- .golangci.yml: набор линтеров под требования §14 (gosec, gocritic, sloglint, noctx, revive, depguard для запрета циклических зависимостей internal/*) - gofumpt вынесен из formatters golangci-lint v2.13 (сообщал о расхождениях, которые сам же не устранял) и применяется отдельным инструментом - make fmt/go-lint: проверка gofumpt + golangci-lint fmt --diff - scripts/gitleaks-scan.sh: поддержка gitleaks 8.19+ (dir) и старых версий (detect) - исправлены замечания линтеров: обработка ошибок Close, контекст в логах, NewRequestWithContext в тестах, комментарий к blank-import драйвера SQLite
