My project Haja Luz shows GEMINI_API_KEY configured in Secrets, with Default Gemini Project and Default Gemini API Key selected and changes applied.
After a full restart, with no .env.local or manual reinjection, the code assistant reports that the Node/Vite process on port 3000 literally receives MY_GEMINI_API_KEY, confirmed by an exact internal comparison.
GET /api/luz/status returns hasGeminiKey: false. POST /api/ask-luz returns HTTP 503, CONFIG_MISSING, reference LUZ-MUXC513S-KAQ3.
How do I reapply the selected secret to the preview process? I need to verify the configuration propagation without exposing the key.
