Start the normal server when template api-keys are detected, but keep proxy API endpoints disabled until the keys are updated.
Show the warning page on / and /management.html, add a button to open the management panel via /management.html?safe-mode=configure, and remove the old warning-only server path.
Fixes#4063
Enhance reasoning content retrieval by falling back to 'reasoning' if 'reasoning_content' is absent or empty.
In some selfhosted openai-like server serving deepseek, the response.delta may contains reasoning rather than reasoning_content. So the client like codex does not recognize the thinking process.
Use the aidev_client parenthetical suffix for default Antigravity UA and
route loadCodeAssist through the short UA. Keep onboardUser on the long UA
with google-api-nodejs-client.
Recognize model-visible output_text even when message.role is user, accept
assistant string content, and preserve raw merged text without trimming.
Always merge the adjacent visible item into native Gemini reasoning turns so
trailing output is not dropped by prefill stripping.
Build Gemini-native model contents for reasoning items when the routed model
uses the Gemini signature provider: thought summary on a thought part and the
replay signature on the adjacent visible part. Merge following assistant
visible text when it is not trailing prefill, and keep reasoning history when
stripping trailing model-authored prefill.
Extend Responses translator tests for signature compatibility and Antigravity
wrapper coverage; clarify stale replay signature expectations in executor tests.
