(payload)` | 流式结束 | 收尾字节（如 SSE `message_stop`） |
+| `serialize_done_marker(payload)` | 流式结束处的 `[DONE]` 标记 | 要写的字节；不声明则用 OpenAI 的 `data: [DONE]` |
+
+`payload` 是统一格式的结果表（见 `internal/types/maxwire.go` 的 `UnifiedResult` /
+`UnifiedDelta`），字段名中立，不依赖具体上游协议。
+
+```lua
+-- anthropic.lua 的简化形式：把统一结果写成 Anthropic Messages 形状
+function adapter.serialize_response(payload)
+  return json.encode({
+    id = payload.id,
+    type = "message",
+    role = "assistant",
+    content = { { type = "text", text = payload.content or "" } },

+    usage = { input_tokens = payload.prompt_tokens, output_tokens = payload.completion_tokens },
+  })
+end
+```
+
+注意：钩子返回的是**完整要发送的字节**（包括必要时的 `event:` / `data:` 前缀与
+空行），因为只有适配器知道目标协议的 SSE 细节。
+
+### 入向让出钩子（契约 v2，`serialize_*` 的对偶）
+
+出向是「统一格式 → 客户端协议」，入向是它的镜像：「客户端协议 → 统一格式」。
+内核为对外端点（如 `POST /v1/messages`）**保留一份内置解析作为兜底（R5）**，
+但适配器可以**声明自己服务该端点**并接管解析——那时内核主动让出，客户端协议的
+迭代就完全落在适配器里，不再需要动内核。
+
+声明分两步：
+
+1. `adapter.ingress = "/v1/messages"` —— 声明**认领**哪条对外入站路径。
+   同一条路径被多个适配器认领是配置错误；内核按适配器名字典序确定性选择。
+2. `deserialize_request(raw_body) -> unified_json` —— 把客户端原始 body 解析成
+   统一请求（`UnifiedRequest` 的 JSON），后续调度与 `/v1/chat/completions` 完全一致。

+ModelRouter 的插件是**单个 `.lua` 文件**，放在 `config.yaml` 的 `plugin_dir` 目录里。
+插件能做两件事：
+
+1. **挂钩子**：在请求流水线的若干 stage 上注册回调，看到每个请求的完整信息，
+   并可以把结果累加进自己的状态。
+2. **贡献界面**：在启动时返回 HTML / CSS / JS，由内核注入 WebUI——可以是一整个
+   新页面，也可以是往现有页面里追加一个组件。
+
+两者互相独立：只想统计请求数的插件不必碰界面；只想加个仪表盘的插件不必碰钩子。
+
+---
+
+## 1. 快速上手
+
+一个最小的插件：
+
+```lua
+-- plugins/hello.lua
+local plugin = {
+  name = "hello",
+  version = "1.0.0",
+  description = "示例插件",
+  author = "you",
+}
+
+-- 声明钩子
+plugin.hooks = {
+  request_end = "on_request_end",
+}
+
+-- 钩子实现
+function plugin.on_request_end(payload)
+  -- payload 是解码后的 table，不是 JSON 字符串
+  log("info", string.format("%s via %s: %d prompt tokens",
+    payload.model, payload.source, payload.prompt_tokens or 0))
+  return nil  -- 最后一个 stage 没有下游，return 无意义
+end
+
+-- 贡献界面
+plugin.ui = {
+  page = {
+    page_id = "hello",     -- kebab-case
+    title = "Hello",
+    icon = "",
+    order = 90,            -- 侧栏排序
+    mount = [[<div id="hello">hello</div>]],
+  },
+}
+
+return plugin   -- 必须返回一个 table
+```
+
+放进 `plugin_dir` 后重启即生效。`GET /api/plugins` 确认它被加载了。
+
+---
+
