Replace the placeholder "Koordinaten" step with an LLM review step that sends vocab entries to qwen3:30b-a3b via Ollama for OCR error correction (e.g. "8en" → "Ben"). Teachers can review, accept/reject individual corrections in a diff table before applying them. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
