0938a45ced fix(ui): per-key 弹窗复用共享弹窗ID、编辑即落盘、空画布显示226个模型
截图看渲染 + 交互实测后发现的四个问题,都出在我自己新写的代码里。

一、弹窗用了全站共享的 #modal-wrap。
这个 id 是 App 内所有弹窗共用的,且允许多个同时存在("添加档位"选择器就
开在本弹窗之上)。既有代码靠 .closest() 或 closeTopModal() 从按钮往上找,
是有效的——但本弹窗还要从画布侧被查(sortCanvasEl / keyAutoClose /
keyAutoInherit),那里没有按钮可走。实测点"添加档位"后 DOM 里同时有
modal-wrap=1 和 key-auto-modal=1,getElementById 会命中文档里的第一个,
也就是用户没在看的那一个:取消关掉错误的框,画布也可能解析到选择器上。
改为独立 id #key-auto-modal。

二、编辑即落盘,保存/取消形同虚设。
scrAddFromForm / sortScopeSave / scrDelSlot 等 6 处编辑后立刻调
persistAuto()。全局页这样是有意的(改动立即生效),但它和自己页面上那句
"点击保存排序后生效"的提示自相矛盾;在 per-key 弹窗里更严重——加一个槽位
就已经写进那个用户的链了,取消也无法撤销。收敛到 afterChainEdit():
有 scope 时只提示、不落盘,保存是唯一写入口。

三、无独立链时画布显示全部 226 个模型。
注释写的是"显示空画布",实现却是 buildLanes(idx, [], 'chat')——空 rules
会走 discovery 兜底,把每个源的模型全填进去。用户打开弹窗看到 226 个色块,
会以为这些就是这个密钥的链。改为空 rules 直接给 []。

四、"使用全局链"提示不随画布变化。
加完槽位后仍显示"该密钥使用全局 AUTO 链",与旁边的色块直接矛盾。改为由
afterChainEdit 触发、按画布是否有内容决定去留。

另:批量替换时正则的缩进假设错了一次,把 afterChainEdit 自己改成了自调用
(无限递归),node --check 抓到后修掉。这类批量替换必须先过语法检查。

判据两条 + 变异:弹窗回到共享 id → 判红;去掉 scope 分支 → 判红。
CDP 实测:弹窗 id 唯一、添加后画布 0→1 块、添加后服务端 inherits=true
(未落盘)、取消后仍 inherits=true、选择器与弹窗并存互不干扰。

57abc25bb9 fix(stats): 日/周/月视图请求记录表空白,滚动加载顺序错乱
首页记录表由 paintRecords(st.records) 渲染,而 /api/stats 的 period 分支
手写了一份响应 map,压根没有 records 字段 —— 只有 all 分支走 Snapshot()
才带得上。实测切到日/周/月,记录表恒为空。

两处数据源也不一致:

| 端点 | 数据源 | 排序 |
|---|---|---|
| /api/stats(all)| 内存ring(几百条)| oldest-first |
| /api/stats/records(翻页)| 审计文件(全部)| newest-first |
| /api/stats(period)| 无 | 无 |

前端靠 paintRecords 里一句 .reverse() 把 all 的 oldest-first 转成 newest-first,
翻页端点则本来就是 newest-first。首屏和翻页方向相反,滚动时新旧行会错位
拼接;且 all 分支不带 next_cursor,表永远停在第一屏。

修法:两个分支都改用 AuditPage(与翻页端点同一份代码路径),记录方向统一
由它决定,前端去掉 .reverse()。附带好处:记录深度不再受 maxRecs 限制,
"全部"视图真的能翻到底。

判据三条,变异验证:period 分支返回 nil records → 前两条判红;all 分支不
覆盖 records → "no next_cursor"判红。变异过程中我自己也犯了两次错:第一版
判据硬编码 newest-first,而AuditPage 在单文件(整块读完)与多文件(分块反向
读)下方向不同,改为断言两处方向一致;第三版想测 admin 过滤,但
newTestGateway 的 sk-test 不是 admin,改为测真正的越权边界(非admin 不能
用 ?key= 看别人的记录)。

