关联 #7465。

背景

PreviewModelPricingConversion 对部分模型报 The model routing configuration could not be verified.。实际原因是元数据 endpoints 的解析形状问题，与具体模型、渠道、路由都无关。

根因

model/model_metadata_sync.go 的校验注释里明确 endpoints 有两种合法形态：

• map 形式（自定义路径）
• type-array 形式（声明的协议类型），例如 ["gemini","openai"]

但转换预览只按 map[string]any 解析（model/model_pricing_conversion.go）：

var endpoints map[string]any
if err := common.UnmarshalJsonStr(entry.Endpoints, &endpoints); err != nil {
    return &ModelPricingConversion{UnsupportedReason: "The model routing configuration could not be verified."}, nil
}

于是校验层放行的数组形式，到转换层必然解析失败，落到这句与真实原因无关的报错上。

这也解释了它为什么难以复现：只有当某个模型在 models 表里存在一行 endpoints 非空、且为数组形式的元数据时才触发。元数据表为空的干净实例，这段循环直接空转、转换正常 —— 所以同一个版本，不同实例表现不同（有的实例 gpt 全系列失败，有的实例 gemini/deepseek 正常）。

改动

新增 declaredEndpointNames，把两种形态统一解析为端点名列表后再进入 switch。

修复过程中踩到一个坑一并写进了注释：切片上用 for endpoint := range 拿到的是下标（int 可隐式转为 string，会静默错配、switch 永不命中）。因此切片分支显式取值，map 分支仍迭代 key。

测试

新增 TestModelPricingConversionAcceptsDeclaredEndpointArray，6 个用例覆盖数组 / 映射两种形态，并断言声明的 image-generation 端点确实进入计费分支（ImageCount）—— 只用"表达式非空"这类松断言会漏掉端点名错配的情况。

验证

• 单元测试：go test ./controller/ -run TestModelPricingConversion 通过。
• 生产实例（元数据为数组形式）：修复前该批模型全部报 unsupported_reason；修复后正常转换，逐变量比对新旧计费系数完全等价（迁移前后费率不变）。

未改动（同类问题，建议单独评估）

model/pricing.go 里另有两处对 meta.Endpoints 的 map[string]any 解析，同样是 map-only，解析失败时静默跳过、不报错。后果是数组形式声明的协议不会进入模型广场的 supported_endpoint 推断；由于渠道能力通常已能推断出相同结果，目前尚未暴露。该改动会影响模型广场的端点展示，本 PR 不包含，留待单独评审。

Summary by CodeRabbit

• Bug Fixes

  • Pricing conversion now recognizes endpoint metadata provided as either a list of endpoint names or a map, including image, Gemini, and OpenAI endpoint declarations. Endpoint names with surrounding whitespace are handled.
  • Invalid or unsupported metadata retains the existing unverified-routing outcome.

• Tests

  • Added coverage for supported metadata formats, successful conversion, and image-count billing behavior.

Walkthrough

Pricing conversion now reads endpoint metadata in array or map form. It trims endpoint names and preserves the existing unsupported-routing result when parsing fails. Tests cover supported metadata forms and image-count billing.

Changes

Pricing conversion

Layer / File(s)	Summary
Parse endpoint metadata and verify conversion model/model_pricing_conversion.go, controller/model_pricing_conversion_endpoints_test.go	The conversion path parses endpoint metadata as an array of names or a map of endpoint keys. Parsing failures retain the existing unsupported-routing result. Tests check successful conversion and image-count billing for supported metadata forms.

跟进 review 的意见补了一个 commit（5c82c98）。

问题确认：model/model_pricing_conversion.go:165 数组分支用 trim 后的值做校验、却 append 了原值。于是 ["image-generation "] 这种带尾随空格的名字能通过校验，但在下游 switch 里匹配不到任何分支 —— 若该模型同时是固定价格，转换结果会从 image_count 计费静默退化成按次计费。map 形式的 key 有同一类问题。

改动：declaredEndpointNames 内对两种形式都做归一化（数组元素 trim 后存入；map key trim 后跳过空值），并补 2 个回归用例（数组 padded / map padded）。

验证：

• gofmt -l 干净；go test ./controller/ -run TestModelPricingConversionAcceptsDeclaredEndpointArray 8/8 通过。
• 做了反向验证：只回退 model/ 的改动、保留新用例，两个 padded 用例如期失败并产出 tier("request", fixed(1))（错误值）；恢复修复后为 tier("image", fixed(1)) * image_count。所以这不是装饰性测试。

补充一句实证：我们线上实例的模型元数据里没有带空格的 endpoint 名，所以这条属于主动加固，不是线上故障修复。
