chore(version): 1.5.2

fix(opencode): never drop an assistant turn that carries tool_calls
An agent client (pi) serialises an assistant turn whose content is only [thinking, toolCall] as content:[] with tool_calls. The multimodal-strip pass treated an empty content array as 'nothing left, drop the whole message' and discarded the tool_calls with it. The next message is that call's tool result, so it arrived orphaned: the model saw a result for a call it had never made and re-issued the same call on every turn — an endless repeated-tool-call loop. Reproduced against a capture sink: content:[] lost tool_calls, while content:"" and content:null kept them. Only messages with neither usable content NOR a tool call now get dropped. Content that collapses to empty but still has tool_calls or a tool_call_id is emitted as "" instead. Test: TestOpenCodeKeepsToolCallWithEmptyContent (plus a negative control that an image-only message without tool calls is still dropped).

-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
-{"error":{"type":"rate_limit_exceeded","message":"token quota exceeded for \"deepseek-v4-flash\" (5000000/5000000)"}}

-#### Per-key usage quota
-
-**Quotas are per model.** Each key's `models[]` list gives every model its own
-token budget and request budget. One model running out affects only that model
-— the key's other models keep working.
-
-```yaml
-keys:
-  - key: sk-gw-<hex>
-    role: user
-    name: agent-alice
-    models:
-      - model: deepseek-v4-flash
-        token_quota: 1000000   # this key's token budget for this model
-        req_quota: 20000       # requests within the window
-        period: nhour          # "" | hour | week | month | nhour
-        hours: 6               # n-hour only
-      - model: AUTO
-        token_quota: 5000000   # AUTO is a quota entry like any other
-        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`**
-  (`rate_limit_exceeded`) and the message names the model that ran out, so a
-  client resumes when the window rolls over; a model the key may not use stays
-  403. **Admin keys are never capped** (quotas on their scopes are not
-  enforced either), so a cap can never lock the operator out.
- Buckets are whole unix hours, so a window frees up at most an hour late
-  (deliberately freeing late rather than overspending).
- `PUT /api/keys/{key}` submits quotas by submitting `models` — the caps are
-  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**.

-# channels 插件与参考插件的三线对齐表
-
-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 |
-|---|---|---|---|
-| trae | OAuth 17 参数 + 设备身份派生 | callback | ✅ 逐字节对齐（含 login_trace_id / machine_id / x_device_*） |

-| cline | device-poll | device-poll | ✅ |

-| gemini | OAuth + client_secret | callback | ✅（含 client_secret、localhost 主机、6 scope） |
-| lobsterai | 本地回调 + authCode 换 token | callback | ✅（含动态版本号、3 步活动领取） |
-| opencode | paste | paste | ✅（参考本身即粘贴凭据） |

-| zcode | init-poll | init-poll | ✅ |
-| loomy | 微信扫码 poll | wechat-poll | ✅ |
-| 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"**。
-
-## 判据清单
-
-| 文件 | 锁死什么 |
-|---|---|
-| `internal/lua/plugin_adapter_capability_test.go` | 三条能力（凭据/流式状态/加密原语） |
-| `internal/lua/adapter_prelude_test.go` | 前导注入 + 语义值正确 + 旧适配器行为不变 |

-# 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。

-
-穷尽对照参考仓 **143 个 .ts 模块 / 77,720 行**。约定：
-✅ 已对齐 · ⚠️ 部分/简化 · ❌ 未实现 · ⛔ 明确不做
-
-## 本轮（第 2 批）新补的
-
-| 模块 | 参考规模 | 补了什么 / 为什么 |
-|---|---|---|
-| `dead-model-store` | 708 | 上游下架的模型仍显示且标"免费"，一点就 404。**判据只用阳性 404 证据，绝不拿远端目录反推**（buddy 那类平台目录残缺，反推会删可用模型） |
-| `remote-catalog-gate` | 114 | 参考点名"不能省"：目录拉不到会放大成「一次请求 × 每个模型」，首屏卡死 |
-| `buddy-balance-rank` + `loomy-balance-rank` + 两个 selector | ~1000 | **余额分档选号**：优先用「15 天内到期」的号，否则积分白白作废；锁定时只剩永久的号等同不可用 |
-| `account-probe` | 568 | `account_test` **此前一个网络请求都不发**（恒返回 ok:true/ms:1）—— 假阳性 |
-| `model-gate` | 218 | 源改**串行 + 按模型节流**（并发发起必然浪费一个配额；串行不保证间隔） |
-| `ttl-cache` / `serial-queue` | 291 | 抽成通用件，消掉三处各自手写的缓存/冷却逻辑 |
-| `opencode-capability` | 423 | isFree 改由 models.dev 的 `cost` 权威决定（不再是硬编码快照）。**受内核 4 MiB 上限约束不可用**，已如实降级为可选增强 |
-
-另修 3 个**静默失败**：`account_test` 不发请求、业务级错误（HTTP 200 + body 带
-error）被当成功、`pcall` 只取 ok 不看返回值（把诊断信息扔了）。
-
-## 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" |
-| `qoder-wasm` + `qoder-envelope` | 932 | **wasm 二进制不在仓库**（`find -name '*.wasm'` 为空，属构建产物）。拿不到就无法实现 |
-| `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** |
-| `reasoning-ladder` | 182 | 需要内核支持 `efforts` 字段（`Model` 结构只有 id/priority/kind/meta）。属内核改动，按纪律不做 |
-| `badge-*` / `image-budget` / `ttl-cache`(已补) | ~500 | 徽标订阅、图片预算 —— 宿主 UI 特性 |
-| `raccoon-login-page` / `raccoon-qr` | 1124 | 登录页与二维码的完整实现（我们走简化版） |
-| `zcode-carrier-page` | 93 | 内部载体页（依赖 DSH Desktop 的 webview guest，我们没有那个壳） |
-| `cline-*` 4 个 / `gemini-project` / `gemini-sigstore` / `loomy-sign`(部分) | ~900 | 平台细节与签名持久化 |
-
-## 一句话结论
-
-**平台登录/凭据/源注册这条主线已打通且逐平台对齐**（12 平台零 manual、三平台
-自装适配器、SOLO/信封/AK-SK 签名逐字节验证）。
-**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
-（captcha 系 ~3300 行）；(2) **二进制缺失**（qoder wasm）。
-其余是宿主 UI 特性或前提不存在的模块。