CDP 实测:四个视图各 100 行、时间从新到旧,滚动加载 100→200 行且新末行
时间更旧(顺序衔接正确)。

95ac9db67a fix(ui): per-key 编辑器画布画错容器、保存成功却不关弹窗
CDP 实测发现两个真 bug,都是复用画布时引入的。

一、画布画进了后台标签页。sortCanvasEl() 原本按文档顺序找,先命中
#scr-canvas(全局优先级页的画布)。而弹窗是挂在设置页之上的,两个画布
同时存在于 DOM —— 于是 per-key 的 36 条泳道被画进隐藏的全局画布,弹窗
里空空如也,回���全局页还会发现自己的链被覆盖了。

改为按 sortState.scope 解析:有 scope 就用 #key-auto-canvas,否则用
#scr-canvas。

二、保存成功却弹窗不关。!j.slots 分支里我写了 return,跳过了
keyAutoClose。写确实成功了(服务端已存),但用户看到弹窗还开着、按钮
还是禁用状态,会反复点保存。而且那条 toast 文案写成"保存后 AUTO 请求
会失败",读起来像保存失败了 —— 一并改成"已保存,但槽位无法解析…"。

判据两条,变异验证:恢复按文档顺序查找 → 第一条判红;!slots 分支加
return → 第二条判红。第二条最初只查 keyAutoClose() 是否存在,变异加了
return 仍然通过,属于判据漏放,已改为扫描 try 块内 close 调用之前的
所有 return 语句。

CDP 复测(先开全局页制造干扰,再开 per-key 弹窗):
- 弹窗画布 36 泳道,全局画布保持 4 泳道未被污染
- 保存 gpt-5.2@xinjianya 后弹窗关闭、服务端存储正确、scope 清空
- 重开弹窗读回 [["gpt-5.2@xinjianya"]]

### 自动探测模型列表
不想手抄模型 id 时,只填 URL 和 key,让网关去扫:
```bash
# 只探测,不写任何东西
curl -X POST http://127.0.0.1:8080/api/sources/discover \
-H "Authorization: Bearer sk-gw-…" -H "Content-Type: application/json" \
-d '{"base_url":"https://api.vendor.com/v1","api_key":"sk-…"}'
# → {"ok":true,"base_url":"…","endpoint":"","models":["gpt-x",…],
# "image_models":["gpt-image-2"],"models_path":"/models","latency_ms":1387,…}
# 探测后直接落库
curl -X POST http://127.0.0.1:8080/api/sources/discover/apply \
-H "Authorization: Bearer sk-gw-…" -H "Content-Type: application/json" \
-d '{"base_url":"https://api.vendor.com/v1","api_key":"sk-…","name":"vendor"}'
```
WebUI 源编辑框里也有「自动探测模型」按钮:填好 URL 和 key 点一下,列表自动
填好,仍需点保存才生效。
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
探测顺手抹掉为 AUTO 链手工调过的 priority,是最难排查的一类数据丢失。
- **`api_key` 留空表示沿用已存值**,不会把凭据清空。
`config.yaml`、`runtime.json`、`master.key`、`adapters/` 均不提交版本库(见
`.gitignore`),请随备份带走——`master.key` 丢失后运行时密文无法解密。

// Model discovery: turn "here is a URL and a key" into a configured source.
//
// The hard part is not the GET /models call — it is guessing which URL the
// upstream actually serves. This gateway builds request paths as
// 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.

// treats "[no tests to run]" as a hard error rather than a green run.
//
// It also must not be run against a DIRTY tree: the mutant is written over
// discover.go, and a leftover mutant from a killed run would make the baseline
// green against broken code while every verdict came from the wrong source.

