Resolve all merge conflicts between our automation feature branch and current main (v0.163.0, 920 commits ahead). Conflicts resolved: - app/api/__init__.py: add automation_router alongside main's new routers (classification_rules, qr_auth, sessions, system_reset) - app/config.py: add main's new settings (dropbox_use_global_credentials, factory_reset_on_startup, enable_factory_reset) - app/models.py: add main's new models (ClassificationRuleModel, UserSession, QRLoginChallenge, SharePoint integration type) - app/utils/settings_service.py: merge automation_hooks_enabled with main's new metadata entries - docs/API.md: merge automation API docs with main's classification rules docs - docs/ConfigurationGuide.md: add factory reset settings - tests/conftest.py: import both AutomationHook and new main models Migration renumbered: - 037_add_automation_hooks → 040_add_automation_hooks - down_revision: 039_add_classification_rules (was 036_add_document_translation_fields) - Chain: 036 → 037 → 038 → 039 → 040 (automation hooks) For all non-automation files with conflicts, main's version was taken since our branch did not modify those files (conflicts were from a stale prior merge).
