 - **统一路由内核**：所有协议入口统一汇聚到 `internal/server/router.go`，并在同一路由树中注册 OpenAI / Claude / Gemini / Admin / WebUI 路由，避免多入口行为漂移。
 - **统一执行链路**：Claude / Gemini 入口先经 `internal/translatorcliproxy` 做协议转换，再进入 `openai.ChatCompletions` 统一处理工具调用与流式语义，最后再转换回原协议响应。
 - **适配器分层更清晰**：`internal/adapter/{claude,gemini}` 负责入口/出口协议封装，`internal/adapter/openai` 负责核心执行，DeepSeek 侧调用只保留在 OpenAI 内核中。

-### 3.X Architecture Changes (vs older releases)
-
-- **Unified routing core**: all protocol entries are now centralized through `internal/server/router.go`, with OpenAI / Claude / Gemini / Admin / WebUI routes registered in one tree to avoid multi-entry drift.
-- **Unified execution chain**: Claude/Gemini entries are translated by `internal/translatorcliproxy`, then executed through `openai.ChatCompletions` for shared tool-calling and stream semantics, then translated back to the client protocol.
-- **Cleaner adapter boundaries**: `internal/adapter/{claude,gemini}` handles protocol wrappers, while `internal/adapter/openai` remains the execution core; upstream DeepSeek calls are retained only in the OpenAI core.
-- **Tool-calling parity across runtimes**: Go (`internal/toolcall`) and Vercel Node (`internal/js/helpers/stream-tool-sieve`) share aligned parsing/anti-leak semantics, now centered on XML/Markup-family payloads (`<tool_call>` / `<function_call>` / `<invoke>` / `tool_use` / antml variants).
-- **Config/runtime separation**: static config (`config`) and runtime policy (`settings`) are managed independently via Admin APIs, enabling hot updates and password rotation with JWT invalidation.
-- **Streaming behavior upgrade**: `/v1/responses` and `/v1/chat/completions` now share a more consistent incremental tool-call emission strategy across SDK ecosystems.
-- **Improved operability**: `/healthz`, `/readyz`, `/admin/version`, and `/admin/dev/captures` form a tighter post-deploy diagnostics loop.
