## Kabyle Translation Models

| Code | Name | Directionality |
|------|------|----------------|
| `kab` | Kabyle | **Bidirectional** with English: `en↔kab` |
| `kab_os` | Kabyle (OS) | **One-way only**: `en→kab_os` |
| `kab_comp` | Kabyle (Tasenselkimt) | **One-way only**: `en→kab_comp` |
| `kab_comp2` | Kabyle (TSSLKMT51000) | **One-way only**: `en→kab_comp2` |
| `kab_num` | Kabyle (num40000) | **One-way only**: `en→kab_num` |
| `kab_kab` | Kabyle 48500 (19082025) | **One-way only**: `en→kab_kab` |

### Directionality Rules

- **Standard Kabyle (`kab`)**: Full bidirectional support with English.
  - `en→kab` ✓ (English to Kabyle)
  - `kab→en` ✓ (Kabyle to English)

- **Alternative Kabyle Models**: English can translate **into** these models, but they **cannot** translate back to English.
  - `en→kab_os` ✓ | `kab_os→en` ✗
  - `en→kab_comp` ✓ | `kab_comp→en` ✗
  - `en→kab_comp2` ✓ | `kab_comp2→en` ✗
  - `en→kab_num` ✓ | `kab_num→en` ✗
  - `en→kab_kab` ✓ | `kab_kab→en` ✗

## Important Notes
- The Space may go to sleep after inactivity (cold start ~30s)
- Suggestions are stored in the dataset `boffire/libretranslate-en-kab-suggestions`
- Language code `kab` refers to the standard bidirectional Kabyle model
- All alternative models (`kab_os`, `kab_comp`, `kab_comp2`, `kab_num`, `kab_kab`) are **English-to-Kabyle only**