-- tokenplan / discovery-api (intern-ai.org.cn) — OpenAI-compatible with two
-- differences that a stock OpenAI adapter gets wrong.
--
-- 1. REASONING IS A SEPARATE FIELD, AND IT IS MOST OF THE OUTPUT.
-- Every response carries `reasoning_content` (non-stream) or
-- `delta.reasoning_content` (stream), disjoint from `content`. Measured on
-- qwen3.8-27b: a one-sentence answer cost completion=303 tokens of which
-- reasoning=295 — 97% of the budget went to thinking. A caller handing the
-- upstream's `content` straight through sees an empty string and concludes
-- the model is broken, when in fact the answer was cut off by max_tokens
-- before any of it became text.
--
-- So the reasoning is passed through as its own field rather than folded
-- into content. Folding would be worse than dropping it: the page would
-- render the model's private deliberation as its reply.
--
-- 2. `finish_reason: "length"` WITH `content: null` IS NORMAL HERE, NOT AN ERROR.
-- A reasoning model that exhausts its budget before emitting text produces
-- exactly `{"content": null, "reasoning_content": "...", "finish_reason":
-- "length"}`. The generic empty-response guard in the gateway reads a
-- content-less completion as "upstream returned nothing" and fails the
-- attempt — which is why this adapter does not try to be clever: it reports
-- both fields and the real finish_reason, and the caller decides.
--
-- 3. MODEL NAMES ARE REWRITTEN BY THE SERVER.
-- Requesting `qwen3.8-27b` answers with `model: "qwen3.8-27b-fp8"`. The
-- response's model field is the truth about who served the request, and the
-- gateway records it (billing keys on the SERVED model, not the requested
-- one). Nothing here normalises it back: rewriting it to the requested name
-- would make the audit trail lie about what actually ran.
--
-- Also worth knowing when configuring this source: remote image URLs are
-- fetched BY THE UPSTREAM and time out reliably (`media_fetch_failed`). Images
-- must be sent inline as data: URLs. Measured: base64 worked, a Wikimedia URL
-- did not.

// The declarative decoder.
//
// Why this exists: plugin declarations were read by three hand-written functions
// (readPluginUI, readPluginExports, readPluginHTTP) that each re-implemented the
// same walk over a decoded Lua table — get this field, coerce it, append it. The
// field names lived in the .lua and again in the Go, so adding one meant editing
// both, and forgetting the Go half produced NO ERROR AT ALL: the field silently
// read as unset.
//
// That happened four times in one session, all the same shape — a declaration
// field silently reading as unset:
//
// - readPluginUI and readPluginExports each re-walked the Lua stack per field
// and decoded through different helpers with different INDEX SEMANTICS.
// - readPluginHTTP read a Lua array with an index loop; golua's GetField does
// not convert a numeric string key, so the loop produced an empty list and
// every plugin appeared to declare no endpoints.
// - The endpoint-access override keys (plugin#path) leaked into the plugin
// audience listing, because both lived in one map and nothing distinguished
// them on the way out.
//
// On the first two: the comments that shipped with those fixes — in three places
// and in a commit message — claimed the cause was that registration runs before
// setupGlobals installs the json global. That was never verified and is FALSE.
// Measured: setupGlobals runs at vm.go:574, the readers at 787, json is present,
// and luaToJSON decodes the same stack shape correctly. The real constraint is
// that luaTableToGoValue resolves a negative index to absolute immediately
// (GetTop()+idx+1), so it is only valid while the caller's stack shape holds —
// which is why the decode now happens once, at the edge, and never per field.
//
// // A schema makes the failure loud instead: an unknown or mistyped field is a
// load-time error naming the field and the plugin, and the Go side has exactly
// one list of field names to keep in sync.
//
// The schema is deliberately data, not reflection or struct tags. A plugin author
// reads one table in this file to learn what the gateway understands; adding a
// declaration field is one line here plus one in the .lua, and a declaration the
// gateway ignores is reported rather than dropped.

// The original production bug was three readers using luaToJSON, which depends
// on the `json` global that setupGlobals installs AFTER plugin registration. A
// mutation that swaps luaTableToGoValue back to luaToJSON still PASSES here:
// these tests drive decodeUIExtension with an already-decoded Go map, so the
// decode edge — which is exactly where the bug lived — is not exercised.
//
// Making it catchable needs a test that loads a plugin through the real
// registration path with json deliberately absent, and asserts that a declared
// field survives. LoadSource in TestUnknownDeclarationFieldIsReported does go
// through that path, but its assertions are about the diagnostic path, not about
// whether the decode returned the values.
//
// Until that exists, treat "the decode uses luaTableToGoValue" as enforced by
// review and by this comment, not by a mutation.
// TestDecodeSurvivesWithoutTheJSONGlobal closes the gap recorded above.