-# 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

 返回非 table 会报错；返回 `{}` 表示无自定义头（不会回退静态头）。

-### 出向序列化钩子（契约 v2）
-
-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 "" } },
-    stop_reason = payload.finish_reason == "stop" and "end_turn" or nil,
-    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。
-
-规则：
-
- 只有声明了该端点且实现了 `deserialize_request` 的适配器会让内核让出。
- 没有适配器认领时，内核内置解析接管（未配置的部署仍能工作）。
- 认领了但钩子**执行失败**是硬错误（400），不会静默回落到另一种协议解析——
-  客户端说的正是这个适配器声称支持的协议，悄悄换解析器只会错误调度请求。

-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
-

-  "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 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` |
-| 周期任务 | **无**（无状态请求级） | `PLUGIN.schedule`（内核 ticker 驱动） |
-| 对外端点 | 不开放（见 §5.5） | `/api/plugins/http/...` + 自定义挂载 |
-| 状态 | 每个源独立，多 worker | **单 VM、单状态**，见 §6.1 |
-| 出错后果 | 该 (源,模型) 进入冷却退避 | 仅该功能缺失；卡死则停用该插件 |
-| 鉴权 | 需要 `gateway_keys` 之外的独立凭据 | 网关 key |
-| 必需性 | 核心 | 可选，缺了网关照常跑 |
-
-完整适配器协议见 [lua-adapters.md](lua-adapters.md)。

-// The hard part is not the GET /models call — it is guessing which URL the

-// base_url + adapter endpoint (openai contributes "/chat/completions"), so a
-// base_url that already ends in "/v1" yields "/v1/chat/completions" while a
-// base_url of "/v1" plus our default image path yields the broken
-// "/v1/v1/images/generations". Vendors disagree on whether the version segment
-// belongs to the base or to the path, and there is no header that says which.
-//
-// So discovery does not trust the URL it is given. It tries a small, ordered
-// set of candidates, records which one answered, and reports that back as the
-// normalized base_url + adapter endpoint pair. A caller who typed the wrong
-// form gets a working source anyway, plus the correction needed to make it
-// permanent.
-//
-// What is deliberately NOT here:
-//
-//   - No guessing of model capabilities from the name. "vision" in an id does
-//     not make a model accept images, and marking an image-only endpoint as
-//     kind:"chat" makes every AUTO request fail on it. Kind stays "chat" unless
-//     the upstream's own metadata says otherwise (see discoveredModelKind).
-//   - No live probe per model. A single-token completion per model would cost
-//     real money across a 34-model catalog and takes minutes. /models is the
-//     cheap, authoritative-enough signal for "this id is served here"; whether
-//     it actually answers stays for the normal request path to discover.

JianFeeeee	499f0cac2f	fix(opencode): never drop an assistant turn that carries tool_calls An agent client (pi) serialises an assistant turn whose content is only [thinking, toolCall] as content:[] with tool_calls. The multimodal-strip pass treated an empty content array as 'nothing left, drop the whole message' and discarded the tool_calls with it. The next message is that call's tool result, so it arrived orphaned: the model saw a result for a call it had never made and re-issued the same call on every turn — an endless repeated-tool-call loop. Reproduced against a capture sink: content:[] lost tool_calls, while content:"" and content:null kept them. Only messages with neither usable content NOR a tool call now get dropped. Content that collapses to empty but still has tool_calls or a tool_call_id is emitted as "" instead. Test: TestOpenCodeKeepsToolCallWithEmptyContent (plus a negative control that an image-only message without tool calls is still dropped).	2026-09-10 19:32:47 +08:00
JianFeeeee	7fb8f96b82	fix(gateway): AUTO scope grants all models — restrict to routing mode only A key with scope=[AUTO] could previously: 1. request ANY concrete model id directly (hasScopeModel/checkModelScope treated AUTO as a wildcard) 2. see the full 56-model list on /v1/models (intersectModels considered AUTO as grant-everything) AUTO now only authorizes the AUTO routing mode. Direct requests to a specific model require an explicit scope entry. Also carries agentrouter.lua WAF fingerprint headers (Origin/Referer/ X-Requested-With) already staged on this branch. Tests: TestHasScopeModelWithSourcePrefix updated; full suite green.	2026-09-10 12:51:40 +08:00
