# i18n Translation Guidelines

This document is the canonical set of conventions for translating LoRA Manager UI strings.
It applies to **human translators and AI agents** alike. Read it before editing anything in
`locales/`.

Source of truth: `locales/en.json` (10 locales, 1810 leaf keys; all locales share the exact
same key structure).

Locales: `en`, `zh-CN`, `zh-TW`, `ja`, `ko`, `fr`, `de`, `es`, `ru`, `he` (RTL).

> **Status (2026-08 sweep):** a full audit was executed and the terminology, placeholder,
> stale-text, and untranslated-block fixes described in §2–§6 were applied across all locales
> (commits `3c3ac49f` … `fd1227d3`). The tables below are now the **normative target state**,
> not a to-do list — future edits should preserve these renderings and only add what is new.

---

## 1. Hard rules (do not violate)

### R1 — Key structure is sacred
- Only `locales/en.json` may add/remove/rename keys. All other locales must keep the exact
  same nested key set. `tests/i18n/test_i18n.py` enforces this.
- When a new UI string is added to `en.json`, run
  `python scripts/sync_translation_keys.py` (adds the missing keys to all locales with
  placeholder copies), then translate the newly added keys in every locale.
- Never reorder, re-indent, or reformat a locale file "for tidiness". The sync script
  preserves formatting; manual reformatting creates noisy diffs.

### R2 — Placeholders and HTML must be preserved verbatim
- `{name}`-style placeholders must appear in the translation exactly as in `en.json`.
  Do not invent placeholders the source string does not have — the caller may not pass them
  (example bug: `zh-CN recipes.controls.import.downloadLocationPreview` added `{path}`; the
  template renders this key with no parameters, so the literal text `{path}` shows in the UI).
- `{{...}}` in a locale value is an escaped literal brace — keep it identical.
- Keep embedded HTML tags (e.g. `<strong>...</strong>`, `<code>...</code>`) intact.
  You may move the tag around the sentence if the target language needs different word order.

### R3 — Never translate or transliterate these
- Model types: **LoRA, Checkpoint, Embedding, Diffusion Model**
- Products/brands: **LoRA Manager, ComfyUI, CivitAI, CivArchive, HuggingFace, Ko-fi**
- Ecosystem names: **LyCORIS, DoRA**, trigger-adjacent jargon **Prompt, Workflow**
  (these are used as-is in the target-language SD community; see §2 per-language policy)
- Theme names: **Nord, Midnight, Monokai, Dracula, Solarized**

### R4 — The "Recipe" convention (the most important domain term)
Product intent: a *Recipe* records a **LoRA combination + generation parameters**
(prompt, seed, sampler, …) that reproduces an image style. The metaphor is a **cooking
recipe** — "follow it and you get a similar dish". It is **not** a menu, not a dish list,
not a prescription.

Decision per language — translate only into a word whose everyday primary meaning is a
cooking recipe; where that word would mislead users, **keep the English "Recipe(s)"**:

| Locale | Use | Never use |
|---|---|---|
| fr | **Recipe / Recipes** (keep English) | recette(s) — cooking reading is secondary and it was explicitly judged misleading |
| zh-CN / zh-TW | 配方 | 食谱 (reads as "food cookbook") |
| ja | レシピ | — (leftover English "Recipe" in `initialization.recipes.title` / `toast.recipes.recipeSaved` → translate) |
| ko | 레시피 | — |
| de | Rezept / Rezepte | — (cooking meaning dominant; prescription reading acceptable) |
| es | receta / recetas | — (cooking meaning dominant) |
| ru | рецепт / рецепты | — (leftover English "Recipe" in `initialization.recipes.title` / `toast.recipes.recipeSaved` → translate) |
| he | מתכון / מתכונים | — (cooking meaning dominant) |

Whatever the choice, **one concept = one noun within a locale**. Currently violated in:
- `fr` — "Recipe" (~97 keys, incl. nav) mixed with "recette" (~58 keys)
- `zh-CN` / `zh-TW` — 配方 (126/122 keys) mixed with 食谱 / 食譜 (14/17 keys, all in the
  *rematch* flow: `globalContextMenu.rematchRecipes.*`, `toast.recipes.rematch*`)
- `de` — "Rezept" (136 keys) mixed with leftover English "Recipe" (5 keys)
- `ja` / `ru` — leftover English "Recipe" in `initialization.recipes.title` ("Recipe Manager
  zu initialisieren" / «Инициализация Recipe Manager») and `toast.recipes.recipeSaved`

### R5 — One term, one rendering (within each locale)
Same source word must not be translated several ways in one file. Known offender areas
(see §5 for the full fix list): recipe, Checkpoint, Embedding, prompt, base model, preset,
workflow, hash, metadata, tags, bulk. Every locale currently mixes variants of at least one
of these — pick the preferred form in the §2 tables and normalize.

