Issue facts

• Actual behavior: a mixed upstream OpenAI SSE delta loses content during Claude stream conversion; a mapped Claude public name uses locked output ratio 5 despite an explicit ratio of 3.375001140625.
• Impact: assistant replies can lack their opening text; mapped local models can consume excess output quota.
• Frequency: the rc.40 thinking-stream reproduction lost the requested prefix in 9/12 calls; non-stream and thinking-disabled stream retained it in 3/3 each. Isolated rc.40 billing reproduced ratio 5 in one request; the resolver branch is deterministic.
• Evidence that the problem is in new-api rather than the client or upstream: raw upstream SSE had both reasoning_content and content with the full prefix; raw New API SSE lacked that prefix even on localhost. The baseline consume log showed is_model_mapped=true, completion_ratio=5, and quota 11 with an explicit configured ratio of 3.375001140625.
• Applicable types and their fields (relay / billing / frontend / deployment; write "not applicable" otherwise): relay POST /v1/messages, OpenAI-compatible upstream, stream=true, thinking enabled, pass-through off; billing 58 input / 27 output tokens, model ratio 0.0547945, group ratio 1, expected pre-rounding quota ≈8.17 versus observed 10.58 before rounding; frontend not applicable; Docker/Linux ARM64/SQLite rc.40 baseline.

Change

同一 OpenAI delta 内依次发出非空的思考、正文和工具调用，并按 Claude 事件协议切换内容块。计费时仅在渠道确实映射了模型名称、且管理员明确配置输出倍率时使用该配置；未映射模型仍保留原有锁定倍率。价格修复按映射状态判断，不写死两个 Claude 别名。

Research

Duplicate / prior art

• Search queries (issues, PRs): reasoning_content content Claude stream, Claude completion ratio model mapping, 模型映射 倍率 Claude.
• What already existed and why this is not a duplicate: Bug: /v1/messages streaming for qwen3.6-plus lacks content_block_stop/message_delta/message_stop, causing Claude Code to hang #4697 是缺失终止事件，fix: preserve Gemini thought and content in same chunk #5094 是 Gemini 转换；未找到同时处理本转换器同帧正文丢失与映射模型倍率的 PR。

Docs and code

• https://docs.newapi.ai/ : Claude Messages API 说明 /v1/messages 可转换上游协议；倍率设置 说明可配置补全倍率。
• https://deepwiki.com/QuantumNous/new-api : 查阅 Request Format Conversion 与 Pricing & Ratio System 入口，并以当前源码为准。
• README / repo docs: README.md 列出跨协议转换与使用量计费。
• Code paths and what they imply for this change: to_claude_messages_resp.go 的互斥分支丢弃同帧正文；model_ratio.go 按公有名称锁定倍率；relay/helper/price.go 可读取实际渠道映射状态。

Alternatives considered

• Option A: 根据缺失的开头词语补文本；无法还原任意长度内容，也无法处理工具调用。
• Option B: 全局取消 Claude 名称的锁定倍率；会改变未映射官方模型的计费。
• Why this approach: 在转换边界保留所有字段，并只对已映射的模型采用明确配置的输出倍率。

Files

Path	Why
relaykit/relayconvert/internal/oai_chat/to_claude_messages_resp.go	逐项发出混合流字段。
relaykit/relayconvert/internal/oai_chat/to_claude_messages_resp_test.go	固定同帧思考、正文、工具调用的事件序列。
setting/ratio_setting/model_ratio.go	为映射模型读取明确配置的输出倍率。
relay/helper/price.go	仅在实际发生渠道模型映射时启用该读取方式。
relay/helper/price_test.go	通过真实映射辅助函数验证映射/未映射计费分支。

Behavior

• Before: 混合 SSE 帧丢失正文；claude-sonnet-4-5 映射到本地模型仍按输出倍率 5 计费。
• After: SSE 内容块完整；上述映射在显式配置 3.375001140625 时按该倍率计算，未映射同名模型仍用 5。
• Explicit non-goals / leftover work: 不改上游生成内容、默认官方模型定价、数据库结构或前端；全局模型价格预览没有渠道上下文，仍可能显示未映射时的锁定倍率。

Verification

• Commands and results: cd relaykit && GOWORK=off go test ./relayconvert/... -count=1：转换器各测试包通过，包括新增的混合帧断言；cd relaykit && GOWORK=off go build ./...：独立模块编译通过。GOWORK=off go test ./relay/helper ./setting/ratio_setting -count=1：两包通过；映射 Sonnet/Opus 使用 3.375001140625/3.5，未映射同名模型和无显式配置的映射模型保持 5。GOWORK=off go test ./relay/channel/openai -count=1：通过。GOWORK=off go build ./relay/... ./setting/...：通过。git diff --check：无空白错误。
• Manual steps and observed result: rc.40 未修复时，真实上游 SSE 同帧提供完整正文，New API thinking-stream 9/12 丢开头；原版 rc.40 隔离计费调用返回 HTTP 200，58/27 tokens 的消费日志记录倍率 5、quota 11。相同流式转换补丁在隔离实例用固定混合 SSE 帧验证，思考、正文、工具参数和内容块结束事件均完整；真实 Qwen 的隔离和生产流式测试分别 3/3 和 6/6 保留开头。PR 的映射感知计费变体仅在当前 main 的 Go 回归测试中验证，尚未部署。
• UI: 无截图；本 PR 不修改 UI。
• Tests added or updated, or why none: 扩展已有 Claude 流转换测试与价格辅助函数测试。
• Databases / providers / platforms exercised: SQLite 和本地 OpenAI-compatible Qwen 用于 rc.40 现场复现；当前 main 的 Go 测试运行于 Linux x86_64。
• Not verified: MySQL、PostgreSQL、其他上游提供商及当前 main 的完整 Web 打包运行。GOWORK=off go build ./... 因干净源码树缺少 web/dist 无法编译 main.go 的嵌入资源；本机也未安装 Bun。受影响的 Go 包和独立 relaykit 已编译。

