[split-required] Split 58 monoliths across Python, Go, TypeScript (Phases 1-3)
Phase 1 — Python (klausur-service): 5 monoliths → 36 files - dsfa_corpus_ingestion.py (1,828 LOC → 5 files) - cv_ocr_engines.py (2,102 LOC → 7 files) - cv_layout.py (3,653 LOC → 10 files) - vocab_worksheet_api.py (2,783 LOC → 8 files) - grid_build_core.py (1,958 LOC → 6 files) Phase 2 — Go (edu-search-service, school-service): 8 monoliths → 19 files - staff_crawler.go (1,402 → 4), policy/store.go (1,168 → 3) - policy_handlers.go (700 → 2), repository.go (684 → 2) - search.go (592 → 2), ai_extraction_handlers.go (554 → 2) - seed_data.go (591 → 2), grade_service.go (646 → 2) Phase 3 — TypeScript (admin-lehrer): 45 monoliths → 220+ files - sdk/types.ts (2,108 → 16 domain files) - ai/rag/page.tsx (2,686 → 14 files) - 22 page.tsx files split into _components/ + _hooks/ - 11 component files split into sub-components - 10 SDK data catalogs added to loc-exceptions - Deleted dead backup index_original.ts (4,899 LOC) All original public APIs preserved via re-export facades. Zero new errors: Python imports verified, Go builds clean, TypeScript tsc --noEmit shows only pre-existing errors. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