### R6 — Register consistency
- `zh-CN` / `zh-TW`: pick 你 or 您 once. Do not mix (zh-CN has 44×你 + 5×您; zh-TW has
  27×您 + 18×你).
- `de`: pick "du" or "Sie" once (currently 143×Sie + ~7×du).
- `es`: pick "tú" or "usted" once.

### R7 — Punctuation per script
- Full-width punctuation `：（）` is correct **only in CJK locales** (zh-CN, zh-TW, ja, ko).
- Latin/Cyrillic/Hebrew locales must use ASCII `: ()` — full-width colons leaked in there
  are machine-translation artifacts. Known: `fr toast.recipes.createError/createFailed`,
  `es toast.recipes.createError/createFailed` (e.g. "…de la receta：" should be "…de la receta:").
- `fr` apostrophes must be U+2019 `'` / ASCII `'`, never a straight double quote:
  `fr header.filter.allowSellingGeneratedContentTooltip` currently reads
  `vendre d"images` → fix to `d'images`. Do not mix `'` and `'` in one file (fr has 299 vs 15).
- Ellipsis: use ASCII `...` (project style). Don't introduce `…`.
- Keep the sentence-ending period/omission consistent with the source string where the
  language allows it.
- `he` is RTL: mix of Hebrew and Latin scripts is normal; keep Latin term ordering natural.

### R8 — No untranslated English leftovers
Full sentences left byte-identical to `en.json` are bugs (brand names and URL placeholders
are the exception). Every locale has them; see §6 for the per-locale checklist.

### R9 — Mirror the source even when the source is wrong
If `en.json` itself contains an inconsistency (e.g. the `Civitai` vs `CivitAI` casing split,
or the `CivitArchive` typo in `modals.relinkCivitai.helpText.format4`), translate/transcribe
it as-is in your locale and instead **fix the source** in `en.json` (then propagate by
re-syncing and re-translating affected keys). Do not silently diverge in one locale only.

---

## 2. Per-language term maps

Preferred rendering per term. "Fix" means the locale currently contains the wrong variant
and must be normalized. `en` = keep the English word as-is.

### fr

| Term | Use | Fix |
|---|---|---|
| recipe | Recipe(s) | Replace all "recette(s)" (58 keys, e.g. `recipes.actions.deleteRecipeWithShortcut`, `toast.recipes.rematchComplete`) with "Recipe(s)" |
| Checkpoint | Checkpoint | `statistics.modelTypes.checkpoint` = "Point de contrôle" → "Checkpoint" |
| trigger words | mot(s)-clé(s) | unify: `modals.model.triggerWords.editWord` uses "mot déclencheur" — pick one |
| prompt / negative prompt | Prompt / prompt négatif | — |
| base model | modèle(s) de base | — |
| preset | préréglage | unify: `modals.model.usageTips.addPresetParameter` "prédéfini", `toast.presets.restored` "par défaut" |
| hash | hash | `conflictConfirm.message` "hachage" → "hash" |
| tags | tags | `settings.sections.priorityTags` "Étiquettes" → "Tags" |
| metadata | métadonnées | `loras.controls.refresh.fullTooltip` keeps English "metadata" |
| duplicates | doublon(s) | unify with "dupliqué(e)s" |
| bulk | groupé(e) | unify with "par lot / mode lot" variants |

