CountTextToken 统计文本的token数量，仅OpenAI模型使用tokenizer，其余模型使用估算

CreateBodyStorage 根据数据大小创建合适的存储

DefinedModes returns each distinct mode on the protocol in host-table order.

DispatchPlatformUpdate 按平台分发轮询更新

--------------------------------------------------------------------------- Read accessors (hot path, must be fast) ----------------------------------

GetConsoleSetting 获取 ConsoleSetting 配置实例

GetDiskCacheDir 获取统一的磁盘缓存目录 注意：每次调用都会重新计算，以响应配置变化

GetDiskCachePath 获取磁盘缓存目录

GetModelPrice 返回模型的价格，如果模型不存在则返回-1，false

GetTaskPluginSyncSnapshot returns the enabled override set together with a deterministic revision of every active database override. Nodes can compare

GetToolPrice is a convenience wrapper when no model name is needed.

GetToolPriceForModel returns the price ($/1K calls) for a tool given a model name. Lookup: longest prefix match → tool default → 0.

GetUsernameById gets username from Redis first, falls back to DB if needed

LoadFileSource 加载文件源数据 这是统一的入口，会自动处理缓存和不同的来源类型

LookupDeclaredRoute resolves a manifest path declaration. It does not match an incoming concrete URL; runtime matching is delegated to Gin.

OpenaiImageHandler handles non-streaming OpenAI image responses (generations/edits), returning the parsed usage for billing.

PreConsumeBilling 根据用户计费偏好创建 BillingSession 并执行预扣费。 会话存储在 relayInfo.Billing 上，供后续 Settle / Refund 使用。

ProtocolSupports reports whether the named protocol claim includes mode.

Register registers an OAuth provider with the given name

RelayTaskSubmit 完成 task 提交的全部流程（每次尝试调用一次）： 刷新渠道元数据 → 确定 platform/adaptor → 验证请求 → 估算计费(EstimateBilling) → 计算价格 → 预扣费（仅首次）→ 构建/发送/解析上游请求 → 提交后计费调整(Adju

ShouldPreserveThinkingSuffix 判断模型是否配置为保留 thinking/-nothinking/-low/-high/-medium 后缀

TryReserveUserQuota atomically checks and deducts a user's wallet quota. 缓存命中时以缓存余额为准（避免批量模式下过期的数据库余额放大并发超扣）； Redis 异常或水合失败时降级为数据库条件更新，保证服务可用。

UpdateAbilities updates abilities of this channel. Make sure the channel is completed before calling this function.

UpdateUserBindColumn 第三方账号绑定字段的专用更新。 绑定操作必须只写绑定列：若改为“读取完整用户 → 改一个字段 → 整体更新”， 读快照期间并发发生的封禁、降权或分组变更会被旧快照覆盖恢复。 角色、状态、分组只允许通过各自带锁/CAS 的专用方法修改。

asciiFold maps only 'A'–'Z' onto 'a'–'z'. Every other byte is unchanged. Unicode case folding is intentionally not applied: U+212A (KELVIN SIGN) must

buildQueryParams builds query parameters for GET requests

cacheGetTokenByKey 从缓存读取 token；不完整的哈希（如仅有配额字段）会被拒绝。
