// Regression guard for #8231: the standard Gemini API surface (non-Antigravity)
// unconditionally injected HARM_CATEGORY_CIVIC_INTEGRITY into the default
// safetySettings, which upstream dynamic validation rejects for some
// models/endpoints with `safety_settings[4]: element predicate failed` — a hard
// 400 on every request through that model. #5003 already fixed this for the
// Antigravity/Cloud Code surface (open-sse/executors/antigravity.ts); this test
// pins the same behavior for claude-to-gemini.ts and openai-to-gemini.ts.