### de

| Term | Use | Fix |
|---|---|---|
| recipe | Rezept/Rezepte | 5 leftover English "Recipe" keys → Rezept (e.g. `globalContextMenu.repairRecipes.label`, `toast.recipes.recipeSaved`) |
| base model | pick Basis-Modell or Basismodell | currently 27× hyphenated vs 15× closed |
| metadata | Metadaten | 4 keys use "Modelldaten" (`onboarding.steps.fetch.title/content`) → Metadaten |
| bulk | pick Massen- or Sammelmodus | `loras.controls.bulk.action` = "Massen" reads as "crowds" — use "Massenbearbeitung"/"Mehrfachauswahl" |
| register | Sie (formal) | 7 keys use "du/dein" (`settings.backup.managementHelp`, `modals.checkUpdates.message/tip`, `doctor.footer`, …) |

### es

| Term | Use | Fix |
|---|---|---|
| recipe | receta(s) | — |
| Checkpoint | Checkpoint | 5 statistics keys "Punto(s) de control" → "Checkpoints" (`statistics.metrics.checkpoints`, `statistics.insights.unusedCheckpoints.*`, `statistics.modelTypes.checkpoint`) |
| trigger words | palabra(s) de activación | 2 keys already use it; ~15 keys "palabra(s) clave" (reads as search keyword) → unify |
| base model | modelo base | — |
| preset | preajuste | 3 keys keep English "preset", 1 "preestablecido" → preajuste |
| workflow | pick flujo de trabajo or workflow | currently 21× "flujo de trabajo" vs 10× "workflow" |
| bulk | masivo / por lotes | unify; "Batch Import" → traducción |
| tags | etiquetas | — |

### ru

| Term | Use | Fix |
|---|---|---|
| recipe | рецепт(ы) | English leftovers: `initialization.recipes.title`, `recipes.batchImport.*`, `toast.recipes.recipeSaved` → translate |
| Checkpoint | Checkpoint (recommended) | 3 variants today: "Checkpoint" (17 keys), «Чекпойнт», «Контрольная точка» (statistics, 6 keys) — statistics MUST drop «Контрольная точка» |
| Embedding | Embedding | «Эмбеддинг» variant exists in `settings.priorityTags.modelTypes.embedding` — unify |
| prompt | промпт | 8 keys use «запрос» (reads as "database/HTTP request") → «промпт» |
| base model | базовая модель | — |
| preset | пресет | `header.theme.presets` "Предустановки" → пресеты |
| workflow | Workflow (recommended) | «рабочий процесс» used in 4 keys — unify |
| hash | pick хеш or хэш | both spellings co-occur |
| tag(s) | тег(и) | — |
| typos | — | `settings.misc.loraSyntaxFormatHelp`: «безпотерьного» → «беспотерьного» |

### he

| Term | Use | Fix |
|---|---|---|
| recipe | מתכון / מתכונים | — |
| Checkpoint | Checkpoint | 5 statistics keys «נקודת/נקודות ביקורת» (road/security checkpoint) → "Checkpoint(s)" (`statistics.metrics.checkpoints`, `statistics.modelTypes.checkpoint`, `statistics.insights.unusedCheckpoints.*`) |
| Embedding | Embedding | `statistics` keys use הטמעות → Embedding |
| prompt | pick הנחיה or פרומפט | 9 keys הנחיה vs 3 פרומפט — unify (recommend פרומפט, SD-community loanword) |
| preset | קביעה מראש | `header.filter.presetOverwriteConfirm` uses פריסט → unify |
| hash | pick one of האש / גיבוב / hash | 3 variants co-occur — unify (recommend hash or גיבוב) |
| metadata | pick מטא-דאטה or מטא-נתונים | 38 vs 17 keys — unify |
| model | מודל | 13 keys use דגם/דגמים — unify |
| bulk | pick one of 5 variants | 5 different renderings ("כמות גדולה", "המוני", "קבוצתי", "אצווה", …) — unify; `loras.controls.bulk.action` "כמות גדולה" reads as "large quantity" |

### ja

| Term | Use | Fix |
|---|---|---|
| recipe | レシピ | `initialization.recipes.title` keeps English "Recipe Manager" — translate to レシピマネージャー |
| Checkpoint | Checkpoint or チェックポイント (pick one) | 3 variants: Checkpoint (~14), checkpoint lowercase (4), チェックポイント (4, e.g. `settings.priorityTags.modelTypes.checkpoint`) |

|---|---|---|
| recipe | 配方 (fix 食谱 → 配方, 14 keys in rematch flow) | 配方 (fix 食譜 → 配方, 17 keys in rematch flow) |

## 3. Cross-cutting confusion hot-spots (must-fix list)

All items below were **resolved** in the 2026-08 sweep — treat them as a regression
watch-list: do not reintroduce these renderings.

