Existing interface
The route ai.nutsnews.com forwards through the existing tunnel to the loopback local AI API on port 8788. Ollama listens on port 11434 and provides qwen2.5:3b.
Authentication and requests
Authenticated requests use the x-nutsnews-ai-key header. Existing endpoints include GET /health, GET /stats, POST /review, and POST /translate. Translation language support is defined by the deployed API; the compatibility probe uses French.
Release gate
Verify health and model availability, send a synthetic translation request, and require provider=local, model=qwen2.5:3b, and a successful response. Record duration without recording prompt or response contents. Compare the AI service process identity before and after unrelated releases.
Worker path
Check production-worker configuration and connectivity from its deployment environment. A direct developer-machine probe establishes endpoint health but is not a substitute for evidence from the worker path.
Cloudflare Workers compatibility probe
A dedicated authenticated compatibility worker calls the unchanged production AI route from the Cloudflare Workers runtime. Deployment verifies local-provider and Qwen-model identity before and after changes. The probe has no schedules, database writes, or production worker configuration changes.
