 A zero-dependency, high-performance Go proxy server that introspects any Gradio chat space (such as Hugging Face Spaces or custom deployments) and exposes a standards-compliant OpenAI `/v1/chat/completions` and `/v1/models` HTTP API.

 ## Features
 
-- **Zero External Dependencies**: Pure Go standard library (`net/http`, `encoding/json`, `bufio`, etc.).
-- **Automatic Space Introspection**: Dynamically queries `/gradio_api/info`, `/config`, and Hugging Face space metadata to discover models, endpoints, and input parameter mappings.
-- **Native Tencent Hunyuan 3 (`tencent-hy3`) Support**:
+- **Zero external dependencies**: Pure Go standard library (`net/http`, `encoding/json`, `bufio`, etc.).
+- **Automatic space introspection**: Dynamically queries `/gradio_api/info`, `/config`, and Hugging Face space metadata to discover models, endpoints, and input parameter mappings.
+- **Native Tencent Hunyuan 3 (`tencent-hy3`) support**:
   - Full native zero-degradation handling for official spaces like `https://tencent-hy3.hf.space`.
   - Maps `functions_json_str` natively without polluting the system prompt.
   - Preserves multi-turn reasoning content and tool call history in standard OpenAI message schemas.
   - Maps `reasoning_effort` (`no_think`, `low`, `high`) directly to `think_level`.
-- **Universal Multi-turn Handling**:
+- **Universal multi-turn handling**:
   - Automatically formats conversation history into structured inputs when the space supports them.
   - Transparently composes multi-turn dialogue (`System`, `User`, `Assistant`) into single prompt inputs when the space only accepts a single message textbox.
   - Automatically pads hidden/State inputs (e.g. Gradio State components) to prevent backend argument count mismatches.
-- **Real-Time Streaming & Accumulation Filter**:
+- **Real-time streaming & accumulation filter**:
   - Automatically computes token deltas from cumulative or incremental Gradio SSE output streams (including 2D Hy3 frames `[[content, reasoning, tool_calls, history]]`).
   - Emits standards-compliant `chat.completion.chunk` SSE events in real time.
-- **Thinking & Reasoning Token Separation**:
+- **Thinking & reasoning token separation**:
   - Streams native reasoning chunks as `delta.reasoning_content` in real time.
   - Detects `<think>...</think>` tags in real time as fallback for standard spaces.
   - Separates reasoning into `delta.reasoning_content` (streaming) and `message.reasoning_content` (non-streaming).
   - Keeps `content` clean without tag leakage.
-- **Full Tool Calling & Function Interception**:
+- **Full tool calling & function interception**:
   - Formats schemas into native `functions_json_str` (Hy3) or system prompts (standard spaces).
   - **`StreamToolCallFilter`**: Stateful sliding-window filter that prevents `<tool_call>` tags from leaking into `delta.content`. Emits structured OpenAI `delta.tool_calls` chunks and sets `finish_reason: "tool_calls"`.
   - Seamlessly maintains multi-turn context when tool results are submitted back via `role: "tool"`.
-- **Built-in SOCKS5 Proxy Client**:
+- **Built-in SOCKS5 proxy client**:
   - Full RFC 1928 / RFC 1929 implementation with domain resolution (`socks5h://`), IPv4, IPv6, and username/password auth.
-- **Dynamic Space Override**:
+- **Dynamic space override**:
   - Switch the target Gradio space on-the-fly per request using the `X-Gradio-Space` or `X-Space-URL` HTTP headers.
-- **Fibonacci Retry Engine**:
+- **Fibonacci retry engine**:
   - Resilient backoff retry mechanism (1s, 1s, 2s, 3s, 5s) for transient network hiccups.