+## 2. 加载与生命周期
+
+```
+core.New
+  └─ lua.NewVM(adapter_dir).Start()        适配器状态
+  └─ lua.NewPlugins(vm, plugin_dir)
+       ├─ SeedBundled()                    仅当目录不存在时写入内置插件（目前是 billing）
+       └─ LoadDir()                        按文件名字典序逐个加载
+```
+
+**加载失败不影响网关启动。** 一个语法错误的插件会被记录在 `GET /api/plugins`
+的 `error` 字段里，永远不会被调用。这与适配器一致，但理由更强：插件是可选的
+第三方扩展，因为一个 `.lua` 打错字就让网关起不来是错误的取舍。
+
+**目录一旦存在就是权威的。** 与适配器同规则：首启会 seed 内置插件，之后目录里
+的文件说了算，删除或编辑内置插件都是真实生效的操作。
+
+### 2.1 热更新
+
+| 方式 | 效果 |
+|---|---|
+| `POST /api/plugins {name, code}` | 写文件 + 立即加载新版本（旧的 Lua 状态被关闭重建，**累计量清零**） |
+| `DELETE /api/plugins/{name}` | 删文件 + 卸载 |
+| 改文件后 `POST` 同名 | 同上 |
+
+改文件但**不** POST，需要重启才生效。
+
+---
+
+## 3. 流水线 stage
+
+一个请求依次经过三个 stage。插件可以为任意 stage 注册钩子；未注册的 stage
+被忽略，所以插件不会因为网关将来新增 stage 而报错。

+### 3.1 触发点在哪
+
+| stage | 代码位置 | 说明 |
+|---|---|---|
+| `request_start` | `gateway/chat.go` `handleChat` / `fireImageStart` | 每个请求一次（chat 与生图各一条），在配额闸门**之前** |
+| `chain_step` | `gateway/chat.go` `chainTraceSink` | **仅 AUTO 路径**，每步一次 |
+| `routed` | `singleChat` / `streamChat` / `singleChatAuto` / `streamChatAuto` | 成功选定源之后，各一次 |
+| `request_end` | `gateway/chat.go` `writeRec` | **所有出口的唯一汇合点**，每个请求一次 |
+
+### 3.1b 为什么单独有 `chain_step`
+
+`routed` 只在**遍历结束后**触发一次，只带最终胜出的槽位。所以
+"tier 1 冷却所以降级到 tier 3"和"tier 1 正常接单"在它眼里**完全一样**——
+而这恰恰是优先级链存在的全部理由。
+
+`chain_step` 补上这条信息，四种 `kind`：
+
+| kind | 含义 | 何时产生 |
+|---|---|---|
+| `tier_skip` | 整档被跳过 | 该档所有槽位冷却中/配额用尽 |
+| `slot_fail` | 某个槽位硬失败 | 上游报错 / 适配器输出不可用 |
+| `tier_busy` | 整档全忙且有界等待超时 | 2s 内没等到空位 |
+| `selected` | 这个槽位接了单 | 每次成功遍历**恰好一次**，且是最后一步 |
+
+顺序保证：所有 `chain_step` 都在 `routed` 之前，`selected` 是最后一步。
+所以只订阅 `request_end` 的插件也能拿到轨迹摘要（见下）。
+
+### 3.1c `request_end` 里的轨迹摘要
+
+除了逐个 `chain_step`，`request_end` 还带三个便于做报表的字段：
+
+| 字段 | 含义 |
+|---|---|
+| `chain_walk` | 整个遍历的步骤数组（上限 12 步，超出截断） |
+| `degraded` | 布尔。`true` = 有过跳过/失败，即**发生了降级** |
+| `tier_served` | 实际服务的那一档；直连或全失败时为 `-1` |
+
+> **计费口径**：按**实际服务的模型**计费。降级到 tier 3 仍按 tier 3 的价算，
+> `chain_step` / `degraded` / `tier_served` 只作**观测**，不参与计价。
+> 理由见 §7.5。
+
+`request_end` 放在 `writeRec` 是因为四条入口路径（直连/AUTO × 流式/非流式）都
+经过它，既不会漏（流式的 token 数只有流结束才知道），也不会重复。
+
+**hot path 注意事项**：没有插件注册某 stage 时，`Fire` 立刻返回（一次 `RLock`
+加一次 map 查找）。装了插件之后，每个请求会在该 stage 上多一次 Lua 调用——