1. **Checkpoint rendered as a literal security/road checkpoint** — fr, es, ru, he, zh-CN,
   zh-TW all had 4–6 keys in the `statistics.*` domain reading as "control point"; reverted
   to "Checkpoint".
2. **"recipe" variants that break the one-noun rule** — fr "recette" → "Recipe", zh
   食谱/食譜 → 配方, de/ja/ru leftover English "Recipe" translated.
3. **ko `header.filter.tagLogicAny`** — was inverted ("모든 태그 일치 (OR)") and identical
   to `tagLogicAll`; now "어느 하나의 태그와 일치 (OR)".
4. **ja `modals.model.versions.actions.viewLocalTooltip`** — was the stale "近日対応予定"
   ("coming soon"); all 9 locales now describe the actual action.
5. **Stale help texts** — `settings.downloadSkipBaseModels.help`,
   `settings.aiProvider.apiBaseHelp`, `settings.hideEarlyAccessUpdates.help` retranslated
   in all locales to the current `en.json` wording.
6. **en.json source bugs** (fixed in source, then mirrored):
   - "Civitai" → "CivitAI" brand casing (values only; key names `relinkCivitai` etc. keep
     their lowercase form and must not be renamed)
   - `modals.relinkCivitai.helpText.format4` "CivitArchive" typo → "CivArchive"
   - `zh-CN recipes.controls.import.downloadLocationPreview` invented `{path}` removed

---

## 4. Placeholder contract deviations (current)

`{...}` token sets must match `en.json` per key. All deviations found in the 2026-08 sweep
were fixed, with one *intentional* exception:

**`toast.settings.mappingsUpdated`** — the caller passes a hardcoded English inflection
(`plural: count !== 1 ? 's' : ''`). Languages that cannot build a plural by appending that
`s` (zh-CN/zh-TW, ja, ko, de, ru, he) **drop `{plural}`** and render a count-friendly form
(`({count})` or a measure word); fr and es keep it (`mappage{plural}`, `mapeo{plural}`).

```python
# keep a copy of this rule next to the key if it ever moves:
#   fr/es:  "... ({count} mappage{plural})"
#   de/ru/he: "... ({count})"
#   zh-CN: "（{count} 条映射）" / zh-TW: "（{count} 個對應）" / ja: "（{count} マッピング）"
```

Do NOT add `{...}` tokens the source lacks (the caller will not supply them, and the literal
text renders in the UI), and do NOT rename source tokens (`{typePlural}` stays `{typePlural}`).

---

## 5. One term, one rendering — offender matrix

Cross-locale summary of §2 inconsistencies. "✓" = already consistent. All ✗ cells were
resolved in the 2026-08 sweep; the row shows the single rendering now in force per locale.

| Term | fr | de | es | ru | he | ja | ko | zh-CN | zh-TW |
|---|---|---|---|---|---|---|---|---|---|
| recipe | Recipe | Rezept | receta | рецепт | מתכון | レシピ | 레시피 | 配方 | 配方 |
| Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint | Checkpoint |
| Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding | Embedding |
| prompt | Prompt | Prompt | prompt | промпт | פרומפט | プロンプト | 프롬프트 | 提示词 | 提示詞 |
| base model | modèle de base | Basismodell | modelo base | базовая модель | מודל בסיס | ベースモデル | 베이스 모델 | 基础模型 | 基礎模型 |
| preset | préréglage | Voreinstellung | preajuste | пресет | קביעה מראש | プリセット | 프리셋 | 预设 | 預設 |
| workflow | Workflow | Workflow | workflow | Workflow | workflow | ワークフロー | 워크플로 | 工作流 | 工作流 |
| hash | hash | Hash | hash | хеш | hash | ハッシュ | 해시 | 哈希 | 雜湊 |
| metadata | métadonnées | Metadaten | metadatos | метаданные | מטא-נתונים | メタデータ | 메타데이터 | 元数据 | 中繼資料 |
| tags | Tags | Tags | etiquetas | теги | תגיות | タグ | 태그 | 标签 | 標籤 |
| duplicates | en double | Duplikate | duplicados | дубликаты | כפילויות | 重複 | 중복 | 重复项 | 重複項 |
| bulk | groupé | Massen- | por lotes | пакетный | בכמות גדולה | 一括 | 일괄 | 批量 | 批量 |

Watch: ja/ko keep the model-type names **Checkpoint/Embedding** and `Diffusion Model` in
Latin (consistent with their model-type sections) — do not transliterate them as
チェックポイント/체크포인트.

