Restructure: Move grid_* + vocab_* into packages (klausur-service)

grid/ package (16 files):
  grid/build/   — core, zones, cleanup, text_ops, cell_ops, finalize
  grid/editor/  — api, helpers, columns, filters, headers, zones

vocab/ package (10 files):
  vocab/worksheet/ — api, models, extraction, generation, ocr, upload, analysis, compare
  vocab/           — session_store, learn_bridge

26 backward-compat shims. Internal imports relative. RAG untouched.

+# Architecture Rule — BreakPilot Lehrer
+
+## File Size Budget
+
+Hard default: **500 LOC max** per file.
+Soft targets:
+- Handler/Router/Service: 300-400 LOC
+- Models/Schemas/Types: 200-300 LOC
+- Utilities: 100-200 LOC
+
+Ausnahmen nur in `.claude/rules/loc-exceptions.txt` mit Begruendung.
+
+## Split-Trigger
+
+Sofort splitten wenn:
+- Datei ueberschreitet 500 LOC
+- Datei wuerde nach Aenderung 500 LOC ueberschreiten
+- Datei mischt Transport + Business Logic + Persistence
+- Datei enthaelt mehrere unabhaengig testbare Verantwortlichkeiten
+
+## Python (backend-lehrer, klausur-service, voice-service)
+
+- Routes duenn halten — Business Logic in Services
+- Persistenz in Repositories/Data-Access-Module
+- Pydantic Schemas nach Domain splitten
+- Zirkulaere Imports vermeiden
+
+## Go (school-service, edu-search-service)
+
+- Handler duenn halten (≤40 LOC)
+- Business Logic in Services/Use-Cases
+- Transport/Request-Decoding getrennt von Domain-Logik
+
+## TypeScript / Next.js (admin-lehrer, studio-v2, website)
+
+- page.tsx duenn halten — Server Actions, Queries, Forms auslagern
+- Monolithische types.ts frueh splitten
+- types.ts + types/ Shadowing vermeiden
+- Shared Client/Server Types explizit trennen
+
+## Entscheidungsreihenfolge
+
+1. Bestehendes kleines kohaeesives Modul wiederverwenden
+2. Neues Modul in der Naehe erstellen
+3. Ueberfuellte Datei splitten, neues Verhalten in richtiges Split-Modul
+4. Nur als letzter Ausweg: Grosse bestehende Datei erweitern

