[split-required] Split remaining Python monoliths (Phase 1 continued)
klausur-service (7 monoliths): - grid_editor_helpers.py (1,737 → 5 files: columns, filters, headers, zones) - cv_cell_grid.py (1,675 → 7 files: build, legacy, streaming, merge, vocab) - worksheet_editor_api.py (1,305 → 4 files: models, AI, reconstruct, routes) - legal_corpus_ingestion.py (1,280 → 3 files: registry, chunking, ingestion) - cv_review.py (1,248 → 4 files: pipeline, spell, LLM, barrel) - cv_preprocessing.py (1,166 → 3 files: deskew, dewarp, barrel) - rbac.py, admin_api.py, routes/eh.py remain (next batch) backend-lehrer (1 monolith): - classroom_engine/repository.py (1,705 → 7 files by domain) All re-export barrels preserve backward compatibility. Zero import errors verified. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
