oyi77	c5003665c3	fix(translator): remove thoughtSignature from functionCall parts in all Gemini translators HTTP 400 "invalid argument" was triggered when OmniRoute translated tool calls to Gemini format, because thoughtSignature was injected onto every functionCall part unconditionally. Affects two code paths: 1. openai-to-gemini.ts — OpenAI tool_calls → Gemini functionCall 2. claude-to-gemini.ts — Claude tool_use blocks → Gemini functionCall thoughtSignature is only valid on thinking/reasoning parts (those with thought: true or thoughtSignature as their primary field). When present on a functionCall part, the Gemini API returns HTTP 400 'invalid argument'. The thinking parts that legitimately carry thoughtSignature (emitted when a message has reasoning_content / thinking blocks) are untouched. Regression tests (T43) cover: - single tool call: no thoughtSignature on functionCall part (openai path) - multiple tool calls: none carry thoughtSignature (openai path) - thinking regression guard: thoughtSignature still on thought parts - claude-to-gemini path: tool_use blocks produce clean functionCall parts Fixes #724	2026-03-29 08:48:58 +07:00