---

## 6. Untranslated English leftovers (status)

Values byte-identical to `en.json` that are actual UI sentences are bugs (brand names and
URL placeholders are the exception). As of the 2026-08 sweep, **all previously untranslated
blocks are translated** in every locale: `recipes.batchImport.*` + `toast.recipes.batchImport*`
(fr/de/es/ru/he/ja/ko), `banners.communitySupport.*`, `modals.model.license.*`,
`globalContextMenu.fetchMissingLicenses.*`, the `doctor.*` issue/action/label subset,
`toast.settings.libraryLoadFailed` / `libraryActivateFailed`, `toast.api.moveFailed`,
`settings.extraFolderPaths.restartRequired`, `toast.recipes.recipeSaved`,
`sidebar.dragDrop.moveUnsupported`, `checkpoints.modelTypes.diffusion_model`
(ja/ko keep the English loanword), `initialization.recipes.title`.

The only values that remain intentionally identical to `en.json` are non-translatable:
URL/path placeholders (`https://…`, `C:/…`), numeric presets (`5 (1080p), 6 (2K), 8 (4K)`),
example token lists (`character, concept, style(toon|toon_style)`), service/provider names
(`CivitAI → CivArchive → Archive DB`), and the external playlist title
(`help.updateVlogs.playlistTitle`, de: translated to "LoRA Manager-Update-Playlist").

Rule for `uiHelpers.workflow.noPromptTargets`: the second line (`Mark as → Send Prompt
Target`) quotes literal ComfyUI context-menu items — keep those menu labels in English in
every locale because that is what the user actually sees in ComfyUI.

License labels (`modals.model.license.*`): the restriction labels are now translated in all
locales (the sibling `creditRequired` has always been translated).

---

## 7. Workflow for agents and translators

### Adding a new UI string
1. Add the key to `locales/en.json` only.
2. Run `python scripts/sync_translation_keys.py` — it inserts the key into the other 9
   locales (as an English placeholder) preserving formatting.
3. Translate the new key in every locale, applying §1–§3 (placeholders verbatim, Recipe
   rule, term maps, register).
4. If the new string contains new terminology, extend §2 tables.

### Fixing a translation bug
1. Locate the key (dotted path) in the relevant locale file.
2. Check the corresponding `en.json` value and the actual caller (grep `static/js` or
   `web/comfyui` for the key) to learn which placeholders are passed.
3. Fix trivially; for normalization sweeps (e.g. "recette" → "Recipe"), do it file-wide for
   the offending keys only — do not touch unrelated lines.
4. If the bug is in `en.json` itself (R9), fix the source first, then re-sync and update all
   locales.

### Verification
```bash
pytest tests/i18n/test_i18n.py     # key parity + JSON validity + JS key references
python scripts/sync_translation_keys.py --dry-run   # shows which keys would change; add --verbose for per-key detail
npm test                           # frontend tests incl. i18n helpers
```

`pytest tests/i18n` only checks structure. Quality conventions in this document are not
machine-enforced — a human/agent review pass is required.

### Anti-patterns checklist
- [ ] Placeholders `{x}` / `{{x}}` differ from `en.json`
- [ ] Same source term translated 2+ ways in the same file (see §5)
- [ ] "Checkpoint" became a literal checkpoint; "recipe" became menu/prescription/food-cookbook
- [ ] Brand names translated or transliterated (LoRA, CivitAI, ComfyUI, …)
- [ ] Latin locale using full-width `：（）`; fr using `"` as apostrophe
- [ ] Mixed 你/您, du/Sie, tú/usted
- [ ] Full English sentences left behind (see §6)
- [ ] Register/typos/mojibake; source string is stale vs `en.json` (compare semantics, not
  just words)