Risks

• Failure modes: 映射渠道的明确输出倍率现在优先于同名官方模型的锁定值；需要管理员为本地上游正确设置该倍率。流转换在一个上游帧中可能发出多个 Claude 事件，已有测试检查顺序和结束事件。
• Billing / quota / auth impact: 只改变实际模型映射且存在显式倍率时的 legacy 输出倍率；固定价格和 tiered-expression 路径不变；认证不变。
• Follow-ups: 若维护者希望拆分审查，两个提交可以分别形成流转换与计费 PR。

Scope check

• Single focused change: yes — 修复 Bug: mapped Claude model loses mixed stream text and ignores configured output ratio #7664 所述映射 Claude 请求的两个可独立审查的症状，分别提交。
• Secrets included: no
• Out of scope (Coding Plan / reverse-engineered channel / third-party wrapper / Codex / pass-through-only forwarding): no

Summary by CodeRabbit

• Bug Fixes
  • Corrected completion-ratio billing for mapped model aliases when a specific ratio is configured; aliases without a configured ratio continue to use the default.
  • Streaming responses now preserve reasoning, text, citations, and tool-call data when these arrive in different orders, including text between tool-argument updates.
  • Improved completion handling so buffered content is delivered when a stream ends, with usage, stop reasons, and completion state preserved.

Walkthrough

The PR updates Claude stream conversion to retain reasoning, text, annotations, and tool-call data across mixed stream chunks. It also selects configured completion ratios for mapped models when channel metadata is present.

Changes

Claude stream conversion

Layer / File(s)	Summary
Stream block helpers and pending delta state relaykit/relayconvert/convmeta/meta.go, relaykit/relayconvert/internal/oai_chat/to_claude_messages_resp.go	The conversion metadata stores pending non-tool deltas. Shared helpers close blocks, emit reasoning, text, and citations, and flush pending deltas.
Stream delta processing and finalization relaykit/relayconvert/internal/oai_chat/to_claude_messages_resp.go, relaykit/relayconvert/internal/oai_chat/to_claude_messages_resp_test.go	The converter buffers non-tool deltas while tool blocks are active and flushes them before terminal events and pending tools. Tests cover mixed deltas, interleaved text and tool arguments, and usage-only or EOF termination.

Mapped model pricing

Layer / File(s)	Summary
Mapped completion ratio selection setting/ratio_setting/model_ratio.go, relay/helper/price.go, relay/helper/price_test.go	The ratio helper returns an explicitly configured completion ratio or falls back to the regular ratio. Pricing uses the mapped ratio when channel metadata is present and the model is mapped. Tests cover configured and fallback ratios.

Merge Risk: ⚪ Minimal · up to 637d6

The change preserves mixed reasoning, text and tool-call content in Claude streams and applies configured completion ratios to mapped models. No outstanding merge-blocking issue was found.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 637d6

The new delayed-response buffer has no cumulative size limit in the reviewed path. A hostile upstream could increase memory pressure while keeping a stream active. Existing cancellation and per-event limits provide containment, but do not bound accumulated content.

Retained concerns

• Medium · security · inferred: While a tool block remains active, every nonempty text, reasoning, or raw annotation delta is retained without a cumulative byte or entry limit. A hostile configured upstream can repeatedly send annotation-only frames without finishing, growing retained memory independently of the existing text-based token-accounting buffer. Terminal flushing, cancellation, and per-line limits mitigate finite or interrupted streams, but do not bound accumulation during continued input. Availability impact on other requests sharing the process is inferred, not experimentally verified.

Security review details

Security Blast Radius

• inferred — The identified exposure is availability of the process performing conversion. Concurrent affected streams can compound memory pressure and potentially affect unrelated requests sharing that process. Tenant, replica, and environment scope cannot be determined from the supplied topology evidence.

Security Findings and Attack Paths

• inferred — A hostile upstream can open a tool block, then emit repeated nonempty annotation deltas without a finish reason. Those bytes accumulate until a flushing transition occurs, and continued input resets the scanner's idle timer. This supports an inferred resource-containment concern, not a verified exploit or proof that an unauthenticated consumer controls upstream output.

Trust Boundaries and Controls

• observed — The scanner applies a configurable per-line limit, defaulting to 128 MiB, and bounds its handoff channel to ten entries. Idle timeout and client cancellation stop upstream reading. These are useful controls, but neither the line limit nor the bounded handoff channel limits the downstream session queue's accumulated bytes.

Resilience and Maintainability Implications

• observed — Normal flushing clears pending entries and terminal completion is guarded against repetition. The inspected host final-response helper instead reconverts the last frame and sets Done; it does not unconditionally invoke the explicit finalizer. Consequently, explicit-finalizer cleanup guarantees cannot be assumed for every interrupted or malformed stream, although scanner cancellation closes the upstream body.

Hardening Proposals

• proposed — Define a cumulative byte and entry budget for deferred content, including raw annotations. On overflow, terminate explicitly rather than silently discarding content. Define failure and cancellation cleanup separately from successful finalization so pending state is released without manufacturing successful terminal output.

- Around line 270-272: Update the text-content branch in the stream conversion
flow so mixed text-and-tool frames do not call stopOpenBlocksAndAdvance while a
tool argument is incomplete. Preserve the tool identity maps and keep the tool
block open until all argument fragments have been emitted, then close it
normally; add a regression case for an argument split across a mixed
text-and-tool frame.