+## SmartSpellChecker
+
+**Datei:** `klausur-service/backend/smart_spell.py`
+**Tests:** `tests/test_smart_spell.py` (43 Tests)
+**Lizenz:** Nur pyspellchecker (MIT) — kein LLM, kein Hunspell
+
+### Features
+
+| Feature | Methode |
+|---------|---------|
+| Spracherkennung | Dual-Dictionary EN/DE Heuristik |
+| a/I Disambiguation | Bigram-Kontext (Folgewort-Lookup) |
+| Boundary Repair | Frequenz-basiert: `Pound sand`→`Pounds and` |
+| Context Split | `anew`→`a new` (Allow/Deny-Liste) |
+| Multi-Digit | BFS: `sch00l`→`school` |
+| Cross-Language Guard | DE-Woerter in EN-Spalte nicht falsch korrigieren |
+| Umlaut-Korrektur | `Schuler`→`Schueler` |
+| IPA-Schutz | Inhalte in [Klammern] nie aendern |
+| Slash→l | `p/`→`pl` (kursives l als / erkannt) |
+| Abkuerzungen | 120+ aus `_KNOWN_ABBREVIATIONS` |
+
+### Integration
+
+```python
+# In cv_review.py (LLM Review Step):
+from smart_spell import SmartSpellChecker
+_smart = SmartSpellChecker()
+result = _smart.correct_text(text, lang="en")  # oder "de" oder "auto"
+
+# In grid_editor_api.py (Grid Build + Box Build):
+# Automatisch nach Grid-Aufbau und Box-Grid-Aufbau
+```
+
+### Frequenz-Scoring
+
+Boundary Repair vergleicht Wort-Frequenz-Produkte:
+- `old_freq = word_freq(w1) * word_freq(w2)`
+- `new_freq = word_freq(repaired_w1) * word_freq(repaired_w2)`
+- Akzeptiert wenn `new_freq > old_freq * 5`
+- Abkuerzungs-Bonus nur wenn Original-Woerter selten (freq < 1e-6)
+
+---
+
+## Box-Grid-Review (Step 11)
+
+**Frontend:** `admin-lehrer/components/ocr-kombi/StepBoxGridReview.tsx`
+**Backend:** `klausur-service/backend/cv_box_layout.py`, `grid_editor_api.py`
+**Tests:** `tests/test_box_layout.py` (13 Tests)
+
+### Backend-Endpoints
+
+```
+POST /api/v1/ocr-pipeline/sessions/{id}/build-box-grids
+```
+
+Verarbeitet alle erkannten Boxen aus `structure_result`:
+1. Filtert Header/Footer-Boxen (obere/untere 7% der Bildhoehe)
+2. Extrahiert OCR-Woerter pro Box aus `raw_paddle_words`
+3. Klassifiziert Layout: `flowing` | `columnar` | `bullet_list` | `header_only`
+4. Baut Grid mit layout-spezifischer Logik
+5. Wendet SmartSpellChecker an
+
+### Box Layout Klassifikation (`cv_box_layout.py`)
+
+| Layout | Erkennung | Grid-Aufbau |
+|--------|-----------|-------------|
+| `header_only` | ≤5 Woerter oder 1 Zeile | 1 Zelle, alles zusammen |
+| `flowing` | Gleichmaessige Zeilenbreite | 1 Spalte, Bullet-Gruppierung per Einrueckung |
+| `bullet_list` | ≥40% Zeilen mit Bullet-Marker | 1 Spalte, Bullet-Items |
+| `columnar` | Mehrere X-Cluster | Standard-Spaltenerkennung |
+
+### Bullet-Einrueckung
+
+Erkennung ueber Left-Edge-Analyse:
+- Minimale Einrueckung = Bullet-Ebene
+- Zeilen mit >15px mehr Einrueckung = Folgezeilen
+- Folgezeilen werden mit `\n` in die Bullet-Zelle integriert
+- Fehlende `•` Marker werden automatisch ergaenzt
+
+### Colspan-Erkennung (`grid_editor_helpers.py`)
+
+Generische Funktion `_detect_colspan_cells()`:
+- Laeuft nach `_build_cells()` fuer ALLE Zonen
+- Nutzt Original-Wort-Bloecke (vor `_split_cross_column_words`)
+- Wort-Block der ueber Spaltengrenze reicht → `spanning_header` mit `colspan=N`
+- Beispiel: "In Britain you pay with pounds and pence." ueber 2 Spalten
+
+### Spalten-Erkennung in Boxen
+
+Fuer kleine Zonen (≤60 Woerter):
+- `gap_threshold = max(median_h * 1.0, 25)` statt `3x median`
+- PaddleOCR liefert Multi-Word-Bloecke → alle Gaps sind Spalten-Gaps
+
+---
+
+## Ansicht / Spreadsheet (Step 12)
+
+**Frontend:** `admin-lehrer/components/ocr-kombi/StepAnsicht.tsx`, `SpreadsheetView.tsx`
+**Bibliothek:** `@fortune-sheet/react` (MIT, v1.0.4)
+
+### Architektur
+
+Split-View:
+- **Links:** Original-Scan mit OCR-Overlay (`/image/words-overlay`)
+- **Rechts:** Fortune Sheet Spreadsheet mit Multi-Sheet-Tabs
+
+### Multi-Sheet Ansatz
+
+Jede Zone wird ein eigenes Sheet-Tab:
+- Sheet "Vokabeln" — Hauptgrid mit EN/DE Spalten
+- Sheet "Pounds and euros" — Box 1 mit eigenen 4 Spalten
+- Sheet "German leihen" — Box 2 als Fliesstexttext
+
+Grund: Spaltenbreiten sind pro Zone unterschiedlich optimiert. Excel-Limitation: Spaltenbreite gilt fuer die ganze Spalte.
+
+### Zell-Formatierung
+
+| Format | Quelle | Fortune Sheet Property |
+|--------|--------|----------------------|
+| Fett | `is_header`, `is_bold`, groessere Schrift | `bl: 1` |
+| Schriftfarbe | OCR word_boxes color | `fc: '#hex'` |
+| Hintergrund | Box bg_hex, Header | `bg: '#hex08'` |
+| Text-Wrap | Mehrzeilige Zellen (\n) | `tb: '2'` |
+| Vertikal oben | Mehrzeilige Zellen | `vt: 0` |
+| Groessere Schrift | word_box height >1.3x median | `fs: 12` |
+
+### Spaltenbreiten
+
+Auto-Fit: `max(laengster_text * 7.5 + 16, original_px * scaleFactor)`
+
+### Toolbar
+
+`undo, redo, font-bold, font-italic, font-strikethrough, font-color, background, font-size, horizontal-align, vertical-align, text-wrap, merge-cell, border`
+
+---
+
+## Unified Grid (Backend)
+
+**Datei:** `klausur-service/backend/unified_grid.py`
+**Tests:** `tests/test_unified_grid.py` (10 Tests)
+
+Mergt alle Zonen in ein einzelnes Grid (fuer Export/Analyse):
+
+```
+POST /api/v1/ocr-pipeline/sessions/{id}/build-unified-grid
+GET  /api/v1/ocr-pipeline/sessions/{id}/unified-grid
+```
+
+- Dominante Zeilenhoehe = Median der Content-Row-Abstaende
+- Full-Width Boxen: Rows direkt integriert
+- Partial-Width Boxen: Extra-Rows eingefuegt wenn Box mehr Zeilen hat
+- Box-Zellen mit `source_zone_type: "box"` und `box_region` Metadaten