+这是同步的，在关键路径上。计费插件那种"每请求一次"是正常的；把重活放进钩子是
+反模式。
+
+### 3.2 钩子的返回值
+
+- 返回 `nil` 或不返回 = **没有意见**，payload 原样传给下一个插件
+- 返回 table = 其中的键会**合并进 payload**，并作为 `Fire` 的返回值
+
+**同一 stage 的多个插件并行执行**，但返回值按**插件加载顺序**合并，所以结果是
+确定的（不依赖 goroutine 调度）。代价是一个插件看不到另一个插件刚加的字段：
+每个钩子拿到的是**同一份 payload 快照**。
+
+这与早期版本不同 —— 早期是顺序执行，后一个插件能看到前一个的返回值。它从未被
+实际依赖（随核心发布的 billing 在每个 stage 都 `return nil`，注释里写着
+"nobody downstream would read a return value"），但这是一处**契约变化**：如果你的
+插件依赖「读到前一个插件写的字段」，并行的两个插件之间必须改用外部通信
+（例如各自写 `plugin.state`，由 `/api/plugins/<name>/state` 读取）。
+
+单个插件时不启 goroutine，直接调用。
+
+前三个 stage 的返回值目前没有内部消费者（最后一个 stage 之后就是写审计），
+所以计费插件改用 `plugin.state` + `/state` 端点来暴露数据。
+
+---
+
+## 4. 界面扩展
+
+### 4.1 整页
+
+```lua
+plugin.ui = {
+  page = {
+    page_id = "billing",   -- 必填,kebab-case。侧栏 data-tab 与 #tab-billing
+    title = "Billing",     -- 必填,侧栏文字
+    icon = "",           -- 可选
+    order = 40,            -- 侧栏排序,默认 100
+    mount = [[...HTML...]],
+  },
+}
+```
+
+### 4.2 往现有页面追加元素
+
+```lua
+plugin.ui = {
+  elements = {
+    {
+      target = "status",   -- status | chat | keys | sort | sources | adapters
+      anchor = "top",      -- "top" | "bottom" | "before:<sel>" | "after:<sel>"
+      order = 5,
+      mount = [[...HTML...]],
+    },
+  },
+}
+```
+
+### 4.3 `mount` 里可以带 `<script>` 和 `<style>`
+
+内核的注入顺序是：**先插 HTML，再执行 `<script>`**，所以脚本里访问
+`document.getElementById` 一定能拿到已渲染的节点。
+
+### 4.4 插件可用的浏览器端 API
+
+| API | 作用 |
+|---|---|
+| `window.pluginAPI.fetchState(name)` | 等价于 `GET /api/plugins/<name>/state` |
+| `window.pluginAPI.onTabShown(fn)` | 注册"页面切到可见时"的回调（轮询类组件用） |
+| `window.pluginAPI.postState(name, obj)` | `PUT` 自己的 state（写操作，需 admin） |
+
+### 4.5 一个完整例子
+
+见 `internal/lua/plugins/billing.lua`——它同时用了两种 UI 形式、完整的价格配置、
+以及全部三个 stage。
+
+---
+
+## 5. 插件状态与 HTTP API
+
+### 5.1 端点
+
+```
+GET    /api/plugins                  已加载插件清单 + 钩子 + UI + 错误
+POST   /api/plugins                  上传/替换（admin）{name, code}
+DELETE /api/plugins/{name}           删除（admin）
+GET    /api/plugins/{name}/state     读取插件自己发布的状态
+PUT    /api/plugins/{name}/state     替换状态（admin）
+```
+
+`GET .../state` 对**任意角色开放**：它是报表数据（开销、计数），用户自己的
+计费组件要能渲染。而 `PUT` 需要 admin。
+
+### 5.2 约定：`prices` 与 `state` 分离
+
+`PUT .../state` 的载荷里如果有 `prices` 键，它会被写进插件的 **`plugin.prices`**
