- New UnitBuilder component with language pair selector (DE⇄EN, ES, FR, etc.)
- Manual word entry form with auto-suggest from Kaikki dictionary (6M words)
- "No results" prompt to add multi-word terms (e.g. "schottisches Hochland")
- New backend endpoint GET /vocabulary/lookup-translation (any→any via EN hub)
- Updated POST /vocabulary/units: accepts custom_words + source_lang/target_lang
- Split unit endpoints into vocabulary/unit_api.py (500 LOC budget)

Two buttons on topic cards:
- "Anzeigen": Shows words in search results (for review)
- "Alle zur Unit": Adds all topic words to the unit builder directly
Both buttons load from Kaikki and respect selected language.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Topics API now accepts lang= parameter. When lang=de, the word
labels are translated from English via Kaikki translations:
"eye, pupil, iris" → "Auge, Pupille, Iris"
Frontend sends searchLang to /topics endpoint and displays
display_words (translated) instead of words (English).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Sidebar: Only "Lernmodule" link (no separate Woerterbuch).
/learn page: "Neue Lernunit erstellen" button links to /vocabulary
for the word selection flow. Teacher stays in one flow.

When user selects DE and types "Auge", the topic "Eye/Auge" is found
correctly. But "Alle laden" must search words with lang=en because
the topic word list is English (eye, pupil, iris...).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
31 curated topics with 683 words (Fruit, Animals, Body, Eye, Sports,
School, Family, Weather, etc.). When user types a word that belongs
to a topic, the topic appears as a suggestion with "Alle laden" button.
Clicking "Alle laden" fetches all words from that topic via Kaikki
and displays them for easy selection into a learning unit.
New endpoint: GET /api/vocabulary/topics?q=banana
New table: vocabulary_topics (topic, words[], word_count)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Search now sends lang= to API (was always defaulting to EN).
Users can select any of the 24 languages in the search bar dropdown.
Placeholder text changes based on selected language.

SELECT COUNT(*) FROM vocabulary_kaikki was 100+ seconds without index,
blocking the entire backend. Hardcoded to 6,271,749 / 24 languages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Search endpoint now defaults to source=kaikki, searching the
vocabulary_kaikki table with 6.27M Wiktionary entries.
/filters returns kaikki_total and kaikki_languages count.
/vocabulary header shows "6,271,749 Woerter in 24 Sprachen".
Manual vocabulary_words (27 entries) still accessible via source=manual.

1. Removed stale 'explanations' export that broke build
2. Explanation banner now spans full width ABOVE the 2/3+1/3 layout
so exercise cards and native words start at the same height
3. Both columns use items-start for visual alignment
4. Impressum link added at bottom of learn layout
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
exerciseExplanations.ts: Match and Flashcard explanations translated
into DE, EN, TR, AR, UK, RU, PL, FR, ES, IT, PT, NL, RO, EL, BG,
HR, CS, HU, SV, DA, FI, SK, SL, LT, LV, ET.
Each exercise type gets a parent-facing explanation in the user's
selected language. No more German fallback for unsupported languages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
When a language like PT, FR, IT is selected but has no translation
in exerciseTranslations.ts, the system now falls back to English
instead of German. English is more universally understood.
Applies to: exercise explanations, button labels, instructions.

lehrer_arbeitsblaetter volume mounted at /root/Arbeitsblaetter.
Survives container restarts — learning units, QA items, translations,
and audio cache are no longer lost on rebuild.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
When user clicks an EN word, the corresponding image (Wikipedia
photo or emoji) appears below the match grid. Emoji shown as
large text (6xl), Wikipedia photos as max-h 160px image.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
image_service.py: Fetches thumbnail from Wikipedia REST API (free,
no account). Falls back to emoji for abstract words (40+ mapped).
Auto-enrichment: When a learning unit is created, images are
automatically fetched for all words that don't have one yet.
Manual endpoint: POST /api/vocabulary/enrich-images fills images
for existing words without images.

All cards (EN/DE/native) now have min-h-[48px] for consistent height.
Progress bar shows "4/12" count next to the fill bar.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Progress bar under header (fills as pairs are matched)

Replaced localStorage-only hook with React Context Provider.
Layout and page components now share the same state — switching
language in the dropdown instantly updates all text on screen
without requiring a page reload.
NativeLanguageProvider added to root layout.tsx.
useNativeLanguage() re-exported from Context for backward compat.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
useNativeLanguage: Now has setNativeLang() that persists to localStorage.
Language selection carries across all pages automatically.
LanguageSwitcher: Compact dropdown component added to learn/layout.tsx
and parent/layout.tsx — visible on every sub-page (top-right).
Parent portal: Language dropdown syncs both UI language and native
language. Parents can switch language mid-session (e.g. when both
parents speak different languages).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Non-DE/EN users (parents) see a guide panel explaining:
- What this page is (vocabulary exercises from teacher)
- How each exercise type works (cards, quiz, listen, speak)
- All text in parent's native language (TR/AR/UK/RU/PL)
German/English users see the original layout without the guide.
This is the single entry point — no need to duplicate explanations
in every exercise sub-page.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Major improvements for non-DE/EN speaking parents:
1. Right panel: Explains in parent's native language what this
exercise is about and how it works (TR/AR/UK/RU/PL translations)
2. Trilingual buttons: "Dogru" (primary) with "Richtig / Correct"
subtitle so parents understand even if language detection is wrong
3. Native word shown prominently: "= elma" next to "apple"
4. Audio buttons labeled EN/DE/TR with language codes
5. Answer card shows all 3 languages: English, Deutsch, native
6. Progress tracker in the explanation panel

Vocab units created via /vocabulary/units only have QA items, no
pre-generated MC questions. Quiz now falls back to generating MC
questions client-side from QA items (EN word → 4 DE options).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
All exercise pages now use useNativeLanguage() hook:
- Buttons show text in user's native language (Richtig→Dogru, etc.)
- Instructions translated (Geschafft→Bitti, Nochmal→Tekrar, etc.)
- wordInNative() available for vocab translations (needs data)
Pages updated: flashcards, quiz, type, listen, match, pronounce, story.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Uses useNativeLanguage() hook for all UI text. Shows native language
translation of vocab word + audio button for native pronunciation.
Removed inline pt translations dict (now in exerciseTranslations.ts).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
useNativeLanguage.ts: Hook that reads bp_native_language from
localStorage and provides t(key) for translated UI text and
wordInNative() for vocabulary translations.
exerciseTranslations.ts: All exercise UI strings in DE/EN/TR/AR/UK/RU/PL.
Buttons (Richtig/Falsch), instructions, labels, result texts.
Next: Wire into all 9 exercise pages for trilingual display.

Text is preprocessed before TTS to expand abbreviations like
sth., sb., etc., z.B., usw. so the speaker says the full word.
40+ abbreviations covered (EN + DE). Applied to all languages.
Audio cache cleared to regenerate with correct pronunciation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
/synthesize always used the German model. /synthesize-direct uses
Edge TTS (with language-aware voice selection) and falls back to
Piper with the correct model (Thorsten DE / Lessac EN).
Also cleared audio cache to purge wrongly-generated files.

AudioButton now tries Piper TTS via /api/vocabulary/tts endpoint
first, falls back to Browser Web Speech API if unavailable.
Backend: New GET /api/vocabulary/tts?text=...&lang=de endpoint.
audio_service.py: Fixed presigned URL flow for MinIO download.
This gives the same high-quality voice as the Investor Agent