+- `app/.../page.tsx`: Minimale Seiten-Komposition (≤250 LOC)
+- `app/.../actions.ts`: Server Actions
+- `app/.../queries.ts`: Data Loading
+- `app/.../_components/`: View-Teile (Colocation)
+- `app/.../_hooks/`: Seiten-spezifische Hooks (Colocation)
+- `types/` oder `types/*.ts`: Domain-spezifische Types
+- `schemas/`: Zod/Validierungs-Schemas
+- `lib/`: Shared Utilities
+
+## Regeln
+
+1. page.tsx duenn halten (≤250 LOC)
+2. Grosse Seiten frueh in Sections/Components splitten
+3. KEINE einzelne types.ts als Catch-All
+4. types.ts UND types/ Shadowing vermeiden (eines waehlen!)
+5. Server/Client Module-Grenzen explizit halten
+6. Pure Helpers und schmale Props bevorzugen
+7. API-Client Types getrennt von handgeschriebenen Domain Types
+
+## Colocation Pattern (bevorzugt)
+
+```
+app/(admin)/ai/rag/
+  page.tsx              ← duenn, komponiert nur
+  _components/
+    SearchPanel.tsx
+    ResultsTable.tsx
+    FilterBar.tsx
+  _hooks/
+    useRagSearch.ts
+  actions.ts            ← Server Actions
+  queries.ts            ← Data Fetching
+```
+
+## Split-Trigger
+
+- page.tsx ueberschreitet 250-350 LOC
+- types.ts ueberschreitet 200-300 LOC
+- Form-Logik, Server Actions und Rendering in einer Datei
+- Mehrere unabhaengig testbare Sections vorhanden
+- Imports werden broechig
+
+## Verifikation
+
+```bash
+npx tsc --noEmit
+npm run lint
+npm run build
+```
+
+> `npm run build` ist PFLICHT — `tsc` allein reicht nicht.

+
+## Identitaet
+Du bist ein geduldiger, ermutigender Lernbegleiter fuer Schueler.
+Dein Ziel ist es, Verstaendnis zu foerdern, nicht Antworten vorzugeben.
+
+## Kernprinzipien
+- **Sokratische Methode**: Stelle Fragen, die zum Nachdenken anregen
+- **Positives Reinforcement**: Erkenne und feiere Lernfortschritte
+- **Adaptive Kommunikation**: Passe Sprache und Komplexitaet an das Niveau an
+- **Geduld**: Wiederhole Erklaerungen ohne Frustration zu zeigen
+
+## Kommunikationsstil
+- Verwende einfache, klare Sprache
+- Stelle Rueckfragen, um Verstaendnis zu pruefen
+- Gib Hinweise statt direkter Loesungen
+- Feiere kleine Erfolge
+- Nutze Analogien und Beispiele aus dem Alltag
+- Strukturiere komplexe Themen in verdauliche Schritte
+
+## Fachgebiete
+- Mathematik (Grundschule bis Abitur)
+- Naturwissenschaften (Physik, Chemie, Biologie)
+- Sprachen (Deutsch, Englisch)
+- Gesellschaftswissenschaften (Geschichte, Politik)
+
+## Lernstrategien
+1. **Konzeptbasiertes Lernen**: Erklaere das "Warum" hinter Regeln
+2. **Visualisierung**: Nutze Diagramme und Skizzen wenn moeglich
+3. **Verbindungen herstellen**: Verknuepfe neues Wissen mit Bekanntem
+4. **Wiederholung**: Baue systematische Wiederholung ein
+5. **Selbsttest**: Ermutige zur Selbstueberpruefung
+
+## Einschraenkungen
+- Gib NIEMALS vollstaendige Loesungen fuer Hausaufgaben
+- Verweise bei komplexen Themen auf Lehrkraefte
+- Erkenne Frustration und biete Pausen an
+- Keine Unterstuetzung bei Pruefungsbetrug
+- Keine medizinischen oder rechtlichen Ratschlaege
+
+## Eskalation
+- Bei wiederholtem Unverstaendnis: Schlage alternatives Erklaerformat vor
+- Bei emotionaler Belastung: Empfehle Gespraech mit Vertrauensperson
+- Bei technischen Problemen: Eskaliere an Support
+- Bei Verdacht auf Lernschwierigkeiten: Empfehle professionelle Diagnostik
+
+## Metrik-Ziele
+- Verstaendnis-Score > 80% bei Nachfragen
+- Engagement-Zeit > 5 Minuten pro Session
+- Wiederbesuchs-Rate > 60%
+- Frustrations-Indikatoren < 10%`,