+字段并从 `state` 里剔除。
+
+**为什么**：`state` 是累计量（历史），`prices` 是配置。一次改价如果整体替换
+`state`，累计量就没了——账目会在改价那一刻清零。分离之后：
+
+- 只带 `prices` → 改配置，**不动** `state`（累计量保留）
+- 带其它键 → 替换 `state`（这是显式的重置）
+
+> 插件可以不遵守这个约定，把整个载荷放进 `state` 自行处理。约定只为内置的
+> 计费插件存在。
+
+### 5.3 `GET /api/plugins` 的响应
+
+```json
+{
+  "plugins": [{
+    "name": "billing", "version": "1.0.0",
+    "description": "...", "author": "...",
+    "hooks": ["request_end"],
+    "ui": { "page": "billing", "elements": 1 },
+    "loaded": true
+  }],
+  "hook_errors": { "request_end": { "count": 3, "last_error": "billing: ..." } },
+  "plugin_dir": "/etc/llmsproxy/plugins"
+}
+```
+
+`hook_errors` 是**排错入口**：一个坏掉的插件表现为"功能缺失"而不是报错，
+这个计数让它可见。
+
+### 5.4 定时任务（`PLUGIN.schedule`）—— 浏览器关着也会跑
+
+要求插件做“随时间发生”的事（自动签到、token 轮换、额度轮询）时，声明一个
+调度表：
+
+```lua
+plugin.schedule = {
+  { fn = "refresh_token", every = 3600 },                 -- 每小时（秒）
+  { fn = "daily_checkin", every = 86400, at = "03:30" }, -- 每天固定时刻（本地时间）
+  { fn = "poll_quota",    every = 300, jitter = 30 },     -- 首次触发加 0-30s 抖动
+}
+function plugin.refresh_token()
+  -- 注意：直接写 plugin.state 就是对的 ——
+  -- 任务和钩子跑在同一个 VM 上
+  plugin.state.token = fetch_new_token()
+end
+```
+
+| 字段 | 含义 |
+|---|---|
+| `fn` | 要调用的插件函数名（必须存在） |
+| `every` | 间隔秒数。与 `at` 二选一 |
+| `at` | 每天本地时间 `"HH:MM"`；设了它就忽略 `every` |
+| `jitter` | 首次触发额外随机延迟秒数（避免多实例整点齐射） |
+| `timeout` | 解析保留但目前**不生效**（见下） |
+
+要点：
+
+- **内核 ticker 驱动**，不是前端轮询：没有浏览器、没人登录也会执行。
+- **任务跑在插件自己的 VM 上**，与请求钩子共用 `plugin.state` —— 任务写的
+  token 对下一个请求立即可见，也会经同一套机制持久化到 `.<name>.state.json`。
+- 任务函数出错只记 `hook_errors`，不影响钩子与转发。
+- 没有 `schedule` 的插件不获得任何额外 VM/goroutine（零开销）。
+- **超时不能中断一个运行中的 Lua 调用**（本 LuaJIT 构建的硬限制）。任务超过
+  10 分钟不返回，该插件被**停用**（`disarmed`）：不再调度，钩子快速失败并
+  记 `hook_errors`。这是为了不让一个卡死的任务把请求永久堵在它那把锁后面。
+  修好插件后重新加载（重传/重启）即可恢复。
+
+> 同一条 6.1 的约束：任务占着插件锁，所以**任务里不要写死循环**。
+
+### 5.5 自定义对外挂载点
+
+插件的 HTTP 端点默认挂在 `/api/plugins/http/...` 下。同一个声明**同时**可在两个
+公开命名空间下访问，只要把 `path` 的第一段起成插件名：
+
+```lua
+plugin.http = {
+  { path = "myplugin/callback", method = "POST", handler = "on_callback" },
+}
+```
+
+该端点因此可在三个地方访问：
+
+| 路径 | 用途 |
+|---|---|
+| `/api/plugins/http/myplugin/callback` | 默认前缀（带登录态的管理 UI） |
+| `/plugins/myplugin/callback` | 公开（浏览器路径） |
+| `/v1/plugins/myplugin/callback` | 公开（API 路径） |
