Request Processing

1. Client sends request to /v1/*
2. Route handler calls handleChat, handleEmbedding, handleAudioTranscription, or handleImageGeneration
3. Model is resolved (direct provider/model or alias/combo)
4. Credentials selected from local DB with account availability filtering
5. For chat: handleChatCore — format detection, translation, cache check, idempotency check
6. Provider executor sends upstream request
7. Response translated back to client format (chat) or returned as-is (embeddings/images/audio)
8. Usage/logging recorded
9. Fallback applies on errors according to combo rules

Authentication

• Dashboard routes (/dashboard/*) use auth_token cookie
• Login uses saved password hash; fallback to INITIAL_PASSWORD
• requireLogin toggleable via /api/settings/require-login
• /v1/* routes optionally require Bearer API key when REQUIRE_API_KEY=true
