- 400 → 422 для всех ошибок валидации входных данных (handlers: export, quote, sync, vendor_spec, partnumber_books, pricelist) - SQL-запросы вынесены из handlers в localdb (partnumber_books, pricelist, support_bundle); ValidateMariaDBConnection перенесён в internal/db/validate.go - List-ответы унифицированы: ключ items, поля total_count/page/per_page/total_pages (component, pricelist, partnumber_books); шаблоны обновлены - Молчаливые ошибки заменены на slog.Warn/Error (support_bundle, vendor_spec, component, configuration, local_configuration, localdb) - N+1 запросы устранены: batch-запросы в export.go и vendor_workspace_import.go - fmt.Println → slog в cmd/ (qfs, migrate, migrate_ops_projects, migrate_project_updated_at) - Заголовки recovery/verify добавлены во все 28 SQL-миграций - Добавлены bible-local/runtime-flows.md и bible-local/decisions/ - Обновлён субмодуль bible до v0.2.0-13 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