+
+可占用的命名空间只有后两个：
+
+| 前缀 | 例子 |
+|---|---|
+| `/plugins/` | `/plugins/myplugin/callback` |
+| `/v1/plugins/` | `/v1/plugins/myplugin/callback` |
+
+限制（都是为了不把内核路由变成可被插件改写的）：
+
+- **不能影子内核路由**：与 `/v1/chat/completions`、`/v1/messages`、`/api/...`
+  等重叠的挂载在加载时就被拒绝，错误信息点名冲突对象。
+- **只能是上面两个命名空间**，不接受任意前缀（否则可以拦截推理请求）。
+- 鉴权沿用端点的 `roles` / `keys` / `public` 语义（见 §5.1）；
+  `/v1/plugins/...` 属于 API 路径，未认证返回 401；`/plugins/...` 为浏览器
+  路径，未认证会跳登录页。
+- 未声明的路径不会因为落在允许命名空间而被放行——不在 handler 表里就是 404。
+
+### 5.6 前缀代理：把插件自起的服务挂到网关同端口
+
+前节的自定义挂载点只能回答**由插件计算出来的内容**（`{status, headers, body/json}`）。
+若插件自己起了一个 TCP/HTTP 服务（典型：服务端浏览器栈 + noVNC），客户端就需要
+**字节级转发**，包括 **WebSocket 升级** —— 前者做不到。
+
+为此声明 `prefix = true`，handler 每次请求返回一个**回环目标**：
+
+```lua
+plugin.http = {
+  { path = "myplugin/proxy/:session", method = "GET", prefix = true,
+    roles = { "admin" }, handler = "proxy" },
+}
+
+function plugin.proxy(req)
+  -- 每次请求都问一遍：会话没了/过期了就返回 404，地址自然失效
+  if not sessionAlive(req.params.session) then
+    return { status = 404, json = { error = "no such session" } }
+  end
+  return { proxy = "http://127.0.0.1:60100" }
+end
+```
+
+规则：
+
+- **只能返回 `{ proxy = <目标> }`**，没有 `status` / `body`。写了 `status` 会被忽略。
+- 目标必须是 **带显式端口的字面回环 IP**（`http://127.0.0.1:60100`）。
+  拒绝 `https://`、`localhost` 这类主机名、无端口、带 userinfo/path/query 的地址。
+  理由：主机名可能被 hosts / DNS / 代理环境改写；通用能力只接受确定性地址。
+- 路由匹配同前缀下的**所有子路径**，`:param` 仍照常捕获，`req.path` 是完整
+  请求路径，子路径由插件自己从 `req.path` 里切。
+- **鉴权先于代理**：`roles` / `keys` / `public` 语义与普通端点一致。
+- **不转发网关凭据**：`Authorization`、`Cookie`、`api_key` 都不会传给后端服务。
+- **拒绝跨站**：`Origin` 与网关自身 host 不一致返回 403。WebSocket 由浏览器
+  发起且自动带 Cookie，否则第三方网页可借管理员会话开隧道。
+- **撤销点唯一**：handler 不再返回目标（或返回 404）即失效，内核不缓存目标。
+
+客户端拿到的 URL 是**相对网关口**的绝对路径（如
+`/api/plugins/http/myplugin/proxy/<id>/vnc.html`），因此远程访问、HTTPS 入口、
+Cookie 鉴权都自然生效，无需暴露额外端口。
+
+### 5.7 在运行时安装/更新适配器（token 轮换）
+
+插件可以在运行时安装、改写**自己的**适配器 —— 这是"带自动轮换的认证"的实现
+方式：拿着新 token 重写适配器源码，后续请求自然使用新逻辑（内核重建该适配器
+的池）。**可直接在插件 `.lua` 里调用**：
+
+```lua
+-- 每小时的定时任务：轮换 token 并重写适配器
+function plugin.refresh_token()
+  local tok = fetch_new_token()          -- 插件自己的取 token 逻辑
+  local name, err = __llmsproxy_adapters.install(
+    "myauth",
+    'return { name = "myauth", endpoint = "/chat/completions",' ..