// It loads a plugin through the REAL registration path and asserts the declared

package lua
// Outbound HTTP for plugins.
//
// The billing plugin never needed this: everything it reports arrives on a hook
// payload that the gateway produced while forwarding a request. A quota plugin
// is the first thing that must REACH OUT on its own — Command Code exposes
// /alpha/billing/credits and friends, and there is no way to learn a plan's
// remaining balance without asking.
//
// That capability is also the sharpest edge in the plugin model. A plugin is a
// single .lua file the WebUI installs from a textarea: untrusted, browser-facing
// code that runs in the gateway process. Handing it a general-purpose HTTP
// client would make every install a standing SSRF primitive against whatever
// the gateway can reach — the cloud metadata endpoint, the cluster control
// plane, whatever else sits on 127.0.0.1 in this deployment. Reading the
// environment for credentials is a second door out.
//
// So the bridge is deliberately narrow:
//
// - Destination must match a host that a CONFIGURED SOURCE already talks to.
// Those are operator-declared, not plugin-declared: a plugin cannot widen
// its own reach by inventing a URL, and an existing source's host is
// exactly the set of upstreams this deployment already trusts with API keys.
// - http:// on a non-loopback host is refused. Credentials belong in HTTPS.
// - Loopback needs no explicit opt-in: it is the only way a plugin can read
// the gateway's own API (the billing rules UI does exactly that), and it
// cannot leave the machine.
// - Every request is bounded by a timeout and the response is size-capped, so
// a plugin cannot wedge a worker goroutine or exhaust memory.
// - Credentials are NEVER read from the environment here. A plugin that needs
// a key must be given it (state, or the caller's own config), which keeps
// the grant visible to the operator instead of silently ambient.
//
// Redirects are NOT followed: the allowlist is checked per hop, and a redirect
// to an unlisted host would otherwise walk straight past it. A 3xx is returned
// as-is so the plugin can see it.

// Three properties have to hold, and none of them is visible from the plugin's
// own point of view:
//
// 1. Auth and roles are enforced by the GATEWAY. A plugin that forgets to
// declare roles gets admin-only, not open — the failure mode of "public by
// omission" is an internet-scannable endpoint inside the gateway process.
// 2. A handler error is a value, never a panic. The pcall guard is the same one
// the hooks use, for the same reason.
// 3. The plugin cannot steer the gateway's own response framing: a nonsense
// status becomes a 500, and Content-Length / hop-by-hop headers are dropped.
//
// These tests drive the declaration layer and the response writer directly; the
// router-level dispatch is covered in the gateway package.

// ShardCall runs one exported function across N private VMs and returns the
// results in the order the calls were given.
//
// Why this exists, measured on a 20-source gateway:
//
// one probe, no contention 1.4 – 3.3 s
// 20 probes via Promise.all 29 s wall clock
// the same 20 through one VM the SUM of all 20
//
// The page was written to fire its probes concurrently, and the browser really
// did send twenty requests at once. They serialised anyway, in Plugins.Call,
// which holds the plugin mutex for the whole call — including the network wait
// inside the Lua function. A mutex around one Lua VM is not optional: the VM has
// a single stack, so two concurrent calls would corrupt it. The fix cannot be
// "drop the lock".
//
// What it can be: give each concurrent call its OWN VM, running the SAME plugin
// source. Measured with a 300ms local endpoint, 8 shards:
//
// shared VM, 8 in sequence 2.407 s
// 8 independent VMs 0.304 s → 7.9x
//
// A busy-wait version of the same spike reported only 2.3x, which was measuring
// core contention on a loaded box rather than the lock. Network I/O is what the
// plugin actually does, so network I/O is what the spike has to use.
//
// Why a private VM per call rather than a pool: a pool with a bounded size
// still queues, and the queue is exactly the symptom being fixed. Booting a VM
// is ~0.1ms, so a pool would buy nothing a fresh VM does not.
//
// What a shard VM must NOT do:
//
// - Touch PLUGIN.state. State lives in the Lua VM, and every shard would hold
// its own copy of it. The billing plugin's totals would diverge per shard
// and the saver would write whichever copy it happened to see. A shard is
// therefore for READ-ONLY, idempotent work: a probe, a query, a computation.
// - Register hooks. Hooks are the shared VM's job; a shard that registered one
// would simply never be asked, which is a confusing way to lose it.
//
// The plugin decides whether a function is shardable by being listed. There is
// no inference: a function that mutates state and is mistakenly listed would
// write to a copy that is thrown away, silently.

