### AI Reflection Pipeline

On-device LLM generates daily reflections from journal entries:

1. **Entry collection** — `src/db/queries/entries.ts` fetches all entries for a given day (`DailyEntryObj[]`)
2. **Text conversion** — `src/utils/days/reflection/get-reflection.ts` formats entries into structured text (journal name + field labels/values)
3. **LLM inference** — `@react-native-ai/llama` downloads a GGUF model, Vercel `ai` package's `generateText()` runs inference with a system prompt
4. **Parsing** — JSON output is extracted via regex and validated with `reflectionSchema` (Zod)
5. **Storage** — Result saved to `reflections` table (one per day, keyed by midnight timestamp)

**Supported models** (defined in `src/constants/ai-models.ts`): Gemma 3 4B, Qwen 3 4B, Phi-4 Mini — all Q4_K_M quantization from HuggingFace.

**Settings** are stored in the `settings` KVS table, managed by `src/hooks/settings/use-ai-reflection-settings.ts`:

- `aiReflectionEnabled` — on/off toggle
- `aiReflectionModelId` — selected GGUF model
- `aiReflectionTime` — time of day to auto-generate (via `use-auto-reflection.ts`)

Apple Intelligence を優先するプロバイダー選択を実装する

@react-native-ai/apple は依存関係にありますが、ソースコードでは使用されていません。getReflection は常に @react-native-ai/llama を使用します。Apple Intelligence の対応時は Apple Intelligence を選択し、非対応時だけ Llama Engine にフォールバックしてください。プロバイダー選択の経路を CLAUDE.md に記載してください。
