## 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`