+    ' headers = { ["Authorization"] = "Bearer ' .. tok .. '" } }'
+  )
+  if err then log("error", err) end
+end
+```
+
+| 调用 | 参数 | 返回 |
+|---|---|---|
+| `__llmsproxy_adapters.install(name, source)` | 适配器名 + Lua 源码 | `(生效名, nil)` 或 `(nil, err)` |
+| `__llmsproxy_adapters.update(name, source)` | 同上（只限自己装的） | `(true, nil)` 或 `(nil, err)` |
+| `__llmsproxy_adapters.remove(name)` | 适配器名（只限自己装的） | `(true, nil)` 或 `(nil, err)` |
+
+出错时不抛异常，而是返回 `(nil, err)`——与钩子/HTTP 处理器同一套约定，
+一个手滑的插件错误不会带走网关。
+
+安全规则（由 Go 侧强制，不是约定）：
+
+- 插件**只能改自己装的**适配器（归属表在 Go 侧记录，调用身份是插件启动时的
+  固定名字，无法冒充）。
+- 插件**不能影子内置适配器**（否则等于篡改发行物）；运维仍可自行覆盖。
+- 名字经过路径安全校验（无穿越/绝对路径/空白）。
+
+> 这条能力配合 §5.4 的定时任务，就是完整的自动轮换：**没有浏览器、没有人
+> 操作时，插件按时间自己把 token 换掉**。
+
+---
+
+## 6. 运行时约束（重要）
+
+### 6.1 一个插件 = 一个 Lua 状态（也就是一个 VM）
+
+适配器可以有多个独立的 worker 状态（它们无状态，这是对的）。**插件不行**：
+钩子通常往 `plugin.state` 里累加，多个状态就意味着总额被劈成几份，而写价格只
+写进其中一个状态，钩子恰好跑到另一个时**所有请求按 0 计费**。
+
+因此插件持有**唯一一个**状态，所有入口（`Fire` / `State` / `SetState` / **定时任务**）
+都用这同一把互斥锁串行化。
+
+注意： 这条约束对**定时任务尤其关键**：任务和钩子必须是同一个 VM，否则任务写的
+`plugin.state` 是一个请求路径永远读不到的副本 —— token 轮换看起来成功了，
+对实际流量完全无效。
+
+代价：**一个卡住的钩子会卡住该插件自己的钩子**（跨插件仍然并行，每插件各自
+一把锁、各自一个 VM）。所以——
+
+> **钩子与定时任务都必须短、同步、不阻塞。** 不要在钩子里做 HTTP 请求、睡眠
+> 或重计算；长耗时的周期工作应放进 `PLUGIN.schedule`（见 §5.4），它在自己的
+> 调度 goroutine 上跑，但仍然持有这把锁，因此不能是死循环。
+
+### 6.2 异常被隔离
+
+钩子里 `error()` 不会影响转发：异常被捕获、记进 `hook_errors`、跳到下一个插件。
+适配器变换出错会让源进入冷却，但插件出错**不产生任何惩罚**——插件是可选功能。
+
+### 6.3 内置可用函数
+
+与适配器相同：`json.encode` / `json.decode`、`log(level, msg)`、
+`hmac_sha256_hex` / `sha256_hex` / `base64_encode` / `tohex`。
+
+注意： `os.date` 在极简运行时里可能不可用（计费插件因此有降级路径）。
+
+### 6.4 命名
+
+- 全局 `__llmsproxy_plugin` 存放插件返回的 table，**不要占用**
+- 插件间状态完全隔离，一个插件改不了另一个的全局
+
+---
+
+## 7. 内置计费插件
+
+`plugins/billing.lua`，默认随首启 seed 进来，开箱可用。
+
+### 7.1 计费维度
+
+| 维度 | 用途 | 优先级 |
+|---|---|---|
+| `sources` | 源的固定价（如按请求计费的转发服务） | 中 |
+| `models` | 模型的 per-token 价 | 高 |
+| `keys` | 单个网关 key 的覆盖价 | **最高** |
+