-- usage:按调用者 key 汇报用量,供 OpenAI 兼容前端展示。
--
-- 为什么需要它
-- ------------
-- /v1/usage 不是网关的端点,但 OpenAI 兼容网关普遍提供它,第三方前端(如
-- AI Image Workbench)在启动时读它来显示「已用 X,Y 次」。缺了它,界面显示
-- 「后台未开放消费接口」——看起来像坏了,而不是像没配。
--
-- 为什么做成插件而不是网关路由
-- --------------------------------
-- 插件 HTTP 路由只能挂在 /api/plugins/http/ 之下,不能占 /v1/usage(这是刻意
-- 的:让插件无法遮蔽 /api/keys、/api/stats,便于整体撤销)。而「这是可插拔的
-- 便利功能、不是网关核心」正是它的性质。所以:
-- 插件注册 GET /usage
-- 部署侧的 nginx 把 /v1/usage 转发过来
-- 网关内核零改动,删掉插件就恢复原状。
--
-- 数据来源与归属
-- --------------
-- 取自己的 /api/stats —— 它已按调用 key 隔离(实测:user key 231 次 = 自己的,
-- admin 33847 次 = 全量)。
--
-- ★ 必须传**掩码**,不能传完整 key。
-- /api/stats 的统计 map 以 keyID(req.Key)(即 "***f9a9ed")为键 —— by_key
-- 返回的就是它,面板传的也是它。而 admin 身份下 ?key= 接受任意值:传完整 key
-- 会查不到,拿到零值。实测:
-- ?key=***f9a9ed → total.reqs=33847
-- ?key=sk-gw-7ffe…9ed → total.reqs=0
-- (这一版还暴露了网关一个 nil 解引用崩溃,已单独修掉,见提交 af977ef。)
--
-- 掩码的算法:末 6 位,前面替换为 ***;不足 6 位的 key 原样返回。与网关
-- internal/gateway/server.go 的 keyID() 一致。
--
-- total 为什么是 token 而不是金额
-- ------------------------------
-- 网关的 /api/stats 只有 token 与请求数,没有金额。金额在 billing 插件手里,
-- 但那是 admin 面板口径:实测 user key 取 billing state 拿到的仍是全量
-- (total.cost 与 admin 相同),按 key 取金额需要改 billing 插件本身。
-- 宁可少给一个数,也不给一个归属错误的数 —— 后者会让用户以为花了多少钱,
-- 而那个数是全站总量。
--
-- 字段形状取自 OpenAI 兼容惯例与前端实际读取的键:
-- total / total_usage / used / amount / cost ← 前端按顺序取第一个非空的
-- requests / request_count / count ← 同上
-- 这里给 total 与 requests,并在 usage 里附明细,便于排障。

-- 任何非 admin 拿到 403 “this endpoint declares no roles”)。

// adapter writes a negative with no `unready` field — indistinguishable, by
// truthiness, from a provisional one whose set happens to be empty. Reading it as
// provisional made an ordinary streak into a non-backing-off entry, which is the
// other half of the same live symptom.
//
// It is NOT fixable by "do not memoise a skip": on a real OpenDesign host the
// other three adapters answer 404 ("no dashboard here"), which is durable and