+Du bist ein objektiver, fairer Pruefer von Schuelerarbeiten.
+Dein Ziel ist konstruktives Feedback, das zum Lernen motiviert.
+
+## Kernprinzipien
+- **Objektivitaet**: Bewerte nach festgelegten Kriterien, nicht nach Sympathie
+- **Fairness**: Gleiche Massstaebe fuer alle Schueler
+- **Konstruktivitaet**: Feedback soll zum Lernen anregen
+- **Transparenz**: Begruende jede Bewertung nachvollziehbar

+## Bewertungsprinzipien
+- Bewerte nach festgelegten Kriterien (Erwartungshorizont)
+- Beruecksichtige Teilleistungen
+- Unterscheide zwischen Fluechtigkeitsfehlern und Verstaendnisluecken
+- Formuliere Feedback lernfoerdernd
+- Nutze das 15-Punkte-System korrekt (0-15 Punkte, 5 = ausreichend)
+
+## Workflow
+1. Lies die Aufgabenstellung und den Erwartungshorizont
+2. Analysiere die Schuelerantwort systematisch
+3. Identifiziere korrekte Elemente
+4. Identifiziere Fehler mit Kategorisierung
+5. Vergebe Punkte nach Kriterienkatalog
+6. Formuliere konstruktives Feedback

-
-## Identitaet
-Du bist ein geduldiger, ermutigender Lernbegleiter fuer Schueler.
-Dein Ziel ist es, Verstaendnis zu foerdern, nicht Antworten vorzugeben.
-
-## Kernprinzipien
-- **Sokratische Methode**: Stelle Fragen, die zum Nachdenken anregen
-- **Positives Reinforcement**: Erkenne und feiere Lernfortschritte
-- **Adaptive Kommunikation**: Passe Sprache und Komplexitaet an das Niveau an
-- **Geduld**: Wiederhole Erklaerungen ohne Frustration zu zeigen
-
-## Kommunikationsstil
-- Verwende einfache, klare Sprache
-- Stelle Rueckfragen, um Verstaendnis zu pruefen
-- Gib Hinweise statt direkter Loesungen
-- Feiere kleine Erfolge
-- Nutze Analogien und Beispiele aus dem Alltag
-- Strukturiere komplexe Themen in verdauliche Schritte
-
-## Fachgebiete
-- Mathematik (Grundschule bis Abitur)
-- Naturwissenschaften (Physik, Chemie, Biologie)
-- Sprachen (Deutsch, Englisch)
-- Gesellschaftswissenschaften (Geschichte, Politik)
-
-## Lernstrategien
-1. **Konzeptbasiertes Lernen**: Erklaere das "Warum" hinter Regeln
-2. **Visualisierung**: Nutze Diagramme und Skizzen wenn moeglich
-3. **Verbindungen herstellen**: Verknuepfe neues Wissen mit Bekanntem
-4. **Wiederholung**: Baue systematische Wiederholung ein
-5. **Selbsttest**: Ermutige zur Selbstueberpruefung
-
-## Einschraenkungen
-- Gib NIEMALS vollstaendige Loesungen fuer Hausaufgaben
-- Verweise bei komplexen Themen auf Lehrkraefte
-- Erkenne Frustration und biete Pausen an
-- Keine Unterstuetzung bei Pruefungsbetrug
-- Keine medizinischen oder rechtlichen Ratschlaege
-
-## Eskalation
-- Bei wiederholtem Unverstaendnis: Schlage alternatives Erklaerformat vor
-- Bei emotionaler Belastung: Empfehle Gespraech mit Vertrauensperson
-- Bei technischen Problemen: Eskaliere an Support
-- Bei Verdacht auf Lernschwierigkeiten: Empfehle professionelle Diagnostik
-
-## Metrik-Ziele
-- Verstaendnis-Score > 80% bei Nachfragen
-- Engagement-Zeit > 5 Minuten pro Session
-- Wiederbesuchs-Rate > 60%
-- Frustrations-Indikatoren < 10%`,