+**token 价**优先级：`keys` > `models` > `default`。
+**`per_request` 固定价是叠加的**（不覆盖），所以一个生图模型可以既算 token 又收固定费。
+**`cache_discount`** 见 §7.7。
+
+### 7.2 价格单位
+
+**USD / 单个 token**。这是各家 provider 的公布口径，所以典型数值长这样：
+`1.25e-6`。插件内部乘以 token 数，全程不做单位换算。
+
+```json
+{
+  "prices": {
+    "currency": "USD",
+    "default":  { "prompt": 0, "completion": 0, "per_request": 0 },
+    "sources":  { "trae": { "per_request": 0.01 } },
+    "models":   {
+      "gpt-5.4": { "prompt": 1.25e-6, "completion": 1e-5 },
+      "kolors":  { "per_request": 0.04 }
+    },
+    "keys":     { "***a1b2c3": { "prompt": 1.1e-6, "completion": 9e-6 } }
+  }
+}
+```
+
+配置价目：
+
+```bash
+curl -X PUT http://127.0.0.1:8080/api/plugins/billing/state \
+  -H "Authorization: Bearer $ADMIN_KEY" -H "Content-Type: application/json" \
+  -d '{"prices":{"models":{"gpt-5.4":{"prompt":1.25e-6,"completion":1e-5}}}}'
+```
+
+读回账目：
+
+```bash
+curl -H "Authorization: Bearer $ADMIN_KEY" \
+  http://127.0.0.1:8080/api/plugins/billing/state
+```
+
+### 7.3 累计维度
+
+`total` / `by_source` / `by_model` / `by_key` / `by_day`（`YYYY-MM-DD` UTC），
+每项含 `cost`、`requests`、`prompt_tokens`、`completion_tokens`、`failures`。
+
+另有两个**降级观测**维度（来自 `chain_step`）：
+
+| 字段 | 含义 |
+|---|---|
+| `degraded_reqs` | 发生过降级的请求数 |
+| `by_tier_served` | 各档实际接单数（`{"1": 812, "2": 37}`） |
+| `skip_reasons` | 跳过原因计数，等待时长已归一（`no free slot within <wait>`） |
+
+这三项是"网关是不是在悄悄降级"的核心指标：一个持续降级的网关，账单结构和健康
+网关看起来一模一样——**除非**单独统计降级次数。
+
+### 7.4 计费策略：失败的请求怎么算
+
+**保留 token 费用，丢弃固定费用。** 理由：上游在生成后才 500，token 确实被消耗
+了；但那个从未真正发生的固定费不该收。
+
+这是本插件里**最可争议的一条**。想改成"失败也收固定费"：
+
+```json
+{ "prices": { ... }, "count_failures": true }
+```
+
+### 7.5 注意： 计费插件只报表，不执法
+
+**网关自己的配额会计（`internal/gateway/stats.go`，入口处强制）才是限额权威。**
+本插件不参与任何路由或配额决策。
+
+理由：两套独立的会计路径如果对不上，比一套功能略少的更糟。计费是**观察**，
+配额是**控制**，二者分开。
+
+### 7.6 未定价流量（重要）
+
+**任何维度都没配价的请求，成本记 0。** 这是最危险的失败模式：账单照样能加总，
+只是**悄悄少报**，而且没有任何报错。
+
+所以插件单独统计它们：
+
+| 字段 | 含义 |
+|---|---|
