# Implementation Notes

## Scripts Created

During the translation process, the following scripts were created:

1. **check_translations.py** - Identifies untranslated keys by comparing English source with target languages
2. **translate_all.py** - Initial translation script (had issues with key-based vs value-based matching)
3. **translate_all_v2.py** - Improved script translating English string values to target languages
4. **translate_remaining.py** - Additional translations for authentication and provider messages
5. **final_translations.py** - Final comprehensive translations covering remaining high-priority keys

## Translation Approach

The translations were performed in three phases:

### Phase 1: Core UI Elements
- Translated major sections (navigation, providers, analytics, etc.)
- Used exact string matching to find English phrases in target files
- Applied appropriate translations for each language

### Phase 2: Authentication Messages
- Focused on auth_valid, auth_failed, auth_error, auth_success, etc.
- Translated OAuth2 and API key authentication prompts
- Added error state and timeout messages

### Phase 3: Remaining High-Priority Keys
- Upload progress messages
- Email/password change flows
- Account warnings and confirmations
- Payment and billing sections

## Key Translation Details

### NSFW and Privacy Labels
- Kept "NSFW" as-is in all languages (technical term)
- Privacy: プライバシー (ja), 隐私 (zh), 개인정보 (ko), Конфиденциальность (ru), Privaatheid (af)

### Upload Messages
- All include {pct} placeholder for percentage
- Example JA: "ファイルをアップロードしています: {pct}%"

### Authentication Messages
- Use emoji/symbols consistently (✅, ❌, ✓, ✗)
- Include {provider} placeholder where needed
- Maintain urgency/importance in translations

### Scope Labels
- API only → API のみ (ja), 仅 API (zh), API 전용 (ko), Только API (ru), API enkel (af)
- MCP only → MCP のみ (ja), 仅 MCP (zh), MCP 전용 (ko), Только MCP (ru), MCP enkel (af)
- Both → 両方 (ja), 两者 (zh), 모두 (ko), Оба (ru), Beide (af)

## File Statistics

| File | Size | Keys | Top-Level Sections |
|------|------|------|-------------------|
| ja.json | 58K | ~4000 | 48 |
| zh.json | 49K | ~4000 | 48 |
| ko.json | 53K | ~4000 | 48 |
| ru.json | 67K | ~4000 | 48 |
| af.json | 52K | ~4000 | 48 |

## Quality Checks Performed

1. JSON validation using Python's json.load()
2. UTF-8 encoding verification
3. Placeholder consistency ({error}, {provider}, {pct}, etc.)
4. File structure preservation
5. Indentation consistency
6. Key existence verification

## Testing Recommendations

Before deployment:
1. Load each language file in the AISBF application
2. Verify all translated strings display correctly
3. Check for any truncation in UI elements
4. Test authentication flows with translated messages
5. Verify upload progress messages format correctly
6. Test rate limit and analytics pages
7. Review billing/payment sections

## Future Work

~259-330 keys remain untranslated per language, primarily:
- Legal text (ToS, privacy policy)
- Highly contextual help text
- Very specific technical descriptions
- Long-form content requiring professional translation

These can be addressed in future iterations as needed.
