9114468753 fix: empty-array content becomes invalid {} on every pass-through adapter; gemini/ollama drop tool calls
Three related forwarding defects found by auditing every adapter with a
tool-calling replay (assistant turn with content:[] + tool_calls).

1) content:[] -> content:{} (all 12 openai-adapter sources, plus
   deepseek/trae/sensenova/agentrouter/github/groq/kimicode/mistral)

   Lua adapters json.decode the request and re-encode it, and an empty Lua
   table is indistinguishable from an empty JSON array — the encoder emits
   {} for both. Agent clients serialise a tool-calling assistant turn with
   no text as content:[], so every pass-through adapter rewrote it to
   content:{} — not valid OpenAI (content is string|array|null). Verified
   against a live upstream: content:[] produced "400 invalid arguments"
   while content:"" was accepted.

   Fixed once at the decode boundary (types.ChatMessage.UnmarshalJSON):
   empty-array content normalises to "" and an empty tool_calls array is
   dropped, so every adapter — including future ones — sees a valid shape.

2) gemini dropped tool_calls and never emitted functionCall /
   functionResponse; the tool role also stayed as an invalid role inside
   contents and system was not moved to systemInstruction.

3) ollama copied only role/content, dropping tool_calls and the call
   attribution entirely (it needs tool_name, not tool_call_id).

Test: TestAdaptersPreserveToolCalls asserts, for every adapter, that the
call id (or function name where the wire format has no id), the function
name, the tool result and the trailing user turn all survive, plus a
negative control for plain text.

611e975456 fix(gateway): 上下文超窗错误归一化,客户端才能压缩重试
问题:上游返回上下文超窗时,客户端(pi)既不压缩也不重试,只看到一条
普通上游错误。链路两处叠加:

1. 措辞不在客户端识别列表里。pi 靠 @earendil-works/pi-ai 的
   OVERFLOW_PATTERNS(25 条正则)判断超窗,而 justworker 返回的是
   「请精简对话历史…(Context window is full…)」——与那 25 条一条都不匹配
   (最接近的 /context window exceeds limit/i 也不命中,因为措辞是 "is full"
   而非 "exceeds limit")。
2. AUTO 链路的每条 tier 错误按 80 字节 OneLine 截断,而 "Context window
   is full" 这类短诊断词常出现在尾部,正好被按字节切掉(直连路径是 160
   才保住)。

修法:
- 新增 overflowMarkers 识别超窗措辞(含中文写法),命中时把客户端可见
  错误归一化为 context_length_exceeded 前缀——它命中 pi 的
  /context[_ ]length[_ ]exceeded/i,超窗因此可被发现并触发压缩重试。
- AUTO 链路每条 tier 错误宽度 80→160,短诊断词不再被截断。

归一化只加前缀,原始诊断信息保留,便于定位是哪一层超窗。

测试:internal/gateway/overflow_err_test.go(5 例,含「标记必须命中 pi
正则」、非超窗不得误标、80 vs 160 宽度的回归对比)。

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).

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.

#### 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**。

- Clients authenticate with any authorized key's plaintext as
`Authorization: Bearer <key>`.
- Deleting a key removes it from the store immediately.
#### 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**.

# 插件系统(Plugin System)
> **English**: this document is the reference for writing ModelRouter plugins.
> The Chinese version is the primary one; section titles map 1:1.
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。
```
客户端请求
│
┌─────────▼──────────┐
│ request_start │ 已解析、已鉴权,尚未选源
│ · type │ "chat" | "stream" | "image"
│ · model │ 客户端请求的原始 model("AUTO" 也在这里)

│ · error │ 失败原因,成功时为 ""
│ · time │ unix **毫秒**
└─────────┬──────────┘
│
写审计 + 聚合统计
```
### 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。
---
## 6. 运行时约束(重要)
### 6.1 一个插件 = 一个 Lua 状态
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`)用互斥锁
串行化。代价:**一个卡住的钩子会卡住所有插件的钩子**。所以——
> **钩子必须短、同步、不阻塞。** 不要在里面做 HTTP 请求、睡眠或重计算。
### 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`。
⚠️ `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 ⚠️ 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

### 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 |
| 钩子 | `transform_request` / `transform_response` / `transform_stream_chunk` / `build_headers` / `transform_error` | `request_start` / `routed` / `request_end` |
| 状态 | 每个源独立,多 worker | 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 |
| 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)。

// Agent-facing management API.
//
// The Web UI has always driven the gateway through /api/*, so the management
// surface already exists. What it lacked was anything an agent could *rely* on:
// no way to discover the contract, no single call that answers "what is the
// current state", and per-endpoint response shapes that make scripting brittle.
//
// This file adds a versioned, self-describing facade under /api/v1 without
// touching the existing endpoints, so the Web UI keeps working unchanged while
// agents get a stable contract:
//
// GET /api/v1 — machine-readable index of every endpoint
// GET /api/v1/overview — one call: sources + auto chain + keys + health
// GET /api/v1/sources — sources, credentials masked
// GET /api/v1/sources/{name} — one source
// GET /api/v1/auto — scheduling chain + live slot states
// GET /api/v1/keys — key metadata (never the secret)
// GET /api/v1/models — every model id the gateway can route
// GET /api/v1/health — per-source health, no auth needed beyond the key
//
// Auth is the same gateway key as everywhere else (Authorization: Bearer, or
// ?api_key=, or the gw_key cookie). Read endpoints accept any role; writes
// still require admin, enforced by the same middleware the UI goes through.

// This file covers the second round of the same class of defect bf0657b fixed.
//
// bf0657b stopped a partial source edit from clobbering api_key. The upsert
// still rewrites the WHOLE source, so every other field the request could not
// express was reset to its zero value on any edit: proxy_url, api_key_env,
// timeout and queue_timeout.
//
// The four are worse than cosmetic because they change how the source dials out.
// proxy_url silently turns a proxied upstream into a direct one (or vice versa)
// and api_key_env turns a source whose credential lives in an environment
// variable into a credential-less source — which keeps answering 200 on write
// and only fails on the NEXT call upstream, long after the editor left.
//
// The trigger is not exotic scripting: the WebUI's own edit form posts exactly
// such a payload. See TestWebUIEditPayloadPreservesRoutingFields.

// fields, then boots a gateway over it.

// did not carry api_key persisted an empty/placeholder credential. The
// source kept its name and models and answered 401 on the next call, well

// Measured before this change: one Fire() call cost 14.6us, of which
// json.Marshal(payload) was 4.0us and json.Unmarshal back into interface{} was
// 5.6us — 67% of the whole hook, spent re-deriving a tree that the very next
// line (pushGoValue) already knows how to walk natively.
//
// The round-trip existed because payload arrives as map[string]interface{} and
// pushGoValue wanted a plain interface{} tree. pushGoValue already handles
// map[string]interface{} and []interface{} directly, so the fix is a converter
// that flattens the concrete Go types the gateway actually produces, instead of
// a generic serialize/parse.
//
// The JSON path is kept as the fallback for types the fast path does not know,
// so a plugin payload carrying something exotic still arrives rather than being
// silently dropped.
// jsonNumberType is the type json.Unmarshal produces for every JSON number.
// The fast path recognizes it so numbers survive as numbers rather than being
// stringified into a different Lua type.
type jsonNumberType = float64
// fastToPlain converts the concrete Go values the gateway puts in a hook

// - json.Number-ish types (all float64 in practice)
// - int / int64 / uint variants, which must land as Lua numbers, not as the

// - []string and map[string]string, extremely common in payloads and NOT