+| `unpriced_reqs` | 没有任何价目覆盖的请求数 |
+| `unpriced_models` | 按模型点名（`{"MYSTERY-MODEL": 12}`）——直接告诉你价目表缺了哪一行 |
+
+仪表盘上有 "Unpriced" 卡片。**这个数应该是 0**；不是 0 就去补价目。
+
+注意"未定价"不等于"免费"：这些请求的 `requests` / token 数**照常计入**
+`total` 与各维度，只有金额是 0。
+
+### 7.7 提示缓存计价
+
+**缓存命中的 prompt token 不按全价算。** 绝大多数 provider 对缓存读给很深的折扣
+（常见是 1/10），而 agent 流量会反复重放长前缀——正是缓存要让它便宜的那类流量。
+
+```
+fresh  = prompt_tokens - cache_hit_tokens   → 全价
+cached = cache_hit_tokens                   → 全价 × cache_discount
+```
+
+`cache_discount` 默认 **0.1**（10 倍折扣），因为 DeepSeek / Qwen / Kimi 等都是这个
+量级。它是**每个 provider 的事实、不是自然常数**，所以可以按条目覆盖：
+
+```json
+"models": { "gpt-5.4": { "prompt": 1.25e-6, "completion": 1e-5, "cache_discount": 0.25 } }
+```
+
+设成 `1` 恢复成旧的"prompt 一律全价"行为，设成 `0` 表示该 provider 不打折。
+
+优先级与 token 价一致（`keys` > `models` > `default`）。
+
+> **这一条改过行为。** 修复前缓存命中按全价算：100 万 prompt token 里 90 万是
+> 缓存命中，会算出 10 USD 而不是 ~1.9——**高估约 10 倍**，而且恰好发生在缓存
+> 最有价值的高频流量上。
+
+### 7.8 数据从哪来
+
+`request_end` 的 `prompt_tokens` / `completion_tokens` 优先取上游真实的
+`usage`；上游没报时网关用字节估算（`len/3+1`）。流式请求在流结束后用上游真实
+数字**覆盖**估算值。所以计费数字的精度取决于上游是否报 usage。
+
+---
+
+## 8. 排错
+
+| 现象 | 查什么 |
+|---|---|
+| 插件没出现在 `/api/plugins` | 目录对不对（响应里的 `plugin_dir`）；文件是不是 `.lua` |
+| `loaded: false` 且有 `error` | 语法错误或没 `return table`，错误信息在 `error` 字段 |
+| 功能"没反应"但无报错 | 查 `hook_errors`——坏钩子只记录不抛出 |
+| 钩子没被调用 | 该 stage 确实触发了吗（`routed` 只在**成功**选源后触发，调度全失败时不触发） |
+| 界面空白 | 内核的 `GET /api/ui-inject` 里有没有你的 `page_id`；脚本有没有报错（浏览器 console） |
+| `pluginAPI` 未定义 | 脚本在注入前执行了；确认用的是 `mount` 而不是别的方式插入 |
+
+### 调试钩子
+
+插件的 `log(level, msg)` 输出到网关的日志：
+
+```
+journalctl -u llmsproxy -f | grep -i plugin
+```
+
+---
+
+## 9. 与适配器的区别
+
+| | 适配器 | 插件 |
+|---|---|---|
+| 位置 | `adapter_dir` | `plugin_dir` |
+| 作用 | 上游协议转换 | 请求流水线 + 界面 + 周期任务 |
+| 钩子 | `transform_request` / `transform_response` / `transform_stream_chunk` / `build_headers` / `transform_error` / `serialize_*` | `request_start` / `routed` / `request_end` |
