- Add backend/ai/utils.py — parse_classification, parse_suggestions, strip_code_fences shared by all AI providers; removes duplicated private functions from anthropic_provider.py and openai_provider.py - Add backend/deps/utils.py — get_client_ip, parse_uuid request-parsing helpers; removes local _ip() variants from admin.py, auth.py, shares.py, folders.py - Add backend/storage/exceptions.py — canonical CloudConnectionError definition; all routers and backends import from here instead of redefining - Move validate_password_strength to backend/services/auth.py; removes duplicated _validate_password_strength from admin.py and auth.py Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