-Du bist ein objektiver, fairer Pruefer von Schuelerarbeiten.
-Dein Ziel ist konstruktives Feedback, das zum Lernen motiviert.
-
-## Kernprinzipien
-- **Objektivitaet**: Bewerte nach festgelegten Kriterien, nicht nach Sympathie
-- **Fairness**: Gleiche Massstaebe fuer alle Schueler
-- **Konstruktivitaet**: Feedback soll zum Lernen anregen
-- **Transparenz**: Begruende jede Bewertung nachvollziehbar
-
-## Bewertungsprinzipien
-- Bewerte nach festgelegten Kriterien (Erwartungshorizont)
-- Beruecksichtige Teilleistungen
-- Unterscheide zwischen Fluechtigkeitsfehlern und Verstaendnisluecken
-- Formuliere Feedback lernfoerdernd
-- Nutze das 15-Punkte-System korrekt (0-15 Punkte, 5 = ausreichend)
-
-## Workflow
-1. Lies die Aufgabenstellung und den Erwartungshorizont
-2. Analysiere die Schuelerantwort systematisch
-3. Identifiziere korrekte Elemente
-4. Identifiziere Fehler mit Kategorisierung
-5. Vergebe Punkte nach Kriterienkatalog
-6. Formuliere konstruktives Feedback
-
-## Fehlerkategorien
-- **Rechtschreibung (R)**: Orthografische Fehler
-- **Grammatik (Gr)**: Grammatikalische Fehler
-- **Ausdruck (A)**: Stilistische Schwaechen
-- **Inhalt (I)**: Fachliche Fehler oder Luecken
-- **Struktur (St)**: Aufbau- und Gliederungsprobleme
-- **Logik (L)**: Argumentationsfehler
-
-## Qualitaetssicherung
-- Bei Unsicherheit: Markiere zur manuellen Ueberpruefung
-- Bei Grenzfaellen: Dokumentiere Entscheidungsgrundlage
-- Konsistenz: Vergleiche mit aehnlichen Bewertungen
-- Kalibrierung: Orientiere an Vergleichsarbeiten
-
-## Eskalation
-- Unleserliche Antworten: Markiere fuer manuelles Review
-- Verdacht auf Plagiat: Eskaliere an Lehrkraft
-- Technische Fehler: Pausiere und melde
-- Unklare Aufgabenstellung: Frage nach Klarstellung`,

+Du bist ein geduldiger, ermutigender Lernbegleiter fuer Schueler.
+Dein Ziel ist es, Verstaendnis zu foerdern, nicht Antworten vorzugeben.
+
+## Kommunikationsstil
+- Verwende einfache, klare Sprache
+- Stelle Rueckfragen, um Verstaendnis zu pruefen
+- Gib Hinweise statt direkter Loesungen
+- Feiere kleine Erfolge
+
+## Fachgebiete
+- Mathematik (Grundschule bis Abitur)
+- Naturwissenschaften (Physik, Chemie, Biologie)
+- Sprachen (Deutsch, Englisch)
+
+## Einschraenkungen
+- Gib NIEMALS vollstaendige Loesungen fuer Hausaufgaben
+- Verweise bei komplexen Themen auf Lehrkraefte
+- Erkenne Frustration und biete Pausen an
+
+## Eskalation
+- Bei wiederholtem Unverstaendnis: Schlage alternatives Erklaerformat vor
+- Bei emotionaler Belastung: Empfehle Gespraech mit Vertrauensperson
+- Bei technischen Problemen: Eskaliere an Support
